Problems solved by technology

However, since the state of the vehicle changes when the brakes are only applied to the driving wheels or due to changes in road conditions other than the engine brake, the mechanism estimated from parameters indicating the operating state may not be able to accurately determine the grip state of the tires.

Embodiment Construction

[0028] Hereinafter, a clutch control system for a straddle type vehicle according to the present invention will be described with reference to FIGS. 1 to 7 while giving embodiments. The clutch control system 10 of this embodiment is mounted on a motorcycle 11 . First, the motorcycle 11 will be described.

[0029] In this embodiment, as shown in FIG. 1 , a full cowling type (full cowling type) automatic two-wheeled vehicle (straddle type vehicle) 11 is illustrated for description, but the present invention is not limited thereto, and can also be applied to Other types of straddle-type vehicles (eg, scooters, buggy). In addition, in this motorcycle 11 , for the mechanisms and components provided symmetrically on the left and right sides of the vehicle body, "L" is attached to the reference sign on the left side, and "R" is attached to the reference sign on the right side. In addition, in the following description, "right" means the right side of the vehicle body seen from the ...

Abstract

The invention provides a clutch control system maintaining a grip force of a driving wheel by identifying an actual condition of a motorcycle and controlling a clutch in a timely manner. The clutch control system (10) of the saddle-ride type vehicle includes: a clutch (44) connecting and disconnecting a driving force from an engine (40) relative to a rear wheel (16); an actuator unit (45) causing the clutch (44) to engage or disengage using a clutch lever (46) or automatically; a rear wheel speed sensor (56); a front wheel speed sensor (58); a clutch lever sensor (48); and a controller (47) controlling a control motor (110) based on a rear wheel speed (Pr) and a front wheel speed (Pf). When the rear wheel speed is lower than the front wheel speed and an absolute value of a difference between the rear wheel speed and the front wheel speed is greater than a threshold value (P1), the control motor is driven so as to reduce a transmission force of the clutch. When an operation amount (C) of the clutch lever is greater than a threshold value (C1), processing to reduce the transmission force of the clutch is suspended.

Description

technical field [0001] The present invention relates to a clutch control system for a saddled vehicle including a clutch for disconnecting driving force from an engine to drive wheels, an actuator for disconnecting the clutch, and an actuator control mechanism for controlling the actuator. Background technique [0002] In a general motorcycle, the output of the engine is transmitted to the driving wheels through the clutch. In an automatic two-wheeler, the engine brake is activated when performing a sharp downshift, and the grip from the road surface is reduced. In addition, the grip of the tires may decrease, and the driving wheels may become idling. In order to cope with the situation caused by such an engine brake, a technique of performing clutch disengagement control (for example, Patent Document 1) or providing a back torque limiter has been proposed. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2003-294062 [0004] In the aforementioned Patent Document...
