Abstract: This paper proposes the integration of three chassis control systems. In the first part, three chassis control systems including hydraulically interconnected suspension, torque vectoring system and active rear steering are introduced then these subsystems are evaluated by ramp steer and step steer manoeuvres; effectiveness and limits of subsystems are also reviewed. Then, two methods (optimal control and rule-based method) are proposed for integrated vehicle dynamics system. Both methods are evaluated with various manoeuvres to understand the advantages and disadvantages of each method.

Keywords: active steering; torque vectoring; hydraulically interconnected suspension; integrated vehicle dynamics control; vehicle dynamics; active chassis control system.
