Embodiment Construction

[0042] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0043] figure 1is a schematic diagram of a heating system for a hybrid vehicle provided by an exemplary embodiment. Such as figure 1 As shown, the heating system may include a first three-way valve 1 , a second three-way valve 2 and a water pump 3 . Wherein, the first outlet 1a of the first three-way valve 1 communicates with the residual hot water of the engine and then communicates with the inlet 3a of the water pump 3 . The second outlet 1b of the first three-way valve 1 is directly connected to the inlet 3a of the water pump 3, the inlet 2c of the second three-way valve 2 is connected to the outlet 3b of the water pump 3, and the first outlet 2a of the...

Abstract

The present disclosure relates to a control method, apparatus and vehicle for a heating system of a hybrid vehicle. The heating system includes a first three-way valve (1) and a second three-way valve (2), the first three-way valve (1) is used to control the amount of water flowing into the waste water circuit of the engine, and the second three-way valve (2 ) is used to control the distribution of the water flow into the cockpit heating circuit and the water flow into the battery heating circuit. The method includes: controlling the opening of the first three-way valve (1) according to the first water temperature difference. The difference between a target water temperature and the current water temperature at the heater water inlet in the cockpit heating circuit. In this way, the heat of the residual hot water of the engine can be reasonably utilized, thereby saving energy.

Description

technical field [0001] The present disclosure relates to the field of vehicle control, in particular, to a control method, device and vehicle for a heating system of a hybrid vehicle. Background technique [0002] The so-called hybrid vehicle refers to a hybrid electric vehicle (Hybrid Electric Vehicle, HEV), which uses a traditional internal combustion engine (diesel engine or gasoline engine) and a power battery as a power source. The working mode of the hybrid vehicle can include series, parallel and series-parallel (or hybrid) type. Hybrid vehicles have two sets of power systems, plus the management and control systems of the two sets of power systems, the structure is complex and the technology is relatively difficult. [0003] With the increasingly stringent environmental protection measures around the world, hybrid vehicles have become a focus of vehicle research and development due to their energy-saving and low-emission characteristics, and have begun to be commerc...
