The system may include multiple electric vehicles 100, multiple servers 200, and multiple user terminals 300. Figure 1 The shared vehicle system shown is illustrative only and is not intended to limit the invention, its application, or uses.

[0051] Hereinafter, various embodiments according to the present invention will be described with reference to the accompanying drawings.

[0052] Figure 2 is a schematic structural diagram of an electric vehicle according to an embodiment of the present invention, Figure 3 1 is a schematic block diagram of the structure of an electric vehicle 100 according to an embodiment of the present invention. Figure 2 and Figure 3In the embodiment of the present invention, the electric vehicle 100 includes a vehicle body 110 and a power mechanism 150. Figure 2 The dotted box 150 in the figure schematically shows the approximate position of the power mechanism 150 on the electric vehicle 100. The vehicle body 110 may include the main structural components of the electric vehicle 100, such as a frame, wheels, a transmission assembly, a seat bucket 111 and a seat cushion 112. The frame is used to install and support other main components of the electric vehicle 100, and the wheels are rotatably arranged on the frame. The seat bucket 111 is installed at the rear of the frame, and a seat cushion 112 is provided on the seat bucket 111 for the rider of the electric vehicle 100 to sit on. The transmission assembly is connected to the power mechanism 150, and the power mechanism 150 generates power and transmits power through the transmission assembly to drive the wheels to rotate, so that the electric vehicle 100 can move. The power mechanism 150 may include a drive motor and other devices and components for providing power for the travel of the electric vehicle 100.

[0053] In the embodiment of the present invention, the electric vehicle 100 further includes a rear armrest 120 . Figure 4 1 is a schematic diagram of the installation position of the rear armrest 120 on the electric vehicle 100 according to an embodiment of the present invention. Figure 5 is a schematic diagram of the structure of a rear armrest 120 according to an embodiment of the present invention, referring to Figure 2 , Figure 4 and Figure 5 The rear armrest 120 is provided at the rear of the seat bucket 111 and is installed near the rear side of the seat cushion 112. For example, it may have a certain gap with the rear edge of the seat cushion 112 and protrude from the upper surface of the seat cushion 112. The rear armrest 120 includes an armrest body, and the armrest body has a first mounting structure 123. The first mounting structure 123 is used to connect with the vehicle body 110 of the electric vehicle 100. The specific form of the first mounting structure 123 can be selected according to the structure of the vehicle body 110. For example, the first mounting structure 123 may include a mounting hole, and the armrest body may fix the first mounting structure 123 to the frame of the vehicle body 110 by bolt fastening. In some embodiments, the armrest body includes a cross bar 121 and at least one connecting rod 122. The first mounting structure 123 is provided at one end of the connecting rod 122, and the other end of the connecting rod 122 is connected to the cross bar 121. The position and number of the connecting rod 122 can be selected as needed. For example, the number of the connecting rod 122 can be one and the connecting rod 122 is connected to the middle part of the cross bar 121 (not shown); Figure 5, there are two connecting rods 122, and the two connecting rods 122 are respectively arranged at the two ends of the cross bar 121. The cross bar 121 of the rear armrest 120 can be used to stop the rider of the electric vehicle 100 sitting on the seat cushion 112, so as to prevent the rider from detaching from the seat cushion 112 from the rear side of the seat cushion 112 and causing danger; in addition, the rear armrest 120 can also play an auxiliary effect when placing or carrying the electric vehicle 100. For example, when the electric vehicle 100 is parked, the placement angle of the electric vehicle 100 can be adjusted by lifting the rear armrest 120 and moving the vehicle body 110.

[0054] Refer again Figure 2 and Figure 3 The electric vehicle 100 further includes a main control device 130. The main control device 130 is disposed in the vehicle body 110 and can be disposed at any position of the vehicle body 110 as required, such as the front of the vehicle (for example, see Figure 2 The main control device 130 is electrically connected to the power mechanism 150. The main control device 130 is used to control the electric vehicle 100, for example, it can be used to adjust and control the output power of the power mechanism 150 or to manage and control the electric devices such as the speaker 140 and lights on the electric vehicle 100.

[0055] In an optional implementation, the main control device 130 can be implemented by an electronic control unit (ECU). The main control device 130 includes a memory and a processor, and the processor is used to execute a computer program, which can be written in an instruction set of an architecture such as x86, Arm, RISC, MIPS, SSE, etc. The memory includes, for example, ROM (read-only memory), RAM (random access memory), a non-volatile memory such as a hard disk, etc. The control unit may also include a communication module, which can communicate through at least one of wired communication and wireless communication. The memory is used to store program instructions, which are used to control the processor to operate to execute a control method for the electric vehicle 100. How the instructions control the processor to operate is not described in detail here.

[0056] The main control device 130 includes a wireless communication module. In some scenarios, the main control device 130 can establish a wireless communication connection with the server 200 through the wireless communication module (for example, it can be connected through the cellular network 400) to realize information interaction between the electric vehicle 100 and the server 200. In some scenarios, the main control device 130 can establish a wireless communication connection with the user terminal 300 through the wireless communication module to realize information interaction between the electric vehicle 100 and the user terminal 300. Optionally, the wireless communication module of the main control device 130 includes a short-range wireless communication module. When the distance between the user terminal 300 and the electric vehicle 100 is less than the communication distance of the short-range wireless communication module, the user terminal 300 and the wireless communication module of the main control device 130 can be paired based on a predetermined method as needed. After the pairing is successful, the wireless communication module of the main control device 130 can exchange information with the paired user terminal 300.

[0057] In some application scenarios of shared electric vehicles 100, in order to ensure the safety of the vehicle, the electric vehicle 100 allows one person to ride and needs to avoid the driver of the electric vehicle 100 from carrying other people as much as possible. In an embodiment of the present invention, the main control device 130 is also used to implement supervision of the riding safety of the electric vehicle 100, and the supervision of the riding safety of the electric vehicle 100 includes the detection and control of the number of people carried by the electric vehicle 100. The main control device 130 is configured to determine the passenger status of the electric vehicle 100, and when it is determined that the passenger status of the electric vehicle 100 is a multi-person riding status, it executes a preset anti-multi-person riding operation. In an embodiment of the present invention, "multi-person riding" means that two or more people ride the same electric vehicle 100.

[0058] The anti-multi-riding operation performed by the main control device 130 may include one or more preset operations, for example, it may include controlling the sound and light devices on the electric vehicle 100 to remind the rider, limiting the power output of the electric vehicle 100, locking the electric vehicle 100, etc., which can restrict the rider from using the electric vehicle 100 normally, can serve as a reminder to the rider, or other operations that are conducive to managing the passenger status of the electric vehicle 100. One or more operations.

[0059] In one implementation, referring to Figure 3The electric vehicle 100 includes a speaker 140, which is disposed on the vehicle body 110 and is electrically connected to the main control device 130. The speaker 140 can be disposed at the front, rear or other position of the vehicle body 110 that can facilitate the transmission of sound information to the user of the electric vehicle 100. The main control device 130 performs a preset anti-multi-riding operation including controlling the speaker 140 to play an overload voice prompt message. The overload voice prompt message can be pre-stored in a memory electrically connected to the drive circuit of the speaker 140, and the specific content of the overload voice prompt message can be selected according to the needs of the actual application scenario, so as to achieve an overload reminder and dissuasion effect for the rider of the electric vehicle 100. For example, the overload voice prompt message can be "You are overloaded, this vehicle is only for single-person riding" or other terms.

[0060] In another implementation, the electric vehicle 100 includes a display device (not shown), for example, a display screen can be provided at the front of the vehicle. The main control device 130 may control the display device to display overload graphic and text prompt information when executing the preset multi-riding prevention operation. The overload graphic and text prompt information may include a pattern, text, or a combination thereof that can serve to remind and dissuade the riders of the electric vehicle 100 from overloading, and the specific form may be selected according to actual needs.

[0061] In another implementation, the main control device 130 controls the output state of the power mechanism 150 according to the passenger state of the electric vehicle 100, and the main control device 130 performs the preset anti-multi-riding operation, which may include limiting the output power of the power mechanism 150. For example, when the passenger state of the electric vehicle 100 is not a multi-riding state (for example, a single-riding state), the maximum output power of the power mechanism 150 controlled by the main control device 130 can be determined according to relevant traffic regulations. When the passenger state of the electric vehicle 100 is a single-riding state, the riding speed corresponding to the maximum output power of the power mechanism 150 is a higher value (for example, 25 km / h). When it is determined that the passenger state of the electric vehicle 100 is a multi-riding state, the main control device 130 controls the power mechanism 150 to limit the maximum output power of the power mechanism 150 to a lower value, thereby limiting the maximum riding speed of the two-wheeled vehicle to a lower value (for example, 15 km / h) lower than the riding speed in the normal riding state to reduce the risk of accidents when the user rides, and the slower riding speed can prompt the rider to consider giving up the behavior of riding the electric vehicle 100 with multiple people. Alternatively, when it is determined that the electric vehicle 100 is in a multi-person riding state, the main control device 130 controls the output power of the power mechanism 150 to be zero, so as to avoid the situation where multiple people ride the electric vehicle 100 .

[0062] In another implementation, with the user's permission in advance, the main control device 130 can be paired with the user terminal 300 under certain conditions and establish a wireless communication connection. The main control device 130 may perform a preset anti-multi-riding operation, including sending multi-riding status information to the paired user terminal 300, and the vehicle application client on the user terminal 300 may enable the user terminal 300 to play an overload voice prompt message, or enable the display of the user terminal 300 to display an overload graphic prompt message under the interface of the vehicle application client, so as to provide a prompt effect to the rider of the electric vehicle 100.

[0063] In one implementation, when the main control device 130 determines that the passenger state of the electric vehicle 100 is a multi-person riding state, the multi-person riding state information can be uploaded to the server 200, so that the server 200 can perform corresponding processing according to the multi-person riding state information in accordance with a preset processing strategy. For example, after receiving the multi-person riding state information, the server 200 can create a work order to further monitor or analyze the state of the corresponding electric vehicle 100, and take intervention measures to dissuade riders from performing multi-person riding behavior when necessary.

[0064] In some embodiments, the processing of the detection signal can also be implemented by the server 200. The main control device 130 establishes a wireless communication connection with the server 200, and sends the detection signal received from the rear armrest 120 to the server 200. The server 200 analyzes the detection signal according to a pre-set rule, determines the passenger state information of the electric vehicle 100 based on the detection signal alone, or determines the passenger state information of the electric vehicle 100 by combining the detection signal with other information related to the passenger state of the electric vehicle 100. The passenger state information can reflect the possible passenger state of the electric vehicle 100. The main control device 130 receives the passenger state information from the server 200, and determines the passenger state of the electric vehicle 100 according to the content of the passenger state information. In this way, the processing of the detection signal and the judgment process of the passenger state of the electric vehicle 100 can be partially shared by the server 200, which is conducive to reducing the data processing amount of the main control device 130. That is, in this case, the process from the detection signal to the determination result of the passenger state of the electric vehicle 100 is realized by the cooperation of the electric vehicle 100 and the server 200.

[0065] The passenger state of the electric vehicle 100 can be determined based on signals from one or more collection devices installed on the electric vehicle 100 that can collect data related to the passenger state of the electric vehicle 100. The embodiment of the present invention provides a rear armrest 120 that can detect data related to the passenger state of the electric vehicle 100.

[0066] Reference Figure 4 and Figure 6In this embodiment, a detection component 126 is provided on the rear armrest 120, and the detection component 126 is provided on the armrest body. The detection component 126 is used to collect data related to the passenger state of the electric vehicle 100 and generate a detection signal, and the passenger state of the electric vehicle 100 can be determined according to the detection signal of the detection component 126. Preferably, the detection component 126 is provided at the cross bar 121 of the armrest body, and the cross bar 121 is opposite to the area for passengers to sit on the electric vehicle 100. The detection component 126 is provided at the cross bar 121, so that the data related to the passenger state of the electric vehicle 100 can be collected more accurately.

[0067] In one embodiment, the detection component 126 may include a distance sensor, and the detection method of the distance sensor may be, for example, infrared detection, microwave detection, millimeter wave radar detection, etc. Since the length of the seat cushion 112 is limited, when two people are riding on the seat cushion 112, the distance between the human body and the detection component 126 of the rear armrest 120 is shorter than the distance between the human body and the detection component 126 when only one person is riding. Therefore, according to the distance value between the human body and the rear armrest 120 detected by the distance sensor, or whether the distance sensor with a predetermined detection distance is triggered, it can be determined whether the passenger state of the electric vehicle 100 is a multi-person riding state. For example, a distance threshold value may be pre-set, and the detection signal of the detection component 126 represents the distance value between the human body and the rear armrest 120. When the distance value between the human body and the rear armrest 120 is less than the distance threshold value, it can be determined that the passenger state of the electric vehicle 100 is a multi-person riding state, and the main control device 130 can perform a preset multi-person riding prevention operation.

[0068] In one embodiment, the detection component 126 may include a pressure sensor, and a pressure signal is generated when the pressure sensor is triggered, and the detection signal of the detection component 126 includes the pressure signal. The specific type of the pressure sensor may include one or more of a strain gauge pressure sensor, a capacitive pressure sensor, a piezoresistive pressure sensor, a piezoelectric pressure sensor, or other pressure sensors suitable for being arranged on the rear armrest 120. The length of the seat cushion 112 of the electric vehicle 100 is set to allow one person to ride. When a person sits on the seat cushion 112 and rides the electric vehicle 100, there is usually a certain distance between the human body and the rear armrest 120, and the pressure sensor will not be triggered; even if the pressure sensor is triggered due to the rider's relatively strong body or his clothes, backpack and other items touch the rear armrest 120, the pressure value represented by the pressure signal is also small, or the pressure value represented by the pressure signal will fluctuate greatly due to the adjustment of the rider's posture. When there are two or more passengers on the seat cushion 112, due to the length limitation of the seat cushion 112, the passengers sitting at the rear will squeeze the rear armrest 120, and the pressure sensor will be triggered to generate a pressure signal. In addition, when there are multiple passengers, the pressure exerted by the human body on the rear armrest 120 is relatively large. There is a correlation between the pressure signal and the passenger status of the electric vehicle 100, so the passenger status of the electric vehicle 100 can be determined based on the pressure signal.

[0069] When determining the passenger state of the electric vehicle 100, at least one of the value of the pressure value represented by the pressure signal and the change of the pressure value can be considered. For example, the pressure value represented by the pressure signal can be compared with the preset pressure threshold, and the passenger state of the electric vehicle 100 can be determined according to the comparison result. The preset pressure threshold is a specific value that can be determined by testing or simulation according to the actual situation. When the pressure applied to the pressure sensor is greater than the preset pressure threshold, it indicates that the number of passengers on the seat cushion 112 is two or more. In order to reduce the probability of misjudgment, the determination of the passenger state of the electric vehicle 100 can also consider the change of the pressure value represented by the pressure signal. Specifically, in the process of the second rider sitting on the seat cushion 112, the pressure value represented by the pressure signal will usually increase from zero or a smaller value to a larger value (for example, a value greater than the aforementioned pressure threshold) within a certain time range, and then tend to stabilize (that is, the amplitude of the fluctuation is within a smaller range). If the pressure sensor is triggered by a backpack or clothing of a single rider, even if the pressure value represented by the pressure signal at a certain time point is greater than the pressure threshold, the pressure value represented by the pressure signal may continue to fluctuate for a period of time, or drop to a smaller value (for example, to zero) at a certain time point due to factors such as the rider's posture adjustment; and due to the length limitation of the seat cushion 112, when more than two riders sit on the seat cushion 112, even if the riders adjust their postures, the pressure value represented by the pressure signal usually will not drop to zero or a smaller value close to zero. It can be seen that by comprehensively considering the changes in the pressure value represented by the pressure signal and the comparison result with the preset pressure threshold, the passenger status of the electric vehicle 100 can be effectively and accurately determined.

[0070] Figure 7 FIG. 1 is a schematic diagram showing the relationship between the rear armrest 120 installed on the electric vehicle 100 and other devices on the electric vehicle 100. Figure 6 and Figure 7 The rear armrest 120 further includes a communication circuit 127, which is disposed in the armrest body and electrically connected to the detection component 126. The communication circuit 127 establishes a communication connection with the main control device 130, and sends the detection signal generated by the detection component 126 to the main control device 130. The communication connection between the communication circuit 127 and the main control device 130 can be a wired communication connection, or can be a wireless communication connection. Figure 7Preferably, the communication circuit 127 is a wireless communication circuit 127, and a communication connection is established between the communication circuit 127 and the main control device 130 by wireless means for signal transmission. This setting method can save the wiring between the rear armrest 120 and the main control device 130, reducing the difficulty of installation and maintenance of the rear armrest 120; and can make the rear armrest 120 have good universal applicability, which is convenient for modifying the existing electric vehicle 100 that does not have a multi-person riding detection function. When modifying the existing electric vehicle 100, the existing rear armrest 120 without the detection component 126 on the electric vehicle 100 is replaced with the rear armrest 120 of the embodiment of the present invention, without considering the wiring problem between the rear armrest 120 and the main control device 130. The wireless communication method adopted by the communication circuit 127 can be selected according to the needs of the actual application, for example, the wireless communication method of the communication circuit 127 can be selected according to the installation position of the main control device 130 and the type of wireless communication module of the main control device 130.

[0071] Reference Figure 6 and Figure 7 , the rear armrest 120 also includes a power supply 128. The power supply 128 is disposed in the armrest body and is electrically connected to the detection component 126 and the communication circuit 127 to supply power to the detection component 126 and the communication circuit 127. The rear armrest 120 does not need to lead out the power supply 128 line, which facilitates the installation of the rear armrest 120 and the vehicle body 110. In the present embodiment, the communication circuit 127 includes a Bluetooth communication circuit 127. Preferably, the Bluetooth communication circuit 127 adopts Bluetooth Low Energy (BLE) technology, which is beneficial to reduce energy consumption, extend the battery life of the power supply 128, and reduce the maintenance frequency of the rear armrest 120. Preferably, the power supply 128 is disposed in the rear armrest 120 in a manner that it can be removed from the armrest body. For example, referring to Figure 5 The armrest body has an installation cavity, a power source 128 is disposed in the installation cavity, the installation cavity has an opening 124 on the surface of the armrest body for the power source 128 to pass through, and the armrest body also has a cover plate 125, which is detachably disposed on the opening 124 to achieve the closing and opening of the opening 124. The communication circuit 127 can also be disposed in the installation cavity, and the armrest body can protect the communication circuit 127.

[0072] In the above embodiment of the present invention, a detection unit is arranged in the rear armrest 120 to detect and generate a detection signal related to the passenger state of the electric vehicle 100. The detection signal can be used to determine the passenger state of the electric vehicle 100. When the main control device 130 of the electric vehicle 100 determines that the passenger state of the electric vehicle 100 is a multi-person riding state, a preset multi-person riding prevention operation is performed to achieve persuasion or prevention of multi-person riding on the same electric vehicle, which is conducive to ensuring traffic order and traffic safety. Compared with the method of arranging a weight sensor in the seat cushion 112 or the shock absorber to detect weight, the design structure of arranging the detection unit in the rear armrest 120 is simple and reliable, which is conducive to reducing costs. At the same time, it is convenient to modify the existing electric vehicle 100 that does not have the multi-person riding detection capability, and the subsequent maintenance is relatively simple, which is suitable for universal application.

[0073] The embodiment of the present invention also provides a riding safety supervision method. In some application scenarios, the execution subject of the method can be the above reference Figures 1 to 7 The main control device 130 in the electric vehicle 100 is described.

[0074] Figure 8 FIG. 1 is a flow chart of a riding safety supervision method according to an embodiment of the present invention. Figure 8 The riding safety supervision method of the embodiment of the present invention includes the following steps S810 to S830:

[0075] Step S810: Acquire a detection signal of a detection component disposed on a rear armrest of the electric vehicle.

[0076] The generation of the detection signal can be realized by the detection component 126 in the rear armrest 120 in the above embodiment. The detection signal is related to the passenger state of the electric vehicle 100, and the specific type of the detection signal is determined according to the type of the detection component 126. For example, when the detection component 126 includes a pressure sensor, the detection signal includes a pressure signal.

[0077] Step S820: Determine the passenger status of the electric vehicle.

[0078] The passenger state of the electric vehicle 100 is determined directly or indirectly according to the detection signal. The correlation between the determination result of the passenger state of the electric vehicle 100 and the detection signal can be selected according to the specific setting of the detection component 126 of the rear armrest 120. For example, when the detection component 126 includes a distance sensor and the detection signal includes a distance signal, the passenger state of the electric vehicle 100 can be determined as a multi-person riding state when the distance value between the human body and the rear armrest 120 represented by the detection signal of the detection component 126 is less than a preset distance threshold. For another example, when the detection component 126 includes a pressure sensor and the detection signal includes a pressure signal, the passenger state of the electric vehicle 100 can be determined as a multi-person riding state when the pressure value represented by the pressure signal is greater than a preset pressure threshold. In addition, the passenger state of the electric vehicle 100 can also be determined by comprehensively considering the detection signal and other information related to the passenger state of the electric vehicle 100. For example, when a camera is installed on the electric vehicle 100, the passenger state of the electric vehicle 100 can be determined by comprehensively judging the detection signal of the detection component 126 set on the rear armrest 120 of the electric vehicle 100 and the image signal collected by the camera.

[0079] In some implementations, the process of determining the passenger status of the electric vehicle 100 according to the detection signal is completed solely by the main control device 130 of the electric vehicle 100.

[0080] In other embodiments, the processing of the detection signal can also be assisted by the server 200. In this embodiment, between steps S810 and S820, there is also a step of sending the detection signal to the server 200, and a step of receiving the manned state information returned by the server 200 according to the detection signal. The server 200 can analyze the detection signal according to a pre-set rule, and determine the manned state information of the electric vehicle 100 based on the detection signal alone, or after combining the detection signal with other information related to the manned state of the electric vehicle 100, the manned state information can reflect the possible manned state of the electric vehicle 100. The main control device 130 receives the manned state information from the server 200, and determines the manned state of the electric vehicle 100 according to the content of the manned state information. In this way, the processing of the detection signal and the judgment process of the manned state of the electric vehicle 100 can be partially shared by the server 200, which is conducive to reducing the data processing amount of the main control device 130. In this embodiment, the main control device 130 determines the passenger status of the electric vehicle 100 based on the passenger status information, that is, the main control device 130 determines the passenger status of the electric vehicle 100 indirectly based on the detection signal.

[0081] Step S830: When it is determined that the passenger state of the electric vehicle 100 is a multi-person riding state, a preset multi-person riding prevention operation is executed.

[0082] The multi-riding prevention operation may include one or more actions that can be performed by the main control device 130 to dissuade or hinder the behavior of multiple people riding the same electric vehicle 100. For example, according to the specific configuration of the electric vehicle 100, the preset multi-riding prevention operation may include at least one of the following items C1 to C4:

[0083] C1. Control the speaker of the electric vehicle to play the overload voice prompt information.

[0084] In some application scenarios, refer to Figure 3 The electric vehicle 100 includes a speaker 140, and the rider of the electric vehicle 100 can be reminded by controlling the speaker 140 to play an overload voice prompt message. The overload voice prompt message can be pre-stored in a memory electrically connected to the drive circuit of the speaker 140, and the specific content of the overload voice prompt message can be selected according to the needs of the actual application scenario, so as to achieve an overload reminder and dissuasion effect for the rider of the electric vehicle 100. For example, the overload voice prompt message can be "You are overloaded, this vehicle is only for one person to ride" or other terms.

[0085] C2. Limit the output power of the power mechanism of the electric vehicle.

[0086] Reference Figure 2 and Figure 3 The electric vehicle 100 has a power mechanism 150. In some application scenarios, the output power of the power mechanism 150 can be limited to prevent multiple people from riding. For example, when the passenger state of the electric vehicle 100 is not a multi-person riding state (for example, a single-person riding state), the maximum output power of the power mechanism 150 controlled by the main control device 130 can be determined according to relevant traffic regulations. When the passenger state of the electric vehicle 100 is a single-person riding state, the riding speed corresponding to the maximum output power of the power mechanism 150 is a higher value (for example, 25 km / h). When it is determined that the passenger state of the electric vehicle 100 is a multi-person riding state, the main control device 130 controls the power mechanism 150 to limit the maximum output power of the power mechanism 150 to a lower value, thereby limiting the maximum riding speed of the two-wheeled vehicle to a lower value (for example, 15 km / h) lower than the riding speed in the normal riding state to reduce the risk of accidents when the user rides. At the same time, the slower riding speed can prompt the rider to consider giving up the behavior of multiple people riding the electric vehicle 100. Alternatively, when it is determined that the electric vehicle 100 is in a multi-person riding state, the main control device 130 controls the output power of the power mechanism 150 to be zero, so as to avoid the situation where multiple people ride the electric vehicle 100 .

[0087] C3. Send multi-person riding status information to the server.

[0088] Reference Figure 1, the main control device 130 can establish a communication connection with the server 200. In some application scenarios, when it is determined that the passenger state of the electric vehicle 100 is a multi-person riding state, the main control device 130 can upload the multi-person riding state information to the server 200, so that the server 200 can perform corresponding processing according to the multi-person riding state information according to a preset processing strategy.

[0089] C4. Sending multi-person riding status information to paired user terminals.

[0090] In some application scenarios, with the user's permission in advance, the main control device 130 can be paired with the user terminal 300 under certain conditions and establish a wireless communication connection. The main control device 130 may perform a preset anti-multi-riding operation, including sending multi-riding status information to the paired user terminal 300, and the vehicle application client on the user terminal 300 may enable the user terminal 300 to play an overload voice prompt message, or enable the display of the user terminal 300 to display an overload graphic prompt message under the interface of the vehicle application client, so as to provide a prompt effect to the rider of the electric vehicle 100.

[0091] With reference to the description of the above embodiments of the electric vehicle 100 and the rear armrest 120 , in some embodiments, the detection component 126 of the rear armrest 120 includes a pressure sensor, and the detection signal includes a pressure signal. Fig. 9 FIG. 1 is a flow chart of a riding safety supervision method according to another embodiment of the present invention, wherein the passenger status of the electric vehicle 100 can be determined based on the pressure signal. Fig. 9 The riding safety supervision method of this embodiment includes the following steps S910 to S950.

[0092] Step S910: Acquire a detection signal of a detection component disposed on a rear armrest of the electric vehicle.

[0093] Among them, step S910 is the same as the above reference Figure 8 The described step S810 corresponds.

[0094] Step S920: determine whether the pressure value represented by the pressure signal is greater than a preset pressure threshold.

[0095] The preset pressure threshold is a specific value that can be determined by testing or simulation according to actual conditions. When the pressure applied to the pressure sensor is greater than the preset pressure threshold, it indicates that the number of passengers on the seat 112 is two or more than two. For example, after testing or simulation, when two people sit on the seat 112 in a conventional manner, the minimum pressure applied to the pressure sensor is 2 MPa, and the preset pressure threshold can be selected as 2 MPa. In step S920, the pressure value represented by the pressure signal is compared with the preset pressure threshold. When the pressure value represented by the pressure signal is greater than the preset pressure threshold, it indicates that there may be two or more people riding the same electric vehicle 100, and the following step S930 can be executed.

[0096] Step S930: determine whether the change in the pressure value represented by the pressure signal meets the preset fluctuation condition.

[0097] Due to factors such as the rider's relatively strong physique or items such as clothing and backpacks touching the rear armrest 120, the pressure value represented by the pressure signal may be greater than the preset pressure threshold in a single-riding scenario. In order to reduce the probability of misjudgment, the determination of the passenger status of the electric vehicle 100 may also consider the change in the pressure value represented by the pressure signal. Specifically, during the process of the second rider sitting on the seat cushion 112, the pressure value represented by the pressure signal will usually increase from zero or a smaller value to a larger value (for example, a value greater than the aforementioned pressure threshold) within a certain time range, and then tend to stabilize (that is, the amplitude of the fluctuation is within a smaller range). If the pressure sensor is triggered by a backpack or clothing of a single rider, even if the pressure value represented by the pressure signal at a certain time point is greater than the pressure threshold, the pressure value represented by the pressure signal may continue to fluctuate for a period of time, or drop to a smaller value (for example, to zero) at a certain time point due to factors such as the rider's posture adjustment; and due to the length limitation of the seat cushion 112, when more than two riders sit on the seat cushion 112, even if the riders adjust their postures, the pressure value represented by the pressure signal will usually not drop to zero or a smaller value close to zero. Therefore, the change of the pressure value represented by the pressure signal can be analyzed to determine whether it meets the preset fluctuation condition, so as to more accurately determine the passenger state of the electric vehicle 100. The specific items of the preset fluctuation condition can be selected as needed, for example, including conditions about the duration of the pressure value being greater than the preset pressure threshold, the maximum drop after the pressure value is greater than the preset pressure threshold, the frequency of pressure value fluctuations, etc. In a possible implementation, the preset fluctuation condition includes the duration of the pressure value being greater than the preset pressure threshold being greater than the preset duration.

[0098] Step S940: When it is determined that the pressure value represented by the pressure signal is greater than the preset pressure threshold and the change condition meets the preset fluctuation condition, it is determined that the passenger state of the electric vehicle is a multi-person riding state.

[0099] When the judgment results of step S930 and step S940 are both "yes", it can be considered that there is a high possibility that two or more people are riding in the electric vehicle 100, so the passenger state of the electric vehicle 100 can be a multi-person riding state.

[0100] Step S950: When it is determined that the passenger state of the electric vehicle is a multi-person riding state, a preset multi-person riding prevention operation is executed.

[0101] Among them, step S950 is the same as the above reference Figure 8 The described step S830 corresponds.
