Abstract
A control system and method for a heating system of an electric vehicle or hybrid vehicle is embodied such that when there is a heating request for a passenger compartment of the vehicle, a heating mode is set in order to heat the passenger compartment by heat from a heating circuit. In a mixed mode, an excess heat in the heating circuit is output to the surroundings, or in an excess mode, the excess heat is retained in the heating system, in order to satisfy a heating request. In the mixed mode, a degree of opening of the heating circuit is set such that only a partial quantity of coolant from the heating circuit is exchanged with a cooling circuit. The mixed mode is activated if the excess heat in the heating circuit exceeds a threshold value which is determined in accordance with an external temperature.
