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： 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： An automatic brake control system produces a warning before automatically making the braking action of a driving vehicle according to the velocities of the driving vehicle and the vehicle ahead. The system calculates the desired vehicle distance according to the velocities of the driving vehicle and the vehicle ahead, and sets a warning distance which is longer than the desired vehicle distance. The warning distance is set in accordance with the driver's feeling. According to the present invention, the system is prevented from producing undesirable warning.

摘要： When the vehicle has deviated or is deviating from a lane on which the vehicle has been or is running, the deviation of the vehicle from the lane can be suppressed, for example, by allowing the steering wheel to be operatively rotated prior to an intention of the operator. The timing of suppressing the deviation of the vehicle can be altered in accordance with conditions including, for example, the existence of a lane in the direction of deviation of the vehicle on which another vehicle is running in the same direction, the existence of an obstacle in the direction of deviation of the vehicle, the existence of an adjacent lane in the direction of deviation of the vehicle on which another vehicle is running in the opposite direction, a state of the lane on which the vehicle is running, such as a curved lane or a straight lane, a direction of deviation is outside or inside the curved lane or a lane width, a vehicle speed, a steering angle of a steering wheel, an extent of vision, and so on.

摘要： An obstacle sensing apparatus for vehicles is provided in which detection of obstacles is performed efficiently by predicting the traveling path of the vehicle appropriately when detection of obstacles by a radar unit is limited to a region along the traveling path. The apparatus is provided with a radar unit for transmitting radar waves ahead of the vehicle and sensing obstacles present ahead of the vehicle, a steering angle sensor for sensing the steering angle of the vehicle, and a yaw rate sensor for sensing the yaw rate produced by the vehicle. First traveling-path predicting device predicts a traveling path of the vehicle based upon the steering angle, and second traveling-path predicting device predicts a traveling path of the vehicle based upon the yaw rate. One of these traveling paths is selected in dependence upon the operating state of the vehicle and detection of articles by the radar unit is carried out within a limited region along the traveling path selected.

摘要： A contact preventive system for vehicles using an automatic braking device and an automatic steering device together. Contact forecasting mechanism forecasts the contact of a vehicle with an obstacle. When the contact of the obstacle is forecasted, automatic braking control mechanism operates the automatic braking device. Environment detecting mechanism detects the change of environment such as a friction coefficient of a road. Automatic steering control mechanism operates the automatic steering device to alter the advance direction of the vehicle when a possibility of contact is caused by the change of environment during automatic braking. Thus, contact can be avoided.

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.
