Impact detecting device

摘要

An impact detecting device includes a first impact detecting portion, a determining portion and an informing portion. The first impact detecting portion detects an impact applied to an object equipped to a vehicle. The determining portion determines that the object has received the impact when a detection result of the first impact detecting portion is greater than a first impact determination threshold. The informing portion informs that the object has received the impact, when the determining portion determines that the object has received the impact.

1. An impact detecting device comprising:
a first impact detecting portion detecting an impact applied to an object equipped to a vehicle; a determining portion determining that the object has received the impact when a detection result of the first impact detecting portion is greater than a first impact determination threshold; an informing portion informing that the object has received the impact, when the determining portion determines that the object has received the impact; and a second impact detecting portion detecting an impact applied to the vehicle, wherein the determining portion determines that the object has received the impact, when the detection result of the first impact detecting portion is equal to or smaller than the first impact determination threshold and when a first integrated time that the detection result of the first impact detecting portion exceeds a second impact determination threshold is greater than a first integrated time determination threshold, the second impact determination threshold being smaller than the first impact determination threshold; the determining portion determines that the object has received the impact, when the detection result of the first impact detecting portion is equal to or smaller than the second impact determination threshold and when a second integrated time that the detection result of the first impact detecting portion exceeds a third impact determination threshold is greater than a second integrated time determination threshold, the third impact determination threshold being smaller than the second impact determination threshold, and the second integrated time determination threshold being greater than the first integrated time determination threshold; and the determining portion determines whether the detection result of the first impact detecting portion is greater than the first impact determination threshold, when a detection result of the second impact detecting portion is greater than a fourth impact determination threshold that is smaller than the third impact determination threshold.
