電動車両の回生ブレーキ制御特性を考慮したペダル操作用運転ロボットの構築

抄録

A Real Driving Emission (RDE) test procedure for type approval was started in Japan in 2022. In Japan, test vehicle is driven on a test road (test course) by tracing a speed pattern prepared per RDE test. In the test, the vehicle has need to trace the patterns in the same manner as the conventional chassis dynamometer test. To trace the target vehicle speed at these tests precisely, the use of a driving robot is effective for reproducibility. In this study, we developed the driving robot for the electrified vehicles (HEV, Plug-in HEV, BEV, FCV), which have the regenerative brake control. We applied a new logic to our self-product robot for the engine vehicles. To change the operation timing from the accelerator pedal to the brake pedal, we focused the braking deceleration of the regenerative brake control. At the chassis dynamometer and the test road, we verified the improvement of the speed traceability by the driving robot installed this logic.
