A process for the adaptation of the precontrol characteristic field of a volume flow is diesel - common - rail pump

摘要

In the method, in step (200) generates, at least nine initially - regression parameter. In a further step (202), at least nine suitable initial values for the fuel - injection quantity and the rotational speed of the selected. Furthermore, in step (204) on the basis of the selected regression parameter and the values for fuel - injection quantity and the rotational speed, the calculation of a corresponding vcv - position. Then, in step (206) a measured value added to. It is carried out in step (210) the calculation of nine new, in relation to the added measured value adapted regression parameters.Thereafter, the process is repeated from step (206) and, in turn, a further point (measured value) is determined, whereby with each iteration of the modeled characteristic field on the real characteristic diagram is approached.
