Publication number: 20150248801Abstract: An access arrangement for a vehicle includes a vehicle-side transceiver for transmitting query signals in a chronologically successive manner in first specified time intervals. The access arrangement also includes at least one mobile identification transmitter including an identification transmitter-side transceiver with an adjustable reception sensitivity for receiving the query signals of the vehicle-side transceiver. Furthermore, the access arrangement includes a monitoring device for outputting a control command in order to reduce the sensitivity of the identification transmitter-side transceiver by a first specified amount if the identification transmitter-side transceiver has received a specified number of query signals transmitted by the vehicle-side transceiver. By reducing the reception sensitivity, a stationary identification transmitter in the vicinity of the vehicle for example remains operational but no longer reacts to query signals of the vehicle-side transceiver, whereby power can be saved.Type: ApplicationFiled: September 3, 2013Publication date: September 3, 2015Applicant: Continental Automotive GmbHInventors: Herbert Froitzheim, Alexander Kramer

Publication number: 20100215076Abstract: In a method and a device (10) for transmitting a digital signal sequence, with a prescribed number of individual signals, over large distances relative to the transmission power, the digital signal sequence is repeatedly sent from a first communication device (1, 1a).

The sequence of individual signals is converted into a sequence of symbol values representing the individual signals and stored in a register (24).

Patent number: 7482921Abstract: The device and the method enable the localization of transponders, particularly in motor vehicles. A determination of the distance of different transponders from the base station is made possible by evaluating the different request signals and response signals received and also the physical variables contained therein, such as signal level, charging time, and signal propagation delay. As a result of the relative determination of the different distances of the transponders from a base station, it is for example possible to determine the position of wheels of a motor vehicle. This means savings in terms of tire electronics, which require a separate power supply and are technically more complicated and more expensive to use than transponders.Type: GrantFiled: July 19, 2005Date of Patent: January 27, 2009Assignee: Siemens AktiengesellschaftInventors: Herbert Froitzheim, Matthias Münch, Dieter Wanger

Patent number: 7271711Abstract: A device and a method for determining a wheel position on a vehicle, for example an automobile. Long-wave antennae of a vehicle access system already present in the vehicle transmit a signal, which is measured by a long-wave receive unit of a tire electronic system and used to detect the position of the wheel on the vehicle.
