Claims

[Scope of utility model registration request]

A vehicle power steering system comprising a power cylinder controlled by the operation of a hydraulic pressure adjustment valve based on steering of a steering wheel, wherein the hydraulic pressure adjustment is applied to an oil chamber of a shock absorber attached to the vehicle in response to the operation of the hydraulic pressure adjustment valve. a plurality of hydraulic piston means for applying hydraulic pressure from a valve; a vehicle speed sensor for detecting the vehicle running speed; and a vehicle speed sensor that detects a signal from the vehicle speed sensor and controls the steering direction of the steering wheel if the vehicle running speed is equal to or higher than a predetermined vehicle speed. 1. A power steering system for a vehicle, comprising: control means for enabling operation of a plurality of said hydraulic piston means in conjunction with said hydraulic piston means.
