Early warning method against vehicle collision based on electronic map

Abstract

The invention relates to an early warning method against vehicle collision based on an electronic map. The method comprises that 1) GPS data, which comprises movement station information and position information, of a vehicle is obtained, and the position information of the vehicle is converted by a coordinate system and mapped into a two-dimensional rectangular coordinate system; 2) according to historical GPS data of the vehicle, the present position information of the vehicle is optimized in a Kalman filtering algorithm to predict a first present position of the vehicle; 3) according to the historical GPS data of the vehicle, information of the electronic map is combined to predict a second present position of the vehicle; 4) the first present position and the second present position of the vehicle are combined to predict the optimal position of the vehicle; and 5) the predicted optimal position of the vehicle is combined with a TCC algorithm to make early warning against collision. Compared with the prior art, whether the vehicle possibly collides with vehicles in the surrounding is predicted in real time, early warning is given to a driver in real time, the driving safety and the vehicle positioning precision are effectively improved, and the method is practical and efficient.

Description

Technical field [0001] The present invention relates to intelligent transportation technology in the Internet of Vehicles, in particular to a vehicle collision warning method based on an electronic map. Background technique [0002] The Internet of Vehicles is an important application of the Internet of Things in the field of intelligent transportation. Through information interaction, it connects cars, roads and pedestrians into a whole network, thereby achieving intelligent transportation. In terms of driving safety and intelligent transportation, the Internet of Vehicles is mainly based on vehicle-to-vehicle communication and vehicle-to-road communication to reliably share information in real time, thereby improving the efficiency of traffic flow and driving safety. Based on vehicle-to-vehicle communication or vehicle-to-vehicle communication, combined with vehicle-mounted GPS and electronic map information, the vehicle-mounted active safety system can inform the driver of pos...
