Abstract
A gear shift control apparatus for a hybrid vehicle 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.
