Abstract: A method for ascertaining a relative position between a vehicle and an object located laterally to the vehicle, and a retrofitting kit having components to carry out this method. The object is initially detected in that the vehicle passes the object at least once. Subsequently, the vehicle movement is detected by a camera system which is situated in the vehicle and which generates video images at different recording points in time. Then, the detected vehicle movement is linked to the installation position of the camera system in the vehicle, the position of the at least one object detection sensor and a reference point. Next, the relative position change of the vehicle relative to the previously detected object is determined.

Abstract: In a method for pulling a vehicle out of a parking space with assistance by a parking-assistance device, at least one pulling-out movement is performed by intervention in a steering system of the vehicle. A warning is output to a driver of the vehicle when the driver of the vehicle fails to take over the guidance of the vehicle after the assistance by the parking-assistance device in pulling out of the parking space has ended.

Abstract: A method for diagnosing an internal combustion engine in a motor vehicle having at least one sensor unit, including at least one sound receiver, the sound receiver converting sound waves into an electrical signal. Sound waves of the internal combustion engine are recorded using the sound receiver of the sensor unit and converted into an electrical signal, and the electrical signal is used for the diagnosis of the operating state of the internal combustion engine.
