ON-LINE VIBRATION FREQUENCY ANALYSIS FOR RESOURCES UTILIZING SYSTEM

摘要

PROBLEM TO BE SOLVED: To improve performance of a vehicle by estimating an operation signal of the vehicle.;SOLUTION: The whole vibration frequency spectrum is obtained by sample- extracting a vehicle operation signal from a sensor arranged in a vehicle which signal corresponds to the state of a road. To a specified vibration frequency out of the spectrum, a weighting filter matrix is calculated and stored, thereby confirming vibration relating to the vibration frequency. The data are used for correction and improvement of vehicle control system.;COPYRIGHT: (C)2003,JPO
