Description of the Invention (1) [Technical Field] The present invention is a collision detection device related to automobiles. In particular, it is a device that responds to the direction of collision and makes it a means of safety for cabin crew. [Prior Art] In the past, there was a collision detection device that detects both a frontal collision and a side collision of a vehicle and activates the airbag for front collision and the airbag for side collision. This collision detection device is generally provided with acceleration sensors in the front-rear direction and the left-right direction, and it is a method of actuating each airbag by individually processing accelerations in the three directions of front, left, and right. However, the development of this direction can also be applied to bevel collisions. In addition, a device that vectorizes the acceleration data in the three directions described above and then processes it is proposed so that the side airbag will not be deployed when the front collision (refer to Japanese Patent Laid-Open No. 6-5 5 9 9 No. 3 and Japanese Patent Laid-Open No. 6-5 6 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0) That is, this device detects the accelerations Gy and Gx in the front-rear direction and the left-right direction as shown in Fig. 6, and then calculates the vector f from the settings fy and fx obtained by processing such as time integration. Specifically, the size is (f X 2 + f y 2) 2,1 and the direction is β = t a η — 1 (f x / f y). However, a critical value is set for the magnitude of this vector to determine whether the airbag is operating. Furthermore, it is determined in this direction that the airbag should be deployed. However, the actual collision morphology system is very complicated. The above-mentioned direction S f changes with time, not only the size but also the direction. For example, the dotted line 4 0 changes the vector f.

The purpose is to provide not only the size of the vector but also the direction to change, and the selection of safety means to make it a detection device.

The direction is 0 ’and θ " are different. Therefore, the infinite way of the vector will cause the problem of setting the critical value. In view of the past technology, the present invention changes the acceleration of collisions with time. It is printed from more than two kinds of cabin crews, and the safety measures of the cabin crews are timely. [The invention is to enable the collision sensor to be detected when it is placed in the car. The above method is to set at least one person to measure the axis. The calculation method is safe and manual.] It solves the problem of getting on the vehicle, and the detection device is activated in response to it. According to the occurrence of a collision, several passengers are in the direction of the vehicle, and the safety measures mentioned above are selected and segmented. However, the specific description of the subject is different from the impact shape: the two overtimes are divided, and the impact acceleration as a virtual corresponding to the front direction of the person ’s safety corresponds to the state of the present invention (the two types in front are not Set in the means of speed-sensing collision; the front-left direction, the collision detection and the detection of the collision of the shaft should be equipped with two collisions, and the appropriate safety means an acceleration acceleration test to make the actuation system to be different.

The various options and means of the tester's side of the test device are directed to the direction of the two, and the above, with the aforementioned composition, the aforementioned -5 This paper size is applicable to the Chinese National Standard (CNS) Α4 specification (210X297 mm) 304923 atB7 Printed by the Beigong Consumer Cooperation Department of the Central Standards Bureau of the Ministry of Economy V. Description of the invention (3) The safety measures of the multiple crew members of the vehicle and before the vehicle is detected The first acceleration sensor for acceleration in the rear direction, and the second acceleration sensor for detecting acceleration in the left-right direction of the vehicle, and at least 1 different from these in advance in the front direction, left direction, and right direction of the vehicle Direction, the collision detection axis as the direction of the imaginary detection of the conflict, and the components of each collision detection axis of each acceleration detected by the first and second acceleration sensors, and the actual acceleration is calculated after adding these components The acceleration component calculation means for the components of each collision detection axis, and the acceleration corresponding component calculation means for calculating the acceleration from the acceleration components to the components of each collision detection axis corresponding to the acceleration value, and the corresponding collision detection The axis sets the critical value comparison of the aforementioned acceleration-corresponding value components. If the critical value is exceeded, the start signal is output to each of the comparison means of the aforementioned crew safety means. Furthermore, the two acceleration sensors may be provided in the front-rear direction and the left-right direction of the vehicle. In addition, the comparison means is to provide a plurality of blocks corresponding to a plurality of groups formed by one or more safety means of the crew, and the acceleration corresponding to each of the blocks input to these blocks corresponds to 1 of the value component The sum of two or more sets the aforementioned critical values respectively. In addition, the other comparison means is to provide a plurality of groups corresponding to a plurality of groups formed by one or more safety means of the cabin crew, and the corresponding acceleration components of each of the accelerations input to these groups are respectively It is also possible to set the aforementioned threshold value through the AND or OR circuit, and select and activate the aforementioned plurality of crew members.

Invention Instructions (4 ) The collision detection device of the present invention having the above structure decomposes the acceleration detected by the sensors provided in two different directions into components of the collision detection axis. The components of the collision detection axes of the acceleration of the vehicle in the front-rear direction and the left-right direction are added separately, and the acceleration components of the collision detection axes can be obtained. Actually, the acceleration of each collision detection axis is a component corresponding to the value of the acceleration obtained by applying time integration or the like to the detected acceleration. Then, based on the acceleration of each collision detection axis and the components of each collision detection axis, the actuation means for the passengers are set in advance corresponding to each collision detection axis. In this case, since the collision detection axis is fixed, the threshold value can be easily set. However, the magnitude and direction of the actual acceleration becomes complicated, and it is only limited to detecting the collision in the direction of the collision detection axis when the component of each collision detection axis exceeds the critical value of the front speed, so it can be actuated corresponding to the collision detection Appropriate safety measures for crew members set in advance. In addition, the component of each collision detection axis of the actual acceleration can be obtained by multiplying the acceleration detected by the acceleration sensor by a certain coefficient, so the calculation is easy. Furthermore, since the collision detection shafts are provided in other oblique directions in the front direction and the left-right direction of the vehicle, the sensitivity to the collision of the inclined surface can be improved more than in the past when only collision detection in the front direction and the left-right direction of the vehicle is performed. Furthermore, when the two acceleration sensors are respectively installed in the front-rear direction and the left-right direction of the vehicle, the installation directions of the acceleration sensors are orthogonal to each other and coincide with the collision detection axes in the front-rear direction and the left-right direction of the vehicle, so It is necessary to calculate the acceleration in these directions, so it is composed (please read the precautions on the back before filling in this page) • τ This paper size is applicable to Chinese national standards (CNS specifications (2I0X297 mm) 304923 A7 Central Ministry of Economics staff Printed by the consumer cooperative B7___ 5. Description of the invention (5) It becomes simple. In addition, the aforementioned comparison means sets the critical value for the sum of one or more of the corresponding acceleration components of the aforementioned acceleration, and then the acceleration of the specific collision detection axis Corresponding to the value component, the acceleration of the other collision detection axis is added to the corresponding value component for evaluation, so that the collision of the fan across the two collision detection axes can be detected in the same way. In addition, the aforementioned comparison means corresponds to the acceleration corresponding to the value Set the aforementioned threshold value by AND or OR circuit to make it actuate the crew As a safety measure, not only the acceleration corresponding to the value component of the specific collision detection axis but also the acceleration corresponding to the value component of the other collision detection axis can be evaluated, so that the collision across the range between the two collision detection axes can be detected in a similar manner. The structure of the collision detection device is not only selected based on the magnitude of the collision acceleration (f x2 + f y2) 1/2 or the direction Θ2 ta n_1 (fx / fy) and makes it a safe means for actuating the crew, but it is calculated for each collision The two acceleration components of the two acceleration sensors of the detection axis are selected based on this calculation value and act to correspond to the safety measures of the crew for each of the collision detection axes. Therefore, the acceleration of the collision not only changes its magnitude with time It also changes, so you can choose from more than two kinds of cabin crew safety measures and make them operate appropriately. As a result, the direction of the collision can be detected with a simple structure, which can make the cabin crew safe according to the collision direction.

Invention description (10) TH1, f 3 > TH1, f 4 > TH1. When this is set, collisions in the direction of the collision detection axis where the other components of the time integral value are input to each critical value are detected, and collisions across the directions between these collision axes are transmitted to these collisions due to addition The components of the shaft are detected, so they are detected slightly the same. Second: The components f2 and f4 of the time integral values of the collision detection axes A2 and A4 transmitted to the slope direction are input across two critical values (TH1 and TH2, TH2 and TH3), respectively. Therefore, the critical value TH 2 corresponds to the impact of the near direction of the left or right direction, which is added to the components f 2 and f 4 of the collision detection axes A 2 and A 4 of these realms without moving The airbags 8 and 7 are set to larger values. For example, the critical mass TH 1 is set to f 1 + f 2CTH2 for the collision in the near direction in the front direction. The critical value is appropriately selected within the range satisfying 2 conditions. However, other critical values TH1 ~ TH 3 can be used as a weighted average value to measure the amount of collision absorption of the car body during collision. Next, the operation of the collision detection device will be described based on Figs. 2 and 3. In FIGS. 2 and 3, for example, when a collision with the acceleration G shown in FIG. 3 occurs, Gy and Gx are detected with the first and second acceleration sensing S 1 ′ S 2 and calculated based on the detected value The components f 1 to f 5 conducted to the time integral value as shown in the figure. However, the block 25 of the comparison means adds f 2 to f 4 completely, and is formed to exceed the critical value T Η 2, and the start signal 3 2 is output and the air wrap 5 and 6 ° before the collision is deployed. Block 2 4 adds f 1 and f 2, but because it is a collision in the near direction of the front and forward direction, it is formed below the critical value Τ Η 1 and is not output. This paper scale is applicable to the Chinese National Standard (CNS) VIII 4 Specifications (2 丨 ΟΧ297mm I-(please read the precautions on the back before filling in this page) -5 A7 B7 304923 V. Invention description (11) (please read the precautions on the back before filling in this page) 3 1 therefore does not deploy the right side airbag 8. In addition, f 4 and f 5 are added to block 26, but since f 5 is formed as a negative value, it is formed below the critical value TH3 and the start signal 3 3 is not output, so The left side air pocket is not deployed. 8. When a collision with an acceleration G in another direction occurs, the calculation is simple. Therefore, when a collision occurs, the air pocket configured in the vehicle is activated according to the direction of the collision. Second, to Figures 4 (a) and 4 (b) illustrate modified examples. As shown in Figure 4 (a) ), The angles θ 2 ′ and θ 4 ′ in the front-rear direction of the collision detection axes A 2 ′ and A 4 ′ in the direction of the inclined plane can be emphasized to collect the oblique protrusions in the front direction. ) As shown in the figure, the collision detection axis A 6 which is transmitted to the rear is set, and because the rear headrest of the vehicle is equipped with a rear airbag, it can be used as a collision detection device that can also respond to rear collisions. However, the collision detection axis Not limited to the above example, any number and direction can be set. The larger the number, the more accurately the direction and extent of the collision can be determined and it can be used as a safety measure for the crew. In addition, when the collision is detected and the pretensioner is activated at the same time, the safety of the crew can be more reliably protected. In this case, it is activated to all front collisions, side collisions, and rear collisions. In addition, With respect to FIG. 2, in the above-described embodiment, the comparison means 2 3 adds the value of the component of the predetermined number of time-transmitted components transmitted to the collision detection axis, and sets the critical value Τ Η 1 ~ T Η 3, but instead of this method, as shown in Figure 5, comparison means are provided on each collision detection axis, and a threshold value is set for each comparison means, and its start signal is output under the conditions of OR or AND To the corresponding airbags 5, 6, 7, 8 and the constitutive paper scale is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) -14-B7 Printed by the Consumer Cooperative Society of the Central Sample Bureau of the Ministry of Economy V.

[Industrial Utilization Possibilities] The collision detection device of the present invention is to calculate the two accelerations of the two acceleration sensors of each collision detection axis. The component is selected according to this calculation and operates on the safety means of the cabin crew corresponding to the collision detection axis, so the acceleration of the shock will not only change in size and direction but also change from 2 over time.
