59 Validation of Cooperative Regenerative Braking Control Algorithm Using Hardware In-The-Loop Simulation for ESC

Recently driven by the increase in resource depletion problem and environmental pollution problem, there are active on-going developments of vehicles using motor as power source like hybrid vehicle, electric vehicle, fuel cell vehicle. Regarding such motor-powered vehicles, various researches are in progress for the enhancement of vehicle efficiency, and one essential technique to enhance vehicle fuel efficiency is the regenerative braking that uses the kinetic energy which is consumed as friction upon braking as power source by storing it in energy storage device like battery and ultra capacitor. In the meantime, recently auto market is seeing development of various techniques considering passenger safety as well as fuel efficiency and power performance. Major examples include ABS(Anti-lock Brake System), TCS(Traction Control System), VDC(Vehicle Dynamics Control) and ASC (Active Steering Control) etc. However, as for the existing control logic for regenerative braking, the logic is focused on the improvement of efficiency for such vehicle only in the development, and thus it involves the shortcoming that researches on the acquisition of vehicle safety or driver's maneuvering convenience fall short. Therefore the active safety device of vehicle proposed in this study was intended to solve the challenge to improve vehicle efficiency and the problem of acquiring safety simultaneously by composing the HILS(hardware in-the-loop simulation) of ABS and developing the logic for the cooperative control of ABS and regenerative braking with the use of it.
