Abstract :
Two DC motors drive the two independent rear wheel of an electric vehicle with electric differential. The speed estimation of each wheel drive is based on the voltage equation which requires the voltage and armature current measures and a previous knowledge of the machine parameters. The current limitation and the speed control of the DC motors are determined by the result of a logical function, thus PI controllers are unnecessary. The overall control strategy is guaranteed by a single microcontroller, PIC18F452
