摘要： PURPOSE:To rapidly suppress the inclination of a vehicle body by individually detecting the loads to be applied to suspensions respectively by using a load detecting means, thereby indicating the difference between the unbalancedly corresponding detected load values in a wide range, and increasing the variation of the varying speed value of the load for each suspension part which can be obtained by differentiating the detected load values. CONSTITUTION:Load detecting means 9a-9c to detect the loads to be supported by suspensions are provided. The loads to be supported by the suspensions are detected by these load detecting means 9a-9c, and the varying speed dF/dt of the detected loads are computed by load varying speed computing means 181-183. Then, the target value is computed corresponding to the varying speed of the load by target value computing means 187, 188 so that the target value may be large when the load varying speed is large while small when the load varying speed is small, and the target value is received by controllers 191-194. This constitution allows the load variation dF/dt is substantially balanced with the damping coefficient Cv to be generated by the shock absorber, and the skyhook control is realized.

摘要： PROBLEM TO BE SOLVED: To further suppress excess power consumption by an electrically driven pump for circulating a cooling medium by being powered by an electric storage device.
SOLUTION: The electrically driven pump is controlled by setting a temporary minimum duty ratio dBmintmp so that it decreases by a predetermined value α for every predetermined time t1 (S160-S240); and prior to the lapse of the predetermined time t1 after the temporary minimum duty ratio dBmintmp is set (modified), a value is set to a minimum duty ratio dBmin, the value being larger by a predetermined value β than the temporary minimum duty ratio dBmintmp at the time when a rotation speed Np of the electrically driven pump is at or falls below a threshold value Nref, so that the minimum duty ratio dBmin is updated (S250). In this way, a minimum duty ratio dBmin that reflects an individual difference of an electrically driven pump can be set, whereby excess power consumption by the electrically driven pump can be suppressed.

摘要： PURPOSE:To make the presence of any step-out in a damping force adjusting actuator detectable at all times without setting up any other special sensor such as a position encorder or the like in addition. CONSTITUTION:Estimated acceleration Gp to be found out of an equation of motion of a suspension, and a deviation DELTAG between estimated acceleration Gp to be found out of an equation of motion of a suspension, a detected car level Sh and the differential value Vr and actual acceleration Sg detected by an acceleration sensor is compared with a threshold value A, and when this deviation is large enough, it is regarded as the occurrence of step-out after the elapse of the specified time To. When this step-out happening is detected, the position of an actuator is put back to a home position, and the value of a position register is initialized. With this constitution, sky hook control over the suspension is thus performed.

摘要： PURPOSE:To secure such a sky hook controller that makes a vibration converge in a short time even if each suspension motion turns to an opposite phase in the case of wavy road running by calculating a target damping coefficient in consideration of the effect of rotation in a pitch direction, on the basis of information out of a car level sensor. CONSTITUTION:A damping force coefficient is set to a target value and controlled upon driving it in response to plural sets of shock absorbers adjusting this damping force coefficient and the target value to be given. Force F1 out of unspringing weight to be imparted to a springing mass at the front-wheel side and another force F2 out of the unspringing weight to be imparted to a springing mass at the rear-wheel side both are the sum total between spring reaction and damping force of a suspension. Relative displacement of the unspringing and the springing is calculated on the basis of each detecting output information of plural pieces of car level sensors. With this control system, respective target damping coefficients C1 and C2 of each wheel are calculated. In addition, each angular acceleration is found out of the extent of torque in both pitch and roll directions, and in consideration of the affect, a target damping coefficient is calculated.

摘要： PURPOSE:To eliminate the need for an acceleration sensor for detecting acceleration of sprung mass by providing a displacement speed calculating means for calculating vertical displacement-speed of the sprung mass based on detected signals from a distance detecting means. CONSTITUTION:A distance detecting means 103 detects relative distance, and distance change-speed calculating means 108, 109 calculate the change-speed of the relative distance. Acceleration calculating means 110, 114 calculate vertical acceleration which corresponds to the change-speed and the relative distance, and vertical displacement-speed calculating means 115, 116 calculate vertical displacement-speed. Further, target value calculating means 117, 118 calculate a target value which corresponds to the change-speed and the vertical displacement-speed to become small if the value of the change-speed is high, and to become large if the value of the change-speed is low, further to become large if the value of the vertical displacement-speed is high, and to become small if the value of the vertical displacement-speed is low. The target value calculating means then give the calculated target value to controllers 191 to 194, and thus skyhook control can be realized.
