Abstract

According to the evaluation method of riding comfort and handling safety of vehicle, the acceleration of the sprung mass, dynamic tyre load between wheels and road and dynamic deflection between the sprung mass and the unsprung mass are determined as the evaluation targets of suspension performance. Generalized adaptive control and LMS adaptive control are studied in two-DOF vehicle suspension model. The results show that the LMS adaptive control method has the better control for vehicle vibration. The simulation results show that LMS adaptive control algorithm is not only simple but also remarkably effective. It improves further that the active control suspension system can improve both the riding comfort and handling safety in various operation conditions, and it is foundation to make further approach to vehicle active suspension.
