Abstract
A system and method for providing engine torque load in real time. The system includes a sensor to determine, in real time, a clutch state of an alternator clutch and a controller for determining an alternator torque value and applying the alternator torque value to the engine torque load in real time.
Claims17
A system for providing, in real time, an engine torque load to an engine, said system comprising:
- a sensor that determines, in real time, a clutch state of an alternator clutch;
- and
- a controller adapted to:
- calculate an alternator torque value;
- and
- apply the alternator torque value to the engine torque load in real time.

estimating an alternator rotor speed when the engine revolutions per minute decreases.
A method of updating an engine torque load for a vehicle, said method comprising:
- determining by a sensor a clutch state of an alternator clutch;
- determining by an engine control unit an alternator torque value;
- and
- applying by an engine control unit the alternator torque value to the engine torque load when it is determined that the clutch state corresponds to an alternator clutch engaged state.
