Rolling parameter e.g. mass, estimating method for e.g. commercial vehicle, involves utilizing Kalman filter for estimating parameter using observation model, where filter is integrated to dynamic parameter evaluation model

摘要

The method involves measuring angular displacements of a rotating body during rolling, and utilizing a Kalman filter for estimating a parameter using an observation model (Mo) constructed based on a function between the parameter and the angular displacements, where the filter is integrated to a dynamic model (Md) of parameter evaluation. The model (Mo) is constructed based on a function between steering angle of the wheel and the displacements of the body of a stop on which the wheel is mounted, where the model (Mo) utilizes a linear function between the parameter and the displacements. An independent claim is also included for an assembly comprising a bump stop.
