APPLICATIONS FOR USING MASS ESTIMATIONS FOR VEHICLES
First Claim
Patent Images
1. A method for performing a mass estimation calculation for a vehicle, comprising:
- collecting sensor data indicative of one or more operational parameter(s) of the vehicle while operating;
generating a first mass estimation using a primary mass estimation algorithm over a long horizon period of time;
generating a second mass estimation using a secondary mass estimation algorithm over a short horizon period of time relative to the long horizon period of time;
comparing results of the first mass estimation and the second mass estimation; and
determining that the first mass estimation is valid based on the comparison.

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.

24. A method comprising:
-
operating a first vehicle as a lead vehicle and a second vehicle as a following vehicle in a platoon; providing a first mass estimation of the first vehicle to the second vehicle; scaling a command generated by the first vehicle and transmitted to the second vehicle, the command scaled based at least partially on the first mass estimation of the first vehicle relative to a second mass estimation of the second vehicle; and implementing the scaled command at the second vehicle. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33)
