Abstract
A brake device includes an actuator which is provided on a wheel side of a vehicle having a suspension, the actuator generates a braking force by being electrically driven. A drive controller is also provided for receiving a signal regarding the braking force from a vehicle motion controller and sensors, and driving the actuator accordingly. To reduce the number of high cost bending wires necessary to communicate between the sensors, the drive controller and the vehicle motion controller, the drive controller and the sensors are attached to the actuator side (unspring-mass) and the drive controllercommunicates with the vehicle motion controller provided on the vehicle body side (spring-mass) of the vehicle by bidirectional multiplex communication.
