To provide a vehicular drive system that can change characteristics of a motor, in a vehicle that is driven by the motor as a running driving source, in response to wide request output.SOLUTION: A vehicular drive system is provided with a motor having a stator and a rotor installed in the stator, which drives a drive wheel of a vehicle by rotation of the rotor. The rotor has a plurality of secondary conductors arranged in a circumferential direction at a site outside in a radial direction thereof and a plurality of permanent magnets arranged in the circumferential direction at a side closer to inside in the radial direction than the plurality of secondary conductors. The system further comprises an ECU and a motor ECU which can switch a driving mode of the motor into a synchronous operation mode and an asynchronous operation mode. The ECU and the motor ECU are configured to switch the synchronous operation mode to the asynchronous operation mode (S7) on the basis of request output to the motor (S4).SELECTED DRAWING: Figure 9

    【課題】モータを走行駆動源とする車両において、広い要求出力に応じて、モータの特性を変更することが可能な車両用駆動システムを提供する。【解決手段】ステータと、ステータ内に設けられたロータと、を有し、ロータの回転により車両の駆動輪を駆動するモータを備える車両用駆動システムである。ロータは、径方向外側の部位で周方向に並ぶ複数の二次導体と、これら複数の二次導体よりも径方向内側の部位で周方向に並ぶ複数の永久磁石と、を有している。モータの駆動態様を、同期運転モードと、非同期運転モードと、に切替え可能なECUおよびモータECUをさらに備えている。ECUおよびモータECUは、モータへの要求出力に基づいて(S4)、同期運転モードから非同期運転モード(S7)への切替えを行うように構成されている。【選択図】図9
