A Study of Novel Traction Control Method for Electric Motor Driven Vehicle 2009-26-0039
Electric-motor-driven vehicles have attractive performance attributes not only for environmental solutions but also for vehicle motion control. An electric motor offers significant advantages such as fast torque response, accurate estimation of torque output and the possibility of distributing motors independently in each wheel. These advantages effectively contribute to advanced motion control. In this study, two feedback controllers were constructed for skid prevention during vehicle acceleration. A model-following controller was used to consider the influence of back electromotive force and a slip ratio controller was used to consider the interaction between traction wheels.
