Patent ID: 7289897

Claim:
A brake device comprising: an actuator which is provided on an unspring-mass wheel side of a vehicle having a suspension and which is adapted to generate a braking force by being electrically driven; a drive controller to receive a signal regarding the braking force from a vehicle motion controller and to drive said actuator, wherein said vehicle motion controller is located at a spring-mass vehicle body side of said vehicle, a sensor device to detect operating values of said actuator and to provide said operating values to said drive controller, said sensor device being disposed at the unspring-mass wheel side of the vehicle, and a signal line connecting said drive controller and said vehicle motion controller, said signal line being adapted to communicate between said drive controller and said vehicle motion controller in bidirectional multiplex communication, wherein said drive controller is located at the unspring-mass wheel side of the vehicle, wherein said drive controller is adapted to send a signal to a spring-mass vehicle body side of said vehicle and to receive a signal from said spring-mass vehicle body side of said vehicle, and wherein, in a portion connecting the spring-mass vehicle body side and the unspring-mass wheel side, said signal line and a power line supplying electric power to said drive controller are connected by a single cable covered with a same sheath.
