摘要： PURPOSE: An SSPS(Speed Sensitive Power Steering) system by using a solenoid valve is provided to drive a vehicle stably by weighting a steering wheel with a bearing sticking to a steering rack with a magnetic bar and the solenoid valve. CONSTITUTION: An SSPS(Speed Sensitive Power Steering) system by using a solenoid valve(100) comprises a magnetic bar(122), a spring(123), a solenoid(121) and a control unit(300). The magnetic bar is embedded to a housing(120) to pressurize a bush(113). The spring is installed to the other side of the magnetic bar to pressurize the magnetic bar to the bush. The solenoid is installed to a closed end of the housing to receive an electric signal from the control unit. The control unit is connected to a speed sensor(200) sensing running speed. Therein, the control unit operates the solenoid by transmitting a signal to the solenoid valve. Thereby, steering force is improved by controlling an operation of a steering rack because the magnetic bar pressurizes the bush only with the spring.

摘要： PURPOSE: A method for controlling a power steering system of a vehicle is provided to secure safety by restraining the excessive steering of a driver when the surface of a road has a low frictional force or a deceleration is high. CONSTITUTION: A main control unit controls a steering unit to control the steering of a steering wheel corresponding to a vehicle speed(S20). The main control unit decides the operation of an ABS(Anti-lock Brake System)(S30). If the ABS is not operated, a deceleration of the vehicle is calculated(S40). The vehicle speed, deceleration and ABS operating signals are transmitted to the main control unit by an ABS control unit. The main control unit compares the deceleration to a reference deceleration(S50). If the calculated deceleration is higher than the reference one, the main control unit controls a power steering unit by limiting the increment and decrement of power steering support to a predetermined value(S60).
摘要翻译：目的：提供一种用于控制车辆的动力转向系统的方法，用于通过在道路表面摩擦力低或减速度高时通过限制驾驶员的过度转向来确保安全性。构成：主控制单元控制转向单元以控制与车速对应的方向盘的转向（S20）。主控制单元决定ABS（防抱死制动系统）的动作（S30）。如果不操作ABS，则计算车辆的减速度（S40）。车辆速度，减速度和ABS操作信号由ABS控制单元传送到主控制单元。主控制单元将减速度与参考减速度进行比较（S50）。如果计算出的减速度高于参考减速度，则主控制单元通过将动力转向支撑件的增量和减量限制在预定值来控制动力转向单元（S60）。

摘要： PURPOSE: A flow control device of a power steering and a method thereof are provided to prevent catch-up by increasing flow rate from a pump momentarily in steering suddenly during high-speed traveling, and to stabilize a system by reducing the flow rate of the pump slowly after steering suddenly. CONSTITUTION: A flow regulator improves steering performance by controlling flow from a pump according to vehicle speed proportionally. The vehicle speed and RPM(Revolution Per Minute) of a wheel are detected with a vehicle speed sensor and a wheel RPM sensor(S101). The rpm of the wheel is detected to be more than the critical value(S102), and the flow rate of the oil pump is increased momentarily with operating a solenoid valve in case of the rpm of the wheel to be over the critical value in steering suddenly(S103). The catch-up owing to shortage of output flow is prevented with compensating the flow in steering suddenly. An electronic control unit stabilizes the system by reducing flow slowly after increasing flow(S104). The flow rate is controlled proportionally according to vehicle speed in case of the rpm of the wheel to be less than the critical value(S105).
