摘要： [Object]The present invention provides a suspension control apparatus that allows miniaturization of a solenoid valve.[Solution]When a controller is started up by a power source controller (a power source unit), the controller switches a control current from 0 ampere to a maximum current value I6 at the same time as the startup. After that, the control shifts to normal control. As a result, even if a hysteresis of a damping force characteristic is large relative to the control current, it is possible to promptly move a solenoid valve to a position to be used in the normal control.

摘要： A vehicle attitude controller capable of improving turning operability, steering stability, and ride quality of a vehicle. In a normal-operation region, a pitch control unit for calculating a target pitch rate in accordance with a roll rate performs control in priority to a roll suppression section. In this case, a target damping force calculated in the pitch control unit is weighed to control a damping-force characteristic of the dampers so that a pitch rate becomes equal to the target pitch rate. In a critical region in which a road-surface gripping state of the vehicle tires is bad, the roll suppression section performs control in priority to the pitch control unit so as to weigh a target damping force calculated in the roll suppression section. As a result, the damping-force characteristic of the dampers is controlled so as to increase the amount of roll suppression control.

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 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.

摘要： In a suspension control system 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.
