Detailed Description
All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An intelligent lane departure early warning system comprises a front camera, a rear camera, a gyroscope sensor, an early warning display and a controller, wherein the front camera is fixed on a front windshield in a cab, the direction of the front camera faces the front, the front camera is also electrically connected with the controller of the lane departure early warning system, and the front camera is used for collecting position parameters of a vehicle on a current driving lane; the rear camera is fixed on an instrument desk in the cab, the direction of the rear camera faces to one side of a driver, the rear camera is also electrically connected with a controller of the lane departure early warning system, the rear camera collects driving state information of the driver, the driving state information comprises fatigue information and rotating steering wheel information, the gyroscope sensor is arranged in the controller, and the gyroscope sensor is used for collecting steering angle information of the vehicle; the early warning display is fixed on an instrument desk on one side of the cab close to the driver and is electrically connected with the controller of the lane departure early warning system, and the early warning display is used for sending lane departure early warning information to the driver; the controller is installed and fixed at the inner side of a front instrument board in a cab, is electrically connected with an automobile ignition switch and is used for comprehensively calculating and processing the information collected by the front camera and the rear camera, the steering angle information of the vehicle and the state information of a driver.
According to the working principle, when a driver is in a fatigue driving state or does not actively rotate a steering wheel to perform doubling operation, and the steering angle of the vehicle does not exceed a set value, the time that the vehicle will cross a lane marking line is identified through a front camera, and when the time is lower than the set value, a system triggers an early warning display to send out lane departure sound early warning to the driver so as to remind the driver to correct the driving direction in time and improve the driving safety.
Firstly, implementation of lane departure early warning can be realized: recognizing fatigue driving of a driver through the rear camera, and recognizing that the vehicle deviates from the current traffic lane or is about to cross the lane to run through the front camera at the moment; recognizing that the driver does not actively operate a steering wheel to turn or merge the vehicles through the rear camera, and recognizing that the vehicle deviates from the current lane or is about to cross the lane to run through the front camera; recognizing that the steering angle of the vehicle does not exceed a set value through a gyroscope sensor, and recognizing that the vehicle deviates from the current lane or is about to cross the lane to run through a front camera;
secondly, shielding of lane departure early warning can be realized: the rear camera recognizes that the driver consciously rotates the steering wheel to carry out turning and line combining operations on the vehicle; the fact that the steering angle of the vehicle exceeds a set value is recognized through the gyroscope sensor (the fact that the driver actively operates the vehicle to carry out turning or merging operation at a certain angle can be recognized without a rear camera).
The above-mentioned shield adjustment notice:
1. even if the vehicle is deviated from the current lane or is about to deviate from the current lane to drive, the intelligent lane departure early warning system cannot send out lane departure early warning reminding so as to avoid influencing conscious normal operation of a driver, avoid frequent alarm to interfere normal operation of the driver and improve driving safety;
2. in order to avoid frequent alarming, some lane departure early warning systems shield lane departure early warning especially when the vehicle is running at low speed, such as 40 km/h, while an intelligent lane departure early warning system can shield lane departure early warning according to the driving state of a driver and the active operation behavior of the vehicle, such as fatigue driving of the driver, or the driver does not actively rotate a steering wheel to carry out turning or merging operation, or the steering angle of the vehicle does not exceed a set value (which is equivalent to that the driver does not carry out emergency turning or merging operation at a certain angle) and can timely send a lane departure early warning prompt to the driver; when the driver actively rotates the steering wheel or the steering angle of the vehicle exceeds a set value, the current turning or line pressing and lane changing driving can be recognized as an active behavior of the driver, and the early warning function of the lane departure early warning system can be automatically shielded. Through the implementation of the functions, frequent early warning can be greatly reduced, normal operation of a driver is not interfered, and the starting speed of fatigue early warning can be completely reduced and set to be 0 kilometer per hour to start.
3. The value of the vehicle steering angle setting may be changed according to the magnitude of the vehicle speed. If the current vehicle speed is lower, the steering angle value of the gyroscope is larger; the higher the vehicle speed, the smaller the steering angle value of the gyroscope. That is, when the vehicle is running at a low speed, the larger the steering angle is, the faster the deviation speed of the vehicle is, and when the steering angle exceeds a set value, it can be determined that the vehicle is turning at a large angle or is intentionally merged; when the vehicle went at a high speed, even if beat the steering wheel gently, the turn angle of gyroscope was though very little, but because the speed of a motor vehicle is higher, the vehicle also can squint current lane of traveling soon and the line ball appears and goes to adjacent lane.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
