Abstract
A weight ratio of each driving wheel of the vehicle at the time of automatic driving is calculated, a front and rear distribution ratio of a driving force of the vehicle is calculated from the weight ratio, a rear wheel plan driving force is calculated from the front and rear distribution ratio and an action plan required driving force, and a temperature of a rear wheel motor is estimated. Then, when the estimated attainment temperature of the rear wheel motor is higher than the upper limit value of the temperature, the front and rear distribution ratio is changed within a range in which excessive slip does not occur at the front wheels, the rear wheel plan driving force is recalculated, and the automatic driving of the vehicle is implemented taking the rear wheel plan driving force as a target driving force.
