Active safety system for personal mobility vehicles

In this research, an active safety system for personal mobility vehicle is developed. The active safety system includes automatic braking and steering. A mass production electric wheelchair is remodeled to implement control functions. The automatic braking and steering logic are derived from field vehicle test data. Monitoring the distance to the obstacle and the vehicle speed, the collision hazard is evaluated. According to the safety status, the active safety system enhances the collision safety by audible warning and automatic braking or steering. Results of field test demonstrate the performance of active safety system.
