1. A method comprising:

  • obtaining an onboard-based input speed and an off-board-based input speed of a vehicle system;

    controlling a torque of at least a first axle of the vehicle system based at least in part on a throttle setting of the vehicle system, the onboard-based input speed, and the off-board-based input speed;

    determining an uncertainty parameter of the off-board-based input speed, the uncertainty parameter representative of a potential inaccuracy of the off-board-based input speed and of a range of potential speeds of the vehicle system; and

    modifying the off-board-based input speed using the onboard-based input speed responsive to determining that the onboard-based input speed is within the range of potential speeds represented by the uncertainty parameter.
