For　the　drive　torque　can　be　controlled　independently　in　a　four　in-wheel-motor　drive　vehicle,　in　order　to　improve　vehicle　handling　and　stability,　based　on　the　yaw　control　strategy,　the　new　control　strategy　has　been　proposed　that　the　driving　torque　of　inner　and　outer　wheels　were　changed　in　the　same　range　at　the　same　time　while　turning.　A　four-wheel-driving　vehicle　model　is　built　in　Adams/View,　and　conducted　a　joint　simulation　with　Simulink.　The　results　show　that　during　the　angle　step　input　response,　increased　the　inner　torque　is　much　better　than　reduce　the　inner　torque　or　same　inner　and　outer　torque.　In　contrast　to　same　inner　and　outer　drive　torque,　increasing　the　inside　of　drive　torque,　the　maximum　overshoot　of　yaw　rate　is　reduced　of　5.73%,　the　smallest　overshoot　of　yaw　rate　is　decreased　1.88%,　the　convergence　time　is　cut　down　10.59%.　It　shows　that　the　use　of　electric　wheel　technology　with　appropriate　control　strategy　can　greatly　improve　the　car＇s　handling　and　stability.　©　2011　IEEE.
