Key Findings in This Report

• A novel switching control strategy balances ride comfort and handling stability in full-car suspension systems. • The 14-DOF full-car model is simplified to three 2-DOF models (vertical, pitch, roll), simplifying controller design. • The proposed rollover risk indicator enables effective multi-modal switching between comfort and stability control. • Experimental results show significant reductions in vertical, roll, and pitch accelerations (up to 14.13%) and rollover risk metrics (up to 29.96%).
