Claims

[Scope of utility model registration request]

In a power steering system comprising a hydraulically or electrically driven actuator and a control means for controlling a steering assist force generated by the actuator, means for detecting vehicle speed;
determining means for outputting a signal to the control means that makes the steering assist force by the actuator a positive amount when the vehicle speed is below a predetermined value, and makes the steering assist force by the actuator a negative amount when the vehicle speed is above a predetermined value. A power steering device featuring:
