This paper proposes a regenerative baking control system of handle-type electric wheelchairs for senior citizen. "Electric wheelchair", which generates the driving force by electric motors according to the human operation, is expected to be widely used as a mobility support system for elderly people. This study focuses on the braking control to realize the safety and smooth stopping motion using the regenerative braking control technique based on fuzzy inference. The ride quality improvement and energy recycling can be expected by the proposed control system with stopping distance estimation and variable duty ratio control on the step-up chopper regenerative circuit. Driving experimental results are provided to verify the effectiveness of the proposed control system.
