Beschreibung
Zusammenfassung:	A traveling control system of an autonomous vehicle includes a 2D LIDAR sensor, a wheel speed sensor for detecting a speed of the vehicle, a yaw rate sensor for detecting a rotational angular speed of the vehicle, and an error corrector for determining a straight-line situation using a LIDAR point detected by the 2D LIDAR sensor, extracting a straight lateral distance value according to the result of determination, accumulating the LIDAR point according to the trajectory of traveling of the vehicle detected by the wheel speed sensor and the yaw rate sensor, estimating an error between the accumulated point and the extracted straight line, and calculating and feeding back an offset correction parameter of the yaw rate sensor when the estimated error value is greater than a predetermined threshold value to automatically correct an error parameter of the yaw rate sensor.
