When the driver's posture is maintained during prolonged driving, a burden concentrates on the specific part and the driving fatigue is increased. We propose the air cell lumber support device that changes the lumbar posture periodically to reduce the driving fatigue increase for long distance driving. By using a driving simulator, the objective fatigue evaluation was measured based on the finger plethysmogram with or without our proposed device. From the results of the objective evaluations, a significant difference between using and not using the device was shown. Therefore, the effectiveness of our proposed device for the reduction of the driver fatigue increase has been verified.
