Vehicular collision warning system
First Claim
1. A vehicular collision warning system, which is used to detect barriers in at least one blind spot of a driver of a large-size vehicle, comprisingat least one image capture device installed on said large-size vehicle and used to capture images of said at least one blind spot;
- a processing unit electrically connected to said at least one image capture device to identify at least one barrier, having a preset speed, calculating a speed and a displacement of each of said at least one barrier according to positional change of each of said at least one barrier with respect with time, defining at least one attention area in images of said at least one blind spot, sending out at least one alert-triggering signal when determining that one of said at least one barrier has a displacement and a speed lower than said preset speed in one of said at least one attention area; and
at least one alert device electrically connected to said processing unit to receive said alert-triggering signal and generating an alert signal of sound, light or pictures.

Abstract
A vehicular collision warning system comprises at least one image capture device capturing images of blind spots, a processing unit receiving the images of blind spots from the image capture device, and at least one alert device. The processing unit identifies at least one barrier from the images and calculates the speed and transverse displacement of the barrier according to the positional change with respect to time. The processing unit presets at least one attention area on the image, estimates whether the barrier will appear in the attention area, sends out an alert-triggering signal to trigger the alert devices to generate sound, light, or pictures to warn the driver early. Cooperating with the speed sensor, brake system and turn light system, the vehicular collision warning system can trigger different alert signals according to the grading of danger to actively warn the driver early.
