Anti-collision warning information external interaction method and system for passenger car

Abstract

The invention discloses an anti-collision warning information external interaction method for a passenger car. The anti-collision warning information external interaction method comprises the steps: acquiring real-time relative motion information of all obstacles around the current automatic driving passenger car; according to the real-time relative motion information of each obstacle, calculating the real-time relative collision time when each obstacle is about to collide with the passenger car, determining the danger level of the corresponding collision event according to the real-time relative collision time, and on the basis of the danger level, making a decision on the collision event of the passenger car to generate a corresponding alarm signal; and enabling the whole vehicle controller to drive the warning device to display corresponding anti-collision warning information to obstacles in all directions around the vehicle body under the control of the warning signal. From the perspective of passive safety, social vehicles and pedestrians are reminded, traffic accidents are reduced or avoided, the driving safety of automatic driving is improved; meanwhile, the intelligent level of the automatic driving vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of automatic driving, in particular to a method and system for external interaction of anti-collision warning information for intelligently driven passenger cars. Background technique [0002] With the continuous development of autonomous driving technology, autonomous driving technology has begun to seek commercial application scenarios, such as park shuttles, taxis, and buses. As self-driving vehicles begin to move towards public places, since the driving operation of self-driving vehicles depends on programs, the driving action is relatively fixed when facing various scenarios. A rear-end accident occurred. At present, the mainstream research direction is to start from the self-driving vehicle itself, focusing on the perception of obstacles and coping strategies in different scenarios to improve active safety performance, but this method only improves the self-driving technology of the self-driving vehic...

AI Technical Summary

Problems solved by technology

At present, the mainstream research direction is to start from the self-driving vehicle itself, focusing on the perception of obstacles and coping strategies in different scenarios to improve active safety performance, but this method only improves the self-driving technology of the self-driving vehicle. When an external obstacle suddenly appears in a sudden situation, the danger cannot be recognized from the perspective of the obstacle, and it can only be dealt with from its own perspective

[0003] However, in the existing technology, there are few information interaction systems that remind the society of vehicles and pedestrians from the perspective of passive safety, so as to jointly assess the current danger from the perspective of both parties involved in the collision event, including the self-driving vehicle itself and the obstacle. Response to events, reduce or avoid vehicle accidents during autonomous driving, and improve the safety of autonomous driving vehicles
