The invention provides an internal fault diagnosis method, an electronic device and a vehicle, which can diagnose an internal fault again according to a preset time interval, and avoid missing detection of the internal fault of an air bag control unit during two adjacent power-on periods caused by single diagnosis. Whether an internal fault exists or not is further verified by comparing the actual acceleration signal with the calculated acceleration signal, and the accuracy of fault diagnosis is improved. And when the acceleration difference value exceeds a standard value, performing continuous detection verification according to a preset first detection frequency, and if the continuous detection verification is not passed, determining that the airbag control unit has an internal fault, and lightening an airbag fault lamp. And vibration caused by seat assembly or acceleration exceeding or distortion caused by other abnormal vibration are eliminated by adopting a continuous multi-time detection scheme, so that misjudgment is avoided.
本申请提供一种内部故障的诊断方法、电子设备及车辆,能够根据预设的时间间隔进行内部故障的重新诊断,避免单次诊断导致的相邻两次上电期间气囊控制单元发生内部故障的漏检。通过比较实际加速度信号和计算加速度信号进一步验证是否存在内部故障,提高故障诊断的准确性。在加速度差异值超过标准值时,根据预设的第一检测频率进行连续检测验证,若未通过连续检测验证,确定气囊控制单元发生内部故障,点亮气囊故障灯。采用连续多次检测的方案排除装配座椅导致的振动或其他异常振动导致的加速度超标或失真,避免了误判。
