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.

By promoting air circulation, heat and humidity are reduced more efficiently. A vehicle seat ventilation mechanism includes: a body case which is provided in a cushioning material of at least one of a seat cushion and a seat back and whose interior is an air circulation space; a fan disposed in the body case; and an exhaust port which is provided at a position apart from the fan and discharges an air stream created by air suction by the fan. The air stream enhances the comfort of a microclimate condition on a vehicle seat side which is a rear side of a contact surface, and with this microclimate condition, a thermal environment on a seat occupant side having an increased causal factor of discomfort is replaced, thereby making it possible to enhance the comfort of the clothing microclimate.
