A vehicle speed control method, device and vehicle based on traffic lights

Abstract

The invention relates to a vehicle speed control method, device and vehicle based on traffic signal lights, which are used to improve the passing efficiency of vehicles at traffic intersections. It includes: 101, detecting whether there is a traffic light in front of the vehicle; 102, if there is, screening the target signal light; 103, detecting whether the vehicle is currently in the intelligent cruise mode; 104, if it is, detecting whether the target signal light is in an ever-green state; 105, If so, check whether the target signal light is a countdown signal light; 106, if yes, check whether there is a preceding vehicle in front of the lane where the vehicle is currently driving; 107, if not, adjust the current cruising speed of the vehicle to the target cruising speed, and predict the speed of the vehicle. Longitudinal displacement; 108, determine whether the longitudinal displacement of the vehicle is greater than the first distance; 109, if greater than, control the vehicle to accelerate through the stop line in front of the lane where the vehicle is currently driving within the countdown time of the target signal light.

Description

technical field [0001] The invention relates to the field of vehicle speed control, in particular to a vehicle speed control method, device and vehicle based on traffic lights. Background technique [0002] As car ownership steadily increases, urban and inter-city road networks become more complex, and the number and types of traffic lights on the roads have increased exponentially. Changes in the number of vehicles and irregular driving by drivers have caused congestion at intersections and traffic accidents, which have seriously affected the urban traffic ecology, resulting in pollution and economic losses. [0003] In the prior art, when a vehicle arrives at a traffic intersection, the driver needs to choose to accelerate through the intersection or decelerate to stop according to experience, and the driver's irregular driving behavior can easily cause traffic accidents at the traffic intersection. SUMMARY OF THE INVENTION [0004] The purpose of the present invention ...

Changes in the number of vehicles and irregular driving by drivers cause intersection congestion and traffic accidents, which seriously affect the urban traffic ecology, causing pollution and economic losses

[0003] In the prior art, when a vehicle arrives at a traffic intersection, the driver needs to choose to accelerate through the intersection or decelerate to stop based on experience. The driver’s irregular driving behavior can easily cause traffic accidents at the traffic intersection.
