Abstract (en)
[origin: EP0187926A2] In the system, values which can be read out from a characteristic map can be corrected and the data for the correction are only formed and made available when the readiness for operation of at least part of the system has been ensured. This applies particularly with respect to the supply voltage of the elements concerned. The illustrative embodiment depicted in the flow diagram relates to the formation of injection signals via the formation of a basic signal with subsequent learnable correction, the correction data being updated and read into the corresponding memory only as long as the supply voltage has exceeded certain values. <IMAGE>
