Problems solved by technology
[0003] However, the current vehicle cruise control system is applicable to a single road environment and cannot be applied to more complex road conditions. For example, there are various speed limit nodes on the road or road conditions where the speed limit is required at the entrance of the vehicle. At this time, the driver needs to intervene in the driving. , if the intervention is not timely, it may cause violations or traffic accidents, so that driving safety and better user experience cannot be guaranteed

Embodiment Construction
[0022] In order to better understand the invention, the technical solutions in the embodiments of the present invention will be described in contemplation in the following to the accompanying drawings in the embodiments of the present invention.
[0023] With the rapid development of automatic driving technology, the driver becomes more relaxed and convenient when driving smart vehicles. Among them, Adaptive Cruise Control, ACC) is used as the basic function of vehicle automatic driving, which is currently being widely configured in vehicles, which can effectively alleviate driving fatigue while improving vehicle safety and increased roads. Pass traffic. The basic principle of the system is to use the car sensor to perceive the motorcycle and traffic flow, combined with the driver's driving operation, using the control algorithm to automatically control the drive system and brake system of the vehicle, so that the vehicle keeps the desired portrait Motion status, implementing func...

The embodiment of the invention discloses a vehicle cruise control method, device, vehicle and storage medium, and relates to the technical field of automatic driving. The method includes: when the vehicle is in the automatic cruise mode, acquiring a speed limit area in the driving direction of the vehicle; acquiring a speed limit value corresponding to the speed limit area and the current vehicle speed of the vehicle; when the current vehicle speed When the speed limit value is exceeded, the current distance between the vehicle and the speed limit area is obtained; when the current distance satisfies a preset condition, the vehicle speed of the vehicle is adjusted to control the speed of the vehicle The vehicle speed when entering the speed limit area does not exceed the speed limit value, and the average speed of the vehicle passing through the speed limit area is controlled not to exceed the speed limit value. The invention can effectively avoid the occurrence of speeding violations and traffic accidents, and improve the traffic efficiency of vehicles.
Description
Technical field [0001] The present invention relates to the field of automatic driving techniques, and more particularly to a vehicle cruise control method, a device, a vehicle, and a storage medium. Background technique [0002] With the rapid development of automatic driving technology, there is now a cruise control system on more and more vehicles, and the cruise control system is a system that maintains automatic car automatic car automatic use with electronic control technology. Its main function is to lock the vehicle speed of the vehicle according to the driver's needs. You can automatically keep a fixed speed driving without stepping on the throttle. When traveling on the highway, the driver can effectively reduce the fatigue of the body, while the vehicle is driving It can also save fuel consumption. [0003] However, the road environment for the cruise control system of the vehicle is more complete, and it is not possible to reference more complicated road conditions. F...
