Definitions
- the invention relates to a device for controlling electrical and / or electronic components of a motor vehicle module, in particular an interior light and / or outdoor light such.
- the invention relates to a motor vehicle module with a plurality of electrical and / or electronic components, in particular an interior light and / or outdoor light such. a rear light module of a car.
- motor vehicle modules such as the various light modules are becoming increasingly complex. Especially in the field of "light” is increasingly in the recent past over to dynamic functions such. B. use the "wiping turn signals” or the so-called “coming home” application. It is advantageous to exploit the fact that the individual exterior and interior light functions of a vehicle are realized by a plurality of LEDs or OLEDs. Dynamic effects can now be realized in a comparatively simple manner in terms of hardware in that the multiplicity of light sources which have such a motor vehicle light module are activated in different ways.
- the plurality of components of a motor vehicle module that is, for example, the plurality of LEDs assigned to the individual light functions or OLEDs of a backlight module, for example, are advantageously connected to a drive unit of the module via a communication bus or are in communication communication with the drive unit via the communication bus.
- the drive unit also includes a voltage converter for supplying in particular LED drivers of a light module.
- differential two-wire communication bus systems have proven themselves. The information signals are transmitted between the drive unit and the participants as a voltage difference between the two bus lines, whereby a greater signal security and lower susceptibility is achieved.
- Such two-wire bus lines are known in principle. The problem is that the hardware complexity for such two-wire bus systems and their participants is not negligible. In particular, in terms of the cost of disadvantage is the fact that the participants must have relatively precisely working clock that work in sync with each other.

- bit streams sent by the drive unit have synchronization bits for synchronizing the clocks of the
- the approach according to the invention combines the advantages of a differential two-wire communication bus with the advantages of using asynchronous, digital, serial interfaces via which the individual subscribers or the individual components are connected to the two-wire communication bus.
- UART Universal Asynchronous Receiver Transmitters
- the protocol of the differential two-wire communication bus used according to the invention comprises elements such as are known, for example, from single-wire communication buses whose subscribers have standardized and cost-effective UARTs.
- the invention can be used in particular in the context of digital interfaces for robust and high-speed transmission of data via a two-wire cable connection between LEDs equipped with LEDs for example tail light and interior light within a luminaire with a data rate of up to 500 kbit / s.
- the symmetrical transmission is used by means of a differential high-speed two-wire bus system for the purpose of transmitting a simple serial protocol and thus to reduce the hardware digital effort.
