Claims (25)

Claims
1. A vehicle system for use in a vehicle, the vehicle system including an airflow system and a vehicle cabin defined, at least in part, by an upper cabin surface and a lower cabin surface, the airflow system being configured to condition air in the vehicle cabin and comprising: at least one upper air vent disposed in the upper cabin surface and at least one lower air vent disposed in the lower cabin surface; an airflow apparatus configured to direct an airflow through the at least one lower air vent and the at least one upper air vent; and a control system comprising one or more controllers configured to control the airflow through the at least one lower air vent and the at least one upper air vent.
2. The vehicle system as claimed in claim 1 , comprising a first airflow apparatus configured to direct a first airflow through at least one upper air vent in the upper cabin surface, and a second airflow apparatus configured to direct an airflow through at least one lower air vent in the lower cabin surface.
3. The vehicle system as claimed in claim 2, wherein the first airflow apparatus is configured to direct an airflow which is at a lower temperature than an airflow directed by the second airflow apparatus.
4. The vehicle system as claimed in claim 2, wherein the first airflow apparatus is configured to direct an airflow which is at a higher temperature than an airflow directed by the second airflow apparatus.
5. The vehicle system as claimed in any of claims 2 to 4, wherein the first airflow apparatus comprises an air conditioning unit.
6. The vehicle system as claimed in any of claims 2 to 5, wherein the second airflow apparatus comprises a heater.
7. The vehicle system as claimed in any of claims 2 to 6, wherein the first airflow apparatus comprises a first pump configured to direct a first airflow to at least one upper air vent in the upper cabin surface, and the second airflow apparatus comprises a second pump configured to direct an airflow to at least one lower air vent in the lower cabin surface.
8. The vehicle system as claimed in any of claims 2 to 7, wherein the first airflow apparatus is operable to provide suction that draws air into at least one upper air vent.
9. The vehicle system as claimed in any of claims 2 to 8, wherein the second airflow apparatus is operable to provide suction that draws air into at least one lower air vent.
10. The vehicle system as claimed in any of claims 1 to 9, wherein the at least one upper air vent and the at least one lower air vent are in vertical alignment with one another.
1 1. The vehicle system as claimed in any of claims 1 to 10, comprising an array of upper air vents disposed in the upper cabin surface.
12. The vehicle system as claimed in any of claims 1 to 1 1 , comprising an array of lower air vents disposed in the lower cabin surface.
13. The vehicle system as claimed in any of claims 1 to 12, wherein the vehicle cabin has a seat, the seat is moveable into a plurality of positions, and wherein the one or more controllers are configured to receive a seat signal relating to at least one of: (i) whether or not the seat is occupied, and (ii) the position of the seat, the one or more controllers being configured to generate a control signal to control the airflow apparatus in response to the seat signal.
14. The vehicle system as claimed in claim 13, wherein the seat is moveable to each of the plurality of positions by any one or more of: longitudinal movement; lateral movement; rotational movement; reclining movement; and folding movement.
15. The vehicle system as claimed in claim 13 or claim 14, wherein the control signal is configured to adjust automatically a status of one or more of the air vents in response to the seat signal .

A vehicle comprising the vehicle system as claimed in any of claims 1 to 19 and/or the control system of claim 20.
A method of controlling airflow through at least one lower air vent in a lower surface of a vehicle cabin and at least one upper air vent in an upper surface of the vehicle cabin, the method comprising: receiving a temperature demand signal indicative of a desired temperature for the vehicle cabin; receiving a temperature signal indicative of a temperature in the vehicle cabin; comparing the temperature signal with the temperature demand signal; and generating a control signal arranged to operate airflow apparatus to direct an airflow through at least one of the at least one upper air vent and the at least one lower air vent in dependence on the comparison between the temperature signal with the temperature demand signal.
The method as claimed in claim 22, comprising directing an airflow through the at least one upper air vent into the cabin if the temperature signal exceeds the temperature demand signal, and directing an airflow through the at least one lower air vent into the cabin if the temperature demand signal exceeds the temperature signal.
24. The method as claimed in claim 23, comprising directing an airflow out of the cabin through the at least one upper air vent if the temperature demand signal exceeds the temperature signal, and directing an airflow out of the cabin through the at least one lower air vent if the temperature signal exceeds the temperature demand signal.
