Abstract: A lidar sensor, especially for motor vehicles, having a light source, a movable deflection mirror for producing a scanning beam that sweeps across a monitored space by deflecting a light beam emitted by the light source, and having an optical receiver for detecting light reflected by an object hit by the scanning beam in the monitored space. The light source and the deflection mirror are adapted for using the deflected light beam to scan an array of micro-optical elements, each of which, in response to being impinged upon by this light beam, widens it into a divergent beam; and, configured at a distance from the array of micro-optical elements, is a light-concentrating element that transforms the divergent beam into a beam which forms the scanning beam and whose beam diameter is larger than that of the deflected beam.

Abstract: A sensor system for a vehicle for detecting bridges and tunnels is described, which includes a lateral LIDAR sensor, which is located on a first side of the vehicle and has a detection area covering a lateral surrounding area of the vehicle, and a control unit for evaluating the measuring data from the lateral LIDAR sensor. The lateral LIDAR sensor is positioned rotated about a vertical axis so that part of the detection area of the lateral LIDAR sensor at the front in the travel direction detects an upper spatial area located at a predefined distance ahead of the vehicle. The lateral LIDAR sensor is tilted about its transverse axis with respect to the horizontal, so the detection area of the lateral LIDAR sensor detects the remote upper spatial area at a predefined height above the vehicle using its part which is at the front in the direction of travel.

Abstract: A sensor system for a vehicle for recognizing adjacent vehicles, situated in an adjacent lane, with protruding or exposed objects, is described which includes a first lateral LIDAR sensor. The first lateral LIDAR sensor is tilted about a first transverse axis with respect to the horizontal, so that the first detection range, with its front portion in the travel direction, detects a first upper spatial area laterally ahead of the vehicle, at a height above the installed position of the first lateral LIDAR sensor. The second lateral LIDAR sensor is tilted opposite to the tilt direction of the first LIDAR sensor about a second transverse axis with respect to the horizontal, so that the second detection range, with its rear portion in the travel direction, detects a second upper spatial area laterally behind the vehicle, at a height above the installed position of the second LIDAR sensor.
