  • Publication number: 20230313872
    Abstract: Aspects of the present disclosure relate to a powertrain assembly including a continuously variable transmission and, in some examples, a clutch. The clutch may be operably coupled between a prime mover and the continuously variable transmission. Additionally, or alternatively, a clutch may be operable coupled after or downstream of the continuously variable transmission. Aspects of the powertrain assembly may be controlled to provide starting-clutch functionality, to provide torque-limiting functionality, and/or to adapt operation of the powertrain for any of a variety of conditions.
