To provide a motor drive system that prevents excessive stop of a function when a control operation unit of a reaction force actuator or a steering actuator stops instantaneously.SOLUTION: Control operation units (HM-HS, TM-TS) of respective rear systems in actuators 10, 20 can be operated in a cooperative drive mode in which information mutually transmitted and received by inter-system communications H12, T12 is used in common to cause a motor drive unit to output torque. Respective cooperative control operation units (HM-TM, HS-TS) of a reaction force actuator 10 and a steering actuator 20 can operate in cooperation with each other based on the information mutually transmitted and received by inter-actuator communications HT1, HT2. If the target control operation unit HM stops during an operation, at least one of an adjacent inter-system communication H12 and an adjacent inter-actuator communication HT1 is interrupted, and then the target control operation unit HM restores, the adjacent inter-system communication H12 and adjacent inter-actuator communication HT1 are restored.SELECTED DRAWING: Figure 5

    【課題】反力アクチュエータもしくは転舵アクチュエータの制御演算部が瞬時的に停止したとき、過剰に機能を停止することを防止するモータ駆動システムを提供する。【解決手段】各アクチュエータ10、20内の裏系統の制御演算部同士(HM−HS、TM−TS)は、系統間通信H12、T12により相互に送受信した情報を共通に用いてモータ駆動部にトルクを出力させる協調駆動モードにより動作可能である。反力アクチュエータ10及び転舵アクチュエータ20における連携制御演算部同士(HM−TM、HS−TS)は、アクチュエータ間通信HT1、HT2により相互に送受信した情報に基づいて連携して動作可能である。着目制御演算部HMが動作中に停止し、隣接系統間通信H12又は隣接アクチュエータ間通信HT1の少なくとも一方が途絶した後、着目制御演算部HMが復帰した場合、隣接系統間通信H12及び隣接アクチュエータ間通信HT1を復帰させる。【選択図】図5
