摘要： A method and system for providing variable load control and isolation in a vehicle suspension includes a variably flexible suspension element coupled between the frame of the vehicle and the wheel. The variably flexible suspension element comprises an electrically responsive material disposed therein that varies stiffness in response to electrical control signals applied thereto. The electrical control signals are generated by an electronic control unit and are representative of road conditions traveled by the vehicle as sensed by at least one sensor.

摘要： A vehicle suspension system is dynamically adjustable to minimize the effects of energy transfer on a driver, passenger or cargo within a vehicle. Each wheel preferably has a suspension module that includes a force absorbing device with an adjustable force absorbing capacity. A sensor is associated with each wheel that detects an amount of displacement and acceleration of the wheel in response to a force imposed on the vehicle as caused by variations in a road surface, for example. An electronic controller detects the amount of displacement and acceleration of one wheel and activates an electrically activated force imposing device at another wheel to effectively counteract the effect of the force on the one wheel within one millisecond. The force imposing device preferably is a piezoelectric actuator. The vehicle suspension system of this invention is dynamically adjustable and compensates for variations in a road surface, for example, while the vehicle is in transit.

摘要： When a road surface is judged to be undulating and rough, a parameter for a bad road to attain “soft” damping force characteristics is set with priority to setting of a parameter for an undulating road to attain “hard” damping force characteristics. Consequently, “soft” damping force characteristics are obtained to improve the ride quality. This order of the priority is adopted especially when a vehicle speed is low. When the vehicle speed is high, the order of the priority is reversed.
