Patent ID: 8849527

Claim:
A method of regulating speed of a machine including a continuously variable transmission (CVT) operatively coupled to a power source; the method comprising: selecting a first virtual gear ratio from a plurality of virtual gear ratios associated with the CVT; receiving an operator input signal commanding a CVT output speed associated with the first virtual gear ratio; locking a power source speed between a minimum power source limit and a maximum power source limit related to the first virtual gear ratio; shifting from the first virtual gear ratio to a second virtual gear ratio to change the CVT output speed; comparing the power source speed to the minimum power source limit and the maximum power source limit related to the second virtual gear ratio; and responsively limiting the power source speed if outside the minimum power source limit or the maximum power source limit related to the second virtual gear ratio to fall between the minimum power source limit and maximum power source limit associated with the second virtual gear ratio.
