Abstract

See full text

A driving force control device 1 for a vehicle V comprises: a D-μ map M1 defining a linear correlation between a driving stiffness D and a maximum road surface μ; a slip ratio calculation circuit 21 for calculating a slip ratio S of one of a pair of front road wheels 10L, 10R; a DS calculation circuit 22 for calculating the driving stiffness D corresponding to a value the slip ratio S calculated by the slip ratio calculation circuit 21; a maximum road surface μ calculation circuit 23 for assigning a value of the driving stiffness D calculated by the DS calculation circuit 22 to the D-μ map M1 to calculate the maximum road surface μ; and a driving force distribution circuit 24 for controlling a driving force, using a value of the maximum road surface μ calculated by the maximum road surface μ calculation circuit 23.
