The present invention relates to a calibration method for a wheel speed sensor after a collision accident of an autonomous vehicle, capable of determining calibration or substitution of a wheel speed sensor after malfunctioning of the wheel speed sensor is checked. The calibration method for a wheel speed sensor after a collision accident of an autonomous vehicle includes: a step of obtaining lane information on a road while the wheel speed sensor is in a normal state after a vehicle collides with a peripheral vehicle; a step of estimating the malfunctioning of the wheel speed sensor by identifying a collision position of the vehicle when the vehicle collides with the peripheral vehicle; a step of calculating first vehicle speed information by using the lane information when it is estimated that the wheel speed sensor malfunctions; a step of comparing wheel speed information measured by the wheel speed sensor and the first vehicle speed information; and a step of determining that the wheel speed sensor malfunctions when a comparison result is outside a predetermined error range by comparing the first vehicle speed information and the wheel speed information and using the first vehicle speed information by calculating the first vehicle speed information instead of the wheel speed sensor according to a malfunction degree of the wheel speed sensor or using second vehicle speed information measured by calibrating the wheel speed sensor.

    본 발명은 자율주행차의 충돌 사고 후 휠속도 센서의 보정 방법에 관한 것으로, 본차량과 주변차량 간 충돌 전에 휠속도 센서가 정상인 상태에서 도로의 차선정보를 획득하는 단계; 상기 주변차량과 충돌 시 본차량의 충돌 위치를 파악하여 상기 휠속도 센서의 고장 여부를 추정하는 단계; 상기 휠속도 센서가 고장인 것으로 추정되면 상기 차선정보를 이용하여 제1 차속정보를 계산하는 단계; 상기 제1 차속정보와 상기 휠속도 센서에서 측정된 휠속정보를 비교하는 단계; 및상기 제1 차속정보와 휠속정보의 비교하여 일정 오차 범위를 벗어나면 상기 휠속도 센서가 고장난 것으로 판단하고, 상기 휠속도 센서의 고장 정도에 따라 상기 휠속도 센서 대신 상기 제1 차속정보를 계산하여 이용하거나 상기 휠속도 센서를 보정하여 측정된 제2 차속정보를 이용하는 단계;를 포함한다.
