Patent ID: 7381146

Claim:
A hybrid vehicle comprising an engine ( 1 ), a transmission ( 2 ) which changes a speed of a rotation of an input shaft and transmits the rotation to an output shaft, a motor generator ( 4 ), a power transmission mechanism ( 5 ) which connects a rotary shaft of the motor generator ( 4 ) and the input shaft of the transmission ( 2 ), a storage device ( 9 ) which is connected to the motor generator ( 4 ), and a controller ( 10 ), characterized in that the controller ( 10 ) sets an engine torque at a point on an engine torque high efficiency line at a current engine rotation speed as a target engine torque, calculates a current engine torque from the current engine rotation speed and a current accelerator depression amount, and when a gear position of the transmission ( 2 ) is neutral, the vehicle is stationary, and the storage device ( 9 ) requires charging, sets a difference between the target engine torque and the current engine torque as a target power generation torque of the motor generator ( 4 ), and controls the motor generator ( 4 ) such that a power generation torque of the motor generator ( 4 ) matches the target power generation torque.
