Driving safety early-warning system and method for vehicle at blind zone crossing

Abstract

The invention provides a driving safety early-warning system for a vehicle at a blind zone crossing. The system comprises a roadside unit and a vehicle-mounted unit. The roadside unit is installed on a transverse bar of a roadside stand column and comprises a camera, a calculating and processing module and a wireless communication module I. The vehicle-mounted unit is installed inside the vehicle and comprises a locating module, a calculating unit, a warning module and a wireless communication module II. The invention further provides a driving safety early-warning method for the vehicle at the blind zone crossing. The calculating and processing module in the roadside unit carries out recognition and classification on the vehicle on a preset road through the camera, obtains the speed, the direction and position coordinates of the vehicle and obtains event information of the blind zone crossing through encoding, and then the event information of the blind zone crossing is broadcast through the wireless communication module I. The vehicle-mounted unit receives the event information of the blind zone crossing through the wireless communication module II and judges the driving safety status of the vehicle in combination with locating and movement status information of the vehicle-mounted unit, and the judgment result is transmitted to the warning module to remind or give an early warning to a driver in sound and graph modes.

Description

technical field [0001] The invention relates to the technical fields of intelligent traffic systems and automobile safety, in particular to a vehicle driving safety early warning system and an early warning method at intersections in blind spots. Background technique [0002] With the rapid development of the transportation industry, the number of road vehicles has increased sharply, and the road traffic safety situation has become increasingly severe. When the car is driving, the driver's sight is restricted due to the influence of terrain, buildings and trees, forming a blind spot that cannot be observed. The traffic accidents caused by this have become the focus of road traffic safety. pose a great threat. [0003] In recent years, with the advancement of dedicated short-range communication technology (DSRC), vehicle-to-vehicle information interaction is used to obtain the location and motion status information of adjacent vehicles, to judge the vehicle's driving safety ...
