Abstract
A method for dynamically determining a mass of a vehicle including a propulsion system coupled to a drive wheel is described, and includes monitoring vehicle operating conditions, executing an event-based estimation method based upon the vehicle operating conditions to determine a first vehicle mass state, and executing a recursive estimation method based upon the vehicle operating conditions to determine a second vehicle mass state. A final vehicle mass is determined based upon the first and second vehicle mass states.
