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.
- the information may be displayed as a barcode (eg barcode, barcode).
- the data coded as a barcode can be recognized by means of the optical interface and further processed electronically via an evaluation unit, which is used to evaluate the images obtained via the camera.
- the information is coded by means of colors.
- a specific first color sequence which is detected by the camera and evaluated by an evaluation unit, which is used to evaluate the images obtained via the camera, be assigned to a specific control device in the vehicle, whereupon the evaluation unit a second color sequence, in particular in the direct Connection to the first color sequence is received, which assigns to the first color sequence specific controller.
- a specific control command is preferably coded for the control unit determined by the first color sequence, which is sent to the control unit, for example, via the network.
- the information which is received via the optical interface and sent to one or more control devices in the motor vehicle is encoded by means of brightness modulation.
- a specific sequence of brightness values which is detected by the camera and evaluated by an evaluation unit, which is used to evaluate the images obtained via the camera, be assigned to a specific control device in the vehicle.
- the evaluation unit can then assign a second sequence of brightness values, which is received in particular immediately after the first sequence of brightness values, to the previously determined control unit.
- a specific control command is preferably coded for the specific control unit, which is sent to the control unit, for example, via the network.
- the information which is received via the optical interface and sent to one or more control devices in the motor vehicle is coded by means of human gestures.
- the encoded information is deliberately introduced into the detection range of the camera. If the information is coded by means of bar codes and / or symbols and applied, for example, to paper, they can be held in close proximity to the camera so that it can capture the information. If the information is coded by means of color code and / or by means of brightness modulation, these can be transmitted, for example, by a special transmitting unit different color signals and / or for emitting light with different brightness values or light of different intensity are sent, wherein the transmitting unit is introduced in a short distance in front of the camera and with transmission direction opposite to the viewing direction of the camera, for example, in which the transmitting unit from the outside in front of the Windshield is held in the direction of the camera.
- any type of information that can be processed by one or more control units in a motor vehicle can be sent to the one or more control units via the described method.
- the distance or the distance to the motor vehicle from where, for example, the encoded information in the detection range of the optical interface or the camera are introduced, can be chosen arbitrarily and depends in particular on the type of coding and the resolution of the camera. Further advantages and optional embodiments will become apparent from the description and the drawings. Embodiments are shown in simplified form in the drawings and explained in more detail in the following description.
