<p>An electric brake system for a motor vehicle has a plurality of braking force generating mechanisms 14FL, 14FR, 14RL, 14RR associated with respective road wheels and including electronic actuators 16 mechanically separate from a brake pedal 11. In the event of a failure of at least one of the braking force generating mechanisms, the electric brake system selects and operates the normal braking force generating mechanism or mechanisms for braking the motor vehicle stably with boosted braking forces. The braking force generating mechanisms 14FL, 14FR, 14RL, 14RR are mechanically separate from the brake pedal 11 and operable independently of each other. Failure detecting circuits 19 are associated respectively with the braking force generating mechanisms, for detecting a failure of the braking force generating mechanisms and producing a failure signal representing the failure. The electric brake system includes a controller 13 for controlling said braking force generating mechanisms in response to the signal from the brake pedal 11. The controller selects at least one of said braking force generating mechanisms 14FL, 14FR, 14RL, 14RR to be operated based on the failure signal from the failure detecting circuit according to a predetermined rule. <IMAGE></p> |
