Title:
CLUTCH CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/065248
Kind Code:
A1
Abstract:
One problem the present invention addresses is providing a clutch control device capable of achieving both inhibition of vibrations occurring in a vehicle and shortening of the time for changing the state of clutch engagement. As a solution for the problem, the present invention is a clutch control device (1) for changing the transmission state of a clutch unit (20) by controlling the action of an electric oil pump (10), wherein the clutch control device is provided with: a pressure control valve (60) that is disposed between an oil passage (Pa), which connects the electric oil pump (10) and the clutch unit (20), and an oil pan (90) in which unpressurized hydraulic oil is stored, and that discharges pressurized hydraulic oil from the oil passage (Pa) to the oil pan (90) when the pressure of the hydraulic oil exceeds a valve-opening pressure; and a pump drive control unit (100) for controlling oil pressure by driving the electric oil pump (10) on the basis of a target pressure indicated in a command to change the clutch unit (20) transmission state and the oil pressure detected by a pressure detection unit (40).
