Abstract

This clutch control device includes an engine (13), a transmission (21), a clutch device (26) configured to connect and disconnect motive power transmission between the engine (13) and the transmission (21), a clutch actuator (50) configured to drive the clutch device (26) and change a clutch capacity, a clutch operating element (4b) configured to enable the clutch device (26) to be manually operated, and a control unit (60) configured to calculate a target value (Pt) of a control parameter (Ps) of the clutch capacity in accordance with an amount of operation on the clutch operating element (4b). When the clutch device (26) is operated on a connection side according to an operation on the clutch operating element (4b), the control unit (60) is configured to set the target value (Pt) to a quick connection target value (Pmax) obtained by making a change to the connection side of the clutch device (26) with respect to an operation correspondence target value (Pv) according to the amount of operation on the clutch operating element (4b) if a speed of the operation on the clutch operating element (4b) is higher than or equal to a predetermined specified speed (Sp1).

First claim

What is claim is:

1. A clutch control device comprising:
an engine;
a transmission;
a clutch device configured to connect and disconnect motive power transmission between the engine and the transmission;
a clutch actuator configured to drive the clutch device and change a clutch capacity;
a clutch operating element configured to enable the clutch device to be manually operated; and
a control unit configured to calculate a target value of a control parameter of the clutch capacity in accordance with an amount of operation on the clutch operating element,
wherein, the clutch device operates on a connection side configured to connect motive power between the engine and the transmission and a disconnection side where no motive power is connected between the engine and the transmission, and when the clutch device is operated on the connection side according to an operation on the clutch operating element, the control unit is configured to set the target value to a quick connection target value obtained by making a change to the connection side of the clutch device with respect to an operation correspondence target value according to the amount of operation on the clutch operating element when a speed of the operation on the clutch operating element is higher than or equal to a predetermined specified speed.

2. The clutch control device according to claim 1 , wherein a quick clutch connection mode in which the target value is set to the quick connection target value continues for a predetermined specified time period.

3. The clutch control device according to claim 2 , wherein the specified time period changes with the speed of the operation on the clutch operating element.

4. The clutch control device according to claim 2 , wherein the quick clutch connection mode is released when the specified time period has elapsed.

5. The clutch control device according to claim 1 , wherein, when a rotational speed of the engine is higher than or equal to a predetermined specified rotational speed, the target value is set to the quick connection target value.

6. The clutch control device according to claim 1 , wherein the quick connection target value is the target value when the clutch actuator is driven at an upper limit.
