Further, an autonomous traveling device includes an optical path changing device. The optical path changing device changes an angle of inclination downwardly relative to a scanning plane of the ranging device and changes a direction of an incident light from a lateral direction to a forward direction of the vehicle body. Further, the optical path changing device changes a direction of an incident light toward a foot area of the vehicle body.

摘要： An automatic parking control is cancelled when a motor current has not yet reached a maximum current value Imax with a steering angle deviation exceeding a deviation threshold value. In addition, the automatic parking control is cancelled when a steering speed has not yet reached a maximum steering speed with a state where the motor current has reached and remains at the maximum steering speed continuing over a first time period. On the other hand, when a state where the steering speed has reached and remains at the maximum steering speed continues over a second time period, it is determined that there occurs an output shortage of a steering actuator, an automatic parking condition is recalculated, so as to allow the automatic parking continue to continue.
