초록

This invention describes a control method for a hydraulic coupling system that includes pressurizing a fluid in an actuator coupled to a multi-disk clutch pack to engage the clutch pack, pumping the fluid through the clutch pack to cool the clutch pack, and controlling one or more valve actuators and one or more pump-motors with a controller. The control method may incorporate pulse width modulation of the actuators, such as the actuators for the pump-motor and valve.

대표
청구항

What is claimed is: 1. A method of controlling a hydraulic coupling system, comprising pressurizing a fluid in an actuator coupled to a multi-disk clutch pack to engage the clutch pack; pumping the fluid through the clutch pack to cool the clutch pack; and transmitting pulse-width modulated control commands from a controller to a set of valves and at least one pump to control the operation of the set of valves and the at least one pump. 2. The method of claim 1 further comprising monitoring dynamics of a vehicle, the engagement of the clutch pack bei...
