ABSTRACT:
A control system for a rotary transmission for controlling pressure during speed ratio changes. The system includes a pump for delivering fluid under pressure which fluid selectively engages speed ratio selectors to enable the drive to be transmitted through the transmission. The system also embodies a regulator for regulating the fluid pressure in response to a throttle controlled torque demand signal. The system also includes sensors arranged to provide a signal to indicate the state of a speed ratio as well as a command signal to effect a change in the speed ratio.
