Abstract  
The present paper aims to design an active vehicle system suspension by modification passive suspension into consideration the chassis is flexible to provide us the actual suspension image to make the best performance of the car and ride comfort. Creation of a State-Space half-car Model from a Finite Element, Model achieved by use MATLAB and Controlled by (LQR) Problems with its parameters Q and R which used in the determination of optimal car suspension systems design. The challenge is minimizing the chassis deflection; displacement and reduce the acceleration of suspension vibration. It is shown in our result that the model response to the Q and R-value is positive.
