View Patent ↗The present invention provides a system and method for automatically adjusting a continuously variable transmission (CVT) in a motorized vehicle. A microprocessor processor in the vehicle receives data about the operating status of the vehicle from a plurality. Examples of vehicle data include vehicle speed, motor speed, throttle position, current draw from a battery, and battery level. A servo motor is in mechanical communication with the CVT and provides an axial force to adjust the CVT. The microprocessor uses lookup tables of optimal set points for vehicle data to instruct the servo motor to adjust the transmission ratio of the CVT according to the vehicle data provided by the sensors.
