ROTATIONAL VIBRATION CONTROL DEVICE IN VEHICULAR DRIVING SYSTEM

摘要

PROBLEM TO BE SOLVED: To control rotational vibration efficiently even when the transmitting feature of the rotational vibration in a vehicular driving system is varied. SOLUTION: The controlling inputs to objects to be controlled are an engine torque command valve and a speed change ratio of continuously variable transmission 4. A vehicular state quantity detection unit 14 detects at least one of vehicle state quantities such as output shaft torque and the like as an observed quantity. Based on the observed result, a rotational vibration detection unit 16 detects the vibration component of the rotational vibration in a vehicular driving system. A rotational vibration control unit 22 in the vehicular driving system outputs either one or both of an engine torque changing quantity and a speed change ratio changing quantity for controlling the rotational vibration. And the unit feeds back these changing quantities to the engine torque and the speed change ratio output from an engine torque command unit 10 or a speed change ratio command unit 12.
