    Abstract: PROBLEM TO BE SOLVED: To improve the accuracy in correcting the transmission torque of a clutch when the clutch is slipping.SOLUTION: Correction of AT transmission torque Tat deviating from an instruction value by using a difference ΔTat between an estimation value of the AT transmission torque Tat and the instruction value thereof makes it possible to improve accuracy in correcting the AT transmission torque Tat in an inertia phase of speed change transition of a transmission 20. That is, the difference between the instruction value of the AT transmission torque Tat and the estimation value thereof is directly corrected, and therefore it is possible to correct the AT transmission torque Tat as required. Here, using of differences ΔTat at plural temporal points in the inertia phase instead of one point therein enables correction even if there is a variation trend of the difference ΔTat throughout an inertia phase. That is, for magnification of the difference ΔTat, and variations thereof in any temporal point throughout the inertia phase, it is possible to acquire plural times of learning opportunities with only one execution of speed change. This enables improvement in accuracy of a learning value ΔTgk and in converging performance.

    Abstract: PROBLEM TO BE SOLVED: To improve the accuracy in correcting the transmission torque of a clutch when the clutch is slipping.SOLUTION: Correction of AT transmission torque Tat deviating from an instruction value by using a difference ΔTat between an estimation value of the AT transmission torque Tat and the instruction value thereof makes it possible to improve accuracy in correcting the AT transmission torque Tat when a transmission 20 is engaged in changing speeds. That is, the difference between the instruction value of the AT transmission torque Tat and the estimation value thereof is directly corrected, and therefore it is possible to correct the AT transmission torque Tat as required. Here, using of a delay-considered instruction value for the instruction value of the AT transmission torque Tat makes it possible to reduce a temporal error between the instruction value and estimation value at the time of calculating the difference ΔTat, enabling a further accuracy in correcting the AT transmission torque Tat. This enables improvement of a life of components (e.g., a friction member of a clutch C) and suppression of deterioration in drivability.
