PROBLEM TO BE SOLVED: To ensure intended traveling performance by inhibiting a change in current, resulting from a change in the voltage of a motor.SOLUTION: A vehicle drive control device comprises: an engine 13 that drives front wheels 12FL, 12FR; an electric motor 14 that drives rear wheels 12RL, 12RR; and a generator 17 that generates power by obtaining power of the engine 13, and supplies the electric motor 14 with the power thus generated. Additionally, the control device generates a magnetic field current command value Ifc for the generator 17 and controls power generation according to this magnetic field current command value Ifc. Then, the control device estimates an amount ΔV of change in the voltage of the electric motor 14, and corrects the magnetic field current command value Ifc according to this amount ΔV of change in the voltage. The amount ΔV of change in the voltage of the electric motor 14 is estimated according to the voltage change speed E' of the electric motor 14 and the response time constant Ts of the generator 17.

    【課題】モータの電圧変動に伴う電流の変化を抑制し、意図した走行性能を確保する。【解決手段】前輪12FL・12FRを駆動するエンジン13と、後輪12RL・12RRを駆動する電動モータ14と、エンジン13の動力を得て発電し、発電した電力を電動モータ14へ供給するジェネレータ17と、を備える。また、ジェネレータ17に対する界磁電流指令値Ifcを生成し、この界磁電流指令値Ifcに応じて発電を制御する。そして、電動モータ14の電圧変化量ΔVを予測し、この電圧変化量ΔVに応じて、界磁電流指令値Ifcを補正する。電動モータ14の電圧変化量ΔVは、電動モータ14の電圧変化速度E’、及びジェネレータ17の応答時定数Tsに応じて予測される。【選択図】図3
