Whole vehicle network abnormal sleep wake-up monitoring method and device and storage medium

Abstract

The invention relates to a whole vehicle network abnormal sleep wake-up monitoring method and device and a storage medium. The monitoring method comprises the steps that a monitoring controller is configured; the monitoring controller obtains a network management message of each controller in a monitoring network; and the monitoring controller monitors an abnormal sleep fault and an abnormal wake-up fault based on the network management message, and records and stores the abnormal sleep fault and the abnormal wake-up fault to form abnormal monitoring data; furthermore, the controller with the abnormal sleep fault and the abnormal wake-up fault is checked based on the abnormal monitoring data. Compared with the prior art, monitoring and troubleshooting are carried out through a software scheme, so that the efficiency is high, and meanwhile, faults can be accurately and reliably positioned.

Description

technical field [0001] The invention relates to the technical field of vehicle fault monitoring, in particular to a monitoring method, device and storage medium for abnormal sleep and wake-up monitoring of a vehicle network. Background technique [0002] With the development of science and technology, automobiles, as cutting-edge products of industrialization, have entered thousands of households, and the performance of automobiles is naturally valued by consumers and R&D personnel. The most basic requirement for a car is to be able to start and drive normally and achieve physical displacement. However, if the vehicle battery loses power, the vehicle will not be able to start and drive normally. It can be seen that vehicle power loss is a very serious problem. [0003] The energy source on the vehicle mainly comes from the chemical energy of gasoline combustion, which is converted into mechanical energy to drive the vehicle, and at the same time, part of the mechanical ene...

AI Technical Summary

Problems solved by technology

[0005] 1. The chemical reaction of the battery itself needs to consume a certain amount of energy. When the vehicle is left standing for too long (more than 60 days), the energy of the battery will be lost;

[0006] 2. The user operates the vehicle abnormally, such as using the electrical appliances on the vehicle without the engine running for a long time, resulting in energy loss of the battery;

[0007] 3. The generator is damaged and cannot work normally to charge the battery, resulting in energy loss of the battery;

[0008] 4. The battery itself is aging, unable to store electric energy and cannot provide energy;

[0009] 5. After the vehicle is locked, some controllers cannot sleep, causing the static current of the vehicle to be too large, resulting in energy loss of the battery;

[0010] 6. Other reasons lead to battery energy loss;

This method is simple and effective, but the workload is huge
