保護乘 員、減少碰撞損傷的目的。 汽車發(fā)生碰撞事故時,若主要沖撞力是作用在汽車的前部,并在汽車中心軸線 30 度范圍以內(nèi)上十,可稱為前碰撞事故。 The introduction independently develops the intelligent type autosafety air pocket control system, this system mainly by the monolithicintegrated circuit, the sensor, the electric firing circuit and so onis posed, the use ignition control algorithm carries on thejudgement to the automobile acceleration signal, the output ignitionpulse. This system has the volume slightly, the reliability high, theantijamming ability is strong, may carry on from characteristic and so on diagnosis。 In order to reduce and avoids harnessing while the personnel receivesthe injury in the second collision, The crew protective system design goal is avoids or slows down the injury in the collision using the restraint system which in the crewmember and the vehicle the structural element collision creates。 專 科生畢業(yè)設計(論文) Abstract The auto safety aerocyst took one kind of auxiliary crew memberrestrains the condition, Has the collision when the automobile protects crew member39。本系統(tǒng)具有體積小、可靠性高、抗干擾能力強、可進行自診斷等特點 。汽車安全氣囊的基本思想是:在發(fā)生第一次碰撞后,第二次碰撞前,迅速在乘員和汽車內(nèi)部構件之間插入一個充滿氣體的氣囊,讓乘員 “撲 ”在氣囊上,通過氣囊上的排氣節(jié)流阻力吸收乘員的動能,使猛烈的第二次碰撞得以減緩,以達到保護乘員的目的。專 科生畢業(yè)設計(論文) 編號 畢業(yè)設計 (論文 ) 汽車安全氣囊的應用 Application of automobile airbag 院(系)名稱 專業(yè)名稱 學生姓名 學號 指導教師 2022 年 5 月 23 日 專 科生畢業(yè)設計(論文) 摘 要 汽車安全氣囊作為一種輔助的乘員 約束條件,在汽車發(fā)生碰撞時保護乘員的效用已越來越得到肯定,當今社會對安全氣囊的要求也越來越高,尤其是對智能安全氣囊的需求也越來越廣泛, 當汽車發(fā)生碰撞時汽車與汽車或汽車障礙物之間的碰撞稱為第一次碰撞,第一次碰撞導致了汽車速度的急劇變化。 所以安全氣囊作為一種防護措施已經(jīng)是必不可少了。 故設計的主要工作是對氣囊電路中的 CPU、加速度傳感器的選擇、繼電器的選擇及與電路有關的器件,如為防止錯點火而要設計一個點火電路、為防止信號干擾我們要加光隔離等一些措施。seffectiveness more and more to obtain the affirmation, Now the society also more and more is high to the security aerocystrequest。 The auto safety aerocyst basic thought is: After has the first collision, Before second collision, Rapidly inserts in the crew member and between the automobile interior ponent to fill the gas the aerocyst, Let the crew member throw oneself on the aerocyst, absorbs crewmember39。 Therefore designs the main work is to in aerocyst electric circuitCPU, the acceleration instrument choice, the relay choice and the andcircuit related ponent, like for prevents the wrong ignition but tohave to design a electric firing circuit, for prevented the meaconingwe must add the light isolation and so on some measures. Therefore Idesign the main work which does am to the security aerocyst hardwareelectric circuit implementation operation and to its principle of workcarry on the analysis, conducts the research to its application. Key word: Intelligence security aerocyst,; protection; security sensor; automobile collision. 專 科生畢業(yè)設計(論文) 目錄 摘 要 ........................................................................................................................................ 2 Abstract ...................................................................................................................................... 3 ( 1) 緒論 ................................................................................................................................ 6 ( 2) 安全氣囊簡介 ................................................................................................................ 7 ( 3) 安全氣囊的作用與分類 ......................................................................................... 7 ( 4) 安全氣囊的作用 .............................................................................................. 7 ( 5) 安全氣囊的分類 .............................................................................................. 7 ( 6) 安全氣囊系統(tǒng)的組成: ......................................................................................... 7 ( 7) 安全氣囊的工作原理: ......................................................................................... 8 ( 8) 安全氣囊的工作過程 ............................................................................................. 9 ( 9) 使用安全氣囊注意事項 ......................................................................................... 9 ( 10) 安全操作規(guī)范: ............................................................................................ 9 ( 11) 啟爆后安全氣囊的處理: .......................................................................... 10 ( 12) 安全氣囊的拆 卸: ...................................................................................... 10 ( 13) 安全氣囊的安裝: ...................................................................................... 10 ( 14) CAN 總線在汽車內(nèi)部的網(wǎng)絡研究 .......................................................................... 12 ( 15) CAN 簡介: ....................................................................................................... 12 ( 16) CAN 總線的概念 ....................................................................................... 12 ( 17) CAN 總線的特點 ....................................................................................... 12 ( 18) CAN 總線的結構特點 ....................................................................................... 13 ( 19) CAN 節(jié)點概述 ............................................................................................ 13 ( 20) CAN 總線的分層結構 ................................................................................ 14 ( 21) CAN 總線的位數(shù)值表示 ............................................................................ 14 ( 22) CAN 總線的通信距離 ................................................................................ 15 ( 23) CAN 報文的幀格式 ........................................................................................... 15 應答界定符 =1 個 隱性 ........................................................................................................... 16 ( 24) CAN 總線高
