Patent ID: 10048381

Abstract:
The invention relates to a scanning opto-electronic detection device and a method for sensing the surroundings of a motor vehicle 1 by scanning by means of an opto-electronic detection device 2. The detection device 2 comprises a transmission and reception optical system 4 that outputs electromagnetic rays and maps reflected rays on a detector, wherein the detector is of multiline design and comprises a plurality of detector cells for providing electrical received signals on the basis of received reflected rays, which detector cells are lined up in a detector cell stack and are evaluable in parallel measurement planes. The detection device furthermore comprises a mirror carrier 7 having mirror faces 9, 10 that are averted from one another and that are arranged in a manner tilted at a tilt angle with respect to an axis of rotation 8 of the mirror carrier 7 and map different vertical sensing regions for reflected rays onto the detector.In order to allow the surroundings of a motor vehicle to be sensed with little physical outlay by means of an opto-electronic detection device having as large a sensing region as possible, the invention provides for determined tilt angles α of the mirror faces 9, 10 that are such that the sensing regions 14′, 14″ intersect in a central section of a total sensing region 16.
