Abstract

The invention discloses a vehicular access synergism anti-collision pre-warning system based on V2X. Aiming at judgment links of an anti-collision pre-warning decision in the beyond visual range of anintelligent connected vehicle, in combination with a V2X communication technology and an inertial navigation technology, an improved safe distance model is designed, and an anti-collision pre-warningsystem of the intelligent connected vehicle is constructed. A V2X communication module is mainly used for being responsible for data communication, including data broadcasting of the vehicle, detection of data of surrounding vehicles, and receiving of roadside end road traffic information; a positioning module comprises a GPS/BD sensor for obtaining position data of the vehicle, including the data of longitude and latitude, course angle, speed, elevation and the like; the sensors such as a posture data module, an accelerometer and a gyroscope are mainly used for obtaining posture data of thevehicle, including the data of vehicle acceleration, rotation angle and the like; and an inertial navigation module has the main functions of reducing a data cycle and improving the accuracy by usingan inertial navigation algorithm by utilizing the data of the sensors such as a GPS/BD module, the accelerometer and the gyroscope.

Description

technical field [0001] The invention belongs to technologies such as V2X communication technology, inertial navigation technology, improved safety distance model, and vehicle-road collaborative early warning. Data communication between connected vehicles, location acquisition, anti-collision warning prediction, and design of an online collision avoidance warning system for intelligent networked vehicles belong to the technical field of intelligent networked vehicles. Background technique [0002] At present, smart car technology is advancing at a high speed, assisted driving and automatic driving technologies have also been rapidly developed and matured, and vehicle collision avoidance and early warning functions are also becoming more and more perfect. In the field of vehicle collision avoidance warning, automatic driving is the main implementation solution. According to the automatic driving classification standard, the current automatic driving field is mainly in the sta...
