Abstract: The present invention sets an appropriate parking route according to a surrounding situation. A vehicle control device which controls traveling of a vehicle includes: a surrounding environment recognition unit which recognizes a surrounding environment of an own vehicle, detects a parking space, sets a target parking position and a travelable space; and a vehicle control unit which guides and controls the own vehicle to the target parking position in the travelable space. The vehicle control unit guides and controls the own vehicle to the target parking position without traveling the own vehicle in a space behind the target parking position.

Abstract: An evaporated fuel processing device for a forced induction internal combustion engine according to the present invention includes: a first purge path extending from the downstream of a purge control valve to an intake pipe at the downstream of a throttle valve; and a second purge path extending from the downstream of the purge control valve to an ejector provided in a reflux pipe providing communication between the intake pipe at the downstream of a compressor and the intake pipe at the upstream of the compressor. The evaporated fuel processing device switches first control characteristic data for the first purge path and second control characteristic data for the second purge path, when the first purge path and the second purge path are switched.

Abstract: Disclosed herein is a fuel injector for an internal combustion engine, which includes a high pressure pump for pressure feeding high pressure fuel of the internal combustion engine; a fuel rail for accumulating the fuel that has been pressure fed by the high pressure pump; an injection valve for injecting, into a cylinder, the fuel accumulated in the fuel rail; a fuel pressure sensor for detecting the pressure of the fuel that is accumulated in the fuel rail; an electromagnetic relief valve for discharging the pressure accumulated fuel of the fuel rail; and an electronic control unit for controlling opening and closing of the electromagnetic relief valve. The electronic control unit repeats the opening and closing of the relief valve to discharge the fuel pressure in stages so that the fuel pressure in the fuel rail is decreased down to the target fuel pressure.

Abstract: In an internal combustion engine provided with a high-pressure fuel pump, if the discharging rate of the high-pressure fuel pump is greater than the injection quantity of fuel injected from a injector with the high-pressure fuel pump remaining uncontrollable due to failure or the like, it is probable that the fuel pressure in a common rail unintentionally rises to affect the injector. A high-pressure fuel supply apparatus is provided to solve such a problem. A high-pressure fuel supply apparatus according to the present invention is configured such that if the high-pressure fuel supply apparatus or a control apparatus thereof causes malfunction to increase the pressure in the common rail, the pressure in the common rail does not exceed pressure affecting the flow characteristic and spray characteristic of the injector after recovery from the malfunctioning state.
