Abstract

The invention provides a detecting method, device and system for vehicle abnormal wakeup. The detecting method for vehicle wakeup comprises the steps that a fault signal sent by a vehicle is received,wherein the fault signal is sent when the output voltage of the vehicle is lower than a preset voltage threshold value; a plurality of groups of pre-stored vehicle data are obtained according to thefault signal, wherein the groups of the vehicle data are reported every time the vehicle is waken up; and if at least two groups of the vehicle data are lower than the preset threshold value, abnormalwakeup reminding messages are generated. According to the detecting method, device and system for vehicle abnormal wakeup, whether abnormal wakeup occurs to the vehicle or not is determined through the vehicle data, when abnormal wakeup occurs to the vehicle, users are reminded, and multiple times of feeding of a low-pressure storage battery is avoided.

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 ...
