Abstract
Systems and methods provide accurate determinations of relevant vehicle mass that can take into account any load being carried and/or towed by a vehicle, such as an electric vehicle or hybrid vehicle. Systems and methods also provide accurate road load measurements that can take into account road gradient(s) and the impact of gravity. Accordingly, the dynamic nature of relevant vehicle mass and road load can be captured. Efforts to optimize operation and/or take preemptive action to provide more efficient performance, enhance the drive experience, etc. can be better achieved through the more accurate determinations of relevant vehicle mass and road load achieved by these systems and methods.
