Definitions

  • the invention relates to a method for controlling vehicle functions by a remote control, wherein signals are transmitted wirelessly between the remote control and a station in the vehicle, and wherein a data transmission rate depends on a distance between the remote control and station in the vehicle. Moreover, the invention relates to a system for controlling vehicle functions and a computer program or computer program product.
  • EP 2 719 556 A1 discloses a control device for an electronic brake system in a trailer. With the control unit and a height adjustment of a pneumatic suspension having trailer is possible. At the same time, the control unit is linked to other devices or sensors via a CAN bus. This includes a WLAN module, which can build a wireless connection to a WLAN-enabled device outside the vehicle.
  • devices such as laptops, smartphones and navigation systems, which are to be connected wirelessly, are mentioned. As a result, a control of functions of the control unit in the vehicle using a smartphone is possible, which has the function of a remote control.
  • the object of the present invention is to provide a method and a system with which it can be ensured in another way that the remote control is located in the transmission of signals at a sufficiently short distance from the vehicle.
  • the inventive method has the features of claim 1.
  • the data transmission rate is determined and that at a data transmission rate below a defined limit value
  • the vehicle functions to be controlled are no longer or only limitedly executed, and / or
  • the remote control issues warning signals.
  • the control of the vehicle functions is thus at least limited.
  • signals which are perceptible via the remote control, in particular by the user are output.
  • the user recognizable indication signals are understood all signals that are perceptible by human senses, ie in particular visible, audible or tactile signals.
  • the remote control is understood all signals that are perceptible by human senses, ie in particular visible, audible or tactile signals.
  • any wireless transmission technique is suitable in which the data transmission rate also depends on the distance.
  • the determination / monitoring of the data transmission rate takes place continuously or at defined time intervals.
  • the data transfer rate is monitored by the remote control.
  • the determination / monitoring of the data transmission rate can also be done by the station.
  • the remote control no longer transmits signals to the station below the defined limit value of the data transmission rate or only to a limited extent.
  • a limited transmission consists, for example, in that only signals for uncritical control measures are transmitted, such as signals for changing a lighting of the vehicle or signals for requesting vehicle data.
  • the provision of vehicle data is also understood as the control of vehicle functions. This can on the one hand immutable vehicle data for
  • the wireless transmission of the data takes place via WLAN, in particular according to the IEEE 802.1 1 standard, successor standards for this and / or extensions of the standards.
  • the station operates in one mode as an access point while the remote control is connected as a WLAN client to the station.
  • other standards for a digital radio transmission can be applied, such as Bluetooth or
  • the remote control is a telephone, in particular a smartphone.
  • the latter is provided with suitable software, a so-called app for controlling the vehicle functions.
  • defined data packets are transmitted as signals between remote control and station for the determination of the data transmission rate, wherein the transmission of the defined data packets is repeated after defined time intervals.
  • the data transfer rate may also depend on the size of the data packets.
  • these are data packets which are sent exclusively for determining the data transmission rate and have no additional content.
  • the data transfer rate can look like this the number (and size) of the transmitted data packets per unit time are determined.
  • the transmission of the defined data packets is repeated in relatively short time intervals, approximately every one to two seconds. This time interval should be sufficiently short, since the user with the
  • Remote control can not move arbitrarily fast.
  • the system in particular for carrying out the aforementioned method, has the features of claim 7.
  • the system is provided with a remote control for the wireless transmission of signals, with a station in the vehicle for the wireless transmission of signals and with means for determining a
  • the vehicle functions to be controlled are no longer or only limitedly executed, and / or
  • the means for determining the data transmission rate are components of the remote control.
  • the remote control may have a corresponding radio module, optionally in conjunction with a software for controlling the remote control.
  • the means for determining the data transmission rate may be components of the station in the vehicle.
  • the remote control includes a WLAN module, as well as the station. Accordingly, the wireless transmission of the signals in the context of a WLAN connection according to the standard IEEE802.1 1 and / or successor standards or extensions thereto.
  • the remote control is a telephone, in particular a smartphone.
  • Modern smartphones or mobile phones are already equipped with a WLAN module.

  • the subject of the invention is also a computer program, computer program product or app for carrying out the explained method and / or for the illustrated system.
  • the data transmission rate in the sense of the invention is understood to be any measurable data rate.
  • the data transmission rate is a gross data rate, that is to say a data throughput including control data.
  • a net data rate denotes the data throughput of pure user data.
  • the maximum gross data rate of a WLAN connection according to the IEEE 802.1 standard is 1 g
  • the limit for the data transmission rate should preferably be between 10 and 20 Mbit / s as the net data rate.

Procedures are also implemented in the software as long as the user removes them from the station 14 with the remote control 15 and the data transmission rate drops below the defined limit. It is first issued on the remote control 15 a warning, such as an optical or acoustic signal or vibration. at If the data transmission rate continues to drop, control of the vehicle functions will no longer be permitted. Conversely, the remote control 15 can signal the exceeding of the defined limit of the data transmission rate when approaching the station 14 and allow the control of the vehicle functions.
