Definitions
- a method of controlling a fragrance diffuser in the passenger compartment of a motor vehicle A method of controlling a fragrance diffuser in the passenger compartment of a motor vehicle.
- the present invention relates to fragrance dispensing devices inside the passenger compartment of motor vehicles, and relates in particular to a method of controlling such diffusers. Background of the invention
- Fragrance dispensing devices are already known, which most often comprise a receptacle possibly provided with a lid or a similar closure element that the user maneuvers when he wishes to obtain an emission of perfumed air, this receptacle comprising suspension means at an appropriate point of the passenger compartment, where appropriate in front of an outlet port through which the air, hot or cold, supplied in this passenger compartment by a fan or by simple natural convection.
- the French application FR 2 867 424 describes such a diffuser provided with several cartridges in order to be able to diffuse, at the request of the occupants of the vehicle, several different fragrances.
- the user also has the opportunity to adjust the intensity of the smell of the scent felt in the passenger compartment, the area of diffusion of this perfume in the passenger compartment, the duration of the diffusion cycle or the diffusion intermittence duty cycle with respect to the complete duration of a cycle.
- the present invention therefore aims to improve the olfactory perception of the fragrance diffused by the user and to avoid any habituation reaction.
- the control method according to the invention takes into account the level of olfactory intensity of this fragrance in the determination of least one of these broadcast parameters.
- the odor intensity will be defined by the level of the power of a scent according to at least three criteria:
- the level of the power of a perfume is measurable either by physicochemical sensors, or by the quotation via a panel method.
- the olfactory intensity is no longer defined in relation to a feeling in the passenger compartment but by predefined values according to the three criteria defined above.
- this fragrance diffuser control method makes it possible to reduce the consumption of fragrances having a high level of olfactory intensity, such as jasmine.
- the diffusion parameter or parameters determined automatically according to the level of olfactory intensity of said fragrance are chosen from among the following parameters: the duration of the diffusion cycle of the fragrance, the diffusion duty cycle, the number of consecutive diffusion cycles; , the duration of the delay period that triggers once the number of cycles consecutive is reached and during which the diffusion of said fragrance ceases completely, and the flow of fragrance;
- the diffusion duty cycle is determined automatically according to the level of olfactory intensity of said fragrance
- the flow of fragrance is determined automatically according to the level of olfactory intensity of said fragrance
- said identification step is carried out using a database stored in memory which associates all the fragrances likely to be diffused by said diffuser to predefined levels of olfactory intensity;
- the number of predefined olfactory intensity levels is between 2 and 10, and preferably equal to 5;
- said method comprises, prior to said step of automatic determination of one or more diffusion parameters, a step of checking the temperature prevailing inside the passenger compartment, said automatic determination step being implemented only if said temperature is between a minimum value and a maximum value;
- said minimum temperature value is equal to 10 ° C and said maximum value is equal to 40 ° C .;
- said method comprises, before said step of automatic determination of one or more diffusion parameters, a step of checking the air flow delivered by the ventilation system of the passenger compartment of said vehicle, said automatic determination step not being implemented only if said airflow is greater than or equal to a threshold value.
- FIG. 1 shows a block diagram of a fragrance diffusion device in the passenger compartment of a motor vehicle, adapted to implement the method according to the invention
- FIG. 2 represents a flowchart of the method according to the invention.
- the diffusion device 1 comprises a fragrance diffuser 10 integrated into the ventilation system of a vehicle and comprising a housing for a removable and interchangeable cartridge 11 provided with three compartmentalized reservoirs A, B and C containing different fragrances.
- the diffuser 10 also comprises means 12 for recognizing the cartridge 11 to identify its exact reference, each reference corresponding to a specific arrangement of different fragrances.
- a first reference would contain the fragrances Muguet, Lavender and Jasmine; a second reference would contain Vanilla, Green Apple and Orange fragrances; And so on...
- each cartridge 11 is equipped with a perforated card which is decoded by a reader provided with several contactors. Depending on the location of the perforations on the card, the switches change position which causes the opening or closing of electrical circuits.
- the number of contactors is equal to three which is sufficient to allow the decoding of eight cartridge references.
- each of the reservoirs of a cartridge such as 11 has an orifice whose opening and closing are managed by a shutter mechanism such as a valve, a plug or a drawer for adjusting the flow rate D 0 of the flagrance.
- This shutter mechanism is controlled by an electromagnetic actuator 20, itself controlled by a control module 30 which determines the diffusion cycle of the fragrance according to the data received from the diffuser 10 and those transmitted by sensors 40 and 50 which respectively informs D airflow a r outputted from the vehicle ventilation system and the temperature T in t prevailing inside the passenger compartment of the same vehicle.
- the control module 30 comprises a computer 31 and a storage module 32 which comprises non-volatile memory of the EEPROM or FLASH type and the random access memory.
- the non-volatile memory stores a fragrance diffuser control process 10 which is implemented in this module 30 and whose flowchart is shown in FIG. 2.
- the diffuser 10 is connected to the onboard computer 60 of the vehicle to which it transmits the reference of the cartridge 11 inserted into the housing of this diffuser 10. According to this reference and a correspondence table stored in memory, the On-board computer 60 can thus determine the fragrance contained in each of the tanks of this cartridge 11.
- a setting mode allows the user to select, using a selector or a command button, the fragrance to be diffused among the fragrances that are proposed on the display screen 61 of the computer 60 and which correspond to those contained in the tanks of the cartridge 11.
- the control module 30 is also connected to the onboard computer 60.
- the latter indicates to the module 30 the type of fragrance selected by the user, while the module 30 transmits the information relating to the diffusion of the fragrance. so that they appear on the display screen 61.
- the fragrance diffuser 10 is independent of the ventilation system of the vehicle and comprises a self-contained ventilation module for diffusing the fragrance in the passenger compartment.
- the cartridge recognition means are different.
- the latter comprise a barcode or a smart card which is read by a specific reader that includes the broadcaster.
- the number of tanks that comprises the cartridge is different from three, for example between two and five.
- the control module checks whether the value transmitted by the D 40 of the air air flow sensor signal outputted from the aeration system of the passenger compartment of said vehicle is greater than or equal to a threshold value D min .
- the module 30 If the ventilation system is inactive or produces a D air air flow rate below this value D min threshold, the module 30 considers that the air flow is insufficient to ensure adequate diffusion of the fragrance in the passenger compartment and the process stops.
- the module 30 considers that the air flow D air is sufficient and the process continues with the step 200 in which the control module 30 checks whether the temperature T int prevailing inside the passenger compartment is between a minimum value T min (for example, set at 10 ° C) and a maximum value T max (for example, set at 40 ° C).
- T min for example, set at 10 ° C
- T max for example, set at 40 ° C
- control module 30 considers that the internal temperature of the passenger compartment T int is too high or too low to diffuse a fragrance and the process stops.
- step 300 the control module 30 identifies the level of olfactory intensity of the fragrance to be diffused which it becomes aware via the on-board computer. 60.
- the module 30 uses a database stored in memory that associates each type of fragrance that can be diffused by the diffuser 10 to a level of olfactory intensity I F predefined according to at least the following three criteria:
- the level of the power of a fragrance is measurable either by physicochemical sensors, or by the rating via a panel method.
- the number of predefined olfactory intensity levels is equal to 5, but this number may be different and for example between 2 and 10.
- the process will automatically determine all the diffusion parameters of the selected fragrance in the passenger compartment (step 400), namely:
- the duration of the diffusion cycle of the fragrance D CD preferably being between 30 and 300 seconds;
- the diffusion ratio CD R CD that is to say the ratio between the duration of diffusion of the fragrance on a cycle and the total duration of this cycle, this ratio is preferably between 20 and 100%;
- N C D the number of consecutive diffusion cycles N C D, preferably between 2 and 10;
- the flow rate D 0 of selected fragrance being preferably between 20 and 100%.
- the control module 30 will use a database stored in memory that associates each level of olfactory intensity with corresponding predefined values of these different parameters.
- the values of the ratio of diffusion R CD and flow D 0 will be much lower than those corresponding to the Vanilla fragrance whose level of olfactory intensity is much lower (for example, equal to 2/5).
- the process thus makes it possible to prevent the occurrence of a habit-forming reaction from the occupants of the vehicle, while reducing the consumption of fragrances with a high olfactory intensity.
- control module 30 As soon as the control module 30 has determined all the diffusion parameters, these are transmitted to the electromagnetic actuator 20 which controls the diffuser 10 (step 500).
- the method according to the invention does not include the step of comparing the air flow delivered by the ventilation system of the passenger compartment of said vehicle with a threshold value .
- the method can only handle the diffusion ratio R CD or the flow D 0 of the orifice of the reservoir containing the selected fragrance.
- control method may comprise additional steps.
- the latter may comprise a step of detecting the level of product remaining in each of the tanks of the cartridge by means of sensors integrated into this cartridge; and a step of sending a warning signal to the driver via the display screen of the on-board computer when the level of product remaining in one of the tanks reaches a predetermined threshold.
- the present invention is not limited to the embodiments described and shown, but encompasses any other embodiment.
