Lane departure pre-warning device

Abstract

The invention discloses a lane departure pre-warning device provided with a camera array, an image processing module, a controller module, a sound-light alarm module and at least two accelerate detection modules, wherein one camera and one accelerate detection module form an information acquisition unit set; the camera and the accelerate detection module of each information acquisition unit set are installed at a same position of an automobile for at least detecting the distance between a left wheel of the automobile and a left lane marker, a left wheel acceleration, the distance between a right wheel of the automobile and a right lane marker and a right wheel acceleration; the acquired information is finally input into a controller module for processing. According to the arrangement of the modules and the installation mode of the information acquisition unit, the traveling condition of the automobile can be effectively detected, and an accurate data basis is provided for lane departure judgment performed by the system; and in rain and snow days or in the weather with poor visibility, the lane marker information is collected via an infrared detection module, and data detection accuracy is further improved.

Description

technical field [0001] The invention relates to safe running detection and alarm of vehicles, in particular to a lane departure warning device. Background technique [0002] According to statistics, about 50% of traffic accidents in the country are caused by vehicles deviating from the normal driving lane. When the driver is in a state of fatigue, the sensitivity to whether the vehicle deviates from the normal track is greatly reduced. Without any external intervention, it is easy to be paralyzed and even cause traffic accidents. Therefore, it is necessary to propose a driving assistance system, which can provide alarm feedback to the driver in time when the vehicle deviates from the lane, so as to attract the attention of the driver and take action in time to avoid accidents. [0003] In the prior art, various sensors are usually installed on the vehicle to collect environmental data inside and outside the vehicle for static and dynamic identification, detection and tracki...
