[0002] During the use of the vehicle, many car owners will leave items or pets, children, etc. in the car due to carelessness. In the prior art, it is usually based on sensors such as cameras and millimeter-wave radars installed in the car to identify whether there are any leftovers in the car. If there are any leftovers, one way to remind the user is that the vehicle sends an alarm to remind the owner. Based on this reminder method, if the owner has walked away or failed to hear the alarm, there is a problem that the user cannot find the leftovers in time, so this reminder method has limitations. Another way to remind the user is that the vehicle establishes a network connection with a mobile terminal such as the owner's mobile phone, and sends a reminder message to the mobile terminal to notify the owner that there are leftovers in the car. Based on this reminder method, if the owner leaves the mobile terminal in the car, there is also a problem that the owner cannot be notified in time, so this reminder method also has limitations.

[0030] As mentioned above, during the use of the vehicle, many car owners will carelessly leave items or pets, children, etc. in the car.

[0031] With the continuous upgrading of vehicle configuration, vehicles equipped with in-vehicle cameras, in-vehicle millimeter-wave radars and other sensors are becoming more and more common. In addition, vehicles will be equipped with high-computing power central processing units. Currently, the in-vehicle cameras, millimeter-wave radars and other sensors collect video or point cloud data inside the vehicle and send it to the central processing unit. The central processing unit can then identify in the corresponding algorithm model whether there are any specified types of leftover items (i.e., relics) at specified locations in the vehicle.

[0032] In the prior art, if it is determined that there is something left behind in the car, one way to remind the user is to control the vehicle to give a voice prompt or control the vehicle warning light to flash and sound an alarm to remind. In this way, if the owner has walked far away or fails to hear the alarm, there is a problem that the user cannot find the left behind in time. Therefore, this reminder method has limitations.

[0033] Another way to remind the user is for the vehicle to send a reminder message to a mobile terminal. This reminder method also has the problem of not being able to notify the owner in time if the owner leaves the mobile terminal in the car. Therefore, this reminder method also has limitations. In addition, this method sends reminder messages through network communication. Under conditions where the wireless network environment is not good (for example, when the vehicle is in an underground parking lot or other places with poor network conditions), the vehicle cannot send the reminder message to the mobile terminal in time, which also has certain limitations.

[0034] Therefore, the current reminder of left-behind items in the car can only be fixed on a mobile terminal (such as a mobile phone), a car screen, or outside the car through visual or auditory reminders. However, when the network environment is poor or the user leaves the vehicle quickly, the reminder of left-behind items cannot dynamically switch the reminder mode according to the user's location status inside and outside the car and the network connection status, and it is impossible to ensure that the left-behind item reminder message can be accurately and timely given to the user. Therefore, the existing reminder method for left-behind items in the car has the problem of not being able to remind the user in time and has certain limitations.

[0035] Based on this, the implementation method of the present application provides a method and system for reminding the owner of leftovers in a vehicle, wherein, based on the positional relationship of the wearable device and the mobile device relative to the vehicle, if the wearable device and the mobile device are both in the vehicle, it is considered that the owner is in the vehicle, and a reminder message for leftovers is presented through the vehicle; if the wearable device is in the vehicle and the mobile device is not in the vehicle, it is considered that the owner may or may not be in the vehicle, and a reminder message for leftovers is presented through the vehicle and / or through the mobile device; if the wearable device is not in the vehicle, it is considered that the owner is not in the vehicle, and a reminder message for leftovers is presented through the wearable device, so that the owner can find the leftovers in time, and multiple reminder methods can ensure that the reminder message for leftovers can be received and known by the owner, thereby serving as an effective reminder.

[0036] Next, the method and system for reminding of objects left behind in a vehicle provided by the implementation of the present application are described in detail.

[0037] In one implementation of the present application, Figure 1 As shown, the in-vehicle left-behind reminder system includes a vehicle, a mobile device and a wearable device, and the vehicle establishes communication connections with the mobile device and the wearable device respectively.

[0038] In one implementation of the present application, a vehicle establishes communication connections with a mobile device and a wearable device respectively based on ultra-wideband (Ultra Wide Band, UWB) wireless carrier communication technology.

[0039] Among them, ultra-wideband wireless carrier communication technology has the advantages of low power consumption, high data transmission rate, high penetration capability, high ranging accuracy, etc., and has low cost, and is easy to deploy on the vehicle side (ie the car side) and the mobile device side.

[0040] In another implementation of the present application, the vehicle can also establish communication connections with the mobile device and the wearable device respectively based on wireless connection methods such as Bluetooth (also known as BT) or WIFI.

[0041] Among them, the vehicle is used to generate a legacy reminder message when it is determined that there are relics in the vehicle, and determine a first relative position relationship between the vehicle and the wearable device, and determine a second relative position relationship between the vehicle and the mobile device, and determine the presentation method of the legacy reminder message based on the first relative position relationship and the second relative position relationship, wherein if the wearable device and the mobile device are both in the vehicle, the vehicle presents a legacy reminder message, if the wearable device is in the vehicle and the mobile device is not in the vehicle, the vehicle presents a legacy reminder message, and / or the vehicle sends a legacy reminder message to the mobile device so that the mobile device presents the legacy reminder message, and if the wearable device is not in the vehicle, the vehicle sends a legacy reminder message to the wearable device so that the wearable device presents the legacy reminder message.

[0042] For example, if both the wearable device and the mobile device are in the vehicle, it is considered that the user is in the vehicle, and the vehicle presents a left-behind reminder message to remind the user.

[0043] If the wearable device is in the vehicle and the mobile device is not in the vehicle, it can be considered that the user is in the vehicle, so that the vehicle presents a left-behind reminder message. Alternatively, it is considered that the user is not in the vehicle, but the wearable device is left in the vehicle, so that the vehicle sends a left-behind reminder message to the mobile device, so that the mobile device presents the left-behind reminder message. Alternatively, the vehicle presents the left-behind reminder message, and the vehicle sends the left-behind reminder message to the mobile device, so that the mobile device presents the left-behind reminder message, so as to achieve a double reminder, which can better ensure that the user can receive the left-behind reminder message.

[0044] If the wearable device is not in the vehicle, regardless of whether the mobile device is in the vehicle, it is considered that the owner is not in the vehicle, and the vehicle sends a left-behind reminder message to the wearable device, so that the wearable device displays the left-behind reminder message. In this way, even if the mobile device is left in the vehicle, the user can receive the left-behind reminder message in time through the wearable device.

[0045] The mobile device is used to present the left-behind reminder message when receiving the left-behind reminder message.

[0046] The wearable device is used to present a left-behind reminder message when receiving the left-behind reminder message.

[0047] Furthermore, if Figure 2 As shown, the vehicle left-behind reminder system also includes a cloud server.

[0048] The cloud server establishes communication connections with the vehicle, mobile device and wearable device respectively.

[0049] In one implementation of the present application, the cloud server establishes 4G, 5G and other communication connections with the vehicle, mobile device and wearable device respectively based on the cellular network.

[0050] In one implementation of the present application, the vehicle is also used to send a left-behind reminder message to a cloud server when sending the left-behind reminder message to the wearable device fails.

[0051] The cloud server is used to send a left-behind reminder message to the wearable device when receiving a left-behind reminder message sent by the vehicle, so that the wearable device presents the left-behind reminder message, and in the case of failure to send the left-behind reminder message to the wearable device, if it is determined that the mobile device is not in the vehicle, send a left-behind reminder message to the mobile device, so that the mobile device presents the left-behind reminder message. In this way, if the vehicle fails to send the left-behind reminder message to the wearable device due to poor communication connection with the wearable device, the cloud server can send the left-behind reminder message to the wearable device, if the wearable device is turned off or there is a communication failure, resulting in the cloud server failing to send the left-behind reminder message to the wearable device, and if the mobile device is not in the vehicle, send a left-behind reminder message to the mobile device, so that the reminder message of the presence of left-behind in the vehicle can be notified to the user in time.

[0052] Alternatively, the vehicle is further configured to send a left-behind reminder message to a cloud server when sending the left-behind reminder message to the wearable device fails and it is determined that the mobile device is not in the vehicle.

[0053] The cloud server is also used to send a left-behind reminder message to a mobile device when receiving a left-behind reminder message sent by the vehicle, so that the mobile device presents the left-behind reminder message, and to send a left-behind reminder message to a wearable device when the left-behind reminder message fails to be sent to the mobile device. In this way, if the vehicle fails to send a left-behind reminder message to the wearable device due to poor communication connection with the wearable device, the cloud server can send a left-behind reminder message to the mobile device. If the mobile device is turned off or there is a communication failure, which causes the cloud server to fail to send a left-behind reminder message to the mobile device, the left-behind reminder message is sent to the wearable device again, so that the reminder message of the presence of left-behind in the vehicle can be notified to the user in a timely manner.

[0054] Among them, the situation where the vehicle fails to send a left-behind reminder message to the wearable device may specifically be that the wearable device and the vehicle are far apart, resulting in a poor communication connection.

[0055] In another implementation of the present application, the vehicle is also used to send a left-behind reminder message to the mobile device if the mobile device is not in the vehicle when sending the left-behind reminder message to the wearable device fails.

[0056] Furthermore, the vehicle is also used to send a left-behind reminder message to a cloud server when sending the left-behind reminder message to a mobile device fails.

[0057] The cloud server is also used to send a legacy reminder message to the mobile device so that the mobile device presents the legacy reminder message, and in the event that sending the legacy reminder message to the mobile device fails, send the legacy reminder message to the wearable device so that the wearable device presents the legacy reminder message.

[0058] Alternatively, the cloud server is further configured to send a legacy reminder message to the wearable device so that the wearable device presents the legacy reminder message, and in the event that sending the legacy reminder message to the wearable device fails, send the legacy reminder message to the mobile device so that the mobile device presents the legacy reminder message.

[0059] In this way, if the communication connection between the vehicle and the mobile device and the wearable device is poor and the left-behind reminder message cannot be sent successfully, the cloud server can send a left-behind reminder message to the mobile device or wearable device based on the cellular network, so that the left-behind reminder message that there are left-behind objects in the vehicle can be notified to the user in time, so that the user can know in time and improve the user experience.

[0060] Furthermore, in another implementation of the present application, ultra-wideband communication devices are provided in the vehicle, the mobile device and the wearable device, a communication connection is established between the vehicle and the mobile device and the wearable device through the ultra-wideband communication device, and the vehicle determines the first relative position relationship and the second relative position relationship based on the ultra-wideband communication (i.e., UWB communication) corresponding to the ultra-wideband communication device.

[0061] In this way, wireless communication between the vehicle and the mobile device and wearable device is established based on the ultra-wideband communication device. Because the ultra-wideband communication technology has the advantages of low power consumption, high data transmission rate, high penetration capability, high ranging accuracy and low cost, it is more conducive to the communication between the vehicle and the mobile device and wearable device, and is also more conducive to the accessibility of the left-behind reminder message.

[0062] Exemplarily, the vehicle is used to provide on-board debris detection capabilities, audio output, audio input, output resources and other capabilities, and provide UWB communication connection and data transmission capabilities between the vehicle and external mobile devices and wearable devices, and support input / output of related status to the cloud server via a cellular mobile network.

[0063] like Figure 3As shown, the vehicle includes a legacy detection system (i.e., a legacy detection unit), an on-board UWB device and antenna (i.e., an ultra-wideband communication device of the vehicle), an on-board central processing system (i.e., a central processing unit), an on-board audio output system (i.e., an on-board audio output unit), an on-board video display system (i.e., an on-board video display unit), and a cellular mobile network module. The central processing unit establishes communication connections with the legacy detection unit, the on-board audio output unit, and the on-board video display unit, respectively.

[0064] Among them, the relics detection unit is used to automatically trigger the relics detection function when the vehicle meets certain external conditions (for example, the vehicle speed is zero, the gear is in P gear, or the vehicle is turned off, or the door is opened and closed, etc.), and perform relics detection processing in the vehicle. When it is determined that there are relics in the vehicle, the relevant attributes of the relics are output (for example, the relics are children / pets / keys / mobile phones / watches, etc.), and a notification message is sent to the on-board central processing system (for example, there are relics in the current vehicle, or children / pets / keys / mobile phones / watches are still in the vehicle, etc.).

[0065] The vehicle-mounted UWB device and antenna are used to establish UWB connections with mobile devices and wearable devices, and transmit pulse signals for ranging between the vehicle and the wearable device UWB device and antenna (that is, the wearable device's ultra-wideband communication device) to the vehicle-mounted central processing system, as well as transmit pulse signals for ranging between the vehicle and the mobile device UWB device and antenna (that is, the mobile device's ultra-wideband communication device).

[0066] For example, Figure 4 As shown, after three UWB devices (i.e., UWB antennas, as an example of ultra-wideband communication devices) are deployed in a vehicle and the three UWB devices are connected to the UWB devices on the mobile device side and the UWB devices on the wearable device side respectively, the on-board central processing system monitors in real time the ultra-wideband communication distance between the three UWB devices on the vehicle side and the UWB devices on the mobile device side and the UWB devices on the wearable device side, and determines in real time the relative position relationship between the mobile device, the wearable device and the vehicle based on the distance.

[0067] The vehicle-mounted central processing system is used to process various input data (including UWB communication data, cellular network data, and leftover detection data, etc.), and to judge the processed data and schedule related resources. For example, when receiving notification information, the first relative position relationship between the vehicle and the wearable device is determined based on the pulse signal between the vehicle and the wearable device sent by the vehicle, and the second relative position relationship between the vehicle and the mobile device is determined based on the pulse signal between the vehicle and the mobile device sent by the vehicle, and if it is determined that the wearable device and the mobile device are both in the vehicle according to the first relative position relationship and the second relative position relationship, the vehicle presents a leftover reminder message, if the wearable device is in the vehicle and the mobile device is not in the vehicle, the vehicle presents a leftover reminder message, and / or the vehicle sends a leftover reminder message to the mobile device so that the mobile device presents a leftover reminder message, if the wearable device is not in the vehicle, the vehicle sends a leftover reminder message to the wearable device so that the wearable device presents a leftover reminder message.

[0068] Wherein, the central processing unit determines the first relative position relationship between the vehicle and the wearable device based on the pulse signal between the vehicle and the wearable device sent by the vehicle, which can specifically be to determine whether the sent distance pulse signal is within a preset distance range. If so, it is considered that the wearable device is in the vehicle; if not, it is considered that the wearable device is not in the vehicle. The central processing unit determines the second relative position relationship between the vehicle and the mobile device based on the pulse signal between the vehicle and the mobile device sent by the vehicle, which can specifically be to determine whether the sent distance pulse signal is within a preset distance range. If so, it is considered that the mobile device is in the vehicle; if not, it is considered that the mobile device is not in the vehicle. Wherein, the preset distance range can be set according to actual conditions.

[0069] In this way, the central processing unit determines whether the wearable device and the mobile device are inside the vehicle based on the first relative position relationship between the vehicle and the wearable device, and the second relative position relationship between the vehicle and the mobile device, and then selects the corresponding left-behind reminder method, so that the left-behind reminder can be reminded in different ways based on the positions of the wearable device and the mobile device, thereby improving the accessibility of the left-behind reminder.

[0070] The vehicle audio output system is used to present the left-behind reminder message, for example, to play the left-behind reminder message and other related audio data.

[0071] The vehicle-mounted video display system is used to present a left-behind reminder message, for example, displaying the left-behind reminder message on a display screen in the vehicle.

[0072] In this way, if both the wearable device and the mobile device are in the car, it is considered that the user is in the car, so that the vehicle's on-board central processing system directly presents a left-behind reminder message on the on-board audio display unit and / or the on-board video display unit to effectively remind the user.

[0073] The cellular mobile network module is used to establish a communication connection between the vehicle and the cloud server (also known as the cloud TSP (Telematics Service Provider)), upload relevant left-behind reminder messages to the cloud server, and prompt the relevant status feedback from the cloud server.

[0074] Furthermore, the wearable device has the ability to connect and transmit data with the vehicle via UWB communication, and has the ability to communicate with the cloud TSP via cellular network. It is used to receive reminder messages of left-behind items sent by the vehicle and cloud server, and give relevant prompts on the wearable device.

[0075] Among them, wearable devices include wearable device UWB devices and antennas (that is, ultra-wideband communication devices for wearable devices), wearable device processing systems, wearable device audio output systems, wearable device video display systems, and cellular mobile network modules.

[0076] The wearable device UWB device and antenna are used to establish a UWB connection with the vehicle and transmit a pulse signal for ranging between the vehicle and the wearable device UWB device and antenna (that is, the wearable device's ultra-wideband communication device) to the vehicle.

[0077] The wearable device processing system is used to process various input data (including UWB communication data, cellular network data, and object detection data), and to make judgments on the processed data and schedule related resources. For example, when an object reminder message is received, the object reminder message is presented.

[0079] The wearable device video display system is used to present a left-behind reminder message, such as displaying the left-behind reminder message on a display screen.

[0080] The cellular mobile network module is used to establish a communication connection between the wearable device and a cloud server (ie, a cloud TSP (Telematics Service Provider)) and receive a related left-behind reminder message sent by the cloud server.

[0081] Furthermore, the mobile device has the ability to connect and transmit data with the vehicle via UWB communication, and has the ability to communicate with the cloud TSP via cellular network, and is used to receive reminder messages of left-behind items sent by the vehicle and cloud server, and to provide relevant reminders on the mobile device.

[0083] The UWB device and antenna of the mobile device are used to establish a UWB connection with the vehicle and transmit a pulse signal for ranging between the vehicle and the UWB device and antenna of the mobile device (ie, the ultra-wideband communication device of the mobile device) to the vehicle.

For example, when an object reminder message is received, the object reminder message is presented.

[0086] The mobile device video display system is used to present a left-behind reminder message, such as displaying the left-behind reminder message on a display screen.

[0087] The cellular mobile network module is used to establish a communication connection between the mobile device and the cloud server (ie, the cloud TSP (Telematics Service Provider)) and receive the related left-behind reminder message sent by the cloud server.

[0088] The cloud server (also known as cloud TSP) has the ability to receive and process relevant left-behind reminder messages uploaded by vehicles, send them to designated mobile devices or wearable devices, and perform relevant logical processing based on the sent results.

[0089] Next, the method for reminding the user of objects left behind in a vehicle provided by the implementation of the present application is described.

[0090] In the implementation of the present application, the vehicle left-behind reminder method provided by the implementation of the present application is applied to the aforementioned vehicle left-behind reminder system, such as Figure 5 As shown, the specific steps include the following steps.

[0091] S110, when the vehicle determines that there is a left-behind object in the vehicle, the vehicle generates a left-behind object reminder message, determines a first relative position relationship between the vehicle and the wearable device, and determines a second relative position relationship between the vehicle and the mobile device.

[0092] S120, the vehicle determines a presentation method of a left-behind reminder message based on a first relative position relationship and a second relative position relationship, wherein if both the wearable device and the mobile device are in the vehicle, the vehicle presents a left-behind reminder message; if the wearable device is in the vehicle and the mobile device is not in the vehicle, the vehicle presents a left-behind reminder message; and / or the vehicle sends a left-behind reminder message to the mobile device so that the mobile device presents the left-behind reminder message; if the wearable device is not in the vehicle, the vehicle sends a left-behind reminder message to the wearable device so that the wearable device presents the left-behind reminder message.

[0093] The implementation method of the present application provides a method for reminding passengers of left-behind objects in a vehicle. If a vehicle determines that there is left-behind object in the vehicle, and if it is determined that both the wearable device and the mobile device are in the vehicle based on a first relative position relationship between the vehicle and the wearable device corresponding to the vehicle, and a second relative position relationship between the vehicle and the mobile device corresponding to the vehicle, the vehicle presents a left-behind object reminder message; if the wearable device is in the vehicle and the mobile device is not in the vehicle, the vehicle presents a left-behind object reminder message, and / or the vehicle sends a left-behind object reminder message to the mobile device so that the mobile device presents the left-behind object reminder message; if the wearable device is not in the vehicle, a left-behind object reminder message is sent to the wearable device so that the wearable device presents the left-behind object reminder message. In this way, based on the positional relationship between the wearable device and the mobile device relative to the vehicle, if the wearable device and the mobile device are both in the vehicle, it is considered that the owner is in the vehicle, and a left-behind reminder message is presented through the vehicle; if the wearable device is in the vehicle and the mobile device is not in the vehicle, it is considered that the owner may or may not be in the vehicle, and a left-behind reminder message is presented through the vehicle and / or through the mobile device; if the wearable device is not in the vehicle, it is considered that the owner is not in the vehicle, and a left-behind reminder message is presented through the wearable device, so that the owner can find the left-behind in time, and multiple reminder methods can ensure that the left-behind reminder message can be received and known by the owner, thereby serving as an effective reminder.

[0094] In one implementation of the present application, when the vehicle determines that there is a leftover object, it determines a first relative position relationship between the vehicle and the wearable device, and determines a second relative position relationship between the vehicle and the mobile device, including: a leftover object detection unit performs a leftover object detection process in the vehicle, and when it is determined that there is a leftover object in the vehicle, it sends a notification message to the central processing unit.

[0095] When the central processing unit receives the notification information, it determines a first relative position relationship between the vehicle and the wearable device, and a second relative position relationship between the vehicle and the mobile device, and determines a presentation method of the left-behind reminder message based on the first relative position relationship and the second relative position relationship.

[0096] In one implementation of the present application, an ultra-wideband communication device is provided in a vehicle, a mobile device and a wearable device, a communication connection is established between the vehicle and the mobile device and the wearable device through the ultra-wideband communication device, and a central processing unit of the vehicle determines a first relative position relationship and a second relative position relationship based on the ultra-wideband communication corresponding to the ultra-wideband communication device.

[0097] Exemplarily, after three UWB devices (i.e., UWB antennas) are deployed in a vehicle and the three UWB devices establish connections with the UWB devices on the mobile device side and the UWB devices on the wearable device side respectively, the on-board central processing system monitors in real time the ultra-wideband communication distances between the three UWB devices on the vehicle side and the UWB devices on the mobile device side and the UWB devices on the wearable device side, and determines in real time the relative position relationship of the mobile device, the wearable device and the vehicle based on the communication distances of the ultra-wideband communications of each UWB device.

[0098] Furthermore, in the implementation of the present application, if both the wearable device and the mobile device are in the vehicle, it is considered that the user is in the vehicle, so that the vehicle's on-board central processing system directly presents a left-behind reminder message on the on-board audio display unit and / or the on-board video display unit to remind the user.

[0099] Therefore, in the implementation of the present application, the vehicle presents a left-behind reminder message, including: the vehicle presents the left-behind reminder message through an on-board audio display unit and / or an on-board video display unit.

[0100] Exemplarily, the vehicle plays the left-behind reminder message through the vehicle audio display unit, or displays the left-behind reminder message through the vehicle video display unit, or plays the left-behind reminder message through the vehicle audio display unit and displays the left-behind reminder message through the vehicle video display unit at the same time.

[0101] Furthermore, if the wearable device is in the vehicle and the mobile device is not in the vehicle, the user may be in the vehicle, and the vehicle's onboard central processing system directly presents a left-behind reminder message on the vehicle's onboard audio display unit and / or the vehicle's onboard video display unit.

[0102] Furthermore, if the wearable device is in the vehicle and the mobile device is not in the vehicle, the user may not be in the vehicle, but the wearable device is left in the vehicle, then the vehicle sends a left-behind reminder message to the mobile device, so that the mobile device presents the left-behind reminder message.

[0103] Furthermore, if the wearable device is in the vehicle and the mobile device is not in the vehicle, it is uncertain whether the user is in the vehicle, and the vehicle's on-board central processing system can directly present a left-behind reminder message on the on-board audio display unit and / or the on-board video display unit, and the vehicle sends a left-behind reminder message to the mobile device, so that the mobile device presents the left-behind reminder message, thereby achieving a double reminder and better ensuring that the user can receive the left-behind reminder message.

[0104] Furthermore, if the wearable device is not in the vehicle, then regardless of whether the mobile device is in the vehicle, it is considered that the user is not in the vehicle, and the vehicle sends a left-behind reminder message to the wearable device, so that the wearable device presents the left-behind reminder message. In this way, even if the mobile device is left in the vehicle, the user can receive the left-behind reminder message in time through the wearable device.

[0105] Furthermore, in another implementation of the present application, if the vehicle fails to send a left-behind reminder message to the wearable device, the left-behind reminder message can also be sent to the wearable device based on the cloud server. Figure 6 As shown, the specific steps include the following steps.

[0106] S210, when the vehicle fails to send the left-behind reminder message to the wearable device, the vehicle sends the left-behind reminder message to the cloud server.

[0107] Exemplarily, if the wearable device is not in the vehicle, the vehicle's on-board central processing system will send a message of a left-behind reminder to the wearable device via UWB and determine the result of the sending. If the left-behind reminder message is successfully sent to the wearable device, the process is terminated. If the left-behind reminder message is sent to the wearable device, the on-board central processing system will send the left-behind reminder message to the cloud TSP via the cellular network. If the message is sent to the cloud TSP successfully, the process is terminated. If the message fails to be sent to the cloud TSP, try again. If it continues to fail, keep retrying until it succeeds, or stop retrying.

[0108] Furthermore, in one implementation of the present application, the cloud server receives the left-behind reminder message, and the cloud server may also send the left-behind reminder message to the wearable device.

[0109] S220, the cloud server sends a left-behind reminder message to the wearable device, so that the wearable device presents the left-behind reminder message.

[0110] S230, when the cloud server fails to send the left-behind reminder message to the wearable device, if it is determined that the mobile device is not in the vehicle, the cloud server sends the left-behind reminder message to the mobile device, so that the mobile device presents the left-behind reminder message.

[0111] Exemplarily, if the cloud server fails to send a left-behind reminder message to the wearable device, and if it is determined that the mobile device is not in the car, the cloud server sends a left-behind reminder message to the mobile device.

[0112] Furthermore, if the cloud server fails to send a left-behind reminder message to the wearable device, and if it is determined that the mobile device is not in the vehicle, the cloud server repeatedly sends the left-behind reminder message to the wearable device until the message is sent successfully, or directly terminates the relevant processing.

[0113] That is, in the implementation of the present application, if the mobile device is in the car and the wearable device is not in the car, the vehicle-mounted central processing system will send a message reminder of the leftovers on the wearable device through UWB, and judge the result of the sending. If the leftover reminder message is successfully sent to the wearable device, the process ends. If the leftover reminder message fails to be sent to the wearable device, the vehicle-mounted central processing system sends the leftover reminder message to the cloud TSP through the cellular network. If the message is successfully sent to the cloud TSP, the process ends, or the cloud server can send the leftover reminder message to the wearable device so that the wearable device presents the leftover reminder message. If the message fails to be sent to the cloud TSP, retry once, if it continues to fail, continue to retry until it succeeds, or stop retrying.

[0114] In this way, if the vehicle fails to send a left-behind reminder message to the wearable device, the cloud server can send a left-behind reminder message to the wearable device. If the cloud server fails to send a left-behind reminder message to the wearable device, and if the mobile device is not in the vehicle, a left-behind reminder message is sent to the mobile device, so that the left-behind reminder message of the existence of left-behind objects in the vehicle can be promptly notified to the user.

[0115] Furthermore, in another implementation of the present application, if the vehicle fails to send a left-behind reminder message to the wearable device, the left-behind reminder message can also be sent to the mobile device based on the cloud server. Figure 7 As shown, the specific steps include the following steps.

[0116] S310, when the vehicle fails to send a left-behind reminder message to the wearable device, if it is determined that the mobile device is not in the vehicle, the vehicle sends the left-behind reminder message to the cloud server.

[0117] Exemplarily, if the wearable device is not in the vehicle, the vehicle's on-board central processing system will send a message of a left-behind reminder on the wearable device via UWB and determine the result of the sending. If the left-behind reminder message is sent to the wearable device successfully, the process ends. If the left-behind reminder message is sent to the wearable device unsuccessfully, the on-board central processing system will send the left-behind reminder message to the cloud TSP via the cellular network. If the sending to the cloud TSP fails, try again. If it continues to fail, keep retrying until it succeeds, or stop retrying.

[0118] Furthermore, if the message is sent to the cloud TSP successfully, and if the mobile device is not in the vehicle, the cloud server may attempt to send a left-behind reminder message to the mobile device and determine the sending result.

[0119] S320, the cloud server sends a left-behind reminder message to the mobile device, so that the mobile device presents the left-behind reminder message.

[0120] S330, when the cloud server fails to send the left-behind reminder message to the mobile device, the cloud server sends the left-behind reminder message to the wearable device, so that the wearable device presents the left-behind reminder message.

[0121] Exemplarily, the cloud TSP first attempts to send a legacy reminder message to the mobile device and determines the sending result. If the sending of the legacy reminder message to the mobile device is successful, the relevant process is terminated. If the sending of the legacy reminder message to the mobile device fails, the cloud TSP tries to send the legacy reminder message to the wearable device again and determines the sending result. If the sending of the legacy reminder message to the wearable device is successful, the relevant process is terminated. If the sending of the legacy reminder message to the wearable device fails, try again. If it continues to fail, continue to retry until success, or stop retrying.

[0122] That is, in the implementation of the present application, if the mobile device is not in the vehicle and the wearable device is not in the vehicle, the vehicle-mounted central processing system will send a message reminder of the leftovers on the wearable device through UWB, and judge the result of the sending. If the leftover reminder message is successfully sent to the wearable device, the process ends. If the leftover reminder message fails to be sent to the wearable device, the vehicle-mounted central processing system sends the leftover reminder message to the cloud TSP through the cellular network. If the message is successfully sent to the cloud TSP, the process ends. If the message fails to be sent to the cloud TSP, try again. If it continues to fail, continue to retry until it succeeds, or stop retrying. If the message is successfully sent to the cloud TSP, you can try to send the leftover reminder message to the mobile device and judge the result of the message. If the sending of the left-behind reminder message to the mobile device is successful, the relevant process is terminated. If the sending of the left-behind reminder message to the mobile device fails, the cloud TSP tries to send the left-behind reminder message to the wearable device again and determines the sending result. If the sending of the left-behind reminder message to the wearable device is successful, the relevant process is terminated. If the sending of the left-behind reminder message to the wearable device fails, retry once. If it continues to fail, continue to retry until success, or stop retrying.

[0123] In this way, if the vehicle fails to send a left-behind reminder message to the wearable device, and if the mobile device is not in the vehicle, the cloud server can send a left-behind reminder message to the mobile device. If the cloud server fails to send a left-behind reminder message to the mobile device, it can send a left-behind reminder message to the wearable device again, so that the left-behind reminder message of the existence of left-behind objects in the vehicle can be promptly notified to the user.

[0124] Furthermore, in another implementation of the present application, if the wearable device is not in the vehicle and the vehicle fails to send a left-behind reminder message to the wearable device, if it is determined that the mobile device is not in the vehicle, a left-behind reminder message can also be sent to the mobile device.

[0125] Further, when the vehicle fails to send the left-behind reminder message to the mobile device, the vehicle sends the left-behind reminder message to the cloud server. The cloud server sends the left-behind reminder message to the mobile device so that the mobile device presents the left-behind reminder message, and when the vehicle fails to send the left-behind reminder message to the mobile device, the cloud server sends the left-behind reminder message to the wearable device so that the wearable device presents the left-behind reminder message.

[0126] In this way, if the vehicle fails to send a left-behind reminder message to the wearable device, and if the mobile device is not in the vehicle, the vehicle can send a left-behind reminder message to the mobile device. If the vehicle fails to send a left-behind reminder message to the mobile device, the cloud server will send a left-behind reminder message to the mobile device. If the cloud server fails to send a left-behind reminder message to the mobile device, the cloud server will send a left-behind reminder message to the wearable device, so that the left-behind reminder message of the existence of left-behind objects in the vehicle can be notified to the user in time.

[0127] Alternatively, when the vehicle fails to send the left-behind reminder message to the mobile device, the vehicle sends the left-behind reminder message to the cloud server. The cloud server sends the left-behind reminder message to the wearable device so that the wearable device presents the left-behind reminder message, and when the vehicle fails to send the left-behind reminder message to the wearable device, the cloud server sends the left-behind reminder message to the mobile device so that the mobile device presents the left-behind reminder message.

[0128] In this way, if the vehicle fails to send a left-behind reminder message to the wearable device, and if the mobile device is not in the vehicle, the vehicle can send a left-behind reminder message to the mobile device. If the vehicle fails to send a left-behind reminder message to the mobile device, the cloud server will send a left-behind reminder message to the wearable device. If the cloud server fails to send a left-behind reminder message to the wearable device, the cloud server will send a left-behind reminder message to the mobile device, so that the left-behind reminder message of the existence of left-behind objects in the vehicle can be notified to the user in a timely manner.

[0129] The method and system for reminding users of left-behind items in a vehicle provided by the implementation of the present application utilize UWB communication technology to monitor the relative position status (i.e., relative position relationship) between the vehicle and the mobile device and wearable device in real time. The display device of the left-behind item reminder message can be dynamically switched according to the position status of the mobile device and wearable device relative to the vehicle, thereby improving the accessibility of the left-behind item reminder message and enabling users to receive the left-behind item reminder message in a timely manner and take away the left-behind items as soon as possible.

[0130] The implementation of the present application also discloses a method for reminding a person of a left-behind object in a vehicle, which is applied to a vehicle and includes: when the vehicle determines that there is a left-behind object in the vehicle, the vehicle generates a left-behind object reminder message, and determines a first relative position relationship between the vehicle and a wearable device, and determines a second relative position relationship between the vehicle and a mobile device; the vehicle determines a presentation method of the left-behind object reminder message based on the first relative position relationship and the second relative position relationship, wherein if both the wearable device and the mobile device are in the vehicle, the vehicle presents a left-behind object reminder message; if the wearable device is in the vehicle and the mobile device is not in the vehicle, the vehicle presents a left-behind object reminder message, and / or the vehicle sends a left-behind object reminder message to the mobile device so that the mobile device presents the left-behind object reminder message; if the wearable device is not in the vehicle, the vehicle sends a left-behind object reminder message to the wearable device so that the wearable device presents the left-behind object reminder message.
