Abstract
The invention relates to a detection device (4) for a motor vehicle (1) for detecting a distance (x1) of an object (O1) in a surrounding region (5) of the motor vehicle (1) from the motor vehicle (1), comprising an emitting unit (8), which is designed to emit a light beam (9) and to scan the surrounding region (5) by orienting the light beam (9) along predetermined emission angles (10), and comprising a receiving unit (11) having at least two receiving elements (16), which are designed to receive a part (12) of the light beam (9) reflected on the object (O1), to detect the distance (x1) on the basis of a duration between the emission of the light beam (9) and the reception of the reflected part (12) of the light beam (9), and to detect a reception angle (13), at which the reflected part (12) of the light beam (9) from the surrounding region (5) is incident on the receiving unit (11), wherein the receiving unit (11) is designed to detect a deviation (17) between the emission angle (10) of the light beam (9) and the reception angle (13) of the reflected part (12) of the light beam (9) corresponding to the emission angle (10). The invention additionally relates to a driver assistance …
