Abstract:
A drive power control device for a hybrid vehicle running by the drive power of at least one of an engine and a motor comprising:an accelerator sensor detecting a depression amount of an accelerator pedal;a vehicle speed sensor detecting a vehicle speed;a battery performing storage and output of electrical force with said motor;a battery sensor detecting the state of charge of said battery; anda controller controlling said engine and said motor, said controllercalculating a target drive torque based on said vehicle speed detection value and said accelerator pedal depression amount value,calculating a generator torque of said motor based on said state of charge detected value,controlling said engine to a torque value to obtain said target drive torque and said generator torque as a target engine torque,estimating an actual torque of said engine, andcontrolling said motor to a difference of said target drive torque and said engine torque estimated value as a target motor torque.
