摘要： Shock absorbers of left and right front wheel suspensions and shock absorbers of left and right rear wheel suspensions each are constituted by a damping force adjustable hydraulic shock absorber provided with a frequency response unit. An actuator of a damping force variable mechanism provided to the shock absorber is driven and controlled by a controller. The controller variably adjusts the damping force between the soft side and the hard side by the damping force variable mechanism according to a vertical vibration when a vehicle body vertically vibrates at a low frequency. The controller does not adjust the damping force when the vehicle body vibrates at a higher frequency than the low frequency.

摘要： By passing the vertical acceleration through a phase adjusting filter and a gain adjusting filter, the phase of the vertical acceleration is advanced by 49 degrees so that the phase difference with respect to the actual relative velocity becomes 180 degrees in the neighborhood of the vehicle body resonance point, thereby making the phase of the vertical acceleration, in effect, coincident with the phase of the relative velocity. In the neighborhood of the vehicle body resonance point (1 Hz), the gain of the estimated relative velocity takes a small value. In frequency regions other than the neighborhood of the vehicle body resonance point, the gain of the estimated relative velocity is increased. Consequently, the controlled variable in the neighborhood of the vehicle body resonance point increases, and the controlled variable in higher frequency regions decreases. Damping force is adjusted in correspondence to the controlled variable. Thus, it is possible to improve ride quality in the neighborhood of the vehicle body resonance point (1 Hz).

摘要： In the suspension control apparatus of the present invention, when a lateral acceleration differential value falls outside a lateral acceleration differential value range, a controller calculates a control input for an actuator, based on the lateral acceleration differential value, in preference to a lateral acceleration. Therefore, immediately after the start of rolling of a vehicle and just prior to the end of the rolling when the lateral acceleration differential value falls outside the lateral acceleration differential value range, the control input for the actuator is calculated based on the lateral acceleration differential value. By this arrangement, it is possible to suppress any uncomfortable sensation which is likely to be transmitted to an occupant of the vehicle immediately after the start of rolling and just prior to the end of rolling in a conventional technique, in which the control input for the actuator is calculated by adding the control input varying in proportion to the lateral acceleration and the control input varying in proportion to the lateral acceleration differential value.

摘要： In a suspension control system according to the present invention, a sky-hook command signal B obtained from velocity data obtained by integrating a sprung mass acceleration αu from a sprung mass acceleration sensor 9u and an unsprung mass vibration damping command signal C obtained on the basis of an unsprung mass acceleration αd detected by an unsprung mass acceleration sensor 9d are added together to obtain a control signal A for a damping characteristic inverting type shock absorber 6. The control signal A reflects the unsprung mass acceleration αd that leads in phase by 90° the piston speed. Accordingly, it is possible to compensate for a response delay due to an actuator 11, etc.

摘要： In a suspension control system, a controller previously stores damping force maps (an ordinary road map, a rough road map, and an extremely rough road map) corresponding to road surface conditions (an ordinary road, a rough road, and an extremely rough road) defined by frequency and amplitude of vertical acceleration. The frequency and amplitude of the vertical acceleration are detected, and a damping force map (the ordinary road map, the rough road map, or the extremely rough road map) corresponding to the detected information is selected. Damping force control is effected on the basis of the selected damping force map. Selection of a damping force map according to the frequency and amplitude of the vertical acceleration is also made when a change in the vertical acceleration, i.e. a change in piston speed, is predicted during running on an ordinary road, a rough road or an extremely rough road.
