| Abstract | The paper presents the results of some experimental tests conducted on a passenger car equipped with changeable damping level shock absorbers in order to investigate the influence of adaptive damping level controller on vehicle dynamics during double lane change maneuver. The shock absorbers were semi-active dampers with a bypass proportional valve. The dampers were controlled by a prototype controller developed and programmed with Matlab/Simulink system and implemented on the controller rapid prototyping platform dSpace. The car was equipped with some sensors used by the controller and some used just to measure vehicle dynamics. Optical vehicle velocity sensors, vehicle roll and pitch rate gyroscopic sensors, vehicle lateral and longitudinal acceleration sensors, sprung and unsprung mass accelerations and suspensions deflection sensors were used. The steering angle and brake pedal travel sensors were also used. The prototyping board was the source of additional signals connected with control algorithm and calculated on-line by a real time computer during controller functioning. Several tests of double-lanechange maneuver were performed with various constant sets of damping level within the limits of available damper characteristic and some with adaptive controller actively changing damping level due to some chosen signals predicting vehicle dynamics. The results of some exemplary tests were presented to show the behavior of the car during this maneuver. A statistical analysis was performed to investigate the influence of various constant damping levels and adaptive damping level on vehicle dynamics before formulating conclusions at the end of the article. The obtained results show the level of improvement of vehicle dynamics with semi-active dampers controlled with adaptive controller taking into account some lateral vehicle dynamics aspects. |
