Description

Technical Field

[0001] The present invention relates to the field of vehicle auxiliary systems, and particularly to a method, system and storage medium for controlling vehicle prompt sounds. Background Art

[0002] With the development of science and technology, cars have become the preferred means of transportation for the public. However, accidents such as "peeking and killing" often occur; "peeking and killing" refers to the scenario where the line of sight on the front side of a vehicle is blocked by other vehicles or obstacles during driving, and pedestrians or vehicles suddenly appear from the visual blind spots such as the front and rear of the vehicle or buildings on both sides of the road. If the driver fails to avoid in time, it often causes tragic accidents of vehicle injuring people and causing deaths. As one of the most difficult-to-avoid traffic accidents, "peeking and killing" has always been a pain point during driving.

[0003] Currently, a relatively effective measure for "peeking and killing" is to use the vehicle networking V2X technology. The rear vehicle shares the perception results of the sensors of the vehicle in front or the infrastructure, so as to obtain the situation of traffic participants in the blind area, predict the collision risk accordingly, and avoid traffic accidents. However, the cost of the vehicle networking V2X technology is high, and it is necessary to build basic supporting facilities related to the V2X platform; moreover, the coverage range is small, and it can only be used on sections where the infrastructure related to the V2X platform is built; and currently, the V2X technology is still in its infancy, lacking a unified industry standard, and it is temporarily impossible to achieve large-scale popularization.

[0017] S213: Record the current map coordinate position Z2 of the vehicle, and turn on the horn reminder switch after continuing to drive for a preset time period or a preset distance.
