Embodiment 1

[0119] The signal light device can first determine the number of vehicles that can pass in the north-south direction according to the traffic conditions, and use its own communication module to notify the first vehicle in the north-south direction of the number of vehicles that can pass this time through wireless transmission, assuming 3 vehicles.

[0120] After the first vehicle in the queue receives the number of vehicles that can pass, it can inform the second vehicle of the number of vehicles that can pass, and at the same time inform the second vehicle of its position in the queue, that is, 2nd place;

[0121] After the second vehicle receives the number of vehicles that can pass and its own rank in the queue, it can determine that it can pass through the intersection in this pass cycle (rank 2<number of vehicles that can pass 3), and The third vehicle may be informed of the number of vehicles that can pass, and at the same time, the rank of the third vehicle in the queue...

Embodiment 2

[0137] The signal light device can first determine the distance of vehicles that can pass in the north-south direction according to the traffic conditions, and use its own communication module to notify the distance that the first vehicle in the north-south direction can pass this time through wireless transmission. Vehicles within 200 meters of the device can pass through the intersection during this pass cycle.

[0138] The first vehicle receives the passable vehicle distance D 1 After that, it is judged whether the car can pass through the intersection, assuming that the length of the first car is L 车1 is 4.5 meters, then you can determine that you can pass the intersection (4.52 and sent to the second vehicle, the calculation process can specifically be:

[0139] D. 2 =D 1 -L 车1 -c, assuming that the vehicle distance c is 0.8 meters, then the passable distance sent to the second vehicle is D 2 =200-4.5-0.8=194.7 meters;

[0140] The second vehicle receives the passab...

Abstract

The invention provides a vehicle control method and device. The method comprises the steps of: determining vehicles on a lane on which passing is going to be allowed; sending a preset first passable vehicle parameter to the vehicles; determining the first passable vehicle parameter when the vehicles are waiting for passing; according to the first passable vehicle parameter, judging whether the vehicle itself can pass the crossing in the passing period; and according to the judging result, determining a driving speed after passing is allowed. By adopting the scheme provided by the invention, the vehicle is enabled to judge whether the vehicle itself can pass the crossing in the passing period according to the first passable vehicle parameter, and the driving speed after passing is allowed is determined according to the judging result, so that fuel waste and traffic accidents caused by that the vehicles fail to know whether the vehicles themselves can pass the cross in the prior art are avoided; and each vehicle determines the driving speed before the passing is allowed, so that the passing efficiency is improved to a certain degree.

Description

technical field [0001] The present application relates to the technical field of vehicle intelligent driving, and in particular to a vehicle control method and device. Background technique [0002] Currently, the driving of a vehicle usually relies on a driver. During the process of manually driving a vehicle through an intersection, due to reasons such as human reaction speed, driving skills, and vehicle performance, after the intersection signal light turns green, the waiting vehicles start sequentially, resulting in an unnecessary enlargement of the distance between vehicles, which in turn leads to The number of vehicles passing during each green light is far from the ideal number. [0003] In addition, each vehicle is not sure whether it can pass the intersection during this period when the signal light changes, which may cause unnecessary waste of fuel, for example: accelerating sprint but suddenly changing to a red light and being basketed; Consider that for an inter...
