Vehicle early warning method and device, control method and device and electronic equipment

Abstract

The invention discloses a vehicle early warning method and device, a control method and device and electronic equipment, and the vehicle early warning method comprises the steps: obtaining the traffic light information of an intersection, and determining a first time length; acquiring historical traffic condition information of the intersection; determining the duration of the first vehicle from the position of the current moment to the stop line of the intersection as a second duration, the duration of the target vehicle from the position of the current moment to the stop line of the intersection as a third duration, and the duration of the second vehicle from the position of the current moment to the stop line of the intersection as a fourth duration; and generating vehicle early warning information of the target vehicle according to the first duration, the second duration, the third duration, the fourth duration and the historical traffic condition information. According to the control method, motion control is performed on the vehicle according to the vehicle early warning information. The accuracy of the vehicle early warning information is improved, the congestion condition of the intersection can be improved, the driving safety can be improved, and the method can be widely applied to the technical field of intelligent traffic.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a vehicle early warning method, control method, device and electronic equipment. Background technique [0002] An intersection refers to a level intersection, that is, a position where two or more roads intersect on the same level. The intersections are generally provided with red, yellow and green traffic lights, and vehicles and pedestrians on the road pass through the intersections according to the instructions of the traffic lights. Due to the criss-crossing roads at intersections, the joint use of vehicles, pedestrians or other non-motorized vehicles, and the complex road conditions, intersections are often places where traffic accidents occur frequently and congestion occurs frequently. [0003] For example, when multiple vehicles on the same lane pass through an intersection, because each vehicle cannot accurately judge whether its own vehicle and other...

AI Technical Summary

Problems solved by technology

[0003] For example, when multiple vehicles on the same lane pass through an intersection, because each vehicle cannot accurately judge whether its own vehicle and other vehicles can pass the stop line of the intersection before the yellow light or red light comes, each vehicle Each will independently decide to accelerate through the intersection or brake to stop the vehicle according to the current situation. At this time, it is easy to cause a collision accident due to inconsistent judgments of the front and rear vehicles, and further cause traffic jams
