A method of controlling a hybrid vehicle including an engine, a motor, a starter, a friction engagement element provided between the engine and the motor, and a mechanical oil pump which is driven by the motor and supplies oil to the friction engagement element, is provided. When the friction engagement element is in a disengaged state, a first traveling mode using the motor is performed. When it is in an engaged state, a second traveling mode at least using the engine is performed. The method includes, when the first traveling mode is unperformable, starting the engine by the starter to perform the second traveling mode, activating the motor and performing a hydraulic pressure control for shifting the friction engagement element from the disengaged to engaged state after starting the engine. The hydraulic pressure control uses at least the hydraulic pressure from the mechanical oil pump driven by activating the motor.

A grille shutter control device of a vehicle includes an encapsulation structure covering an engine, a grille shutter provided at an opening formed at a front wall portion of the encapsulation structure, an actuator configured to move the grille shutter to open/close the opening, and a controller configured to control the actuator. The controller determines whether or not heat damage occurs on a related component relating to the engine upon key OFF, closes the grille shutter upon key OFF in the case of determining that the heat damage will not occur, and opens the grille shutter upon key OFF in the case of determining that the heat damage will occur.

An undercarriage structure of a motor vehicle has a pair of front frames, a pair of floor frames integrally connected with rear ends of the front frames, a floor panel attached to the floor frames, and side sills extending in a front/rear direction and being connected with the sides of the floor frames. The floor frames, the side sills and the floor panel together form closed sections extending in the front/rear direction.
