摘要： In a suspension system for a vehicle, a suspension spring, an absorber for controllably changing the damping coefficient becoming the reference of amount of its own generating damping force, a displacement force generator for controllably generating a displacement force are arranged in parallel between sprung and unsprung members. A vibration damping control is executed based on a so-called skyhook damper theory by utilizing the displacement force. In execution of the vibration damping control, when a sign of sprung-member absolute velocity Vu and a sign of sprung/unsprung-members velocity difference ΔV are the same to each other, a damping-coefficient increasing control is executed to set a target damping coefficient C* of the absorber to a coefficient value C2 that is larger than a coefficient value C1 to which the target damping coefficient C* is set when the sign of sprung-member absolute velocity Vu and the sign of sprung/unsprung-members velocity difference ΔV are different from each other. Vibration of the sprung member can be effectively damped by cooperation of the absorber and the displacement force generator.

摘要： A method and algorithm for semi-active suspension damper control is described. The algorithm controls the damper setting to limit vehicle body movement in terms of body modal velocities of heave, roll and pitch. The main input, body movement, is measured with accelerometers. The control output comprises a request in percent of damper control range. Vehicle speed-dependent minimum and maximum limits are applied. The method includes monitoring vehicle speed and a modal sensing system. A common damping rate for the dampers is determined based upon parameters for speed, heave, pitch, and roll. Each damper is controlled based upon the common damping rate adjusted based upon a location of each of the controllable suspension dampers. The output comprises a single signal, translated to a front and rear setting. The purpose is to always have a balanced setting of the four dampers.

摘要： An active vehicle suspension system includes an active damping mechanism operatively coupled to a vehicle wheel and configured for controlling a damping force applied to the wheel responsive to a control signal. A controller is operatively coupled to the damping mechanism and configured for generating a control signal to the damping mechanism responsive to velocity of the wheel in a downward vertical direction. At least one of a timer threshold and velocity threshold, used to determine whether a vehicle wheel has encountered a depression in a road surface, may be varied on a basis of a speed of the vehicle. A damping mechanism for a rear wheel of a vehicle may be controlled on a basis of how a damping mechanism for a front wheel is controlled.

摘要： An ECU of an ECS apparatus has a determination block for determining whether the TPS signal rises to be greater than a first reference value and for determining whether the TPS signal declines to be less than a second reference value; and a damper control block, which adjusts a damping force of the front damper according to the determination result. The damper control block sets the front damper into a hard rebound mode when the determination block determines that the TPS signal rises to be greater than the first reference value, and then the damper control block sets the front damper into a hard compression mode when the determination block determines that the TPS signal declines to become less than the second reference value.
