<P>PROBLEM TO BE SOLVED: To provide a vehicle drive control device that is capable of preventing the vehicle acceleration performance from being decreased due to a decrease of output torque in a drive source because of the suppression of a torsional resonance, which has no effect on a decrease of durability in a drive system. <P>SOLUTION: The device includes: estimating a resonance torque Tre when determined that a driving system torsional resonance has been generated; calculating a rate of increase RT in a peak value of the resonance torque Tre; deciding a torque decrease control execution determination threshold Tre1(1) for determining whether to decrease an output torque Te of the engine based on the rate of increase RT from a relationship stored beforehand; and suppressing the driving system torsional resonance by decreasing the output torque Te of the engine, when the resonance torque Tre exceeds the torque decrease control execution determination threshold Tre1(1). <P>COPYRIGHT: (C)2012,JPO&INPIT |
