Embodiment 1

[0244] The current network is divided into network segments and each network segment is connected through a gateway.

[0245] The structure of the message is shown in Table 6 below: byte 0 of the wake-up source node stores the active wake-up ID, byte 0 of other nodes stores the source node ID, byte 1 stores control information, byte 4 stores the cause of active wake-up, byte 5 stores the active wake-up flag bit, node 6 stores the reason for being woken up, and byte 7 stores the wake-up ID.

[0246]

[0247] Table 6

[0248] When the network wakes up, the message sent by the node in the network will be stored. Specifically, the message can be stored according to the storage method of the message or the message similar to the message in the prior art.

[0249] When the first wake-up fault needs to be detected, the message to be detected is extracted from the stored message, and for each network wake-up, the message sent by the node in the network during the network wake-up i...

Abstract

The invention discloses a wake-up fault detection method, which comprises the following steps that: messages for detecting a first wake-up fault are collected, and each message comprises a wake-up node indication parameter and a first wake-up reason parameter; determining a wake-up source node according to a wake-up node indication parameter in the collected message; and judging whether the determined value of the first wake-up reason parameter in the message sent by the wake-up source node meets a preset normal wake-up numerical value condition, If not, determining that a first wake-up fault occurs. According to the method and the device, the message in which the wake-up node indication parameter and the first wake-up reason parameter are newly defined is collected, the wake-up source node is determined according to the wake-up node indication parameter, and whether the wake-up source node belongs to abnormal wake-up is judged according to the first wake-up reason parameter, so that a technical scheme for troubleshooting abnormal wake-up faults is provided.

Description

technical field [0001] The present invention relates to the field of vehicle network technology, in particular to a wake-up fault detection method, device, terminal and storage medium, and message sending method, device and electronic control unit. Background technique [0002] AUTOSAR (AUTomotive Open System Architecture, automotive open system architecture) realizes the management of network sleep and wake-up through network management messages (hereinafter referred to as messages). [0003] The structure of the message is shown in Table 1 below: byte 0 stores the address of the ECU (Electronic Control Unit, electronic control unit or node or controller, hereinafter collectively referred to as node) that sends the message, and byte 1 stores It is control information, and byte 2 to byte 7 are reserved spaces set to meet user-defined requirements. [0004] [0005] Table 1 [0006] The bit structure of byte 1 is shown in Table 2 below: Bit 1 to bit 7 are reserved bits, ...
