Abstract:
1. A method for inhibiting torque steer in a vehicle equipped with steerable wheels that are power driven, the method comprising the steps of: determining a maximum engine torque limit, above which an unacceptable amount of torque steer is produced; estimating a driver-requested engine torque; comparing the maximum engine torque limit with driver-requested engine torque; providing a torque control signal, which is the lower of said maximum engine torque limit and the driver-requested engine torque, to a throttle angle calculator in an engine control system; providing an engine speed signal to said throttle angle calculator; using said torque signal and said engine speed signal to determine a calculated torque steer inhibiting throttle command that is used to adjust the throttle angle; and adjusting a throttle angle so that actual engine torque is approximately equal to a lower one of the maximum engine torque limit and the driver-requested engine torque.
