  • Method and apparatus for controlling an internal combustion engine
    Patent number: 4501250
    Abstract: For controlling an internal combustion engine at least first and second control maps are provided in which first and second control variables are stored respectively, which are addressible in response to different combinations of output parameters of the engine. First and second weighting factors are derived for weighting first and second control variables which are derived respectively in response to a first and a second combination of engine output operating parameters. The weighted first and second control variables are summed to derive a combined control variable for controlling one of the input operating parameters.
