초록

A hybrid vehicle is disclosed, in which the drive torque is controlled according to a target, and the engine operating point and the battery charging rate are controlled thereby as targeted to improve the fuel consumption rate of the hybrid vehicle as a whole. An engine torque estimating unit 41 estimates the engine torque based on the motor current, and an engine output correction unit 42 calculates a correct value of the throttle opening based on the difference between the estimated value and the target value. The battery management unit 43, on the oth...
