Lane departure warning system
First Claim
1. A system having a camera, a global positioning system (GPS) and a device with lane departure warning system (LDWS), the device being an integrated part of the LDWS installed in vehicles and comprising an internal electronic control unit (ECU) and at least a warning unit, wherein:
- the device which is an integrated part of the LDWS has a cover with a camera connection port, a GPS connection port, a power connection port, a speaker port for providing sounds from an audible warning unit and at least one LED warning light of the warning unit;
the camera is connected with the device by a wire plugged into the camera connection port to track road images in front of a car and input the road images to the electronic control unit;
the electronic control unit having a video decoder, a digital signal processor (DSP) and a memory unit for processing and recognizing images;
the global positioning system (GPS) being connected with the device by at least one wire plugged into the GPS connection port;
wherein the electronic control unit is further connected with the global positioning system (GPS) so as to obtain vehicle speed signals of the car;
while in use, the road images are captured by the camera and are input to the electronic control unit (ECU) for being processed and recognized while the electronic control unit (ECU) gets the vehicle speed signals through the connected global positioning system (GPS) so as to check and give an alarm by sending signals to initiate the warning unit so as to warn the driver once the driver departs a lane without signaling,the camera and global positioning system being the only external devices operatively connected to the device with lane departure warning system (LDWS).

Abstract
A lane departure warning system (LDWS) installed on vehicles is revealed. The LDWS includes a camera that captures road images and the data of images is sent to an electronic control unit (ECU) for processing and recognition. The ECU is directly connected with a global positioning system (GPS) that provides vehicle speed signals so as to check whether dangerous driving occurs. Once the dangerous driving occurs, a warning unit is turned on to send an alert. The conventional LDWS that complicatedly connects with vehicles parts such as turn signal lights or speedometers is replaced by connection with a GPS. Thus the convenience of installation of LDWS in vehicles is improved.
