Controller for a continuously variable transmission
First Claim
1. A clamp pressure controller for controlling the clamp pressure applied to a belt of a continuously variable transmission, which transmission is in combination with a generator, the controller having a fast response mode such that in response to an input indicative of an event that may result in an increase in mechanical load transmitted through the continuously variable transmission, the controller initiates an increase in the clamp pressure in order to protect the continuously variable transmission against belt slippage.

Abstract
A clamp pressure controller for a variable ratio belt drive system for a generator is provided. The controller monitors the voltage at the output of the generator. If this falls the controller increases the clamp pressure so as to prepare the drive system for the additional torque/force it will be required to transmit. The increase in clamp pressure is rapid so as to prevent belt slip from occurring.
