Abstract: Controllability is an essential aspect in the evaluation of Automotive Safety Integrity Levels (ASIL) according to ISO 26262. However, few studies have provided a test method to quantify controllability in the real world. This paper proposed a systematic method to conduct a controllability test for the hands-off function in the field. It incorporates human factors into the whole process to ensure the results' reliability. This method provides a step-by-step test process that can be served as an example for test process standardization. Based on this method, a field test involving over 100 samples is conducted, aimed at exploring the controllability boundaries of typical failure types of highway pilot functions. In addition, this study has also unveiled several interesting findings related to driver's reaction and operation.
