    摘要： An electronic controlled fluid suspension system in which a change in a vehicle attitude is expected in advance by an advance control means responsive to a driving state detected by a driving state detection means, and the current vehicle attitude is feedback-controlled by a feedback control means. The shares of the advance control amount and the feedback control amount are calculated by a share determination means so that final control amount is determined based on the shares. Fluid flow to and from the fluid suspension is controlled by a fluid flow control means in response to the final control amount. In such control system, the advance control and the feedback control are smoothly switched, which results in improved maneuverability and stability of the vehicle.

    摘要： An air pressure circuit comprising a compressor (3) cylinder which is divided into two chambers by a slidable piston, a suction (1) port and an exhaust port (2), each having a valve and mounted on one chamber of the cylinder, inhaling air of a pressure higher than that of atmospheric air from the suction port and exhausting the piston-compressed air from the exhaust port. The air pressure in the side of suction port is introduced to the other chamber (3a) of the cylinder.

    摘要： In controlling roll and pitch of a vehicle body responsive to a displacement signal produced at each wheel of the vehicle, each signal is low-pass- filtered with a certain threshold frequency to prevent hunting of the control due to an excessively high frequency component (such as noise or a component corresponding to road irregularities) of the signal. According to this invention, the threshold frequency is changed to a higher value in order to get quick attitude control when the roll or pitch of the body is expected, while it is set at a lower value when no such attitude change is expected in order to prevent hunting of the control.

    摘要： In an electric control apparatus (C) for a four-wheel steering system including an electric motor (56) the rotary angle of which is electrically controlled in accordance with a target steering angle of rear road wheels (RW1, RW2), and a hydro-mechanical tracer mechanism having a fluid control valve (36) the valve element of which is drivingly connected to the electric motor (56) to be displaced in proportion to the rotary angle of the electric motor (56), the tracer mechanism being arranged to steer the rear road wheels (RW1),(RW2)in proportion to a displacement amount of the valve element, the target steering angle is converted into a control value for rotation of the electric motor (56), and a drive signal indicative of the control value is applied to the electric motor (56). The electric control apparatus (C) is designed to greatly change the control value to and from zero when the target steering angle is less than a predetermined small angle approximately zero and to change the control valve in proportion to the target steering angle when the target steering angle is more than the predetermined small angle.
