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).

In a power steering system comprising a power cylinder for assisting a steering power of a steering mechanism, a hydraulic pump for supplying a hydraulic pressure to the power cylinder, a first oil passage and a second oil passage connecting the power cylinder and the hydraulic pump respectively, a motor for driving the hydraulic pump, and power steering control means for calculating a command value to the motor based on the steering torque, a flow rate of the working oil supplied from a high-pressure side oil passage to a low-pressure side oil passage is restrained at the transition from the end of the steering state (lock end) of the steering mechanism to the returning. The flow-rate restraint increasingly corrects a driving current of the motor in the steering direction or limits the flow rate of the working oil.
