The invention discloses a fault diagnosis method and device, a vehicle control unit and a nonvolatile storage medium. The method comprises the steps that a control signal between a heat management component and a vehicle control unit is collected, and the heat management component and the vehicle control unit are located in a target vehicle; analyzing the control signal to obtain a signal parameter of a low-level signal in the control signal; and determining the fault state of the thermal management component according to the signal parameter of the low-level signal. The technical problem that the hardware cost required for diagnosing whether the thermal management component in the vehicle breaks down or not is high is solved.
本发明公开了一种故障诊断方法、装置、整车控制器以及非易失性存储介质。其中,该方法包括:采集热管理部件与整车控制器之间的控制信号,其中,热管理部件和整车控制器位于目标车辆中;分析控制信号,得到控制信号中的低电平信号的信号参数;根据低电平信号的信号参数,确定热管理部件的故障状态。本发明解决了诊断车辆中的热管理部件是否发生故障所需的硬件成本较高的技术问题。
