Internal combustion engine revolution rate regulation involves using different characteristics for input parameter in different engine modes, changing between characteristics when condition fulfilled

摘要

The method involves computing a control error from a desired-actual value comparison, deriving a desired injection quantity, computing a second desired injection quantity from the first desired injection quantity and a further input parameter by minimum value selection. Different characteristics are used for the input parameters in different engine modes. A changeover between characteristics occurs when a changeover condition is fulfilled. The method involves computing a control error from a desired-actual value comparison for revolution rate, computing a desired fuel injection quantity from the first control error and computing a second desired fuel injection quantity for revolution rate regulation from the first desired fuel injection quantity and a further input parameter using a minimum value selection. Different characteristics are used for the input parameters in different engine operating states and a changeover between the characteristics occurs when a changeover condition is fulfilled.
