Abstract:
A drive system for a vehicle, comprising:an engine, a generator connected to the engine, which regenerates the output of the engine, a motor for driving the vehicle which operates by power supplied from the generator, a battery which supplies power to the motor when the power supply to the motor is insufficient, and stores excess power when the supplied power is excessive, a sensor which detects a vehicle running state, and a controller which functions to: when the engine and generator are controlled so that the power generated by the generator is different from the power consumption of the motor, compute a virtual generated power, which is the power generated by the generator when the engine and generator are controlled so that the power generated by the generator coincides with the power consumption of the motor which is uniquely determined according to the vehicle running state, compute an output limiting value of the motor based on the virtual generated power, and limit the power or torque of the motor by the output limiting value.
