VEHICLE DRIVING POWER CONTROL METHOD AND DEVICE THEREFOR

Document Type and Number:

WIPO Patent Application WO/2018/084253

Kind Code:

A1

Abstract:

A driving power control device 1 for a vehicle V includes: a D-μ map M1 in which a linear correlation between driving stiffness D and a maximum road surface μ is set; a slip ratio calculation unit 21 for calculating a slip ratio S of front wheels 10L and 10R; a DS calculation unit 22 for calculating driving stiffness D corresponding to the slip ratio S calculated by the slip ratio calculation unit 21; a maximum road surface μ calculation unit 23 for calculating a maximum road surface μ by applying the driving stiffness D calculated by the DS calculation unit 22 to the D-μ map M1; and a driving power distribution unit 24 for controlling driving power by using the maximum road surface μ calculated by the maximum road surface μ calculation unit 23.
