STEERING ASSIST RATIO COMPUTATION DEVICE OF POWER STEERING SYSTEM AND METHOD OF COMPUTING STEERING ASSIST RATIO OF POWER STEERING SYSTEM

摘要

PROBLEM TO BE SOLVED: To set an optimum assist ratio of steering and thereby improve the steering feeling of a driver.;SOLUTION: An assist ratio computation device 100 of a power steering system according to the present invention comprises: a driving state acquisition unit 126 for acquiring a driving state that corresponds to a driving route on the basis of information pertaining to the current location of a vehicle and a destination place; and an assist ratio acquisition unit 127 for acquiring an assist ratio that corresponds to the acquired driving state that corresponds to the driving route from a database 150 in which an assist ratio is defined for each driving state where the discrete degree of biological information associated with steering decreases.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
