A method and device for suspending a wheel axle from a vehicle includes a unitary flexible member coupled between the vehicle and the wheel axle and to an electronic control unit. The flexible member is formed of a material that changes shape in the presence of electrical signals having a varying signal strength. The electronic control unit, upon receiving various suspension related inputs, transmits the electrical signals having the varying signal strength to the unitary flexible member to change the shape thereof in order to vary the stiffness of the flexible member and thus control the suspension of the vehicle.

Method and device for actively suspending a wheel from a vehicle

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.

Method and system for providing variable load control and isolation in a vehicle suspension

A method and system for predicting the condition of a road to be travelled by a vehicle includes a measurement device, such as a laser or machine vision system, disposed at a front of the vehicle for measuring a vertical elevation of a portion of the road at a predetermined distance ahead of the vehicle. A control unit, in communication with the measurement device, has control logic for predicting the condition of the road to be travelled by the vehicle based on the measured vertical elevation and controlling an aspect of the vehicle, such as the vehicle's suspension system, based on the predicted road condition.

Method and system for predicting road profile

A method and system for floating an upper vehicle part from a lower vehicle frame includes a primary floating device, coupled to either the upper vehicle part or the lower vehicle frame, floats the upper vehicle part freely separate from the lower vehicle frame. A plurality of sensors sense appropriate road inputs. An electronic control unit, coupled to the primary floating device and the plurality of sensors, receives the road inputs and generates control signals for controlling the primary floating device in order to minimize movement of the upper vehicle part with respect to the lower vehicle frame.
