A control drive according to the related art does not have a potentiometer that allows a position of the motor or the driven wheel to be registered. The control drive () according to the invention allows a position of the motor or the driven wheel to be registered using a potentiometer () and a defined home position to be adjusted.

Control drive with adjustable potentionmeter

An access- and starting/driving-authorization system for a motor vehicle, having a portable transponder and a control unit accomodated in the motor vehicle, in order to control the smart master-key system and the engine control unit. In inquiry/response dialogs, the transponder and the control unit enabling or blocking access to the motor vehicle, and the starting and driving of the motor vehicle, using sets of code information that are matched to each other. Starting and driving the motor vehicle after forcibly entering the motor vehicle and replacing the engine control unit, including a vehicle immobilizer and a transponder of the control units relevant for starting and driving, is prevented in that the enabling of the motor-vehicle to be started and driven, after a successful starting/driving-authorization inquiry/response dialog, is rendered dependent on a preceding, successful access-authorization inquiry/response dialog.

Access and start/drive authorization system

A vehicle security arrangement includes at least one functional control unit, which provides a first code word; a theft protection control unit, which is coupled via a bus to the at least one functional control unit; and at least one input unit, which transmits to the theft protection control unit a second code word which the theft protection control unit forwards to the at least one function control unit. The theft protection control unit may initiate the provision of the first code word and the second code word. In the at least one functional control unit, a comparison of the first code word of the at least one functional control unit with the second code word takes place. In case of agreement between the first code word and the second code word, the at least one functional control unit enables itself.

Vehicle security device

A device or arrangement for exchanging data between a main station (master) ( ) and at least one secondary station (slave) ( ), which each have access to at least one common data line ( ) via interfaces CAN, and processes for operating the device. Except for an individual identifier (a, b, . . . , d) of each slave ( ), which is stored in an identifier memory ( ) disposed in the slave ( ), the slaves ( ) are identical. The master ( ) likewise includes an identifier memory ( ), in which the identifiers (a, b, . . . , d) of the slaves ( ) are to be stored, so that the master can address the slaves ( ) in a targeted way and can process the data output by the slaves ( ). The processes according to the invention pertain to the storage of the identifiers (a, b, . . . , d) in the identifier memory ( ) of the master ( ) and to the procedure in the event of ai failure of slaves ( ) and/or of the master ( ), taking into account the case where no external computer ( ) that could furnish all the required information is available. The device according to the invention and the processes according to the invention are especially suitable for use in a multiplexing system that is preferably disposed in a motor vehicle.

Device for exchanging data and process for operating it

Drive-away blocking device

A vehicle security system with an anti-theft controller which conducts a data exchange with at least one function controller, particularly an engine controller, in order to control its operational readiness, wherein the data exchange is conducted via a data line connecting at least the anti-theft controller and the function controller. Alternatively, an external device (4) can be connected to the data line (1), with the device being configured for the exchange of data with at least one of the controllers (2, 3, 3', 3') The data line is a line which is already in existence in the vehicle, particularly a K-diagnostics line and/or an L-diagnostics line in accordance with ISO standard 9141. For the control of the data exchange, one of the controllers (2, 3) connected via the data line (1) exercises the functions of the control unit. If an external device (4) is connected to the data line (1, 1'), the external device assumes the function of the control unit from the controller (2, 3) controlling the data exchange in order to conduct the data exchange with the controllers (2, 3, 3', 3') connected via the data line (1).
