Abstract
Performance evaluation of intelligent chassis controller such as ESC, CDC has been carried out using ECU-in-the-loop simulator. In the ECU-in-the-loop simulator, the real-time multibody vehicle dynamics model based on the subsystem synthesis method has been employed. In the real-time multibody vehicle model, suspension kinematics is fully considered by the linkage and joint connections. Thus, control force can be applied to mounting point and the suspension linkage, according to the suspension geometry. RT-LAB real-time solution and the Compact-RIO general purpose ECU (Electric Control Unit) are utilized to construct an ECU-in-the loop simulation environment. Fish-hook and Sine-with-dwell simulations have been carried out. Various combination of the ESC and the CDC have been carried out to investigate the performance of the intelligent chassis controller.
