Problems solved by technology

Therefore, it takes a long time to disengage the clutch, and the excessive rotation state of the internal combustion engine occurs, which may lower fuel efficiency or operating efficiency.
And, on the contrary, when the rotational speed of the internal combustion engine drops sharply and a shift operation is required, as described above, it takes a long time to disengage the clutch, so the rotational speed drops to an extremely low rotational speed region, and the operating state of the internal combustion engine may be unstable

Abstract

The invention provides a clutch device. When a plurality of clutches respectively connects / disconnects a plurality of power transmission paths, a prime mover can be prevented from rotating at an extremely high or extremely low speed, thereby ensuring high operation efficiency and excellent operation performance of the prime mover. The clutch device comprises clutches, clutch drive devices and AT / ECU. When one of the clutches is driven to a connected state through one of the clutch drive devices, the AT / ECU calculates estimated rotating speed NE_END (step 3) at the responding time when the piston of the other clutch drive device is driven to a releasing position and returns to an off position. When the estimated rotating speed NE_END is not within the preset rotating speed area (NE_L(NE_END(NE_H), driving the piston of the other clutch drive device at a releasing position is prohibited.

Description

technical field [0001] The present invention relates to a clutch device having a plurality of clutches connected / disconnected according to hydraulic pressure. Background technique [0002] Conventionally, a clutch device described in Patent Document 1 has been known. The clutch device is a clutch device for a vehicle, and includes a clutch provided between an engine and a transmission, a clutch drive device for switching the on / off state of the clutch, a control device for controlling the clutch drive device, and the like. The clutch is composed of a clutch disc, a pressure plate and a diaphragm spring. [0003] Moreover, the clutch driving device has an active hydraulic cylinder, a slave hydraulic cylinder connected with the active hydraulic cylinder through an oil circuit, an electric actuator for driving the active piston in the active hydraulic cylinder, etc., and the active hydraulic cylinder, the oil circuit and the slave hydraulic cylinder The dynamic hydraulic cyli...
