A driving force control system for an automotive vehicle provided with a transmission including a first motor-generator connected to an engine, and a second motor-generator connected to road wheels and driven by electric power generated by the first motor-generator. A first rotational speed sensor is provided for detecting a rotational speed of the first motor-generator. A second rotational speed sensor is provided for detecting a rotational speed of the second motor-generator. A control unit is provided programmed to control the rotational speed of the first motor-generator in accordance with the rotational speed of the second motor-generator. Additionally, the control unit is programmed to control a ratio between a first driving frequency for the first motor-generator and a second driving frequency for the second motor-generator so as to control the rotational speeds of the first and second motor-generators.
