  • Patent number: 7289897
    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).

  • Patent number: 7136736
    Abstract: In a vehicular control device, it is necessary to measure or calculate six physical quantities-forward-reverse speed, left-right speed, vertical speed, pitch angle, roll angle, and angle of sideslip-representing vehicular movement and to control the braking force of each wheel and/or the damping coefficient of each suspension shock absorber in order to further shorten braking distance particularly at the time of braking and to prevent spin at that time. In this case, it is necessary to furnish sensors to measure speed and angle directly. In the present invention, four radar sensors are used in order to directly measure the forward-reverse speed and the left-right speed. Also, the vertical speed, the pitch angle, the roll angle, and the angle of sideslip are indirectly measured from the output of the radar sensors.

  • Patent number: 6728614
    Abstract: A power supply system for a vehicle is provided which is able to supply an electric brake apparatus with necessary power even if an abnormal condition occurs in a battery or a conductor which is connected to the electric brake apparatus. A relay control unit 12 normally brings a relay 11 in a state in which its input terminal is connected to an A terminal 13. This causes a generator 50 or main battery 20 to supply an electric brake apparatus 100 with power via first and second power supply lines 40 and 41 and charges an auxiliary battery 21. If an abnormal condition occurs at main and auxiliary batteries 20 and 21, main and auxiliary power supply lines 30 and 31, first and second power supply lines 40 and 41, the relay control unit 12 brings the relay 21 into a state in which its input terminal is connected to A or B terminal 13 or 14 in response to the abnormal condition.
