System and method for automatic control of automobile turn signal

Abstract

The invention relates to an automatic control system and method for automobile steering lamps. The system comprises a front-view camera, a video processing module, a control processor and a power supply module, wherein the video processing module is separately connected with the front-view camera and the control processor and is connected with a vehicle-mounted sensor; the controller processor is connected with the automobile steering lamps; the power supply module is separately connected with the front-view camera, the video processing module and the control processor. The front-view camera is used for collecting images in front of an automobile; the video processing module is used for judging whether a driver in the automobile changes lanes or not according to video signals of the collected images and signals of the vehicle-mounted sensor, and transmitting lane changing signals to the control processor; the control processor is used for controlling the switching on and the switching off of the steering lamps; the power supply module is used for supplying electricity to other modules. According to the method, the images of conditions in front of the automobile are collected, and the switching on and the switching off of the steering lamps are automatically controlled by a lane recognition method and a lane changinh behavior recognition method. Compared with the prior art, the automatic control system and method disclosed by the invention have the advantages that the driving safety is improved, the control manner is simplified, and the compatible expansibility is powerful.

Description

technical field [0001] The invention relates to an automobile auxiliary device, in particular to an automobile turn signal automatic control system and method. Background technique [0002] With the popularity of automobile consumption, people have higher and higher requirements for automobile safety, and irregular driving behavior is one of the main reasons leading to accidents. Among them, not turning on the turn signal before changing lanes is the main reason for the accident of vehicles in the same direction. At the same time, the current steering wheel automatic return system uses sensors to detect the steering wheel angle, and when certain conditions are met, the turn signal is automatically turned off. However, since the system relies solely on the steering wheel's steering information and lacks direct vehicle position information within the lane, in some cases (such as entering a large curve, or when the vehicle crosses the line, the steering wheel returns to a cert...

Problems solved by technology

However, since the system relies solely on the steering wheel's steering information and lacks direct vehicle position information within the lane, in some cases (such as entering a large curve, or when the vehicle crosses the line, the steering wheel returns to a certain angle) it will cause steering The lights are turned off early before the lane change process is over, causing safety hazards

[0003] As an active safety product, the forward vision system has been widely installed in various vehicles. It realizes lane departure warning, forward collision warning, lane keeping assistance, etc. through image processing. However, there is no similar system for the automatic switch of the turn signal.
