Automatic driving system by small electric vehicle for elderly person

This paper describes the automatic driving control system for elderly person using low cost sensors. Firstly, the small automatic electric vehicle and the control devices are explained. Next, the path tracking method is explained. And in order to realize path tracking, GPS and IMU are used to calculate the current position and orientation separately in real time for steering angle control. By the fusion method of Ultrasonic sensors, CCD stereo camera, GPS and IMU, the automatic driving system and the obstacle avoiding system is realized. Some test runs of automatic driving system of a small vehicle was done to verify the fusion and control methods in the outdoor experiments.
