The plurality of vent outlets 3 is represented in Fig. 2 by six vent outlets 30, 31, 32, 33, 34, 35 with adjustable aperture and vent direction distributed at different locations in the cabin 23.
Four vent outlets 30, 31, 32, 33 are arranged in the front the cabin 3 of the vehicle 21. Two of the vent outlets 30, in the front are arranged on the left-hand side for providi the conditioned air to the passenger on the left front seat 24. Two of the vent outlets 32, 33 in the front are arrange on the right side for providing the conditioned air to the driver on the driver seat 25.
Two of the vent outlets 34, 35 are arranged in the central part of the cabin 3 and are directed towards the back seat 6.
The small arrows at the vent outlets 30, 31, 32, 33, 34, 35 indicate direction of the conditioned air flowing from the vent outlets 30, 31, 32, 33, 34, 35.
The controller 6 receives the occupancy information of the vehicle 21 from the occupancy sensor and the information about the current state - i.e. aperture and the vent direction - of the vent outlets 30, 31, 32, 33, 34, 35. Based on this information, the controller determines whether the current status of the vent outlets 30, 31, 32, 33, 34, 35 corresponds to the current occupancy situation of the vehicle 21. The controller adjusts the vent outlets by means of actua- tors 5 (not shown in Fig. 2) if it determines that the current status of the vent outlets 30, 31, 32, 33, 34, 35 does not correspond to the current occupancy state of the vehicle 21.
In the occupancy state of the vehicle 21 as shown in Fig. 2, all vent outlets 30, 31, 32, 33, 34, 35 are open. Thus, the conditioned air is targeted to all persons sitting in the vehicle 21.

The vent outlets 34 and 35 in the central part of the cabin 23 are adjusted by the controller 6 according to the occupancy situation is such way that the right vent outlet 35 arranged in the central part of the cabin 23 is open, while the left vent outlet 34 arranged in the central part of the cabin 23 is closed, as indicated by a cross on the vent outlet 34 in Fig. 3. Thus, the conditioned air flows from the vent outlet 35 towards the passenger sitting on the back seat 26. By closing the vent outlet 34, more conditioned air is available for purposely directing to the persons sitting in the vehicle 21. Fig. 4 shows a schematic top view of the vehicle in a third occupancy state.
In the occupancy state shown in Fig. 4, the both front seats 24, 25 are occupied, while the back seat 26 is not occupied.
On determining the occupancy state based on the information provided by the occupancy sensor 4, the controller 6 adjusts the vent outlets 30, 31, 32, 33, 34, 35 accordingly. In the adjusted state, shown in Fig. 4, the four vent outlets 30, 31, 32, 33 arranged in the front part of the cabin 23 are open. Thus, the passenger on the left front seat 24 and the driver on the right front seat 25 are provided with the conditioned air as shown by the arrows at the vent outlets 30, 31, 32, 33.
The vent outlets 34 and 35 arranged in the central part of the cabin 3 are closed, as indicated by crosses on the vent out- lets 34 and 35 in Fig. 4. Thus no targeted conditioned air is wasted on the back part of the cabin 23.
Fig. 5 shows a schematic top view of the vehicle in a fourth occupancy state.
In the occupancy state shown in Fig. 5, the passenger front seats 24, 26 are not occupied. On determining the occupancy state based on the information provided by the occupancy sensor 4, the controller 6 adjusts the vent outlets 30, 31, 32, 33, 34, 35 accordingly.
In the adjusted state, shown in Fig. 5, the two vent outlets 30, 31 arranged on the left-hand side in the front part of the cabin 23 and the two vent outlets 34, 35 in the central part of the cabin are closed, while the two vent outlets 32, 33 on the right-hand side in the front part of the cabin 23 are open .
Thus, the driver on the right front seat 25 is provided with the conditioned air as shown by the arrows .
By closing the vent outlets 30, 31, 34, 35 no targeted condi- tioned air is wasted on those locations in the cabin 23 where no passengers are present. Thus more conditioned air is available, which can be targeted to the driver.
Fig. 6 shows a schematic top view of the vehicle in a fifth occupancy state.
In the occupancy state shown in Fig. 6, the both front seats 24, 25 are occupied. The back seat 26 is occupied by one passenger who is sitting in the middle of the back seat 26.
