New Strategy for Torque Estimators

In automotive powertrain control strategies, engine torque estimators are preferred to expensive sensors for obvious economic reasons. At the “Group for Research on Automatic Control Engineering“ (GRACE) laboratory at the Università del Sannio in Benevento, Italy, engineers developed a completely new strategy, called “nicely nonlinear torque estimator”. This is an algorithm that can be ef.ciently used for engine-transmission or engine-vehicle integrated control strategies. The tests con.rming the performance of the proposed algorithm were run with dSPACE prototyping and hardware-in-the-loop systems.
