Vehicle anomaly detection method, device and equipment and storage medium

Abstract

The invention belongs to the technical field of vehicle detection, and discloses a vehicle anomaly detection method, device and equipment and a storage medium. The method comprises the steps that after a vehicle is powered off, ECU nodes of the vehicle are detected, and node information corresponding to abnormal non-dormant nodes is obtained, the abnormal non-dormant node is diagnosed according tothe node information, message data of the CAN network within preset time is obtained according to the abnormal time of the abnormal non-dormant node, then the message data, the node information and the diagnosis information are sent to a cloud server, the cloud server feeds back corresponding processing information according to the message data, the node information and the diagnosis information,and exception processing on the vehicle is performed according to the processing information. By means of the mode, the vehicle-mounted terminal monitors the whole vehicle non-dormancy ECU nodes, reports the whole vehicle non-dormancy ECU nodes to the Internet of Vehicles background in real time, carries out automatic processing according to different abnormal non-dormancy conditions of differentECUs, avoids excessive power consumption of the vehicle, and solves the problem that the ECUs are not dormant abnormally in time.

Description

technical field [0001] The present invention relates to the technical field of vehicle detection, in particular to a vehicle abnormality detection method, device, equipment and storage medium. Background technique [0002] As one of the most important units of a car, ECU plays a dominant role in the use of the car. ECU (Electronic Control Unit) electronic control unit is also called "driving computer", "vehicle computer" and so on. The ECU sleep and wake-up functions are very important in the ECU. Most ECUs in cars need long-term power supply. In order to reduce power consumption when the car is not in use, the ECU needs to enter a sleep state to reduce power consumption. When some specific events occur, such as the door is opened, there is a remote control signal, etc., the ECU needs to wake up from the sleep state immediately to respond. ECUs with relatively simple functions can be designed to be in deep sleep, so that wake-up events can generate interrupts to wake up the...
