Claim 0:
1. A method for determining at least one temperature compensation parameter for compensating temperature effects on measured values of a sensor system, the sensor system including a sensor configured to acquire measured values of a sensor measuring variable, a temperature sensor configured to acquire a temperature of the sensor, and a signal processor configured to determine at least one temperature compensation parameter and to compensate temperature effects on the measured values of the sensor, the method comprising the following steps:
monitoring a temperature of the sensor and determining whether a current temperature of the sensor corresponds to a reference temperature for which at least one reference measured value of the sensor measuring variable is known
and whether the current temperature of the sensor lies within a predefined temperature range;
acquiring at least two different temperature values of the sensor within the predefined temperature range and acquiring respective associated measured values of the sensor measuring variable when the current temperature corresponds to the reference temperature;
determining at least one temperature compensation parameter based on the at least one reference measured value of the sensor measuring variable, the at least two different temperature values, and the associated measured values of the sensor measuring variable.
