Zusammenfassung:A method for determining the existence of a "short time" type state within a vehicle control assembly 10. The method requires the measurement of the temperature 59 of engine coolant 16 at a first time 61 and the determination and/or the inferential creation of the temperature 60 of the engine coolant 16 at a second and later time 62. A "short time" type state is identified when the temperature 60 at the second time 62 is greater than or equal to the temperature 59 at the first time 61.
