Abstract
A headlamp control system for a vehicle includes an imaging array sensor, which has a field of view forward of the vehicle, and a control that processes images captured by the imagine array sensor. The control is operable to detect light sources in the field of view and to determine an activity level in the field of view in response to a quantity of light sources detected. The control is operable to control a headlamp of the vehicle in response to identification of at least one of a headlamp of another vehicle and a taillight of another vehicle and in response to the activity level. The control may be operable to process the captured images to detect lane markers or precipitation in the field of view and may control a steering system of the vehicle or a wiper motor of the vehicle in response to such image processing.
