Abstract

A method is described for providing assistance during a parking maneuver of a vehicle, in particular of a motor vehicle, into a parking space, the parking space and a boundary object located in the area of the parking space being detected by a sensor array while the vehicle is driving by the parking space. To further simplify the parking maneuver, a boundary object type is assigned to the detected boundary object, and parking information relating to the feasibility of a parking maneuver into the parking space is generated as a function of the assigned boundary object type and as a function of the position of the boundary object in the area of the parking space. Furthermore, a device is described, in particular for implementing the above-mentioned method, for providing assistance during a parking maneuver of a vehicle, in particular of a motor vehicle, into a parking space, having a sensor array for detecting a parking space and a boundary object located in the area of the parking space while the vehicle is driving by the parking space, having an analyzer unit connected to the sensor array, and having a memory unit.
