Abstract: A system includes a sensor and a controller. The sensor is configured to detect sliding of a wheel of a vehicle. The controller is configured to communicate with the sensor and a traction motor operatively connected to the wheel such that the traction motor selectively applies forces in at least one direction to the wheel during operation. The controller is further configured to direct the traction motor to apply a motoring slide reducing force to the wheel when the sensor detects sliding of the wheel resulting from a frictional braking force.

Abstract: A control method comprises determining wheel creep of a wheel operably coupled to a traction motor and limiting a rate of change of an excitation frequency applied to the traction motor to drive the wheel, based on the determined wheel creep. According to one aspect, the rate of change of the excitation frequency is limited if the wheel creep exceeds a wheel creep threshold.
