<P>PROBLEM TO BE SOLVED: To smoothly switch a speed change mode from a fixed gear ratio mode into a continuously variable transmission mode without increasing motor physique. <P>SOLUTION: A hybrid vehicle drive control device includes: a boundary value determination means for determining a boundary value of output torque of a drive shaft; a range determination means for determining a range of the output torque of an internal combustion engine, which is capable of maintaining the output torque of the drive shaft to requested torque corresponding to requested drive force, based on the determined boundary value; a fixing means for fixing the engine output torque to a torque value within the determined range in a process that the engine output torque changes according to the change of the requested torque with the requested drive force changed; a compensation control means for compensating a difference between the requested torque and the fixed engine output torque by input/output of power; and a switch control means for switching the speed change mode while the engine output torque is fixed and the difference is compensated. <P>COPYRIGHT: (C)2013,JPO&INPIT |
