PUMP SPEED COMMAND GENERATION ALGORITHM FOR MAGNETORHEOLOGICAL POWER STEERING COUPLING

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.
