Abstract
One embodiment is a control system for a vehicle comprising a plurality of wheels, the control system comprising a master control unit (MCU); a plurality of traction systems corresponding to the wheels; and a plurality of rolling radius offset values stored in a memory device of the MCU and each corresponding to one of the wheels. The MCU determines for each wheel a command speed based on the rolling radius offset value for the wheel in combination with a tire diameter of the wheel, a steered angle of the vehicle, a traction pedal command, and vehicle geometry information, and provides the determined command speed for the wheel to the corresponding traction system, which controls a speed of the wheel based on the determined command speed received from the MCU.
