Automotive functions involve distributed end-to-end computation in automotive cyber-physical systems (ACPSs). The automotive industry is highly cost-sensitive to the mass market. This study presents a resource-cost-aware fault-tolerant design methodology for end-to-end functional safety computation on ACPSs. The proposed design methodology involves early functional safety requirement verification and late resource cost design optimization. We first propose the functional safety requirement verification (FSRV) method to verify the functional safety requirement consisting of reliability and response time requirements of the distributed automotive function during the early design phase. We then propose the resource-cost-aware fault-tolerant optimization (RCFO) method to reduce the resource cost while satisfying the functional safety requirement of the function during the late design phase. Finally, we perform experiments with real-life automotive and synthetic automotive functions. Findings reveal that the proposed RCFO and VFSR methods demonstrate satisfactory resource cost reduction compared with other methods while satisfying the functional safety requirement.<\/jats:p>","DOI":"10.1145\/3162052","type":"journal-article","created":{"date-parts":[[2018,9,6]],"date-time":"2018-09-06T12:10:50Z","timestamp":1536235850000},"page":"1-27","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["Resource-Cost-Aware Fault-Tolerant Design Methodology for End-to-End Functional Safety Computation on 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, Changsha, China"}]},{"given":"Gang","family":"Zeng","sequence":"additional","affiliation":[{"name":"Nagoya University, Nagoya, Japan"}]},{"given":"Jiyao","family":"An","sequence":"additional","affiliation":[{"name":"Hunan University, Changsha, China"}]},{"given":"Renfa","family":"Li","sequence":"additional","affiliation":[{"name":"Hunan University, Changsha, China"}]},{"given":"Keqin","family":"Li","sequence":"additional","affiliation":[{"name":"State University of New York, New Paltz, NY"}]}],"member":"320","published-online":{"date-parts":[[2018,9,5]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.future.2012.05.004"},{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1145\/1059816.1059823"},{"volume-title":"Proc. 23rd IEEE Real-Time Systems Symposium.
