Abstract: A vehicle includes first and second steering drivers that steer first and second wheel pairs, a lock that locks the first wheel pair to be non-steerable, a first steering controller that controls the first steering driver in accordance with a first steering angle, and a second steering controller that controls the second steering driver in accordance with a second steering angle. The first steering controller controls the lock to lock the steering of the first wheel pair upon detecting anomaly in the steering of the first wheel pair from the steering angle and a steering detection angle of the first wheel pair. The second steering controller controls the second steering driver in accordance with a second corrected steering angle, if the steering of the first wheel pair exhibits anomaly.

Abstract: A vehicle includes first and second steering drivers that steer first and second wheel pairs, a steering for the first and second wheel pairs, a detector that detects a steering detection angle of the first wheel pair, a lock that locks the first wheel pair to be non-steerable, a first steering controller that controls the first steering driver in accordance with a first steering angle, and a second steering controller that controls the second steering driver in accordance with a second steering angle. The first steering controller controls the lock to lock the steering of the first wheel pair upon detecting anomaly in the steering of the first wheel pair from the steering angle and the steering detection angle. The second steering controller controls the second steering driver in accordance with a second corrected steering angle, if the steering of the first wheel pair exhibits anomaly.
