ABSTRACT:
A system and method for determining vehicle CG height and mass in real-time. The method includes selecting a set of vehicle parameters to be considered that includes the vehicle mass and the center of gravity height of the vehicle. Frequency responses are generated using the dynamic model and a plurality of different values for the selected vehicle parameters. During vehicle operation, frequency responses are calculated from a measured vehicle lateral acceleration to a roll angle and/or a roll rate of the vehicle. The generated frequency responses and the calculated frequency responses are compared to determine which of the generated frequency responses more closely matches the calculated frequency responses. The generated frequency responses that most closely match the calculated frequency responses are used to determine the center of gravity height and the vehicle mass from the values for the vehicle parameters.
