Ghosh, J., Foulard, S., and Fietzek, R., "Vehicle Mass Estimation from CAN Data and Drivetrain Torque Observer," SAE Technical Paper 2017-01-1590, 2017, doi:10.4271/2017-01-1590.
A method for estimating the vehicle mass in real time is presented. Traditional mass estimation methods suffer due a lack of knowledge of the vehicle parameters, the road surface conditions and most importantly the effect of the vehicle transmission. To resolve these issues, a method independent of a vehicle model is utilized in conjunction with a drivetrain output torque observer to obtain the estimate of the vehicle mass. Simulations and experimental track tests indicate that the method is able to accurately estimate the vehicle mass with a relatively fast rate of convergence compared to traditional methods.
