Auxiliary driving method and system for intersection green light reminding

Abstract

The invention discloses an auxiliary driving method and system for intersection green light reminding. The method comprises the following steps: acquiring image data; analyzing the image, and determining the current lane and traffic light information; if yes, determining the color of the traffic light; if the color of the traffic light is green, judging the shape of a green light, and if the green light is round or arrow-shaped and the shape is matched with the lane information, detecting the current speed of the vehicle; if the distance is larger than or equal to the set value, detecting the current speed of the vehicle after first response time; and if the current speed of the vehicle is equal to zero, generating prompt information. The system comprises an image acquisition module, an information processing and control module, a distance acquisition module, a speed acquisition module and a prompt module. According to the method, drivers who do not know that the signal lamps at the intersection turn green can be helped to quickly adjust the driving state, so that backlog of rear vehicles can be effectively avoided, and the traffic pressure of urban roads is relieved to a certain extent.

Description

technical field [0001] The invention relates to the field of assisted driving of vehicles, in particular to an assisted driving method and system for reminding green lights at intersections. Background technique [0002] With the continuous improvement of people's living standards and the continuous development of science and technology, while the number and quality of motor vehicles continue to break through and innovate, the negative impact of traffic congestion is also particularly prominent. Among them, while waiting for the green light at the intersection, the driver of the vehicle was distracted, playing with mobile phones, reading books, etc., causing the vehicle to fail to pass the intersection or drive forward in time after the signal light changed from red to green, resulting in a serious backlog of vehicles behind and blocking traffic. At the same time, this phenomenon has become one of the main reasons for today's road traffic congestion. [0003] However, at pr...

Problems solved by technology

However, this technical solution still mainly relies on the navigation system for vehicle positioning, which requires an external GPS to complete, which not only involves copyright issues, but also makes the system more complicated and cannot be universally applied.
