碩士 === 大葉大學 === 設計研究所 === 91 === Because of high density of vehicles in Taiwan most drivers may find it difficult to park a car along the roadside quickly with only traditional rearview mirror. Currently nearly all car manufacturers are using CCD camera helping drivers see the rearview behind the car and using radar to tell the distance between the car and the outside objects. Where to install and how to operate the CCD camera effectively is a design issue worth systematic studying. This research employed experimental method to evaluate the appropriate position for installing CCD camera. The experiments were carried out in the daytime and nighttime. Three different objects were put behind the car respectively, and CCD camera was installed in three different locations in the rear portion of the car. For each testing condition test drivers were requested to move the car backward until they felt the car at a safe distance away from the outside objects. The distance between the car and the object was measured. Testing results show that installing the CCD camera in the rear upper end of the trunk lid can best assist the driver keep the shortest safe distance between the car and outside objects. Based on the testing results a complete set of device with outer form covering inner functional parts was designed, and prototype was made to demonstrate the design outcome. It is expected that with appropriate production consideration the design can be put into production and commercialized.
