A method for assisting a maneuvering procedure of a motor vehicle in a parking garage is disclosed, wherein the motor vehicle moves within the parking garage during the maneuvering procedure from a drop-off site in the parking garage to a predetermined position in the parking garage, wherein the maneuvering procedure of the motor vehicle is monitored by at least one sensor of the motor vehicle, comprising the steps: establishing a communication link between a controller of the motor vehicle and a vehicle-external unit of the parking garage; transmitting climate-specific measured data that are acquired by at least one measuring point in the parking garage from the at least one measuring point to the vehicle-external unit, and calibrating the at least one sensor of the motor vehicle depending on the climate-specific measured data.

The invention relates to a method for improved data fusion during environment detection in a motor vehicle (), comprising the following steps: detecting () an environment () of the motor vehicle () using at least one sensor (); recognising () objects () in measurement data () detected by the at least one sensor (); fusioning () of the recognised objects () and the object positions thereof in an environment map (), wherein a probability of existence is/will be assigned to objects () recorded in the environment map (), and wherein the probability of existence of a recorded object () is reduced, when a free region () is measured during the detection of the position of the recorded object, wherein a respective orientation attribute () is assigned to the objects () recorded in the environment map () and recorded in the environment map (), and for a region in the sensor region () of the at least one sensor (), in which a free region () is measured, the probability of existence of an object () recorded in the region of the environment map () corresponding to the region is reduced in accordance with the assigned orientation attribute (). The invention also relates to the associated device ().

In a method for checking a first ultrasonic sensor of a motor vehicle for an occlusion, a measuring signal of the first ultrasonic sensor is acquired by an evaluation unit, and from the measuring signal, a decay time of a natural oscillation of the diaphragm of the first ultrasonic sensor, brought about by an excitation pulse, is ascertained. From the measuring signal of either the first ultrasonic sensor or a second ultrasonic sensor, an echo produced by an object located in a sensing range of the first ultrasonic sensor is ascertained, and a distance value of the object is determined on the basis of the echo. An occlusion is signaled if the decay time is less than a predetermined threshold value which would be exceeded if ice and/or dirt were to adhere directly to the diaphragm, and if the distance value is less than a predetermined maximum value.
