Embodiment Construction

[0019] Examples such as figure 1 A lane departure warning control method for a vehicle, comprising the steps of:

[0020] Step 1: The lane departure warning system integrating the camera and the lane departure module is fixed on the rain sensor through the bracket;

[0021] Step 2: When the vehicle is in the driving state and the speed is greater than the set value, the vehicle lane departure warning system described in step 1 starts to work, and the state of the lane line is collected in real time through the camera;

[0022] Step: 3: Send the lane line information through the CAN signal to the lane departure module through the internal algorithm of the built-in program of the camera through the lane line state collected in step 2;

[0023] Step 4: The lane departure module judges whether the vehicle deviates from the lane through the software set in it according to the lane line information processing described in step 3; The warning signal is divided into a left lane depa...

Abstract

The invention relates to a lane departure early warning control method for a vehicle. A camera is used for acquiring the lane line state in real time; the acquired lane line state is processed through an internal algorithm of a built-in program of the camera so as to be sent to a lane departure module through a CAN signal; and the lane departure module processes and analyzes the signal and judges whether the vehicle departs from a lane or not, and if the vehicle departs from the lane, corresponding alarm signals are sent to a lane line indicator lamp and an alarm device in an instrument panel. By the adoption of the method, the problems that the vehicle is likely to depart from the lane, so that multiple safety problems are generated, and consequently the driving safety performance is not high in the vehicle driving process currently can be effectively solved; and the method is simple, the alarm manners are diverse, and the method can be widely applied to the lane departure early warning field.

Description

technical field [0001] The invention relates to a vehicle lane departure warning control method. Background technique [0002] The driving of existing vehicles all depends on the driver's manipulation. During the driving process of the vehicle, especially in the case of long-distance high-speed driving, the driver is prone to fatigue states such as negligence, drowsiness, and inattention. It is easy to slowly deviate from this lane and drive into other lanes. At this time, if there are vehicles not far in front or behind the lane that you enter by mistake, if you do not take appropriate avoidance measures, the vehicle will be in a very dangerous potential. In the collision, there are even serious consequences such as rollover and collision with guardrails, which can easily lead to traffic accidents. Obviously, relying solely on the driver to concentrate on driving is a very dangerous behavior, and it is easy to cause traffic accidents. During the development of global auto...
