摘要： To shorten a time required to predict collision with other vehicles, a collision prediction device includes: a detection unit configured to detect each of a front, a rear, and a side of other vehicles located around a vehicle from a captured image of one frame in which surroundings of the vehicle are imaged; and a determination unit configured to determine a likelihood of collision with the other vehicles based on a detection result of the detection unit. The determination unit determines that the likelihood of collision with the other vehicle of which only the front or only the rear is detected is high in the other vehicles of which one or more of the front, the rear, and the side are detected by the detection unit.

摘要： A locking pin driving mechanism includes a motor, a preceding gear, a round gear, a feed screw and a slider. The feed screw is coaxially fixed to the round gear. A locking pin is mounted in the slider. A center axis of the locking pin and a center axis of the feed screw are each disposed in parallel with a center axis of a vehicle inlet. An interaxial distance between the center axis of the vehicle inlet and the center axis of the feed screw is set to be larger than an interaxial distance between the center axis of the vehicle inlet and the center axis of the locking pin.

摘要： A tilting mechanism of a view device for a vehicle has a configuration in which a rotating section is rotatably supported on a shaft of a fixed portion. A helical compression spring is fitted onto the shaft. A plate is attached to the free-end side of the shaft via a washer. An outer circumferential surface of the shaft and a center hole of the washer include respective different diameter portions. A gap g in a radial direction is formed between the outer circumferential surface of the shaft and an inner circumferential surface of the center hole of the washer. The tilting mechanism includes a deviation mechanism. The deviation mechanism makes the gap g become narrow or zero at the different diameter portions at at least one place, the different diameter portions facing each other, by making the washer move relative to the shaft in the radial direction.

摘要： A reference position setting method according to the present disclosure is a reference position setting method for setting a reference position for recognizing whether or not an operation unit displayed as a virtual image has been operated. The reference position setting method includes: a step of displaying a marker displayed as a virtual image larger than an object approaching the marker; a step of detecting the object approaching the marker; and a step of making a color or shade of the outer edge of the marker different from a color or shade of the center of the marker after the step of detecting the object.

摘要： A mirror display apparatus that subjects a mirror optical element to pulse voltage driving so that a reflectivity in a mirror mode can be changed by means of a duty cycle of the pulse voltage is provided. A mirror display apparatus includes a monitor display device and a mirror optical element disposed on the front side of the monitor display device. The mirror optical element includes a liquid-crystal panel with a reflection-type polarizer disposed on the back side thereof. The mirror optical element has a reflectivity and a transmissivity that are changed in respective directions opposite to each other via electric driving using a voltage applied to the liquid-crystal panel. A control circuit drives the liquid-crystal panel using a pulse voltage and performs control to change the reflectivity and the transmissivity of the mirror optical element by changing a duty cycle of the pulse voltage.

摘要： A manual operation element includes a locking active surface and an unlocking active surface. A locking displaceable element includes a locking passive surface and an unlocking passive surface. When the manual operation element is operated in a locking direction, the locking active surface engages with the locking passive surface and displaces the locking displaceable element toward a locked position. When the manual operation element is operated in an unlocking direction, the unlocking active surface engages with the unlocking passive surface and displaces the locking displaceable element toward an unlocked position. When the locking displaceable element performs a displacement operation electrically, neither the locking active surface and the locking passive surface nor the unlocking active surface and the unlocking passive surface engage with each other in an entire area or more than half area of a displacement range of the locking displaceable element.

摘要： This invention intends to prevent generation of abnormal sound. A motor shaft is inserted in a center hole of a worm and fitted in the center hole in a direction around an axis of the worm. A distal end of the worm is received in a bearing recess. A worm wheel engages with the worm. A radial gap and rotational play are formed between the motor shaft and the center hole of the worm. A radial gap is formed between the distal end of the worm and the bearing recess. The gap between the distal end of the worm and the bearing recess is formed so as to have a size that prevents an outer circumferential surface of the distal end of the worm and an inner circumferential surface of the bearing recess from coming into contact with each other when the worm is rotating.

摘要： This invention relates to a view angle adjustment mechanism that causes a view element tilting section holding a view element to be supported by a tilting support section via a plurality of concentric pivots having different diameters, to perform view angle adjustment. An inner pivot is assembled by forcible fitting using elasticity of either or both of a pivot convex and a pivot concave without screw fastening. An outer pivot includes a plurality of elastic pieces disposed at a plurality of positions in a circumferential direction of a curved surface of either or each of both of an outer-pivot convex surface and an outer-pivot concave surface. The outer pivot is assembled by the forcible fitting in the inner pivot. The assembly causes the plurality of elastic pieces to elastically abut on an opposed curved surface.
