PROBLEM TO BE SOLVED: To reduce dyspnea of a subject due to the timing of switching between exhalation and inspiration not being met when the subject's psychosomatic state is changed by inducing the timing of breathing. SOLUTION: A rhythm determination unit 205 determines a target respiratory rhythm for changing the mental and physical condition of the driver to a target mental and physical condition, and a driver breathes in accordance with the target respiratory rhythm. The respiratory guidance control unit 206 that controls the respiratory guidance device 22 that stimulates the sensory organs to induce breathing is provided, and the rhythm determination unit 205 sets an expiratory period for exhaling and an inspiratory period for inhaling as target respiratory rhythms. In addition, during the expiratory period and the inspiratory period, and between the inspiratory period and the expiratory period, a grace period that is a switching period between expiratory and inspiratory that may perform either expiratory or inspiratory is determined, and respiratory induction control is performed. The unit 206 stimulates the driver's sensory organs in a manner in which the expiration period, the inspiration period, and the grace period can be distinguished from each other.
