Active roll control system offers better solution in improving the vehicle comfort and handling. There are various ways of active roll control system actuation like electrical, hydraulic and electro-hydraulic combination systems etc. For the current work, dual hydraulic actuator based active roll control mechanism is used. In this paper we have used integrated Model-In-Loop (MIL) based simulation approach is used to validate the active roll control system. Dual linear hydraulic actuators models and control logic for improving the roll dynamics of the vehicle is built using Matlab/Simulink. In IPG Car maker, a Model in Loop based tool the desired car characteristics and maneuver and road profiles are modeled and the Simulink model is integrated with car maker model for validating the performance in extreme cornering maneuvers, such as single and double lane change, single and double step steer. For these dynamic maneuvers the roll angle vs lateral acceleration is monitored and effectively maintained to the desired values. The proposed integrated approach offers numerous advantages in terms of cost and time involved in the physical testing and validation.
