The　driving　range　of　multiaxle　steer-by-wire　vehicles　is　significantly　affected　by　the　consumption　of　vehicle　cornering　resistance　power　(VCRP).　This　article　addresses　this　issue　by　proposing　a　novel　energy-saving　steering　control　strategy　to　effectively　reduce　VCRP　by　optimizing　slip　angle.　Initially,　a　general　VCRP　model　is　developed　to　establish　a　relationship　between　VCRP　and　the　slip　angles　of　each　tire.　Later,　an　adaptive　nonsingular　terminal　sliding　mode　control　method　is　proposed　to　balance　control　energy　and　state　errors.　In　addition,　an　energy-saving　steering　angle　optimization　method　is　proposed　based　on　the　VCRP　model,　which　achieves　an　optimal　steering　angle　configuration　by　optimizing　the　slip　angle.　The　efficacy　of　the　proposed　control　strategy　in　energy-saving　is　evaluated　by　hardware-in-the-loop　tests.　The　experimental　results　exhibit　noteworthy　reductions　of　more　than　21%　and　45%　in　VCRP　under　both　high-friction　and　low-friction　conditions　of　high　speed,　respectively,　compared　to　the　traditional　Ackerman　steering　control　strategies　while　maintaining　excellent　steering　stability.
