Embodiment Construction

[0053] The implementation of the embodiment of the present application will be described in detail below in conjunction with the accompanying drawings.

[0054] The method provided in the embodiment of this application can be applied to figure 1 In the driving safety warning scenario shown, such asfigure 1 As shown, the driving safety early warning scenario may include: multiple vehicles. Vehicle-to-vehicle communication can be based on long term evolution-vehicle (LTE-V) communication technology for vehicles, or dedicated short range communication (DSRC) based on 802.11p access layer protocol , without restriction.

[0055] in, figure 1 Vehicles in the network can communicate with roadside units (roadside unit, RSU) or other network devices (such as: V2X server) through wireless links. The vehicle may be an intelligent network driving (Intelligent Network Driving) vehicle, which is a typical car networking terminal. Those skilled in the art should understand that the vehi...

Abstract

The embodiment of the present application discloses an early warning method and device for the self-vehicle, which relates to the field of intelligent transportation, to solve the problem that the self-vehicle has a low safety early warning capability when the vehicles around the vehicle have accidental dangers not caused by the self-vehicle. The method includes: determining the adjacent area of ​​the vehicle according to the driving information of the vehicle; classifying the surrounding vehicles of the vehicle to obtain adjacent vehicles in multiple directions and distant vehicles in multiple directions; For any distant vehicle, calculate the minimum distance between the adjacent vehicle and the distant vehicle in each direction that matches the direction of the distant vehicle in multiple directions within a period of time in the future, and record the time T when the minimum distance is less than the threshold D; according to The recorded time T sends a warning message to the driver of the vehicle to indicate that an accidental collision accident not caused by the vehicle or other accidental collision accidents may occur in the direction of the adjacent vehicle corresponding to the minimum time T.

Description

technical field [0001] The embodiment of the present application relates to the field of intelligent transportation, and in particular to a method and device for early warning of the own vehicle. Background technique [0002] In the driving safety warning scene, vehicle collision warning has become the main application scenario of vehicle-to-vehicle (V2V) interaction, such as front vehicle collision warning, intersection collision warning, lane change warning, reverse overtaking warning, left turn auxiliary warning , blind spot warning, etc., which fully demonstrate the important value of vehicle collision warning for safe driving of vehicles. [0003] In the existing vehicle to everything (V2X) communication, the vehicle's early warning method for the collision risk of the vehicle on the road is as follows: the vehicle obtains its own motion state data, and then combines the vehicle's motion perception sensor (such as Lidar, 360 panoramic camera, millimeter-wave radar, etc...
