Abstract: The present invention relates to a collision avoidance system based on the detection of obstacles (e.g., other vehicles and obstructive objects) in the blind spots of a vehicle.

Abstract: The present invention relates to a collision avoidance system based on the detection of obstacles in the blind spots of a vehicle. The collision avoidance system includes turn signal lamp detection means for detecting whether a turn signal lamp of the vehicle is turned on. CCD camera means captures an image for a road environment, and outputs the captured image as road environment data, thus determining whether a current road environment indicates a winding road. Steering angle detection means detects a steering angle of the vehicle and outputs a resulting signal as a steering angle signal. Infrared sensor means transmits or receives infrared light to or from an obstacle present in the blind spot of the vehicle according to the steering angle signal, and outputs an obstacle detection signal. Warning means is configured to provide a warning of possibility of a collision between the obstacle and the vehicle to a driver.
