Abstract
A system (10) for compensating torque steer in a vehicle power assist steering system for a front wheel drive vehicle includes an engine speed sensor (60) or a road wheel drive torque sensor (61). A torque sensor (32) senses applied steering torque. A steering assist motor (28) provides power assist to assist the vehicle operator in steering the vehicle. A controller (62) controls the power assist motor in response to the sensed applied steering torque and in response to one of the sensed engine speed or the road wheel drive torque to compensate for torque steer.
