To provide a control system of a hybrid vehicle which can be safely stopped by cutting transmission of driving force for travel to a pair of drive wheels when a prescribed abnormality occurs.SOLUTION: A control system 80 comprises: (a) a first control device (HV-ECU 82) which determines the driving force for travel of a hybrid vehicle 10; (b) a second control device (ECU 88 for power transmission control) which controls a solenoid drive circuit 88b of a second electromagnetic valve SC2 for controlling the connection/disconnection state of a hydraulic engagement device (start clutch WSC) in order to output the determined driving force for travel to a pair of drive wheels 32; and (c) a signal line 52 which transmits to the solenoid drive circuit 88b a cutting control signal Scut output from the first control device in order to cut transmission of the determined driving force for travel to the pair of drive wheels 32 when the first control device detects a prescribed abnormality.SELECTED DRAWING: Figure 1 【課題】所定の異常が発生した場合に一対の駆動輪への走行用駆動力の伝達を切断して安全に停止させられるハイブリッド車両の制御システムを提供する。【解決手段】制御システム８０は、（ａ）ハイブリッド車両１０の走行用駆動力を決定する第１制御装置（ＨＶ－ＥＣＵ８２）と、（ｂ）決定された走行用駆動力を一対の駆動輪３２に出力させるために、油圧式係合装置（発進クラッチＷＳＣ）の断接状態を制御する第２電磁弁ＳＣ２のソレノイド駆動回路８８ｂを制御する第２制御装置（動力伝達制御用ＥＣＵ８８）と、（ｃ）第１制御装置が所定の異常を検出した場合に、一対の駆動輪３２への決定された走行用駆動力の伝達を切断するために第１制御装置から出力された切断制御信号Ｓcutをソレノイド駆動回路８８ｂへ伝送する信号線５２と、を有する。【選択図】図１
