ABSTRACT:
A process for the model-supported simulation of the coolant temperature in the case of a vehicle is provided. Conventionally, two temperature sensors are used for determining the coolant temperature, in which case one exists only for determining the temperature when an engine is switched off. Such an additional sensor is cost-intensive and should be avoided. The process avoids using an additional sensor by detecting the coolant temperature at the point in time of the switching-off of the driving engine. A current coolant temperature is continuously calculated while including vehicle-specific data using a temperature model. As an alternative, the current coolant temperature is not continuously calculated, but rather is calculated from a point in time as of which a theoretically determined coolant temperature falls below a specific value.
