Vibration suppression strategy with model baaed command shaping

—Application to passenger car powertrain—

抄録

Speed feedback into driving force is an effective measure to add damping for motion control systems with no damping element, while effect of the feedback is decreased for systems with larger delay. A passenger car powertrain system is prone to be oscillatory and engine torque has structural dead time. An engine torque control algorithm that generates engine torque command from an accelerator operation to reduce vehicle longitudinal vibration without deteriorating acceleration using an online vibration model is developed. Numerical simulations and experiments show effectiveness of the proposed method.
