Abstract
Official abstract text for this publication.
A method of producing an anti-roll moment distribution module for a vehicle comprises determining understeer characteristics of the vehicle, determining a maximum lateral acceleration of the vehicle, adjusting understeer characteristics of the vehicle based on the maximum lateral acceleration, determining reference understeer characteristics, determining a plurality of reference yaw rates based on (i) the maximum lateral acceleration and (ii) the reference understeer characteristics using a non-linear quasi static vehicle model, storing the plurality of reference yaw rates in a first look up table in the anti-roll moment distribution module, determining a plurality of feedforward contributions using the non-linear quasi static model of the vehicle. Each feedforward contribution of the plurality of feedforward contributions can be used to determine a front to total anti-roll moment distribution for the vehicle. The plurality of feedforward contributions are stored in a second look up table in the anti-roll moment distribution module.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method of producing an anti-roll moment distribution module for a vehicle, comprising: determining understeer characteristics of the vehicle; determining a maximum lateral acceleration of the vehicle; adjusting the understeer characteristics of the vehicle based on the determined maximum lateral acceleration; determining reference understeer characteristics; determining a plurality of reference yaw rates based on (i) the maximum lateral acceleration and (ii) the reference understeer characteristics using a non-linear quasi-static model of the vehicle; storing the plurality of reference yaw rates in a first look-up table in the anti-roll moment distribution module; determining a plurality of feedforward contributions using the non-linear quasi-static model of the vehicle, wherein each feedforward contribution of the plurality of feedforward contributions can be used to determine a front-to-total anti-roll moment distribution for the vehicle; and storing the plurality of feedforward contributions in a second look-up table in the anti-roll moment distribution module. 2 . The method of claim 1 , wherein the non-linear quasi-static model of the vehicle includes a set of equations and inequalities, and wherein determining the understeer characteristics includes: starting to solve the set of equations and inequalities using (i) increasing lateral acceleration values and (ii) constant velocity values, and stopping in response to being unable to find a valid solution to the set of equations and inequalities. 3 . The method of claim 1 , wherein determining the maximum lateral acceleration of the vehicle includes performing a minimization procedure on a cost function. 4 . The method of claim 1 , wherein determining the plurality of reference yaw rates and determining the plurality of feedforward contributions includes solving the set of equations and inequalities without using forward time integration.
