摘要： 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. According to the invention, the query data signals emitted by the detection sensors contain a sensor-specifically coded data protocol range, and the authentication element has devices for analyzing the sensor-specifically coded data protocol range of received query data signals and for generating an authentication response signal which contains a sensor-indicative data protocol range which is coded with the information as to from which detection sensors the authentication element has received a query data signal.

摘要： A method for storing odometer reading data in a vehicle having control units which are connected via a data bus. The odometer reading data, which is determined at a particular time by an odometer, is stored in a storage means of a first control unit. This provides an alternative method for tamper-proof storage of odometer reading data and, in particular, improved protection against errors during the transmission of the odometer reading data. The current odometer reading data of at least one further control unit is then stored on the data bus in a storage means. The control units transmit the odometer reading data, which is stored at a particular time, onto the data bus at specific time intervals, and a control unit accepts the odometer reading transmitted onto the data bus if that reading is higher than its stored value, and uses that value for the further counting and storage in the particular control unit.
