System Description

System Operation (cont'd)

Hydraulic Control at Each Speed Range

When stopped:

When the vehicle is stopped with the engine idling, the fluid flow is shut off because the power steering speed sensor

rotor is not rotating. The standard pressure generated by the pressure control valve is applied to the assist control valve to

move the valve to the left. When the assist control valve is in this position, the orifice valve is closed. Therefore, the fluid

discharged from the pump is fed to the low speed valve of the valve body unit. Because the low speed valve has the small

chamfer and thereby the small opening angle, the large hydraulic pressure (steering rack thrust) results in the smallest

steering force (high assist).

Middle speed range:

When the vehicle starts to move, the power steering speed sensor rotor starts to rotate as well, reducing the standard

pressure and generating the power steering speed sensor signal pressure. The valve returns to the right point where the

pressure of the power steering speed sensor signal equals the spring force of the assist control valve. When the assist

control valve is in this position, the orifice of the valve slightly opens.

Therefore, the fluid pressure from the pump is applied to the high speed valve of the valve body unit. Because the high

speed valve has a larger chamfer and the compound opening area with the low speed valve is larger than that when the

vehicle is stopped, the fluid pressure (steering rack thrust) is not generated unless the displacement angle is large (large

steering torque), resulting in moderately heavy steering (medium assist).

High speed range:

When the vehicle is driven at high speed, the power steering speed sensor rotor rotates at a high speed, greatly reducing

the standard pressure. The pressure of the power steering speed sensor signal is at the lowest value, and the assist con-

trol valve is at the right end position.

When the assist control valve is in this position, the orifice of the valve opens fully. Therefore, the fluid pressure applied to

the high speed valve is larger than when the engine speed is at the middle speed range. The compound opening area with

the low speed valve is the largest this time, and the fluid pressure (steering rack thrust) is not generated unless the dis-

placement angle is very large (low assist).
