ABSTRACT:
A cold-start control system for an internal combustion engine includes a heat estimation module, a torque request module and a propulsion torque determination module. The heat estimation module determines an exhaust system temperature and estimates heat required to heat an exhaust system to a predetermined temperature. The torque request module generates a torque request based on the estimated heat. The propulsion torque determination module determines a desired engine torque based on the torque request.
