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 high-voltage accumulator, an HVA heating mode is activated in which the high-voltage accumulator which is connected to an HVA circuit of the heating system is heated by an HVA heating source which is activated for this purpose so that heat is generated in the HVA circuit or transferred into the circuit. When there is a heating request for a passenger compartment of the vehicle, an air-conditioning heating mode is activated in which the passenger compartment is heated by a heating circuit, with heat which is generated in the heating circuit with an auxiliary heater or is transferred into the heating circuit with a heat pump, or both. When the air-conditioning heating mode is activated, it is determined whether or not there is a heating deficit which indicates whether the heating request can be completely satisfied with the auxiliary heater or with the heat pump or with both. If there is a heating deficit, an auxiliary heating mode is activated in which heat of the HVA heating source is transferred from the HVA circuit into the heating circuit by the heat pump in order to compensate the heating deficit.
