Automobile control system and automobile control method based on traffic light recognition

Abstract

The invention discloses an automobile control system based on traffic light recognition, which comprises a controller and a video camera connected with the controller. The controller comprises a communication module, an image processing module and an information processing module connected with the communication module and the image processing module. The invention further discloses a control method corresponding to the control system. The control method includes: acquiring images of road conditions before a vehicle, extracting characteristic information in the images; and performing corresponding judgment according to the characteristic information of the images and operating information of the vehicle. Corresponding feasible voice prompts are provided for a driver in judgment of passing through crossings, and accuracy of driving judgment of the driver can be improved greatly. Further, even the driver makes false judgment and insists on passing through the crossings, the automobile control system can automatically control the vehicle to decelerate and brake, automobile collision accidents can be avoided, and physical safety of drivers and other people can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of automobile control, and in particular relates to an automobile control system based on traffic light recognition and a control method thereof. Background technique [0002] After incomplete statistical analysis, many automobile traffic accidents are caused by running a red light or running a green light. At present, most of the traffic lights on the road have a countdown reminder function, people can clearly know how long it will take for the green light to come, and how long it will take for the red light to end; traffic lights without a countdown function will also automatically flash before the end of the traffic light. In addition to the advantages of humanization, these functions are actually accompanied by some safety hazards. These reminders often become reminders for drivers to step on the accelerator and drive through the intersection before the red light arrives. [0003] When the green light o...

Problems solved by technology

In addition to the advantages of humanization, these functions are actually accompanied by some safety hazards. These reminders are often used as reminders for drivers to step on the accelerator and drive through the intersection before the red light arrives.

[0003] When the green light on the horizontal section is about to end, it also means that the green light on the vertical section is about to turn on. At this time, the vehicles on the horizontal section must drive through the intersection before the end of the green light. Good judgment and estimation, once the judgment and estimation is wrong, the driver drives the vehicle and tries to quickly cross the intersection, it is easy to collide with the cars and pedestrians who are just about to cross the intersection in the longitudinal section. Collision accidents, the severity of the accident is very large; and the existing vehicles do not have the corresponding safety measures and implementation systems to eliminate and avoid such situations
