Method and system for correcting temperature of air conditioner in vehicle

Abstract

The invention discloses a method and a system for regulating the temperature of an air conditioner in a vehicle. The method comprises the following steps: obtaining the current environment temperature outside the vehicle and the previous environment temperature outside the vehicle; presetting corresponding calculation rules according to different vehicle speed states; obtaining a target representing value of temperature outside the vehicle according to the calculation rules; accurately obtaining the temperature of the environment outside the vehicle when the temperature of an engine is different in different vehicle speed states, thereby ensuring the optimum air outlet temperature of an air conditioner controlled; the temperature in the vehicle is more approach to the current user requirements; the user comfort is improved.

Description

technical field [0001] The invention relates to the field of automobile air-conditioning control, in particular to a method and system for correcting the temperature of an air-conditioner in an automobile. Background technique [0002] In the traditional automatic air-conditioning control system of automobiles, an outside air temperature sensor is installed to detect the outside environment temperature. The air conditioner controller calculates the most suitable air outlet temperature through the information input by various sensors, such as the outside temperature sensor, the inside temperature sensor, and the sunshine sensor. [0003] However, in the actual driving process, the outside temperature sensor will inevitably be affected by the return flow of hot air from the engine, so that the outside temperature detected by the sensor does not match the actual ambient temperature, and the outlet air temperature is also affected. Contents of the invention [0004] In view o...
