1. A method, comprising:

  • receiving at a data processing center sensor data from a first vehicle and a second vehicle;

    performing, at the data processing center, a mass estimation for the first vehicle and the second vehicle using the sensor data received from the first vehicle and the second vehicle respectively;

    determining that the first vehicle should assume a lead position and the second vehicle should assume a following position in a platoon based on the mass estimation of the first vehicle and the second vehicle respectively;

    coordinating the platoon between the first vehicle and the second vehicle, wherein the first vehicle assumes the lead position and the second vehicle assumes the following position in the platoon;

    arranging for the mass estimation of the first vehicle to be shared with the second vehicle;

    arranging for the first vehicle to share braking and torque commands generated on the first vehicle with the second vehicle;

    arranging for the second vehicle to scale the braking and torque commands received from the first vehicle while the first vehicle is leading the platoon, the scaling of the braking and torque commands based at least partially on a relative difference between the mass estimation of the two vehicles; and

    operating the second vehicle in accordance with the scaled braking and torque commands.
