<P>PROBLEM TO BE SOLVED: To provide a drive device for hybrid vehicle that can reduce the gear shift shock while eliminating the free running feeling at the gear shift operation. <P>SOLUTION: A gear shift control device for the hybrid vehicle is assumed a drive device for a hybrid vehicle including an engine, an automatic transmission, a clutch, and a motor generator to be a control object, and includes: a means to direct a driver request torque Tdrv set by the operation amount of an accelerator means; a means to generate the motor torque while decreasing the engine torque TeX when the gear shift condition is met, to disengage the clutch, to return the clutch to a connected state after switching the gear train, and to increase the engine torque while decreasing the motor torque; and a means to obtain the motor torque Tm1 by subtracting the clutch torque Tc from the driver request torque while the rotation speed difference ΔN obtained by subtracting the transmission input rotation speed Ni from the engine rotation speed Ne after switching the gear train to enlarge the gear ratio, exceeding the first prescribed value N1. <P>COPYRIGHT: (C)2013,JPO&INPIT |
