Abstract

The invention discloses a lane departure early warning system. A camera transmits obtained vehicle front lane line boundary image information to a camera processing module, the camera processing module transmits a lane departure alarm signal to a CAN bus according to the image information, the CAN bus transmits the alarm signal to an instrument controller, an automobile instrument gives an alarm,the CAN bus transmits the alarm signal to an electric power-assisted module, and a steering wheel shakes to give the alarm. By the adoption of the lane departure early warning system, a user can set the alarm sensitivity, an operation mode is quite user-friendly, system alarm types are comprehensive and include the sound sense type, the visual sense type and the touch sense type (steering wheel vibration), the user can obtain alarm information in time and interfere in the current traveling state of an automobile in time, practicability is quite high, in addition, the automobile is safer through the system, and the system accords with the automobile safety development trend.

Description

technical field

[0001] The invention relates to the field of automotive electronics, in particular to a technology for controlling driving safety by using technologies such as image recognition. Background technique

[0002] According to incomplete statistics from the Ministry of Communications, with the substantial increase in the number of vehicles in recent years, about 50% of automobile traffic accidents are caused by automobiles deviating from the normal driving lane every year. No concentration or driving fatigue, so no matter what the weather or driving environment is, how to accurately and efficiently monitor whether the vehicle has unconscious lane departure (not caused by the driver's active operation), and timely and reasonably "comfortable" the alarm information Pass it to the driver, and then the driver takes timely response measures, which has become a key content of current car safety.

[0003] The lane departure warning system is generally composed of a came...
