I'm trying to develop a car driving game using a steering wheel.I am
recieving two signals indicating the position and torque from the
steering wheel.I want to know how the power steering feature depends on
these two signals.what impact the torque signal has on the wheel's
turning control.Does the torque decide the angle of turning or the
speed of turning.what does the torque signal indicate.

I would also like to know how the power steering feature depends on the
vehicle speed.Does the sensitivity of the power steering change with
vehicle speed .If so how ?

I think you should ask these questions in rec.autos.tech rather than
here.

For instance, speed-sensitive power assist does exist (generally
in high-end cars), I don't know how it's implemented in most cases
(although I would speculate it's some sort of pop-off valve driven
by electronic control from the speed sensor.)

The position of a real steering wheel controls the angle of the wheels on
the road, assuming nothing's broken and allowing for some play in the
system. Torque is how hard the wheel is being turned; what it means
to you depends on whether or not this is a force-feedback wheel.

In my car, there's an arrangement where the centrifugal force (yeah,
yeah, I know) of the power steering pulley moves a diverter which
causes the power steering fluid to bypass the pump. The faster the
pulley spins, the less power assist you get. This arrangement leads
to power assist which drops off based on engine speed.

Why try to simulate power steering in a driving game, though?

There's no such thing as a free lunch, but certain accounting practices can
result in a fully-depreciated one.
