Abstract
A side collision avoidance system and method for a vehicle combines data from radar sensors mounted on front and rear surfaces of the vehicle with data from ultrasonic sensors mounted on side surfaces of the vehicle, and detects obstacles on the basis of the combined data, so as to increase accuracy in the detection of obstacles and predict the probability of collisions with obstacles with high accuracy. The system includes: radar sensors detecting an obstacle around the vehicle; ultrasonic sensors detecting the obstacle around the vehicle; a controller combining sensor data from the radar sensors with sensor data from the ultrasonic sensors to generate combined data, detecting the obstacle on the basis of the combined data, and predicting collision or non-collision with the detected obstacle on the basis of the combined data; and a brake driver braking the vehicle when the collision is predicted.
