Abstract: An electronic starter and steering locking device for a motor vehicle has a steering locking unit including a locking control unit that operates an actuating unit for locking and unlocking a vehicle steering element; a vehicle starter unit for starting and shutting off the motor vehicle; and a voltage supply. The locking control unit is permanently connected to the voltage supply independently of the driving state of the vehicle, while the locking actuating unit is connected to the voltage supply via interrupter switching means which can be switched over as a function of the operating state of the vehicle starter unit and/or of the switched position of a drive train transmission shift lever.

Abstract: A system for automatic access or driving authorization for a motor vehicle includes a first device in the form of a control device having at least two states for engaging and disengaging vehicle door locks, an immobilizer, or the like. An associated second device is provided in the form of an electronic key, an ID transmitter, a chip card or the like. Both devices have means for transmitting or receiving signals, including a coded operating signal for authenticating the second device, so that a change in the state of the first device can be implemented when the second device is authorized. Before the second device is first activated, it is in a sleep state in which operation-independent function is not permitted and energy consumption is reduced. During a first operator-dependent authentication, the second device is changed over from the sleep state into a standby state in which an operation-independent function is at least partially made possible.

Abstract: An electronic closure system has one or more lockable and unlockable closure units, each arranged on an opening element of an object to be secured, at least one authorizing authentication element and a closure control unit with at least one authentication element identification sensor. The at least one authentication element identification sensor has a predetermined detection area, which covers an external detection zone outside the object. The closure control unit produces different closure control commands, related to locking and/or unlocking, based on whether and in what external detection zone authorizing authentication element is detected.

Abstract: The present invention relates to a friction brake (1, 31, 41, 51), in particular a disc brake, for a motor vehicle with a friction element (3, 33, 43, 53), e.g. a brake disc, coupled to the rotation of a vehicle wheel, forming a friction pairing of the friction brake (1, 31, 41, 51) with at least one associated brake lining (4, 5, 34, 35, 46-49), and with at least one clamping device (6, 26) for pressing at least one brake lining (5, 34, 35, 46-48) to the friction element (3, 33, 43, 53). At least one controllable friction clutch (11, 37, 54) is provided for using the rotational energy of the friction element (3, 33, 43, 53) in order to obtain the clamping force of the friction brake (1, 31, 41, 51), the friction clutch being coupled on its input end to the rotation of the friction element (3, 33, 43, 53) and on its output end to the clamping device (6, 26).

Abstract: An electronic safety system, particularly a vehicle locking system, has several safety units arranged on an object to be secured, at least one authorizing authentication element, and safety control devices with several object-side authentication element detection sensors. Signal sending devices emit a query data signal in a pertaining acquisition range, which can be received by an authentication element situated in the corresponding acquisition range. The authentication element has devices for returning an authentication response signal.
