【摘要】四轮独立驱动技术可使电动汽车底盘实现电子化，主动化，大大提高电动汽车的性能。电动汽车四轮独立驱动系统是利用四个独立控制的电动机分别驱动汽车的四个车轮，车轮之间没有机械传动环节。四轮驱动技术比传统驱动技术更有明显的的优势，此技术将来会更有力的运用。为了更进一步了解全时四轮驱动技术，逐一的把四驱技术和传统驱动优缺点对比：

1.传动系统得到减化，整车质量大大减轻。由电动机直接驱动车轮甚至两者集成为一体。

2.与传统汽车相比，四轮独立驱动系统可通过电动机来完成驱动力的控制而不需要其他附件，容易实现性能更好的、成本更低的牵引力控制系统（TCS）、防抱死制动系统（ABS）及动力学控制系统（VDC）。

3.对各车轮采用制动能量回收系统，则可大大提高汽车能量利用效率，且与采用单电动机驱动的电动汽车相比，其能量回收效率也获得显著增加。这对提高电动汽车续驶里程是很重要的。

4.实现汽车底盘系统的电子化、主动化。

Auto four-wheel drive technology

【Abstract】 Four-wheel independent drive technology can make the electric automobile

chassis realization of e-government, active, greatly improving the performance of the electric

vehicle. Electric vehicle four-wheel independent drive system is by four independent control of

motor respectively drive the car four wheels, no mechanical transmission links between the

wheels. Four-wheel drive technology than traditional drive technology is more obvious

advantages, this technology in the future will be more powerful application. To further

understand full-time four-wheel drive technology, each of the raider technology and traditional

drive advantages and disadvantages compared:

1. The transmission systems have simplify, complete quality greatly relieved. Directly driven

by motor wheels or are even integrated into one.

Compared with the traditional automobile 2, four-wheel independent drive system can be

accomplished by motor driving control and do not need other attachments, easy to achieve

better performance, cost lower traction control system (TCS), ABS (ABS) and dynamic control

system (VDC).

3. For each wheel adopts braking energy recovery system, it can greatly improve the car energy

utilization efficiency, and by a single motor drives electric vehicle compared to the energy

recovery efficiency also obtain increased significantly. To improve the electric car onward

travel distance is very important.

4. Realize automobile chassis system of electronic, active glycosylated. Hyundai motor drive system

arrangement is divided into front drive, after driving or whole driver.
