Abstract: A method for securing an access method for vehicles includes a mobile device and a remote control device for administration of access rights. The mobile device is repeatedly connected to the remote control device and characteristic synchronizing data are generated for each connection. One part of the synchronization data is stored in the mobile device and in the remote control device. Characteristic prior synchronization data of a preceding connection is transmitted from the mobile device to the remote control device. A consistency check is performed in the remote control device between the prior synchronization data received from the mobile device and the prior synchronization data stored in the remote control device. If the data are consistent, the connection is terminated and a synchronization interval is waited before the connection is restored for the next synchronization. If the data are inconsistent, the mobile device is blocked from further access to vehicles.

Abstract: Tire pressure control devices include first sensors to deliver repeatedly a measured value M1 for the rotation speed of the wheel. A measurand, from which the rotation speed of the associated wheel can be derived, is detected in a pointwise manner by means of a second sensor over a predetermined rotation angle ? of the wheel as a function of time, is subjected to a low pass filtering in a subsequent first time interval ?t1 and from the filtered development of the measurand a second measured value M2 is determined, which is a measurement for the rotation speed or respectively for the angular speed of the associated wheel. Each tire pressure control device transmits at the end of a second time interval ?t2 the second measured value M2 together with an identification of the tire pressure control device to a central unit. Comparing M1 and M2 determines wheel position.

Abstract: A door handle assembly for a motor vehicle includes an operating handle moveably supported on a handle mounting, a mechanical coupling device and a locking device. An acceleration force can move the locking device from a normal operating position, in which an actuation of the operating handle is possible, in a first blocking direction, in which an actuation of the closing assembly via the operating handle and/or the coupling device, is blocked. The locking device also blocks the door handle assembly when long lasting or strongly pronounced oscillations occur as a result of a crash. In that event, the locking device can move from the normal operating position in a second blocking direction, in which an actuation of the closing assembly via the operating handle and/or the coupling device is blocked, wherein the second blocking direction is oriented opposite the first blocking direction.
