2、fety systems and technology research and analysisAbstract: auto parts of good and bad will directly affect the safety of the car, are directly related to the peoples life safety and security in wealth. This article mainly from the cars active safety technology and passive safety technology two aspec
3、ts 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 s
4、evere 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 maintenanc
5、e 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 i
6、n 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 environ
7、ment 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
8、, 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, in order to reduce traffic accidents and company by personnel directly suffer degree, ensure
9、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, call
10、ed prevent 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 sh
11、own 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 br
12、aking 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, b
13、ut 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: th
14、e 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
15、 have installed 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 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
