Abstract

A system for the contactless transfer of energy and data includes a transfer path with a primary coil and with a secondary coil. The primary control unit is designed to lead data-modulated first alternating-voltage signals of a first frequency range into the primary coil. The secondary control unit is designed to receive the first alternating-voltage signals of the first frequency range from the secondary coil, and to demodulate the modulated-on data. The system further includes a feed-in line for feeding a second alternating-voltage signal of a second frequency range to a primary line leading to a primary coil and an activation line that is connected to a secondary line that is connected to the secondary coil. A first filter filters the second alternating-voltage signal from the secondary line and provides the signal to an activation connection.

Claims

1. A system for the contactless transfer of energy and data,

comprising a transfer path with at least one primary coil, connected by way of a primary line to a primary control unit, and at least one secondary coil connected by way of a secondary line to a secondary control unit,

wherein the primary control unit is configured to lead data-modulated first alternating-voltage signals of a first frequency range into the primary coil, and

wherein the secondary control unit is configured to receive the first alternating-voltage signals of the first frequency range from the secondary coil, and to demodulate the modulated-on data;

a feed-in line connected to the primary line,

an activation line connected to the secondary line, and

a first filter arranged between the secondary line and an activation connection,

wherein the first filter is permeable to second alternating-voltage signals of a second frequency range while blocking the first alternating-voltage signals of the first frequency range.

2. The system of claim 1, further comprising a switching device with a signal output, said switching device configured to controllably apply an alternating-voltage signal from the second frequency range to the signal output, wherein the signal output is connected to the feed-in line.

3. The system of claim 2, wherein the switching device is connected to a pressure sensor and is configured to lead the alternating-voltage signal of the second frequency range to the signal output if the pressure level falls below a predetermined air pressure.

4. The system of claim 1, wherein the activation connection is connected to at least one actuator configured to carry out a movement when a second alternating-voltage signal is present.

5. The system of claim 1, wherein the first filter is a low-pass filter.

6. The system of claim 1, wherein the boundaries of the first frequency range differ by a factor of 10 to 10,000 from the boundaries of the second frequency range.

7. The system of claim 1, further comprising a decoupling transmitter in the feed-in line.

8. The system of claim 1, further comprising a decoupling transmitter in the activation line.

9. The system of claim 1, further comprising a second filter in the feed-in line, said second filter corresponding to the first filter.

10. The system of claim 1, further comprising a third filter in the primary line and a fourth filter in the secondary line, wherein the third and the fourth filters let alternating-voltage signals from the first frequency range pass through while blocking them from the second frequency range.

11. The system of claim 10, wherein the third filter and the fourth filter are high pass filters.

12. A vehicle with a first vehicle part and at least one second vehicle part, which is movable relative to the first vehicle part, and a system for the contactless transfer of energy and data, the system comprising:
