Abstract

A system and a method for ascertaining if an ID transponder is located in the interior of a transportation vehicle. This is described as interior and exterior identification of an ID transponder. The system includes one or more of ultra-wideband transmission and receiving devices arranged on the transportation vehicle and an ID transponder having an ultra-wideband transmission and receiving device and an inertial sensor system arranged in the ID transponder by which inertial sensor system self-movements of the ID transponder are recorded, wherein each of the access openings is associated with at least one of the one or more of ultra-wideband transmission and receiving devices arranged on the transportation vehicle. A transportation vehicle and an ID transponder with which the method is performed.

First claim

The invention claimed is:

1. A system for a transportation vehicle, the system comprising:
a plurality of access openings to an interior of the transportation vehicle, wherein each of the plurality of access openings has an open state and a closed state;
a plurality of ultra-wideband transceiver devices arranged on the transportation vehicle, wherein each of the plurality of ultra-wideband transceiver devices is associated with a different one of the plurality of access openings, wherein a communication area of each of the plurality of ultra-wideband transceiver devices completely covers an access area of the associated access opening, and wherein each of the plurality of ultra-wideband transceiver devices is configured to, in response to the associated access opening being in the open state, initiates transmitting ultra-wideband communication requests; and
an ID transponder having an additional ultra-wideband transceiver device and an inertial sensor system configured to detect and record self-movements of the ID transponder,
wherein the ID transponder, in response to receiving the ultra-wideband communication requests, transmits ultra-wideband communication responses, to the plurality of ultra-wideband transceiver devices via the additional ultra-wideband transceiver device, wherein the responses indicate the detected and recorded self-movements of the ID transponder, and
wherein the transportation vehicle determines, based on the received responses indicating the detected and recorded self-movements of the ID transponder, whether a direction of movement of the ID transponder is into the interior of the transportation vehicle or out of the interior of the transportation vehicle, and transmits an interior signal indicating, based on the determination, whether the ID transponder is identified as having entered the transportation vehicle and is located in the interior of the transportation vehicle or as having exited the transportation vehicle and is located in an exterior of the transportation vehicle.

2. The system of claim 1 , wherein the information regarding the self-movement of the ID transponder is transferred from the ID transponder to the transportation vehicle by the ultra-wideband communication.

3. The system of claim 1 , wherein the information regarding the self-movement of the ID transponder is transferred by a wireless communication which is different from the ultra-wideband communication.

4. The system of claim 1 , wherein the transportation vehicle and the ID transponder each have a vector field sensor system to determine at least from one earth-bound vector field its local direction, which direction is used as a reference direction for coordinate axes directions, with respect to which the information regarding the self-movement of the ID transponder is specified.

5. The system of claim 4 , wherein the earth-bound vector field is the earth's magnetic field and a magnetic field strength of the earth's magnetic field is determined as a vector quantity.

6. The system of claim 5 , wherein the at least one of the one or plurality of ultra-wideband transceiver devices, which is arranged on the closing component, is arranged in an area of a window or adjacent to the window of the closing component, in response to the window being opened.

7. The system of claim 1 , wherein distances from the at least one of the one or plurality of ultra-wideband transceiver devices, which are associated with the corresponding access opening, to the ID transponder are determined by the ultra-wideband communication over time, and a path segment is determined by the determined information regarding the self-movement of the ID transponder and a compatibility of the path segment with the determined distances is checked to determine a confidence value for the identification of the ID transponder entering the interior and exiting the interior, and a change takes place in the interior signal based on at least one threshold value of the confidence value.

8. The system of claim 1 , wherein the at least one of the one or plurality of ultra-wideband transceiver devices, which is associated with one of the access openings, is in each case arranged on a closing component.

9. A transportation vehicle comprising:
a plurality of access openings to an interior of the transportation vehicle, wherein each of the plurality of access openings has an open state and a closed state; and
a plurality of ultra-wideband transceiver devices arranged on the transportation vehicle,
wherein each of the plurality of ultra-wideband transceiver devices is associated with a different one of the plurality of access openings,
wherein a communication area of each of the plurality of ultra-wideband transceiver devices completely covers an access area of the associated access opening, and
wherein each of the plurality of ultra-wideband transceiver devices is configured to, in response to the associated access opening being in the open state, initiates transmitting the ultra-wideband communication requests to an ID transponder disposed in the communication area and records ultra-wideband communication responses received from the ID transponder, and
wherein the ultra-wideband communication responses received by the transportation vehicle receives from the ID transponder include data indicating self-movements of the ID transponder,
wherein the transportation vehicle determines, based on the received responses indicating the detected and recorded self-movements of the ID transponder, whether a direction of movement of the ID transponder is into the interior of the transportation vehicle or out of the interior of the transportation vehicle, and transmits an interior signal indicating whether the ID transponder is identified as having entered the transportation vehicle and is located in the interior of the transportation vehicle or as having exited the transportation vehicle and is located in an exterior of the transportation.

10. An ID transponder for a system for interior and exterior identification of the ID transponder for a transportation vehicle, wherein the ID transponder comprises an ultra-wideband transceiver device and an inertial sensor system arranged in the ID transponder, by which inertial sensor system self-movements of the ID transponder are recorded, wherein the ID transponder responds to ultra-wideband communication requests which are transmitted by one of the one or plurality of ultra-wideband transceiver devices arranged on the transportation vehicle, with ultra-wideband communication responses transportation via the further ultra-wideband transceiver device, and transfers the information regarding the self-movement of the ID transponder to the transportation vehicle.

11. The ID transponder of claim 10 , wherein the information regarding the self-movement of the ID transponder is transferred from the ID transponder to the transportation vehicle by the ultra-wideband communication.

12. The ID transponder of claim 10 , wherein the information regarding the self-movement of the ID transponder is transferred by a wireless communication which is different from a ultra-wideband communication.

13. The ID transponder of claim 10 , wherein the transportation vehicle and the ID transponder each have a vector field sensor system to determine at least from one earth-bound vector field its local direction, which direction is used as a reference direction for coordinate axes directions, with respect to which the information regarding the self-movement of the ID transponder is specified.

14. The ID transponder of claim 13 , wherein the earth-bound vector field is the earth's magnetic field and
