Abstract
A torque calculator and method for providing real time data that measures net torque output of a running engine in a motor vehicle. Gross torque production is calculated using engine speed and fueling data. Torque losses due to accessories, pumping, and friction are calculated and subtracted from gross torque production, and inertial torque is also accounted for to yield engine net running torque. The engine net running torque data and engine speed data are processed according to a filter algorithm that compensates the engine net running torque data for engine speed. Transmission shifting is controlled by the speed-compensated engine net running torque.
