Method for determining the temperature of a motor vehicle passenger compartment, device for carrying out the method and temperature sensor

The involves determining air circulation in front of a measurement point for use as a weighted correction value, determining and storing the sensor reaction with the air at rest in an adaptive measurement, applying a signal to an additional heating element, which is read out at the sensor as a step response and determining the presence/absence of an air flow from the difference between the step response and adaptively determined reaction. The method is based on a solar radiation parameter determined at a sensor and/or a surface temperature at the measurement position at a further sensor. It involves determining air circulation in front of the measurement point, which is fed into the determined solar radiation as a weighted correction value, determining and storing the sensor reaction with the air at rest in an adaptive measurement, applying a signal to an additional heating element, which is read out at the sensor as a step response and determining the presence/absence of an air flow from the difference between the step response and the adaptively determined reaction. Independent claims are also included for the following: (a) an arrangement for implementing the inventive method (b) and a temperature sensor for determining the interior temperature especially of a motor vehicle passenger compartment.
