Control method of vehicle air conditioner system

Abstract

The invention relates to a control method of a vehicle air conditioner. Using conditions of the air conditioner are reasonably controlled to enable an existing hybrid power system vehicle to save more energy. According to the technical scheme, an air condition controller completes the following steps: starting an air conditioner, initializing parameters of the air conditioner, inputting the preset temperature T0 into the air condition controller, enabling the air condition controller to obtain the preset temperature T0 and the in-vehicle temperature T1, comparing the preset temperature T0 with the in-vehicle temperature T1, judging whether an engine of the vehicle is started or not at present, judging whether the vehicle is stayed in a preset work condition at present, and enabling an air condition compressor to work. According to the control method, the air conditioner driving mode is reasonably controlled, and the energy-saving efficiency of the system is further improved.

Description

technical field [0001] The invention relates to a control method of an air conditioner compressor for a vehicle, belonging to the field of vehicle control. Background technique [0002] Hybrid vehicles have received strong support from the government and society in recent years, thanks to their high fuel efficiency and low emissions. Ideally, the fuel saving rate of hybrid vehicles can reach more than 50%, but people's pursuit of energy saving is not limited to this. Over the years, technical experts have been working hard to explore, hoping to further improve the energy efficiency of new energy vehicles. The use of vehicle air conditioners makes people fully feel the comfort and convenience brought by modern technology, but when traditional vehicle air conditioners are applied to hybrid vehicles, they encounter unprecedented obstacles.

The use of car air conditioners makes people fully feel the comfort and convenience brought by modern technology, but when traditional car air conditioners are applied to hybrid vehicles, they encounter unprecedented obstacles

Because the traditional vehicle air conditioner is generally a mechanical air conditioner, the air conditioner compressor is connected to the engine shaft with transmission parts, and the engine is used to directly drive the compressor to rotate, thereby cooling or heating; When the engine is turned off at low speed or idle speed, the air conditioner must be turned off at this time, which brings great inconvenience to the temperature adjustment in the car

For this reason, technical experts have designed an electric-mechanical dual-purpose air conditioner. When the vehicle is running purely electric, the air conditioner is driven by electricity, and when the vehicle is driven by the engine, the engine is used to drive the air conditioner, which solves the problem that the air conditioner of the hybrid vehicle cannot be used throughout.

However, there are still problems in the control of the air conditioner of hybrid vehicles, that is, the control of the air conditioner is still solving the problem of "use", and few people pay attention to the problem of "energy saving" of the air conditioner
