METHOD AND APPARATUS FOR CALCULATING TORQUE CAPAITY OF CLUTCH OF VEHICLE

摘要

The present invention discloses a method and apparatus for calculating clutch torque capacity for vehicles. According to the present invention, when it is determined that the vehicle behavior is stabilized based on the change amount of the acceleration signal, the input torque change amount of the clutch, the vehicle speed change amount, and the absolute value of the clutch input torque, the clutch is slightly slip controlled, The clutch pressure and the clutch input torque ratio are derived as the torque capacity when the slip accumulation value with respect to the amount of slip is equal to or greater than a predetermined determination reference value and the integrated value of the calculated slip accumulation value is equal to or greater than the threshold value, The torque capacity that is varied due to the change of the characteristics of the clutch is accurately derived, and the precision oil pressure control of the clutch becomes possible.
