VEHICLE THERMAL MANAGEMENT SYSTEM AND METHOD FOR CONTROLLING THE SAME

A vehicle thermal management system includes a HVAC subsystem; a power electronics cooling subsystem; a plurality of heat recovery drive components; and a controller. The controller includes a required heat calculation module to calculate a required heat quantity for a heating operation of the HVAC subsystem. The controller includes a coefficient of performance (COP) calculation module to calculate a maximum COP of the HVAC subsystem in the heating mode and a heat recovery calculation module to calculate a maximum heat recovery quantity of the HVAC subsystem and a total sum of estimated heat recovery quantities recoverable from the plurality of heat sources. The controller also includes a power determination module to determine respective amounts of power input to the plurality of heat recovery drive components based on the total sum of estimated heat recovery quantities and the maximum heat recovery quantity.
