Abstract
A system for a machine having an electric drive configuration is provided. The system includes a first motor associated with a first wheel, which provides torque to drive the first wheel, a second motor associated with a second wheel, which provides torque to drive the second wheel. The system further includes a controller configured to determine a rotational speed of the first wheel, determine a rotational speed of the second wheel, determine a steering angle of the machine, compare the rotational speeds of the first and second wheels, and adjust the torque to the first wheel if the rotational speed of the first wheel is less than the rotational speed of the second wheel.
