Abstract
A thermal management system for a vehicle and a method for controlling the same are provided. The thermal management system comprises a first coolant circuit, a second coolant circuit, a refrigerant circuit, and a controller. The first coolant circuit includes at least a first coolant circuit heat exchanger, a Coolant Heater Control Module (CHCM), a CHCM mixing valve, and a bypass valve. The CHCM mixing valve is configured to modulate flow of a coolant between the first coolant circuit heat exchanger and the CHCM. The bypass valve is configured to link the first coolant circuit with the engine. The controller directs the thermal management system to operate in one of a high efficiency mode, a heat pump assist mode, a maximum performance mode, and a propulsion system energy improvement mode, effectuating the selected mode of operation via the actuation of the CHCM valve and the bypass valve to predetermined positions.
