A vehicle safety driving early warning method based on an internet of vehicles

Abstract

The invention discloses a vehicle safety driving early warning method based on an internet of vehicles. The method comprises the following steps: a vehicle-mounted central processing unit in a vehicle-mounted end sends target information of the current moment every an interval of T1 time; a network background server judges whether the road section, where vehicles locate at the current moment, has dangerous points; and the network background server sets vehicle voice caution, and provides an avoidance path to a vehicle-mounted display screen according to a road early warning system in a fire safety system of a three-dimensional map. The method, based on the fire safety system of the three-dimensional map, provides an early warning mode for vehicle safety driving, can carry out road early warning by obtaining road disaster of the fire safety system of the three-dimensional map and select an optimum path to avoid the disaster, thereby improving road barrier-free flow, and realizing information interaction oriented to the vehicle-mounted end for vehicle safety driving early warning and the network background server.

Description

technical field [0001] The invention belongs to the technical field of vehicle safety, in particular to a vehicle safety driving early warning method based on the Internet of Vehicles. Background technique [0002] 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 cannot obtain reliable danger information. On the other hand, if the on-board hazard warning system lacks interaction with network inf...

[0002] 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
