The invention provides a fastener looseness identification method and device, electronic equipment, a medium and a vehicle, and the method comprises the steps: receiving a first output voltage, uploaded by a target vehicle, of a DCDC in a working state of the DCDC; acquiring a second output voltage of the storage battery uploaded by the target vehicle; acquiring a voltage difference value between the first output voltage and the second output voltage; and according to the voltage difference value and a preset fastener loosening judgment strategy, whether the low-voltage charging loop fastener of the target vehicle is loosened or not is judged. According to the method and the device, the looseness identification of the fastener is realized under the scene of not influencing the use of the vehicle by the user, so that the fault diagnosis of the target vehicle in the driving process is realized, the timeliness of the fault diagnosis of the target vehicle is improved, and the user experience is improved. The possibility of safety abnormity of the target vehicle caused by loosening of the fastener on the low-voltage charging loop is reduced, the driving safety of the target vehicle is improved, and the driving experience of a user is optimized.

    本申请提出了一种紧固件松动识别方法、装置、电子设备、介质和车辆,其中,方法包括:接收目标车辆上传的车载变压单元DCDC工作状态时DCDC的第一输出电压;获取目标车辆上传的蓄电池的第二输出电压;获取第一输出电压和第二输出电压的电压差值;根据电压差值和预设的紧固件松动判断策略,判断目标车辆的低压充电回路紧固件是否松动。本申请中,在不影响用户使用车辆的场景下,实现了对紧固件的松动识别,进而实现了对驾驶过程中的目标车辆的故障诊断,提高了目标车辆的故障诊断的时效性,降低了由于低压充电回路上的紧固件的松动导致目标车辆出现安全异常的可能程度,提高了目标车辆的驾驶安全性,优化了用户的驾驶体验。
