Reply to "SACC Power Steering"

I could be completely wrong on this and can’t cite the basis for my beliefs, but….

I thought the potentiometer on the SACC unit determines the ….maximum…. amount of power assist available, and an internal torque sensor (OEM??) determines how much of that potential assist is delivered.

for instance, parallel parking will see a lot of wheel-turning friction which in turn is transmitted into the internal torque sensor calling for power assist to be delivered.

at highway speeds, there is little or no wheel-turning friction, and thus little or no power assist is delivered.

quite willing to be confirmed or contradicted on this  🤷‍♂️
