提出了一种基于再生制动系统和驱动控制模式切换的电动助力轮椅车安全驱动控制方案。通过电动机辅助驱动力的“电动助力轮椅”有望作为老年人和残疾人的行动支持系统而广泛使用，然而，它没有制动系统来降低轮椅的速度，并且在下坡路上带来危险和可怕的驾驶。提出了一种基于再生制动和驾驶模式切换的新型安全驾驶控制方案。该系统采用变占空比的再生制动系统，当轮椅在下坡道路上速度增加时，通过从“驱动模式”切换到“制动模式”来实现。实际道路上的行驶试验验证了该控制系统的有效性。
This paper describes a novel safety driving control scheme for electric power assisted wheelchairs based on regenerative braking system and the driving control mode switching. "Electric power assisted wheelchair" which assists the driving force by electric motor is expected to be widely used as a mobility support system for elderly people and disabled people, however, it has no braking system to decrease the wheelchair's velocity and brings the dangerous and fearful driving on downhill roads. This paper proposes a novel safety driving control scheme based on regenerative brake and driving mode switching. This system applies the regenerative braking system with variable duty ratio by switching from "driving mode" to "braking mode" when the wheelchair's velocity increases on downhill roads. Some driving experiments on the practical roads show the effectiveness of the proposed control system.
