The RCAR has been established in order to reduce maintenance costs and insurance rate of vehicle. Total cost of ownership of the vehicle is sum of the costs of the purchasing and operating, it is an important factor affecting sales. Some tests such as 40% offset 10dgree rigid wall are performed by RCAR to estimate the damageability and repairability of vehicle. And the insurance rate is determined by test results. Vehicle manufacturer and component supplier have tried to reduce insurance rate and repair cost. In this paper, the movable cooling module mounting solution has been developed that can protect the expensive components such as cooling module from damage in low speed crash. The RCAR low speed crash test result conducted by using crash cart and vehicle, cooling module did not damage. Mass production vehicle was assessed by KART (Korea Insurance Repair Research and Training Center) in 2010.

Front End Module is assembled to the front area of the vehicle. In the case of front crash, the Front End Module should be able to absorb the impact and the deformation of Front End Module should be minimized. If the vehicle’s hood deformed by crash is opened, it can make the wind shield of vehicle broken and injure passengers. Because deformed and opened hood can cause the additional accidents, the stiffness supporting hood is very important. The stiffness of all developed vehicles must be verified in the development stage through Hood Latch Retention Test. And the test must be controlled strongly. The stiffness supporting hood & latch has the relationship with the Front End Carrier’s upper structure. The Higher inertia of Upper Section is advantageous, but the upper section can not be secured often because of vehicle’s styling or engine room layout or limitation of cost & weight , ETC, and these factor is different according to the vehicles We have developed several vehicle’s Front End Module since 1999 and we will introduce some kinds of knowhow from the development history of 2 vehicle’ Front End Module.
