Abstract: The invention relates to a wireless remote control system (100) for vehicle functions (13.1, 13.2), having a portable remote control unit (20) which comprises operator control elements for activating control signals which are exchanged with a vehicle mounted transmitter/receiver unit (11) in order to control the vehicle functions (13.1, 13.2). According to the invention, the remote control unit (20) comprises the following components: at least one first operator control element which has a predefined function of an electronic driving authorization and/or access authorization system (13.2) assigned to it, and at least one second operator control element and at least one display unit for menu prompted control of at least one ride level control system (13.1).

Abstract: An arrangement for limiting the terminal voltage in an alternator has a fixed stator winding acting on rectifiers and an excitation winding which rotates with the alternator rotor. The arrangement also has a controller and a first slip ring contact which load the excitation winding with excitation current as a function of the magnitude of a delivered voltage, and at least one free-wheeling valve which is conductive during a controller-side interruption of the excitation current and is connected in parallel with the excitation winding. The arrangement includes an auxiliary winding on the rotor. The auxiliary winding continues the excitation winding in the same direction of winding, with the auxiliary winding and the excitation winding being connected at a first connection point. A second slip ring contact operatively connects the first connection point to a machine terminal supplying excitation current.
