Device for detecting objects on a windscreen of a motor vehicle
First Claim
1. 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, 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 imaging unit is 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.

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