Infinitely variable transmission with controlled coasting

摘要

A system for driving a machine is provided. A user input device inputs a desired throttle setting for the machine. The system includes an infinitely variable transmission having a transmission ratio that is adjustable. At least one sensor determines an inclination of the machine relative to a reference plane. A controller is configured to determine and apply a variable rate limit upon change in the transmission ratio based on the inclination of the machine when the desired throttle setting is reduced more than a predetermined amount and to adjust the rate limit based on the difference between an actual engine speed and a desired engine speed.

1. A system for driving a machine comprising:
a user input device for inputting a desired throttle setting for the machine; an infinitely variable transmission having a transmission ratio that is adjustable; at least one sensor configured to determine an inclination of the machine relative to a reference plane; and a controller in communication with the user input device to receive information relating to the desired throttle setting and the sensor to receive information relating to the inclination of the machine; the controller being in communication with the infinitely variable transmission and configured to control the transmission ratio, the controller being configured to determine and apply a variable rate limit upon change in the transmission ratio based on the inclination of the machine when the desired throttle setting is reduced more than a predetermined amount.
