Car accident has become severe glob

2、al 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 investig

3、ation, 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 traffi

4、c 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 t

5、o 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

6、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, in order to reduce traffic accidents and company by personnel directly suffer degree, ensure company ta

7、ke 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

8、 disaster expand security system. OneAutomobile active security technology 1. 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.

9、 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 dist

10、ance, 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 be

11、cause 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

12、 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 inst

13、alled ABS system of the car safety is very important. 2the ASR drive torque control system ABS are used to prevent car braking process wheel lock, will wheel sliding rate control in ideal range, so as to shorten the braking distance, improve automobile braking direction stability and steering contro

14、l, 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 steeri

15、ng 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 i

16、s 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 pr

17、event 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

18、 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. 3VDC system ABS/ASR system successfully solves the brake and the car when driven dire

19、ction 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

20、 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 A

21、BS/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 tog

22、ether, can make cars in all kinds 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 a

23、ll have good direction stability, to show the best driving performance. VDC applications, in braking, acceleration and steering aspects of drivers 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 con

24、trol 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 re

25、ar 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 a

26、bility 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 w

27、ork in engine favorable speed range, reduce drivers 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 spe

28、ed, 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

29、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 func

30、tion 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 drivers burden. Two. Automobile pa

31、ssive safety technology 1. 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 devic

32、es, 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 mor

33、e 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 driv
