System and method for operating an HVAC system of a vehicle including an olfactory signal
In a method for operating a heating, ventilation, and air conditioning (HVAC) system of a vehicle, an input of an instruction of a user for the HVAC system is performed by means of a user interface. The HVAC system executes the input instruction. Furthermore, an olfactory signal is generated for the user by means of an olfactory device of the HVAC system as an input confirmation. Furthermore, a corresponding HVAC system for a vehicle is provided.
1. A method for operating a heating, ventilation, and air conditioning (HVAC) system of a vehicle, comprising:
setting a quantity and type of an olfactory substance to be emitted based on an HVAC function to be performed;
performing an input instruction for the HVAC system with a user interface;
executing the input instruction with the HVAC system;
generating an olfactory signal with an olfactory device of the HVAC system as an input confirmation;
generating the olfactory signal with the olfactory device as confirmation of an automatic activation and an automatic deactivation of a function of the HVAC system; and
adjusting a duration and an intensity of the olfactory signal in response to internal and external temperatures, incident sunshine, and ambient humidity.
2. The method as claimed in claim 1 , wherein at least one air duct of the HVAC system is used to generate the olfactory signal.
3. The method as claimed in claim 1 , wherein the olfactory device generates an odor based on the input instruction as the olfactory signal associated with the input instruction.
4. The method as claimed in claim 1 , wherein the olfactory device generates an odor, which is below a predetermined threshold of a conscious perception by a user, as the olfactory signal.
5. The method as claimed in claim 1 , wherein, in addition to the olfactory signal, at least one of an optical, acoustic, and tactile signal is generated as an input confirmation for the user.
6. The method as claimed in claim 1 , wherein a certain present state of the HVAC system triggers the olfactory signal for a user.
7. A heating, ventilation, and air conditioning (HVAC) system for a vehicle, comprising:
a user interface for receiving input instructions for the HVAC system;
a control device for executing the input instructions; and
an olfactory device configured to emit a plurality of olfactory signals, wherein the plurality of olfactory signals includes a first olfactory signal configured to be emitted as an input confirmation that corresponds to each of the input instructions and a second olfactory signal configured to be emitted upon completed execution of a function of the HVAC system, wherein each of the first and second olfactory signals is emitted in a preset quantity per unit of time and is a predetermined odor based on at least one of the input instruction by a user and a predefined state of the HVAC system, and wherein a duration is different for each of the first and second olfactory signals.
8. The system as claimed in claim 7 , further comprising:
at least one air duct of the HVAC system which is used to generate the plurality of olfactory signals.
9. The system as claimed in claim 7 , wherein the olfactory device is configured to emit an odor as the first olfactory signal indicative of the input instruction designated by the user and the second olfactory signal indicative the completed execution of the function of the HVAC system.
10. The system as claimed in claim 7 , wherein the olfactory device generates an odor, which is below a designated threshold of a conscious perception by the user, as the first olfactory signal representative of the input instruction.
11. The system as claimed in claim 7 , wherein, in addition to the plurality of olfactory signals, at least one of an optical, acoustic, and tactile signal is generated as an input confirmation for the user.
12. The system as claimed in claim 7 , wherein the olfactory device is configured to emit a third olfactory signal in response to a certain present state of the HVAC system.
13. A heating, ventilation, and air conditioning (HVAC) system for a vehicle, comprising:
a user interface for receiving an input instruction for the HVAC system;
a control device for executing the input instruction based on a predetermined user profile; and
an olfactory device configured to emit an olfactory signal, wherein the olfactory signal is configured to be emitted in response to each of the input instruction, a status of an external vehicle system, and an activation, deactivation, and or modification of the HVAC system, wherein a feedback olfactory signal is configured to be emitted upon execution of a function of the HVAC system, wherein the olfactory device includes settable outlet openings for metering a quantity of olfactory substances emitted as the olfactory signal and the feedback olfactory signal.
14. The system as claimed in claim 13 , wherein a type, a duration, and an intensity of the olfactory signal are individualized to a user based on the user profile.
15. The system as claimed in claim 13 , wherein the olfactory device is configured to emit an odor as the olfactory signal in response to a predefined event of the HVAC system.
16. The system as claimed in claim 13 , wherein the olfactory signal includes a first odor indicative of the input instruction for air conditioning and a second odor indicative of the input instruction for heat.
17. The system as claimed in claim 13 , wherein the olfactory device is configured to emit the olfactory signal in response to a predetermined desired state of the HVAC system.
