Patent ID: 8009023

Claim:
An access arrangement for a user to control access to a vehicle, comprising: a transmit/receive device at the vehicle to transmit one or more interrogation signals; and a mobile identification generator configured to be carried by the user and comprising: a transmit/receive device to receive interrogation signals from the transmit/receive device at the vehicle, and a control device, in response to the vehicle being turned off or a closing or opening of a door of the vehicle, to: evaluate signal characteristics of the one or more interrogation signals at at least two different points in time; automatically determine whether the mobile identification generator is physically moving based on the evaluation of the signal characteristics of the one or more interrogation signals communicated between the vehicle and the mobile identification generator; in response to determining that the mobile identification generator is not physically moving, automatically deactivate the mobile identification generator such that the mobile identification generator cannot perform a subsequent authorization operation regarding the vehicle until the mobile identification generator becomes re-activated; and in response to determining that the mobile identification generator is physically moving, automatically output a locking signal to lock at least one door of the vehicle; such that both (a) the automatic deactivation of the mobile identification generator and (b) the automatically locking of at least one door are performed based on the same signal characteristics of interrogation signals communicated between the vehicle and the mobile identification generator.
