ELECTRIC BRAKE DEVICE

WIPO Patent Application WO/2006/038309

A1

There has been a problem that a vehicle cannot be stopped or parked because of braking force by tires being not available when a parking brake lock mechanism or an electric brake mechanism fails. To solve such a problem, an electric brake device with a parking brake mechanism is constructed such that, when the parking brake lock mechanism or an electric brake mechanism fails, braking force can be maintained by putting a transmission of a vehicle into a connected state, or by controlling the direction of the tire (toe angle) of each wheel independently, or by applying regenerative brake or reverse torque by a motor generator. More specifically, when the parking brake lock mechanism or the electric brake mechanism fails, braking force required for stopping or parking the vehicle can be achieved by putting the transmission into a connected state or controlling the toe angle of the tire independently to produce resistance in a driving system and rolling resistance of tires, or by regenerative brake or reverse torque produced by the motor generator.
