Description

Technical Field

[0001] Various aspects of this disclosure relate to apparatus and methods for regenerating air purification components of a vehicle's cabin air system. Background Technology

[0002] Vehicle cabin air systems typically include air purification components (such as filters) to remove contaminants, such as carbon monoxide, carbon dioxide, or nitrogen oxides, from the air supplied to the vehicle interior. These air purification components eventually become saturated and require replacement, which is inconvenient and wasteful for vehicle owners. Therefore, an alternative to replacement is the regeneration of these air purification component filters, which can be done, depending on the type of air purification component, for example, by heating it to a high temperature. However, regeneration requires consideration of various issues, such as the energy consumption for heating the air purification component and pollution caused by the regeneration process, for example, pollution caused by the release of adsorbed gases during the regeneration of the air purification component.

[0003] Therefore, a suitable solution is needed for regenerating air purification components. Summary of the Invention

[0004] Various embodiments relate to a method for regenerating an air purification component of a vehicle's cabin air system, the method comprising determining whether the vehicle is in an indoor or outdoor environment, and initiating an air purification component regeneration process for the air purification component in response to a positive determination that the vehicle is in an outdoor environment.

[0017] According to some embodiments, location-based data is used to determine whether a vehicle is in an indoor or outdoor environment.

[0018] According to some embodiments, the method includes initiating an air purification component regeneration process only when there is certainty that the vehicle is charging at a charging station.

[0044] The embodiments will be described in detail below.

[0045] Figure 1 A vehicle 100 with a cabin air system is shown.

[0046] The cabin air system may include one or more filters 101, a fan 102, and duct 103, which work together to provide and circulate air throughout the cabin of the vehicle 100. The filtration system of the cabin air system may be designed to remove contaminants, dust, and other harmful particles from the air, while also regulating temperature and humidity levels. Specifically, the cabin air system operates as a cabin air filtration system and can be considered as such. Similarly, the cabin air system can operate and be considered as an in-vehicle air filtration system. In some embodiments, the filter 101, fan 102, and duct 103 may be arranged in series. In some embodiments, the fan 102 may be arranged or configured to draw air from the cabin toward the filter 101; that is, the fan 102 may be configured as a suction device.

[0047] The cabin air system includes a controller 104 that controls its operation through various control actions, such as fan speed and the degree to which vents and air ducts are open. The controller 104 may, for example, measure interior air quality and execute corresponding control actions. Interior air quality can be measured using one or more sensors. The one or more sensors may include at least one hardware sensor, at least one software sensor, or a combination of at least one hardware and software sensor. In some embodiments, the one or more sensors may also include on-board sensors and / or remote sensors. Contaminant concentrations may optionally be calculated based on their correlation with other measurement parameters, for example, as virtual sensors.

[0048] Filter 101 may include one or more air purification components, particularly an absorber and / or adsorber. For example, the filter may include a solid material used as an adsorber and a liquid used as an absorber to remove both particulate matter and gases from the air.

[0049] The cabin air system filter 101 may include an air purification component that can absorb or adsorb compounds chemically, physically, or both. A common example is activated carbon. Another example is a moisture absorber, such as silica gel. The absorber may also be liquid or include liquid. Some absorbers absorb CO2, CO, NOx, and / or other harmful or, at high concentrations, gases. Air purification components (such as absorbers and / or adsorbers) require regeneration if they are to be reused, rather than being discarded and replaced with new air purification components when they are at full capacity.

[0050] According to various embodiments, when the vehicle is not in use, the vehicle's air purification components (such as absorbers and / or adsorbers) are regenerated, even if they may only be partially loaded. The air purification components can be regenerated by, but not limited to, heating the components. In particular, this can be done when the vehicle is ready for its next use, such as when an electric vehicle is charging. Regeneration during charging has the advantage that the power required to regenerate the purification components can be drawn from the charging power rather than the vehicle's internal battery. Regeneration (e.g., controlling the heater) can also be controlled by controller 104.

[0051] However, indoor regeneration can be harmful if ventilation is inadequate. For example, carbon dioxide levels in a garage could rise to harmful levels. Furthermore, agricultural vehicles may be exposed to pesticides that are absorbed by the cabin air system filters, which should not be regenerated indoors.

[0052] In view of the above, according to various embodiments, the process of controlling the regeneration of the air purification components of a vehicle may include the step of detecting the location of the vehicle 100 within or outside a geographic boundary, or by detecting the intersection of geographic boundaries between an indoor and an outdoor environment. The geographic boundary may be a physical and / or virtual boundary. For example, a geofence may be used to create one or more indoor / outdoor boundaries, and the location of the vehicle 100 within or outside the geofence will determine whether to perform regeneration of the air purification components. This decision can be further refined by detecting whether the indoor environment has sufficiently high ventilation and, in this case, performing regeneration even if the vehicle is indoors.

[0053] Figure 2 Flowchart 200 is shown, illustrating the regeneration control process or method for air purification components.

[0054] The control process is described with reference to the regeneration of the air purification components in a vehicle, but it is not limited to automobiles; it can also be applied to vehicles for heavy-duty, industrial, or agricultural applications, for example.

[0055] In some embodiments, the process may be performed by controller 104.

[0056] In step 201, check if the vehicle is turned off.

[0057] When a vehicle is detected to be off (i.e., it is definitively confirmed that the vehicle is off), it is determined in step 202 whether the vehicle is outdoors or indoors. This determination can be based on whether the vehicle is outdoors or indoors.

[0058] If the vehicle is outdoors, air purification component regeneration is performed at point 203, for example, if the air purification component is at least partially loaded. In some embodiments, determining whether the air purification component is partially loaded may include comparing the load with one or more predetermined thresholds.

[0059] The air purification component regeneration control process may optionally include detecting external levels of one or more contaminants. For example, one or more contaminants may be generated during air purification component regeneration, such as the release of adsorbed gases. The air purification component regeneration control process allows regeneration to begin or continue only when the external level is within acceptable predetermined limits.

[0060] In some embodiments, if it is determined that the vehicle is indoors, it can be further determined in step 204 whether the levels of one or more pollutants are higher than one or more predetermined thresholds. In some embodiments, the further determination can be performed continuously or at each predetermined time interval (e.g., every 10 seconds, 20 seconds, etc.).

[0061] In some embodiments, one or more contaminants in a vehicle may include, for example, external CO2 filtered through an air intake and / or a single activated carbon filter, or NH3, pesticides, or volatiles used for other applications.

[0062] Once, based on a comparison with one or more predetermined thresholds, the corresponding one or more determined (i.e., monitored) pollutant levels are no longer high, an air purification component regeneration process or procedure can be performed in 205. In some embodiments, the determination in 205 can be repeated, for example, with some set delay in 206.

[0063] Figure 3 Flowchart 300 illustrates whether an electric vehicle, including an electric motor, and / or a hybrid electric vehicle is located outdoors or indoors. Figure 2 Step 202.

[0064] Figure 3 The determination shown can be performed, for example, by controller 104, by a remote server, or by a combination of controller 104 and a remote server. In the case where the vehicle includes an electric motor, this example can be performed by… Figure 2 The corresponding controller 104 and / or server 202 in the air purification component regeneration control process 200 are executed.

[0065] In step 301, it is determined whether the vehicle is charging. If the vehicle is charging, then in step 302, the controller 104 / remote server attempts to obtain information from the appropriate charging station to determine whether the vehicle is indoors or outdoors. This information may include location information or information explicitly specifying whether the vehicle is indoors or outdoors, determined by the server based on the vehicle's location. If the charging station has such information, then that information is used in step 303 to determine whether the vehicle is indoors or outdoors. The location or position of the charging station can also be used as an indication of whether the vehicle is indoors or outdoors.

[0066] If the vehicle is not charging, the detection of whether the vehicle is indoors or outdoors can be performed in other ways at 304. For example, information about the vehicle's location can be obtained from a database 105 via wireless communication. The information about the vehicle's location can then be used to determine whether the vehicle is indoors or outdoors using geofencing (e.g., by means of a digital map). In some embodiments, one or more GPS-enabled devices in the vehicle or with a user (such as a driver) can be used to determine the vehicle's location.

[0067] Figure 4 The illustration illustrates the use of a digital map 400 for determining whether a vehicle is indoors or outdoors. For example, this could be based on the digital map 400, which indicates whether regeneration should be performed for various locations. The digital map 400 can be stored in the vehicle or accessed via radio communication. For instance, the controller 104 determines (e.g., via GPS or other suitable geolocation system) where the vehicle is located on the map, and thus can determine whether the vehicle is indoors or whether air purification component regeneration should not be performed for another reason.

[0068] exist Figure 4 In the example, the dashed area 401 represents a street area, so if it is determined that a vehicle is parked in the dashed area, a definite determination is made that the vehicle is outdoors. Similarly, an open-air parking lot (in...) can be indicated on map 400. Figure 4 (Shown by grid shading 402 in the map). Conversely, the white area 403 on map 400 corresponds to residential and commercial areas, and is therefore considered indoors unless otherwise specified.

[0069] Map 400 may also indicate areas, such as those in the shaded box 404, representing low-pollution areas. This corresponds to one or more areas where air component regeneration is not permitted, even though these areas are or contain outdoor areas, air component regeneration should still not be performed, for example, because low pollution should be maintained in such areas. Non-limiting examples of low-pollution areas include schools, hospitals, and high-density traffic areas. Controller 104 may take this into account, and may also consider situations where regeneration should be performed while driving.

[0070] In one embodiment, the location of an electric (or hybrid) vehicle (e.g., its charger) can be used to obtain information, for example, from a reference database, whether it is indoors or outdoors, or (e.g., if indoors) in a high-ventilation or low-ventilation area. The vehicle's location can be indicated by, but is not limited to, one or more coordinates. Such coordinates may include GPS coordinates. As mentioned above, location information can be transmitted to the vehicle (e.g., to controller 104) via a charging cable or wirelessly. For example, location information can be wirelessly transmitted to the vehicle via a phone app used to purchase charging and connected to controller 104. In another embodiment, information about whether the vehicle is indoors or outdoors can be transmitted directly, rather than depending on the vehicle's location.

[0071] In addition, in the case of electric (or hybrid) vehicles, the air purification component regeneration control process may include checking the battery charge before and / or simultaneously with regeneration, as the battery should not be depleted to a degree that compromises vehicle operability.

[0072] Therefore, for example, after determining that the vehicle is outdoors (or even indoors, the pollution level is low enough to perform regeneration), check whether the battery charge is sufficient (e.g., above a predetermined charging threshold), and if so, perform regeneration.

[0073] In summary, according to various embodiments, a method is provided as follows: Figure 5 The method is illustrated in the figure.

[0074] Figure 5 A flowchart 500 illustrates a method for regenerating an air purification component of a vehicle's cabin air system. The purification component may include an absorber and / or an adsorber. This method may, in particular, be an air purification component regeneration control process separate from the actual regeneration process. Method 500 may be implemented in a controller or server. In some embodiments, the controller may be an onboard controller of the vehicle 100, such as controller 104.

[0075] At point 501, it is determined whether the vehicle is in an indoor or outdoor environment. This determination can be based on the vehicle's location obtained via one or more sensors.

[0076] At point 502, in response to the confirmed presence of the vehicle in the outdoor environment, the air purification component regeneration process (i.e., the regeneration of the air purification component) is initiated.

[0077] According to various embodiments, when the vehicle is not in use, even if only partially loaded, the vehicle's air purification components (e.g., adsorbers and / or absorbers) are regenerated. For example, the air purification components can be fully regenerated to prepare the vehicle for the next journey, making the cabin air system ready for the next use. This is particularly beneficial for electric vehicles when they are charging, as the power to regenerate the air purification components can be drawn from the charging power rather than the vehicle's internal battery. However, if ventilation is insufficient, indoor regeneration can be harmful; for example, the CO2 level in the garage may increase to harmful levels. Furthermore, agricultural vehicles may be exposed to pesticides that can be absorbed by the cabin air filter, which should not be regenerated indoors. Therefore, according to various embodiments, as referenced... Figure 5 The described process for controlled regeneration includes a step of detecting whether the vehicle is indoors or outdoors (e.g., by using a geofence). If the vehicle is indoors, the process may further include detecting whether the indoor location has sufficiently high ventilation (and in this case, regeneration is performed even though the vehicle is indoors).

[0078] The methods described herein can be performed, and the various processing or computing units, devices, and computing entities described herein can be implemented by one or more circuits.
