CLUTCH CONTROL DEVICE AND µ-CORRECTION FACTOR CALCULATING METHOD |
摘要 |
<p>Actual-rotational-difference absorption-torque calculation means (150) inputs a rate-of-change ”Ne of an engine speed during shifting to an actual rotational difference absorption torque-”Ne table (160) so that an actual-rotational-difference absorption-torque average value during shifting is calculated. Engine-torque calculation means (180) inputs a throttle opening and an engine speed to engine-torque estimation-value map (190), and derives an engine torque during shifting. An actual clutch capacity is calculated from the sum of the actual-rotational-difference absorption-torque average value and the engine torque average value during shifting. From the ratio of the actual clutch capacity and a demanded clutch capacity, µ-correction-coefficient calculation means (130) calculates a µ correction coefficient. By using a control correction amount calculated on the basis of the µ correction coefficient, a transmission control unit (100) drive-controls a first clutch (CL1) and a second clutch (CL2). Thus, correction on the clutch capacity is performed during running.</p> |
