Electronic control unit for a motor vehicle

摘要

A control unit has a circuit support, on which electrical and/or electronic components of an electronic circuit of the control unit are disposed. The circuit support is composed of a temperature-resistant ceramic material, and on it there is applied at least one resistive track made of a material whose electrical resistance is temperature-dependent. The resistive track is connected to an evaluation circuit that determines the temperature using resistance values measured on the resistive track. The circuit support is in thermally conductive contact with the environment that is to be taken into consideration.
