Abstract: Objects are sensed by a distance sensor of a vehicle. Reflected signals are received as echo signals by the driving-environment sensor. Object distance is calculable, for example, from the propagation time of the signals. Of the sensed objects, those objects are identified which, e.g., based on their spatial disposition, are parking-space-delimiting objects. It is possible to differentiate between objects delimiting a parking space to the side (e.g., parked vehicles) and lateral parking-space delimitations (e.g., a curbstone) by evaluating the echo signals. The parking-space-delimiting objects are classified through characteristic structures of the echo signals assigned to the parking-space-delimiting objects, and an object class is assigned to each parking-space-delimiting object.
