Vehicle safety driving early warning method based on vehicle internet

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...

Problems solved by technology

[0004] Danger warning technology is one of the key technologies for vehicle active safety, and the existing vehicle anti-collision warning system, lane departure warning system, dangerous blind spot detection system and other vehicle active safety warning systems mostly use video image analysis technology, ultrasonic detection technology, radar Detection technology or infrared detection technology perceives the dangerous state of vehicles and roads within a short distance, so as to realize the vehicle's autonomous danger warning and safety control functions; Without the interference of the aforementioned detection technology, the vehicle will not be able to obtain reliable hazard information

On the other hand, if the on-board hazard warning system lacks interaction with network information, the vehicle cannot perform real-time data transmission with the remote traffic control center, and the hazard warning function cannot be organically combined with functions such as remote data communication, vehicle positioning and navigation, and the vehicle becomes a Information islands cannot perceive the danger information and geographical location information in the large-scale driving area in advance, which will inevitably weaken the reliability of the vehicle's autonomous danger warning function, and also reduce the vehicle's active safety control capability
