A sliding mode observer is employed to estimate the system states, and both the observer\u2019s output and sensor measurements are used to perform voltage estimation using a Gaussian Process Regression (GPR) model. The residual between the estimated voltage and the ideal steering voltage is then compared to detect faults and compensate for the faulty voltage. The proposed method is validated through simulations on the CarSim\/Simulink co-simulation platform, including voltage estimation, fault diagnosis, vehicle front-wheel steering angle, and vehicle trajectory. The results show that the proposed method can accurately estimate faults and compensate the steer-by-wire system during steering motor faults, thereby improving steering stability and path-tracking performance.<\/jats:p>","DOI":"10.1177\/01423312251334848","type":"journal-article","created":{"date-parts":[[2025,6,25]],"date-time":"2025-06-25T02:28:39Z","timestamp":1750818519000},"page":"2115-2127","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Fault-tolerant control of steer-by-wire system based on Gaussian process regression"],"prefix":"10.1177","volume":"48","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-5037-0996","authenticated-orcid":false,"given":"Hongyan","family":"Jiang","sequence":"first","affiliation":[{"name":"School of Automotive Engineering, Harbin Institute of Technology, Weihai, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Na","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Automotive Engineering, Harbin Institute of Technology, Weihai, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tao","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Automotive Engineering, Harbin Institute of Technology, Weihai, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianfeng","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Automotive Engineering, Harbin Institute of Technology, Weihai, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Koji","family":"Mizuno","sequence":"additional","affiliation":[{"name":"Nagoya University, Nagoya, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Miao","family":"Chen","sequence":"additional","affiliation":[{"name":"Weihai Guangtai Airport Equipment Co.
