ABSTRACT:
An engine control system for use in connection with vehicles and the like allows the engine speed to be modified using the torque load from the electrical generator. The engine is subject to a torque load from a generator coupled to the engine. The controller compares the desired speed to the actual speed of the engine to determine an error value, and the torque load of the generator is modified (increased/decreased) based on the error value such that the absolute value of the error value is reduced. The generator control is combined with and arbitrated with respect to traditional spark control methods, thus reducing the need for spark timing that is substantially retarded from the mean best timing (MBT) setting. The electrical generator can operate in either voltage control mode or field duty cycle control mode, depending upon various conditions.
