    The suspension systems of vehicles are being actively researched to improve steering stability and ride comfort of vehicles. Among
    these, the active stabilizer system exhibits improved steering stability and ride comfort during the turning of a vehicle by controlling
    the vehicle body roll through actuators mounted on the front and rear stabilizer bars. This paper proposes an active stabilizer system
    of the electrohydraulic drive type, which addresses the disadvantages of the conventional hydraulic drive type whose active stabilizer
    system has poor ride comfort and causes excessive energy loss due to the system structure. In this study, the electrohydraulic actuator
    system model is designed, and the dynamic characteristics of the vehicle are analyzed with a simple proportional-integral-derivative
    (PID) controller for controlling the roll angle of the vehicle through the active stabilizer depending on the application of the designed
    system. The designed hydraulic model and system are evaluated based on the dynamic characteristics of a vehicle fitted with the active
    stabilizer of the electrohydraulic drive type and analyzed using the interface-analysis method between MATLAB!Simulink and CarSim.
    Furthermore, the results of the simulation are compared with those from the bench test to evaluate the performance.
