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.

Abstract: A control system and method is disclosed for controlling an active suspension and a leveling system for a motor vehicle. The control system may use estimator, controller and management modules. The estimator module processes measured signals obtained from various components and sensors of the vehicle relating to modal displacements, velocities and accelerations, and calculates derived signals which are used as inputs to the controller module. The controller module calculates the desired damper force for each active damper based on motions of the vehicle body and wheels. The management module translates the desired active damper force into an appropriate set of control signals to control each active damper. These operations are performed for each active damper of the vehicle to control each damper in real time.
