The project is an electronic driver in a traffic situation. The car being used is equipped with front-mounted ultrasonic sensors to detect distance of other cars. This information is sent to the data-acquisition board and into the computer. Data from the sensors will determine whether the car will accelerate, decelerate, steer, or come to a full stop via dc motors coupled to the accelerator, brake, clutch, and steering mechanisms. Feedback mechanisms using stepper motors as shaft-encoders are used to monitor the motors positions. A high-level language was used in the creation of the accompanying software. The system will opt to follow the car in front, and will steer depending on how close the cars to the sides are. If both sides are too close to the car, the system will activate the brakes to a full stop. This condition also occurs when the car in front is too close.
