Method for applicative self-calibration of a measuring arrangement necessary for locally precise automatic addressing of bus subscribers in a differential CAN bus system , wherein the bus subscribers are linearly arranged along a CAN bus and are each connected to a CANH line by way of a first connection and to a CANL line of the CAN bus by way of a second connection, and a CAN bus master is arranged at the start of the CAN bus and a termination resistor is arranged at least at the end of the CAN bus , wherein the CAN bus master and the termination resistor respectively connect the CANH line and the CANL line to one another, characterized in that the method has the following steps of: - measuring three differential voltage values during a dominant bus state at each bus subscriber , wherein - a first differential voltage value V 0V of GND with respect to GND is measured at each bus subscriber at the same time, - a second differential voltage value V CANH of the CANH line with respect to GND is measured at each bus subscriber at the same time, - a third differential voltage value V CANL of the CANL line with respect to GND is measured at each bus subscriber at the same time; - compensating for an individual offset error for each bus subscriber by respectively subtracting the first V 0V differential voltage value from the second V CANH differential voltage value and from the third V CANL differential voltage value of the respective bus subscriber ; - compensating for an individual gain error for each bus subscriber by means of a correction factor k korr , wherein the correction factor k korr is determined from a fixed bus reference value V CMRef and the compensated V* CANH and V* CANL differential voltage values according to k korr = 2·V CMRef /(V* CANH +V* CANL ); - determining a self-calibrated differential voltage value V AA according to V AA = (V CANH - V CANL ) · k korr = (V CANH - V CANL ) · (2·V CMRef ) / (V* CANH + V* CANL ) by means of each bus subscriber . - measuring three differential voltage values during a dominant bus state at each bus subscriber , wherein - a first differential voltage value V 0V of GND with respect to GND is measured at each bus subscriber at the same time, - a second differential voltage value V CANH of the CANH line with respect to GND is measured at each bus subscriber at the same time, - a third differential voltage value V CANL of the CANL line with respect to GND is measured at each bus subscriber at the same time; - compensating for an individual offset error for each bus subscriber by respectively subtracting the first V 0V differential voltage value from the second V CANH differential voltage value and from the third V CANL differential voltage value of the respective bus subscriber ; - compensating for an individual gain error for each bus subscriber by means of a correction factor k korr , wherein the correction factor k korr is determined from a fixed bus reference value V CMRef and the compensated V* CANH and V* CANL differential voltage values according to k korr = 2·V CMRef /(V* CANH +V* CANL ); - determining a self-calibrated differential voltage value V AA according to V AA = (V CANH - V CANL ) · k korr = (V CANH - V CANL ) · (2·V CMRef ) / (V* CANH + V* CANL ) by means of each bus subscriber . <EOS>
