Abstract

The invention provides a wake-up monitoring method and device and an electric automobile, and relates to the technical field of automobiles. The method comprises the following steps: acquiring a network message sent after an electronic control unit is awakened; wherein the network message comprises a wake-up indication bit, and the wake-up indication bit indicates that the electric control unit is in an active wake-up state or a passive wake-up state; generating a network management message according to the network message; the network management message comprises a preset byte corresponding to the electric control unit, and the preset byte is used for recording a numerical value in the wake-up indication bit; and sending the network management message to a remote information processor. According to the technical scheme, firstly, network messages of a plurality of electronic control units are sorted and gathered, secondly, the network management messages are high in applicability, the types of the network messages are not distinguished, and thirdly, the fault electronic control units can be positioned through the network management messages.

Description

technical field [0001] The present invention relates to the technical field of automobiles, in particular to a wake-up monitoring method, device and electric vehicle. Background technique [0002] At present, the method of waking up the electronic control unit of the vehicle in the prior art can already monitor the sleep and wake-up state of the electronic control unit of the vehicle in the background, which brings convenience for troubleshooting the problem of power shortage. However, it still faces the problem that abnormal wake-up cannot be located, that is, it is impossible to determine which electronic control unit wakes up the whole vehicle, which increases the complexity of subsequent troubleshooting and leads to low efficiency in subsequent troubleshooting. SUMMARY OF THE INVENTION [0003] The embodiment of the present invention provides a method for monitoring and awakening an electronic control unit of a vehicle, so as to solve the problem that the current elect...
