For example, the pressure detection device uniformly sets at least twelve pressure detection points at one to twelve o' clock positions on the steering wheel of the vehicle, when the steering wheel is held by a driver with one hand, the vehicle can acquire pressure information of the steering wheel held by the driver with one hand through the pressure detection device, and when the steering wheel is held by the driver with both hands, the steering wheel information of the steering wheel held by both hands of the driver can be acquired through pressure monitoring on the pressure detection device.
Whether the driver is paying attention to driving the vehicle is detected by the in-vehicle fatigue driving detection system.
Specifically, the determining to send out the voice reminding information according to the information of the hands and the steering wheel of the driver includes:
judging information of hands and steering wheels of a driver;
wherein, when it is determined that the driver's both hands and the steering wheel information satisfy at least two conditions: the camera device detects that the hands of the driver leave the steering wheel, the pressure detection device detects that the hands of the driver do not hold the steering wheel, and the fatigue driving detection system detects that the attention of the driver is not focused on driving the vehicle;

Specifically, under the condition that the hands of the driver leave the steering wheel, the steering wheel is locked, the driver is not allowed to intervene, and the driving speed is adjusted according to the driving distance detection result. The vehicle front side detection module detects a front vehicle distance between a vehicle and a front vehicle; the vehicle rear side detection module detects a rear vehicle distance between a vehicle and a rear vehicle. When the front vehicle distance is greater than the front vehicle set distance and the rear vehicle distance is greater than the rear vehicle set distance, the vehicle starts an automatic driving mode. When the current vehicle distance is smaller than or equal to the set distance of the front vehicle and the rear vehicle distance is smaller than or equal to the set distance of the rear vehicle; the driving speed is adjusted to enable the distance between the front vehicle and the rear vehicle to be larger than the set distance between the front vehicle and the set distance between the rear vehicle.
For example: the distance is set to be 20 meters, and when the front vehicle distance is detected to be more than 20 meters and the rear vehicle distance is detected to be more than 20 meters, the vehicle automatic driving module is started, and the vehicle enters an automatic driving state. When the detected vehicle distance between the front vehicles is less than or equal to 20 meters, the detected vehicle distance between the rear vehicles is less than or equal to 20 meters; the vehicle speed control module adjusts the vehicle speed through braking or acceleration, so that the vehicle keeps the front vehicle distance and the rear vehicle distance larger than 20 meters.
