Abstract
In the vehicle lighting control apparatus and method, it is determined that the user's steering wheel is returned from a steering angle existing in a saturated steering angle region toward a neutral steering angle region at a given speed or more. If such a steering condition is found, a swivel angle is calculated based on a swivel-angle control characteristic showing a monotonic decrease in the swivel angle when the steering angle decreases from the steering angle existing in the saturated steering angle range to a third preset angle. The third preset angle is an angle from which the swivel angle decreasing from the steering angle existing in the saturated steering range becomes zero. This calculated swivel angle is used to control the swivel angle of light irradiated from on-vehicle headlights.
