Abstract

The present invention provides a detection method, device and system for abnormal wake-up of a vehicle. The detection method for abnormal wake-up of a vehicle includes: receiving a fault signal sent by the vehicle, wherein the fault signal is that the output voltage of the low-voltage storage battery of the vehicle is low Sent at a preset voltage threshold; according to the fault signal, multiple sets of pre-stored vehicle data are obtained, wherein each set of vehicle data is reported each time the vehicle wakes up; if there are at least two sets of vehicle data If the amount of data is less than the preset threshold, an abnormal wake-up reminder message is generated; the present invention determines whether the vehicle has abnormal wake-up through the vehicle data, and reminds the user when the vehicle has abnormal wake-up, thereby avoiding multiple power feeding of the low-voltage battery.

Description

technical field [0001] The invention relates to the field of vehicle wake-up, in particular to a detection method, device and system for abnormal wake-up of a vehicle. Background technique [0002] The vehicle is in a power-off state before starting, so it is necessary to wake up the vehicle before using it. Under normal circumstances, during the wake-up process of the vehicle, all controllers will go through the sleep state, standby state and working state in turn. When the controller is in the working state, the vehicle can be driven by the whole vehicle, and the low voltage in the vehicle will not be affected during this process. damage to the battery. [0003] If the vehicle wakes up abnormally, only part of the controllers can be in the working state during the wake-up process, and when the working conditions are not met, the controllers will enter the dormant state again, which will cause the low-voltage battery to feed, and the low-voltage battery will feed multiple ...
