For the first time ever a hybrid system using a 42V power supply system has been developed for better fuel economy, lower emission and urban environment. This paper introduces ths system configuration, features and gives actual vehicle evaluation results and future technical issues. The system has a motor generator connected to the engine crankshaft via a belt, in place of the alternator on a conventional vehicle. The electronic control of the motor generator has five functions: restarting the stopped engine, driving the vehicle when starting, driving auxiliaries when the englne is stopped, power generation during ordinary traveling and regenerative braking on deceleration braking, By restarting the engine via a belt with motor drive control, a smooth starting without discomfort is achieved. Furthermore, using this motor to drive auxiliaries during idle increases the number of idle stop opportunities. Installing this system on a direct injection 3,0 liter engine with a 5-speed automatic transmission improves fuel economy by about 40% in the Japanese standard urban mode, when compared to the average fuel consumption of vehicles in the same class without the system.
