ABSTRACT:
A vehicle traction control system is controlled in-part by a signal value indicative of estimated wheel torque. The estimated wheel torque value is produced within the vehicle's electronic engine control (EEC) module by summing a first value which indicated the estimated torque attributable to engine combustion and a second value which is proportional to engine acceleration/deceleration which indicates the amount of torque attributable to the inertial movement of engine and drive train masses. Before summing the two signal components, the signal which indicates combustion torque is delayed with respect to the signal indicating inertial torque by a delay interval whose duration varies with engine speed to take into account the delay between intake fuel rate changes and combustion forces as well as delays attributable to the timing of the calculations themselves.
