OPTICAL MODULE FOR AN ASSISTANCE SYSTEM
First Claim
1. An optical module for a vehicle having a windshield that includes a detection region, comprisinga camera arranged at an inner side of the windshield and having a field of vision directed through the windshield toward an ambient region about the vehicle, said camera comprising a sensor having a sensor surface that includes a first section and a second section, and an objective arranged with the sensor surface for focusing a distant region on the first section to create a sharp image, andan optical assembly disposed in the field of vision and adapted for focusing the detection region on the second section to create a sharp image.

Abstract
The invention concerns an optical module for an assistance system covering an ambient region of a vehicle, having a camera arranged in the region of an inner side of a pane of glass, in particular a windscreen, of the vehicle and directed into the ambient region of the vehicle, with an objective through which a distant region can be imaged in sharp focus on a first section of a sensor surface of the camera, and having an optical assembly which is arranged in the field of vision of the camera and by which a close region covering a detection region of the pane can be imaged in sharp focus on a second section of the sensor surface of the camera. The invention further concerns a method for controlling a wiping interval of a windscreen wiper, in particular of a motor vehicle, by means of such an optical module.
