The purpose of this study is to reduce the pain on a patient riding, in an ambulance bed. The active controlled pendulum type bed is being proposed to prevent the patient swaying on the bed as the vehicle turns around a corner and surging as the vehicle increases or decreases the speed. The bed system was designed to provide the passive safety, the robustness of the controller and the prevention of carsickness. A control system that enables the bed to roll and pitch was developed with the use of optimal control theory. A one-half scale model of the active controlled pendulum type bed was produced and loaded on a pickup truck. Then, control experiments were conducted to confirm the effectiveness of the bed system. The following results were noted: (1) The acceleration on the bed plane is less than one-fifth of the acceleration affecting the vehicle. (2) There is no delay as the acceleration changes by the active control. (3) The robustness for the moment of inertia of the patient was confirmed by the control experiment with 30 kg sandbag representing a patient on the bed.
