Abstract: A vehicle includes: an engine driven with gasoline; a lid member opening/closing an opening of an accommodation room that accommodates a nozzle receiving unit when gasoline is supplied; a rotating electric machine driven on electric power; a charging/power feeding unit receiving electric power; a lid member opening/closing an opening of an accommodation room accommodating a charging/power feeding unit; and an open/close control mechanism setting the other of the lid member and the lid member in the closed position when one of the lid member and the lid member is set in the open position.

Abstract: A vehicle (100) includes: a battery (B1, B2); a motor generator (MG2) driven by electric power stored in the battery (B1); a coupling unit (41) for electrically coupling the battery (B1, B2) to an external commercial power supply (55); and a controller (60) for operating an electrical component (43) and performing failure diagnosis of the electrical component (43) in a case where the vehicle and the external power supply can be electrically coupled by operating the coupling unit (41). As a result, there can be provided a vehicle that can be charged from outside and allows early detection of a failure without reducing a distance that can be traveled, and a method for failure diagnosis of the vehicle.

Abstract: An internal combustion engine is provided with a VVT mechanism capable of adjusting overlap period in which both intake and exhaust valves are open. The internal combustion engine is also provided with a recirculation mechanism that recirculates exhaust gas to the intake side. An EGR map from which internal EGR amount based on the VVT mechanism and external EGR amount based on the recirculation mechanism are derived in accordance with engine speed and engine torque is prepared. The EGR map is realized as a four-dimensional map that also takes engine intake air temperature and engine coolant temperature into account. By performing EGR control in consideration of these parameters, the occurrence of knocking during EGR control can be suppressed, and an improvement in fuel consumption and the like can be achieved with certainty.
