Door area monitoring device for monitoring the swing area of an automobile vehicle door
First Claim
1. A door space monitoring device for monitoring a door swing area of a vehicle door, with sensor means sensing in the door swing area, with a sensor-data evaluating evaluation unit and with a control unit for controlling the sensor means or evaluation unit, where the monitoring area sensed by the sensor means is substantially two-dimensional, that the sensor means includes at least one light source for emission of a pivotable light beam, at least one micro-mirror-unit and at least one photo-detector for monitoring the two-dimensional monitoring area.

Abstract
The invention concerns a door space monitoring device for monitoring a door swing area of a vehicle door.
The door space monitoring device is provided with a door swing space monitoring sensor means, with a sensor-data evaluating evaluation device, and with a control unit for controlling the sensor means or evaluation device. The sensor means includes a light source for emission of a pivotable light beam, a micro-mirror-unit and a photo-detector for sensing the two dimensional monitored area. Preferably the micro-mirror-unit is provided with at least one micro-mechanical pivotable planar mirror and an additional non-planar mirror. The door space monitoring device is characterized by a very compact and reliable functionality.
