Abstract
Torque being produced by a turbocharged internal combustion engine () during acceleration under load is calculated by processing () a value for actual boost MAP and a value MAP_NOMINAL selected from a map () that contains data values for boost that would prevail during steady state engine operation at a respective speed with the engine developing a respective torque. The selection is made using engine speed N and estimated torque TQI_SP that possesses some inaccuracy due to some disparity between the data value for actual boost and the data value selected from the map. The selection yields a boost disparity value that is used along with the estimated torque to select from a torque map () a value for calculated torque that provides a better correlation with actual torque than does the estimated torque during acceleration.
