Abstract

The invention provides an automobile heating system which comprises a heating ventilation air conditioning (HVAC) assembly, an auxiliary heating device and a controller, wherein the HVAC assembly has a blower and a ventilator; the auxiliary heating device is connected with the ventilator; and the controller comprises an HVAC control module and a control module of the auxiliary heating device, and the control module of the auxiliary heating device is connected with the HVAC control module through a relay, the HVAC control module and the HVAC assembly are connected together for controlling the on/off of the HVAC assembly, the control module of the auxiliary heating device is connected with the auxiliary heating device for controlling the on/off of the auxiliary heating device, wherein according to the car key shifts, engine state, HVAC assembly blower shifts and the operation mode of the HVAC assembly, the HVAC control module allows or forbids the starting of the auxiliary heating device through controlling the control module of the auxiliary heating device by the relay.

Description

technical field [0001] The invention relates to a heating system for automobiles and a control method thereof. Background technique [0002] The heat of the heater in the traditional vehicle air-conditioning system (especially the air-conditioning system for heavy-duty trucks) is provided by the engine cooling water. When heating is required for parking, the engine consumes a lot of power, makes a lot of noise, and is poor in economy and comfort. Under extremely cold conditions, the temperature of the engine coolant used in the car is too low to provide the heat required by the heating system, and the defrosting and heating effects are not ideal. [0003] For this reason, auxiliary heating devices have appeared in the prior art, see EP 0 331 922 B1 and US 5,855,319. However, the above-mentioned auxiliary heating device in the prior art is independent of the HVAC system of the vehicle, has a large number of elements, complicated structure and control, and high manufacturing ...
