Abstract: Reliability and durability are two important technical indicators in automobile research and development. A research-and-design and testing organization can increase inherent quality attributes by adopting a systematic approach based on statistical tools and clearly defined processes. The process affects the design phase, validation through testing, and quality assurance in production. On the basis of reliability growth theory and the Duane model, this study established an estimation method for the definition of the target mileage and specific test cycles in reliability growth testing. A construction method for defining test conditions was proposed that adopts the theory of the design of experiments. The simulation was conducted under a variety of typical test conditions including differing operation times, loads, and logistics modes to predict customer use and detect failures. Failure cases were then analyzed in detail. At the same time, a reliability growth prediction model was established on the basis of the initial test data and used for test process tracking and risk control.
