According　to　an　electrical　vehicle　(EV)　construction　and　working　principle,　a　dynamic　model　governing　its　motion　was　established.　A　built-in　permanent　magnet　synchronous　motor　was　selected　as　its　driving　motor　and　a　mathematical　model　about　the　motor　working　principle　was　described　also.　To　get　good　motion　effect,　a　motor　driving　control　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.　The　speed　loop　is　based　on　a　sliding　mode　control.　To　make　the　EV　working　more　smooth,　stable　and　safer,　its　traction　control　includes　driving　motor　control　and　wheel　braking　control.　During　some　acceleration　or　cornering,　wheel　braking　control　is　introduced　to　keep　driving　wheels　in　good　slip　states,　especially　to　make　the　car　in　a　good　stable　and　safe　state.　Simulation　study　based　on　MATLAB/Simulink　showed　the　control　strategy　developed　here　can　make　the　EV　work　well,　even　when　it　runs　on　some　asymmetric　road.
