  • Publication number: 20210327274
    Abstract: 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.

    Abstract: 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.
