This research studied the technique to measure the driving load and set up durability performance evaluation criteria of the automotive component. Therefore, the sensor gaging and calibration were performed to measure the RLDA(real load data acquisition) on low control arm of automotive components. The real driving test was carried out on 5 real roads like city road, local road, high way, nation road and unpaved road. The damage corresponding to high rank 1% driver condition was extracted on 5 real roads using log normal probability distribution. And the total damage of low control arm component was calculated reflecting the road driving mileage ratio of general drivers. The durability performance test load and cycle counts were suggested for the low-control arm component based on 2 years or 40,000km warranty standard.
