Problems solved by technology

[0007] However, in the case of the above-mentioned conventional device, because the opening control of the airbag is performed according to the magnitude of the left-right direction component of the side part direction, so even in the case of a frontal collision, a large impact is input to the left-right direction. The airbag may be deployed, because the occupant usually moves forward during the frontal collision, so there is a problem that even if the side airbag is activated, the protection effect on the occupant is low, and the user's repair cost burden will increase on the contrary.

Embodiment Construction

[0016] Next, in order to explain the present invention in more detail, the best mode for carrying out the present invention will be described with reference to the drawings.

[0017] Fig. 1 is a diagram showing the overall configuration of an air bag control device according to Embodiment 1 of the present invention.

[0018] In FIG. 1 , the airbag control device according to Embodiment 1 of the present invention has: a front impact sensor (front acceleration detection means) provided in front of a vehicle 1 as a front and rear direction acceleration sensor for detecting acceleration in the front and rear directions of the vehicle 1 2, 3; Side impact sensors (side acceleration detection units) 4, 5, which are arranged on the left and right sides of the vehicle 1 and serve as side acceleration sensors for detecting the acceleration in the left and right directions of the vehicle 1; The front airbags 6 and 7 of the airbag; the side airbags 8 and 9 as the side impact airbags for p...

Abstract

Comprising an acceleration detection means (11) detecting the accelerations of a vehicle (1) in the longitudinal and lateral directions, a collision determination means (12) determining the head-on collision and the side collision of the vehicle based on an output detected by the acceleration detection means (11), and a drive means (13) developing an air bag (14) mounted at the front or the side of the vehicle based on an output determined by the collision determination means (12). The collision determination means suppresses the determination of the side collision based on information on the collision of the vehicle in the longitudinal direction included in the output detected by the acceleration detection means.

Description

technical field [0001] The present invention relates to an airbag control device for controlling the deployment of an airbag mounted on a vehicle, and more particularly to an airbag control device capable of suppressing damage caused by impacts other than side impacts such as frontal impacts Side impact with sudden deployment of airbags. Background technique [0002] In the past, the side impact sensor installed on the side of the front seat (or rear seat) was used to judge the magnitude of the impact acceleration of the left and right components of the vehicle. When the impact is large, it is controlled so that the side airbag and the curtain airbag Open (for example, refer to Patent Document 1). [0003] In addition, there is a device that integrates the output of the acceleration sensor in the front and rear directions, and the integral value is above the low threshold and below the high threshold, and integrates the output of the acceleration sensor in the left and righ...
