发明名称 Electric power steering apparatus
摘要 An electric power steering apparatus, which provides a steering assist of an electric motor directly to a vehicle steering system to reduce necessary steering power to be applied by a vehicle driver, is provided with a control unit which includes a proportion-coefficient and integration-coefficient setting section for, on the basis of a velocity of the vehicle detected by a velocity sensor, setting sensitivity of a proportioning element and integration gain of an integrating element in such a manner that they take greater values during high-velocity running of the vehicle than during low-velocity running of vehicle. This prevents occurrence of unwanted noises and vibrations during low-velocity running of the vehicle and also enhances steering response during high-velocity running of the vehicle, thus always providing an optimum steering feeling in changing running conditions of the vehicle. The control unit may further include a compensation section provided between an offset calculation section and a proportional and integral control section for, on the basis of the velocity detected by the velocity sensor, modifying the offset signal in such a manner that the offset signal takes a greater value during high-velocity running of the vehicle than during low-velocity running of vehicle.
