A lane deviation detection device and a deviation correction judgment method

Abstract

The invention relates to a lane deviation detection device and a deviation correction judgment method. The device comprises a bearing base, a main detection mechanism, auxiliary detection mechanisms and a main control system. The bearing base is a hollow columnar mechanism with a rectangular cross section; the rear end face of the bearing base is connected with a vehicle body on the front end faceof a vehicle head; and the front end face is abutted against the rear end face of a vehicle bumper and the front end face and the vehicle bumper are distributed in parallel. The main detection mechanism and the auxiliary detection mechanisms are connected with the front end face of the bearing base and electrically connected with the main control system; and the main control system is embedded ina vehicle center console and electrically connected with a trip computer system of the vehicle. In addition, the deviation correction judgment method comprises four steps of equipment hardware assembling, software driving, deviation rectification judgment and data output. According to the method, on the one hand, the requirements of various vehicle operation can be effectively met; on the other hand, detection and early warning are comprehensive, comprehensive and timely detection and alarming can be carried out when lane deviation occurs in vehicle operation from multiple angles. Meanwhile,the deviation correction amount is accurately calculated, so that the driving safety is greatly improved.

Description

technical field [0001] The invention relates to a lane deviation detection device and method, belonging to the technical field of traffic monitoring. Background technique [0002] In driving activities, due to factors such as vehicle mechanical structure factors, natural factors, road condition factors and driver factors, vehicles often deviate from lanes without the driver's awareness, which affects the smoothness of vehicles running in each lane. It is also very easy to cause collisions between vehicles and between vehicles and roadblocks, pedestrians, and barriers due to the deviation of vehicles and cannot be corrected in time, which seriously affects driving safety. In response to this problem, although a wide variety of Lane deviation detection and alarm equipment, but in use, it is found that the current lane deviation alarm system often samples a single detection point to detect vehicle operating parameters, so the comprehensiveness and detection accuracy of data det...

[0002] In driving activities, due to factors such as vehicle mechanical structure factors, natural factors, road condition factors and driver factors, vehicles often deviate from lanes without the driver's awareness, which affects the smoothness of vehicles running in each lane. It is also very easy to cause collisions between vehicles and between vehicles and roadblocks, pedestrians, and barriers due to the deviation of vehicles and cannot be corrected in time, which seriously affects driving safety. In response to this problem, although a wide variety of Lane deviation detection and alarm equipment, but in use, it is found that the current lane deviation alarm system often samples a single detection point to detect vehicle operating parameters, so the comprehensiveness and detection accuracy of data detection are relatively poor, and it is difficult to effectively meet complex requirements. The needs of vehicle operation monitoring work under road conditions
