The invention relates to a control module for use in motor vehicles, comprising a plurality of signal inputs, a plurality of signal outputs, a central storage unit which is connected to at least one functional unit for further processing incoming signals. A signal identification number can be assigned to the at least one signal coming into the central storage unit such that the signal can be identified and further used by the at least one functional unit. The at least one functional unit can be exchanged in a modular manner. The invention additionally relates to a system for configuring the control module, to a method for using the control module, and to a motor vehicle control unit comprising the control module.

Control module, configuration system, method for use and motor vehicle control unit

A method for obtaining PWM values for an LED module having n LED chips from various color ranges, wherein n&#x3e;1, wherein for each LED chip a PWM value for producing a target color value is obtained, is characterized in that a calibration measurement is performed in which the wave lengths (&#x3bb;, &#x3bb;, &#x3bb;) and/or the standard color proportion values ((x,y), (x,y), (x,y)) and possibly the luminous flux values of the individual LED chips are determined at a calibration temperature (T), PWM control points are obtained, where each PWM control point contains a PWM value for each of the n color ranges of the LED module, during operation of the LED module a value that depends on the present temperature (T) of the LED module, in particular the present temperature (T) itself, is determined, and a first and a second PWM control point are assigned to this temperature-dependent value, and the PWM values for producing the target color value are obtained through interpolation between the assigned PWM control points. This makes it possible to realize a precise color mixture in the LED module in a cost-effective way, with little computing power, despite temperature fluctuations (and possible electric current fluctuations).
