Abstract: A computer-implemented method for recalibrating a trained data-based calibration model for use in a sensor system for measuring one or more physical variables is disclosed. The data-based calibration model is formed as a neural graph network which is trained to output an output vector comprising one or more output variables and a plurality of auxiliary variables, depending on a sensor state graph representing a sensor state.

Abstract: A method for calibrating a sensor of a sensor system. A plurality of sensors structurally identical to the sensor of the sensor system and a general sensor model are provided. An inner optimization step is subsequently carried out for each of the structurally identical sensors. During the inner optimization step, a sensor-specific sensor model is initialized using the general sensor model and a sensor-specific model parameter is subsequently optimized based on measured data of the sensor. The sensor-specific sensor model is adapted with the aid of the sensor-specific model parameter. An outer optimization step is then carried out. In this step, the sensor-specific sensor models adapted for each sensor are used in order to optimize the general sensor model. The general sensor model is stored in a memory of the sensor system.
