Step 202: and sending first indication information to an AI voice broadcast device under the condition that the first expiratory alcohol concentration is greater than or equal to a preset alcohol concentration, wherein the first indication information is used for indicating the AI voice broadcast device to broadcast warning information.
When the breath alcohol concentration is greater than or equal to 20mg/100ml and less than 80mg/100ml, drunk driving is realized, and when the breath alcohol concentration is greater than 80mg/100ml, drunk driving is realized, so that the preset alcohol concentration can be less than or equal to 20mg/100 ml.
And if the first breath alcohol concentration is greater than or equal to the preset alcohol concentration, the driver is represented to drunk driving.
Wherein, the warning information that the AI voice broadcast device reported can be predetermined.
The first indication information can carry a first breath alcohol concentration of a driver, the range of the first breath alcohol concentration is different, and the corresponding warning information is different.
Wherein the first indication information is preset.
Step 203: and under the condition that the first breath alcohol concentration is smaller than the preset alcohol concentration, acquiring a running track and a running speed of the current vehicle in a first time period, wherein the starting moment of the first time period is the moment when the first breath alcohol concentration is determined to be smaller than the preset alcohol concentration.
And if the first breath alcohol concentration is less than the preset alcohol concentration, the driver is represented to drive the vehicle without wine.
Wherein the duration of the first period may be preset.
The duration of the first time period may be 5 minutes, 8 minutes, or other durations.
Step 204: determining that the driver is currently in a fatigue driving state based on the travel track and the travel speed.
If the driving track and the driving speed both meet the preset conditions, it is determined that the driver is not in the fatigue driving state currently, and if the driving track or the driving speed does not meet the preset conditions, it is determined that the driver is in the fatigue driving state currently.
Step 205: performing fatigue driving intervention on the driver.
The driver can be intervened in fatigue driving by broadcasting warning information through an AI voice broadcasting device, contacting with terminal equipment associated with the current vehicle, directly dialing an alarm call, and the like.

If the first pressure value is larger than or equal to the preset pressure value, the driver is located in the current vehicle.
And if the driver is positioned in the current vehicle and the current vehicle is in a running state, detecting the breath alcohol concentration of the driver by adopting an alcohol concentration detection device.
It can be seen that, in the embodiment of the application, the pressure value of the driving position is detected and the state of the vehicle is monitored, which is beneficial to avoiding inconvenience in vehicle use brought to a driver.

The number of the associated devices may be one or more.
In a possible implementation manner, the second indication information carries the second breath alcohol concentration, and the associated device is contacted based on an alcohol concentration range in which the second breath alcohol concentration is located.
For example, if the second alcohol concentration is within (20mg/100ml,40/100ml), the associated device is a parent device, and if the second alcohol concentration is greater than 40mg/100ml, the associated device is a police device.
It can be seen that in the embodiment of the application, whether the driver is in the drunk driving state or not is judged again after the preset time length, so that the vehicle accidents caused by drunk driving of the driver after the AI voice broadcasting device broadcasts the warning are avoided.
