Abstract: 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.

Abstract: A system for controlling a suspension of a vehicle includes a plurality of sensors, an anti-roll moment module configured to determine a front-to-total anti-roll moment distribution based on at least a first operating parameter of the vehicle, at least one suspension actuator, and a suspension control module configured to control the at least one suspension actuator based on the determined front-to-total anti-roll moment distribution. A method of producing an anti-roll moment distribution module for a vehicle includes determining understeer characteristics of the vehicle, determining a maximum lateral acceleration of the vehicle, adjusting the understeer characteristics based on the determined maximum lateral acceleration, determining reference understeer characteristics, determining a plurality of reference yaw rates and a plurality of feedforward contributions using a non-linear quasi-static model of the vehicle, storing the reference yaw rates in a first look-up table, and storing the feedforward contributions in a second look-up table.
