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 enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.
[0023] With the rapid development of automatic driving technology of electric vehicles, it becomes easier and more convenient for drivers to drive smart vehicles. Among them, the adaptive cruise control system (Adaptive Cruise Control, ACC), as the basic function of vehicle automatic driving, is currently widely deployed in vehicles. This system can effectively relieve driving fatigue, improve vehicle driving safety and increase road traffic flow. The basic principle of the system is: use the on-board sensor to perceive the state of the vehicle and the traffic flow, combine the driver's driving operation on the vehicle, and use the control algorithm to automatically control t...

The embodiment of the invention discloses a vehicle cruise control method and device, a vehicle and a storage medium, and relates to the technical field of automatic driving. The method comprises thesteps that when a vehicle is in an automatic cruise mode, a speed limiting area in the driving direction of the vehicle is obtained; a speed limit value corresponding to the speed limiting area and the current speed of the vehicle are obtained; when the current vehicle speed exceeds the speed limit value, the current distance between the vehicle and the speed limiting area is obtained; and when the current distance meets a preset condition, the vehicle speed of the vehicle is adjusted so that the vehicle speed of the vehicle entering the speed limiting area is controlled not to exceed the speed limit value, and the average speed of the vehicle passing through the speed limiting area is controlled not to exceed the speed limit value. According to the invention, the situation of overspeed violation and traffic accidents can be effectively avoided, and the vehicle passing efficiency is improved.
Description
technical field [0001] The present invention relates to the technical field of automatic driving, and more specifically, to a vehicle cruise control method, device, vehicle and storage medium. Background technique [0002] With the rapid development of automatic driving technology, more and more vehicles are now equipped with cruise control systems. Cruise control systems are systems that use electronic control technology to keep cars running at constant speeds automatically. Its main function is to lock the speed of the vehicle according to the driver's needs. It can automatically maintain a fixed speed without stepping on the accelerator pedal. When driving on the expressway, the driver can effectively reduce physical fatigue and the vehicle can run at a constant speed. It also saves fuel consumption. [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, th...
