摘要 |
A steering wheel is determined to be under a counter steering state when the following two conditions are both satisfied: (I) a steering angle measured with a steering angle sensor is equal to or greater than a predetermined angle; and (II) a steering direction does not coincide with a turning direction of the vehicle. The vehicle is determined to be under a slipping state when the following two conditions are both satisfied: (I) the steering angle is equal to or greater than the predetermined angle; (II) an absolute value of a change per unit time of a difference between a left wheel speed and a right wheel speed is equal to or greater than a predetermined value. Under both the counter steering state and the slipping state, adjustment of the optical axes of the swivel lights is stopped or modified.
