In this paper a Four-Wheels-Drive (4WD) electric Vehicle (EV) controlled by Direct Torque Control DTC) is presented, where the electrical traction chain was well analyzed and studied from the nickel metal hydride (NIMH) battery, the buck boost to the mechanical load behavior. The speed of the four wheels is calculated independently during the turning with the electronic differential system computations which distributes torque and power to each inwheel motor according to the requirements, adapts the speed of each motor to the driving conditions. The basic idea of this work is to maintain the initial battery state of charge (SOC) equal to 70% and the prototype was tested in several topology conditions and under speed. Our electric vehicle direct torque control is simulated in MATLAB SIMULINK environment. 4WD Electric vehicle (EV) has demonstrated satisfactory results in all kind of roads constraints: straight, ramp, curved road and downhill. Results also indicate that this strategy can be successfully implemented into the traction drive of the modern 4WD electric vehicles.
