The method involves object dimensions of objects with which the vehicle needs to be loaded being determined automatically using an optical capture apparatus, and an arrangement of the objects in a cargo space of the vehicle being determined on the basis of the object dimensions of the objects and a cargo space dimension of the cargo space. The arrangement of the objects in the cargo space is output as a loading recommendation.

Abstract: An extension of the existing CAN FD data transmission protocol. The extension enables the use of the IPv6 protocol for the CAN bus. The CAN FD protocol is further developed in an incompatible way. One modification measure relates to the lengthening of the Data Field, which is positioned in the transmission frame after an Arbitration Field. An arbitrary number of bytes can be entered in the extended Data Field within a specified upper limit. Since the Data Field is transmitted at a higher bit rate field than the Arbitration Field, the data throughput is increased dramatically.

Abstract: A method for designating a subset of a basic set of data records stored in a memory unit and for visualizing at least a part of the designated subset on a display unit. To designate the subset on the display unit, at least two graphically delimited display regions are formed. Objects representing data records from the basic set are displayed in a first display region and the subset of objects designated or to be designated is assigned to a second display region. A subset is designated by highlighting at least one object in the first display region, moving the highlighted at least one object into the second display region and cancelling the highlighting. This allows a highly intuitive designation of a subset of datasets from a basic set. The designation method can be used particularly for generating playback lists of MP3 files.
