A method for generating a signal (TAn) responsive to the induction air temperature of an internal combustion engine. The signal (TAn) for the induction air temperature is determined from a signal (TMot) for the temperature of the internal combustion engine, from a signal (TU) for the ambient temperature, and from a correction factor K. Correction factor K is a function of a signal (mL) and/or a vehicular speed signal (v), signal (mL) representing either the induction air quantity or the air mass of the internal combustion engine. To enable the most accurate possible simulation of induction air temperature, even under changing operating conditions, the signal (TAn) for the induction air temperature is filtered, it being possible to variably select the time constant (ZK) of the filter in response to rising and falling induction air temperatures.
