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 according to the present invention comprises: a driving state acquisition unit 126 for acquiring the current driving state of a vehicle; and an assist ratio acquisition unit 127 for acquiring an assist ratio that corresponds to the acquired current driving state from a database in which an assist ratio is defined for each driving state where the discrete degree of biological information associated with steering decreases. This construction allows the steering feeling of a driver to be improved by setting an optimum assist ratio of steering.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
