Automotive safety systems and technology research and analysisAs 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 , in order to reduce traffic accidents and company by personnel directly suffer degree, ensure company take staff a...
