Abstract:
An engine control system comprises a torque determination module, a limit determination module, a torque limit module, and a torque control module. The torque determination module determines a desired torque based on a desired engine speed. The limit determination module determines a torque limit based on one of an engine oil temperature and a transmission fluid temperature. The torque limit module determines a final torque based on the desired torque and the torque limit. The torque control module selectively determines a throttle area based on the final torque. A throttle valve is actuated based on the throttle area.
