In view of the fact that the variable spacing strategy cannot adapt to the complex and variable deceleration conditions, an improved variable time headway strategy is proposed, which changes with the deceleration time and deceleration of the preceding vehicle. Based on this, the upper controller of adaptive cruise control based on model predictive control is designed, and numerical simulation of the variable time headway spacing strategy is performed, which verifies the effectiveness of the improved variable time headway strategy. The results show that the spacing strategy proposed in this paper can more smoothly keep up with the preceding vehicle, and improve driving safety, comfort and road utilization.<\/jats:p>","DOI":"10.3233\/jifs-202107","type":"journal-article","created":{"date-parts":[[2020,11,6]],"date-time":"2020-11-06T11:47:29Z","timestamp":1604663249000},"page":"1471-1479","source":"Crossref","is-referenced-by-count":6,"title":["Adaptive cruise control system based on improved variable time headway spacing strategy"],"prefix":"10.1177","volume":"40","author":[{"given":"Jin","family":"Mao","sequence":"first","affiliation":[{"name":"School of Mechanical and Precision Instrument Engineering, Xi\u2019an University of Technology, Xi\u2019an, Shaanxi, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lei","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Mechanical and Precision Instrument Engineering, Xi\u2019an University of Technology, Xi\u2019an, Shaanxi, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kai","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Mechanical and Precision Instrument Engineering, Xi\u2019an University of Technology, Xi\u2019an, Shaanxi, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jinfu","family":"Du","sequence":"additional","affiliation":[{"name":"School of Mechanical and Precision Instrument Engineering, Xi\u2019an University of Technology, Xi\u2019an, Shaanxi, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yahui","family":"Cui","sequence":"additional","affiliation":[{"name":"School of Mechanical and Precision Instrument Engineering, Xi\u2019an University of Technology, Xi\u2019an, Shaanxi, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","reference":[{"issue":"2","key":"10.3233\/JIFS-202107_ref1","doi-asserted-by":"crossref","first-page":"229","DOI":"10.1109\/TITS.2005.848359","article-title":"Range Policy of Adaptive Cruise Control Vehicles for Improved Flow Stability and String Stability[J]","volume":"6","author":"Zhou","year":"2005","journal-title":"IEEE Transactions on Intelligent Transportation Systems"},{"key":"10.3233\/JIFS-202107_ref2","doi-asserted-by":"crossref","unstructured":"Greg M. , Mike M. and Mark B. , Towards an understanding of adaptive cruise control[J], Transportation Research Part C 9(1), 2001.","DOI":"10.1016\/S0968-090X(00)00022-X"},{"issue":"1","key":"10.3233\/JIFS-202107_ref4","doi-asserted-by":"crossref","first-page":"597","DOI":"10.1080\/00423119408969077","article-title":"A Comparision of Spacing and Headway Control Laws for Automatically Controlled Vehicles\u2218, 1[J]","volume":"23","author":"Swaroop","year":"1994","journal-title":"Vehicle System Dynamics"},{"issue":"2","key":"10.3233\/JIFS-202107_ref5","doi-asserted-by":"crossref","first-page":"229","DOI":"10.1109\/TITS.2005.848359","article-title":"Range Policy of Adaptive Cruise Control Vehicles for Improved Flow Stability and String Stability[J]","volume":"6","author":"Zhou","year":"2005","journal-title":"IEEE Transactions on Intelligent Transportation Systems"},{"issue":"4","key":"10.3233\/JIFS-202107_ref6","doi-asserted-by":"crossref","first-page":"198","DOI":"10.1109\/TITS.2003.821341","article-title":"On spacing policies for highway vehicle automation[J]","volume":"4","author":"Santhanakrishnan","year":"2003","journal-title":"IEEE Transactions on Intelligent Transportation Systems"},{"issue":"4","key":"10.3233\/JIFS-202107_ref10","doi-asserted-by":"crossref","first-page":"657","DOI":"10.1109\/25.260745","article-title":"Autonomous intelligent cruise control[J]","volume":"42","author":"Ioannou","year":"1993","journal-title":"IEEE Transactions on Vehicular Technology"},{"issue":"4","key":"10.3233\/JIFS-202107_ref13","doi-asserted-by":"crossref","first-page":"1365","DOI":"10.1109\/25.728529","article-title":"Nonlinear spacing policies for automated heavy-duty vehicles[J]","volume":"47","author":"Yanakiev","year":"1998","journal-title":"IEEE Transactions on Vehicular Technology"},{"key":"10.3233\/JIFS-202107_ref15","unstructured":"Luo L.H. , \u2018Research on control strategy of vehicle adaptive cruise system\u2019 (Shanghai Jiaotong University Press, Shanghai, China, 2013)"},{"issue":"5","key":"10.3233\/JIFS-202107_ref17","doi-asserted-by":"crossref","first-page":"1480","DOI":"10.1109\/TVT.2004.832386","article-title":"Should adaptive cruise-control systems be designed to maintain a constant time gap between vehicles?
