Vehicle speed control method, device and system for Internet of Vehicles

Abstract

The invention provides a vehicle speed control method, device and system for the Internet of Vehicles, and the method comprises the steps: obtaining the equipment information of first roadside equipment currently connected with a target vehicle and second roadside equipment adjacent to the first roadside equipment at the same side of the first roadside equipment, the physical distance between thetwo roadside equipment and the switching duration according to the state information of the target vehicle; therefore, the vehicle speed control range of the target vehicle meeting the switching control condition is obtained by utilizing the obtained parameters, so that the computer equipment responds to the roadside equipment switching request for the target vehicle and controls the target vehicle to switch the communication connection between the two adjacent roadside equipment while controlling the switching of the communication connection between the two adjacent roadside equipment. The running speed of the target vehicle is regulated and controlled according to the vehicle speed control range, it is guaranteed that the target vehicle has enough time to be in the signal overlapping area between the two adjacent roadside devices, communication connection switching between the target vehicle and the two roadside devices is completed, and the vehicle is prevented from disappearing inthe switching process.

Description

technical field [0001] The present application relates to the application field of the Internet of Vehicles, in particular to a vehicle speed control method, device and system for the Internet of Vehicles. Background technique [0002] The Internet of Vehicles (IoV) refers to the Internet of Vehicles, which uses the moving vehicle as the object of information perception. With the help of a new generation of information and communication technology, it realizes all-round network links between vehicles and cloud platforms, vehicles and vehicles, vehicles and roads, vehicles and people, and inside vehicles. , improve the overall intelligent driving level of the vehicle, provide users with safe, comfortable, intelligent, and efficient driving experience and traffic services, and at the same time improve traffic operation efficiency and reduce traffic accidents. [0003] At present, with the development of intelligent traffic management and Internet of Vehicles technology, the ro...

Problems solved by technology

[0004] Among them, when the vehicle passes through the junction area of ​​two adjacent RSUs, the vehicle-mounted terminal OBU needs to disconnect the RSU of the current communication connection, and switch to the next RSU communication connection adjacent to the vehicle's driving direction. During the switching process, In order to avoid "vehicle missing", that is, the vehicle's on-board terminal OBU and RSU lose contact, the existing technology usually controls the vehicle to drive through the junction area between two adjacent RSUs at the maximum speed specified by the road, which is very dangerous and cannot reliably avoid "vehicle loss".
