Abstract

The invention discloses a vehicle safety driving early warning method based on vehicle internet. Vehicle information data is sent to a network background server through a vehicle-mounted wireless communication unit, the network background server acquires information data of dangerous points on a road section where a vehicle is located according to the vehicle information data and sends the information data at the dangerous points on the road section to the vehicle-mounted wireless communication unit, a vehicle-mounted central processing unit compares obtained dangerous point information with self-vehicle information, a safety distance model is called to generate early warning parameters, and a vehicle-mounted alarm unit, a vehicle-mounted display unit and an electronic control braking system are controlled to perform early warning response. The vehicle safety driving early warning method based on the vehicle internet has the advantage that a network background server terminal provides the dangerous point information for a vehicle-mounted terminal, the vehicle-mounted terminal acquires and analyzes vehicle geographical position information and the dangerous point information on the road section where the vehicle is located in real time, the vehicle-mounted alarm unit, the vehicle-mounted display unit and the electronic control braking system are controlled to perform the early warning response, and the vehicle safety driving early warning method based on the vehicle internet has reliability and high efficiency of vehicle network data communication.

Description

technical field

[0001] The invention relates to the technical field of intelligent traffic system and wireless communication, in particular, it is a vehicle safety driving early warning method based on Internet of Vehicles. Background technique

[0002] In recent years, my country's transportation industry has developed vigorously, and the number of residents' car ownership has increased significantly. The subsequent road traffic problems have occurred frequently. Traffic accidents such as vehicle rear-end collisions and rollovers have increasingly attracted the attention of the government and society. Safety has become the focus of attention in the transportation technology field.

[0003] With the rapid development of wireless data communication and mobile computing technology, network mobile terminals are extended to be applied to vehicle platforms. Based on advanced wireless communication technology and Internet of Vehicles technology, efficient data transmission and inf...

Examples

Embodiment Construction

[0068] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0069] The vehicle safety driving early warning method based on the Internet of Vehicles of the present invention, such as figure 1 As shown, it is realized through the following steps:

[0070] Step 1: The vehicle terminal sends vehicle information to the network server;

[0071] The vehicle-mounted central processing unit in the vehicle-mounted terminal sends the current vehicle information to the network background server every T1 interval through the vehicle-mounted wireless communication unit, including the geographic latitude and longitude data of the vehicle (obtained by the GPS communication unit), driving speed data (obtained by the wheel speed sensor ), the port number of the wireless communication unit, and at the same time send the date and time of the current moment to the network background server (that is, the date and time when the vehicle ce...
