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