Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more specifically, to a method, device, control equipment, and vehicle for indicating a vehicle-mounted hot / cold box. Background Technology

[0002] In-vehicle refrigerators and warmers have become widely used with the increasing popularity of electric vehicles, for storing food or medicine in vehicles. These refrigerators operate on an on-demand basis; if users forget items after getting out of the vehicle, food can easily spoil or medicines can become ineffective, resulting in waste, pollution of the vehicle's interior, and potentially impacting the user's health. Therefore, a smart reminder function for left-behind items is of significant practical value, and how to implement such a function is a pressing technical problem that needs to be solved. Summary of the Invention

[0003] This application addresses the shortcomings of the prior art by providing a method, device, control equipment, and vehicle for indicating the status of an in-vehicle heated / cooled box, thereby resolving the problems existing in the prior art.

[0004] The technical solution adopted in the embodiments of this application is as follows: In a first aspect, embodiments of this application provide a method for alerting users of an in-vehicle refrigerator / heater, including: Monitor whether the target vehicle containing the vehicle-mounted cooling / heating box is in a parked state; If the target vehicle is in a parked state, then the parking location type of the target vehicle, the operating status of the vehicle-mounted refrigerator / warmer box, and the door opening / closing behavior of the vehicle-mounted refrigerator / warmer box are obtained; the parking location type is a high-frequency parking location, a low-frequency parking location, or a temporary parking location; Based on the parking location type, the operating status of the vehicle-mounted refrigerator / warmer, and the door opening / closing behavior, determine the current reminder scenario of the vehicle-mounted refrigerator / warmer; The system employs a reminder strategy corresponding to the current reminder scenario of the vehicle-mounted refrigerator / warmer to send a reminder message to the user indicating that items have been left behind.

[0005] In one embodiment, before monitoring whether the target vehicle containing the on-board refrigerator / heater is in a parked state, the method further includes: During a single vehicle trip, determine whether the cumulative running time of the on-board cooling / heating box is greater than or equal to a preset time threshold. The monitoring of whether the target vehicle containing the vehicle-mounted cooling / heating box is in a parked state includes: If the cumulative runtime is greater than or equal to the preset duration threshold, then it is monitored whether the target vehicle where the vehicle-mounted cooling / heating box is located is in a parked state.

[0006] In one embodiment, obtaining the parking location type of the target vehicle, the operating status of the onboard refrigerator / warmer, and the door opening / closing behavior of the onboard refrigerator / warmer includes: Obtain the parking location of the target vehicle, and determine the type of parking location for the target vehicle during this trip based on the parking location; The operating status of the vehicle-mounted cooling and heating box is obtained during a first time period, which is the period from when the target vehicle enters the parking state to when the driver's side door is opened. The door opening and closing behavior of the vehicle-mounted refrigerator / heater box during a second time period is obtained, where the second time period is the time from the start of the vehicle-mounted refrigerator / heater box to the opening of the driver's side door; The step of determining the current alert scenario for the vehicle-mounted refrigerator / warmer based on the parking location type, the operating status of the refrigerator / warmer, and the door opening / closing behavior includes: Based on the parking location type, the operating status during the first time period, and the door opening and closing behavior during the second time period, the current reminder scenario of the vehicle-mounted refrigerator / warmer is determined.

[0007] In one embodiment, the method of determining the parking location type of the target vehicle in this trip based on the parking location includes at least one of the following methods: If the navigation function is not enabled during this trip, and the current parking time period is within the first statistical period, and the number of times the target vehicle has parked at the parking location in the past first statistical period is greater than or equal to the first threshold, then the parking location type of the target vehicle in this trip is determined to be a high-frequency parking location. When the navigation function is enabled for this trip, and the parking location is a preset frequently used location pre-entered in the navigation application, the parking location type of the target vehicle in this trip is determined to be a high-frequency parking location. If the navigation function is enabled during this trip, and the parking location is the destination of this navigation, and the parking location is not one of the preset frequently used locations, then the parking location type of the target vehicle during this trip is determined to be a low-frequency parking location. If the navigation function is not enabled during this trip, and the cumulative number of times the parking location overlaps with the historical navigation destination is greater than or equal to the second threshold, the parking location type of the target vehicle during this trip is determined to be a low-frequency parking location. If the current parking time period falls within the second statistical period, and the annual cumulative number of parking times at the parking location is greater than or equal to the second threshold, then the parking location type of the target vehicle in this trip is determined to be a low-frequency parking location. When navigation is enabled during this trip, and the distance between the parking location and the navigation destination is less than or equal to a preset distance threshold, the parking location of the target vehicle during this trip is determined to be a temporary parking location. If navigation is not enabled during this trip, and the geographic location keyword corresponding to the parking location is a preset temporary parking keyword, then the parking location type of the target vehicle during this trip is determined to be a temporary parking location.

[0008] In one embodiment, the target vehicle is provided with a correspondence between reminder scenarios and reminder strategies of different risk levels. The risk level represents the degree of risk of items being left behind in the corresponding reminder scenario. The higher the risk level of the reminder scenario, the stronger the reminder strategy. The method of employing a reminder strategy corresponding to the current reminder scenario of the vehicle-mounted refrigerator / warmer to send a reminder message to the user indicating that an item has been left behind includes: Based on the aforementioned correspondence, a reminder strategy corresponding to the current reminder scenario of the vehicle-mounted refrigerator / warmer is adopted to send a reminder message to the user indicating that items have been left behind.

[0009] In one embodiment, the method for determining the current alert scenario of the vehicle-mounted refrigerator / warmer includes at least one of the following: If the parking location type is any of the high-frequency parking location, low-frequency parking location, or temporary parking location, the operating state is a delayed temperature control state, and the door opening and closing behavior is any of the opening and closing behaviors, then it is determined that the vehicle-mounted refrigerator / warmer is currently in the first reminder scenario. If any of the following conditions are met: the parking location type, the operating status of the vehicle-mounted refrigerator / warmer, and the door opening / closing behavior, then the vehicle-mounted refrigerator / warmer is determined to be in the second reminder scenario: Condition 1: The parking location type is a high-frequency parking location, the operating state is the vehicle power-off state, and the door opening and closing behavior is a brief opening behavior; Condition 2: The parking location type is a low-frequency parking location, the operating state is the vehicle-power-off state, and the door opening / closing behavior is a brief opening behavior; Condition 3: The parking location type is a temporary parking location, the operating state is the vehicle power-off state, and the door opening / closing behavior is no door opening behavior; If the parking location type is a high-frequency parking location, the operating status is a power-off state or an actively closed state, and the door opening / closing behavior is no opening behavior, then it is determined that the vehicle-mounted refrigerator / warmer is currently in the third reminder scenario. If the parking location type is a low-frequency parking location and the operating state is the vehicle-off state. If the door is actively closed and the door opening behavior is no opening behavior, then the vehicle-mounted refrigerator / warmer is currently in the fourth reminder scenario. The risk level of the first reminder scenario is less than the risk level of the second reminder scenario, which is less than the risk level of the third reminder scenario, which is less than the risk level of the fourth reminder scenario.

[0010] In one embodiment, the correspondence includes the correspondence between a first reminder scenario and a first reminder strategy, the correspondence between a second reminder scenario and a second reminder strategy, the correspondence between a third reminder scenario and a third reminder strategy, and the correspondence between a fourth reminder scenario and a fourth reminder strategy. The first reminder strategy includes: each time the first reminder scenario is in effect, if the temperature control is not turned on again after the delayed temperature control state ends, a reminder message about the item being left behind will be sent to the user through the mobile terminal application; The second reminder strategy includes: when the user is first in the second reminder scenario within a preset time period, no reminder is executed when the user leaves the target vehicle; when the target vehicle is detected to be moving again, a prompt icon for a preset duration is displayed on the vehicle's in-vehicle display device as a reminder that the item was left behind; no reminder is executed when the user is in the second reminder scenario again within the preset time period. The third reminder strategy includes: when the third reminder scenario is first encountered within a preset time period, and the driver's side door of the target vehicle is detected to be open, a reminder message indicating that an item has been left behind is issued through the vehicle's in-vehicle voice device; when the third reminder scenario is encountered again within the preset time period, no reminder is issued. The fourth reminder strategy includes: each time the fourth reminder scenario is in effect, when the driver's side door of the target vehicle is detected to be open, a reminder message indicating that an item has been left behind is issued through the vehicle's in-vehicle voice device.

[0011] Secondly, this application provides a notification device for an in-vehicle refrigerator / heater box, comprising: The monitoring module is used to monitor whether the target vehicle containing the vehicle-mounted heat and cold box is in a parked state; The acquisition module is used to acquire, if the target vehicle is in a parked state, the parking location type of the target vehicle, the operating status of the vehicle-mounted refrigerator / warmer box, and the door opening / closing behavior of the vehicle-mounted refrigerator / warmer box; the parking location type is a high-frequency parking location, a low-frequency parking location, or a temporary parking location; The determination module is used to determine the current reminder scenario of the vehicle-mounted refrigerator / warmer based on the parking location type, the operating status of the vehicle-mounted refrigerator / warmer, and the door opening / closing behavior. The notification module is used to send a notification message to the user that an item has been left behind, using a notification strategy corresponding to the current notification scenario of the vehicle-mounted refrigerator / warmer.

[0012] Thirdly, embodiments of this application provide a control device, including: a processor, a storage medium, and a bus. The storage medium stores program instructions executable by the processor. When the control device is running, the processor communicates with the storage medium via the bus, and the processor executes the program instructions to implement the notification method for the vehicle-mounted refrigerator / heater box described in any embodiment.

[0013] Fourthly, this application provides a vehicle, including: an on-board refrigerator / heater and a control device; the control device is communicatively connected to the on-board refrigerator / heater, and the control device is used to execute the on-board refrigerator / heater notification method described in any embodiment.

[0014] The beneficial effects of this application are as follows: This application provides a method for alerting users of an in-vehicle refrigerator / warmer. This method monitors the vehicle's parking status and obtains three types of data: the type of parking location, the operating status of the in-vehicle refrigerator / warmer, and the opening and closing behavior of the refrigerator door. Based on the scenario, it determines whether to remind the user. It does not require weight or image sensors, avoiding false alarms caused by vibration, water accumulation, or low-temperature frost. It also does not use an in-vehicle camera, eliminating privacy risks. Furthermore, it does not increase hardware costs throughout the process. Accurate reminders can be achieved through scenario-based judgment, fundamentally solving the problems of high reminder costs, easy false alarms, and significant privacy risks.

Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0020] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0021] This application provides a method for providing a notification for an in-vehicle refrigerator / heater. This method can be generated by any control device with computing and processing capabilities, such as an in-vehicle controller.

[0022] The following examples, in conjunction with the accompanying drawings, provide specific illustrations of the prompting method for the vehicle-mounted refrigerator / heater box provided in this application.

[0023] Figure 1 This is a flowchart illustrating the notification method for an in-vehicle refrigerator / heater box provided in an embodiment of this application, as shown below. Figure 1 As shown, the method includes: S11. Monitor whether the target vehicle containing the vehicle-mounted heat and cooler box is in a parked state.

[0024] A vehicle-mounted refrigerator / heater box refers to a vehicle-mounted storage device installed inside the vehicle and powered by the vehicle's power supply. Examples include a vehicle-mounted refrigerator with a cooling mode that can refrigerate or freeze; a vehicle-mounted thermostat box with a heating mode that can keep warm or heat up; a vehicle-mounted refrigerator / heater box with dual-mode temperature control for both cooling and heating, and a vehicle-mounted thermostat box, etc.

[0025] The system collects real-time gear position and speed signals of the target vehicle where the in-vehicle air cooler / heater is located. When the gear is in park and the speed is 0 km / h, the target vehicle is determined to be in a parked state. This step ensures that the in-vehicle air cooler / heater's alert method is triggered only when the vehicle is stationary and the user is preparing to leave, avoiding accidental triggering while the vehicle is in motion.

[0026] S12. If the target vehicle is in a parked state, obtain the target vehicle's parking location type, the operating status of the on-board refrigerator / heater, and the on-board refrigerator / heater door opening / closing behavior.

[0027] Once the vehicle is confirmed to be parked, immediately collect information on the type of parking location, the operating status of the onboard refrigerator / heater, and the opening and closing behavior of the refrigerator / heater door.

[0028] The parking location type includes the location of the parking spot; the operating status of the vehicle-mounted refrigerator / heater includes whether the refrigerator / heater is working and the closing method (power off with vehicle, automatic closing, delayed closing). Power off with vehicle means that the vehicle-mounted refrigerator / heater automatically closes when the vehicle is turned off. Automatic closing means that the user manually closes the vehicle-mounted refrigerator / heater. Delayed closing means that the vehicle-mounted refrigerator / heater continues to work for a period of time (e.g., 30 minutes) when the vehicle is turned off.

[0029] The door opening and closing behavior of the vehicle refrigerator / warmer includes whether the user opened the door during the vehicle's journey and the duration of the opening. For example, user behavior signals may include no opening (the door was not opened at all, and items may have been left behind), brief opening (the door was opened for less than 10 seconds, and items may have been taken out), and continuous opening (the door was opened for more than 10 seconds, and items have been taken out).

[0030] S13. Determine the current reminder scenario of the vehicle-mounted refrigerator / heater based on the type of parking location, the operating status of the refrigerator / heater, and the opening / closing behavior of the refrigerator door.

[0031] The system matches the parking location type, the operating status of the vehicle-mounted refrigerator / warmer, and the door opening / closing behavior with preset reminder scenarios. If the match is successful, it determines that the vehicle-mounted refrigerator / warmer is in the preset reminder scenario, indicating a risk of items being left behind, and requires reminding the user.

[0032] S14. Employ a reminder strategy that corresponds to the current reminder scenario of the vehicle-mounted refrigerator / warmer box to send a reminder message to the user that items have been left behind.

[0033] Based on the identified reminder scenario, different reminder strategies are adopted for different scenarios to send reminder messages to users about items left behind. The reminder strategies include, but are not limited to, reminder methods and reminder frequency.

[0034] In summary, this embodiment provides a method for alerting users of an in-vehicle refrigerator / warmer. This method monitors the vehicle's parking status and acquires three types of data: the type of parking location, the operating status of the in-vehicle refrigerator / warmer, and the opening and closing behavior of the refrigerator door. Based on the scenario, it determines whether to alert the user. It eliminates the need for sensors to determine whether there are items inside the refrigerator, thus avoiding false alarms caused by vibration, water accumulation, or low-temperature frost. It also eliminates the need for in-vehicle cameras, thus avoiding privacy risks. Furthermore, it does not increase hardware costs throughout the process. Accurate alerts can be achieved through scenario-based judgment, fundamentally solving the problems of high alert costs, high false alarm rates, and significant privacy risks.

[0035] This application also provides a method for monitoring whether a target vehicle is in a parked state. Figure 2 This is a schematic diagram of the parking status monitoring process provided in the embodiments of this application, such as... Figure 2 As shown, before executing step S11 to monitor whether the target vehicle containing the on-board refrigerator / heater is in a parked state, the method of this application further includes: S101. During a single vehicle trip, determine whether the cumulative running time of the on-board heating / cooling box is greater than or equal to a preset time threshold.

[0036] During a single driving cycle of the target vehicle, from power-on to power-off, the cumulative runtime of the onboard refrigerator / heater is recorded in real time, and it is determined whether the cumulative runtime of the onboard refrigerator / heater is greater than or equal to a preset time threshold. The preset time threshold can be, for example, 10 minutes.

[0037] S11 The monitoring of whether the target vehicle where the vehicle-mounted cooling and heating box is located is in a parked state includes: S111 If the cumulative running time is greater than or equal to a preset time threshold, then monitor whether the target vehicle where the vehicle-mounted cooling and heating box is located is in a parked state.

[0038] If the cumulative running time of the vehicle's refrigerator / warmer is less than 10 minutes, it means that the user may have opened it temporarily, and there is likely no valuable / perishable item that needs to be stored inside. No reminder is needed. Only when the cumulative running time of the vehicle's refrigerator / warmer is greater than or equal to 10 minutes is it considered that the vehicle's refrigerator / warmer has been used and enters the subsequent parking monitoring and reminder process.

[0039] By setting a threshold for the cumulative running time of the vehicle-mounted refrigerator / warmer, risk-free scenarios such as short-term temporary opening can be filtered out. Only actual usage scenarios involving storing items will trigger the reminder process, improving the accuracy of reminders and avoiding excessive reminders that may cause user annoyance.

[0040] Figure 3This is a flowchart illustrating the multi-dimensional information collection and alert scenario determination process provided in the embodiments of this application, such as... Figure 3 As shown, S12, obtaining the parking location type of the target vehicle, the operating status of the onboard refrigerator / warmer, and the door opening / closing behavior of the onboard refrigerator / warmer, includes: S121. Obtain the parking location of the target vehicle and determine the parking location type based on the parking location.

[0041] The parking location type is determined based on the parking location, the target vehicle's navigation settings (indicating whether the user used navigation during the vehicle's journey), the current parking time period, and the historical parking frequency of the parking location.

[0042] Parking locations are categorized into high-frequency parking locations, low-frequency parking locations, and temporary parking locations. High-frequency parking locations are the user's usual parking spots, familiar places where the user frequently stops. Low-frequency parking locations are non-regular, unfamiliar locations where the user goes out for errands, leisure activities, or visiting relatives. Temporary parking locations are short-term rest stops during the journey, where the user will return to the vehicle and only stay briefly.

[0043] The criteria for determining a high-frequency parking location can include two situations. First, if the navigation function is not enabled during this trip, the current parking time period belongs to the first statistical period, and the number of times the target vehicle has parked at this parking location in the past first statistical period is greater than or equal to the first threshold, then the parking location type of the target vehicle in this trip is determined to be a high-frequency parking location.

[0044] For example, if the first statistical period is set to the morning or evening peak hours on weekdays (Monday to Friday), and the threshold for the first count is 3, then the high-frequency parking location can be either high-frequency parking location 1 or high-frequency parking location 2. High-frequency parking location 1 is a location where, without using navigation, the historical parking frequency is ≥3 times / week between 7:00 AM and 10:00 AM on weekdays; high-frequency parking location 2 is a location where, without using navigation, the historical parking frequency is ≥3 times / week between 6:00 PM and 12:00 AM on weekdays.

[0045] Secondly, when the navigation function is enabled for this trip and the parking location is a preset frequently used location pre-entered in the navigation application, the parking location type of the target vehicle in this trip is determined to be a high-frequency parking location.

[0046] For example, in this case, the high-frequency parking location 3 is a navigation app, and the parking location is a preset frequently used location pre-entered in the navigation app.

[0047] The criteria for determining a low-frequency parking location can include three situations. First, if the navigation function is enabled for this trip, the parking location is the destination of this navigation, and the parking location is not among the preset frequently used locations pre-entered in the navigation app, then the parking location of the target vehicle in this trip is determined to be a low-frequency parking location.

[0048] For example, in this case, low-frequency parking location 1 is a navigation location, and the destination of this navigation is not a frequently used address set in the navigation app (it is neither a high-frequency parking location for daily commuting nor a frequently used address set by the navigation app itself, and is therefore determined to be a low-frequency parking location).

[0049] Secondly, if the navigation function is not enabled during this trip, and the cumulative number of times the parking location overlaps with the historical navigation destination is greater than or equal to the second threshold, the parking location type of the target vehicle during this trip is determined to be a low-frequency parking location.

[0050] For example, if the threshold for the second count is set to 5, then low-frequency parking location 2 is a location that does not use navigation, but whose cumulative number of times the parking location overlaps with the historical navigation destination is ≥5 (the cumulative number of navigation times ≥5 is used to filter locations that are only visited once or twice, and only locations that are occasionally visited but are not part of the daily commute are classified as low-frequency parking locations. Moreover, even if the cumulative number of overlaps with the location is ≥5, the user's visit interval is still relatively long, which is different from high-frequency parking locations where the user parks more than 3 times per week).

[0051] Third, if the current parking period falls within the second statistical period and the annual cumulative number of parking visits at the parking location is greater than or equal to the second threshold, the parking location type for the target vehicle during this trip is determined to be a low-frequency parking location.

[0052] For example, the second statistical period is statutory holidays. In this case, low-frequency parking location 3 is a location with an annual cumulative parking frequency of ≥5 times during statutory holidays (parking more than 5 times, but the time span is one year, and the visits are only during holidays and not on weekdays, which is different from high-frequency parking locations with more than 3 times per week).

[0053] The criteria for determining a temporary parking location can include two situations. First, if the navigation function is enabled during this trip, and the distance between the parking location and the destination is less than or equal to a preset distance threshold, then the parking location of the target vehicle during this trip is determined to be a temporary parking location.

[0054] For example, if the preset distance threshold is 3 kilometers, then temporary parking location 1 is a location 3 kilometers away from the destination when using navigation.

[0055] Secondly, if the navigation function is not enabled for this trip, and the geographic location keyword corresponding to the parking location is a preset temporary parking keyword, the parking location type of the target vehicle in this trip is determined to be a temporary parking location.

[0056] For example, preset temporary parking keywords include, but are not limited to, "highway", "service", "temporary" and "rest". In this case, temporary parking location 2 does not use navigation. It retrieves the geographic location keywords based on the vehicle's current parking location. The obtained geographic location keywords include at least the locations with "highway", "service", "temporary" and "rest".

[0057] Optionally, this application also provides a method for determining parking location type based on historical parking frequency: the on-board controller records the geographical location of the target vehicle each time it parks and stores the historical parking frequency corresponding to each geographical location; a frequency determination threshold is preset, and when the target vehicle is detected to be parked, the historical parking frequency of that parking location is retrieved, and the historical parking frequency is compared with the frequency determination threshold. Locations with historical parking frequencies higher than the frequency determination threshold are classified as high-frequency parking locations, and locations with historical parking frequencies lower than the frequency determination threshold are classified as low-frequency parking locations; at the same time, short-term parking locations such as highways, service areas, and temporary rest areas are defined as temporary parking locations, thereby completing the classification of three types of parking locations: high-frequency parking locations, low-frequency parking locations, and temporary parking locations, providing a basis for subsequent risk assessment of items left behind in the on-board refrigerator / warmer.

[0058] After accurately determining the type of parking location using this method, and combining the operating status of the vehicle-mounted refrigerator and the opening and closing behavior of the door, the current reminder scenario of the vehicle-mounted refrigerator can be accurately determined. This enables precise reminders of items left in the vehicle-mounted refrigerator, solving the problem of food spoilage or medicine becoming ineffective due to users forgetting items in the refrigerator when getting out of the car.

[0059] S122. Obtain the operating status of the vehicle-mounted cooling / heating box during the first time period.

[0060] The first time period is the period from when the target vehicle enters the parking state until the driver's side door is opened.

[0061] S123, Obtain the door opening and closing behavior of the vehicle-mounted refrigerator / heater box during the second time period.

[0062] The second time period is the time from when the vehicle's in-vehicle cooler / warmer is started until the driver's side door is opened.

[0063] S13 describes determining the current reminder scenario for the vehicle-mounted refrigerator / warmer based on the parking location type, the operating status of the refrigerator / warmer, and the door opening / closing behavior, including: S131. Determine the current reminder scenario of the vehicle-mounted hot and cold box based on the parking location type, the operating status during the first time period, and the door opening and closing behavior during the second time period.

[0064] By combining and matching the parking location type, the operating status during the first time period, and the door opening / closing behavior during the second time period, the current alert scenario for the vehicle-mounted refrigerator / warmer is determined. This embodiment uses a combined approach based on three factors—parking location type, operating status, and door opening / closing behavior—to fully align with actual user habits and significantly improve the accuracy of identifying the risk of items being left behind.

[0065] In another embodiment, the target vehicle is equipped with a correspondence between reminder scenarios and reminder strategies of different risk levels. The risk level represents the degree of risk of items being left behind in the corresponding reminder scenario. The higher the risk level of the reminder scenario, the stronger the reminder strategy.

[0066] S14 describes using a reminder strategy corresponding to the current reminder scenario of the vehicle-mounted refrigerator / warmer to send a reminder message to the user about items left behind. This includes: based on the correspondence between reminder scenarios and reminder strategies of different risk levels, using a reminder strategy corresponding to the current reminder scenario of the vehicle-mounted refrigerator / warmer to send a reminder message to the user about items left behind.

[0067] The alert strength is an indicator of the effectiveness of warnings regarding left-behind items. A higher alert strength indicates a stronger warning. For example, alert strength can be measured by the number of alert methods and / or the frequency of alerts. For instance, alert strategy A uses both in-vehicle audio and a mobile app to alert users about left-behind items, while alert strategy B uses only in-vehicle audio. This indicates that alert strategy A has a higher alert strength than alert strategy B. Similarly, alert strategy C alerts users every time a warning scenario occurs, while alert strategy D only alerts them the first time a warning scenario occurs. This indicates that alert strategy C has a higher alert strength than alert strategy D. The higher the risk level of the warning scenario, the higher the risk level of left-behind items, and therefore the higher the configured alert strength.

[0068] Based on this, the methods for determining the current alert scenario of the vehicle-mounted cooler / warmer include at least one of the following: In one embodiment, if the parking location type is any of the high-frequency parking location, low-frequency parking location, or temporary parking location, the operating state is delayed temperature control, and the door opening and closing behavior is any of the switching behaviors, then the vehicle-mounted refrigerator / warmer is determined to be in the first reminder scenario (delayed temperature control is a function actively selected by the user, indicating that the user knows that there are items placed in the vehicle-mounted refrigerator / warmer, and that they have not completely forgotten about it after putting it away. Therefore, the risk of items being left behind is the lowest in this case).

[0069] The reminder strategy corresponding to the first reminder scenario is the first reminder strategy. In this case, the reminder strategy corresponding to the current reminder scenario of the vehicle-mounted refrigerator / warmer box, as described in S14, is used to send a reminder message to the user that an item has been left behind. This includes: using the first reminder strategy corresponding to the first reminder scenario to send a reminder message to the user that an item has been left behind. For example, the reminder message is sent to the user based on the reminder frequency and reminder method corresponding to the first reminder strategy.

[0070] Among them, the reminder frequency corresponding to the first reminder strategy is the first reminder frequency, and the reminder method corresponding to the first reminder strategy is that if the temperature control is not turned on again after the delayed temperature control period ends, a reminder message about the item being left behind will be sent to the user through the mobile terminal application.

[0071] For example, the first reminder frequency is triggered every time the first reminder scenario is triggered, and the delayed temperature control period is when more than 30 minutes have passed since the delayed temperature control state ended. In this case, when the vehicle refrigerator is in the first reminder scenario, if the temperature control is not restarted after more than 30 minutes after the delayed temperature control state ends, a message indicating that items have been left behind will be sent to the user via the mobile application. The message could be a text message such as "Hello, the delayed temperature control in your vehicle has ended. The vehicle refrigerator has not been restarted for a long time, and the items stored in the refrigerator are at risk of spoilage. We suggest you return to your vehicle as soon as possible to retrieve the items."

[0072] When the in-vehicle cooler / warmer is in the first alert scenario, it will alert the user after the delayed temperature control period ends, which meets the user's expectation of delayed storage and ensures that the items will not fail due to prolonged power outages.

[0073] In another embodiment, the vehicle-mounted refrigerator / warmer is determined to be in the second reminder scenario if any of the following conditions are met: parking location type, vehicle-mounted refrigerator / warmer operating status, and door opening / closing behavior: Condition 1: If the parking location type is a high-frequency parking location, the operating status is "power off with vehicle", and the door opening behavior is a brief opening behavior, then the vehicle-mounted refrigerator / warmer box is determined to be in the second reminder scenario (the parking location type is a high-frequency parking location, which means that the user is likely to return to the vehicle again in a short time, and the door opening behavior is a brief opening behavior, which means that the user has opened the door and knows the contents of the box, so the risk of leaving items behind is low in this case).

[0074] Condition 2: If the parking location type is a low-frequency parking location and the operating status is "power off with vehicle", and the door opening behavior is a brief opening behavior, then the vehicle-mounted refrigerator / warmer box is determined to be in the second reminder scenario (although the parking location type is a low-frequency parking location, the door opening behavior is a brief opening behavior, indicating that the user has opened the door and knows the contents of the box, so the risk of items being left behind is low in this case).

[0075] Condition 3: If the parking location type is a temporary parking location, the operating status is "power off with vehicle", and the door opening behavior is "no door opening behavior", then the vehicle-mounted refrigerator / warmer is determined to be in the second reminder scenario (the parking location type is a temporary parking location, and the scenario attribute determines that the user stays at this location for a short time. Even if the door is not opened, the user will return to the vehicle in a short time. Therefore, the risk of items being left behind is low in this case).

[0076] The reminder strategy corresponding to the second reminder scenario is the second reminder strategy. In this case, the reminder strategy corresponding to the reminder scenario in which the vehicle-mounted refrigerator / warmer is currently located, as described in S14, is used to send a reminder message to the user that an item has been left behind. This includes: using the second reminder strategy corresponding to the second reminder scenario to send a reminder message to the user that an item has been left behind. For example, the reminder message is sent to the user based on the reminder frequency and reminder method corresponding to the second reminder strategy.

[0077] The second reminder strategy corresponds to the second reminder frequency, and the reminder method corresponding to the second reminder strategy is to display a prompt icon for a preset duration on the vehicle's in-vehicle display device when the target vehicle is detected to be driving again, as a reminder message that the item has been left behind.

[0078] For example, the second reminder frequency is triggered when the vehicle-mounted refrigerator / warmer box first enters the second reminder scenario, and the reminder is not triggered again when it enters the second reminder scenario again within a preset time period. The reminder policy is reset after the preset time period is exceeded.

[0079] In one example, when the in-vehicle refrigerator / warmer is in the second alert scenario, no alert is triggered when the user opens the car door to get out or locks the car and leaves the vehicle. When the user gets back into the car and starts the vehicle again, and the target vehicle is detected to be moving again, a notification icon will be displayed on the target vehicle's in-vehicle display for a preset duration as a notification message indicating that the item has been left behind (for example, a notification icon will be displayed on the vehicle's central control screen for 30 seconds; the notification icon can be a graphic or a combination of graphic and text, such as only showing a simple outline of the in-vehicle refrigerator, or a refrigerator image with a warning exclamation mark; it can also be a graphic pop-up window with a brief message "Please check the in-vehicle refrigerator" next to the icon; the pop-up window will be displayed for 30 seconds and then disappear automatically). The preset time period is one month. If the user is in one of these three scenarios a second time within a month, it is assumed that the user is aware of the risk, and the icon will no longer pop up. The alert strategy will be reset in the second month, that is, the first alert rule will be restored in the second month. When the user is in the second alert scenario for the first time in the second month, an alert will be triggered, but if the user is in one of these three scenarios again in the second month, no alert will be triggered, and so on in the third month.

[0080] In conditions one and two of the second reminder scenario, the user opens the compartment door and knows the contents of the compartment. In condition three of the second reminder scenario, the user will return to the vehicle shortly. Therefore, the risk of items being left behind is low under these three conditions. In this embodiment, a weak reminder is given via an icon when the vehicle starts moving again, which does not affect the user getting out of the vehicle. Furthermore, combined with the monthly reminder frequency limit, repeated reminders are avoided, balancing safety and user experience, and completing the item leaving risk warning with almost no awareness.

[0081] In another embodiment, if the parking location type is a high-frequency parking location, the operating status is a power-off state or an actively closed state, and the door opening behavior is not a door opening behavior, then the vehicle-mounted refrigerator / warmer is determined to be in the third reminder scenario (the user has not opened the door and does not know the contents of the box, and there is a risk of forgetting, but the parking location type is a high-frequency parking location, and the user is likely to return to the car soon, so the risk of leaving the items is moderate in this case).

[0082] The reminder strategy corresponding to the third reminder scenario is the third reminder strategy. In this case, the reminder strategy corresponding to the current reminder scenario of the vehicle-mounted refrigerator / warmer box described in S14 is used to send a reminder message to the user that an item has been left behind. This includes: using the third reminder strategy corresponding to the third reminder scenario to send a reminder message to the user that an item has been left behind. For example, according to the reminder frequency and reminder method corresponding to the third reminder strategy, a reminder message to the user that an item has been left behind is sent.

[0083] The third reminder strategy corresponds to the third reminder frequency, and the reminder method is as follows: when the driver's side door of the target vehicle is detected to be open, a reminder message indicating that an item has been left behind is issued through the vehicle's in-vehicle voice device.

[0084] For example, the third reminder frequency is triggered when the vehicle-mounted refrigerator / warmer box first enters the third reminder scenario, and the reminder will not be triggered again when it enters the third reminder scenario again within a preset time period. The reminder policy will be reset after the preset time period is exceeded.

[0085] In one example, when the in-vehicle refrigerator / warmer is in the third reminder scenario, before the user opens the driver's side door and is about to get out of the car, a message indicating that items have been left behind is issued through the vehicle's in-vehicle voice device (e.g., an announcement via the vehicle's speaker saying "Please check the in-vehicle refrigerator / warmer to prevent items from being left behind"). The preset time period is one month. If the user is in the third reminder scenario a second time within a month, it is assumed that the user is aware of the risk, and the icon will no longer pop up. The reminder policy is reset in the second month, that is, the first reminder rule is restored in the second month. If the user is in the third reminder scenario for the first time in the second month, the reminder will be executed. If the user is in the third reminder scenario again in the second month, no reminder will be issued. This process continues in the third month.

[0086] If the parking location is a low-frequency parking location, the operating status is either powered off with the vehicle or actively closed, and there is no door opening behavior, then the vehicle-mounted refrigerator / warmer is determined to be in the fourth reminder scenario (the user has not opened the door, is unaware of the contents of the box, and there is a risk of forgetting items; in addition, since the parking location is a low-frequency parking location, the user is unlikely to return in the short term after leaving, or even return on the same day, so the risk of items being left behind is high).

[0087] The reminder strategy corresponding to the fourth reminder scenario is the fourth reminder strategy. In this case, the reminder strategy corresponding to the current reminder scenario of the vehicle-mounted refrigerator / warmer box is adopted in S14 to send the user a reminder message about items left behind. This includes: using the fourth reminder strategy corresponding to the fourth reminder scenario to send the user a reminder message about items left behind. For example, according to the reminder frequency and reminder method corresponding to the fourth reminder strategy, the user is sent a reminder message about items left behind.

[0088] The fourth reminder strategy corresponds to the fourth reminder frequency, and the reminder method is to issue a message indicating that an item has been left behind through the vehicle's in-vehicle voice device when the driver's side door of the target vehicle is detected to be open.

[0089] For example, the fourth reminder frequency is triggered every time the in-vehicle refrigerator / warmer is in the fourth reminder scenario. When the in-vehicle refrigerator / warmer is in the fourth reminder scenario, before the user opens the driver's side door and is about to get out of the car, a message indicating that items have been left behind is broadcast through the vehicle's in-vehicle voice system (e.g., "Please check the in-vehicle refrigerator / warmer to prevent items from being left behind" is announced through the vehicle's speaker). The difference between the third and fourth reminder scenarios lies in the risk of items being left behind: the risk is high in the fourth reminder scenario, medium in the third, and higher in the fourth. Therefore, a monthly reset reminder strategy is not used in the fourth reminder scenario; instead, the user needs to be reminded every time to reduce the loss caused by items being left behind.

[0090] This embodiment uses a strong reminder method of voice prompts upon opening the door to ensure that users receive notifications of items left behind as soon as possible.

[0091] In summary, the risk level of the first reminder scenario is lower than that of the second reminder scenario, which is lower than that of the third reminder scenario, which is lower than that of the fourth reminder scenario. The reminder strength of the first reminder strategy is also lower than that of the second, third, and fourth reminder strategies. The above specific implementation methods for determining whether the vehicle-mounted refrigerator / warmer is in a preset reminder scenario achieve an optimal balance between preventing users from leaving items behind and avoiding disturbing users, as the higher the risk of items being left behind, the stronger the reminder method becomes.

[0092] This application also provides a vehicle, including an onboard refrigerator / heater and a control device, wherein the control device is communicatively connected to the onboard refrigerator / heater and is used to execute the prompting method for the onboard refrigerator / heater described in any embodiment.

The specific implementation process and the resulting technical effects are the same as those in the corresponding method embodiments.

Figure 4 As shown, this application also provides a notification device for a vehicle-mounted refrigerator / heater box, comprising: Monitoring module 10 is used to monitor whether the target vehicle containing the vehicle-mounted heat and cold box is in a parked state.

[0095] The acquisition module 20 is used to acquire, if the target vehicle is in a parked state, the parking location type of the target vehicle, the operating status of the vehicle-mounted refrigerator / heater box, and the door opening / closing behavior of the vehicle-mounted refrigerator / heater box.

[0096] The determination module 30 is used to determine the current reminder scenario of the vehicle-mounted refrigerator / heater based on the parking location type, the operating status of the vehicle-mounted refrigerator / heater, and the door opening / closing behavior.

[0097] The prompt module 40 is used to send a prompt message to the user that an item has been left behind, using a prompt strategy corresponding to the current prompt scenario of the vehicle-mounted refrigerator / warmer.

[0098] Optionally, the monitoring module 10 is further configured to determine whether the cumulative running time of the vehicle-mounted cooling and heating box is greater than or equal to a preset time threshold during a single vehicle trip; if the cumulative running time is greater than or equal to the preset time threshold, then monitor whether the target vehicle where the vehicle-mounted cooling and heating box is located is in a parked state.

[0099] Optionally, the acquisition module 20 is further configured to acquire the parking location of the target vehicle and determine the parking location type of the target vehicle in this trip based on the parking location; acquire the operating status of the vehicle-mounted refrigerator / heater box in a first time period, the first time period being the time period from when the target vehicle enters the parking state to when the driver's side door is opened; and acquire the door opening and closing behavior of the vehicle-mounted refrigerator / heater box in a second time period, the second time period being the time period from when the vehicle-mounted refrigerator / heater box starts to when the driver's side door is opened.

[0100] The determination module 30 is also used to determine the current reminder scenario of the vehicle-mounted refrigerator / warmer box based on the parking location type, the operating status during the first time period, and the door opening / closing behavior during the second time period.

If the cumulative number of times the vehicle's location overlaps with the historical navigation destination is greater than or equal to the second threshold, the parking location type for the target vehicle in this trip is determined to be a low-frequency parking location; if the current parking time period belongs to the second statistical period, and the annual cumulative number of parking times at the parking location is greater than or equal to the second threshold, the parking location type for the target vehicle in this trip is determined to be a low-frequency parking location; if the navigation function is enabled in this trip, and the distance between the parking location and the current navigation destination is less than or equal to a preset distance threshold, the parking location type for the target vehicle in this trip is determined to be a temporary parking location; if the navigation function is not enabled in this trip, and the geographic location keyword corresponding to the parking location belongs to a preset temporary parking keyword, the parking location type for the target vehicle in this trip is determined to be a temporary parking location.

[0102] Optionally, the target vehicle is configured with a correspondence between reminder scenarios and reminder strategies of different risk levels. The risk level represents the degree of risk of an item being left behind in the corresponding reminder scenario, and the higher the risk level of the reminder scenario, the stronger the reminder strategy. The reminder module 40 is further configured to, based on the correspondence, adopt a reminder strategy corresponding to the current reminder scenario of the vehicle-mounted refrigerator / warmer, and send an item-left-behind reminder message to the user.
