Abstract
In an electrically operated vehicle in which a regenerative braking operation is performed to apply a regenerative braking torque to a wheel, if the regenerative braking torque reaches its maximum value and is insufficient to brake the wheel, a static hydraulic pressure outputted from a master cylinder is supplied to the wheel brake cylinder mounted on the wheel until the brake pedal reaches a retained position. Thereafter, a dynamic hydraulic pressure is supplied to the wheel brake cylinder. While the brake pedal is in movement from the rest position to the retained position, the wheel brake cylinder is supplied with only the static hydraulic pressure and while the brake pedal is being retained at the retained position the wheel brake cylinder is supplied with the static hydraulic pressure and the dynamic hydraulic pressure.
