Method for operating drive unit, involves measuring sensor temperature of temperature sensor, and determining whether fluid temperature is greater than sensor temperature of fluid mass by temperature prediction model
The method involves determining fluid temperature by a temperature sensor (4) e.g. temperature-dependent resistor (5) or thermocouple element, in a region of a drive unit. Sensor temperature of the temperature sensor is measured, and a determination is made whether the fluid temperature is greater than the sensor temperature of fluid mass by a temperature prediction model (6). Control and/or regulation of the drive unit are performed based on the fluid temperature. An operational parameter is determined from a temperature value of the fluid temperature. Independent claims are also included for the following: (1) a device for operating a drive unit comprising a control device assigned to the drive unit (2) a computer program comprising a set of instructions for executing a drive unit operating method (3) a computer program product comprising a set of instructions for executing a drive unit operating method.
