Abstract
When a brake ECU is started up rapidly by a brake pedal operation, the brake ECU executes a depression force fluid pressure mode. When the control pressure detected by a control pressure sensor becomes smaller than a switching determination threshold value, the brake ECU determines that an operation of returning a brake pedal is being performed, and switches the braking mode from the depression force fluid pressure mode to a normal control mode. Accordingly, even when the operation of a stroke simulator has been started, no uncomfortable feeling is given to a driver. Further, even when the operation of returning the brake pedal is not being performed, the braking mode is switched from the depression force fluid pressure mode to a simulator non-operation control fluid pressure mode when a vehicle starts to travel. Consequently, desired braking force can be rapidly generated.
