ELECTRIC BRAKE SYSTEM

摘要

Provided is an electric brake system which is capable of stopping a vehicle at the will of a driver, even if one brake device among left and right brake devices is in a failed state. The electric brake system is provided with: at least one pair of brake devices which are provided to the left and right sides of a vehicle, are configured so as to propel pistons for pressing, against rotational members that rotate in conjunction with wheels, frictional members, and are configured such that the frictional members are pressed against the rotational members by electric mechanisms in accordance with braking request signals, and the pressing force of the frictional members is maintained; and a control device which controls the respective electric mechanisms of the brake devices, and diagnoses a failed state, i.e. a state in which an abnormality has occurred, in the respective brake devices corresponding to the braking request signals. The control device is configured such that, when it is diagnosed that one brake device among the left and right brake devices is in a failed state, operation of the one brake device by the electric mechanism is prohibited during travel.
