Recently, researches about the eco friendly vehicles such as hybrid electric vehicle, fuel cell vehicle and electric vehicle have been actively carried out. The regenerative braking system is a key technology to improve the vehicle energy utilization efficiency because it transforms the kinetic energy to the electric energy through the electric motor. This new braking system requires cooperative control between electric controlled brake and regenerative brake. Therefore, it is necessary to establish fault diagnosis and fail safe evaluation criteria to secure reliability of the regenerative braking system. In this paper, the failure types and causes in regenerative braking system were analyzed. The transient behavior characteristics were examined based on faultdiagnosis and fail safe upon failure of regenerative braking system.

Nowadays researches about the Eco-friendly vehicle, hybrid electric vehicle, fuel cell vehicle and electric vehicle are under active proceeding. Since most of the new energy vehicle has a motor, the regenerative braking system can be used to improve the vehicle energy utilization efficiency. The regenerative braking system can transform the kinetic energy to the electric energy through the motor in the regenerative braking. This technology played a significant role in achieving the high energy usage. When using EMB, cooperative control with regenerative brake system is necessary and the solution how to respond to EMB’s failure has to be made clear. In this paper analyzes some classification and causes of fail of regenerative brake system for fuel-cell vehicle with EMB and researches analyzing method by adding inverter model to EV simulator for fault diagnosis. In addition this paper investigates the behavior of the vehicle based on Fault diagnosis and fail safe when EMB failure occurs in running.
