System and method for controlling an axle of a vehicle

A method for a vehicle including an axle connected to wheels, wherein the axle is rotatable by a propulsion subsystem to propel the vehicle along a route, wherein the wheels are rotatable by the axle to propel the vehicle along the route, the method comprising:

• calculating, by a controller including one or more processors, a wheel size of at least one of the wheels of the vehicle during operation of the vehicle during a trip;
• determining, by the controller, if the wheel size is below a first threshold size;
• communicating, by the controller, a first message associated with the wheel size to a first off-board device in response to the wheel size being calculated to be below the first threshold size;
• and
• controlling, by the controller, the axle based on an off-board-based input speed, an onboard-based input speed, and the wheel size being below the threshold size.

A system for a vehicle including an axle connected to wheels, wherein the axle is rotatable by a propulsion subsystem to propel the vehicle along a route, wherein the wheels are rotatable by the axle to propel the vehicle along the route, the system comprising:

• at least one sensor on-board the vehicle configured to sense at least one operational parameter of the vehicle;
• one or more processors on-board the vehicle and in communication with the at least one sensor being configured to:
• determine a wheel size of at least one of the wheels of the vehicle while the vehicle is operating based at least in part on the at least one operational parameter;
• communicate a first message relating to the wheel size when the wheel size reaches a first threshold size;
• and
• control the axle based on an off-board-based input speed, an onboard-based input speed, and the wheel size being below the first threshold size or a second threshold size that is a smaller size than the first threshold size.
