A vehicle driving force control device including an input shaft rotation number sensor which detects a transmission input shaft rotation number to be input from an engine to an automatic transmission, an accelerator opening sensor which detects accelerator opening, a TCU for calculating a required output of the automatic transmission based on the transmission input shaft rotation number and the accelerator opening, and an electronic control unit which controls the engine and the automatic transmission based on the required output. The TCU sets the required output to a constant value regardless of the transmission input shaft rotation number when the accelerator opening is not larger than a predetermined value, and sets to increase or decrease the required output according to increase and decrease of the transmission input shaft rotation number when the accelerator opening is larger than the predetermined value.
