The invention relates to the technical field of vehicle-mounted air conditioner control, and provides an air conditioner controller external temperature updating method and system, a state detection mechanism is set, a power-off time node and a power-on time node of a vehicle are detected in a targeted manner, and the external temperature of the air conditioner controller is updated by comparing the power-off duration with the set duration. Whether the vehicle is in a preset state of repeated starting within a short time under the idling working condition is determined, then when the vehicle is normally powered on and started, the environment temperature value at the current moment is obtained, and accurate collection of environment temperature data outside the vehicle is achieved; when the vehicle is repeatedly started in a short time, the collected temperature value stored last time is directly obtained, and it is ensured that collection of the external environment temperature is not affected by water temperature heat radiation of an engine; therefore, by improving the accuracy of the temperature data, accurate in-vehicle temperature adjustment is realized, and the driving experience of a user is optimized.

    本发明涉及车载空调控制技术领域,提供一种空调控制器外温更新方法及系统,设置状态检测机制,针对性的检测车辆下电、上电两个时间节点,通过对比断电时长与设置时长的大小关系,确定车辆是否处于怠速工况下短时内重复启动的预设状态,进而在车辆正常上电启动时,获取当前时刻的环境温度值,实现车外环境温度数据的精准采集;而当车辆短时间内重复启动时,则直接获取前次保存的采集温度值,确保外接环境温度的采集不会受到发动机水温热辐射影响;进而通过提高温度数据的准确性,实现精准的车内温度调节,优化用户驾驶体验。
