Definitions

  • the invention relates to a method for transmitting information to control devices in a motor vehicle via an optical interface.
  • the invention has for its object to provide a method that allows a simplified and cost-effective transmission of information to a vehicle network or to one or more control units of a motor vehicle. This object is achieved by a method having the features of claim 1.
  • Advantageous embodiments and further developments are the subject of dependent claims, wherein combinations and developments of individual features are conceivable with each other.
  • An essential idea of the invention is to realize the transmission of information, for example for parameterization or diagnosis, to the vehicle network or to individual or a plurality of control units arranged in the vehicle via an optical interface, wherein at least one of the control units is not part of the driver assistance system.
  • Driver assistance systems is.
  • the optical interface is, in particular, a camera already present in the vehicle, which is used, for example, for a driver assistance system.
  • a camera already present in a motor vehicle and used for other purposes is used to communicate with the vehicle network or to transmit data.
  • a significant advantage of the method according to the invention is that for the transmission of information no special OBD socket more in the vehicle must be present, whereby costs and installation space can be saved.
  • the inventive method increases the flexibility, since no plug standards must be complied with. Thus, expensive communication devices or physical data lines can be dispensed with, and in particular new applications for local and cost-effective communication with the vehicle infrastructure are opened up.
  • the camera systems currently installed in the vehicle usually already provide extensive hardware resources and image processing algorithms, resulting in additional cost efficiency.
  • information is sent to one or more control units of a motor vehicle.
  • the information may be, for example, one or more control commands and / or data for the parameterization.
  • an optical interface preferably a camera, which is arranged on the motor vehicle serves as a means for receiving the information for the one or more control units.
  • the camera may be one already in the Motor vehicle existing camera, which serves as a detection means, for example for detecting the vehicle environment and / or interior, for one or more driver assistance systems.
  • the camera can be arranged in the vehicle interior behind a windshield, preferably in the wiper area of a windshield wiper, for example with a view towards the road ahead in the direction of travel of the vehicle.
  • the transmitted information is one or more control commands, eg diagnostic commands, which cause predefined reactions in one or more control devices, for example for
  • the information sent can also be, for example, information or data, for example parameterization data that is stored on one or more control units.
  • at least part of the control devices and / or the driver assistance systems are interconnected via a network, for example a bus system or CAN bus (Controller Area Network).
  • the camera preferably comprises an evaluation unit for evaluating the images obtained via the camera and for forwarding data, information and / or control commands.
  • the camera or the evaluation unit is also connected in particular to the network and can send information via the network to one or more control devices and / or to one or more driver assistance systems.
  • the information is encoded as a pattern or symbols.
