This paper proposes an anti-slip traction control for electric vehicle based on torque observer. The proposed traction control consist of direct torque control and unknown input observer. The direct torque control has the performance of fast response and accuracy torque control and the unknown input observer is a proper scheme to estimate a load torque which depends on the unknown road condition. The torque command of a traction motor is compensated according to a load torque estimated by an unknown input observer. The feasibility and validity of the proposed scheme were proven by simulation results.
