Definitions

  • the invention relates to a motor vehicle interior lighting.
  • newer motor vehicles increasingly have so-called ambient light functions, which ensure discreet illumination of the interior.
  • the use of this type of lighting makes it easier for passengers in the vehicle to orient themselves and creates an individual and homely atmosphere.
  • the invention is based on the object to provide a striking and variable automotive interior lighting.
  • a motor vehicle interior lighting comprises an in particular rod-shaped light guide and at least one light source, which is embodied and arranged such that light from the light source is coupled into the light guide at one end of the light guide.
  • a control device coupled to a motor vehicle system bus is provided for controlling the light source. By this control device, the light source is controlled such that the light of the light source is changed depending on transmitted via the system bus bus data in terms of color and / or brightness.
  • the light source can be controlled differently when the vehicle is moving, with positive acceleration unlike negative acceleration, with open doors other than closed doors, with engine-off unlike engine on, with active electric drive unlike active internal combustion engine drive, with lateral acceleration other than without lateral acceleration, with high temperatures other than at low temperatures, with high engine speeds unlike with low engine speeds, with more vehicle occupants than with less vehicle occupants, with a large distance to an obstacle other than at small distance to an obstacle, etc.
  • the bus data comprises vehicle state data (data which describe, for example, the vehicle state, a vehicle component state or the vehicle environment) which is output by the control device in color and / or brightness information (for example information in the HSV color space or corresponding light source control signals, for example pulse width modulation parameters or lighting parameters). be implemented. Based on the color and / or brightness information, the light of the light source is then changed in terms of color and / or brightness.
  • vehicle state data data which describe, for example, the vehicle state, a vehicle component state or the vehicle environment
  • brightness information for example information in the HSV color space or corresponding light source control signals, for example pulse width modulation parameters or lighting parameters.
  • a conversion of color and / or brightness information in a color space into light source control signals can optionally be effected by the control device itself or a conversion unit coupled thereto.
  • the bus data already includes color and / or brightness information (for example, information in the HSV color space or corresponding light source control signals, for example pulse width modulation parameters or lighting parameters).
  • An implementation, for example, of vehicle status data in color / brightness information thus takes place in this variant not in the control device but in another unit coupled to the motor vehicle system bus, for example a second control device. The color and / or brightness information can then be sent from the second control device to the motor vehicle system bus.
  • the motor vehicle system bus is coupled to an interface, in particular a radio interface, such that color and / or brightness information can be transmitted to the motor vehicle system bus via the radio interface.
  • an interface in particular a radio interface
  • color and / or brightness information can be transmitted to the motor vehicle system bus via the radio interface.
  • an external device such as a mobile phone, a portable computer, etc.
  • the color / brightness information is then transmitted via the interface to the automotive system bus to drive the light source based thereon.
  • vehicle state data can be transmitted via the interface to the external device in order to be able to use the vehicle state data in the external device for generating the color / brightness information.
  • the external device may have limited or full authority to access the vehicle system bus or bus data on the vehicle
  • Automotive system bus obtained to receive vehicle condition data and / or to send and / or receive color and / or brightness information.
  • An implementation of the invention in practice is particularly simple when the light source at least one RGB LED or an organic light emitting diode ode whose brightness and / or color are adjusted for example via the current or a pulse width modulation.
  • Figure 1 shows a simplified schematic diagram of a
  • FIG. 1 shows a rod-shaped optical waveguide LL into which light of a first RGB light-emitting diode LQ1 is coupled at the first end, and light of a second RGB light-emitting diode LQ2 at the opposite, second end
  • LQ1, LQ2 light coupled into the light guide LL can be adjusted via the control device (footwell module) FRM, for example via the current supply of the RGB LEDs LQ1, LQ2 or based on a pulse width modulation.
  • the control device FRM can be coupled, for example, with appropriately set constant current sources or have corresponding PWM outputs.
  • the control device FRM is coupled to a motor vehicle system bus BUS, for example a CAN BUS, a LIN BUS or a FLEXRAY BUS.
  • the control device FRM can receive bus data via the motor vehicle system bus BUS.
  • the bus data may include, for example, vehicle status data.
  • the vehicle condition data is derived from another force vehicle subsystem, such as a parking assistance system PDC generated.
  • the vehicle state data in color and / or brightness information for the light-emitting diodes LQ1.LQ2 can be implemented.
