Abstract: To inhibit clutch engagement during an engine restart from affecting cooperative regenerative braking control and switching of braking in a hybrid vehicle having a P2 module onboard, a control system for the hybrid vehicle includes an engine, a motor, a K0 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.

Abstract: A control device of a vehicle is provided. The vehicle includes a drive source, wheels, a driving force transmission shaft provided in a driving force transmission path extending from the drive source to the wheels, and an accelerator position sensor for detecting a depression amount of an accelerator pedal. The control device estimates or detects a torsion angle of a drive source side end portion of the shaft with respect to a wheel side end portion, an instruction to the drive source to generate a first torque corresponding to the depression amount of the pedal when the depression is determined to have started, and instructs the drive source to generate a second torque when a change rate of the torsion angle is determined to have inverted from a positive rate to a negative rate for the first time after the depression is determined to have started.
