CONTROL SYSTEM FOR HYBRID VEHICLE

To inhibit clutch engagement during an engine restart from affecting cooperative regenerative braking control and switching of braking in a hybrid vehicle having a P module onboard, a control system for the hybrid vehicle includes an engine, a motor, a K clutch, drive shafts, a hydraulic friction brake system, and a controller capable of performing cooperative regenerative braking control. When start of the engine is requested during the cooperative regenerative braking control, the controller performs a first process of transitioning to braking only by the frictional brake system, a second process of raising an engine revolution speed while engagement of the K0 clutch is initiated after completion of transitioning to the braking, and a third process of controlling the engine to resume operating at a timing after the engine revolution speed increases to match a motor revolution speed after the engagement of the K0 clutch is initiated.
