Abstract:
A vehicle comprising:a drivetrain including an internal combustion engine having a first output shaft, a transmission operatively connected to said first output shaft, said transmission having a plurality of gear ratios, and a rotating propulsion member operatively coupled to said transmission; and a control system for managing a torque of said drivetrain, said control system including a first sensor providing an engine speed signal indicative of a rotational speed of said first output shaft, a second sensor providing a vehicle speed signal indicative of a rotational speed of said rotating propulsion member, and a controller responsive to said engine speed signal and said vehicle speed signal to generate a gear ratio signal as an indication of an engaged gear ratio of said plurality of gear ratios, a torque limit signal as an indication of a torque limit of said engaged gear ratio, a maximum torque signal as an indication of a maximum torque that is transmittable by said output shaft to said transmission, a maximum fuel signal as an indication of a maximum quantity of fuel required for said output shaft to transmit said maximum torque to said transmission, and a first fueling meter signal as an indication of a first quantity of fuel to be supplied to said internal combustion engine, wherein first fueling meter signal is determined as a function of said torque limit signal, said maximum torque signal, and said maximum fuel signal.
