Summary:To maintain a grip force of a driving wheel by identifying an actual condition of a motorcycle (11) and controlling a clutch (44) in a timely manner. A clutch control system (10) 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 (Pr) is lower than the front wheel speed (Pf) and an absolute value of a difference between the rear wheel speed (Pr) and the front wheel speed (Pf) is greater than a threshold value (P1), the control motor (110) is driven so as to reduce a transmission force of the clutch (44). When an operation amount (C) of the clutch lever (46) is greater than a threshold value C1, processing to reduce the transmission force of the clutch (44) is suspended.
