The automotive companies are therefore paying attention on the development of vehicle safety auxiliary systems. The systems are divided into the passive and active safety equipments. The passive safety equipment includes safety seat belt, SRS, Anti-Lock Brake System and Breakable Steering Wheel, while the active safety equipment has also caught much attraction, such as VOLVO`s Blindspot Information System (BLIS), Volkswagen`s IAS and ATSHID headlight. All the devices are to improve the safety for drivers as well as pedestrians. Driver’s behavior and driving environment are highly concerned with driving safety. In recent days, the passive safety equipments are no longer satisfied with the requirement of the driving safety for people. Instead, the active safety system can ensure the driving safety to avoid car accidents. According to traffic data, there are high rate of car accidents at night than day time, which is caused by bad visibility because of bad weather conditions. Lots of automotive companies are engaged in developing Forward Looking Infrared Radar (FLIR) system, but the price is expensive. Nowadays, Image Intensification has effectively recognized object resulting from night time uncertainties. The study is to develop Driver’s Viewer Enhanced System (DVES) by using Image Intensification technique for night driving. With the advancement of electro-optical and night vision technology, DVES provides the driver with better distance, scene, and obstacles recognition for night driving, so car accidents are decreased. DVES’s function has been tested in the laboratory and practical automotive in this study. The results meet the requirement of driver. In addition, the price of DVES is less expensive than FLIR.
