Definitions

  • the present invention relates to a control method for automatically setting up or automatically switching over a vehicle communication for data exchange between a vehicle and a remote station according to the preamble of claim 1.
  • QoS Quality of Service
  • Such a quality of service describes the quality of a communication service from the point of view of the respective user and contains various quality requirements for data transmission.
  • a suitable network connection is selected as a function of the quality of service requirements.
  • WO 98/10521 A2 discloses a mobile terminal that automatically switches between a satellite based network and a terrestrial network. The switching can take place depending on a data protocol selected by a user or automatically.
  • network slicing was also proposed, see “5G Service-Guaranteed Network Slicing White Paper” version 1.0, edition of February 28, 2017 (China Mobile Communications Corporation, Huawei Technologies Co ., Ltd., Irish Bengal AG, Volkswagen).
  • Network connections are therefore available for mobile data transmission in networks that guarantee the highest data transmission quality and transmission speeds.
  • using such network connections and reserving corresponding connection capacities is associated with comparatively high costs.
  • there is a risk of overloading such high-speed network connections with the progressive introduction of the technologies of the "Internet of Things", for example in m2m (machine-to-machine) services or in the development of autonomous driving of motor vehicles.
  • m2m machine-to-machine
  • autonomous driving of motor vehicles a large amount of data is transmitted between a vehicle and a remote station to control the vehicles, as the present invention relates, the remote station being one or more other vehicles, parts of a traffic infrastructure or manually operable terminals can act. If all this data is transmitted over the available networks with the highest data quality and data transmission rate, this is associated with high costs and a correspondingly high utilization of these networks.
  • US 2019/0258251 A1 discloses a system that improves the functionality of autonomously driving vehicles in autonomy levels 3 to 5, with extremely adaptive supercomputers being used in a platform communicating with the vehicles in order to improve the learning success of the individual vehicles.
  • Data is transmitted between the vehicle and a remote station, namely a cloud-based infrastructure that includes supercomputers.
  • Data from each Autonomy Level 3 to 5 vehicle shall be transmitted over a cellular network or other terrestrial network such as LTE where available, WCDMA, UMTS, CDMA2000, HSPA+, GSM, or a satellite network to the cloud-based infrastructure.
  • the cloud-based infrastructure analyzes this data and then transmits an update to the self-driving vehicles.
  • US 9 565 625 B1 discloses a selection of best available network connections when a vehicle is moving along a route.
  • a network coverage map is generated, which the vehicle can use to determine which network is available at which location and with which signal strength. The vehicle can thereby select one or more types of network connections in different areas along a route in order to optimize communication.
  • US 2017/0219364 A1 discloses semi-autonomous or fully autonomous vehicles, with a navigation system taking into account, in addition to the conventional parameters, the portion of a route on which the vehicle can drive autonomously. As a result, the driver can preferentially select the routes on which the vehicle drives largely autonomously.
  • WO 2020/107991 A1 discloses a method, a device and a system for autonomous vehicles.
  • the present invention is based on the object of specifying a control method for automatically setting up or automatically switching vehicle communication for data exchange between a vehicle and a remote station, with which the costs and network utilization of particularly technology-intensive and cost-intensive networks can be reduced.
  • all data is no longer transmitted using the best available network connection, but instead an available network connection is specifically selected depending on the level of autonomy with which the vehicle is currently being driven or with which the vehicle is to be driven.
  • an available network connection is specifically selected depending on the level of autonomy with which the vehicle is currently being driven or with which the vehicle is to be driven.
  • control method for automatically setting up a new vehicle communication or for automatically switching over an existing vehicle communication for data exchange between a vehicle and a remote station, the vehicle being driven in different autonomy levels, the data between the vehicle and the remote station via at least one of the following network connection types, namely a network connection in a terrestrial network, a network connection in a non-terrestrial network and parallel network connections in a terrestrial and non-terrestrial network, with the selection of the network connection type depending on a currently set and/or requested autonomy level.
  • the autonomy levels can be defined in accordance with SAE J3016, in the version applicable on the priority date of the present application.
  • a definition of five autonomy levels is provided, with no automation provided for level 0, i.e. all aspects of the dynamic driving task are carried out consistently by the human driver, even if supporting warning or intervention systems are used, and full automation in level 5 is envisaged, with a consistent execution of all aspects of the dynamic driving task by an automated driving system under all driving and environmental conditions that could be managed by a human driver.
  • level 1 the driver is supported in certain driving situations by driver assistance systems that intervene with the information about the driving environment by accelerating, decelerating or steering and with the expectation that the human driver will take over all remaining dynamic driving tasks.
  • level 2 the driver is supported in certain driving situations by one or more driver assistance systems, which intervene with the information about the driving environment, both accelerating/decelerating and steering, and with the expectation that the human driver will take care of everything remaining dynamic driving tasks.
  • stage 3 dependent automation occurs with all aspects of the dynamic driving task, except that the human driver takes control of the vehicle when requested to intervene.
  • Level 4 describes highly automated driving with all aspects of the dynamic driving task, even if the human driver does not intervene when requested and takes control of the vehicle.
  • the fastest and/or highest-quality network connection type can be selected when the autonomy level is set and/or requested at a comparatively high level, for example at level 3, 4 or 5 according to one embodiment, only at level 4 or 5 according to another embodiment, or according to another embodiment can only be selected at level 5.
  • the simultaneous use of at least one terrestrial and one non-terrestrial network is selected for this purpose by setting up the parallel network connections mentioned.
  • the best and most efficient network connection can be selected because the network connections in the terrestrial network and the network connections in the non-terrestrial network are independent of each other. This means that an adequate network connection can be made available in extremely large geographical areas.
  • connection can be established in accordance with EN-DC (E-UTRA-NR Dual Connectivity), SUL (Supplement Uplink) or SDL (Supplement Downlink) or even as carrier aggregation (CA) as described in ETSI or 3GPP Telecommunications Standards in the version in force on the priority date of the present application.

  • QoS quality of service requirements
  • the quality of service requirements can differ, for example, by the latency, the jitter, the data error rate, the packet loss rate and/or by the data throughput.
  • the quality of service requirements can differ by different Rx levels, Tx levels and/or by different RxQual values.
  • the network connection type is selected as a function of the signal propagation time currently reached and/or a predetermined signal propagation time.
  • Network connections with different signal propagation times and/or different data throughput rates can be selected within the terrestrial network and/or within the non-terrestrial network, and one of these network connections within the corresponding network is selected depending on the set and/or requested autonomy level and/or in Dependence on the software applications and/or hardware applications activated and/or requested in the vehicle. This enables even better optimization of the network connection selection and extremely efficient use of the available networks to be achieved.
  • the data transmission in the non-terrestrial network takes place in particular via satellites.
  • the data transmission in the terrestrial network takes place, for example, via one or more mobile radio networks, in particular with different mobile radio standards.

  • a mobile radio standard with a comparatively higher data transmission rate can be selected if different high data transmission rates are available to be selected in different mobile radio standards.
  • WLAN-based network connections can preferably also be selected in addition or as an alternative to mobile radio networks.
