In fact, the driver\u2019s controllability is variable during the runtime phase, such that the execution process of safety-critical automotive functions is a human-interaction-aware process between the driver and ACPS. To adapt to the changes in the driver\u2019s controllability, this article studies the human-interaction-aware adaptive functional safety processing for multi-functional ACPS in two main phases. In the design phase, where the driver\u2019s controllability is fixed at the highest level (i.e., C3), we obtain the approximate optimal priority sequence of safety-critical functions without exhausting all sequences by proposing the refined exploration method. In the runtime phase, where the driver\u2019s controllability level is variable (i.e., C0, C1, C2, or C3), we propose the human-interaction-aware task remapping method to autonomously respond to the change of the driver\u2019s controllability. Examples and experiments confirm that the proposed adaptive functional safety processing can reduce overall task redundancy of safety-critical automotive functions while meeting their functional safety requirements, shorten the overall response time of safety-critical automotive functions, and increase the slack time for non-safety-critical automotive functions.<\/jats:p>","DOI":"10.1145\/3337931","type":"journal-article","created":{"date-parts":[[2019,8,9]],"date-time":"2019-08-09T12:22:28Z","timestamp":1565353348000},"page":"1-25","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Human-Interaction-aware Adaptive Functional Safety Processing for Multi-Functional Automotive Cyber-Physical Systems"],"prefix":"10.1145","volume":"3","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6625-0350","authenticated-orcid":false,"given":"Guoqi","family":"Xie","sequence":"first","affiliation":[{"name":"Hunan University, China"}]},{"given":"Yang","family":"Bai","sequence":"additional","affiliation":[{"name":"Hunan University, China"}]},{"given":"Wei","family":"Wu","sequence":"additional","affiliation":[{"name":"Hunan University, China"}]},{"given":"Yanwen","family":"Li","sequence":"additional","affiliation":[{"name":"China Automotive Technology and Research Center, China"}]},{"given":"Renfa","family":"Li","sequence":"additional","affiliation":[{"name":"Hunan University, China"}]},{"given":"Keqin","family":"Li","sequence":"additional","affiliation":[{"name":"State University of New York, New Paltz, NY"}]}],"member":"320","published-online":{"date-parts":[[2019,8,9]]},"reference":[{"key":"e_1_2_1_1_1","volume-title":"Road vehicles-functional safety (Dec","author":"ISO","year":"2018","unstructured":"ISO 26262 : Road vehicles-functional safety (Dec . 2018 ).
