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.

Abstract
Various applications for use of mass estimations of a vehicle, including to control operation of the vehicle, sharing the mass estimation with other vehicles and/or a Network Operations Center (NOC), organizing vehicles operating in a platoon and/or partially controlling the operation of one or more vehicles operating in a platoon based on the relative mass estimations between the platooning vehicles. When vehicles are operating in a platoon, the relative mass between a lead and a following vehicle may be used to scale torque and/or brake commands generated by the lead vehicle and sent to the following vehicle.

12. A method, comprising:
-
generating sensor data for a first vehicle; calculating a mass estimation for the first vehicle based on the generated sensor data; and sharing the calculated mass estimation for the first vehicle with one or more additional vehicle(s); organizing the first vehicle and one or more other vehicles to operate in a platoon; sharing braking and torque commands generated by the first vehicle with the one or more other vehicles; at the one or more other vehicles, scaling the braking and torque commands shared between the first vehicle and the one or more other vehicles based at least partially on the calculated mass estimation of the first vehicle; and operating the one or more other vehicles using the scaled braking and torque commands while operating in the platoon. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
