US 12,008,903 B2 · Collision warning method, and system for protecting vulnerable traffic participant, and storage medium

Abstract

A collision warning method in relation to vulnerable road users (VRUs), applied in a host vehicle when being driven, obtains a relative lateral distance between a vehicle and a VRU and obtains speed of movement of the VRU in addition to speed and direction of the host vehicle. A warning scenario is determined according to the relative lateral distance and the VRU speed. A warning distance according to the warning scenario and the relative speed is calculated, a relative distance between the host vehicle and the VRU is obtained, and the issue of a corresponding level of a collision warning is determined according to a comparison between the warning distance and the relative distance.

Dependent claims

A collision warning method for protecting vulnerable traffic participant comprising:

obtaining a relative lateral distance between a host vehicle and a vulnerable traffic participant and obtaining a speed of the vulnerable traffic participant, and determining whether a warning scenario has reached according to the relative lateral distance and the speed of the vulnerable traffic participant;
obtaining a relative speed between the host vehicle relative and the vulnerable traffic participant, and calculating a warning distance according to the warning scenario and the relative speed;
obtaining a relative distance between the host vehicle and the vulnerable traffic participant, and determining whether to issue a collision warning, wherein the collision warning corresponds to a comparison result between the warning distance and the relative distance.

A collision warning system for protecting vulnerable traffic participant comprising:

a processor;
and
a non-transitory storage medium coupled to the processor and configured to store a plurality of instructions, which cause the processor to:
obtain a relative lateral distance between a host vehicle and a vulnerable traffic participant and obtain a speed of the vulnerable traffic participant, and determine whether a warning scenario has reached according to the relative lateral distance and the speed of the vulnerable traffic participant;
obtain a relative speed between the host vehicle relative and the vulnerable traffic participant, and calculate a warning distance according to the warning scenario and the relative speed;
obtain a relative distance between the host vehicle and the vulnerable traffic participant, and determine whether to issue a collision warning, wherein the collision warning corresponds to a comparison result between the warning distance and the relative distance.

3 more elements

A non-transitory storage medium having stored thereon instructions that, when executed by at least one processor, causes the least one processor to execute instructions of a collision warning method for protecting vulnerable traffic participant, the instructions comprising:

obtaining a relative lateral distance between a host vehicle and a vulnerable traffic participant and obtaining a speed of the vulnerable traffic participant, and determining whether a warning scenario has reached according to the relative lateral distance and the speed of the vulnerable traffic participant;
obtaining a relative speed between the host vehicle relative and the vulnerable traffic participant, and calculating a warning distance according to the warning scenario and the relative speed;
obtaining a relative distance between the host vehicle and the vulnerable traffic participant, and determining whether to issue a collision warning, wherein the collision warning corresponds to a comparison result between the warning distance and the relative distance.
