Method for the locally precise automatic addressing of bus subscribers with applicative self-calibration 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 of the CAN bus 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 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, the method having the following steps of: - switching on and/or resetting the CAN bus system; - signalling an auto-addressing mode, by means of the CAN bus master, to the bus subscribers which set the auto-addressing mode; - 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; - simultaneously transmitting the self-calibrated differential voltage values V AA from each bus subscriber to the CAN bus master, wherein each bus subscriber repeats the transmission of its differential voltage value V AA until the last bit of the latter has been transmitted to the CAN bus master without conflict, wherein a bus node address is determined for each bus subscriber from the sequence of differential voltage values V AA transmitted without conflict by means of an assignment rule known and stipulated in the CAN bus system. - switching on and/or resetting the CAN bus system;
