Two　different　car　traction　control　methods　were　studied　and　some　dynamic　characteristics　were　found.　Firstly,　a　new　electric　rear　driving　car　with　two　DC　motors　driving　independently　is　controlled　by　a　combined　system.　The　combined　system　consists　of　a　feed-forward　control,　a　feedback　control　and　a　SRC.　Secondly,　a　built-in　permanent　magnet　synchronous　motor　is　selected　as　its　driving　motor.　A　motor　driving　system　with　a　current　loop　and　a　speed　loop　was　developed.　The　current　loop　consists　of　maximum　torque　per　ampere　control　and　field　weakening　control.　Some　simulation　work　was　done　based　on　MATLAB/Simulink　software.　The　simulation　study　showed　the　control　system　can　make　the　electric　vehicle　work　well.　©　(2012)　Trans　Tech　Publications,　Switzerland.
