A Neighbourhood-Electric Vehicle Development With Individual Traction on Rear Wheels

The authors present a neighborhood electric vehicle simple traction control implementation in this paper. Two independent field-oriented controlled induction motors (IMs) mounted in the rear wheels are used to perform an electronic differential traction control. An equal torque traction control is performed using only the IM's currents and speed measurements in order to reproduce a mechanical differential behavior. To avoid uncontrolled wheel acceleration during equal torque control action, a basic self-blocking control is introduced. Energy recovery for batteries during vehicle braking is allowed by the traction system through the IM's regenerative braking. Standard industrial IMs are rewound to maintain the original motor power while operating on safe low voltage (28 V sub rms) and using standard DC-link 42 V. For these motor power requirements, two three-phase MosFet inverters are built. A single digital signal processor, TMS320F2812, is used to control the whole system. To validate the right traction control operation, experimental results for different vehicle maneuvers are presented.
