ABSTRACT:
A starting clutch control device includes a starting clutch disposed between an engine and a transmission installed to a vehicle. A torque coefficient setting section sets a torque coefficient based on a clutch speed ratio of the starting clutch and a throttle opening of the engine. A torque coefficient correction section increases the torque coefficient by a torque coefficient correction amount, increasing the torque coefficient by a progressively larger torque coefficient correction amount as the throttle opening increases, in order to increase the torque coefficient within a region of smaller clutch speed ratios (e.g., clutch speed ratios less than approximately 0.5). A hydraulic pressure control section controls hydraulic pressure supplied to the starting clutch based on the torque coefficient and the rotational speed of the engine.
