The invention belongs to the technical field of vehicle detection, and discloses a refrigerant detection method, device and equipment and a storage medium. The method comprises the steps that if it is detected that a vehicle is started in a cold mode, the environment temperature and the vehicle-mounted air conditioner pressure are obtained; a static air conditioner pressure threshold value corresponding to the environment temperature is searched for; determining a static pressure interval according to the error value and a static air conditioner pressure threshold value; and the vehicle-mounted air conditioner pressure is compared with the static pressure interval, and whether the refrigerant is sufficient or not is determined. The static air conditioner pressure threshold value corresponding to the calibrated refrigerant quantity lower limit value at the environment temperature is found through the environment temperature, the vehicle-mounted air conditioner pressure is compared with the calibrated static air conditioner pressure threshold value, and in the comparison process, the influence of a sensor or the temperature in a vehicle cabin is also considered, so that the vehicle-mounted air conditioner pressure can be accurately detected. It is ensured that whether the refrigerant of the vehicle-mounted air conditioner is sufficient or not can be accurately detected, and therefore refrigerant detection of the vehicle-mounted air conditioner in a vehicle is achieved.
本发明属于车辆检测技术领域,公开了一种冷媒检测方法、装置、设备及存储介质。本申请通过若检测到车辆冷车启动,则获取环境温度以及车载空调压力;查找环境温度对应的静态空调压力阈值;根据误差值及静态空调压力阈值确定静态压力区间;将车载空调压力与静态压力区间进行比较,确定冷媒是否充足。由于是通过环境温度查找到标定的该环境温度下冷媒量下限值对应的静态空调压力阈值,通过将车载空调压力与标定的静态空调压力阈值进行对比,且在对比过程中,还考虑到了传感器或车舱内温度的影响,保证了可准确检测车载空调的冷媒是否充足,从而实现了对车辆中车载空调的冷媒检测。
