CVT Control System Discrete Speed Ranges

The continuous speed range of the CVT is segmented into multiple discrete selectable speed ranges (e.g., first speed range, second speed range, third speed range) with different maximum speeds. This allows the operator to select appropriate speed ranges for different working conditions, providing familiar discrete control while maintaining CVT's continuous variability within each range, thus resolving the contradiction between engine efficiency and operator control ease.

The system dynamically adapts the accelerator pedal's function based on the selected speed range. When a speed range is selected, the pedal controls speed within that range rather than always commanding maximum speed. This dynamic adjustment allows operators to easily maintain intermediate speeds by simply selecting the appropriate range and using normal pedal input, eliminating the fatigue caused by constantly modulating pedal position for rough terrain.

The patent merges the advantages of conventional discrete gear transmissions with the advantages of CVT technology. The system combines the discrete speed range selection (providing familiar gear-like control) with continuous variable transmission (providing smooth acceleration and engine efficiency). This hybrid approach gives operators the familiarity of discrete gears while eliminating the complexity and mechanical limitations of multi-gear transmissions.
