    摘要： In a method and a device for adapting the injection agent supply for an emission control system, the following steps are carried out: a) setting of a agent pressure target value in the line upstream of the pump in relation to the ambient pressure; b) opening of the pressure relief valve for a predetermined time t; c) determining the pressure difference between the target and the injection agent pressure, caused in step b), immediately after step b); d) setting a target value for the agent pressure in the line downstream of the pump in relation to the exhaust gas pressure in the system; e) opening of the injector for a predetermined time t; f) determining the pressure difference between the target and the agent pressure, caused in step e), immediately after step e); g) comparing the pressure differences from steps c) and f); and h) optional adaptation of the injector opening time.

    摘要： In an adaptive positioning method for an actuator, in particular, for a throttle butterfly on an internal combustion engine, during the adaptive positioning method, after a request for a set position and selection of a pilot value a corresponding pilot position for the actuator is adopted. The pilot position is adjusted until said position corresponds to the requested set position. The control value actually required or this set position is subsequently measured and recorded as corrected pilot value for the corresponding set position.

    摘要： A method for adapting a measured value (MW1) of an air mass sensor comprises the steps pf determining a correction value (KW) in the event of predetermined operating conditions (BB1), namely depending on the measured value (MW1) and a comparative value (VW) which in turn depends on at least one additional measured value (MW2) of a second sensor. An adaptation value (AD1) is adapted depending on the correction value (VW), on the duration (D_AD1) since the last determination of the adaptation value (AD1) and on the change of the adaptation value (AD1) since the last adaptation of the adaptation value (AD1). Subsequently measured values (MW1) are corrected using the adaptation value (AD1).
