Heating system and control method for a range-extended hybrid electric vehicle

Abstract

The invention discloses a heating system of an extended-range type hybrid vehicle and a control method and relates to the technical field of vehicles. The heating system of the extended-range type hybrid vehicle is used for collecting heat to a passenger compartment to increase the temperature of the passenger compartment and comprises a first pipeline, a first heat exchanger, an extended-range type engine, a power engine, a second pipeline, a heater and a water pump, wherein the first heat exchanger is positioned in the first pipeline; the extended-range type engine communicates with the first pipeline to form a first circulating loop; the engine power communicates with the first pipeline to form a second circulating loop; the second pipeline communicates with one part of the first pipeline to form a third circulating loop; the first heat exchanger is positioned in one part of the partial first pipeline; the heater is positioned in the third circulating loop; and the water pump is positioned in the third circulating loop. The invention further provides a corresponding method. The heating system of the extended-range type hybrid vehicle has the advantages that the integration degree is high, the space occupied by the heating system in the vehicle can be effectively reduced, and the manufacturing cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a heating system and a control method of a range-extended hybrid electric vehicle. Background technique [0002] Traditionally powered vehicles often use engine waste heat as a heating source to increase the temperature of the passenger compartment, while electric vehicles use heaters as a heating source to increase the temperature of the passenger compartment. For a range-extended hybrid vehicle with two internal combustion engines and one battery system that can run purely on electric power, in order to meet the heating needs in different operating modes, it is necessary to collect engine waste heat as a heating source when the engine is working, while the battery The system uses the heater as a source of heating when powered. [0003] However, when collecting heat in the above-mentioned different operating modes, the heating circuits are separated, that is, the heat is colle...
