    摘要： A method and system for controlling a vehicle suspension system comprise determining a relative velocity between a wheel and a corresponding corner of the vehicle, and determining responsive to the relative velocity a raw wheel demand force. The method and system also comprise determining a relative position between the wheel and the corresponding corner of a vehicle body, determining a scale factor responsive to the relative position of the wheel, modifying the raw wheel demand force as a function of the scale factor to determine a scaled wheel demand force, and controlling the vehicle suspension system responsive to the scaled wheel demand force.

    摘要： A method of the invention is for controlling an MR-fluid hydraulic mount connected to a vehicle engine. The mount includes an internal MR-fluid cavity. The mount includes a partition plate assembly partitioning the cavity into first and second MR-fluid chambers. The partition plate assembly has an orifice extending from the first MR-fluid chamber to the second MR-fluid chamber. The mount includes an electric coil positioned to magnetically influence the orifice. The method includes, when the vehicle engine is at idle, determining a reference pressure as a fluid pressure within the second MR-fluid chamber. The method includes, when the vehicle engine is above idle, determining a command electric current to be applied to the electric coil using at least a difference between the reference pressure and a current fluid pressure within the second MR-fluid chamber. The method includes applying the command electric output current to the electric coil.

    摘要： A suspension system having a frame, a cab having a front portion pivotally mounted to the frame and at least one actuator mounted between a rear portion of the cab and the frame. A position sensor is mounted adjacent the rear portion of the cab for generating a first signal indicating a position of the cab relative to the frame, an accelerometer is mounted to the frame for generating a second signal indicating an acceleration of the frame relative to gravity and an electronic control receives the first and second signals from the position sensor and the accelerometer and generates a control signal for controlling the actuator in response to the first and second signals.

    摘要： A brake apparatus and method utilize an electric power brake booster for operating a push rod actuated hydraulic master cylinder. The existing vehicle electrical system provides electric power for the power brake booster, thus eliminating the need for engine driven or auxiliary pressure/vacuum sources. The electric power brake booster includes an electrically powered actuator having an output shaft adapted for operative connection to the master cylinder, and an input for receipt of a signal indicative of force applied to the push rod. The electrically powered actuator augments the force applied to the push rod in response to the signal indicative of the force applied to the push rod. The booster may include a sensor for sensing force applied to the push rod and generating the signal indicative of the force applied to the push rod.
