摘要： A suspension control system for feedback-controlling the sprung mass acceleration signal y.sub.m and a method for introducing the unsprung mass acceleration signal y.sub.L into a tuning circuit to tune gain of an FIR filter. In this system, tuning is performed so as to cancel the road surface input y.sub.m close to a reference frequency (around 10-12 Hz). As a result, the sprung mass acts as a dynamic damper upon the road surface input y.sub.m close to the reference frequency (around 10-12 Hz), however, frequency bands other than the reference frequency band do not receive the contribution of the second term in the equation (6). That is, output from the tuning circuit to an adder becomes almost zero, and normal sky-hook control is performed. Though the sprung mass system acts as a dynamic damper, the unsprung mass system exceeds the sprung mass system in mass, and excessive resonance does not occur.

摘要： A suspension system for a vehicle has shock absorbers, each provided so as to be associated with one wheel and between sprung parts and unsprung parts, step motors, each being adapted for changing damping force characteristics of one of the shock absorbers by open loop control, and a controller for outputting control signals to the step motors. The controller is adapted for outputting control signals every predetermined time interval so as to make the damping force characteristics of the shock absorbers harder. According to the thus constituted suspension system for a vehicle, it is possible to prevent the driving stability from being lowered even when at least one of the step motors is thrown out of synchronism.

摘要： In a suspension system for a vehicle comprising a shock absorber of which damping force characteristics can be changed into four or more characteristics, detecting means detect the oscillation frequency range of the sprung member of the vehicle and a bumpy road. From the four or more damping force characteristics of the shock absorber, the number of characteristics on the higher level side are limited to two or so when the sprung member is in a low frequency oscillation range, that of the characteristics on the lower level side are limited to two or so when the sprung member is in a high frequency oscillation range, and that of the characteristics on the medium level side are limited to two or so when a road is bumpy. The damping force characteristic of the shock absorber is selected and changed on the basis of a given control rule only within the limited damping force characteristics. Thus, it is possible to prevent noise and oscillation from being caused by the large change of the damping force characteristic. Furthermore, there can be obtained comfortableness to ride in and stability on a high level.

摘要： A suspension system of a vehicle which judges the direction of a damping force of a shock absorber of damping force characteristic variable type, provided between the sprung member and the unsprung member, either oscillation-stimulating direction or oscillation-restraining direction with respect to vertical osciallation of the sprung member, and it also judges the size of the damping force of the shock absorber. The damping force characteristic of the shock absorber is set higher when it is larger than the predetermined value and it is set lower when it is less than the predertemined value. The predetermined value can be changed according to the road surface, oscillation-restraining energy becomes larger than the oscillation-stimulating energy thereby. Therefore, improvement of the comfortableness to ride in and running stability can be planned and also, noise and oscillation caused by unnecessary changes of the damping force characteristic of the shock absorber in a high oscillation frequency range due to road bumps can be reduced.

摘要： In a suspension system for a vehicle comprising a shock absorber of which damping force characteristic can be changed into three or more characteristics, the predetermined running state of the vehicle is detected by detecting means and there is limited to two or so the number of the damping force characteristics to be selected from the three or more characteristics of the shock absorber according to the running state. The damping force characteristic of the shock absorber is selected and changed on the basis of a given control rule only within the limited damping force characteristics. In addition, the threshold of the control rule is changed such that the damping force characteristic of the shock absorber can easily be changed into the higher or lower level side according to the rate of change in the predetermined running state. Thus, it is possible to prevent noise and oscillation from being caused by the large change of the damping force characteristic. Furthermore, there can be obtained comfortableness to ride in and stability on a high level.

摘要： Disposed between a sprung element and an unsprung element is a shock absorber of multi-degree variable-damping-coefficient type. The change control of the damping coefficient is carried out so that an actual damping force generated by the shock absorber can harmonize with a target damping force, Fa. The foregoing target damping force, Fa, as functions of the sprung vertical displacement velocity Xs and the unsprung vertical displacement velocity Xu, is obtained by the formula: Fa=-Xs.multidot.gs-Xu.multidot.gu, wherein both gs and gu are coefficients and the relations of gs>0; gu.gtoreq.0 hold. Thus, while controlling the sprung vertical motion, cushioning action of the wheels can be enhanced to improve traveling stabilization.

摘要： In a suspension system of a vehicle which the damping force characteristic is changed into three or more characteristics, the damping force characteristic is changed step by step when the damping force characteristic selected by a given control rule is different from the damping force characteristic at that moment in several steps. Also, the running state is detected by detecting means and the damping force characteristic to be selected is limited to two or so from three or more characteristics according to the vehicle running state. The damping force characteristic is changed only within the above selected damping force characteristics based on a given control rule. Through the above, noise and oscillation caused by large changes of the damping force characteristic can be lowered.

摘要： A traveling-path temporary-setting unit 21 sets a plurality of temporary traveling paths with different curvatures, and a calculation unit 22 calculates distances between the temporary traveling paths and preceding vehicles detected by a radar unit 1. In case of a properly-set temporary traveling path, the path and running loci of the preceding vehicles are on a concentric circle. In this case, the preceding vehicles are running along this temporary traveling path, and a time change amount of calculated distances is approximately "0". A traveling-path determination unit 23 determines, one temporary traveling path having the minimum time change amount in the distances, as a traveling path of the vehicle.

摘要： An obstacle sensing apparatus for vehicles which enables efficient obstacle sensing and improves sensing precision. The apparatus comprises a section for predicting a deduced traveling-passage on which the vehicle will travel, based on a steering angle, a yaw rate and a velocity of the vehicle, a section having a CCD camera, for detecting a current traveling-passage on which the vehicle is currently moving, a scanning-type radar unit for sensing obstacles within a predetermined area, and a danger level judging section for judging danger levels of the sensed obstacles, based on the deduced traveling-passage and the current traveling-passage. The danger level judging section sets the danger level of the obstacle sensed within an area, where the deduced traveling-passage and the current traveling-passage overlap with each other, to the highest danger level; the obstacle sensed in an area within the current traveling-passage and without the deduced traveling-passage, to an intermediate danger level; the obstacle sensed in an area within the deduced traveling-passage and without the current traveling-passage, to a lower danger level; and the obstacle sensed in an area without the current and deduced traveling-passages, to the lowest danger level.
