【正文】 Automobile passive 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 incar 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 重慶交通大學(xué)二 O 一二 屆畢業(yè)設(shè)計(jì)（ 論文） 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。 譯文 almost always happens in a flash, who rides the pletely 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。 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 plete stop before motion, still and incar 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 technology 1. Eye Car skills Eye Car technology can make each driver eyes in the same relative height, guarantee of pavement and the surrounding a sixlane unimpeded sight and best visibility. This technology can also offer a specific driving environment. Eye Car through the use of firstclass motor mobile automatic will different figure driver39。 譯文 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 centreleft 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 160 176。 its basic principle is to protect incar occupant39。 譯文 (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, to head protection were insufficient. It with rigid body structure, the door body protective just beams, side air sac, can form a plete side safe defend , 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 fortable 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) Ne
