1. A vehicle integrated control device that controls a motion parameter of a vehicle in which a plurality of actuators are installed, which are configured by a direction of movement on up to three control axes and the direction of rotation around the control axes, the device comprising:
a first target value generation unit that acquires a target momentum of a control axis related to a driving task of the vehicle and generates a first motion parameter that is at least one motion parameter;
a second target value generation unit that generates a second motion parameter different from the first motion parameter based on the first motion parameter to optimize a sensitivity index;
a limit generation unit that generates a motion limit amount of the second motion parameter based on the first motion parameter and an operation range of an actuator;
a final target generation unit that corrects the second motion parameter based on the motion limit amount; and
an operation amount assignment unit that generates an operation amount of an actuator based on the first motion parameter and the second motion parameter corrected by the final target generation unit.
