1. A side collision avoidance system for a vehicle, comprising:

  • a plurality of radar sensors configured to detect an obstacle around the vehicle;

    a plurality of ultrasonic sensors configured to detect the obstacle around the vehicle;

    a controller configured to;

    combine radar sensor data from the radar sensors with ultrasonic sensor data from the ultrasonic sensors to generate combined data;

    detect the obstacle on the basis of the combined data; and

    predict collision or non-collision with the detected obstacle on the basis of the combined data; and

    a brake driver configured to brake the vehicle when the collision is predicted,wherein the controller generates covariance of the radar sensor data, covariance of the ultrasonic sensor data, and covariance of the combined data on the basis of cross-covariance of the ultrasonic sensor data and the radar sensor data.
