Abstract
A braking control system for an electric automobile combines the use of mechanical braking and regenerative braking by a motor. Namely, a braking control system for the electrical automobile, which permits the combined use of regenerative braking and mechanical braking, is provided with target braking force setting unit (9) for setting a target braking force on the basis of a brake pedal stroke, regeneration control system (4A,5A) for setting a target regenerative braking force on the basis of the brake pedal stroke and then controlling regenerative braking by the motor in accordance with the target regenerative braking force, and mechanical braking control unit (24) for controlling operation of a mechanical brake system (B) in accordance with a difference between said target braking force and an actual braking force determined based on a detected deceleration of a vehicle. These features make it possible to surely obtain a desired braking force and also to promote the recovery of energy by regenerative braking.
