SYSTEM FOR REDUCING TORSIONAL VIBRATION OF A DRIVING SYSTEM FOR A VEHICLE, CAPABLE OF REDUCING THE TORSIONAL VIBRATION OF THE DRIVING SYSTEM WITHOUT INFLUENCING TO ENGINE PERFORMANCE

摘要

PURPOSE: A system for reducing torsional vibration of a driving system for a vehicle is provided to recognize a torsional resonance band and to enable the driving system to perceive ignition timing of an engine without changing the ignition timing of the engine in whole driving section of the engine.;CONSTITUTION: A system for reducing torsional vibration of a driving system for a vehicle comprises: a sensor unit which senses a torsional resonance band of the driving system; and a controller(60) controlling the driving system to perceive ignition timing of an engine based on information of the sensor unit when driving system is within the torsional resonance band. The sensor unit comprises an engine speed sensitive unit(10), a transmission speed sensitive unit(20), a driving system speed sensitive unit(30), and an engine torque sensitive unit(40).;COPYRIGHT KIPO 2010
