Abstract

A method and apparatus is disclosed for recursively estimating vehicle mass and/or aerodynamic coefficient of a moving vehicle. The vehicle speed and push force data are collected and a segment of qualified data is then selected from the collected data. Newton's second law is integrated to express vehicle mass and/or aerodynamic coefficient in terms of vehicle push force and vehicle speed. This expression is then used in a recursive analysis of the qualified data segment to determine an estimated vehicle mass and/or aerodynamic coefficient.
