The invention discloses an automobile fault sending method and device, an electronic control unit and a storage medium, is applied to the technical field of electric automobiles, and solves the technical problem that: the most serious fault cannot be guaranteed to be known by a system in the first time in the prior art, and the safety performance of a whole automobile is reduced. The method provided by the invention is applied to an electronic control unit (ECU). The method comprises the following steps: receiving fault signal codes which are reported by a whole vehicle and have a one-to-one correspondence relationship with specific faults and trigger time of the corresponding faults, and pre-arranging the corresponding relationship between the fault signal codes and the faults according to the severity of the corresponding faults; storing the fault signal code and the trigger time of the corresponding fault; acquiring a plurality of fault signal codes and trigger time of corresponding faults from the stored fault signal codes according to a rule that the higher the severity is, the more preferential the fault signal codes are in every preset time period; and sending the obtained fault signal codes and the triggering time of the corresponding faults to a receiving device through different CAN signals.

    本发明公开了一种汽车故障发送的方法、装置、电子控制单元及存储介质,应用于电动汽车技术领域,解决现有技术无法保证最严重的故障在第一时间被系统获知使得整车的安全性能降低的技术问题。本发明提供的方法应用于电子控制单元ECU,该方法包括:接收整车上报的与具体故障具有一一对应关系的故障信号编码及对应故障的触发时间,该故障信号编码与该故障的对应关系按照对应故障的严重程度预先编排;存储该故障信号编码及对应故障的触发时间;每间隔预设的时间周期,按照严重程度越高越优先的规则从存储的该故障信号编码中获取若干个故障信号编码及对应故障的触发时间;将获取的该故障信号编码及对应故障的触发时间通过不同的CAN信号发送至接收设备。
