ABSTRACT:
A CVT is operated in both a continuously-variable mode and in a simulated stepped-ratio mode. In the stepped ratio mode, the highest preset transmission ratio (e.g., "first gear"), is variable and responsive to vehicle driving conditions. A control senses a low vehicle speed operating condition and adapts the highest ratio to reduce the step up to the next preset ratio. The control also senses a vehicle start condition and adapts the highest ratio to the current engine torque to improve drivability.
