Presentation information generation device and presentation information generation method

A presentation information generation device comprising:

• air flow calculating circuitry to acquire ventilation equipment information indicating a state of ventilation equipment in a passenger car, and to output air flow information regarding an air flow in a car interior of the passenger car by using the ventilation equipment information;
• presentation information generating circuitry to generate and output an air flow image indicating a state of the air flow in the passenger car by using the air flow information output by the air flow calculating circuitry;
• and
• presentation information output circuitry to cause a display to present the air flow image output from the presentation information generating circuitry, wherein
• the ventilation equipment is disposed in such a way as to generate a plurality of air flows including at least an air flow between a ceiling central portion and a floor central portion in the car interior of the passenger car, and
• the air flow calculating circuitry outputs the air flow information by further referring to an air flow information database that stores in advance a relationship between a state in the passenger car and an air flow.
