Method and apparatus for controlling a power delivery system having a continuously variable ratio transmission
A system for controlling the operation of a power delivery system including an engine and a continuously variable ratio transmission coupled to the engine for delivering power from the engine to an output shaft. The engine has fuel delivery means for delivering a variable quantity of fuel thereto. The power delivery system is controlled by command means for commanding a desired power delivery system performance, wherein the engine is maintained along an ideal operating line as a function of engine speed. The system comprises: actual system performance measuring means for measuring the actual performance of the power delivery system; ratio control means operatively coupled to the command means and the actual system performance measuring means for controlling the ratio of the transmission as a function of the desired system performance commanded by the command means and the measured actual system performance, the speed of the engine varying as a function of transmission ratio; command power controller means for providing a signal representing accelerator pedal position; and control means coupled to the command power controller means which includes compensating means for providing a compensating signal as a function of the signal representing accelerator pedal position, the compensating means includes a compensator and a gain controller and wherein the fuel delivered to the engine by the fuel delivery means is dependent on the compensating signal.
