Hey guys,
I'm doing my final year project on an Electronic Drive System using 2 Brushless motors as hub-wheels for a rear-wheel drive. Just using steering angle and the accelerator to determine the differences in speeds for the drive wheels around a corner, etc.
Now I also wanted to implement some sort of Traction Control. I was thinking of maybe regulating the slip that each wheel could experience:
slip ratio = (Velocity(wheel) - Velocity(vehicle)) / Velocity(wheel)
So if I continously drive the motor at a constant speed, I was wondering whether there is a possibility that the wheel may at all slip? Logic tells me that if I give the motor some input, then it should more or less follow that reference speed. This is assuming that if the wheel rotates at, ie 2000rpm, then even if I lift the rear wheels off the ground (thus creating a slip scenario) then my wheels would continue to spin at 2000rpm?
So my question is, do I need to even take this slip into account?
Even more importantly, how do you design a limited-slip different for this?
Help much appreciated
