In this embodiment of the invention, the two-wheeled vehicle A is an electric two-wheeled vehicle.

[0054] In some embodiments, refer to Figure 2The two-wheeled vehicle includes a two-wheeled vehicle body 200 and a control unit 300. The control unit 300 can be set at any position on the two-wheeled vehicle body 200, such as the front of the vehicle, the middle of the two-wheeled vehicle body 200, the lower part of the two-wheeled vehicle body 200, or other suitable positions for setting the control unit 300. This embodiment of the invention does not limit this.

[0055] The two-wheeled vehicle body 200 may include components such as a frame, wheels, and a transmission assembly. The frame is used to mount and support other major components of the two-wheeled vehicle A, and the wheels are rotatably mounted on the frame. The transmission assembly is used to transmit power to drive the wheels to rotate, thereby enabling the two-wheeled vehicle A to move.

[0056] In an alternative implementation, the control unit 300 can be implemented as an ECU (Electronic Control Unit). The control unit 300 includes a memory and a processor. The processor executes a computer program, which can be written using an instruction set of architectures such as x86, Arm, RISC, MIPS, or SSE.

The control unit 300 may also include a communication module capable of communicating via at least one of wired and wireless communication. The memory stores program instructions that control the processor to perform vehicle control methods. How the instructions control the processor's operation is not described in detail here.

[0057] Two-wheeled vehicle A and server B can communicate via network D. In this embodiment of the invention, network D can be a wired network or a wireless network. In this embodiment, two-wheeled vehicle A can send location information, status information of various components of two-wheeled vehicle A, and other information related to the status of two-wheeled vehicle A to server B.

The network D on which the communication between two-wheeled vehicle A and server B, user terminal C and server B, and user terminal C and two-wheeled vehicle A are based can be the same network or different networks.

[0061] It should be understood that, despite Figure 1 Only one two-wheeled vehicle A, server B, and user terminal C are shown, but this does not mean there is a limit to their respective numbers. This system can contain multiple two-wheeled vehicles A, multiple servers B, and multiple user terminals C. Meanwhile, Figure 1 The vehicle systems shown are illustrative only and are not intended to limit the invention, its application, or its uses.

[0062] Figure 2 This is a schematic block diagram of a power battery according to an embodiment of the present invention. (Refer to...) Figure 2 Some embodiments of the present invention relate to a power battery 100 that can be used in electrically driven vehicles, particularly in electric two-wheeled vehicles, for example, in reference to... Figure 1 The two-wheeled vehicle A is described. In use, the power battery 100 is electrically connected to the drive motor on the two-wheeled vehicle A and outputs power to the drive motor so that the drive motor can drive the two-wheeled vehicle A to move.

[0063] In this embodiment, the power battery 100 is equipped with a battery motion sensor 110, which is used to detect battery motion data. The battery motion data is used to reflect the motion and / or attitude of the power battery 100. In this embodiment, there may be one or more battery motion sensors 110, and the specific type can be selected according to the detection needs.

[0064] In one embodiment, the battery motion sensor 110 includes an accelerometer, and the battery motion data includes acceleration data. Optionally, the accelerometer can be a two-axis or three-axis accelerometer, capable of detecting acceleration of the power battery 100 in at least two directions, including horizontal acceleration and vertical acceleration. The horizontal acceleration reflects the acceleration of the power battery 100 in at least one horizontal direction; the vertical acceleration reflects the acceleration of the power battery 100 in the vertical direction. Preferably, the accelerometer is a three-axis accelerometer, capable of detecting acceleration in the X, Y, and Z directions. In this embodiment, the X direction is defined as the forward / backward direction of the two-wheeled vehicle A, the Y direction is defined as the width direction (or left-right direction) of the two-wheeled vehicle A, and the Z direction is defined as the vertical direction.

[0065] In one embodiment, the battery motion sensor 110 may further include a gyroscope for detecting angular velocity, and the battery motion data may also include angular velocity data. Preferably, the gyroscope may be a three-axis gyroscope. By filtering the data detected by the accelerometer and gyroscope in a predetermined manner, the actual motion of the power battery 100 can be determined more accurately.

[0066] When abnormal changes occur in battery motion data, it can reflect abnormal motion in the power battery 100 and the two-wheeled vehicle A containing the power battery 100. For example, if the horizontal acceleration is too large or the change in horizontal acceleration within a predetermined time is too large, it indicates that the rider may be engaging in dangerous driving behavior or that the two-wheeled vehicle A has been impacted; if the vertical acceleration is large, it indicates that the two-wheeled vehicle A may have fallen from a height or tipped over. Therefore, by installing a battery motion sensor 110 in the power battery 100, the status of the power battery 100 or the two-wheeled vehicle A can be monitored.

[0067] The power battery 100 has a power management circuit board 130, which includes a power management circuit 120. The power management circuit 120 is used to perform one or more functions of the power battery 100, such as state detection, state analysis, energy control management, battery safety protection, and battery information management. In one embodiment, a battery motion sensor 110 is integrated on the power management circuit board 130, which facilitates the installation and positioning of the battery motion sensor 110 and the output of battery motion data.

[0068] Figure 3 This is a schematic diagram of the structure of a two-wheeled vehicle according to an embodiment of the present invention; Figure 4 This is a schematic block diagram of a two-wheeled vehicle according to an embodiment of the present invention. (Refer to...) Figure 3 and Figure 4 Other embodiments of the present invention also relate to a two-wheeled vehicle A, which may be a two-wheeled vehicle capable of being driven by electricity, such as an electric vehicle, and may be applied to the above-mentioned references. Figure 1 The vehicle system described. (Refer to...) Figure 3 The two-wheeled vehicle A includes a two-wheeled vehicle body 200, a power battery 100, and a control unit 300, with the power battery 100 and control unit 300 mounted on the two-wheeled vehicle body 200. The power battery 100 is electrically connected to the drive motor of the two-wheeled vehicle body 200 and can output power to the drive motor to propel the two-wheeled vehicle body 200. The control unit 300 can be used to perform one or more functions such as overall vehicle control of the two-wheeled vehicle A, data processing, and information interaction with the outside world.

[0069] The power battery 100 in this embodiment can be the same as the one referred to in the above embodiment. Figure 2 The power battery 100 is described. The power battery 100 is equipped with a battery motion sensor 110, which detects battery motion data to reflect the motion and / or attitude of the power battery 100. The battery motion sensor 110 includes an accelerometer, and in some embodiments may also include a gyroscope. Since the relative position of the power battery 100 to the two-wheeled vehicle body 200 is relatively fixed, the battery motion data detected by the battery motion sensor 110 can also reflect the motion and / or attitude of the two-wheeled vehicle A. When there are abnormal changes in the battery motion data, it can indicate that the two-wheeled vehicle A is experiencing abnormal motion. For example, when the horizontal acceleration is too large or the change in horizontal acceleration within a predetermined time is too large, it indicates that the rider may be engaging in dangerous driving behavior or that the two-wheeled vehicle A has been impacted; when the vertical acceleration is large, it indicates that the two-wheeled vehicle A may have fallen from a height or tipped over. Therefore, by setting a battery motion sensor 110 in the power battery 100, the status of the power battery 100 or the two-wheeled vehicle A can be monitored.

[0070] Reference Figure 14 The control unit 300 is electrically connected to the battery motion sensor 110 on the power battery 100 and receives battery motion data sent by the battery motion sensor 110. The control unit 300 can process and analyze the battery motion data, or send the battery motion data externally (for example, it can send the battery motion data to server B).

[0071] In this embodiment, after receiving battery motion data sent by the battery motion sensor 110, the control unit 300 processes and analyzes the battery motion data to determine whether the two-wheeled vehicle A has an abnormal motion state. When the control unit 300 determines that the two-wheeled vehicle A has an abnormal motion state, it can perform predetermined operations, such as further monitoring and analyzing the state of the two-wheeled vehicle A. Furthermore, the control unit 300 analyzes the safety risk status of the two-wheeled vehicle A in conjunction with other parameters of the two-wheeled vehicle A, and when the two-wheeled vehicle A meets the safety risk conditions, it identifies the two-wheeled vehicle A as a candidate abnormal vehicle and uploads the candidate abnormal vehicle information to the server B.

[0072] The power battery 100 includes a power management circuit board 130, which has a power management circuit 120. The power management circuit 120 is electrically connected to the control unit 300 and can interact with it. In some embodiments, a battery motion sensor 110 is integrated on the power management circuit board 130, facilitating the installation and positioning of the battery motion sensor 110 and the output of battery motion data to the control unit 300. The power management circuit board 130 is installed at a preset position in the power battery 100, and the relevant parameters for processing the battery motion data can be selected according to the installation position of the power management circuit board 130.

[0073] Reference Figure 4 The control unit 300 also includes a wireless communication circuit 320, which can communicate wirelessly with the outside world to realize information interaction between the two-wheeled vehicle A and the outside world. For example, it can realize wireless communication between the two-wheeled vehicle A and server B and / or user terminal C. In one embodiment, referring to... Figure 14 When the control unit 300 determines that two-wheeled vehicle A is a candidate abnormal vehicle, it can report the candidate abnormal vehicle information to the server B, so that the server B can further monitor and analyze the status of two-wheeled vehicle A, so that the manager of two-wheeled vehicle A can intervene in a timely manner in case of danger and ensure user safety.

[0074] In this embodiment, the power management circuit 120 can detect the battery discharge current of the power battery 100. The control unit 300 can determine the operating state of the power battery 100 based on the battery discharge current of the power battery 100. In one embodiment, referring to... Figure 14 The control unit 300 can determine whether the power battery 100 is still working normally by acquiring the battery discharge current of the power battery 100 sent by the power management circuit 120.

[0075] In some embodiments, when the control unit 300 determines that the motion state of the two-wheeled vehicle A is abnormal, it can further determine the safety state of the two-wheeled vehicle A by combining the working state of the power battery 100. In some scenarios, the output power of the two-wheeled vehicle A can be adjusted by throttle torque. In the event of a collision, the rider is more likely to release the throttle, at which point the battery discharge current of the power battery 100 will decrease. Specifically, when the battery discharge current of the power battery 100 is less than a preset current threshold, the control unit 300 can determine that the driving state of the two-wheeled vehicle is in a driving stopped state.

[0076] Furthermore, the safety risk conditions for a two-wheeled vehicle include both an abnormal motion state and a stopped driving state. When the control unit 300 determines that two-wheeled vehicle A meets the safety risk conditions, it identifies two-wheeled vehicle A as a candidate abnormal vehicle. By determining the motion state of the two-wheeled vehicle based on battery motion data and combining it with the battery discharge current of the power battery 100, it is possible to more accurately determine whether two-wheeled vehicle A has encountered a dangerous situation, reducing the possibility of misjudgment.

[0077] In some embodiments, refer to Figure 4 The control unit 300 also includes a positioning device 310, which can acquire the location information of the two-wheeled vehicle A. The control unit 300 can also transmit the location of the two-wheeled vehicle externally via a wireless communication circuit 320, for example, to a server B or a user terminal C, so that the manager or user of the two-wheeled vehicle A can know its location. When the two-wheeled vehicle A encounters a dangerous situation, it can be located based on the location obtained by the positioning device 310, and the user can be rescued.

[0078] In some embodiments of the present invention, a method for detecting abnormal states of a two-wheeled vehicle is also provided. Optionally, this method can be described with reference to the embodiments described above. Figure 3 and Figure 4 The control unit 300 of the described two-wheeled vehicle is executed. Figure 5 This is a flowchart illustrating an embodiment of a two-wheeled vehicle abnormality detection method according to the present invention. (Refer to...) Figure 5 The abnormal condition detection method for two-wheeled vehicles includes the following steps S5100 to S5300:

[0079] Step S5100: Obtain battery motion data.

[0080] Battery motion data is used to characterize the motion state of the power battery 100 of the two-wheeled vehicle A. The control unit 300 can receive battery motion data from the battery motion sensor 110 installed on the power battery 100. Specific items of the battery motion data can be selected as needed. In one embodiment, the battery motion data includes acceleration data, which includes horizontal acceleration and vertical acceleration. For example, acceleration in the X and Y horizontal directions and vertical acceleration in the Z direction can be measured using a triaxial accelerometer. In another embodiment, the battery motion data includes acceleration data and angular velocity data, where the acceleration data includes triaxial acceleration data and the angular velocity data includes triaxial angular velocity data.

[0081] Step S5200: In response to the battery motion data meeting the motion abnormality conditions, the motion state of the two-wheeled vehicle is determined to be an abnormal motion state.

[0082] Since the position of the power battery 100 on the two-wheeled vehicle A is relatively fixed, the control unit 300 can determine the motion state of the two-wheeled vehicle A based on the battery motion data. When the battery motion data meets the preset abnormal motion conditions, it indicates that the power battery 100 and the two-wheeled vehicle A may have an abnormal motion condition. At this time, the control unit 300 determines the motion state of the two-wheeled vehicle as an abnormal motion state.

[0083] The specific items of motion anomaly conditions can be determined according to the needs of the actual application scenario. In some embodiments, motion anomaly conditions include at least one of the following conditions C1-C5:

[0084] C1. The horizontal acceleration is greater than the first acceleration threshold.

[0085] C2. The rate of change of horizontal acceleration is greater than the first rate of change threshold.

[0086] C3. Vertical acceleration is greater than the second acceleration threshold.

[0087] C4. The vertical drop distance of the power battery 100 is greater than the preset distance value.

[0088] C5. The first tilt angle between the battery reference plane and the ground is less than a first angle threshold, wherein the first tilt angle between the battery reference plane and the ground is determined based on the battery motion data.

[0089] Regarding C1 or C2, when the horizontal acceleration is greater than the first acceleration threshold or the rate of change of the horizontal acceleration is greater than the first rate of change threshold, it indicates that the motion of the two-wheeled vehicle A in the horizontal direction has changed abruptly, and the two-wheeled vehicle A may be subjected to a lateral or frontal impact, etc.

[0090] Regarding C3, when the vertical acceleration is greater than the second acceleration threshold, it indicates that the two-wheeled vehicle A may have some motion in the vertical direction, and the two-wheeled vehicle A may fall or tip over.

[0091] Regarding C4, the vertical drop distance of the battery can be determined based on the vertical acceleration. When the detected vertical acceleration is downward and persists for a certain period, it indicates that the power battery 100 has fallen a certain distance vertically, possibly due to the fall or tipping over of the two-wheeled vehicle A. Therefore, a preset distance value can be set. When the vertical drop distance of the power battery 100 exceeds the preset distance value, it can be considered that the two-wheeled vehicle A has tipped over. The specific value of this preset distance value can be determined based on the installation position of the battery motion sensor 110 on the power battery 100 and the installation height of the power battery 100 on the two-wheeled vehicle A, for example, it could be 20cm, 30cm, 50cm, etc.

[0092] Regarding C5, the battery's tilt can be determined based on battery motion data, thereby determining the tilt of the two-wheeled vehicle A. One surface of the power battery 100 can be pre-defined as the battery reference surface; preferably, the left or right side of the power battery 100 can be selected as the battery reference surface. The first tilt angle between the battery reference surface and the ground can be calculated based on the battery motion data. When the first tilt angle is less than a preset first angle threshold, it indicates that the two-wheeled vehicle A may tip over. The specific size of the first tilt angle is determined based on factors such as the shape of the two-wheeled vehicle A and the installation position of the power battery 100. For example, the first tilt angle can be 20°, 25°, 30°, 32.5°, or other values. The specific calculation method for the first tilt angle can be selected from known calculation methods based on the specific items of the battery motion data. For example, when the battery motion data includes acceleration data, and the acceleration data includes acceleration in the X, Y, and Z directions, since the acceleration sensor generates a certain gravitational acceleration due to its own weight when stationary, the size of the first tilt angle can be calculated by measuring the components of gravitational acceleration in the X, Y, and Z directions. For example, when battery motion data includes both acceleration and angular velocity data, the advantages of both the accelerometer and the gyroscope in calculating the tilt angle can be combined for complementary filtering or Kalman filtering to obtain a more accurate first tilt angle.

[0093] Figure 6 This is a flowchart illustrating a method for determining the motion state of a two-wheeled vehicle as abnormal, according to an embodiment of the present invention. (Refer to...) Figure 6In some embodiments, satisfying the abnormal motion condition specifically means simultaneously satisfying conditions C1, C3, C4, and C5, or simultaneously satisfying conditions C2, C3, C4, and C5. This helps ensure that the determined result matches the actual situation of the two-wheeled vehicle A. In a feasible implementation, it is possible to first determine whether the battery motion data meets condition C1 or C2, and then determine whether the battery motion data meets conditions C3, C4, and C5 in sequence. It should be understood that... Figure 6 The order of judgment for conditions C1-C5 above is merely an illustrative example; the order of judgment for conditions C1-C5 is not limited to this. Figure 6 The order shown can be adjusted according to actual needs.

[0094] Step S5300: In response to the two-wheeled vehicle meeting the safety risk conditions, the two-wheeled vehicle is determined to be a candidate abnormal vehicle.

[0095] Among these conditions, two-wheeled vehicle A meets the safety risk criteria if its motion state is abnormal. When the two-wheeled vehicle's motion state is abnormal, it indicates that two-wheeled vehicle A may encounter collisions, falls, rollovers, tipping over, or other dangerous situations. At this time, the control unit 300 can determine that two-wheeled vehicle A is a candidate abnormal vehicle.

[0096] In some embodiments, refer to Figure 5 The abnormal condition detection method for two-wheeled vehicles also includes the following step S5400:

[0097] Step S5400: In response to determining that the two-wheeled vehicle is a candidate abnormal vehicle, send candidate abnormal vehicle information to the server.

[0098] When the control unit 300 of two-wheeled vehicle A determines that two-wheeled vehicle A is a candidate abnormal vehicle according to the predetermined rules, it can report the candidate abnormal vehicle information to server B so as to facilitate the next step of information confirmation, maintenance management and other work.

[0099] In some embodiments, the safety risk condition may also include other conditions associated with the situation of the two-wheeled vehicle A to ensure that the determined result matches the actual situation of the zero-wheeled vehicle. In some embodiments, the safety risk condition also includes the two-wheeled vehicle's driving state being a driving-stopped state. In some scenarios, the power output of the two-wheeled vehicle A is achieved by twisting the throttle. Therefore, when the two-wheeled vehicle A collides or tipes over during riding, the user usually releases the throttle, and the two-wheeled vehicle A is in a driving-stopped state. However, when the two-wheeled vehicle's motion state is abnormal, but its driving state is normal, it may be due to a malfunction of the battery motion sensor 110. By setting the safety risk condition for the two-wheeled vehicle A to include both the two-wheeled vehicle's motion state being abnormal and its driving state being a driving-stopped state, adverse interference caused by a single data source malfunction can be avoided. When both conditions are met, it can be considered that the two-wheeled vehicle A has a high probability of encountering a dangerous situation.

[0100] For example, in one embodiment, the two-wheeled vehicle abnormal state detection method further includes a step of determining the driving state of the two-wheeled vehicle A. When the two-wheeled vehicle A is an electric vehicle, the driving state of the two-wheeled vehicle can be determined based on the battery operating data of the power battery 100. Figure 7 This is a flowchart illustrating another embodiment of the abnormal state detection method for two-wheeled vehicles according to the present invention. (Refer to...) Figure 7 The two-wheeled vehicle abnormal state detection method may include steps S7100 to S7500, wherein steps S7100 to S7200 correspond to the above embodiment. Figure 5 and Figure 6 Steps S5100 to S5200 and steps S7400 to S7500 described correspond to the embodiments described above. Figure 5 Steps S5300 to S5400 are described.

[0101] Step S7300: Obtain battery operating data and determine the driving status of the two-wheeled vehicle based on the battery operating data.

[0102] Battery operating data is used to characterize the operating state of the power battery 100, and its specific items can be determined as needed. In one embodiment, the battery operating data may include the battery discharge current. When the battery discharge current is too low, it indicates that the drive motor of the two-wheeled vehicle A has stopped working. Specifically, determining the driving state of the two-wheeled vehicle based on the battery operating data includes determining that the driving state of the two-wheeled vehicle is a drive-stopped state in response to the battery discharge current being less than a preset current threshold. The current threshold can be determined according to the specific performance parameters of the power battery 100, for example, it can be 0.2A, 0.5A, 1A, or other values.

[0103] Meanwhile, in this embodiment, the two-wheeled vehicle in step S7500 meets the safety risk conditions including the two-wheeled vehicle's motion state being an abnormal motion state and the two-wheeled vehicle's driving state being a driving stop state.

[0104] In other embodiments of the present invention, a method for handling abnormal states of two-wheeled vehicles is also provided, which can be used to further process and intervene in the abnormal states reported by two-wheeled vehicle A. For example, this method can be used to perform subsequent processing after receiving candidate abnormal vehicle information determined and reported by the two-wheeled vehicle abnormal state detection method of at least some of the above embodiments, so as to ensure user safety.

[0105] Figure 8 This is a flowchart illustrating a method for handling abnormal states of a two-wheeled vehicle according to an embodiment of the present invention. Figure 8 As shown, the abnormal state handling method for the two-wheeled vehicle includes the following steps S8100 to S8300:

[0106] Step S8100: In response to receiving the alternative abnormal vehicle information, obtain safety feature data.

[0107] After receiving the alternative abnormal vehicle information sent by two-wheeled vehicle A, server B obtains safety feature data related to two-wheeled vehicle A. This safety feature data is associated with the user's behavior or status. By acquiring and analyzing the safety feature data, the user's situation regarding two-wheeled vehicle A can be further determined. The specific items of the safety feature data can be determined according to the actual application needs, for example, based on the vehicle usage process.

[0108] In some embodiments, safety feature data includes the order status of two-wheeled vehicle A. After receiving information about potential abnormal vehicles, server B obtains the order status of the corresponding two-wheeled vehicle A. Since users typically complete their ride-hailing order after using two-wheeled vehicle A normally, such as clicking the end-of-ride control on the user terminal C's ride-hailing application, etc., when two-wheeled vehicle A is identified as a potential abnormal vehicle and its order status is incomplete, it indicates a high probability that the user will have an accident and may require assistance. (Refer to...) Figure 14 The order status can be retrieved from the corresponding module on server B, or it can be obtained through other means.

[0109] In some embodiments, safety feature data includes the distance between the user and the two-wheeled vehicle A. When normal use ends, or in the event of a minor accident where the user can leave without assistance, the user will leave the two-wheeled vehicle A, and the distance between the user and the two-wheeled vehicle A will be relatively large. However, when the two-wheeled vehicle A is identified as a potential abnormal vehicle, and the distance between the user and the two-wheeled vehicle A is small, it indicates that the user has a high probability of having an accident and may require rescue. The distance between the user and the two-wheeled vehicle A can be determined by the distance between the user terminal C and the two-wheeled vehicle A. In one embodiment, obtaining safety feature data includes the following steps: obtaining the user terminal location; obtaining the two-wheeled vehicle location; and determining the distance between the user and the two-wheeled vehicle based on the user terminal location and the two-wheeled vehicle location.

[0110] Step S8200: Determine the user's security status based on the security feature data.

[0111] Based on safety feature data, the user's safety status can be determined. Specifically, in response to the safety feature data meeting the rescue conditions, server B determines the user's safety status as a candidate rescue state. The rescue conditions are determined according to the specific items in the safety feature data and may include one or more conditions. For example, when the safety feature data includes the order status of two-wheeled vehicle A, the rescue condition includes the order status being incomplete. As another example, when the safety feature data includes the distance between the user and the two-wheeled vehicle, the rescue condition includes the distance between the user and the two-wheeled vehicle being less than a first distance threshold. The first distance threshold can be determined according to the needs of the actual usage scenario, for example, it can be 0.5m, 1m, 2m, 5m, 10m, or other values.

[0112] Preferably, meeting the conditions for being awaiting rescue can involve simultaneously meeting multiple conditions. For example, it could involve simultaneously meeting two conditions: the order status is incomplete and the distance between the user and the two-wheeled vehicle A is less than a first distance threshold. This allows for a more accurate determination of the user's safety status and reduces the interference and inconvenience caused by misjudgments to the user's normal vehicle use. When the conditions for being awaiting rescue need to include multiple items, the confirmation order of these items can be arbitrarily set according to actual needs. For example, refer to... Figure 9First, the order status of two-wheeled vehicle A can be obtained (step S9101) and it can be confirmed whether the order status is incomplete (step S9102). If the order status is completed, it can be assumed that the user is not in danger, and the two-wheeled vehicle abnormal status handling process ends. If the order status is incomplete, the distance between the user and the two-wheeled vehicle can be obtained (step S9103), and the distance between the user and the two-wheeled vehicle can be compared with the first distance threshold (step S9104). When the distance between the user and the two-wheeled vehicle is less than the first distance threshold, the user's safety status is determined to be a backup rescue status (step S9105). When the distance between the user and the two-wheeled vehicle is greater than or equal to the first distance threshold, it can be assumed that the user is not in danger, and the two-wheeled vehicle abnormal status handling process ends.

[0113] Reference Figure 8 To fully ensure user safety, the abnormal status handling method for two-wheeled vehicles may also include the following steps S8300:

[0114] Step S8300: In response to determining that the user's safety status is a backup state awaiting rescue, execute the preset safety protection operation.

[0115] When a user's safety status is determined to be in a standby, awaiting rescue state, server B can verify the user's safety through one or more methods and provide safety assurance to the user if it is confirmed that the user needs rescue. For example, the preset safety assurance operation may include sending a confirmation message from server B to user terminal C or two-wheeled vehicle A, asking the user whether they need rescue.
