A neighborhood electric vehicle with electronic differential traction control

The implementation of a neighborhood electric vehicle with two independent wheel drives is presented. An electronic differential control is carry out by using two independent field-oriented controlled induction motors. Industrial standard induction motors were rewound to operate with low voltage (28 V
_rms
), while maintaining the original motor power. Two three-phase MOSFET inverters were built for these motor power requirements. The whole system is controlled using a single digital signal processor, TMS320F2812. Experimental results for different vehicle maneuvers are presented validating the right traction control operation.
