摘要： A method for determining a speed of a power steering pump used in a power steering assembly of a vehicle that has particular application in a vehicle using a magneto-rheological hydraulic power steering (MRHPS) system for improving the fuel efficiency and ride comfort of the vehicle, and for reliable functioning of the power steering system. The method includes determining an angle of rotation of the steering wheel and a rate of change of the angle of rotation of the steering wheel based on the angle of rotation of the steering wheel of the vehicle. The method further includes determining the speed of the vehicle and the speed of the power steering pump based on the angle of rotation of the steering wheel, the rate of change of the angle of rotation of the steering wheel and the speed of the vehicle.

摘要： A linear actuator associated with an actuator system for a device includes a wire cable fabricated from an active material. The linear actuator couples to the device and to the moveable element. The active material induces strain in the linear actuator in response to an activation signal. The linear actuator translates the moveable element relative to the device in response to the induced strain. An activation controller electrically connects to the linear actuator and generates the activation signal. A position feedback sensor monitors a position of the moveable element.
