101. when the vehicle speed is detected to be smaller than a first threshold value, acquiring state information of an ignition switch accessory ACC and vehicle body state information;
in life, some careless drivers often get off without pulling the hand brake, and the resultant car is damaged by people; according to the relative position of the vehicle and the slope, some vehicles slide forwards, and some vehicles slide backwards; some vehicles do not flameout, but only the driver does not pull the hand brake to leave the driver position temporarily; after some vehicles are flamed out, the drivers forget to pull the hand brakes, the vehicles automatically start to slide when the drivers do not get off the vehicles completely, in order to improve the safety of parking, the locking of the parking hand brakes needs to be prompted, and therefore the conditions of getting off the vehicles by the drivers need to be recognized.
In practical application, since the driver's action of getting off the vehicle may be completed quickly, in order to reduce the recognition time for recognizing the driver's time for getting off the vehicle and reduce the recognition delay, in the embodiment of the present invention, data is obtained in advance, before the vehicle speed is decelerated to zero, when the vehicle speed is detected to be less than a first threshold value, state information of the ignition switch accessory ACC and vehicle body state information are obtained, the vehicle body state information at least includes handbrake state information, seat belt state information and front left door state information, a specific information obtaining manner may be that information required for targeted detection and obtaining by installing a corresponding detection device on the vehicle body, for example, a targeted device is used to detect the voltage of the corresponding detection device to determine the state of the ACC, or an existing device of the vehicle body ACC, for example, the handbrake state information, the seat belt state information and the front left door state information may be obtained based on the vehicle body bus, the specific manner of acquiring the state information of the ACC and the vehicle body state information is not limited herein.
It is understood that the first threshold in the embodiment of the present invention is a value greater than zero, for example, 10km/h, 5km/h, and the like, and may be specifically set according to a requirement of a user, and is not limited herein.
102. Judging whether the ACC is in a flameout state;
when the vehicle speed is less than the first threshold value, the state of the ACC can reflect whether the driver has the tendency of getting off the vehicle to a certain extent, if the ACC is in a flameout state, the possibility that the driver gets off the vehicle is high, and whether reminding is needed or not can be judged by combining the state of the hand brake; if the ACC is not in a flameout state, the driver may get off temporarily, and it is necessary to further determine whether the driver is away or inclined to leave from more dimensions.
103. Judging whether the hand brake is in an unlocked state;
the state of the hand brake can determine whether to remind the driver, if the hand brake is in a locked state, the driver obviously does not need to be reminded, and if the hand brake is in an unlocked state, the driver needs to be further judged from more dimensions whether to leave or have a tendency to leave.
104. Executing a first early warning operation;
if the ACC is in a flameout state, the possibility of getting off the vehicle by the driver is very high, when the handbrake is in an unlocked state, a first early warning operation is executed, the specific first early warning operation comprises voice reminding, video reminding or text reminding, for example, a prompt voice can be played and a warning picture video can be displayed based on a vehicle-mounted navigation system, the first early warning operation can be connected to a background of software through a network, a short message or a WeChat prompt can be sent out from the background, the specific early warning mode can be reasonably set according to the requirements of users, and the specific early warning mode is not limited here.
105. Judging whether the safety belt is in a release state;
if the ACC is not in a flameout state, the driver has the possibility of getting off temporarily, whether the safety belt is in a release state or not can be judged, and whether the driver leaves or has the tendency of leaving can be judged according to the state of the safety belt.
106. Judging whether the front left vehicle door is in an open state or not;
if the ACC is not in a flameout state, the driver has the possibility of getting off temporarily, whether the front left door is in an open state or not can be judged, and whether the driver leaves or tends to leave can be judged by combining the state of the front left door. If the ACC is not in a flameout state, if the front left door is not opened, the possibility that the driver gets off the vehicle is low, and the early warning operation is not executed.
107. Executing a second early warning operation;
if the ACC is in a non-flameout state and the safety belt is in a release state, the driver has a tendency to get off temporarily, and when the hand brake is in an unlocked state, a second early warning operation is executed.
If the ACC is in a non-flameout state, the safety belt is in a non-release state, the front left door is in an open state, the driver has a tendency to get off temporarily, and when the hand brake is in an unlocked state, a second early warning operation is executed.

207. Judging whether the driver seat is occupied or not;
if the ACC is not in a flameout state, the driver also has the possibility of getting off temporarily, whether the driver is in the driver seat or not can be judged, and whether the driver leaves or not can be judged by combining the state of the driver seat. If the driver is not occupied, other operations may be performed, for example, the driver may be reminded in a short message or a WeChat mode, or the driver may not be reminded, and the process is ended, which is not limited herein.
Specifically, whether the driver seat is occupied or not can be identified through a pressure sensor on a driver seat in the vehicle, and whether the driver seat is occupied or not can also be identified through a human body infrared sensor, a camera and the like, and a specific identification mode is not limited here.
