The driving force control apparatus of the vehicle controls the speed ratio in accordance with the transmission line set on the low speed side in the practical area, rather than the optimum fuel consumption line obtained based on the efficiency of the engine and the transmission. As a result, the speed of rotation increase from the start of the utility zone is suppressed. Therefore, fuel consumption of the inertia torque accompanying the rotational fluctuations of the engine, that is, the rotational fluctuations of the fluid power transmission mechanism and the input shaft of the transmission, is suppressed, and the efficiency as a whole is improved than in the case of the optimum fuel consumption line, and the fuel economy is improved. |
