Abstract: The present invention provides a fuel pump capable of preventing the occurrence of cavitation near a seat member in a valve mechanism. The fuel pump includes a plunger adapted to reciprocate, a pressurizing chamber adapted to increase and decrease its volumetric capacity through the reciprocation of the plunger, and a relief valve mechanism adapted to return a fuel to the pressurizing chamber. The relief valve mechanism includes a relief valve, and a seat member having a valve contact portion for seating the relief valve thereon. The relief valve is disposed closer to the plunger than the seat member. The seat member has an annular groove portion which forms a space communicating with the pressurizing chamber, between the annular groove portion and a second chamber (a fixing portion) surrounding the outer peripheral surface of the seat member. The space is provided at a position farther from the plunger than the valve contact portion.

Abstract: A first circuit board 16 and a second circuit board 17, each of which have mounted thereon circuit components for controlling and driving an electric motor, are stacked with a space left therebetween such that one board surface of the first circuit board and one board surface of the second circuit board are opposed to and face each other in the direction of a rotation shaft 14 of the electric motor. In a state that the first circuit board 16 and the second circuit board 17 are attached to the motor housing, a receptacle connector 28 mounted on the first circuit board and a plug connector 34 mounted on the second circuit board form a “board-to-board connector” by which the circuit components of the first and second circuit boards are electrically connected.

Abstract: A vehicle parking control device has a processor and a memory to control the vehicle from a starting to a target parking position. The vehicle control device includes an obstacle detection unit detecting obstacles around the vehicle, a travelable area setting unit setting an area where the vehicle can travel based on a position of the obstacles, and sets the target parking position in the travelable area, a route generation unit calculating a travel route to the target parking position in the travelable area, and a parking execution unit that causes the vehicle to travel toward the target parking position on the basis of the travel route. The route generation unit generates a route from a parking start position to the target parking position, and corrects a distance of the section to a predetermined distance when the distance of the section is less than the predetermined distance.

Abstract: In one mode, with a vehicle control apparatus, a vehicle control method, and a vehicle control system according to the present invention, a control command is output for operating an actuator unit mounted in a vehicle, so as to obtain a control moment including at least one of a roll moment, a pitch moment, and a yaw moment that are generated for the vehicle before a curve on a traveling road on which the vehicle runs, based on a physical quantity about a curvature ahead on the traveling road and a physical quantity about a speed of the vehicle. In this way, the passenger's sense of security when the vehicle runs on the curve may be improved.

Abstract: A water-impermeable cover includes an opening part extending toward an opening part of a holding ring of a stub shaft of a propeller shaft, and is disposed to face the opening part of the holding ring. The water-impermeable cover is fixed at a position to face the opening part of the holding ring of the stub shaft, and the opening part of the water-impermeable cover extends to approach the opening part of the holding ring: therefore, even if muddy water etc. scatters obliquely toward the opening part of the holding ring, the risk of muddy water etc. entering the opening part of the holding ring is reduced, and as a result, also the risk of muddy water etc. entering an interior of a center bearing is reduced.
