Title:
VIBRATION NOISE CONTROLLER FOR VEHICLE
Document Type and Number:
Japanese Patent JP3348875
Kind Code:
B2
Abstract:
PURPOSE: To perform adaptive control with high precision by easily and speedily identifying transmission characteristics of a vibration noise path.
CONSTITUTION: A 1st residue signal η after a large-amplitude period signal is removed is generated with the canceling signal ρ and error signal ε of an E filter 31 identified according to the input signal (timing pulse signal) X' from an engine and then inputted to a transmission characteristic identifying means 29. In the transmission identifying means 29, the transmission characteristics of the vibration noise path are identified from a 2nd residue signal &phiv , a reference signal L', and the current filter coefficient of a C filter 34, the identified transmission characteristics are stored in a register part 30; and the filter coefficient of a W filter 25 is updated in consideration of the reference signal R outputted from the register part 30.
