<P>PROBLEM TO BE SOLVED: To provide a driving torque control device of a hybrid vehicle suitable for improving in gear backlash reducing accuracy. <P>SOLUTION: The driving torque control device includes a transmission input torque limiting means which restricts the input torque to a transmission 3 to a prescribed value (gear backlash reducing torque) which is smaller than the target drive torque and larger than zero torque, when the target drive torque set according to the gas pedal operation and the vehicle speed changes to a positive torque from a negative torque, while determining the gear backlash reducing until the transmission driving system from the transmission 3 to the driving wheel 2 changes from a negative driving state to a positive driving state. Then the transmission input torque limiting means, in a hybrid travel mode, makes the requesting torque to the engine 1 held in a larger value out of the engine torque command value when the target drive torque changes from the negative torque to the positive torque and the engine combustion lower limit torque, and corrects the difference with the prescribed value (gear backash stuffing torque) by a motor generator 5. <P>COPYRIGHT: (C)2012,JPO&INPIT |
