Patent ID: 8061459

Claim:
A traction control method for a tracked vehicle comprising: calculating a minimum turn radius of the tracked vehicle at which the tracked vehicle does not slip using a maximum coefficient of friction between tracks of the vehicle and ground; calculating a required track speed differential configured to turn the tracked vehicle at the minimum turn radius; determining if a commanded turn radius is less than the minimum turn radius; and limiting the track speed differential of the tracked vehicle by selectively transferring more power to at least one of a first track and a second track to achieve the required track speed differential if the commanded turn radius is less than the minimum turn radius such that the tracked vehicle does not slip; wherein said calculating a required track speed differential includes determining a track proportionality factor α and a vehicle proportionality factor β, and the vehicle proportionality factor β is calculated from the track proportionality factor α according to an equation β = ( 0.664 α - 0.212 ) 2 .
