Vorrichtung und Verfahren zur Steuerung eines Automatikgetriebes von einem Kraftfahrzeug |
摘要 |
The invention comprises a detector (133) to detect the inertia phase at the time of shifting, a torque variation coefficient calculator (135) to calculate varying rate of the torque variation, a memory to store a constant value of the torque variation, a comparator (137) to compare the coefficient of the torque variation with the constant value, and command generator (138) to outputting commands for operating the transmission on the basis of the result of the comparison. Therefore, the torque fluctuations at the time of shifting decreases. <IMAGE> |
