Document Type and Number:
WIPO Patent Application WO/2015/143957
Kind Code:
A1
Abstract:
Disclosed are a hydraulic control mechanism, a clutch system and an automotive brake system, the hydraulic control mechanism comprising a master cylinder, a working cylinder, and a pedal; an automatic hydraulic drive device, comprising: an oil cylinder provided with a first and second oil port in communication with an inner cavity, the first and second oil ports being respectively connected to the master cylinder and the working cylinder via a hydraulic pipe; a first piston movably located within the inner cavity, there being a gap between the first and second oil ports in a moving direction of the first piston; a drive mechanism for driving the first piston to move within the inner cavity; and a control unit for controlling the drive mechanism to enable the first piston to keep in a position where the first and second oil ports are in communication with each other upon receiving a manual control command, and controlling the drive mechanism to drive the first piston to move to a position where the first and second oil ports are not in communication with each other upon receiving an automatic control command. The present invention solves the problems that the driver's labour intensity is increased due to the existing clutch and automotive brake control mechanism, and the clutch control mechanism functional safety is not high.
