Description

[0001] This application is a divisional application of a patent application entitled "A Vehicle Odor Emission Device and Method Based on Electronic Maps", the original application was filed on August 3, 2022, application number 202210927507.6. Technical Field

[0002] This invention belongs to the field of car fragrance technology, and particularly relates to a method, system and device for emitting car odors. Background Technology

[0003] In recent years, with the continuous development of transportation infrastructure, road conditions have improved significantly, and the number of drivers has increased year by year. However, due to heavy driving loads and long, straight sections of road, drivers are prone to fatigue. Driver fatigue, caused by a decline in psychological and physiological functions, leads to dangerous behaviors where drivers are unable to obtain or process necessary information for safe driving, and is a major cause of traffic accidents. Currently, drivers lack effective means to cope with driver fatigue on the road. Most rely on external interventions, such as talking to others to alleviate fatigue or stopping to rest. However, in actual driving situations, drivers often find it difficult to stop and rest for various reasons. Perfume and other stimulating scents have long been considered effective in enhancing driver alertness and alleviating driver fatigue.

[0004] Current car air fresheners consist of a perfume bottle with a perfume chamber and vents to release the fragrance. However, this method means the fragrance is always present and cannot be adjusted in real-time to suit specific road conditions, such as long, straight stretches of road, which can cause driver fatigue and thus reduce driver alertness. Summary of the Invention

[0005] In response, the present invention provides a method, system and device for releasing vehicle odors, which releases perfume at appropriate times to relieve driving fatigue and improve safety during long-distance driving.

[0006] To achieve the above objectives, the present invention adopts the following technical solution.

[0007] A method for emitting odors in a vehicle includes the following steps: The system acquires road parameters and the user's fragrance concentration preference. The road parameters are obtained by connecting with the in-vehicle map application, including the road geometry, road curve radius, special road locations, traffic volume, and vehicle travel duration. Based on road parameters and users' fragrance concentration preferences, determine the specific location, time, concentration, and duration of fragrance release; A control signal is generated based on the specific location, time, concentration, and duration of perfume release to release the perfume in real time.

[0008] Optionally, the vehicle odor emission method further includes the following steps: Users can adjust the specific location, time, concentration, duration of release, and whether to enable automatic release function of the perfume at any time according to their personal habits.

Detailed Implementation

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here. Specific Implementation Example 1 like Figure 1 As shown, this embodiment provides a method for emitting odors in a vehicle, including the following steps S1 to S3.

[0021] S1. Obtain road parameters and user perfume concentration preferences.

[0022] Step S1 includes obtaining road parameters such as road geometry, road curve radius, special road locations, traffic volume, and vehicle travel duration through an electronic map, as well as obtaining the user's fragrance concentration preference. These road parameters are obtained by connecting with an in-vehicle map application.

[0023] S2. Based on road parameters and the user's fragrance concentration preference, determine the specific location, time, concentration, and duration of fragrance release; S3. Generate a control signal based on the specific location, time, concentration, and duration of perfume release to release the perfume in real time.

[0024] In some examples, the vehicle odor emission method further includes the following step S4: S4. Users can adjust the specific location, time, concentration, duration of release, and whether to enable automatic release function of the perfume at any time according to their personal habits. Specific Implementation Example 2 like Figure 2 As shown, this embodiment provides a vehicle-mounted odor emission system, including the following functional modules: The acquisition module is used to acquire road parameters and the user's fragrance concentration preference; the road parameters are acquired by connecting with the in-vehicle map application, including the road geometry, road curve radius, special road locations, traffic volume, and vehicle running duration; The calculation module is used to determine the specific location, time, concentration, and duration of fragrance release based on road parameters and the user's fragrance concentration preference. The automatic control module generates control signals based on the specific location, time, concentration, and duration of perfume release to release the perfume in real time.

[0026] The acquisition module, calculation module, and automatic control module are connected sequentially. The automatic control module establishes an automatic control device consisting of a host, transmission interface, industrial Ethernet switch, transmission cables, sensors, and other equipment, which is connected in real time to the vehicle's electronic map to control the release of perfume at a specific location.

[0027] In some examples, the vehicle-mounted odor emission system also includes the following functional modules: The user adjustment module, connected to the automatic control module, is used to adjust the specific location, time, concentration, continuous release time, and whether to activate the automatic release function of the perfume at any time according to the user's personal habits. The control signals generated by the module are also sent to the automatic control module. Specific Implementation Example 3 like Figure 3 As shown, this embodiment provides a vehicle-mounted odor emission device, including the following components: An electronic map acquisition module S100 can connect with map apps currently on the market to obtain road geometry, road curve radius, special road locations, traffic volume, and vehicle travel duration through electronic maps. A perfume box loading and unloading device S200 can put different scented perfumes into an automatic release device; A manual adjustment device S300 allows manual adjustment of the specific location, time, concentration, duration of release, and release switch of the perfume. A display device S400 can display the current location and perfume concentration in real time; An automatic release device S500 includes an automatically adjustable release hole or release net.

[0029] The host is used to execute the vehicle odor emission method, and the control signal generated therefrom is used to control the automatic release device S500 to release perfume in real time.

[0030] A further optimized solution involves, for example, based on the acquisition module's detection that drivers are highly susceptible to fatigue in long tunnels. Using the calculation and user adjustment modules, the specific location for releasing the perfume is determined to be the middle section of the tunnel, along with the perfume concentration and release duration. Based on the results determined by the calculation and user adjustment modules, the automatic release device S500, according to the control signal output by the automatic control module, releases the perfume intermittently after the vehicle reaches the middle section of the tunnel to stimulate the driver. Once the electronic map detects that the vehicle has left the long tunnel, the automatic perfume release device S500 shuts off.

[0031] Currently, the field of car air fresheners lacks a device capable of dispensing fragrances of varying concentrations in real time based on road conditions. This invention effectively monitors road conditions and releases fragrance at appropriate times according to pre-set environmental settings, thereby alleviating driver fatigue and improving safety during long drives.

[0032] Furthermore, in existing technologies, a perfume bottle can generally only hold one type of perfume. If a new perfume bottle needs to be purchased, it is necessary to change the perfume, resulting in waste. This invention, by incorporating a perfume box loading and unloading device S200, allows different scents of perfume to be placed into an automatic release device S500, thus avoiding the problem of perfume bottle waste.

[0033] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
