To accelerate system testing at early development stage of the product development process, model-based system testing capabilities are developed. Urgent needs to enhance efficiency, reduce costs and protect the vehicle test drivers from hazardous incidents were among its original intentions. Most of the steering related bench performance tests were confined to basic measurements of mechanical or electrical characteristics of the steering system in the past. But the advent of digital era has made the bench test go beyond the rigs to simulate the realistic behavior of UUT under vehicle environment. Actuators can now be individually controlled with precision to generate realistic forces and positions in real-time to produce vehicle dynamics which are calculated by vehicle model. By using this kind of methods most of the steering maneuvers could be realistically reproduced with no hazard to the driver and steering characteristics could be investigated in a more quantified manner.
For High-risk steering maneuvering, the entire spectrum of the vehicle tests were listed and screened to choose the most-hardto-quantify and risky tests and tests were conducted by using HILS platform on a correlated and automated basis. Beside this, reinforced performance testing conditions were developed for validation of steering dynamics and BSR related testing. And by doing that prepared for the autonomous driving test base onwards. The methods proposed here allowed to keep the model based test as references for steering performances, thus, increasing the effectiveness of the validation by reducing the number of vehicle test at an early stage of development.
