<p><P>PROBLEM TO BE SOLVED: To realize control of a start clutch for a vehicle capable of preventing a reduction in starting response and a deterioration in durability of the start clutch while performing stable creep run in spite of running resistance of the vehicle. <P>SOLUTION: Creep clutch torque is set up in response to running resistance of the vehicle (step B31). A capacity coefficientτof the start clutch is calculated on the basis of a clutch speed ratio (the number of primary rotation of a continuously variable transmission/the number of rotation of an engine) (step B32), and a correction factor k is also calculated on the basis of the set-up creep clutch torque (or running resistance of the vehicle) (step B33). Then, start clutch torque is calculated by using the number of rotation Ne of the engine, the capacityτ, and the correction factor k (step B34), and target clutch torque of the start clutch is determined by performing selection of the maximum value among the set-up creep clutch torque and the calculated start clutch torque (step B35). <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
