Problems solved by technology

[0004] However, in the conventional apparatus as described above, since, for example, a plurality of acceleration sensors need to be provided for each door, or a plurality of side sensors need to be provided on both sides of the vehicle body to determine on which side a side collision has occurred, the Large number of parts required

[0084] A side collision detection system 10 serving as a collision detection structure according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 7 . First, a schematic configuration of a side collision-resistant occupant protection system 12 for protecting an occupant of an automobile 11 as a vehicle to which the side collision detection system 10 is applied will be explained, and then the side collision detection system 10 will be explained. In the drawings, arrows FR, UP, IN, and OUT indicate a forward direction relative to the vehicle, an upward direction relative to the vehicle, a laterally inward direction relative to the vehicle, and a laterally outward direction relative to the vehicle, respectively.

[0126] FIG. 20 shows the front of a car 11 using a side impact detection system 70 according to a second embodiment of the invention in a schematic plan view. As shown in the figure, the side impact detection system 70 differs from the side impact detection system 10 in that the side impact detection system 70 includes a two-stage load transfer structure 72 serving as a load transfer structure instead of the two-stage load transfer structure 22 .

[0127] The side collision detection system 72 transmits the load caused by the side collision to the side collision detection G sensor 20 arranged in the floor tunnel 18 in two stages. The two-stage load transmission structure 72 according to the second embodiment can be constructed such that, as shown in FIG. The stage load increases after a side impact and then the rate of change of the load decreases in the second stage input. A specific description is given below.

[0152]24 shows in a block diagram corresponding to FIG. 3 a side impact detection system 100 and an occupant protection system 12 for protecting an occupant against a side impact including the side impact detection system 100 according to the third embodiment of the present invention. As shown in FIG. 24 , the side collision detection system 100 differs from the side collision detection system 70 according to the second embodiment in that instead of the side collision air safety device 15 and the CPU 32, the side collision detection system 100 includes: A safety air device 105 serving as an occupant protection device has a safety air device 102 for high load and a safety air device 104 for low load; and a CPU 106 serving as a collision determination section and a controller. Specifically, although not shown in the drawings, the side impact detection system 100 includes a two-stage load transfer structure 72 as the load transfer structure of the present invention or one of the t...

Abstract

The side impact detection system (12) includes a two-stage load transmitting structure (22) that transmits to a floor tunnel, in which a side impact-detecting G sensor is provided, load caused by a side impact at a predetermined impact speed Vp in two stages having a predetermined time lag in such a manner that the load transmitted or the rate of change in the load differs between the first-stageload transmission and the second-stage load transmission.

Description

technical field [0001] The present invention relates to a collision detection structure, a collision detection system and method, and an occupant protection system and method for detecting a collision with a vehicle to which the present invention is applied. Background technique [0002] A technique is available that ensures the detection of a collision by providing a door with multiple acceleration sensors and performing detection based on the signals from the multiple acceleration sensors so that the acceleration caused by the collision is not confused with the acceleration caused when the door is closed. Acceleration (see Japanese Patent Application Publication No. 6-219237 (JP-A-6-219237)). [0003] Meanwhile, an occupant protection device for a vehicle is available, which includes: a lateral acceleration sensor arranged at a central area with respect to the vehicle width direction and used to determine on which side a side collision has occurred; a left side sensor whic...
