Abstract
A gear shift control apparatus for a hybrid vehicle is disclosed which can achieve enhancement of the transmission efficiency and enhancement of the fuel cost without damaging the drivability to the utmost. The gear shift control apparatus for a hybrid vehicle includes an engine, a transmission for changing the speed of rotation of the engine, and a motor for assisting the driving force of the engine. The assist torque maximum value of the motor is set higher when the gear position of the transmission is a predetermined gear position at which the transmission efficiency of the driving force is highest than when the gear position is any other gear position than the predetermined gear position.
