A mobile warning apparatus according to one aspect of the present disclosure includes a velocity calculator, a position determiner, and an eliminator. The velocity calculator calculates one or more relative velocities of one or more observed points. The position determiner determines whether the observed points are in a predetermined proximity extent. The eliminator eliminates, in response to determination that the observed points are in the predetermined proximity extent, all the observed points from a warning target.

Mobile warning apparatus

An object detection apparatus is mounted to a vehicle and detects an object by a reflected wave of a probe wave. The object detection apparatus calculates a relative velocity of the object to the vehicle, estimates an azimuth of the object relative to the vehicle, and corrects the estimated azimuth. The object detection apparatus generates a velocity-azimuth curve that indicates a relationship between the relative velocity of the object and the azimuth of the object that is calculated based on a theoretical mounting angle of the object detection apparatus, supplies a weight to an azimuth error that is an error between the velocity-azimuth curve and the estimated azimuth, based on the estimated azimuth, and calculates a correction value of the estimated azimuth by calculating, as an actual mounting angle deviation of the object detection apparatus, a weighted average value of the azimuth error to which the weight is supplied.

Object detection device

The alarm device includes an acquisition part, an alarm judging part, a notification part, a static extraction part, a shielding boundary setting part, and a suppression part. The acquisition part acquires reflection point information and object information. The alarm judging part determines whether the object is an alarm candidate for each of the objects. The notification part issues a notification regarding the alarm candidates. The static extraction part extracts static reflection points. The shielding boundary setting part sets an approximate straight line as a shielding boundary by robust estimation. The suppression part suppresses notification of alarm candidates that are on the opposite side of the shielding boundary.

Alarm device for vehicle

A driving assistance device includes an object detection unit, an acquisition unit acquiring a first value of a relative speed of an approaching object with respect to an own vehicle, a ghost determination unit, and an assistance determination unit. The ghost determination unit calculates a second value of the relative speed of the approaching object in accordance with a speed of the own vehicle and a value of the relative speed of a following object located between the own vehicle and the approaching object; calculates, as a speed difference, an absolute difference between the first value of the relative speed and the second value of the relative speed; calculates, as an azimuth difference, an absolute difference between an azimuth of the following object and an azimuth of the approaching object; and determines whether the approaching object is the ghost target based on the speed difference and the azimuth difference.

Driving assistance device

A vehicle seat includes: a cushion that has a main portion that configures part of the seat cushion or the seat back and is placed in the seat width direction middle portion of the cushion and a pair of right and left side support portions that project toward the seat upper side or the seat front side relative to the main portion; and a cover that has side support portion cover portions and a main portion cover portion, with both seat width direction end portions of the main portion cover portion being joined to the side support portion cover portions, and with the seat width direction dimension of the main portion cover portion being longer than the seat width direction dimension of a surface on the seated occupant side of the main portion in a deformed state resulting from an occupant being seated.

Vehicle seat

A vehicle seatincludes: a seatback frame forming framework of a seatback that supports the back of a seated occupant; and a seatback pad that is attached to the seatback frame, and that includes a pair of left and right side support sections respectively disposed at both seat width direction end portions of the seatback pad, a main section disposed between the pair of left and right side support sections, and soft angled sections that are provided to seat front side end portions on both seat width direction end portions of the main section and are softer than a seat width direction intermediate portion of the main section, and that are angled such that seat front side faces of the soft angled sections are disposed further toward the seat front side on progression toward the seat width direction outer side.
