摘要:
An engine control system for a vehicle comprises a torque module and a drag request evaluation module. The torque module controls torque output of an engine based on a driver torque request and increases the torque output based on a wheel drag torque request generated based on a driven wheel speed. The drag request evaluation module disables the increase of the torque output when the driven wheel speed is greater than an undriven wheel speed by more than a predetermined speed.
