PROBLEM TO BE SOLVED: To further improve performance concerning traveling efficiency, fuel consumption, etc., by controlling the distribution of driving force for front and rear wheels, based on an accumulation quantity of an accumulation device. SOLUTION: Switching patterns A, B and C set accelerator manipulated variable θ AC and car velocity V as parameter, the switching pattern B is the basic pattern set so as to travel with the minimum fuel consumption, a traveling area having required output smaller than engine output is set with RR mode, and the traveling area having required output larger than engine output is set with 4WD1 mode. The switching pattern A in the case of an overcharge state is set with FF2 mode and 4WD2 mode so as to consume more electric energy of the accumulation device, and the switching pattern C in the case of a discharge state is set with the RR mode and 4WD1 mode for controlling the consumption of electric energy. As a result, since the distribution of driving force for front and rear wheels is controlled on the basis of an accumulation quantity of the accumulation device, traveling efficiency, fuel consumption, etc., can be further improved. |
