Abstract: The invention is directed to a system for controlling operating sequences in a motor vehicle having an electronic circuit controlling (open loop and/or closed loop) the operational sequences. A temperature detecting device is provided which is mounted so as to be in thermal contact at least with parts of the electronic circuit and detects a temperature value representing the temperature of this part. A determination is made whether the detected temperature value of at least one of at least two different threshold values is exceeded. Different measures are then initiated in dependence upon which of the different threshold values is exceeded. The system considers the occurrence of high temperatures in that the system itself detects a damaging temperature and reacts appropriately by different measures to different high temperatures.
