Abstract

The invention relates to the field of new energy automobile control, and provides a vehicle air conditioner control method and system. The vehicle air conditioner control method comprises the steps ofobtaining environment information of a vehicle air conditioner, wherein the environment information of the vehicle air conditioner comprises a cab temperature; judging whether the current vehicle airconditioner environment state belongs to an air conditioner comfortable environment state expected by a driver or not according to the environment information of the vehicle air conditioner; controlling the vehicle air conditioner to execute a first working mode when the current vehicle air conditioner environment state does not belong to the air conditioner comfortable environment state; and controlling the vehicle air conditioner to execute a second working mode when the current vehicle air conditioner environment state belongs to the air conditioner comfortable environment state, wherein the second air conditioner power upper limit value of the vehicle air conditioner under the corresponding second working mode is less than the first air conditioner power upper limit value under the corresponding first working mode. Therefore, balanced control over the comfort degree and the energy saving performance of the air conditioner in the vehicle is achieved, the comfort degree experience of a user is guaranteed, the energy saving performance of the vehicle can be improved, and the endurance of the vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of new energy vehicle control, in particular to a vehicle air conditioning control method and system. Background technique [0002] In recent years, the battery life of electric vehicles has always been the focus of attention, and the air conditioning system has always had a significant impact on the excessive energy consumption of pure electric vehicles. In addition, compared with traditional fuel vehicles, the compressor of the air-conditioning system in electric vehicles is driven by a motor, which makes the traditional air-conditioning control method lead to high energy consumption and low work efficiency of the air-conditioning system of pure electric vehicles. In addition, with the continuous innovation of automotive technology, users have higher and higher requirements for air-conditioning vehicle comfort. Therefore, how to achieve a good balance control between vehicle comfort and energy-saving cont...
