SYSTEM AND METHOD FOR TRACTION CONTROL IN A WORK VEHICLE WITH AN ELECTRIC INFINITELY VARIABLE TRANSMISSION USING WHEEL SPEED

A work vehicle includes an engine and a transmission assembly having a variator, a gear arrangement, and an electric machine operably connected to provide rotational power to the variator. The transmission assembly selectively transfers power from one or both of the engine and the electric machine to an output shaft to drive ground engaging elements of the work vehicle. A traction control unit controls a speed or torque output of the electric machine to provide traction control, with the traction control unit operating to receive inputs on a predicted ground engaging element speed and an actual ground engaging element speed, compare the predicted ground engaging element speed to the actual ground engaging element speed and, when the predicted ground engaging element speed is less than the actual ground engaging element speed by a threshold amount, reduce the speed or torque output of the electric machine, thereby providing traction control.
