No matter whether the power source will be the electric batteries, or the IC engine/generator, or the fuel cell, etc., the power device for driving directly the tire/wheel of automobiles seems to shift from conventional IC engines to electric motors. The major characteristic difference between IC engines and electric motors, especially vector-controlled motors is rapidness of their torque response. That means the necessity of the traction control device. In this study, TRC which made the most of the superior feature of vector-controlled motors was successfully proposed.
