Abstract: An arrangement for operating one or more windows (S1-S4, SF, SH), which are installed in a vehicle (FZ) and in particular delimit a passenger compartment (FGZ) and whose optical properties can be changed by electrical actuation, comprises a position-determining device (ZGA) for determining the position (P1-P3) of an object (IDG1) which is located outside the vehicle (FZ). In addition, the arrangement has a control device (STG, AST) which is configured to actuate the one or more windows (S1-S4, SF, SH) as a function of the position, determined by the position-determining device, and in particular the distance.

Abstract: A mobile identification transmitter for an access arrangement of a vehicle, said access arrangement being supplied by a vehicle battery, comprises an identification-transmitter-side receiving device for receiving a vehicle-side request signal. Furthermore, it comprises an identification-transmitter-side transmitting device for emitting a response signal in response to the reception of the vehicle-side request signal. Finally, the mobile identification transmitter has an identification-transmitter-side control device for identifying and/or estimating the state of charge of the vehicle battery, for comparing the identified and/or estimated state of charge with a predetermined threshold value, and for identifying an emergency state of the access arrangement if the identified and/or estimated state of charge falls below the predetermined threshold value.

Abstract: An access arrangement for a vehicle comprises a vehicle-side unlocking device for unlocking a locking mechanism. Furthermore, it comprises a vehicle-side rechargeable electrical energy storage device which is set up to supply the unlocking device with energy independently of the on-board power supply of the vehicle. Moreover, the access arrangement has a vehicle-side energy supply device comprising a first section for receiving wirelessly transmitted energy and for converting the transmitted energy into electrical energy, and a second section for charging the vehicle-side rechargeable electrical energy storage device. In particular, the access arrangement also comprises a vehicle-side authentication device for checking access authorization, which is supplied with energy independently of the on-board power supply by means of the vehicle-side rechargeable electrical energy storage device.
