Abstract:
An automotive vehicle comprising:a powertrain that includes a combustion engine having an output shaft powering a drivetrain to propel the vehicle:at least one ambient parameter variable input source representing a respective ambient parameter useful in deriving gross torque output of the combustion engine;at least one operating variable input source representing a respective operating parameter useful in deriving a reduction in gross torque output of the combustion engine due to operation of the combustion engine;a processor for deriving net torque output of the combustion engine at the output shaft of the engine for powering the drivetrain to propel the vehicle by processing at least a respective signal correlated to the at least one ambient parameter variable input source to derive gross torque output of the combustion engine, processing at least a respective signal correlated to the at least one operating parameter variable input source to derive a reduction in gross torque output of the combustion engine due to operation of the combustion engine, and processing the derived gross torque output and the derived reduction in gross torque output to derive the net torque output; anda utilization device in the drivetrain whose operation at least at times utilizes the derived net torque output.
