CLUTCH CONTROL SYSTEM FOR VEHICLE

A clutch control system for vehicle is applied to a vehicle (1) having a clutch (3) and a transmission (4) disposed in a power transmission path (6) from an engine (2) to a vehicle wheel (5). The system includes a first rotational speed detecting unit (28) to detect a driving side rotational speed of the clutch (3), a second rotational speed detecting unit (16, 50) to detect a driven side rotational speed of the clutch (3), a half-clutch control unit (10, S5, S33, S34, S44, S45, S53 to S55), and a half-clutch transition control unit (10, S4, S11 to S13). The half-clutch control unit (10, S5, S33, S34, S44, S45, S53 to S55) executes a first half-clutch control on the clutch actuator (11) when a gear position of the transmission (4) and a rotational direction of a driven side portion (32) of the clutch (3) are matched and executes, on the clutch actuator (11), a second half-clutch control, differing from the first half-clutch control, when the gear position of the transmission (4) and the rotational direction of the driven side portion (32) of the clutch (3) are not matched.
