摘要： Upon searching control parameter used to adjust damping force of a damper from a map in accordance with damper speed and target damping force decided based on moving condition of the vehicle, the map sets the control parameter, which are relatively higher than the actual damping force characteristics, as map data in the area where the damper speed is less than a predetermined value, the area where the noise has the great influence on the sensor outputs. Therefore, it can be prevented that the control parameter of the damping force is varied largely or varied in a short period by the influence of noise, and the driving stability control of the vehicle can be executed exactly and the noise caused by switching the damping force of the damper can be reduced.

摘要： An active actuator is interposed between the unsprung mass and the sprung mass of a vehicle, and a controller selectively extends and retracts the actuator at a prescribed acceleration so as to selectively apply an additional contact load to the wheel by making use of the inertial force of the sprung mass and/or the unsprung mass of the vehicle. Thus, the tire contact load of each wheel can be increased at will and independently from the other wheels so that the gripping force available to each wheel can be increased as required by appropriately operating the corresponding actuator. Therefore, the braking performance and the accelerating performance for the given road condition can be improved. Additionally, even when a frictional coefficients for the right and left wheels differ from each other, by appropriately applying an additional contact load to the wheel travelling over the more slippery part of the road surface, the stability of the vehicle can be also substantially increased.

摘要： An active actuator is interposed between the unsprung mass and the sprung mass of a vehicle, and extended and retracted in a cyclic manner so as to apply a prescribed reaction to the unsprung mass during an extending stroke of the actuator. Thus, the additional contact load is applied to the tire in a cyclic manner over a desired period of time so that the gripping force of the tire can be increased over a desired period of time. Although the increase in the tire contact load and the reduction in the tire contact load occurs in an alternating, cyclic manner, it is possible to achieve an overall advantage for instance in reducing the braking distance by intermittently increasing the tire contact load of the rear wheels by detecting the braking action of the vehicle with a suitable acceleration sensor or the like. In particular, by setting a retracting stroke of the actuator substantially longer in time duration than an extending stroke of the actuator, it is possible to reduce the degree of the contact load reduction between each consecutive phase of contact load increase, and to achieve an even better overall result.

摘要： The wheel suspension system (2,3) has an unsprung mass containing one wheel on a sprung mass containing a car body. An active final control element (5) is located between the sprung and unsprung masses. An open or closed loop control device (18) extends the control element with a specified acceleration in order to lend the wheel an additional contact load. For a number of wheels, a final control element is provided and the control device is set up to extend at least one of the control elements with a specified acceleration without retracting one of the remaining ones.

摘要： The apparatus has an actuator (5) mounted vertically between a bottom suspension arm (3) and a chassis of a vehicle. The ground load of a tyre (1) is varied based on the inertia generated by the vertical movement of the actuator during acceleration. The ground load is varied continuously in accordance with the expansion and shrinkage of the actuator due to the road reaction force.

摘要： An active suspension system and an active suspension control method for a vehicle having a first wheel set and a second wheel set, comprising a power actuator interposed between the vehicle body and each of the wheels; a sensor for detecting turning maneuver of the vehicle; and a control unit for controlling operation of the actuators according to data obtained from the sensor so as to reduce a vertical load acting on the inner wheel of the second wheel set which bears a less vertical load than the first wheel set during the turning maneuver. Thereby, the shifting of the vertical load between the wheels of the first wheel set is reduced with the result that the overall cornering force of the vehicle is maximized because of the saturating property of the maximum cornering force of the tire in relation with the vertical load acting thereon.
