Problems solved by technology

[0009] However, in the prior art described above, there is no mention of clutch disengagement performance (responsiveness) at the time of intervention of manual operation by the clutch control lever (during clutch disengagement operation).
[0010] That is, when the clutch capacity is controlled by hydraulic pressure, since friction (pressure loss) occurs in the hydraulic pressure path, the follow-up of the slave hydraulic pressure with respect to the target hydraulic pressure may be delayed, and the operation of the clutch may be delayed.
Especially during the disengagement operation of the clutch, if the hydraulic pressure of the controlled object is delayed with respect to the target hydraulic pressure, the driver will easily feel that the clutch is disengaged.

Embodiment Construction

[0042] Hereinafter, embodiments of the present invention will be described with reference to the drawings. It should be noted that directions such as front, rear, left, and right in the following description are the same as those in the vehicle described below, unless otherwise specified. In addition, an arrow FR indicating the front of the vehicle, an arrow LH indicating the left side of the vehicle, and an arrow UP indicating the upward direction of the vehicle are shown at appropriate places in the drawings used in the following description.

[0043]

[0044] like figure 1 As shown, this embodiment is applied to the motorcycle 1 which is a straddle-type vehicle. The front wheel 2 of the motorcycle 1 is supported by the lower end portions of a pair of left and right front forks 3 . Upper portions of the left and right front forks 3 are supported by a head pipe 6 at a front end portion of the body frame 5 via a steering rod 4 . On the top bridge of the steering rod 4, a ...

Abstract

The clutch control device includes an engine (13), a transmission (21), a clutch device (26), a clutch actuator (50), a control unit (60), a clutch operating member (4b), and a clutch operation amount sensor (4c). The control unit (60) can perform manual clutch operation based on the clutch operating member (4b) during the automatic control of the clutch device (26) based on the clutch actuator (50). When the control unit (60) performs the clutch disengagement operation based on the intervention of the manual clutch operation, the clutch operating member (4b) obtained based on the output value of the clutch operation amount sensor (4c) When the operation amount reaches a predetermined value (θ2) set in advance, the control target value of the clutch capacity is set relative to the relative operation target value corresponding to the operation amount of the clutch operating member (4b) ( Pv) The connection lower limit target value (Px) changed to the clutch disengagement side.

Description

technical field [0001] The present invention relates to clutch control devices. [0002] this application claims priority based on Japanese Patent Application No. 2017-210751 for which it applied in Japan on October 31, 2017, and uses the content here. Background technique [0003] Conventionally, in automatic clutch control by an actuator, intervention by manual operation of a clutch lever may sometimes be possible (for example, refer to Patent Document 1). [0004] In Patent Document 1, in order to smoothly perform manual operation intervention during automatic clutch control, in a state where the difference between the clutch capacity in automatic control and the calculated value of the manually operated clutch capacity is large, the manual operation clutch capacity is prevented from being transferred to the manual operation clutch capacity. The switching of the calculation value avoids the sudden change of the clutch capacity, so that the manual operation can be interve...
