Electric vehicles (EVs) speed and torque control undergo different road constraints is very difficult using classi cal control methods. To overcome this problem a comparative studies between two control methods is proposed, the first one is space vector modulation technique based direct torque control (DTC-SVM) and the second one is the direct torque control proposed. Acceleration, steering and speed reference computations are ensured by the electronic differential, this driving process permit to steer each driving wheels at any curve separately. The two proposed control methods constitute an efficient driving force estimations, the SVM-DTC is characterized with less torque ripple oscillations for this reason, the hysteresis controller is substituted by PI controller and switch table is replace with space vector modulation. Our double driven electric vehicle is simulated in Matlab SIMULINK environment. The electric vehicle was tested in different constraints road: straight, slope, inverse slope and curved roads, the present electric propulsion system results present satisfactory.
