Method for setting mid-point potential of power assisted steering servo system employing a microprocessor

摘要

In an amplifier (10) the signal from the torque sensor (2) is subjected to temperature compensation controlled by a microprocessor (12). In a following circuit (13) the same processor corrects the final output signal (Ts) so that when the steering wheel is in the mid position it has a value identical with that recognized by the power steering control computer
