Abstract

A motor vehicle, which includes a redundantly designed communications system which has a first communications device for the communication via a first wireless communications network, a second communications device for the communication via a second wireless communications network, and a control unit for the redundant operation of the first communications device and the second communications device. A parking lot for motor vehicles and a communication system are also described.

Claims

1. A motor vehicle, comprising:

a redundantly developed communication system situated in the motor vehicle, the communication system including a first communication device for the communication via a first wireless communication network, a second communication device for the communication via a second wireless communication network, and a control unit for redundant operation of the first communication device and the second communication device so that two communication channels are created, a first one of the two communication channels being via the first communication device, and the other of the two communication channels being via the second communication device, the motor vehicle communicating, via the first communication device, with a communication system of a parking lot via the first one of the two communication channels, and the motor vehicle switching, via the control unit, to communicating, via the second communication device, with the communication system of the parking lot via the other one of the two communication channels only when the first one of the two communication channels malfunctions or experiences interference;

wherein data, communicated between the motor vehicle and the communication system of the parking lot using the first communication channel of the two communication channels via the first communication device and using the other one of the communication channels via the second communication device, include data for carrying out, by the motor vehicle, an automatic parking operation.

2. The motor vehicle as recited in claim 1, wherein the first communication device and the second communication device are developed as communication devices that are separate from each other.

3. The motor vehicle as recited in claim 2, wherein one of the two communication devices is encompassed by a main unit of an infotainment system.

4. The motor vehicle as recited in claim 2, wherein one of the two communication devices is encompassed by a vehicle module for carrying out the automatic parking operation.

5. The motor vehicle as recited in claim 1, wherein the first communication device and the second communication device are encompassed by a shared communications device.

6. The motor vehicle as recited in claim 1, wherein the first wireless communication network is a first one of a WLAN communication network, a mobile telephony communication network, or a LoRa communication network, and the second wireless communication network is a second one of the WLAN communication network, the mobile telephony communication network, or the LoRa communication network, the first one being different than the second one.

7. The motor vehicle as recited in claim 1, wherein the data for carrying out the automatic parking operation include driving-command data of one or more driving commands that the motor vehicle is to execute.

8. The motor vehicle as recited in claim 1, wherein the data for carrying out the automatic parking operation include setpoint-trajectory data for a setpoint trajectory along which the motor vehicle is to travel inside the parking lot.

9. The motor vehicle as recited in claim 1, wherein the data for carrying out the automatic parking operation include map data of a digital map.

10. A parking lot for motor vehicles, comprising:

a redundantly developed communication system situated in the parking lot, the communication system including a first communication device for the communication via a first wireless communication network, a second communication device for the communication via a second wireless communication network, and a control unit for redundant operation of the first communication device and the second communication device so that two communication channels are created, a first one of the two communication channels being via the first communication device, and the other of the two communication channels being via the second communication device, a server of the parking lot communicating, via the first communication device, with a communication system of a motor vehicle via the first one of the two communication channels, and the server switching, via the control unit, to communicating, via the second communication device, with the communication system of the motor vehicle via the other one of the two communication channels only when the first one of the two communication channels malfunctions or experiences interference;

wherein data, communicated between the motor vehicle and the server of the parking lot using the first one of the communication channels of the two communication channels via the first communication device and using the other one of the communication channels via the second communication device, include data for carrying out, by the motor vehicle, an automatic parking operation, the server configured to control or coordinate the automatic parking operation in the parking lot.

11. The parking lot as recited in claim 10, wherein the first communication device and the second communication device include a plurality of transceiver units, which are spatially distributed within the parking lot.

12. The parking lot as recited in claim 10, wherein a respective transceiver unit of the first communication device and a respective transceiver unit of the second communication device are at least partially developed as communication devices that are separate from each other.

13. The parking lot as recited in claim 10, wherein a respective transceiver unit of the first communication device and a respective transceiver unit of the second communication device are at least partially developed as a shared communication device.

14. The parking lot as recited in claim 10, wherein the first wireless communication network is a first one of a WLAN communication network, a mobile telephony communication network, or a LoRa communication network, and the second wireless communication network is a second one of the WLAN communication network, the mobile telephony communication network, or the LoRa communication network, the first one being different than the second one.

15. The parking lot as recited in claim 10, wherein the data for carrying out the automatic parking operation include driving-command data of one or more driving commands that the motor vehicle is to execute.

16. The parking lot as recited in claim 10, wherein the data for carrying out the automatic parking operation include setpoint-trajectory data for a setpoint trajectory along which the motor vehicle is to travel inside the parking lot.

17. The parking lot as recited in claim 10, wherein the data for carrying out the automatic parking operation include map data of a digital map.
