Abstract

A grip force of a driving wheel is maintained by identifying an actual condition of a motorcycle and controlling a clutch in a timely manner. A clutch control system includes a clutch, an actuator unit causing the clutch to engage or disengage, a rear wheel speed sensor, a front wheel speed sensor, a clutch lever sensor and a controller controlling a control motor based on a rear wheel speed and a front wheel speed. 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, the control motor is driven so as to reduce a transmission force of the clutch. When an operational amount of the clutch lever is greater than a threshold value, processing to reduce the transmission force of the clutch is suspended.
