Abstract

The invention relates to a device for controlling the wireless communication of a motor vehicle, which takes place via a communication unit of the motor vehicle to external communication devices, with a control connection to the communication unit and with a connection to an operating unit (4) and with a computing unit. It is envisaged that the arithmetic unit of the device (1, 5) after activation via the terminal of the operating unit is set up to monitor and restrict or prevent the data communication from the motor vehicle.

Description

  • The invention relates to a device for controlling the wireless communication of a motor vehicle, which takes place via a communication unit of the motor vehicle to external communication devices. The device has a control connection to the communication unit and a connection to an operating unit. Furthermore, a computing unit for controlling the device is provided.
  • By way of example, an external communication device is a backend server available from the Internet service providers for offering personalized services (such as automobile manufacturers), a general Internet application (such as card or navigation service providers), C2X communication devices or the like. The communication unit of the motor vehicle has in particular a gateway, which represents in the motor vehicle the communication interface with the participating in a wireless communication control devices of the motor vehicle. In particular, these control units can offer security functions, multimedia functions or service functions. The gateway is therefore integrated in the general communication network of the vehicle to which the control units are also connected.
  • The wireless communication in which the device for controlling intervenes may be a mobile data communication or WLAN. In principle, the invention is applicable to any type of communication. A mobile data communication can be realized for example as LTE, 3G / UMTS, Edge, GPS or the like. The WLAN function for the C2X communication can in particular after the Standard IEEE 802.11 P and ITS G5 (Intelligent Transport System) as DSRC (Dedicated Short Range Communication) be equipped.
  • For wireless communication, the communication unit also includes an antenna unit, which is a network access device that wirelessly connects the physical communication link to the external, i. H. outside the vehicle, communication devices manufactures. This antenna unit provides the hardware necessary for the communication and controls it within the scope of the communication protocol with an antenna control unit provided in the antenna unit. The antenna unit relates in particular to the physical layer and the data link layer of the OSI layer model with the functions defined therein. Such communication units with gateway and antenna unit are known and their basic function is not the subject of the invention.
  • The communication possibilities in modern motor vehicles due to the increasing networking of the control units operating in the motor vehicle with back-end servers, the traffic infrastructure, general Internet services or other vehicles mean that the privacy of the drivers is highly jeopardized and these services only work for data-aware users to be reluctantly accepted.
  • Object of the present invention is to provide a device that can ensure safe anonymization of the vehicle in the participation in the external communication.
  • This object is achieved with the features of claim 1. For this purpose, it is provided that the arithmetic unit of the device is set up after activation by the driver via the connection of the operating unit to monitor the data communication from the motor vehicle and restrict or completely prevent. By providing a central device for this purpose, the user or driver of the motor vehicle can influence and adjust his privacy centrally for all control devices by a simple actuation of the operating unit. This has the advantage that anonymization functions can also be switched on and off only in a situation-dependent manner, if necessary, in order temporarily to prevent the exchange of private data with external communication devices. This can be done while driving without having to set expensive safety precautions in the operating structure for the control units for individual control units.
  • According to a particularly preferred embodiment of the invention, the control terminal may have a connection to an antenna unit of the communication unit of the motor vehicle. The computing unit of the device is then designed to set up an antenna control unit of the antenna unit after activation by the driver by means of the operating unit in such a way that the transmission of information by the antenna unit is deactivated. The antenna unit is only able to receive data. This prevents any communication of data from the motor vehicle into the environment, so that no private data is transmitted any more. Only a communication for the production of, for example, bidirectional connections by means of WLAN is still allowed - in anonymous form. For example, it may be provided that the application-dependent private information is deleted in the communication protocol. This can be done by a appropriate access is provided to the memory areas provided in the communication protocol for the transmission of application-specific individualized data.
  • This setting allows the greatest possible security for the anonymization of the vehicle within the framework of the communication structure. However, then no personalized registration to external communication facilities, such as Internet services, more possible. However, other metafunctions within the vehicle that are not based on communication to personalized internet services remain readily available.
  • The invention can be implemented as a single, separate control unit that is used between the gateway and the antenna unit, or as a separate or integrated extension of the antenna unit or the gateway.
  • The invention allows the driver, by simply operating a switch in the car, the use of a dedicated vehicle key or a switching and / or selection function on a vehicle key or selecting an option in the vehicle menu, the transmission of private or such data, the conclusions to allow private data to reliably prevent independent of the active vehicle functions of each control devices.
  • To ensure that no internal information or external interference in the form of an attack on the data network ("hacker attack") can circumvent this anonymization, the special function for deactivating the transmission of information by the antenna unit in a protected memory area with a dedicated Access control or implemented on a separate security chip. As a result, a cancellation of the function on a hacker attack is largely excluded.
  • The arithmetic unit and the functions of the device according to the invention can also be implemented by means of a hardware security module known per se. Examples are z. As a secure hardware extension (SHE, Evita HSM, TPM, CTPM) or the like. Such an implementation may be performed by one of ordinary skill in the art.
  • It is also possible to implement the device according to the invention in the antenna control unit. The control terminal of the device is then formed within the computing unit of the antenna controller, for example by the computer bus. The operating connection can be realized in this case via the vehicle's own communication network for connecting an operating unit.
  • In this embodiment, it is particularly advantageous that the arithmetic unit of the device proposed according to the invention is implemented as virtualization in the antenna control unit. This is done in parallel with the application of the control of the antenna unit.
  • In this respect, the device according to the invention can also be implemented as a software module which uses corresponding connections of the antenna unit and / or the gateway, more generally the communication unit.
  • According to a further embodiment of the present invention, it can be provided that the control connection has a connection to a gateway and a connection to an antenna unit of the communication unit. In this case, the arithmetic unit of the device after activation is designed to work as a firewall and to filter out private information from the data stream. These functions are basically known for firewalls and can be implemented accordingly by the person skilled in the art.
  • For this purpose, the firewall can be implemented in the gateway itself, for example as virtualization, as a separate security chip or on a protected storage area with corresponding access control. A realization as a hardware security module is also possible.
  • Preferably, this device is integrated between the gateway and the antenna unit in the communication network of the vehicle so as to reliably detect all communication from the gateway to the antenna unit.
  • According to the invention, the firewall can be set up to not filter out private information necessary for authentication for logging onto server services from the data stream. For this purpose, the firewall can be designed, for example, parameterizable via the operating unit, so that the degree of anonymization can be predetermined by the user.
  • A particularly preferred embodiment provides that the device forms both a control connection to the gateway and a connection to the antenna unit and can be configured both as a firewall and for deactivating any transmitter activity in the antenna unit. Then the user can choose between two possibilities of anonymization depending on the situation.
  • The connection of the device to the operating unit can be designed to be connected to a human interface (HMI) designed user interface, which is adapted to allow activation of the device. Such user interfaces are often provided as universal interfaces in motor vehicles and can be used accordingly for this function.
  • Furthermore, the user interface can be designed as a switch, which is realized in software or hardware, or as a key recognition. The key recognition allows an automatic adjustment of the degree of anonymization by the device person-related to the driver, at least when a vehicle key is assigned to a driver.
  • The particular advantage of the present invention is that a central setting of anonymization is possible, wherein different degrees of anonymization can be set and this is valid for the entire vehicle communication with external communication devices, regardless of the individual functions of the control units. This possibility should greatly increase the acceptance of communication with external service providers. Show it:
  • 1 shows schematically the connection of a device according to the invention to the antenna unit;
  • 2 schematically shows the connection of a device according to the invention to the gateway.
  • The in the 1 and 2 illustrated embodiments of the invention are preferred embodiments, without the invention being limited to these embodiments.
  • In 1 is the device according to the invention 1 directly to the antenna unit 2 the communication unit of the motor vehicle connected. The antenna unit 2 comes with data through a gateway 3 the communication unit supplies, which represents a central communication interface with the participating in the communication control devices of the motor vehicle. These controllers are in the 1 and 2 not shown.
  • About the gateway 2 is also a control unit 4 to activate the device 1 provided via which the user can activate and deactivate the anonymization of the vehicle by pressing a switch or using a key.
  • The device according to the invention 1 acts directly on the antenna controller and inhibits the transmission of any information via wireless communication links to external communication devices. On the other hand, data necessary for establishing the communication can be transmitted because only in this way is it possible to receive data from external communication devices.
  • 2 shows another embodiment of a device according to the invention 5 entering the communication network between the gateway 3 and the antenna unit 2 is involved. The device 5 Can be used as a separate device or integrated into the gateway 2 or the antenna unit 1 be realized. In this respect, the functions of the device according to the invention 5 and the device according to the invention 1 especially when in the antenna unit 2 are integrated, can also be realized together.
  • The device 5 works as a firewall, the personalized data from the via the antenna unit 2 filters out data to be transmitted to the external communication device.
  • Examples of a concrete application of the device according to the invention 1 . 5 are explained below: An application example of a complete anonymization can be the prosecution of a fugitive by the police. In this case, the police usually want to prevent personalized information about the police vehicle consistently, so that the fugitive is not provided a technically simple way to locate the police forces, if necessary, from a greater distance. Such a location could be, for example, the location of the police vehicle or the information that the vehicle is a police vehicle. Such information should be available in external data networks at all. In such a case, it makes sense if the police vehicle switches off the transmission of all data to the environment (embodiment according to 1 ), and so remains invisible in the external communication network.
  • A case for the insertion of the device according to the invention 5 As a firewall between the gateway and the antenna can, for example, be the journey of a money-carrier. The cash transporter should not be able to be located, so that as personal information the position data of the money transporter are not transferred to the external data network. Nevertheless, it makes sense, for. For example, traffic services such as obtaining detailed traffic jam messages via a backend server service. In this case, the use of the device according to the invention is suitable 5 according to the representation of 2 ,
  • According to a particularly preferred embodiment, the user can adjust the degree of anonymization by the device according to the invention 1 . 5 either to the control unit of the antenna unit 2 acts as a firewall or filters the data stream to be transmitted.
