A driving force control device for a vehicle is provided, which includes a motor, an engine, and a controller. The controller sets a target torque of the vehicle corresponding to accelerator operation, distributes a target engine torque, based on the target torque, and outputs a control signal corresponding to the target engine torque. The controller estimates a future amount of intake air to a cylinder based on the target engine torque, and estimates an engine torque after a setup time from the present time based on the estimated future amount of intake air. The controller sets a target motor torque after the setup time based on the estimated engine torque after the setup time so that the target torque is achieved, and outputs a control signal corresponding to the target motor torque to synchronize a torque response of the engine with a torque response of the motor.
