Routine brake system maintenance
The braking system is the most important system on a car. If the brakes don't work properly, the result can be disastrous. So the good brakes are essential for safety.
There are two completely independent braking systems on a car. One is the service brake, and the other is parking brake. The service brake acts to slow, stop, or hold the vehicle during normal driving. They are foot-operated by the driver depressing and releasing the brake pedal. The parking brake's purposes are to hold a car stationary while it is unattended, and to keep the car from rolling on unleveled ground. It is also called the handbrake.
Basically, all car brakes are friction brakes. When the driver applies the brake, the control device will force brake shoes or pads against the rotating brake drums or discs at wheels. Friction between the shoes or pads and the drums or disks then slows or stops the wheels so that the car is braked.
Disc brake
Disc brakes are used on the front wheels of most cars and on all four wheels on many cars.
The main components of a disc brake are the brake pads, the caliper which contains a piston, and the rotor which is mounted to the hub.
The disc brake is a lot like the brakes on a bicycle. Bicycle brakes have a caliper, which squeezes the brake pads against the wheel. In a disc brake, the brake pads squeeze the rotor instead of the wheel, and the force is transmitted hydraulically instead of through a cable. Friction between the pads and the disc slows the disc down.
A moving car has a certain amount of kinetic energy, and the brakes have to remove this energy from the car in order to stop it. The brakes convert the kinetic energy to heat generated by the friction between the pads and the disc, so the car stops.
Drum brake
So if disk brakes are so great, how come we still have cars with drum brakes? The reason is cost. While all most vehicles for many years have disk brakes on the front wheels, drum brakes are cheaper to produce for the rear wheels. Drum brake is shown in Fig.
Drum brakes consist of a backing plate, brake shoes, brake drum, wheel cylinder, return springs and an automatic or self-adjusting system. When you apply the brakes, the wheel cylinder pushes the brake shoes into contact with the machined surface on the inside of the drum. When the pressure is released, return springs pull the shoes back to their rest position. As the brake linings wear, the shoes must travel a greater distance to reach the drum. When the distance reaches a certain point, a self-adjusting mechanism automatically reacts by
adjusting the rest position of the shoes so that they are closer to the drum.
Hydraulic Brake Systems
When the operator steps on the brake pedal, the brake pedal operates a hydraulic system.
The typical brake system is composed of the following basic components
(1) Master cylinder. That is directly connected to the brake pedal, converts your foot's mechanical pressure into hydraulic pressure.
(2) Brake lines and brake hoses, they connect the master cylinder to the wheel cylinders located at each wheel.
(3) Brake fluid: that is special oil that has special properties. It is designed to withstand cold temperature without thickening as well as very high temperature without boiling.
In the brake system, master cylinder contains two separate sections, there is a piston in each section and both pistons are connected to a brake pedal in the driver's compartment. When the brake is pushed down, brake fluid is sent from the master cylinder to the wheels. At the wheels, the fluid pushes shoes, or pads, against revolving drums or disks, which can slow and stop car. This slows or stops the revolving wheels, which, in turn, slow or stop the car.
Routine maintenance of automobile brake fluid: Usually brake fluid maintenance period of 2 years or 48,000 km. Recommended brake fluid on the maintenance period, the European car manufacturers generally set a few years; and Japan and the United States car manufacturers are generally in their owner's manual have detailed descriptions. The abs function with anti-lock braking system, brake fluid and timely supplement is especially important. This is mainly due to energy storage in the pollution of dust and moisture of the body will lead to expensive failure, and thus laid security risk when vehicle braking force owners to find weak, you can use brake fluid test strips humidity assisted analysis of whether there is any fault of defect caused by brake fluid. If the brake fluid for the failure of the root causes of lack of sufficient quantity to be added in time brake fluid. By the brake fluid tank vent in a normal infiltration (or when tank lid open non-regular access to) the moisture and dust reduced brake fluid maintenance cycle. Maintenance of the brake fluid in the same time, must not neglect the wheel brake parts.
Auto brake pad, brake drum, rotating body, and brake calipers: the current drive vehicle for leading the trend, people are concerned about how to play the 2 / 3 of the front brake lines brake tasks for scientific and effective maintenance. Now, after a variety of drive, all-wheel drive, trucks and suv blossom everywhere, people "before re-light after the" traditional concept has gradually changed.
Gradually replace the asbestos linings in the semi-metallic brake pad will cause the whole surface of rotating serious wear and tear. Brake parts on the car wheel or brake pad inspection is a complex task, not simply from a visual look at both sides of the front brake
pads wear the middle point. In actual operation, even if the brake caliper of open distance just to let you see both sides of the brake pad, it does not mean we can be handy, unimpeded operation of the. In addition, the popularization of brake shield, and the brake pad of rotating the contact surface is multi-block, hard look. As for the rear wheel with disc brake, it is hidden, is difficult to comprehend the appearance.
Typically, the only system in the apparent leak, we will focus on checking brake fluid sealing. The comprehensive system of inspection, including the traditional static checking (that is, to find leaks in situ static) and dynamic checks (ie check the seal during braking). In any case, when the vehicle braking system to maintain up to 48 000 km driving range, they need the vehicle's braking system to conduct a comprehensive professional maintenance Brake rotating body of minor scratches do not cause illness. But since the fastening nut tightening force thickness of inequality and uneven brake rotating body rotation caused by excessive wear and tear will seriously affect the braking performance. To reduce weight, many rotating body size using unconventional structure, which is difficult to meet some of the machine tool clamping the basic requirements. If you find a rotating body has been processed, then follow the same axle of the second rotating body is only the size of its replacement. In theory, you can only replace a rotating body, but to get the best balance between braking effect, or the proposed replacement with two on the same axle rotating body. The proposal also applies to vehicles during braking, brake caliper piston through the experience back movement, we can complete the key features of the automatic brake calipers inspection. If the brake caliper piston back position is unsound, please replace a new brake caliper; If you want to discharge or filling brake fluid, make sure relief valve can be normally open; if the relief valve setting, replace the new The brake caliper.
If the asbestos linings have worn 3.175mm, this time even under light loading, the security of driving range has also been very limited. Also, if needed at this time of high load brake, the wear lining weak braking force will make the traffic safety compromised.
Some rear disc brake, rear-drive rotary body with a cap, the cap body also acts as a rotary brake drum. There are many car owners often overlook the parking brake will cancel the direct-drive vehicles, the rotating body and the brake shoes in direct metal - metal friction, the result is bound to cause a rotating body, brake pads and brake shoes of serious wear and tear.

汽车制动系统的日常维修保养
制动系统是汽车上最重要的系统。如果制动系统不能正常工作，后果不堪设想。因此良好的制动系统是安全所必需的。
车上有两种完全独立的制动系统，一种是行车制动，一种是驻车制动。行车制动能够在汽车正常行驶过程中使汽车减速或停车，这个过程是通过驾驶员踩下或松开制动踏板实现的。驻车制动也叫手刹，它的作用是在车辆停止时，保持车辆不动，防止车轮滚动。
基本上所有的制动都是摩擦制动。当踩下刹车时，控制机构推动制动蹄片或制动块，阻止制动鼓或制动盘转动。制动蹄片或制动块与制动鼓或制动盘之间产生摩擦，降低或停止车轮的转动速度，以使汽车制动。
盘式制动器
大多数汽车的前轮和所有四轮驱动汽车的四个轮子采用盘式制动器。
盘式制动器的主要组成部分有摩擦+t-g~，内部有活塞、卡钳和固定在轮毂上的转子。
盘式制动器有点像自行车的制动系统。自行车的制动系统有个卡钳，与制动衬块压紧，制动衬块与车轮固定在一起，而汽车的盘式制动器中，制动衬块与转子压g-．，而不是与车轮，并采用制动液传递动力，而不是钢丝绳。摩擦衬块与制动盘之间的摩擦力使制动盘的转速降低。行驶中的汽车有一定动能，制动器必须将此能量从汽车上移除，汽车才能停下来。只有通过摩擦衬块和制动盘之间的摩擦，制动器才能将动能转化成热能，汽车才能停下。
鼓式制动器
既然盘式制动器好，为什么仍有很多车采用鼓式制动器呢?原因是价格便宜。多年来，大多数汽车前轮采用盘式制动器，后轮采用鼓式制动器。鼓式制动器。
鼓式制动器包括底板、制动蹄、制动鼓、轮缸、回位弹簧和机械的或自动的调节装置。当制动器工作时，轮缸推动制动蹄，使其与制动鼓的内侧面接触。当制动压力解除，在回位弹簧的作用下，制动蹄回到原来的位置。当摩擦片磨损，制动蹄与制动鼓之间的间隙变大。如果这个间隙增大到一定程度，自动调节装置就会调节制动蹄的位置，使制动蹄与制动鼓之间的间隙减小。
液压制动系统
当驾驶员踩下制动踏板，制动踏板控制整个液压系统。
典型的制动系统包括以下几个基本组成部分。
(1)主缸：直接与制动踏板连接，将脚的机械压力转换成液压。
(2)制动管路和制动软管：它们将主缸与各车轮的轮缸连接起来。
(3)制动液：这是一种具有特殊性能的油。这种油能够在低温下不凝固，高温下不沸腾。
在制动系统中，主缸分成独立的两部分，每部分里面都有一个活塞，两个活塞都与驾驶室的制动踏板相连，当制动踏板被踩下时，制动液从主缸被送到车轮的轮缸中，车轮的轮缸中，液体推动制动蹄片或制动块阻止制动鼓或制动盘的转动，这样可降低车速
或制动汽车。
汽车制动液的日常保养：通常制动液的维护周期为2年或者4.8万km。关于制动液的推荐维护周期，欧洲汽车制造商笼统地定为几年；而日本和美国的汽车制造商则在其车主手册中一般都有详细的描述。对于具有防抱死abs功能的制动系统，及时地补充制动液就显得尤为重要。这主要是由于其蓄能器中灰尘和湿气的污染会导致价格不菲的阀体发生故障，并由此埋下安全隐患当车主发现汽车制动力衰弱时，可以使用制动液湿度测试纸辅助分析故障原因是否因制动液缺损所致。如果该故障的根源为制动液不足，必须及时补充足量的制动液。由制动液储液罐通风口处正常渗入(或当储液罐盖打开时非正常进入)的湿气和灰尘缩短了制动液的维护周期。在对制动液进行维护的同时，切不可疏忽车轮制动部分。
汽车刹车垫、制动鼓、旋转体及制动钳：当前驱车辆主领潮流时，人们关注的焦点是如何对担当了2/3制动任务的前轮制动系进行科学有效的维护。现在，由于各种后驱车、全驱车、货车和suv遍地开花，人们“重前轻后”的传统观念已经在逐步改变。
逐渐取代石棉衬片的半金属刹车垫将导致旋转体全表面的严重磨损。对汽车车轮制动部件或刹车垫的检查是一项复杂的工作，并不是简简单单地从两边目测一下前轮刹车垫中间点的磨损量。在实际操作过程中，即使制动钳的开口距离恰好能够让您看到两边的刹车垫，也并不等于就可以得心应手、畅通无阻地操作了。此外，由于制动器防护罩的普及应用，使得旋转体与刹车垫的接触面被多重遮挡、难以察看。至于采用盘式制动的后轮，那更是深藏不露，令人难窥其貌。
通常，只有系统出现明显泄漏时，我们才会着重检查制动液的密封性。其全面系统的检查包括传统的静态检查(即原地静态查找泄漏点)和动态检查(即检查制动过程中的密封状况)。无论如何，当车辆制动系维护后续驶里程达到4.8万km时，便需要对车辆的制动系进行一次全面的专业维护。
汽车制动旋转体上的轻微划痕并无大碍。不过由于紧固螺母拧紧力不均和制动旋转体厚度不均而导致旋转体的过度磨损将严重影响制动性能。为了减轻重量，许多旋转体采用了非常规结构尺寸，从而难以满足部分机床加工夹持的基本要求。如果您发现某一旋转体已经过加工，那么请按照同一车轴上第二只旋转体的尺寸对其进行更换。理论上，可以仅更换一只旋转体，但是为了获得最佳的制动平衡效果，还是建议同时更换同一车轴上的两只旋转体。该建议同样也适用汽车在制动过程中，通过感受制动钳活塞的回复运动，便可以完成制动钳关键功能的自动检查工作。如果制动钳活塞回位不顺，请更换一只新的制动钳；如果要泄放或充注制动液，请确认泄放阀可以正常打开；如果泄放阀凝结，请更换为新的制动钳。
如果石棉衬片磨损了3.175mm，此时即使在轻负荷下，其安全驶里程也很有限了。另外，如果需要进行中高负荷的刹车，该磨损衬片弱的制动力将使行车的安全性打折扣。
一些后轮盘式制动的后驱车采用了帽式旋转体，该帽式旋转体还充当了驻车制动鼓。有人忽略取消驻车制动便直接驱动汽车，其旋转体和制动蹄进行直接的金属-金属
摩擦，结果必将导致旋转体、刹车垫和制动蹄发生严重磨损。

摘要 将稳定控制系统应用于差动制动内/外轮胎是现在对客车车辆的标准（电子稳定系统ESP、直接偏航力矩控制DYC）。这些系统假设将两个偏航率(通常是衡量板)和侧滑角作为控制变量。不幸的是后者的具体数值只有通过非常昂贵却不适合用于普通车辆的设备才可以实现直接被测量,因此只能估计其数值。几个州的观察家最终将适应参数的参考车辆模型作为开发的目的。然而侧滑角的估计还是一个悬而未决的问题。为了避免有关参考模型参数识别/适应的问题,本文提出了分层神经网络方法估算侧滑角。横向加速度、偏航角速率、速度和引导角,都可以作为普通传感器的输入值。人脑中的神经网络的设计和定义的策略构成训练集通过数值模拟与七分布式光纤传感器的车辆模型都已经获得了。在各种路面上神经网络性能和稳定已经通过处理实验数据获得和相应的车辆和提到几个处理演习(一步引导、电源、双车道变化等)得以证实。结果通常显示估计和测量的侧滑角之间有良好的一致性。 1 介绍 稳定控制系统可以防止车辆的旋转和漂移。实际上，在轮胎和道路之间的物理极限的附着力下驾驶汽车是一个极其困难的任务。通常大部分司机不能处理这种情况和失去控制的车辆。最近,为了提高车辆安全，稳定控制系统(ESP[1,2]; DYC[3,4])介绍了通过将差动制动/驱动扭矩应用到内/外轮胎来试图控制偏航力矩的方法。 横摆力矩控制系统（DYC）是基于偏航角速率反馈进行控制的。在这种情况下,控制系统使车辆处于由司机转向输入和车辆速度控制的期望的偏航率[3,4]。然而为了确保稳定，防止特别是在低摩擦路面上的车辆侧滑角变得太大是必要的[1,2]。事实上由于非线性回旋力和轮胎滑移角之间的关系，转向角的变化几乎不改变偏航力矩。因此两个偏航率和侧滑角的实现需要一个有效的稳定控制系统[1,2]。不幸的是,能直接测量的侧滑角只能用特殊设备(光学传感器或GPS惯性传感器的组合)，现在这种设备非常昂贵,不适合在普通汽车上实现。因此, 必须在实时测量的基础上进行侧滑角估计，具体是测量横向/纵向加速度、角速度、引导角度和车轮角速度来估计车辆速度。 在主要是基于状态观测器/卡尔曼滤波器(5、6)的文学资料里, 提出了几个侧滑角估计策略。因为国家观察员都基于一个参考车辆模型,他们只有准确已知模型参数的情况下，才可以提供一个令人满意的估计。根据这种观点,轮胎特性尤其关键取决于附着条件、温度、磨损等特点。 轮胎转弯刚度的提出就是为了克服这些困难,适应观察员能够提供一个同步估计的侧滑角和附着条件[7,8]。这种方法的弊端是一个更复杂的布局的估计量导致需要很高的计算工作量。 另一种方法可由代表神经网络由于其承受能力模型非线性系统，这样不需要一个参
附录 附录A Braking system function is to make the car driving in accordance with the requirements of the pilot required even slow down park; They offend car has in various road conditions (including in the slope stability) in car; Make the downhill cars speed to be stable. For car up the role of brake is only in the car and role with the direction of the car driving direction opposite forces, and the size of these forces are random, do not control, so cars must be installed on a series of special equipment to achieve the function. Automobile brake system is to point to to ensure that the car in technology, improve the safe driving car average speed, etc., and the admiration installed in the car brake special brake institutions. In general automobile brake system including crane brake system and parking brake two sets of independent device. One crane brake device is a driver with feet to manipulate, and it said the foot brake. Parking brake device is a pilot with the hand, so it says of the manipulation of the hand brake. The function of the crane brake system is to make the car slow down or running in the shortest distance parking within. And parking brake function is to make had stopped the car on the road all keep still. But, sometimes, in an emergency, two braking device can be used at the same time and increase the effect of auto brake. Some special purpose of cars and often in the mountains cars, long and frequently brake will lead to crane brake system overheating, so in these cars often add all sorts of different types of auxiliary braking equipment, so as to speed up the hill stability. According to the braking energy situation, brake system can also be divided into human brake system, power brake system, and servo brake system, three. Human brake system to the driver's physical strength as braking energy; Power brake system engine power to the transformation of the air pressure or hydraulic braking energy as; And servo brake system is the most human and engine power as a brake energy. In addition, according to the braking energy transfer mode, brake system and can be divided into mechanical and hydraulic, pneumatic type and assolenoid style wait until a few kinds.
The development of automobile As the world energy crisis and the war and the energy consumption of oil -- and are full of energy in one day someday it will disappear without a trace. Oil is not inresources. So in oil consumption must be clean before finding a replacement. With the development of science and technology the progress of the society people invented the electric car. Electric cars will become the most ideal of transportation. In the development of world each aspect is fruitful especially with the automobile electronic technology and computer and rapid development of the information age. The electronic control technology in the car on a wide range of applications the application of the electronic device cars and electronic technology not only to improve and enhance the quality and the traditional automobile electrical performance but also improve the automobile fuel economy performance reliability and emission spurification. Widely used in automobile electronic products not only reduces the cost and reduce the complexity of the maintenance. From the fuel injection engine ignition devices air control and emission control and fault diagnosis to the body auxiliary devices are generally used in electronic control technology auto development mainly electromechanical integration. Widely used in automotive electronic control ignition system mainly electronic control fuel injection system electronic control ignition system electronic control automatic transmission electronic control ABS/ASR control system electronic control suspension system electronic control power steering system vehicle dynamic control system the airbag systems active belt system electronic control system and the automatic air-conditioning and GPS navigation system etc. With the system response the use function of quick car high reliability guarantees of engine power and reduce fuel consumption and emission regulations meet standards. The car is essential to modern traffic tools. And electric cars bring us infinite joy will give us the physical and mental relaxation. Take for example automatic transmission in road can not on the clutch can achieve automatic shift and engine flameout not so effective improve the driving convenience lighten the fatigue strength. Automatic transmission consists mainly of hydraulic torque converter gear transmission pump hydraulic control system electronic control system and oil cooling system etc. The electronic control of suspension is mainly used to cushion the impact of the body and the road to reduce vibration that car getting smooth-going and stability. When the vehicle in the car when the road uneven road can according to automatically adjust the height. When the car ratio of height low set to gas or oil cylinder filling or oil. If is opposite gas or diarrhea. To ensure and improve the level of driving cars driving stability. Variable force power steering system can significantly change the driver for the work efficiency and the state so widely used in electric cars. VDC to vehicle performance has important function it can according to the need of active braking to change the wheels of the car car motions of state and optimum control performance and increased automobile adhesion controlling and stability. Besides these appear beyond 4WS 4WD electric cars can greatly improve the performance of the value and ascending simultaneously. ABS braking distance is reduced and can keep turning skills effectively improve the stability of the directions simultaneously reduce tyre wear. The airbag appear in large programs protected the driver and passengers safety and greatly reduce automobile in collision of drivers and passengers in the buffer to protect the safety of life. Intelligent electronic technology in the bus to promote safe driving and that the other functions. The realization of automatic driving through various sensors. Except some smart cars equipped with multiple outside sensors can fully perception of information and traffic facilities
Automobile Brake System The braking system is the most important system in cars. If the brakes fail, the result can be disastrous. Brakes are actually energy conversion devices, which convert the kinetic energy (momentum) of the vehicle into thermal energy (heat).When stepping on the brakes, the driver commands a stopping force ten times as powerful as the force that puts the car in motion. The braking system can exert thousands of pounds of pressure on each of the four brakes. Two complete independent braking systems are used on the car. They are the service brake and the parking brake. The service brake acts to slow, stop, or hold the vehicle during normal driving. They are foot-operated by the driver depressing and releasing the brake pedal. The primary purpose of the parking brake is to hold the vehicle stationary while it is unattended. The parking brake is mechanically operated by when a separate parking brake foot pedal or hand lever is set. The brake system is composed of the following basic c omponents: the “master cylinder” which is located under the hood, and is directly connected to the brake pedal, converts driver foot’s mechanical pressure into hydraulic pressure. Steel “brake lines” and flexible “brake hoses” connect the master cylinder to the cylinders” located at each wheel. Brake fluid, specially designed to work in extreme conditions, fills the system. “Shoes” and “pads” are pushed by cylinders to contact the “drums” and “rotors” thus causing drag, which (hopefully) slows the car. The typical brake system consists of disk brakes in front and either disk or drum brakes in the rear connected by a system of tubes and hoses that link the brake at each wheel to the master cylinder (Figure).

汽车变速器设计 ----------外文翻译 我们知道，汽车发动机在一定的转速下能够达到最好的状态，此时发出的功率比较大，燃油经济性也比较好。因此，我们希望发动机总是在最好的状态下工作。但是，汽车在使用的时候需要有不同的速度，这样就产生了矛盾。这个矛盾要通过变速器来解决。 汽车变速器的作用用一句话概括，就叫做变速变扭，即增速减扭或减速增扭。为什么减速可以增扭，而增速又要减扭呢？设发动机输出的功率不变，功率可以表示为 N = w T，其中w是转动的角速度，T是扭距。当N固定的时候，w与T是成反比的。所以增速必减扭，减速必增扭。汽车变速器齿轮传动就根据变速变扭的原理，分成各个档位对应不同的传动比，以适应不同的运行状况。 一般的手动变速器内设置输入轴、中间轴和输出轴，又称三轴式，另外还有倒档轴。三轴式是变速器的主体结构，输入轴的转速也就是发动机的转速，输出轴转速则是中间轴与输出轴之间不同齿轮啮合所产生的转速。不同的齿轮啮合就有不同的传动比，也就有了不同的转速。例如郑州日产ZN6481W2G型SUV车手动变速器，它的传动比分别是：1档3.704:１；2档2.202:1；3档1.414:1；4档1:1；5档（超速档）0.802:1。 当汽车启动司机选择1档时，拨叉将1/2档同步器向后接合1档齿轮并将它锁定输出轴上，动力经输入轴、中间轴和输出轴上的1档齿轮，1档齿轮带动输出轴，输出轴将动力传递到传动轴上（红色箭头）。典型1档变速齿轮传动比是3:1,也就是说输入轴转3圈，输出轴转1圈。 当汽车增速司机选择2档时，拨叉将1/2档同步器与1档分离后接合2档齿轮并锁定输出轴上，动力传递路线相似，所不同的是输出轴上的1档齿轮换成2档齿轮带动输出轴。典型2档变速齿轮传动比是2.2:1，输入轴转2.2圈，输出轴转1圈，比1档转速增加，扭矩降低。

The typical brake system consists of disk brakes in front and either disk or drum brakes in the rear connected by a system of tubes and hoses that link the brake at each wheel to the master cylinder (Figure). Basically, all car brakes are friction brakes. When the driver applies the brake, the control device forces brake shoes, or pads, against the rotating brake drum or disks at wheel. Friction between the shoes or pads and the drums or disks then slows or stops the wheel so that the car is braked.
As the world energy crisis, and the war and the energy consumption of oil -- and are full of energy, in one day, someday it will disappear without a trace. Oil is not in resources. So in oil consumption must be clean before finding a replacement. With the development of science and technology the progress of the society, people invented the electric car. Electric cars will become the most ideal of transportation. In the development of world each aspect is fruitful, especially with the automobile electronic technology and computer and rapid development of the information age. The electronic control technology in the car on a wide range of applications, the application of the electronic device, cars, and electronic technology not only to improve and enhance the quality and the traditional automobile electrical performance, but also improve the automobile fuel economy, performance, reliability and emissions purification. Widely used in automobile electronic products not only reduces the cost and reduce the complexity of the maintenance. From the fuel injection engine ignition devices, air control and emission control and fault diagnosis to the body auxiliary devices are generally used in electronic control technology, auto development mainly electromechanical integration. Widely used in automotive electronic control ignition system mainly electronic control fuel injection system, electronic control ignition system, electronic control automatic transmission, electronic control (ABS/ASR) control system, electronic control suspension system, electronic control power steering system, vehicle dynamic control system, the airbag systems, active belt system, electronic control system and the automatic air-conditioning and GPS navigation system etc. With the system response, the use function of quick car, high reliability, guarantees of engine power and reduce fuel consumption and emission regulations meet standards. The car is essential to modern traffic tools. And electric cars bring us infinite joy will give us the physical and mental relaxation. Take for example, automatic transmission in road, can not on the clutch, can achieve automatic shift and engine flameout, not so effective improve the driving convenience lighten the fatigue strength. Automatic transmission consists mainly of hydraulic torque converter, gear transmission, pump, hydraulic control system, electronic control system and oil cooling system, etc. The electronic control of suspension is mainly used to cushion the impact of the body and the road to reduce vibration that car getting smooth-going and
