Abstract

The invention relates to a method for detecting a functionality of an environment sensor of a vehicle (100), comprising the following steps: determining (200) current coordinates (X, Y) of the vehicle (100); determining (240) a current orientation (phi) of the vehicle (100); determining (250) at least one object (310) in the environment (190) of the vehicle (100) and a target position (Z1, Z2) of the object (310) in relation to the vehicle (100) according to the determined coordinates (X, Y), the determined orientation (phi), a predetermined position of the environment sensor on the vehicle (100) and a map (300) of the environment (190), wherein the map (300) comprises at least the object (310) and a position of the object (310); detecting (260) the environment (190) of the vehicle (100) by means of the environment sensor; generating (270) environment data according to the detected environment (190); detecting (280) an actual position (W1, W2) of the determined object (310) in the environment (190) of the vehicle (100) according to the environment data; and detecting (290) a functionality of the environment sensor by comparing the actual position (W1, W2) of the object (310) with the target position (Z1, Z2) of the object (310); and / or calibrating (291) the environment sensor according to the actual position (W1, W2) and the target position (Z1, Z2).

Description

technical field [0001] The invention relates to a method for detecting the functional capability of an environmental sensor, a control unit for carrying out the method, and a vehicle having the control unit. Background technique [0002] In order to achieve sufficient reliability when driving the vehicle automatically or semi-autonomously on the basis of sensor data, the sensor or sensors used to generate the sensor data should have a predetermined accuracy. In addition, the installation position of the sensor and the orientation of the sensor should be known with sufficient precision or a corresponding calibration of the sensor should be carried out. Calibration can be complex and therefore entails high costs already in vehicle production. Contents of the invention [0003] The object of the present invention is to better recognize the function of environment sensors on the vehicle, in particular for calibrating the environment sensors. [0004] The above object is achi...
