To inhibit clutch engagement during an engine restart from affecting cooperative regenerative braking control and switching of braking in a hybrid vehicle having a Pmodule onboard, a control system for the hybrid vehicle includes an engine, a motor, a Kclutch, 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 Kclutch 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 Kclutch is initiated.

Control system for hybrid vehicle

To provide a control device for a vehicle capable of controlling the torque of a drive source so as to appropriately balance the suppression of body vibrations and the securing of a transient response during acceleration or deceleration. This control device for a vehicle includes an accelerator position sensor that detects the accelerator opening, a torque adjustment mechanism such as a throttle valve that adjusts the torque of an engine as the drive source of the vehicle, and a powertrain control module (PCM) that controls the torque adjustment mechanism based on the accelerator opening. The PCM sets the target acceleration of the vehicle based on the accelerator opening, sets the target torsion angle of the drive shaft based on the target acceleration, sets the target torque of the engine based on the target torsion, and controls the torque adjustment mechanism based on the target torque.
