PROBLEM TO BE SOLVED: To provide a regenerative brake system which can avoid deterioration of brake feeling in the state that oscillation of fluid pressure is generated. SOLUTION: A regenerative ECU 17 performs determination whether the car is running in a good state or bad state based on sensed outputs of wheel acceleration sensors 33, 34, 35, 36. Under the good state running, hydraulic braking is controlled cooperatively with regenerative braking due to a motor 11. Under the bad state running, a motor ECU 15 and the regenerative ECU 17 gradually control the regenerative braking, finally prohibit it, and allow the hydraulic braking alone. |
