Example Embodiment

[0049] Example one

[0050] In the embodiment of the present invention, the mutual relationship between vehicles and the intermolecular interaction force are compared, and the increase and decrease of the distance between vehicles are described as the result of repulsive force and attractive force. Modeling of vehicle mobility and defining related parameters.

[0051] The embodiment of the present invention provides a processing flow of a vehicle speed control method based on the Internet of Vehicles. figure 1 As shown, including the following steps:

[0052] Step S110: The vehicle-mounted controller of the vehicle performs two-way communication with the server through the Internet of Vehicles, and the server stores the received operating state information of each vehicle in the vehicle state information database.

[0053] A server is set up on the road section where vehicle speed control is required, and the server and the on-board controller of each car driving on the road section s...

Example Embodiment

[0077] Example two

[0078] This embodiment provides a vehicle speed control system based on the Internet of Vehicles. The structure diagram of the system is as image 3 As shown, it includes the following modules: a server 31 and a vehicle controller 32;

[0079] The server 31 is configured to be set in a road section where vehicle speed control is required, and calculate the distance between the vehicle and the preceding vehicle in the road section based on the Internet of Vehicles;

[0080] The vehicle-mounted controller 32 is configured to be installed in the vehicle and calculate the interaction between the vehicle and the preceding vehicle based on the distance between the vehicle and the preceding vehicle and the speed of the vehicle Force; according to the interaction force between the vehicle and the preceding vehicle speed control of the vehicle.

[0081] Further, the vehicle-mounted server 32 is used to support the Internet of Vehicles, communicate with the server through ...

Abstract

The embodiment of the invention provides a vehicle speed control method and system based on the internet of vehicles. The method mainly includes the steps of calculating the distance between a vehicle and a vehicle in the front on the basis of the internet of vehicles, calculating the mutual action force between the vehicle and the vehicle in the front according to the distance between the vehicle and the vehicle in the front and the speed of the vehicle, and controlling the speed of the vehicle according to the mutual action force of the vehicle and the vehicle in the front. Analogy is conducted on the relation between the vehicles and the intermolecular force on the basis of the mutual action force, calculated on the basis of the internet of vehicles, between the vehicle and the vehicle in the front, the near-distance repulsive force and the long-distance attraction force which are represented by the intermolecular force are quite similar to the actual approaching process and the actual separating process of the vehicle and the vehicle in the front, and therefore a new vehicle mobility model modeling method and thought are put forward, and the advancing speed of the vehicles are controlled according to the mutual action force between the vehicles.

Description

technical field [0001] The present invention relates to the field of Internet of Vehicles, in particular to a vehicle speed control method and system based on Internet of Vehicles. Background technique [0002] The Internet of Vehicles is a huge interactive network composed of information such as vehicle location, speed, and route. It can make the driving of vehicles more efficient and orderly, and can realize intelligent management of traffic. The Internet of Vehicles is a typical application of the Internet of Things in the transportation field. At present, there have been many studies on the Internet of Vehicles. Although it is critical to test and evaluate vehicle-to-vehicle and vehicle-infrastructure network applications in a real test environment, simulation is the best way to validate network protocols for vehicle applications due to logistical difficulties, economical issues, and technical limitations. choose. When designing the simulation environment, it is necess...
