A system for validating velocities of components in a vehicle uses sensor measurements and mathematical relationships between the vehicle components to validate the velocities. A controller or controllers receive speed or velocity inputs and mathematically combine the velocities of more than one of the vehicle components. The velocities of at least one of the vehicle components is validated when the mathematical combination meets at least one predetermined criterion. The validated velocity or velocities are then communicated to at least one of the vehicle components.
