A METHOD OF MAKING A SYNCHRONOUS SHIFT BETWEEN TWO MODES OF A MULTI-MODE CONTINUOUSLY VARIABLE TRANSMISSION USING A BALL VARIATOR AND A DOG-STYLE CLUTCH OR SYNCHRONIZER

摘要

An electronic controller is described herein that enables electronic control over a variable ratio transmission comprising a continuously variable ratio portion, such as a Continuously Variable Transmission (CVT), Infinitely Variable Transmission (IVT), or variator. The electronic controller is configured to receive input signals indicative of parameters associated with a prime mover or an engine coupled to the transmission. The parameters include throttle position sensor values, vehicle speed, gear selector position, user selectable mode configurations, and the like, or some combination thereof. The electronic controller also receives one or more control inputs. The electronic controller determines an active range and an active variator mode based on the input signals and control inputs. The electronic controller controls a final drive ratio of the variable ratio transmission by controlling one or more electronic actuators and/or solenoids that control the ratios of one or more portions of the variable ratio transmission.
