Abstract
A method of managing a transmission ratio with an assisted CVT with a governed engine to emulate a hydrostatic transmission and prevent a drivebelt abuse is provided, the method comprising: providing a reference power source rotational speed, using the assisted CVT to transmit rotatable motion between a power source and a drive mechanism, managing a torque of the power source to maintain a substantially even rotational speed upon a power source load variation and modulating a transmission ratio of the assisted CVT to change the rotational speed of the drive mechanism. A system and a vehicle having such a drivebelt abuse preventing mechanism is also provided.
