ABSTRACT:
New algorithms for real-time estimation of the engine friction torque are developed. Engine friction torque can be estimated in a fuel cut-off state and at engine idle. New recursive and computationally efficient data-driven algorithms are developed for adaptation of the look-up tables. The algorithms make it possible to avoid driveability problems that could result from errors in estimating engine friction torque.
