    摘要: A brake apparatus for an electric automobile applies brakes to the vehicle to achieve a required amount of braking force by combining regenerative braking force of an electric motor with mechanical braking force produced by a mechanical braking system. The braking force required by a driver is obtained from the depression force applied to a brake pedal, and the maximum regenerative braking force, that can be generated by the motor, is obtained from the rotation speed of the motor. The target mechanical braking force is calculated based on the required braking force and the maximum regenerative braking force. By suitably controlling the pneumatic pressure applied to a booster device provided in the mechanical brake system, the fluid pressure actually applied to brake actuating members is controlled to provide the target mechanical braking force.
