摘要:
A feed screw mechanism includes a feed screw shaft connected to a drive source and formed with first screw threads on an outer circumferential surface thereof, and a displacement nut, which is screw-engaged with respect to the feed screw shaft through a plurality of balls. The displacement nut is supported with respect to a slider that makes up an electric actuator by a pair of pins. The pins are inserted and fixed in first pin holes formed in the slider, and distal end portions of the pins are inserted respectively into second pin holes formed in the displacement nut.

A parking assist device for assisting parking operation to a target parking position includes an initial position setting device for setting an initial position of the target parking position to park a vehicle, a designation display showing the target parking position, a display position calculation device for calculating an initial display position of the designation display showing the target parking position at a screen showing vehicle surroundings based on the initial position determined by the initial position setting device, and an initial display position shifting device for shifting the initial display position of the designation display to a position within a display range on the screen in case the initial display position calculated by the display position calculation device is positioned outside of the display range on the screen.
摘要:
A vehicle information processing apparatus provided in a vehicle is provided with a TPMS valve that includes an air pressure sensor which obtains a tire air pressure as wheel information and a wheel-side communication device that transmits the wheel information and an ID unique to that wheel-side communication device at regular intervals; an ECU which receives the wheel information from the wheel-side communication device in each TPMS valve via a vehicle body-side communication device and processes that wheel information; and an onboard battery which supplies power to the ECU. Upon receiving a command to shift into a verification mode while power is being supplied from the onboard battery, the ECU performs a predetermined verification based on a signal transmitted at regular intervals from each wheel-side communication device. After receiving the command to shift into the verification mode, the ECU remains in the verification mode until a preset condition is satisfied.

A parking-assist device for an automotive vehicle comprises an imaging unit which creates an image of an exterior behind the vehicle. A target-parking-position input unit inputs a target parking position to park the vehicle when requested. A target-parking-position memory access unit stores the target parking position and reads the stored target parking position when requested. A vehicle-travel-amount detection unit detects an amount of travel of the vehicle. A parking-route determining unit calculates a parking route from a current position of the vehicle to the target parking position. A display unit displays the created image and displays one of the target parking position inputted and the stored target parking position read on the created image in a superimposed manner.
