摘要： A power steering device sets an applied friction torque applied to a steering wheel based on a real steering angle and a target steering angle, and performs a control of applying the applied friction torque to the steering wheel. An applied friction torque changing unit changes the applied friction torque, which is calculated from the real steering angle and the target steering angle, when the vehicle reverses. Concretely, the unit changes the applied friction torque to a smaller value when the vehicle reverses than that when the vehicle advances. Thereby, it is possible to decrease the applied friction torque properly when the vehicle reverses, and it become possible to improve the maneuverability of the steering wheel.

摘要： A power steering apparatus of rack-and-pinion type comprising an input shaft steered by a driver, an output shaft operatively connected to a rack bar through a rack-and-pinion gear mechanism, a hydraulic cylinder operatively connected to the rack bar, and a rotary valve operatively connected to the input shaft. The steering apparatus further comprises an intermediate rotary member disposed between the input shaft and output shaft for rotation about an axis offset from the rotational axis of the output shaft, and a reduction gear mechanism arranged between the rotary valve and the intermediate rotary member. A cam mechanism is disposed between the intermediate rotary member and the output shaft for transmitting the rotation of the intermediate rotary member to the output shaft. The cam mechanism is composed of a cam groove formed on one of the intermediate rotary member and output shaft, and a follower roller provided on the other of the intermediate rotary member and output shaft to be engaged with the cam groove.

摘要： An object of the present invention is to provide an electric power steering device which reduces the variation of viscous feeling due to the change of steering velocity and presents better steering feeling than conventional power steering devices. A basic assist torque Tab and the like are calculated; filter parameters such as time constant Tn are calculated; and a gain Gs is calculated. A steering velocity s·θ is calculated and a correction torque Tcmps is calculated as a product of a gain Gs and a value obtained by filtering steering velocity s·θ with a filter of second-order lag and first-order advance. Further, a final target assist torque Ta is calculated by summing a basic assist torque Tab and the like and a correction torque Tcmps, and a steering assist torque is controlled so that it conforms to the final target assist torque Ta.
