It is difficult for the driver to handle the vehicles under low adhesive road surfaces. Benefited from the advantages of fast response and easy measurement to the motor torque, better traction performance can be achieved in Electric Vehicles (EVs). In the paper a novel traction controlstructure utilizing the adaptive driver's demanded slip ratio reference based on the road identification is proposed, where the driver's operation on the accelerator pedal is modeled in the equivalent form of the adaptive slip ratio according to different road surfaces. Compared with the other two structures with the torque selector inside control loop of the optimal slip ratio, the proposed method can acquire better dynamic performance while maintaining the driving safety. Furthermore, the driving comfort can be guaranteed benefited from the full utilization of the pedal range. Simulations are implemented to evaluate the effectiveness
