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.

Abstract: The solenoid current increases at low temperatures and decreases at high temperatures because the modulus of elasticity of an elastically deformable valve body and the slide resistance of an elastically deformable seal member vary with temperatures. Therefore the solenoid current for opening the valve mechanism from a closed position is required to be changed with low and high temperatures. To supply the solenoid current necessary for opening the valve mechanism without directly measuring the temperature, the solenoid current (the boost starting current leaning value) indicated when the pressure varies with the opening of the valve mechanism is recorded at the time of pressure-increasing, and thereafter when the valve mechanism is opened again after the closing of the valve mechanism, the solenoid current computed on the basis of the pressure-increase starting current learning value thus recorded is supplied.
