A driving force control device includes an individual-wheel friction-circle limit-value calculating portion that calculates friction-circle limit-values of individual wheels, an individual-wheel requested-resultant-tire-force calculating portion that calculates requested resultant tire forces of the individual wheels, an individual-wheel resultant-tire-force calculating portion that calculates resultant tire forces of the individual wheels, an individual-wheel requested-excessive-tire-force calculating portion that calculates requested excessive tire forces of the individual wheels, an individual-wheel excessive-tire-force calculating portion that calculates excessive tire forces of the individual wheels, an excessive-tire-force calculating portion that calculates an excessive tire force, an over-torque calculating portion that calculates an over-torque, and a control-amount calculating portion that calculates a control amount that is output to an engine control unit.

In a throttle valve control device, an engine required output setting section sets an engine required output corresponding to an accelerator opening degree by means of selecting a characteristic which is varied depending on a road surface friction coefficient or by means of interpolation calculation based on a road surface friction coefficient. An engine required torque setting section sets an engine required torque based on an engine speed and the engine required output. A throttle opening degree setting section sets a throttle opening degree based on the engine speed and the engine required torque and outputs a signal corresponding to the throttle opening degree to a throttle motor.

An adjustment unit identifies a front-rear driving force distribution control unit and a braking force control unit, and calculates based on the current vehicle state, a target yaw moment required for each of the front-rear driving force distribution control unit and braking force control unit. Then, based on the current operating state of each of the control units, a control correction value for each unit is calculated in consideration of the maximum value, and outputted.
