20110148569 | METHOD FOR GAP CHARACTERIZATION IN INDUCTIVELY COUPLED ACCESS SYSTEMS - An access facility for a vehicle has a first transmit/receive device for transmitting a first radio signal and for receiving a second radio signal, a second transmit/receive device for transmitting the second radio signal and receiving the first radio signal, a transmission strength determining device for determining a transmission strength value, which represents the transmission field strength of the first radio signal transmitted by the first transmit/receive device, and a reception strength determining device for determining a second reception strength value, which represents the reception field strength of the first radio signal at the location of the second transmit/receive device. The information content of the first radio signal has the transmission strength value, and the access facility features a relation determining device for determining a relation between the transmission strength value and the reception strength value. | 06-23-2011 |
20150091513 | Charging Device for a Portable Device in a Motor Vehicle - A charging device for a portable device, e.g., in a motor vehicle, includes a resonant circuit, controllable by a trigger device, for inductive transmission of energy to the portable device, wherein the trigger device is designed such that the curve shape of the excitation for the resonant circuit is generated based on an operating state of the charging device. | 04-02-2015 |
20150248801 | Access Arrangement for a Vehicle - 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. | 09-03-2015 |
20160098870 | METHOD AND SYSTEM FOR REMOTE ACCESS CONTROL - A method to learn and then pair with a pre-installed access control system of a vehicle is discussed. Communication is exchanged between the access control system and a backend cloud-based system. Required data of the access control system including its particular authentication code is extracted by a learning device. A vehicle matching data is sent to the backend cloud-based system and the vehicle is registered with the backend cloud-based system. The learning device is registered to the access control system in accordance with learning procedures implemented in the vehicle as remote entry key. The learning device is coupled to a Radio Frequency signal transmitter that has Application-Specific Integrated Circuits to generate stable RF signals at multiple frequency wavelengths. Registration of learning device includes, receiving a first access control telegram message, transmitting the first access control telegram message to the access control system, pairing the learning device with the access control system. | 04-07-2016 |
