Abstract
A device and method for maintaining traction between wheels of a transporter and an underlying surface. The method has the steps of comparing acceleration of a wheel with a specified pre-set value, setting a slip condition flag based on the acceleration of the wheel, incrementally reducing the torque applied to the wheel based on the slip condition flag, determining a value of a dynamic characteristic of the wheel such as the inverse moment of inertia, and clearing the slip condition flag based on the value of that dynamic characteristic of the wheel.
