摘要

A system (12) and method for determining a value for a control variable for an engine (10) are provided. The system (12) includes an electronic control unit (ECU) (62) configured to obtain a plurality of pairs of programmed timing values for the opening and closing, respectively, of an intake valve (30) and exhaust valve (32) in a cylinder (14) of the engine (10) responsive to different sets of engine operating conditions. The ECU (62) is further configured to obtain a corresponding plurality of conditional values for the control variable responsive to the speed of, and load on, the engine (10) and the plurality of pairs of programmed timing values. Finally, the ECU (62) is configured to determine through interpolation the value for the control variable responsive to the plurality of conditional values. The system and method enable accurate determination of engine control variables during transient conditions using existing engine data.
