Realtime SMART Speed Pattern Generator for EVs taking account of driver's command change

Abstract

Electric Vehicles (EVs) driven by electric motors are suitable for speed control, which means the ride comfort and safety can be improved in ordinary traveling and emergency by applying speed patterns. The main contribution of this paper is the development of a Realtime SMART Speed Pattern Generator (RSSPG) taking account of driver's command change. In the RSSPG, speedy acceleration/deceleration can be implemented under the constraints of acceleration and jerk limits. The parameter C which is associated with slope of jerk can be adjusted to fit accelerator/brake actions of human drivers with different driving styles. Some experimental results by our test EV 'UOT March II' are shown to verify the effectiveness of the proposed RSSPG. © 2007 WEVA Journal.
