20110183810METHOD AND SYSTEM FOR ADAPTIVE CONTINUOUSLY VARIABLE TRANSMISSION GEAR RATIO CONTROL - An automobile comprising a continuously variable transmission (“CVT”) system including an acceleration input device, a CVT, and a processor. The acceleration input device generates acceleration input data indicating an amount of change in the acceleration input device, and a rate of change in the acceleration input device. The CVT includes a power source and a transmission output system. The power source operates at a transmission input speed, while the transmission output system operates at a transmission output speed. The transmission input speed over the transmission output speed comprises a gear ratio. The processor analyzes the acceleration input data to determine a target gear ratio. The processor can instruct the CVT to change the gear ratio to the target gear ratio at a rate corresponding to the rate of change in the acceleration input device.07-28-2011
