This article mainly from the car's active safety technology and passive safety technology two aspects elaborated the importance of car parts， and how to improve the safety of the car. Key words: automobile， active safety technology， passive safety technology As traffic tools of the modernization and absolute number increase sharply， traffic accidents are also increasing. Car accident has become severe global social issues. Undoubtedly， advanced auto safety facilities are the driving safety indispensable safeguard. So， we should start， from technology to research and development of high performance， high safety car， also want to strengthen the regular inspection in cars， so timely maintenance investigation， make cars often in good technical status， so as to improve the safety performance of the car. Here we introduced active safety technology and automobile car passive safety technology. Auto safety is according to the traffic accident happened before and after the classified. One is in a traffic accident take safety measures， especially before immediately will produce risk condition， drivers manipulate the steering wheel avoid or emergency brake to avoid traffic accidents. In the car， drive in usually to ensure the basic manipulation stability， drivers on the surrounding environment and to ensure the visual recognition sex drive the car itself， developed the basic performance ant-lock braking system (ABS)， prevent slippery drive system (ASR)， active suspension， power steering and four-wheel drive (4WD)， four-wheel steering (4WS)， lighting system， wiper， the rearview mirror， prevent from rear-end collision car alarm system and laser radar， etc. These security devices and technology， called active safety system， can also be called preventive security system. On the other hand， 3in order to reduce traffic accidents and company by personnel directly suffer degree， ensure company take staff and pedestrian safety， says the security for passive safety， can also be called conflict safety. When after the accident， in order to prevent disasters， including prevent the expansion of fire and make crew from traffic accident can extricate the security devices and systems， called prevent disaster expand security system. One．Automobile active security technology1. ABS braking system Ant-lock Braking System (Braking System， lock do by ABS computers as ABS)， hydraulic device， the wheel speed sensors， brake hydraulic pipeline and electrical wiring etc. Their structures are shown below. ABS tasseled for the car in various driving conditions braking performance and brake safety particularly important， especially is emergency braking， can make full use of the peak between tire and road surface adhesion properties， improve performance and reduce automobile fight sideslip braking distance， give full play to the braking performance， but also increase the automobile braking process control. So as to reduce the possibility of car accidents. No installation ABS car， if the driving force trample brake pedal， wheel will rapidly lower speed， and finally wheels stop turning， but body because of inertia remains forward sliding. This phenomenon was at the wheel and pavement occur between larger “slip“， appear this kind of situation， the car tires of automobile lateral spreads almost disappear， so poor force will appear the following phenomena: (1) Steering stability fall: the steering wheel is ineffective， vehicle tail manipulation of curl， serious when vehicle circles or appear folding phenomenon; (2) Handling fall: manipulate the steering wheel and short of steering requirements; (3) Braking distance extended: more than general braking distance. So， we can imagine to have installed ABS system of the car safety is very important. 2．the ASR drive torque control system ABS are used to prevent car braking process wheel lock， will wheel sliding rate control in 4ideal range， so as to shorten the braking distance， improve automobile braking direction stability and steering control， so as to improve the safety of the car. Along with the increase of vehicle performance requirements， not only in braking process required to prevent wheel lock， and asked the driver to prevent drive roller skating turn in the process， making cars in the direction stability， driving process steering control ability and acceleration performance， so are improved by the car drive torque steering system ASR (Accelerations Regulation) Slip. ASR is the perfect complement and ABS ASR， but most alone is set with ABS combined together， commonly used ABS/ASR says， called antiskid control system. ASR is mainly used to prevent car in the beginning， accelerate the wheels， guarantee slip in the car accelerated rate and improve the stability in bad pavement drive attached conditions. It makes no difference speed in the car lock ice roads and muddy road started and to improve its capacity， also can prevent high in speed by turning cars gliding pavement and rear lateral spreads phenomenon. Anyhow， prevent the wheel because ASR slip， can maximize the engine driving moment of cars had enough， ensure the longitudinal force， lateral force and manipulation of power， make cars in starting， steering and accelerate the process， in gliding and muddy road， in a mountain area downhill process can steadily driving， guarantees the safety， reducing tire wear and fuel consumption， and improves the car driving capability. 3．VDC system ABS/ASR system successfully solves the brake and the car when driven direction stability problem， but cannot solve the vehicle steering stability problem driving direction. For example when steering road， inevitably by lateral and longitudinal force， only local surface can provide full lateral and longitudinal force， the pilot can control vehicles. If the ground adhesion ability lower lateral， will damage cars driving ability predetermined direction. Rainy days cars driving， often high-speed steering lateral sliding out， it is the ground because of insufficient lateral adhesion ability. To resolve the issue， and developed countries automobile industry recently in ABS/ASR system on the basis of the development of dynamic Control system (into car Dynamics Control， the abbreviation VDC Vehicle). The system of the car brake， driving， suspension， steering， engine and so on various main assembly control system in function， structure organic ground comprehensive together， can make cars in all 5kinds of bad working conditions， such as ice road pavement， commuting， river bend pavement and took evasive action moving line， braking and acceleration and the downhill for different conditions， such as bearing， different type pressure and different levels of type wear all have good direction stability， to show the best driving performance. VDC applications， in braking， acceleration and steering aspects of driver's fully released request， is the car of active safety driving a new milestone. VDC of steering control system is mainly by driving for each wheel brake control and engine power output control to realize. For example， if the car turn left front wheel for steering the inadequate capacity tend to slip out of the corner， VDC system can measure imminent， just know lateral spreads left rear brake adopt appropriate measures. If at the same corner， because rear wheel tend to slip out of favor of lateral overmuch， VDC system is proper braking to front-right wheel failure， maintain the stability of the vehicle driving. In extreme cases， VDC system can also take reduce engine to reduce the power output， and to reduce the speed of the demand side adhesion ability to maintain the stability of the vehicle driving. Adopt VDC system， automobile in folio pavement or corner of pavement braking distance still can further reduce. 4． CCS cars cruise control system Auto cruise Control System (Cruiser Control System， abbreviation for CCS) is can make automobile work in engine favorable speed range， reduce driver's driving manipulate labor intensity， improve the driving comfort the automatic driving device. Car cruising system (CCS) role is required by the driver: after a normally-closed switch， no speed on the accelerator pedal can automatically keep the speed， make the vehicle with the fixed speed. Using this device， when on the highway after a long time， the driver driving not have to control the accelerator pedal， reduce fatigue， while reducing unnecessary speed change， can reduce save fuel. Auto cruise control system is the earliest development of the automotive electronic control system. This system uses another speed sensor， will speed signal input engine control microcomputer， by microcomputer control vacuum system work. This system can make use of the server， speed control switch lever and brake pedal on vacuum lift switches etc， its 6function and basic system the same. In this system， electronic control device can accord change of driving resistance， automatic regulation engine throttle Angle， make the speed constant. Such not only reduce unnecessary speed change， which saves fuel， also reduced the driver's burden. Two. Automobile passive safety technology1. Seat belt Car seat belt is a safety device， it can in car collision or sharp turn， make crew to keep its original position as possible without mobile and rotation， avoid collision with in-car hard parts caused damage. Seat belts and airbags， as modern cars are safety devices， but the long history of the former， popularize the scope. The seemingly simple seat belt actually not “simple“. Attention has been at the forefront of traffic safety， through the analysis of general motors after a car accident found: seat belt not only makes people protect the lives， can be in more than half of the accident to reduce or even eliminate drivers， motorists are the chance of injury. Car collision or unexpected emergency braking force generated great inertia， will allow the driver and passenger and car windscreen， steering wheel， seat， collision happened objects such as secondary to drive is caused extremely easily crew serious damage， even drive occupant seats or threw the apex， seat belts can will ride in the seat. Bondage personnel When has the accident， which can effectively prevent the collision， and its buffer role can absorbs a great deal of kinetic energy， reduce rides personnel extent of the injuries. Fasten your seat belt airbags play our role is also an important condition. Because the airbag to maximize role for the ride in the impact of the physical location， sitting instant action have extremely strict and the requirements. Otherwise， the airbag started strong instantaneous wallops to head are fragile site， may cause serious damage， especially for children， this damage can be fatal. Even the most ordinary three belts， try a can timely in crash that lived rides the bundle， ensure the upper part of a ride in the airbag fully extended range， make the airbag most effectively play efficacy. Accordingly， must not because the car is equipped with airbags and feel carefree seat belt fastened， only to reduce or eliminate the traffic accident happen. 72. The airbag When the front collision happened strong， because inertia， who rides the body forward fast moving， then seat belts and will try to “pull“ rides on person the body， absorb some of the impact energy， while the airbag with “the eyepiece trend“ inflatable and completely open; Then the rides the upper body will sink to airbags， gas also began from the vent air uniform escaping， and absorbed most of the impact energy; Subsequently， the ride back seat and return to the body. Above the whole process is almost always happens in a flash， who rides the completely in passive situation， in this case， the passive rely on auxiliary occupant protection system is the only option. Airbags development design is based on the protection on seat belt Co.， LTD; they cooperate with each other to ride the play the auxiliary protective effect. Seat belt usage in under the condition of the crew， balloon help reduce chest， head and facial injuries in the seriousness of the collision. When car collision happened before， the first is the car to stop motion， car under the action of inertial force crews to go forward with the original speed still sport. Not wearing a seatbelt crews will and steering dish， front windscreen together， so it can be severely hurt; Wearing a seatbelt as car stop the crew can stop moving forward movement and gradually. If collision violent， crew forward movement of the seat belts， even faster in the complete stop before motion， still and in-car things together. If this fashion in steering the disk or within the popup balloon inflated dash， it can protect the occupant reduce the possibility of car together with things， more uniform dispersion head， chest， absorb the impact energy of movement， thus crew has added effect of seat belts. In addition to seat belts and airbags outside car passive safety technology includes car bumper， automobile safety glass， security body， occupant head and neck protection system (WHIPS)， etc. These vehicles to improve the safety performance has very important contribution Three. Automobile active safety new technology1. Eye Car skills Eye Car technology can make each driver eyes in the same relative height， guarantee of pavement and the surrounding a six-lane unimpeded sight and best visibility. This technology 8can also offer a specific driving environment. Eye Car through the use of first-class motor mobile automatic will different figure driver's eyes tuned to the same height to solve the problem， meanwhile， visibility of steering dish， brake and accelerate pedals and floor and the central adjustment to constitute console to their respective driving conditions. Meanwhile to the former pillar design， will it again from drivers sights removed. Because the bus driver received the most crucial information generally have 90% from outside， acquired through the eyes observe. So， this improvement for vehicle safety is of great significance. 2. Cam Car technology Cam Car technology aims to help improve the driver of perception. The technical features are: (1) Installed in the car to camera system on both sides before to make drivers can bypass the large vehicle behind a car or see ahead of pedestrians. In a typical driving situation in the crowded traffic， the pilot of the centre-left cornering could more easily view the opposite of vehicles. (2) Side after buy video camera provides broader visual profile of vision. The camera coverage than traditional rearview mirror wants wide， especially for the adjacent driveway. (3) Installed in a car， the four miniatures sectored form to decorate after a camera can obtain the car panoramic perspective. Image via electronic synthesis， has the zoom and 160 ° wide-angle ability. (4) “night eye“ (Night Eye) camera can be in low illumination conditions， when the car is in reverse gear， even in a dark cases can also provide car close range after small images. Four. Automobile passive safety new technology1. Future airbags (1) It cans inflatable screen system. This is a new safety design; its basic principle is to protect in-car occupant's head， when that happens it will carry on the air， air after the tent shape is swelling. (2) Tubular inflatable structure head air sac. This system for supplement current side protection system， still stopover in protecting the chest and abdomen， brachial ministry， 9to head protection were insufficient. It with rigid body structure， the door body protective just beams， side air sac， can form a complete side safe defend net， this will be the future security protection trend. (3) Head support system. Head support system generally called the headrest， vehicles which the headrest， with seats， not just for comfortable fact is more important to safety. Vehicle if in an emergency brake， the body will have strong to and fro， because the principle of inertia occupant body swinging， especially neck must follow. If no head support buffer headrest， neck injury caused by damage is very surprising. (4) The external airbags. 2. Adaptive constraint technology system (ARTS) New adaptive constraint technology system (ARTS) use a series of sensors to monitor the driver seat， seat belt use， in front of the occupant take quality and location and intensity of the collision of the collisions and collision force direction， then according to the specific information such as the collision of each front airbag characteristics of the crew on regulated. The system can further reduce due to improper airbag for crew on the damage， especially for smaller front row figure crew. 3. Automobile energy-absorbing direction column Auto absorbing in automobile direction tubing through collisions of redistribution to steering wheel wallop， would wallop path to deliver shunt quickly， making the minimum of load on the steering wheel. The steering column by hollow tubes and steering bearings form. Traditional hollow tubes and the steering column steering bearings is integral， steering shaft top and steering connections， the connecting with direction below. And suck can direction string of characteristic is will the steering column in two， divided into unblock steering column and the steering column under two parts; Inside of the steering shaft also divided into two sections， with outgoing quarter agencies between them connected. Once a collision make direction， outgoing quarter mechanism has displacement bottom tailor-made steering shaft will fold， under the steering column move on the steering column， to achieve “indented within“ and thus expand space reduce damage.Five. The tire pressure monitoring system10In a car's tyros high-speed process， all drivers fault is the most worry and the most difficult to prevent， is also sudden traffic accident happened important reasons. According to statistics， China highway in the traffic accident is caused due to 70% of a flat tire， and in the U.S. this ratio is as high as 80%. How to prevent a blowout has become an important task of safe driving. According to the national quality supervise center of rubber tires in the expert analysis， maintain the standard tire pressure driving and the timely discovery tire is to prevent leakage of key blowout. Tire Pressure and Monitoring System (TPMS) - car Tire Pressure Monitoring System will no doubt is the ideal tool. The system is mainly used in automobile driving to tire pressure real-time automatic monitoring; to a flat tire and depression are the police， in order to ensure safety. Drivers from the monitors can know each tire pressure value， when tire pressure below the club set pressure limit， monitor will automatically alarm. Anyhow， car active safety technology and passive safety technology for the safety of automobile driving is very important， and besides， such as environmental factor， artificial factor of the vehicle safety is also very important. Therefore， we must be prepared to all aspects of requirements and technology， to ensure the safety of vehicle driving. 11汽車安全系統(tǒng)技術(shù)研究分析摘要汽車各部件的好與壞將直接影響汽車行駛的安全性，直接關(guān)系著人們的生命安全和財(cái)產(chǎn)安全。本文主要從汽車的主動(dòng)安全技術(shù)和被動(dòng)安全技術(shù)兩方面來闡述汽車各部件的重要性，及如何提高汽車行駛的安全性。關(guān)鍵詞：汽車、主動(dòng)安全技術(shù)、被動(dòng)安全技術(shù)隨著交通工具的現(xiàn)代化進(jìn)程加快和絕對(duì)數(shù)量的急劇增長，車禍也不斷增加。交通事故已成為嚴(yán)峻的全球性社會(huì)問題。毋庸置疑，先進(jìn)的汽車安全設(shè)施是行車安全不可缺少的保障。所以，我們要從技術(shù)上入手，努力研究開發(fā)高性能、高安全性的汽車，同時(shí)也要加強(qiáng)對(duì)在用汽車的定期檢查，以便及時(shí)維修調(diào)查，使汽車經(jīng)常處于良好的技術(shù)狀況，以提高汽車行駛的安全性能。這里我們重點(diǎn)介紹汽車主動(dòng)安全技術(shù)和汽車被動(dòng)安全技術(shù)。汽車的安全性是按交通事故發(fā)生的前后加以分類的。一方面是在交通事故發(fā)生之前采取安全措施，特別是即將發(fā)生危險(xiǎn)狀態(tài)時(shí)，駕駛者操縱方向盤避讓或者緊急制動(dòng)以避免交通事故發(fā)生。汽車在通常的行駛中，為確保駕駛者的基本操縱穩(wěn)定性，對(duì)周圍環(huán)境的視認(rèn)
