Patent ID: 6841767

Claim:
A device for detecting objects on a windshield of a motor vehicle having a hood, the device comprising: a first imaging unit having a first lens and a first sensor positioned within the interior of the motor vehicle and away from the windshield, wherein the first lens images a first windshield section associated with a primary field of vision onto the first sensor, wherein the first sensor generates a first sensor signal in response to the first windshield section imaged thereon, wherein the first lens and the first sensor of the first imaging unit are positioned in a viewing direction pointing diagonally downwards with respect to the windshield such that the background of the first windshield section imaged onto the first sensor is the hood of the motor vehicle thereby causing the background of the first windshield section imaged onto the first sensor to be approximately constant in order to cancel environmental conditions that can impair object detection on the first windshield section; and an evaluation unit for evaluating the first sensor signal to detect objects on the first windshield section.
