Abstract

Official abstract text for this publication.

This clutch control device includes a clutch device configured to connect or disconnect power transmission between a prime mover and an output target, a clutch actuator configured to output a drive force for actuating the clutch device, and a control unit configured to control driving of the clutch actuator, in which the clutch actuator includes a plurality of drive sources that output the drive force.

First claim

Opening claim text (preview).

What is claim is: 1. A clutch control device comprising: a clutch device configured to connect or disconnect power transmission between a prime mover and an output target; a clutch actuator configured to output a drive force for actuating the clutch device; and a control unit configured to control driving of the clutch actuator, wherein the clutch actuator includes a plurality of drive sources that output the drive force, and when one of the plurality of drive sources becomes undrivable, the clutch device is once disconnected by the other of the plurality of drive sources, and then is gradually connected thereafter. 2. The clutch control device according to claim 1 , wherein the control unit feedback-controls a current supplied to each of the plurality of drive sources. 3. The clutch control device according to claim 1 , wherein the control unit includes a plurality of drive control means independent from each other, and each of the plurality of drive sources is independently controllable by any one of the plurality of drive control means. 4. The clutch control device according to claim 1 , wherein, when one of the plurality of drive sources becomes undrivable, a drive current for driving the other of the plurality of drive sources is set larger than that for normal drive, and only one cycle of clutch disconnection and connection is performed. 5. The clutch control device according to claim 1 , wherein a fail-safe relay is included in a current supply line of the plurality of drive sources, and the clutch device is gradually connected by intermittently driving the fail-safe relay when a failure has occurred in one of the plurality of drive sources. 6. The clutch control device according to claim 5 , wherein the control unit includes a plurality of drive control means independent from each other, and the fail-safe relay is configured to be controllable by a second control means different from a first drive control means that controls the plurality of drive sources during a normal operation.
