Abstract

A clutch control device includes an engine, a gearbox, a clutch device configured to disconnect and connect power transmission between the engine and the gearbox, a clutch actuator configured to drive the clutch device and vary a clutch capacity, an engine rotational number sensor configured to detect an engine rotational number, a throttle opening angle sensor configured to detect a throttle opening angle, and a controller configured to calculate a control target value of the clutch capacity, wherein the controller calculates an estimated engine torque and causes the clutch device to change a slip clutch capacity according to the estimated engine torque.

First claim

What is claimed is:

1. A clutch control device comprising:
an engine;
a gearbox;
a clutch device configured to disconnect and connect power transmission between the engine and the gearbox;
a clutch actuator configured to drive the clutch device and vary a clutch capacity;
an engine rotational number sensor configured to detect an engine rotational number;
a throttle opening angle sensor configured to detect a throttle opening angle;
a controller configured to calculate a control target value of the clutch capacity; and
a bank angle sensor configured to detect a bank angle,
wherein the controller calculates an estimated engine torque and causes the clutch device to change a slip clutch capacity according to the estimated engine torque, and
wherein the controller outputs the control target value that differs according to the bank angle.

2. The clutch control device according to claim 1 ,
wherein the controller sets the clutch capacity according to a state of a vehicle as the control target value when the estimated engine torque is less than a predetermined value.

3. The clutch control device according to claim 1 ,
wherein the controller sets the clutch capacity according to a state of a vehicle as the control target value when a clutch differential rotational number, which is a rotational number difference between upstream rotation and downstream rotation of the clutch device, exceeds a predetermined value.

4. The clutch control device according to claim 1 ,
wherein the controller calculates a clutch differential rotational number which is a rotational number difference between upstream rotation and downstream rotation of the clutch device, and outputs the control target value that differs according to the clutch differential rotational number.

5. The clutch control device according to claim 4 , further comprising: a storage that stores a control target value map in which the control target value that differs according to the clutch differential rotational number is set,
wherein the controller outputs the control target value on the basis of the clutch differential rotational number and the control target value map.

6. The clutch control device according to claim 1 , further comprising a gear position sensor configured to detect a gear position,
wherein the controller outputs the control target value that differs according to the gear position.

7. The clutch control device according to claim 6 , further comprising a storage that stores a control target value map in which the control target value that differs according to the gear position is set,
wherein the controller outputs the control target value on the basis of the gear position and the control target value map.

8. The clutch control device according to claim 1 , further comprising a storage that stores a control target value map in which the control target value that differs according to the bank angle is set,
wherein the controller outputs the control target value on the basis of the bank angle and the control target value map.

9. A clutch control system comprising:
the clutch control device according to claim 1 ; and
a clutch operator configured to manually operate the clutch device,
the clutch control system being switchable between to generate the clutch capacity according to an operation amount of the clutch operator and to designate a clutch capacity by using the controller,
wherein, when an engine torque and a clutch differential rotational number, which is a rotational number difference between upstream rotation and downstream rotation of the clutch device, satisfy a predetermined condition, in a case in which a clutch capacity according to the operation amount exceeds a predetermined value, the clutch capacity designated by the controller is output.
