A method and system for inhibiting torque steer in a vehicle equipped with steerable
wheels that are power driven. The method determines a maximum engine torque limit,
determines an estimated driver-desired torque, and controls the actual torque,
by adjustment of the throttle angle, to be the smaller of the maximum engine torque
limit and the estimated driver-desired torque. Sensors measure steering angle and
transmission gear position and a calculator determines the maximum engine torque
limit based upon the steering angle and transmission gear position. Further sensors
measure engine speed, throttle angle, and atmospheric pressure, and a calculator
estimates driver-desired torque based upon the measured engine speed, throttle
angle, and atmospheric pressure. A comparator selects the lower of the maximum
engine torque limit and the driver-desired engine torque and uses the selected
torque to control throttle angle to inhibit torque steer.
