Abstract:
A radio key for an access system of a motor vehicle includes a receiver circuit with at least three LF receiver coils for reception of a low frequency signal. The receiver coils are oriented in different spatial directions. A central control circuit includes a microcontroller coupled to the receiver circuit. The control circuit with the microcontroller can assume an energy-reduced resting state and an active operating state. The receiver circuit is configured to awaken the control circuit from the resting state when a signal is received by the LF receiver coils. The central control circuit is configured to activate each of the LF receiver coils separately and to query a received signal strength. The central control circuit then selects the LF receiver coil with the highest signal strength for a subsequent signal reception.

Claim (Index 3):
A method for operating a radio key for a motor vehicle access system, which has an assembly composed of at least three LF receiver coils for a low frequency signal reception, wherein the LF receiver coils are oriented in different spatial directions, containing the following steps:\n detection of received signals at the LF receiver coils using a receiver circuit; if a signal is received at one of the LF receiver coils, waking up of a central control circuit coupled to the receiver circuit based on the received LF signal, wherein a microcontroller in the control circuit is brought from an energy-reduced resting state to an active operating state when the control circuit is woken up; activation of each of the LF receiver coils by the microcontroller, and querying the received signal strengths; selection of the LF receiver coil with the highest signal strength for a subsequent signal reception.
