Problems solved by technology

[0004] However, in a structure that uses an occupant restraint system such as an airbag to restrain the vehicle occupant in the event of a vehicle accident, there is a high demand for improved occupant restraint performance. Therefore, in order to detect the occurrence of a vehicle collision quickly and reliably, it is necessary to construct a system that can effectively improve the detection characteristics. Higher requirements for sensors

Embodiment approach

[0082] In addition, the present invention is not limited to the above-described embodiments, and various applications and modifications are possible. For example, each of the following embodiments to which the above-described embodiments are applied can also be implemented.

[0083] In the above-mentioned embodiment, as shown in FIG. 3 , the case where the coil sensor 131 erected in the vertical direction is held in an oblique shape by the holding member 134 while being rotated by the angle θ in the counterclockwise direction is described. However, in the present invention, , the arrangement of the coil sensor 131 is not limited to this, and can also be appropriately changed as required. Here, FIGS. 7 and 8 show other embodiments different from the arrangement of the coil sensor 131 in FIG. 3 .

[0084] In the embodiment shown in FIG. 7 , the coil sensor 131 standing upright in the vertical direction is held in an oblique shape by the holding member 134 while being rotated cl...

Abstract

A collision detecting device which is installed in a vehicle comprises a coil sensor provided with a plurality of detecting sections having different distances relative to a door outer panel, respectively, in a direction perpendicular to the extending direction of the door outer panel.

Description

technical field [0001] The present invention relates to a technique for deriving information on displacement of vehicle constituent parts. Background technique [0002] Conventionally, various vehicle collision sensors are known that detect the occurrence of a collision when a vehicle accident occurs. For example, the following Patent Document 1 discloses a structure in which when a side collision occurs to a vehicle, if the side door of the vehicle receives an impact exceeding a certain value, the insulation state of the two conductors is released to conduct with each other, thereby serving as an electric current. A signal detects the occurrence of a side collision of the vehicle. [0003] Patent Document 1: JP-A-5-45372 [0004] However, in a structure that uses an occupant restraint system such as an airbag to restrain the vehicle occupant in the event of a vehicle accident, there is a high demand for improved occupant restraint performance. Therefore, in order to detec...
