Abstract
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.
