Lane departure warning device used when connecting with global positioning system

Abstract

The invention relates to a lane departure warning device used when connecting with a global positioning system, a photographic lens is adopted to read a road image which is then transmitted to an electronic control unit that deals with image identification, and a vehicle speed signal provided by the global positioning system is directly connected and adopted in combination to judge whether the driving is dangerous or not, if yes, the signal is transmitted to a warning unit, such as a vision warning unit and / or an audition warning unit and / or a vibration warning unit, so as to send out vision and / or audition and / or vibration warning to achieve the lane departure warning effect, wherein by connecting with and utilizing the vehicle speed signal provided by the global positioning system to replace for connecting with and utilizing a vehicle body signal in the prior art, thus the installation programs of setting the lane departure warning device on the vehicle are greatly reduced, thereby promoting the convenience and using efficiency of installing the lane departure warning device, promoting the acceptance of consumers and being beneficial to popularization of the lane departure warning device.

Description

technical field [0001] The invention relates to a lane departure warning device, especially a lane departure warning device which is connected with a global positioning system (GPS) and can directly use the vehicle speed signal provided by the global positioning system to achieve the lane departure warning function. Background technique [0002] Automobiles are a popular means of transportation. In recent years, according to the needs of users (drivers), various electronic equipments are often installed, such as global positioning system (global positioning system, GPS), lane departure warning system (Lane Departure Warning System, LDWS), driving recorder (Event DataRecorder, EDR) etc., wherein, global positioning system (GPS) is to utilize a GPS receiver such as the global positioning system with C / A code WGS-84 ellipsoidal coordinate system to receive the satellite of GPS The vehicle positioning data in the signal can cooperate with the preset electronic map (e-map) and di...

AI Technical Summary

Problems solved by technology

[0004] However, so far, the electronic control unit (ECU) of the existing lane departure warning system (LDWS) is connected to the steering wheel or the left and right direction lights or the speedometer by wires to obtain vehicle body signals such as left and right direction lights or vehicle speed. etc., to be combined with the image of the lane line for identification and judgment, so that the existing circuits and equipment of the car will be used when installing the Lane Departure Warning System (LDWS), which is relatively easy to cause changes in the interior equipment and appearance of the car; and because There are many types of vehicles in each factory, and the equipment of each type of vehicle may also be different, so it is relatively more difficult to connect the car body signal; especially consumers generally do not like to change or affect the interior of the original car in order to install electronic equipment Equipment and appearance, so the willingness to install the lane departure warning device is relatively reduced, which is not conducive to the popularization and use efficiency of the lane departure warning device; moreover, the interior space of the car is limited, and the global positioning system (GPS) has been used by most cars. Adopted, but it is separate from the Lane Departure Warning System (LDWS) and must be installed separately, which not only easily causes inconvenience in installation, but also cannot be used in combination, and relatively increases the manufacturing cost and installation cost, becoming an additional installation in the car The regret of such electronic equipment also relatively affects the use efficiency of such electronic equipment
