1. A vehicle integrated-control device that integrally controls a plurality of actuators mounted in a vehicle to control the vehicle using six control axes which are front-rear, left-right, up-down, roll, pitch, and yaw control axes, the vehicle integrated-control device comprising:
a command value acquisition unit that acquires an external command corresponding to each of at least one and not more than six control axes for realizing a desired driving operation;
a command value supplementation unit that generates an internal command for a control axis, among the six control axes, for which no external commands were input to the command value acquisition unit; and
an operation amount control distribution unit that controls the plurality of actuators based on the external command and the internal command;
wherein the internal command is a command for controlling the plurality of actuators so as to improve a sensitivity index relating to an occupant of the vehicle;
wherein the command value supplementation unit corrects the external command based on an allowable fluctuation range that is set for each of the external commands;
and wherein, in a case where commands pertaining to the front-rear control axis and the left-right or yaw control axis are inputted as the external commands,
the command value supplementation unit corrects an external command pertaining to the front-rear control axis by adding or subtracting an amount proportional to a time change in left-right acceleration and not exceeding the allowable fluctuation range that is set for the external command pertaining to the front-rear control axis.
