Abstract:
In a vehicle capable of performing regenerative braking and fluid pressure braking, in changing from the regenerative braking to the fluid pressure braking in response to a decrease of a vehicle speed due to braking, a fluid pressure braking force is increased from 0 at a first increasing rate when the vehicle speed falls to or below a first threshold value (V1), and the fluid pressure braking force is increased at a second increasing rate, which is higher than the first increasing rate, when the vehicle speed falls to or below a second threshold value (V2), which is smaller than the first threshold value (V1). With this configuration, while occurrence of a squeal noise of a wheel cylinder can be prevented by setting the first increasing rate of the fluid pressure braking force at a small value, a required braking force can be generated without any problem by setting the second increasing rate, to be used subsequently thereto, of the fluid pressure braking force at a large value.
