摘要： In an active vehicle suspension system employing a double acting type single rod hydraulic linear actuator in which a piston is provided with two pressure receiving surfaces facing two different piston chambers defined by the piston received in a cylinder and having different areas, even when the line pressure of the hydraulic oil passage is lost, the height of the vehicle body can be maintained at a fixed level and a sudden change of the height of the vehicle body can be avoided by providing a hydraulic control device which appropriately controls the pressures of the upper and lower chambers so as to be inversely proportional to the areas of the corresponding pressure receiving surfaces as the pressure supplied to the hydraulic actuator is reduced.

摘要： A hydraulic control device for an active suspension system employing a linear hydraulic cylinder including a piston connected in parallel with a spring between a wheel and a vehicle body, the piston having two pressure receiving surfaces of different areas facing two chambers separated by the piston in the cylinder, comprising a balancing valve for reducing the pressures of the two chambers to a level near the atmospheric pressure, a switch valve provided in a bypass passage between the two chambers for selectively communicating the two chambers with each other, a flow restricting orifice provided in the bypass passage; and an accumulator connected to the bypass passage capable of accommodating a change in the capacity of one of the chambers due to a piston rod extending from the piston out of the cylinder when the pressures of the two chambers are at the level near the atmospheric pressure. Alternatively, the accumulator could be replaced with a storage container connected to the bypass passage capable of accommodating an amount of actuating oil corresponding to a capacity of the cylinder. Thus, the active suspension system can serve as a workable passive suspension system when the supply of hydraulic oil is interrupted for any reason, and the reliability of the system can be improved.

摘要： In an hydraulic active vehicle suspension system using a linear hydraulic cylinder as a primary actuator, controlled hydraulic pressure is supplied to an upper chamber of the hydraulic cylinder defined by a smaller pressure receiving surface of the piston and the cylinder while a reduced and fixed pressure is supplied to a lower chamber of the hydraulic cylinder defined by a larger pressure receiving surface of the piston and the cylinder, and an accumulator is connected to the lower chamber so that a desired hydraulic actuation can be accomplished by the controlled hydraulic pressure while sudden forces or inputs containing high frequency components applied to the lower chamber are absorbed by the accumulator. Thus, the accumulator offers a favorable response to the wheel riding over a bump or otherwise experiencing sudden movements and the absence of any accumulator connected to the upper chamber ensures a high speed response property of the system without requiring a large power capacity of the pump serving as the pressure source for the system.

摘要： In a vehicle suspension system including a hydraulic actuator between a sprung mass consisting substantially of a vehicle body and an unsprung mass consisting substantially of a wheel, a force proportional to but opposite in phase to an inertia force acting on the unsprung mass is applied by the actuator to the unsprung mass so that the ability of the tire to maintain contact with the road surface may be improved. This produces very little effect on the behavior of the sprung mass, but the vehicle handling is significantly improved. Better contact with the road surface not only improves the vehicle handling but also reduces the consumption of energy by the hydraulic actuator. A particularly favorable result can be obtained when the hydraulic actuator further applies a damping force proportional to the absolute velocity of the sprung mass to the sprung mass.

摘要： In an active vehicle suspension system employing a spring and a hydraulic actuator for supporting a wheel relative to a vehicle body, a control unit actuates the actuator so as to cancel the force applied by the spring force of the spring and a damping force applied by the hydraulic actuator. This damping force is typically produced by the flow resistance which the hydraulic oil encounters in the hydraulic circuit. This control action is carried out according to a signal obtained by processing an output of a displacement sensor between the wheel and the vehicle body with a first-order lead filter circuit. Thus, the control action is based on a readily available and highly responsive detection signal, an accurate and stable vibration control of the sprung mass of the vehicle or the vehicle body is made possible. This control action may be combined with a conventional feedback control based on the acceleration of the sprung mass or the load acting between the suspension system and the vehicle body, and a low-pass filter which ensures the stability of the system even when the first-order lead filter circuit is used.

摘要： A feed-forward control section controls, in a feed-forward manner, left and right hydraulic clutches C.sub.L and C.sub.R of a driving force distributing device by presuming such a driving force distribution amount .DELTA.T that a yaw rate corresponding to a turning state of a vehicle is obtained, based on an engine torque, an engine revolution-number, a vehicle speed, a steering angle and a lateral acceleration. On the other hand, a feedback control section calculates a deviation between a reference yaw rate calculated from the vehicle speed and the lateral acceleration and an actual yaw rate detected by a yaw rate sensor, and corrects the driving force distribution amount .DELTA.T calculating in the driving force distributing device in order to converge the deviation into zero. Therefore, even if the driving force distribution amount becomes excessive due to the feed-forward control to produce an over-steering tendency in the vehicle, this over-steering tendency can be eliminated by the feedback control to stabilize the behavior of the vehicle.

摘要： An active engine mount system for supporting an engine on a vehicle body is used for controlling the vertical movement of the vehicle body produced by irregularities of the road surface. The engine mount system comprises an actuator interposed between the engine and the vehicle body for applying a vertical force to the vehicle body so that the vertical acceleration of the vehicle body for each given condition of the road surface may be minimized by adjusting a contribution of the mass of the engine to the mass of the vehicle body. The engine mount system may consist of a full active or semi active mount system. By detecting the road condition ahead of the vehicle, a particularly favorable result can be achieved.
