IntroductionWith the rapid development of science and technology, intelligent vehicles have become a hot topic in the field of automotive engineering. Intelligent vehicles are designed to improve road safety, reduce congestion, and enhance thedriving experience. They are equipped with sensors and communication devices that allow them to interact with the environment and other vehicles. Moreover, they can perform various tasks autonomously, such as obstacle avoidance, lanedetection, and traffic signal recognition. This paperpresents the design and implementation of a multi-functional intelligent vehicle based on the 89C51 microcontroller.2. System ArchitectureThe intelligent vehicle comprises a 89C51 microcontroller, various sensors, actuators, and a wireless communication module. The microcontroller acts as the brainof the vehicle, controlling the movement of the DC motors and processing the data from the sensors. The sensors used inthis design include infrared sensors, ultrasonic sensors, and line tracking sensors. The infrared sensors are used todetect obstacles in front of the vehicle, while theultrasonic sensors are used to detect obstacles in a wider range. The line tracking sensors are used to follow the black line on the ground. The DC motors are responsible for the movement of the vehicle, and they are controlled by a motor driver circuit based on the 89C51 microcontroller.The wireless communication module is used to control the vehicle remotely. It is based on the ZigBee protocol, whichis a low-power, low-data-rate wireless communication protocol. The system uses two ZigBee modules, one connected to the microcontroller on the vehicle, and the other connected to a remote control device. The remote control device sends commands to the vehicle via the wireless communication module, enabling the vehicle to be controlled remotely.3. System DesignThe main objective of the system design is to enable the vehicle to perform various tasks autonomously. The system is designed to detect obstacles, follow a black line on the ground, and perform different maneuvers based on varying road conditions. The main components of the system are describedbelow.3.1 Obstacle DetectionThe vehicle uses infrared sensors and ultrasonic sensors to detect obstacles in its path. The infrared sensors are mounted on the front of the vehicle and are used to detect obstacles in a narrow range. The ultrasonic sensors are mounted on the sides of the vehicle and are used to detect obstacles in a wider range. The sensor data is processed by the microcontroller, which determines the presence and location of obstacles. The vehicle then takes appropriate action, such as stopping or changing direction, to avoid the obstacle.3.2 Line FollowingThe vehicle uses line tracking sensors to follow a black line on the ground. The sensors are mounted underneath the vehicle and are used to detect the position of the line. The sensor data is processed by the microcontroller, which determines the direction and speed of the vehicle. Thevehicle then adjusts its movement to follow the line.3.3 ManeuversThe vehicle is capable of performing different maneuvers based on varying road conditions. For example, it can perform a U-turn if it encounters an obstacle in its path or if it loses track of the line. It can also adjust its speed based on the distance to an obstacle or the curvature of the line.4. Experimental ResultsThe proposed design was implemented and tested in a laboratory setting. The vehicle was able to detect obstacles in its path, follow a black line on the ground, and perform different maneuvers based on varying road conditions. The wireless communication module allowed the vehicle to becontrolled remotely, enabling it to perform different tasks from a distance. The results demonstrate that the proposed design is effective and efficient in performing various tasks autonomously.5.
