  • Patent number: 8587649
    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.

  • Publication number: 20100013929
    Abstract: An event data recorder with a function of lane departure warning is revealed. The device combines a LDWS (Lane Departure Warning System) with a EDR (Event Data Recorder). The LDWS uses at least one image sensor to capture road images that are sent to a DSP for being processed and identified. The EDR uses image/audio sensors to capture images in front of the car and/or sounds of surrounding. The data is sent to a recorder and is compressed for being saved into a storage device. Thus the device not only has both functions of the EDR as well as the LDWS, it further records vehicle signals, numbers of lane departure issues, and surrounding conditions of car accidents for finding out human or vehicle faults that cause the accident. Therefore, functions and efficiency of the EDR are improved.
