[0023] Overview

[0024] As described in the background technology, with the development of artificial intelligence, robot dogs are increasingly being installed in vehicles, enabling linkage between the robot dog and the vehicle and its onboard equipment. Since robot dogs are external vehicle devices, they are typically fixed to the outside of the vehicle, such as on the roof or tailgate, using external mounting devices. The external vehicle scene / conditions are complex, and there are situations where, for example, the user may not be notified if the robot dog accidentally falls while the vehicle is in motion, the robot dog may be maliciously stolen after the user leaves the vehicle, or the robot dog may fall due to a collision with the vehicle behind. These situations all pose a risk of losing the robot dog. It can be seen that robot dogs mounted on the outside of a vehicle have a higher risk of being lost, and once lost, the user will suffer significant losses. Therefore, how to reduce the risk of loss of robot dogs installed in vehicles and avoid property losses for users has become a pressing issue.

[0025] In the existing technology, the risk of loss of the robot dog is usually determined by using a camera installed on the robot dog to recognize changes in facial information, voice or location information. However, when the robot dog falls or is stolen, its components may be damaged, making it difficult to prevent the robot dog from being lost.

[0026] On this basis, the inventors discovered through further research that by obtaining the switch status signal of the external device used to fix external devices such as a robot dog on the vehicle, obtaining the vehicle status signal, and judging whether the external device is at risk of loss based on the switch status signal and the vehicle status signal, compared with using external devices that have fallen or been stolen, based on the switch status signal of the external device used to fix the external device and the status signal of the vehicle itself, it is possible to avoid the situation where the required basis for judging whether there is a risk of loss cannot be obtained due to damage to the external device, thereby timely and accurately judging whether the external device is at risk of loss, and triggering intervention measures when it is determined that the external device is at risk of loss, which can effectively reduce the risk of loss of the external device and thus ensure the property safety of the user.

[0027] Based on the above concept, an embodiment of this specification provides a method for preventing loss of an external device. The following will exemplarily describe the method for preventing loss of an external device in conjunction with the accompanying drawings.

[0028] Exemplary Methods

[0029] See also Figure 1 In an exemplary embodiment, a method for preventing loss of an external device is provided, which is applied to a vehicle. An external device is provided on the vehicle (on the outer surface), and the external device is used to fix the external device, which is, for example, a robot dog. Figure 1 As shown, the external device anti-loss method includes steps S101-S103:

[0030] S101: Acquire a switch status signal of an external device and a vehicle status signal.

[0031] There is at least one external hanging device, which is generally arranged on the roof and / or the back door, etc. In other words, the external hanging device is fixed to the roof behind the back door through the external hanging device.

[0032] The external plug-in device may be, for example, an external plug-in interface.

[0033] For example, external mounting ports are provided on the roof and tailgate. Due to the higher wind speed and greater resistance on the roof, the default mounting method for external devices is generally to mount them on the tailgate port. However, users can also choose to mount external devices on the roof port.

[0034] The external device is equipped with a switch that is used to quickly secure the external device to the vehicle. Therefore, the switch status affects whether the external device is likely to fall off, that is, there is a risk of loss.

[0035] Illustratively, the switch state includes a switch closed or a switch open.

[0036] Specifically, a switch sensor is provided on the switch of the external device, and the switch sensor is used to monitor the switch state of the external device in which it is located.

[0037] The vehicle uses a switch sensor to monitor the switch status of the external device and obtain a switch status signal. The switch status signal indicates the state of the switch, for example, whether the switch is closed or open. This allows the switch sensor to accurately obtain the switch status signal of the external device it is in, thereby accurately determining the status of the external device and whether it is at risk of being lost.

[0038] The vehicle monitors its status through built-in sensors or the vehicle's alarm system, generating a vehicle status signal. This vehicle status signal includes status signals related to whether the external device is at risk of being lost, such as a signal instructing the external device to be removed. Thus, by monitoring the vehicle's status through its own sensors or alarm system, an accurate vehicle status signal can be generated. Based on this, combining the switch status signal with the vehicle status signal can accurately determine whether the external device is at risk of being lost.

[0039] S102: Based on the switch status signal and the vehicle status signal, determine whether the external device is at risk of being lost.

[0040] For each external device, based on its switch status signal and combined with the vehicle status signal, it is determined whether the external device is at risk of being lost.

[0041] That is, for each switch status signal of the external device, the following operations are performed: based on the switch status signal and the vehicle status signal, it is determined whether the external device is at risk of being lost.

[0042] If the vehicle status signal and any switch status signal determine that the external device is at risk of loss, then the external device is determined to be at risk of loss. Correspondingly, if the vehicle status signal and all switch status signals determine that the external device is not at risk of loss, then the external device is determined to be at risk of loss.

[0043] Specifically, for the switch status signal of each external device, the switch status signal and the vehicle status signal are analyzed separately to determine the switch status of the external device represented by the switch status signal and the vehicle status represented by the vehicle status signal. Then, based on the switch status and the vehicle status, it is judged whether the external device is at risk of being lost.

[0044] S103: If there is a risk of loss of the external device, intervention measures are triggered.

[0045] Among them, intervention measures are used to reduce the risk of loss of plug-in devices (if any).

[0046] Specifically, intervention measures include issuing a prompt message, which is used to inform the vehicle owner or vehicle occupants that the external device is at risk of being lost, so that relevant measures can be taken in a timely manner, such as retrieving the dropped external device to avoid loss or checking the switch status of the external device.

[0047] Accordingly, if there is no risk of loss of the external device, no intervention measures are triggered.

[0048] In this embodiment, the vehicle obtains the switch status signal of the external device installed thereon for fixing the external device, and obtains its own status signal, namely the vehicle status signal. Based on the switch status signal of each external device and the vehicle status signal, it determines whether the external device is at risk of being lost, and automatically triggers intervention measures when the external device is at risk of being lost to reduce the risk of loss of the external device and ensure the user's property safety and information security.

[0049] In order to accurately determine whether an external device is at risk of being lost, in some embodiments, when determining whether an external device is at risk of being lost based on a switch status signal and a vehicle status signal, if the switch status signal indicates that the switch of the external device is in a first switch state, it is determined that the external device is not at risk of being lost; if the switch status signal indicates that the switch of the external device jumps from the first switch state to the second switch state, it is determined whether the external device is at risk of being lost based on whether the vehicle status signal indicates that the vehicle is in the first vehicle state; if the switch status signal indicates that the switch of the external device is in a third switch state, it is determined that the external device is at risk of being lost.

[0050] Among them, the first switch state is that there is gravity sensing, it is closed and not impacted by external force, the second switch state is that there is gravity sensing, it is open and not impacted by external force, and the third switch state is impacted by external force.

[0051] Specifically, the third switch state is when the switch is struck by an external force greater than a preset force, thereby avoiding the situation where the switch is mistakenly judged to be struck by an external force.

[0052] In addition, the first vehicle state is that the vehicle issues an external device removal instruction. The external device removal instruction is issued based on user demand and is used to instruct an occupant in the vehicle to remove an external device fixed by the external device.

[0053] Specifically, by analyzing the switch state signal and the vehicle state signal, the switch state represented by the switch state signal and the vehicle state represented by the vehicle state signal are obtained.

[0054] Or, specifically, based on the content / value of the switch state signal, the switch state represented by the switch state signal is determined, and based on the content / value of the vehicle state signal, the vehicle state represented by the vehicle state signal is determined.

[0055] If the content / value of the switch status signal is a first value, the switch status signal is determined to indicate that the switch of the external device is in the first switch state; if the content of the switch status signal jumps from the first value to the second value, the switch status signal is determined to indicate that the switch of the external device is in the second switch state; if the content of the switch status signal is a third value, the switch status signal is determined to indicate that the switch of the external device is in the third switch state. In other words, different contents of the switch status signal indicate different switch states.

[0056] More specifically, when the switch status signals of multiple external devices are obtained, if the content of the switch status signal of any external device is the third value, the obtained switch status signal is determined to indicate that the switch of the external device on which the external device is mounted is in the third switch state; if the content of the switch status signal of any external device jumps from the first value to the second value, the obtained switch status signal is determined to indicate that the switch of the external device on which the external device is mounted is in the second switch state; if the content of the switch status signals of all external devices is the first value, the obtained switch status signal is determined to indicate that the switch of the external device on which the external device is mounted is in the first switch state.

[0057] In addition, based on whether the vehicle status signal includes the first vehicle status signal, it is determined whether the vehicle status signal indicates that the vehicle is in the first vehicle state. That is, the first vehicle status signal indicates that the vehicle is in the first vehicle state. In this case, if the vehicle status signal includes the first vehicle status signal, it is determined that the vehicle status signal indicates that the vehicle is in the first vehicle state; if the vehicle status signal does not include the first vehicle status signal, it is determined that the vehicle status signal does not indicate that the vehicle is in the first vehicle state, that is, it indicates that the vehicle is not in the first vehicle state.

[0058] Generally, the value of the first vehicle state signal is the first vehicle state value. At this time, if the vehicle state signal includes a signal whose value is the first vehicle state value, it is determined that the vehicle state signal includes the first vehicle state signal.

[0059] For example, the first value, the second value, and the third value may be 0x1, 0x2, and 0x3, respectively. The first vehicle status value may be 0x10, for example.

[0060] In this embodiment, after the external device falls, the switch of the external device to which it is mounted does not sense gravity. If the external device does not fall, the switch of the external device to which it is mounted does sense gravity. In this case, if the switch is closed, the external device is unlikely to fall, but if the switch is open, the external device cannot be secured, and the external device may fall, resulting in a risk of loss. After the switch is impacted by an external force, it may be damaged regardless of whether it senses gravity or is closed, causing the external device to fall, resulting in a risk of loss. When the external device removal instruction is issued, the switch jumps from the first switch state to the second switch state, which is normal and does not pose a risk of loss. If the switch jumps from the first switch state to the second switch state when the external device removal instruction is not issued, it is abnormal and poses a risk of loss. Therefore, based on the different states of the external device switch represented by the switch state signal, including the first switch state, the second switch state, the third switch state, and the jumps between states, and comprehensively considering whether the vehicle state signal indicates that the vehicle is in the first vehicle state, that is, whether the external device removal instruction is issued, it is possible to accurately determine whether the external device is at risk of loss.

[0061] In order to ensure the safety of user property, namely external devices, in some embodiments, when intervention measures are triggered, the risk type of loss risk of the external device is determined based on the switch status signal and the vehicle status signal, and based on the risk type, the target intervention measures are triggered.

[0062] Among them, risk types include accidental drop, malicious theft and collision drop, and the target intervention measures are intervention measures corresponding to the risk types.

[0063] Specifically, while utilizing, for example, the above-mentioned embodiment, based on the switch state represented by the switch state signal and the vehicle state represented by the vehicle state signal, the risk of loss of the external device is judged, and based on the switch state represented by the switch state signal and the vehicle state represented by the vehicle state signal, the risk type of loss risk of the external device is determined.

[0064] Specifically, if the switch status signal indicates that the switch of the external device jumps from the first switch state to the second switch state, and the vehicle status signal does not indicate that the vehicle is in the first vehicle state, that is, the vehicle status signal indicates that the vehicle is not in the first vehicle state, then the risk type of loss risk of the external device is determined to be accidental falling.

[0065] That is, when the switch of the external device jumps from the first switch state to the second switch state, and the vehicle is not in the first vehicle state, it is determined that the external device is at risk of being lost due to accidental falling, or in other words, it is determined that the external device is at risk of being lost, and at the same time, it is determined that the risk type of the loss risk of the external device is accidental falling.

[0066] If the switch state signal indicates that the switch of the external device is in the third switch state, and the vehicle state signal does not indicate that the vehicle is in the second vehicle state, that is, the vehicle state signal indicates that the vehicle is not in the second vehicle state, then the risk type of loss of the external device is determined to be malicious theft. The second vehicle state is the issuance of a collision alarm signal.

[0067] That is, when the switch of the external device is in the third switch state and the vehicle is not in the second vehicle state, it is determined that the external device is at risk of loss due to malicious theft, or in other words, it is determined that the external device is at risk of loss, and at the same time, the risk type of the loss risk of the external device is determined to be malicious theft.

[0068] If the switch state signal indicates that the switch of the external device is in the third switch state, and the vehicle state signal indicates that the vehicle is in the second vehicle state, then the risk type of the loss risk of the external device is determined to be collision and drop.

[0069] That is, when the switch of the external device is in the third switch state and the vehicle status signal indicates that the vehicle is in the second vehicle state, it is determined that the external device is at risk of being lost due to collision and falling, or in other words, it is determined that the external device is at risk of being lost, and at the same time, it is determined that the risk of loss of the external device is due to collision and falling.

[0070] In addition, similar to the determination of whether the vehicle is in the first vehicle state, a determination is made as to whether the vehicle state signal indicates that the vehicle is in the second vehicle state based on whether the vehicle state signal includes the second vehicle state signal. That is, the second vehicle state signal indicates that the vehicle is in the second vehicle state. In this case, if the vehicle state signal includes the second vehicle state signal, it is determined that the vehicle state signal indicates that the vehicle is in the second vehicle state. If the vehicle state signal contains the second vehicle state signal, it is determined that the vehicle state signal indicates that the vehicle is not in the second vehicle state.

[0071] Generally, the value of the second vehicle state signal is the second vehicle state value. In this case, if the vehicle state signal includes a signal whose value is the second vehicle state value, it is determined that the vehicle state signal includes the second vehicle state signal.

[0072] Exemplarily, the second vehicle status value may be, for example, 0x11.

[0073] That is to say, if the switch status signal takes the first value, it means that the switch sensor detects that the switch has gravity sensing and the switch is in the closed state, and the switch sensor detects that the switch is not hit by an external force greater than the preset force, which means that the external device is normally hanging the robot dog.

[0074] If the switch status signal takes the second value, it means that the switch sensor detects that the switch has gravity sensing and is in the open state, and the switch sensor detects that the switch is not subjected to an external force greater than the preset force. This means that the external device is currently hanging the robot dog, but the switch is open. The robot dog may be about to be removed by the user, or the external switch is accidentally opened, causing the robot dog to fall. It is necessary to combine the vehicle itself to identify whether the vehicle has issued an opening command to the external device, that is, an instruction to normally remove the robot dog (i.e., the above-mentioned external device removal command), to determine whether the user is currently removing the robot dog normally or the robot dog is at risk of accidental loss due to a malfunction of the external device.

[0075] If the switch status signal reaches the third value, it means the switch sensor detected an external force greater than a preset force. Regardless of the external device's switch status at the time, this external force indicates an unexpected situation, potentially involving malicious theft of the robot dog or a collision with a vehicle behind. The vehicle itself must be combined with the vehicle's own collision-related signals or alarms to determine whether the robot dog was dropped due to a rear-end collision or lost due to malicious theft.

[0076] There is a corresponding relationship between risk types and intervention measures. After determining the risk type of loss risk of the plug-in device, based on the risk type and the corresponding relationship between the risk type and the intervention measures, the intervention measures corresponding to the risk type of loss risk of the plug-in device, namely the target intervention measures, are determined and triggered.

[0077] Of course, based on different actual needs, other classification standards different from the above classification standards for accidental drop, collision drop and malicious theft can be obtained.

[0078] Thus, in this embodiment, based on the switch status signal characterizing whether the switch of the external device is in the first switch state, the third switch state, or jumps from the first switch state to the second switch state, combined with the vehicle status signal characterizing whether the vehicle is in the first vehicle state or the second vehicle state, the risk type of loss risk of the external device is determined, and the target intervention measures corresponding to the risk type are triggered in a targeted manner, which can achieve targeted reduction of the loss risk of the external device, thereby effectively avoiding the loss of the external device and ensuring the property safety of the user.

[0079] In addition, in combination with the previous embodiment, based on the switch state of the switch and the vehicle state of the vehicle, when the switch is turned on and no instruction to remove the external device is issued, it is determined that the external device is at risk of being lost due to accidental falling; when there is an external force impact and no collision alarm signal is issued, it is determined that the external device is at risk of being lost due to malicious theft; when there is an external force impact and a collision alarm signal is issued, it is determined that the external device is at risk of being lost due to collision and falling, thereby achieving accurate judgment of the risk type of loss risk, thereby taking more accurate targeted intervention measures, more effectively avoiding the loss of external devices, and ensuring the user's property safety.

[0080] In order to ensure the safety of user property, that is, the safety of external devices, in some embodiments, based on the risk type, when the target intervention measures are triggered, if the risk type is collision and falling, the external device is controlled to send its location information, and a first prompt message is generated and issued based on the location information; if the risk type is malicious theft, the external device is controlled to play an alarm message, and the external device is controlled to send its location information; if the risk type is accidental falling, the external device is controlled to move with the vehicle or with the passengers in the vehicle, and the external device is controlled to generate and issue a second prompt message.

[0081] The first prompt message is used to prompt the occupant to retrieve the external device that has fallen due to a collision, and the second prompt message is used to prompt the occupant to return the external device that has fallen due to an accident. The first or second prompt message is used to prompt the occupant.

[0082] When the risk type is collision and drop, the external device is controlled to send its location information to the vehicle, and the vehicle generates and sends a first prompt message based on the location information to prompt the occupant to retrieve the external device that has fallen due to the collision.

[0083] The sending of the first prompt information specifically includes displaying the first prompt information on the vehicle's central control screen or playing the first prompt information by voice. In addition, the location information can be represented in text form or in map form.

[0084] For example, the risk type is collision and falling. Specifically, when the external device falls due to a collision with a rear vehicle, the external device sends its location information to the in-vehicle display screen or the owner's terminal and displays it. The displayed content is text, for example: "Owner, I (the external device) was hit from behind the car and my location is xx. Please pick me up."

[0085] When the risk type is malicious theft, the vehicle sends an alarm command to the external device. The external device responds to the alarm command with a voice alarm to remind the thief to return the external device and alert surrounding people. In addition, the external device responds to the alarm command to send the location information of the external device to the vehicle.

[0086] For example, when the risk type is malicious theft, the external device automatically triggers a voice alarm to warn the criminals and sends the alarm information / location information to the owner's terminal / vehicle central control.

[0087] When the risk type is malicious theft, the vehicle can also generate and send location prompt information based on the location information sent by the external device to remind the occupants in the vehicle to call the police in time or retrieve the external device by themselves.

[0088] When the risk type is accidental falling, the vehicle controls the external device to move with the vehicle or with the passenger, and controls the external device to generate and send a second prompt message to prompt the passenger to return the accidentally dropped external device to its place.

[0089] The sending of the second prompt information specifically involves the external device playing the second prompt information by voice.

[0090] For example, when the risk type is accidental falling, the vehicle sends a control instruction to the external device to control the external device to move with the vehicle or with the passengers. The external device generates and plays a second prompt message in voice. The content of the second prompt message is, for example: "Master, I (the external device) fell accidentally, please put me back in place / let me get in the car."

[0091] In this way, in this embodiment, when the risk type is collision and drop, the vehicle generates and issues a first prompt message based on the location information of the external device to prompt the occupant to retrieve the external device that has fallen due to collision. When the risk type is malicious theft, the vehicle controls the external device to directly issue an alarm and feeds back the location information to the vehicle. When the risk type is accidental drop, the external device is controlled to follow the vehicle or occupant and remind the occupant to return the external device to its place. In this way, different measures are taken to remind the occupant to retrieve the dropped external device according to different loss risks, effectively avoiding the loss of the external device and reducing the risk of loss, thereby ensuring the safety of user property.

[0092] In order to ensure the safety of user property, in some embodiments, when the risk type of loss of the external device is accidental falling, the current scenario is determined based on the vehicle status, external device status and / or environmental information, and the target intervention measures corresponding to the current scenario are triggered.

[0093] Among them, the vehicle status includes the vehicle operation status, door status and the interaction status between the vehicle and the user, the external device status includes the position relationship between the external device and the vehicle, and the environmental information includes the passenger position.

[0094] Specifically, the vehicle operating status includes driving status, parking status, and switching from driving to parking status; the door status includes left front door open, left rear door open, right front door open, and right rear door open; the interaction status between the vehicle and the user includes no interaction within a preset time period and receiving user instructions within a preset time period.

[0095] Analyze vehicle status, external device status and / or environmental information to determine the current scenario.

[0096] If the vehicle is in a driving state, the environmental information is identified to determine whether the surrounding vehicle conditions are good. If the surrounding vehicle conditions are good, the current scenario is that the vehicle is in a driving state and the surrounding vehicle conditions are good, triggering the target intervention measures corresponding to the current scenario. At this time, the target intervention measures include controlling the external device to follow the vehicle.

[0097] Specifically, when controlling the external device to follow the vehicle, the vehicle sends a follow instruction to the external device, and the external device responds to the follow instruction and follows the vehicle.

[0098] Among them, the good condition of surrounding vehicles may mean that the distance between the vehicle and surrounding vehicles exceeds the safe distance, the difference between the driving speed of surrounding vehicles and the driving speed of the vehicle is less than a preset difference, there are no obstacles, etc.

[0099] This is different from directly controlling the external device to follow the vehicle in the current scenario where the vehicle is in motion and surrounding traffic is in good condition. Before controlling the external device to follow the vehicle, a third prompt message can be generated and displayed on the vehicle's central control display to inform the vehicle's occupants that the external device is missing. The external device can then be controlled to follow the vehicle in response to user operation. Alternatively, if the user does not operate, the third prompt message will be displayed for a period of time, and the vehicle will automatically send a follow command to the external device to control the external device to follow the vehicle. In other words, the target intervention measure also includes notifying the vehicle's occupants that the external device is missing.

[0100] If the vehicle's operating state switches from driving to parking, the current scenario is determined to be driving to parking, triggering a target intervention measure corresponding to the current scenario. In this case, the target intervention measure includes controlling the external device to generate and issue a second prompt message. In this case, the second prompt message may be, for example, "Owner, please return me (the external device) to its original position."

[0101] Alternatively, the targeted intervention measure may include controlling the vehicle to a safe door position. The safe door position is defined as a position where the vehicle door, when opened, will not collide with the external device. The door here generally refers to the driver's door. The second prompt message may be, for example, "Owner, please let me (external device) in the vehicle."

[0102] If the door status is "target door open," the current scenario is determined to be "target door open," where the target door is any door on the vehicle. The target intervention action corresponding to the current scenario is triggered. In this case, the target intervention action includes controlling the external device to move to the target door and automatically enter the vehicle.

[0103] Specifically, the vehicle sends an automatic boarding instruction to the external device, where the automatic boarding instruction includes the location of a target door, and is used to instruct the external device to move to the target door and automatically board the vehicle.

[0104] In addition, if the door status is that the target door is open, the environmental information is identified to determine whether the occupant in the vehicle has gotten off. If the occupant in the vehicle does not get off, the current scene is determined to be that the target door is open and the occupant expects the external device to automatically get on the vehicle, triggering the target intervention measures corresponding to the current scene. At this time, the target intervention measures include controlling the external device to move to the target door and automatically get on the vehicle; if the occupant in the vehicle gets off, the current scene is determined to be that the target door is open and the occupant gets off the vehicle, triggering the target intervention measures corresponding to the scene. At this time, the target intervention measures include controlling the external device to move to the target door and issuing a second prompt message.

[0105] If the vehicle is in the driving state, the environmental information is identified and it is determined that the surrounding vehicle conditions are poor and parking is inconvenient. The current scenario is determined to be that the vehicle is in the driving state and cannot be parked, and the target intervention measures corresponding to the current scenario are triggered. At this time, the target intervention measures include informing the external device of the current scenario and controlling the external device to move with the vehicle within a safe area.

[0106] The vehicle is in a parked state. Based on whether the door is unlocked and by identifying environmental information, it is determined whether the occupants are around the vehicle, and then the current scene is determined.

[0107] If the current scenario is that the vehicle is parked, the doors are unlocked, and the occupants are located around the vehicle, the target intervention measures corresponding to the current scenario are triggered. At this time, the target intervention measures include controlling the external device to move to the occupants and issuing a second prompt message.

[0108] If the current scenario is that the vehicle is parked, the doors are unlocked and the occupants are not around the vehicle (the occupants are inside the vehicle), a third prompt message is issued. The third prompt message is displayed on the vehicle's central control display screen to inform the occupants inside the vehicle that the external device is lost, or is displayed on the owner's terminal to inform the owner that the external device is lost.

[0109] Among them, the passenger may refer to the vehicle owner.

[0110] If there is no interaction between the vehicle and the user within a preset time period, and the external device is not located on the vehicle, and the vehicle is unlocked, it is determined that the current scenario is that the occupants are not in the vehicle for a short period of time. At this time, the target intervention measures corresponding to the current scenario are triggered, including controlling the external device to be located in a safe position around the vehicle.

[0111] If there's no interaction between the vehicle and the user for a preset period of time, and the external device isn't on the vehicle, the vehicle is locked, and the scenario is determined to be an extended absence or storage in a parking space / garage. The targeted intervention corresponding to that scenario is triggered, including controlling the vehicle to move underneath it and, upon receiving the unlock command, to one side of the vehicle, such as the driver's door, to issue a second prompt. This conceals the external device, preventing it from being removed by passersby and potentially lost.

[0112] For vehicles with lower chassis, the targeted intervention measures also include linking the vehicle suspension structure to increase the vehicle chassis height.

[0113] If the vehicle is in the ignition state and the external device is located under the vehicle, the current scenario is determined to be the vehicle ignition on and the external device is located under the vehicle. At this time, the target intervention measures corresponding to the current scenario are triggered, including prohibiting the vehicle from moving and issuing a fourth prompt message. This fourth prompt message is used to prompt the user to quickly retrieve the external device located under the vehicle before starting the vehicle. This can prevent damage to the external device.

[0114] Thus, in this embodiment, the current scenario is determined for different vehicle states, external device states and / or environmental information, and target intervention measures corresponding to the current scenario are triggered. In this way, different target intervention measures can be taken for different scenarios under the risk of accidental falling to control the external device to automatically return to the vehicle, remind passengers to put the external device back in place, etc., which can effectively avoid the loss of external devices in various scenarios, reduce the risk of loss, and thus ensure the safety of user property.

[0115] For example, if the external device is a robot dog and the switch status signal has the values of the first value 0x1, the second value 0x2 and the third value 0x3, the external device anti-loss process can be as follows: Figure 2As shown, the switch sensors of the two external devices of the robot dog monitor their switch status, and send their real-time monitoring results, including A signal and B signal (i.e., the above-mentioned switch status signals), to the vehicle system. If either A or B signal is 0x3 and the vehicle has received a rear vehicle collision alarm (i.e., the above-mentioned collision alarm signal), the robot dog's rear vehicle collision and falling risk (i.e., the external device is at risk of being lost due to collision and falling) active intervention measures (i.e., the above-mentioned intervention measures) are automatically triggered; if either A or B signal is 0x3 but the vehicle has not received a rear vehicle collision alarm, the robot dog's malicious theft risk (i.e., the external device is at risk of being lost due to collision and falling) is automatically triggered. If neither the A nor the B signals changes from 0x1 to 0x2, it is determined that the robot dog remains in the suspended state (i.e., there is no risk of loss of the external device), and no active intervention is performed; if either the A or B signals changes from 0x1 to 0x2, it is determined whether the vehicle issues an instruction to remove the robot dog (i.e., the above-mentioned instruction to remove the external device). If an instruction to remove the robot dog is issued, the user takes away the robot dog, and no intervention is performed. If no instruction to remove the robot dog is issued, the active intervention measure for the risk of accidental falling of the robot dog (i.e., there is a risk of loss of the external device due to accidental falling) is automatically triggered.
