[0031] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0032] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0033] According to one aspect of an embodiment of the present application, a scooter is provided. Optionally, in this embodiment, Figure 1 As shown, the above-mentioned scooter may include: a motor 102, a tire pressure detection module 104, a data transmission component 106 and a central control module 108, wherein the tire pressure detection module 104 is arranged on the wheel hub of the designated tire of the scooter, and can be used to detect the tire pressure data of the designated tire of the scooter; the data transmission component 106 is connected to the tire pressure detection module 104 and the central control module 108, and is used to transmit the tire pressure data of the designated tire to the central control module 108, and the data transmission component 106 and the tire pressure detection module 104 can be connected in a wired manner or in a wireless manner. The data transmission component 106 can be connected to the central control module 108 in a wired or wireless manner; the central control module 108 is also connected to the motor 102, and is used to adjust the output power of the motor 102 based on the actual tire pressure of the specified tire when it is detected that the tire pressure data of the specified tire is valid and the actual tire pressure of the specified tire represented by the tire pressure data of the specified tire is less than the specified tire pressure threshold. The connection between the central control module 108 and the motor 102 can be in a wired or wireless manner.

[0034] The scooter in this embodiment can be applied to the field of scooters. Scooters have become an optional means of travel due to their ease of control, and their safety and stability need to be ensured. Tire pressure is one of the key factors affecting the performance and riding safety of scooters. Normal tire pressure can not only improve the maneuverability of scooters, but also effectively extend the service life of tires and ensure riding safety. Too low tire pressure will increase the resistance of the scooter when it is running, which not only affects the speed, but also may accelerate tire wear and increase the risk of tire blowout. Especially on uneven roads, tires with low tire pressure are more susceptible to impact, causing safety hazards. On the contrary, although too high tire pressure can reduce rolling resistance, it will reduce the contact area between the tire and the ground, affect the grip, and reduce the stability of the scooter when turning or emergency braking. In addition, too high tire pressure will also increase the risk of tire blowout. Therefore, testing the tire pressure of scooters and ensuring that their tire pressure remains within the normal range is an effective measure to ensure riding safety and improve riding experience.

[0035] The scooters of the related art do not have a tire pressure detection function. Whether the tire pressure of the scooter is normal is usually determined by the rider through manual pressing or visual observation. The above tire pressure detection method is affected by the accuracy of manual judgment, and it is also easy to forget the detection. To this end, a pressure sensor can be installed on the inside of the tire to directly collect the tire pressure of the tire, so as to obtain the real-time tire pressure of the tire in real time. And promptly remind the rider when abnormal tire pressure is detected. However, the above tire pressure detection method requires the rider to perform subsequent processing based on the received reminder information, and the actual road conditions are complicated, and there may be problems with untimely information acquisition; in addition, the acquisition of reminder information and the processing of abnormal tire pressure will distract the rider's attention and increase the safety risk of the riding process. In addition, the pressure sensor relies on the built-in battery for power supply. Due to the battery life limit, it is necessary to regularly maintain and replace the battery, and the maintenance cost is high.

[0036] In addition, if an indirect tire pressure detection method is used, the indirect tire pressure detection method usually determines the tire pressure by detecting the wheel speed of the tire, and then determines whether the tire pressure exceeds the set tire pressure range. This method does not rely on the built-in battery for power and can be used for a long time, but the false alarm rate is high, there are safety hazards, and the safety is poor.

[0037] In order to at least partially solve the above technical problems, in the present embodiment, the tire pressure data of the designated tire of the scooter is detected by a tire pressure detection module, and the tire pressure detection module is arranged on the wheel hub of the designated tire of the scooter, and adopts a direct tire pressure detection method to directly collect the internal air pressure of the tire, so as to obtain an accurate tire pressure value, and transmit the tire pressure data to the central control module through a data transmission component, and the central control module analyzes the received tire pressure data, so as to obtain the actual tire pressure of the designated tire in real time, and directly adjusts the output power of the motor when the tire pressure of the designated tire is detected to be abnormal, so as to ensure the safety of the scooter driving process without the participation of the rider.

[0038] In this embodiment, the tire pressure detection module can detect the tire pressure data of the designated tire of the scooter by direct tire pressure detection. The tire pressure detection module can be set on the wheel hub of the designated tire of the scooter at a position where the tire pressure of the designated tire can be measured. For example, the tire pressure detection module can be set on the inner side of the wheel hub of the designated tire, such as Figure 2 Here, the designated tire may be any tire on the scooter, and a tire pressure detection module may be provided on the wheel hub of each tire of the scooter to achieve comprehensive tire pressure detection of the scooter tire.

[0039] For the tire pressure data of the specified tire detected by the tire pressure detection module, the tire pressure data of the specified tire can be transmitted to the central control module of the scooter through the data transmission component. Here, the data transmission component can transmit data by wire or wirelessly, and the wireless method can use a wireless carrier. A wireless carrier refers to a high-frequency electromagnetic wave used to carry and transmit information signals in wireless communication. A wireless carrier can be used as a carrier to realize wireless data transmission, wireless charging, etc.

[0040] The central control module may be a central control screen of a scooter or a similar component, which may parse the tire pressure data of a specified tire. Parsing the tire pressure data of a specified tire may include: performing a determination operation, the determination operation being an operation of determining whether the actual tire pressure of a specified tire represented by the tire pressure data of the specified tire is normal, or performing a verification operation and the above-mentioned determination operation, the verification operation being an operation of verifying whether the tire pressure data of the specified tire is valid. The above-mentioned verification operation may be pre-set, for example, data check code verification, data format verification, repeated transmission and multi-band confirmation, etc. The above-mentioned determination operation may determine whether the actual tire pressure of a specified tire is within a set tire pressure range (for example, greater than or equal to a specified tire pressure threshold). In this embodiment, the manner of parsing the tire pressure data of a specified tire is not limited.

[0041] Based on the analysis result of the tire pressure data of the specified tire, the central control module can perform corresponding processing operations. For the scenario where only the judgment operation is performed, when the actual tire pressure of the specified tire is normal (the actual tire pressure of the specified tire is within the set tire pressure range), you can wait to continue to receive new tire pressure data of the specified tire, and the historical tire pressure data of the specified tire can be discarded or saved. When the actual tire pressure of the specified tire is abnormal, the tire pressure abnormality processing operation is performed, and the tire pressure abnormality processing operation may include at least one of the following: tire pressure abnormality reminder, motor output power adjustment. The tire pressure abnormality reminder can be: control to send a prompt message for prompting that the tire pressure of the specified tire is insufficient, and the motor output power adjustment can be: based on the actual tire pressure of the specified tire, the motor output power is adjusted (it can be to reduce the motor power), and the motor output power is positively correlated with the actual tire pressure of the specified tire. The lower the actual tire pressure of the specified tire, the lower the motor output power of the adjusted scooter.

[0042] For the scenario where the verification operation and the determination operation are performed simultaneously (the determination operation may be performed after the verification operation results in the tire pressure data of the specified tire being valid), when the tire pressure data of the specified tire is valid and the actual tire pressure of the specified tire is normal, or when the tire pressure data of the specified tire is valid and the actual tire pressure of the specified tire is abnormal (the actual tire pressure of the specified tire is outside the set tire pressure range), the same or similar operation as described above is performed. When the tire pressure data of the specified tire is invalid, the tire pressure data of the specified tire may be ignored, or the number of invalid tire pressure data received for the specified tire may be recorded, and when the number of invalid tire pressure data received for the specified tire reaches a set number threshold, a detection abnormality reminder is performed, and the detection abnormality reminder may be: controlling the issuance of a prompt message indicating that a failure has occurred in the tire pressure detection of the specified tire.

[0043] The above-mentioned tire pressure detection module can be powered by a battery, but the battery-powered mode has problems such as short service life. To this end, in this embodiment, the following wireless carrier power supply scheme can be adopted: a tire pressure detection module, which is used to detect the tire pressure data of the designated tire of the scooter, wherein the tire pressure detection module can be powered by a wireless carrier; a data transmission component, which is used to transmit the tire pressure data of the designated tire to the central control module; the central control module is used to parse the tire pressure data of the designated tire. The way in which the central control module parses the tire pressure data of the designated tire and the way in which the corresponding processing operation is performed based on the parsed result of the tire pressure data of the designated tire are similar to the above, and will not be repeated here.

[0044] Through the embodiments provided by the present application, the scooter includes: a motor; a tire pressure detection module arranged on the wheel hub of a designated tire of the scooter; a data transmission component; and a central control module; wherein the tire pressure detection module is used to detect the tire pressure data of the designated tire of the scooter; the data transmission component is used to transmit the tire pressure data of the designated tire to the central control module; the central control module is used to adjust the output power of the motor based on the actual tire pressure of the designated tire when it is detected that the tire pressure data of the designated tire is valid and the actual tire pressure of the designated tire represented by the tire pressure data of the designated tire is less than the specified tire pressure threshold, wherein the output power of the motor is positively correlated with the actual tire pressure of the designated tire, thereby solving the technical problem of low safety of the scooter in the related art and improving the safety of the scooter.

[0045] In an exemplary embodiment, Figure 3 As shown, the data transmission component includes a first processing component, a wireless transmitting board, a first antenna, a second antenna and a wireless receiving board, the wireless transmitting board is connected to the first antenna, and the second antenna, the wireless receiving board and the central control module are connected in sequence; the first processing component is used to transmit the tire pressure data of the specified tire to the wireless transmitting board; the wireless transmitting board is used to transmit the tire pressure data of the specified tire to the second antenna via the first antenna through a wireless carrier; the wireless receiving board is used to transmit the tire pressure data of the specified tire received through the second antenna to the central control module.

[0046] In this embodiment, the tire pressure data of the designated tire can be transmitted to the central control module via a wireless carrier, and the above process can be controlled and executed by the first processing component. The first processing component can be a control component such as an MCU (Microcontroller Unit), which can be used to transmit the tire pressure data of the designated tire to the wireless transmitter board, wherein the MCU is a single-chip computer integrating a CPU (Central Processing Unit), a memory and a peripheral interface, and can be programmed to implement logic control and data processing.

[0047] The wireless transmitter board can transmit the tire pressure data of the specified tire to the second antenna via the first antenna through a wireless carrier; and the tire pressure data of the specified tire received by the second antenna can be transmitted to the central control module via the wireless receiver board. Here, the wireless transmitter board can load the baseband signal (i.e., tire pressure data) onto the high-frequency carrier through a modulator, and amplify the modulated signal to increase the transmission distance and signal strength; the first antenna (i.e., the transmitting antenna) can efficiently radiate the high-frequency electrical signal modulated by the wireless transmitter board into electromagnetic waves; the second antenna (i.e., the receiving antenna) can capture electromagnetic waves in space (including electromagnetic waves radiated by the first antenna); the wireless receiver board can demodulate the electromagnetic wave signal captured by the second antenna and restore it to a processable electrical signal.

[0048] In this embodiment, the tire pressure data of the specified tire can be transmitted to the wireless transmitting board by wired transmission. The wireless transmitting board can modulate the tire pressure data of the specified tire, and the modulated tire pressure data is radiated as an electromagnetic wave signal by the first antenna, and transmitted to the second antenna by wireless carrier. It should be noted that in order to ensure that the tire pressure data can be smoothly transmitted from the first antenna to the second antenna, in this embodiment, the distance between the first antenna and the second antenna can be less than 20 meters. Optionally, the frequency band of the wireless carrier here can be 433MHz. After the second antenna receives the electromagnetic wave signal of the tire pressure data from the first antenna, the wireless receiving board can demodulate the electromagnetic wave signal captured by the second antenna, convert it into an electrical signal, and transmit it to the central control module by wired transmission.

[0049] Through this embodiment, a wireless carrier is used to transmit tire pressure data, and the tire pressure data is transmitted to the central control module via the wireless transmitting board, the first antenna, the second antenna and the wireless receiving board. This can reduce the restrictions of the wired transmission method on the scooter structure and ensure that the tire pressure data is stably transmitted to the central control module.

[0050] In an exemplary embodiment, Figure 4 As shown, the scooter also includes a first carrier board, a third antenna, a fourth antenna, a second carrier board, a motor Hall board of the motor and a motor control board of the motor, wherein the first carrier board is connected to the third antenna, and the fourth antenna, the second carrier board, the motor Hall board and the motor control board are connected to the central control module in sequence.

[0051] The first carrier board can load the baseband signal (i.e., tire pressure data) onto the carrier through modulation technology to form a high-frequency modulated signal, and amplify the modulated signal to increase the transmission distance and signal strength; the third antenna can efficiently radiate the high-frequency electrical signal modulated by the first carrier board into electromagnetic waves; the fourth antenna can capture electromagnetic waves in space (including electromagnetic waves radiated by the third antenna); the second carrier board can demodulate the electromagnetic wave signal captured by the fourth antenna in a demodulation method corresponding to the modulation method of the first carrier board, and restore it to a processable electrical signal. Here, the modulation method may include but is not limited to: amplitude modulation, frequency modulation, and phase modulation.

[0052] The Hall plate is an electronic component based on the Hall effect and can be used to detect current and magnetic field or monitor position and motion state. In this embodiment, the motor Hall plate can monitor the operating state of the motor, for example, monitor the current size, and trigger a protection mechanism when overcurrent or short circuit occurs to prevent motor damage; the motor control board can control the operating state of the motor, for example, control the output power of the motor.

[0053] Correspondingly, in order to transmit the tire pressure data of the designated tire to the central control module, the first processing component can also transmit the tire pressure data of the designated tire to the first carrier board, and the first carrier board transmits the tire pressure data of the designated tire to the fourth antenna via the third antenna through a wireless carrier; the tire pressure data of the designated tire received by the fourth antenna is transmitted to the central control module via the second carrier board, the motor Hall board and the motor control board.

[0054] In this embodiment, the tire pressure data is transmitted to the first carrier board by wired transmission, the wireless transmitter board can modulate the tire pressure data, and the modulated tire pressure data is radiated as an electromagnetic wave signal by the third antenna, and transmitted to the fourth antenna by wireless carrier. It should be noted that in order to ensure that the tire pressure data can be smoothly transmitted from the third antenna to the fourth antenna, the distance between the first antenna and the second antenna can be less than 20 cm. In addition, in order to prevent frequency band interference, the frequency band of the wireless carrier in this embodiment is different from the frequency band of the wireless carrier in the aforementioned embodiment. For example, the frequency band of the wireless carrier here can be 100KHz.

[0055] After the fourth antenna receives the electromagnetic wave signal of the tire pressure data from the third antenna, the second carrier board can demodulate the electromagnetic wave signal captured by the fourth antenna, convert it into an electrical signal, and transmit it to the motor Hall board, the motor control board in sequence through wired transmission, and finally to the central control module.

[0056] Optionally, the tire pressure detection board can be powered and data transmitted through a wireless power carrier (realized by the first carrier board and the second carrier board), and there are two data transmission channels (realized by the third antenna and the fourth antenna) to increase the robustness of data transmission. Figure 5 As shown, the tire pressure data of the tire pressure detection module can be transmitted to the central control module through two different data transmission channels, and the two data transmission channels can improve the reliability and robustness of data transmission. The frequency band of the wireless carrier between the first antenna and the second antenna and the frequency band of the wireless carrier between the third antenna and the fourth antenna are kept different to prevent frequency band interference. For example, the frequency band of the wireless carrier between the first antenna and the second antenna can be 433MHz, and the frequency band of the wireless carrier between the third antenna and the fourth antenna can be 100KHz.

[0057] It should be noted that the tire pressure data of the designated tire can also be transmitted to the central control module only via the data transmission channels of the first carrier board, the third antenna, the fourth antenna, the second carrier board, the motor Hall board and the motor control board, and the central control module parses the tire pressure data of the designated tire. The tire pressure detection module can be powered by a wireless carrier, and the power supply through the wireless carrier can be achieved by the wireless carrier from the fourth antenna to the third antenna. The first processing component can be a processing component in the first carrier board (for example, MCU), or it can be an independently set control component. The control of the first processing component to transmit the tire pressure data of the designated tire to the wireless transmitting board can also be directly executed by the control logic built into the tire pressure detection module, that is, the tire pressure detection module is used to detect the tire pressure data of the designated tire of the scooter, and transmit the tire pressure data of the designated tire to the wireless transmitting board without the control of the first processing component.

[0058] Through this embodiment, by setting up another data transmission channel including a first carrier board, a third antenna, a fourth antenna, a second carrier board, a motor Hall plate and a motor control board, tire pressure data can still be transmitted when one of the data transmission channels fails, thereby improving the robustness of data transmission.

[0059] In an exemplary embodiment, the central control module is also used to verify the validity of the tire pressure data of at least one designated tire when the tire pressure data of at least one designated tire is received; when there is valid tire pressure data in the tire pressure data of at least one designated tire, determine whether the actual tire pressure of the designated tire represented by the valid tire pressure data of the designated tire is less than the designated tire pressure threshold.

[0060] In order to ensure the reliability of the tire pressure data received by the central control module, after the central control module receives the tire pressure data, a verification operation similar to the above can be performed on the tire pressure data of the specified tire. Here, the verification operation performed can be set based on experience, such as data check code verification, data format check, CRC (Cyclic Redundancy Check) check code detection, etc., which is not limited in this embodiment.

[0061] For tire pressure data that has been verified to be invalid, the central control module can directly discard or ignore the invalid data; for data that has been verified to be valid, the central control module can continue to perform a similar judgment operation as described above on the tire pressure data of the specified tire. The execution process of the judgment operation can be: determine the actual tire pressure of the specified tire represented by the tire pressure data of the specified tire, and determine whether the actual tire pressure of the specified tire is less than the specified tire pressure threshold. Here, the specified tire pressure threshold is a pre-set, minimum normal tire pressure value. When the actual tire pressure of the specified tire is less than the specified tire pressure threshold, it can be considered that the tire pressure of the specified tire is too low. At this time, the rider can be reminded, and the output power of the motor can also be controlled to be reduced. For example, the central control module can transmit instructions to the motor control board so that the motor control board controls the reduction of the output power of the motor to ensure the safety of the scooter.

[0062] Through this embodiment, the central control module verifies the validity of the received tire pressure data, which can improve the reliability of the tire pressure data; and first performing a verification operation on the tire pressure data and then performing a determination operation on the tire pressure data can improve the efficiency of the operation execution and improve the utilization rate of computing resources.

[0063] In an exemplary embodiment, in order to ensure the power supply of the scooter, as Figure 6 As shown, the scooter also includes a power supply, which is connected to the motor control board. The power supply can provide stable electric energy for driving the motor and other devices on the scooter.

[0065] In this embodiment, the power supply can also provide wireless power supply for the tire pressure detection module. The second processing component and the first processing component can be the same type of control component, or different types of control components, which can control the conversion of the power supply's electric energy into a wireless power supply carrier, and the converted wireless power supply carrier can be sent to the third antenna of the first carrier board via the fourth antenna of the second carrier board, and the conversion of the power supply's electric energy into a wireless power supply carrier can be performed by the second carrier board. The second carrier board can modulate the electric energy into a wireless power supply carrier of a specific frequency and send the wireless power supply carrier through the fourth antenna. After the third antenna receives the above-mentioned wireless power supply carrier, the first carrier board can convert the electromagnetic energy in the wireless power supply carrier into a DC voltage through a rectifier and a voltage stabilizer, and use the DC voltage to power the tire pressure detection module. Here, the rectifier is responsible for converting the electromagnetic energy in the wireless power supply carrier into DC power, and the voltage stabilizer further stabilizes the converted DC power at a voltage level suitable for powering the tire pressure detection module, ensuring that the tire pressure detection module can continue to work stably.

[0066] Optionally, the structures of the first carrier plate and the second carrier plate are as follows: Figure 7 As shown. Among them, the second carrier board includes: DCDC (DC-to-DC Converter), which can realize DC voltage step-up and step-down conversion through a switching circuit to achieve output voltage stability; MCU; LDO (Low Dropout Regulator), that is, a voltage regulator, which can achieve low-noise voltage regulation through linear adjustment to ensure output voltage stability; a wireless module, connected to the fourth antenna, used to drive the fourth antenna to send a wireless power supply carrier. The second carrier board can convert the power supply of the power supply into a wireless power supply carrier and send it to the first carrier board, and the first carrier board converts the wireless power supply carrier into a stable DC voltage to power the tire pressure detection module. The first carrier board includes: a strain gauge, which can change resistance according to the deformation of an object, and can be used to assist in detecting tire pressure; strain acquisition (i.e., a strain acquisition circuit) can be used to process the weak electrical signal output by the strain gauge, amplify the electrical signal and convert it into a digital signal to facilitate subsequent data transmission and processing; MCU; a rectifier bridge, which can be used to convert AC power into DC power, and can convert AC electromagnetic energy in the wireless power carrier received by the third antenna into DC power, so as to facilitate power supply to the tire pressure detection module; an antenna module, which is connected to the third antenna and can be used to drive the third antenna to receive the wireless power carrier.

[0067] It should be noted that the second processing component can be a processing component in the second carrier board (for example, MCU) or an independently arranged processing component. In addition to the above-mentioned control circuit, other control circuits can also be used as long as the tire pressure detection module can be powered by a wireless power supply carrier.

[0068] Through this embodiment, the electric energy of the power source is transmitted via a wireless power carrier to power the tire pressure detection module, which can solve the problem of short battery life of battery-powered power in related technologies and reduce the maintenance cost of replacing batteries.

[0069] In an exemplary embodiment, in order to ensure the normal operation of the tire pressure detection module when the wireless power supply is abnormal, the scooter also includes a backup battery for the tire pressure detection module; the first processing component is also used to start the backup battery when the startup condition of the backup battery is met, so as to power the tire pressure detection module through the backup battery, wherein the startup condition includes at least one of the following: the wireless power supply of the tire pressure detection module is abnormal, and a startup instruction of the backup battery is received.

[0070] The structure related to the tire pressure detection module in the scooter can be as follows Figure 8 As shown, the tire pressure data detected by the pressure sensor (an example of a tire pressure detection module) can be converted into a digital signal by an ACD (Analog to Digital Converter) and then transmitted to an MCU (an example of a first processing component). The tire pressure data processed by the MCU is input into a wireless transmitter chip (an example of a wireless transmitter board) as a DIN (Digital Input). When the backup battery is started, the backup battery supplies power to the MCU and the pressure sensor.

[0071] Through this embodiment, by providing a backup battery for the tire pressure detection module, the normal operation of the tire pressure detection module can be ensured when a wireless power supply failure occurs, thereby improving the stability of the tire pressure detection system.

[0072] In an exemplary embodiment, the central control module is further used to determine the tire pressure interval to which the actual tire pressure of a specified tire in a group of tire pressure intervals belongs, and obtain a target tire pressure interval, wherein the tire pressure intervals in a group of tire pressure intervals are adjacent in sequence, and a tire pressure interval in a group of tire pressure intervals corresponds to a proportional factor, and the larger the tire pressure interval in a group of tire pressure intervals, the larger the corresponding proportional factor; the product of the proportional factor corresponding to the target tire pressure interval and the rated output power of the motor is used as the adjusted output power, and the output power of the motor of the scooter is adjusted.

[0073] In this embodiment, in order to adjust the output power of the motor based on the actual tire pressure of a specified tire, the output power of the motor may be adjusted in a step-by-step manner. The step-by-step adjustment may be performed based on a set of tire pressure intervals. The tire pressure intervals in a set of tire pressure intervals are adjacent in sequence. Each tire pressure interval may correspond to a proportional factor, and the larger the tire pressure interval, the larger the corresponding proportional factor. For example, Fig. 9 As shown, tire pressure intervals 1 to 5 increase sequentially, and their corresponding proportional factors also increase sequentially.

[0074] After determining the actual tire pressure of the specified tire, the central control module can determine the tire pressure interval to which the actual tire pressure of the specified tire belongs in a set of tire pressure intervals, obtain the target tire pressure interval, and then multiply the proportional factor corresponding to the target tire pressure interval by the rated output power of the motor as the adjusted output power, thereby adjusting the output power of the motor. Here, the rated output power of the motor is the set default output power, and its value can be a default value.

[0075] Through this embodiment, a step-by-step output power adjustment method is adopted to adjust the output power of the motor according to the proportional factor corresponding to the tire pressure range corresponding to the actual tire pressure. This can improve the convenience of output power adjustment and improve the safety of driving when the tire pressure is too low.

[0076] In an exemplary embodiment, the tire pressure threshold and the number of tire pressure intervals in a set of tire pressure intervals, the range of each tire pressure interval, and the proportional factor corresponding to each tire pressure interval can be configured as needed. In this embodiment, as shown in Table 1, the tire pressure threshold can be 40PSI (Pounds per Square Inch), and a set of tire pressure intervals includes a first tire pressure interval, a second tire pressure interval, a third tire pressure interval, and a fourth tire pressure interval, wherein the first tire pressure interval is [30PSI, 40PSI), and the proportional factor corresponding to the first tire pressure interval is 80%, the second tire pressure interval is [20PSI, 30PSI), and the proportional factor corresponding to the second tire pressure interval is 60%, the third tire pressure interval is [10PSI, 20PSI), and the proportional factor corresponding to the third tire pressure interval is 20%, and the fourth tire pressure interval is [0, 10PSI), and the proportional factor corresponding to the fourth tire pressure interval is 0%.

[0077] Table 1

[0078]

[0079] Here, the designated tire pressure threshold of 40PSI is the lowest normal tire pressure. When the actual tire pressure is not less than the designated tire pressure threshold, the tire pressure is considered normal. When the actual tire pressure is less than the designated tire pressure threshold, the tire pressure is considered too low. The output power of the motor can be reduced accordingly, and the motor output can be stopped when the actual tire pressure is less than 10PSI.

[0080] In addition, the proportional factors corresponding to each tire pressure range can ensure that the riding power is in the maximum efficiency range. Controlling the output power with the proportional factors corresponding to the tire pressure range can reduce tire wear and ensure driving safety.

[0081] Through this embodiment, by using the configured tire pressure intervals and specific values ​​of the proportional factors, the output power of the motor can be accurately controlled after obtaining the actual tire pressure, thereby ensuring safety during driving, reducing tire wear and increasing tire service life.

[0082] In an exemplary embodiment, the central control module is also used to control the issuance of a first prompt message when it is detected that the tire pressure data of the specified tire is valid and the actual tire pressure of the specified tire represented by the tire pressure data of the specified tire is less than a specified tire pressure threshold, wherein the first prompt message is used to prompt that the tire pressure of the specified tire is insufficient.

[0083] For the central control module, when it is detected that the tire pressure data of the specified tire is valid and the actual tire pressure of the specified tire represented by the tire pressure data of the specified tire is less than the specified tire pressure threshold, the first prompt information of insufficient tire pressure can be issued by controlling the prompt component to remind the rider of the insufficient tire pressure in real time. Here, the form of the first prompt information can be set as needed, for example, the prompt information of insufficient tire pressure is output by voice through a sound-emitting device (the prompt component includes a sound-emitting device), or the prompt information of insufficient tire pressure is output by display screen (the prompt component includes a display screen), which is not limited in the present embodiment.

[0084] Through this embodiment, when the tire pressure data is valid and the actual tire pressure is insufficient, a prompt message of insufficient tire pressure is output, which can remind the rider of the insufficient tire pressure so that the rider can replenish the tire pressure, pull over, etc. in time to ensure the safety of the riding process.

[0085] In an exemplary embodiment, the central control module is also used to update the recorded number of detection failures when it is detected that the tire pressure data of the specified tire is invalid, wherein the number of detection failures is the number of times the tire pressure detection of the specified tire has failed; when the updated number of detection failures is greater than a specified number threshold, control the issuance of a second prompt message, wherein the second prompt message is used to indicate that a failure has occurred in the tire pressure detection of the specified tire.

[0086] The invalid tire pressure data of the specified tire may be caused by unexpected reasons, such as abnormal signals, or by abnormal tire pressure detection modules. If the tire pressure data of the specified tire is detected to be invalid and a prompt message is directly controlled, there is a possibility of a false alarm. For this reason, in this embodiment, a threshold of the number of detection failures can be set, and an abnormal prompt is issued only when the number of detection failures reaches the set threshold.

[0087] For the central control module, when it is detected that the tire pressure data of the specified tire is invalid, the recorded number of detection failures can be updated, that is, the number of times the tire pressure detection of the specified tire has failed; when the updated number of detection failures is greater than the specified number threshold, the control sends a second prompt message indicating that a failure has occurred in the tire pressure detection of the specified tire.

[0088] Here, the specified number of times threshold can be set based on experience, for example, 10 times, 12 times or 15 times, etc. The prompt method of the second prompt information is similar to the form of the first prompt information in the aforementioned embodiment. In this embodiment, there is no limitation on the specified number of times threshold and the content and issuance method of the second prompt information.

[0089] Through this embodiment, when the number of tire pressure detection failures reaches a set number threshold, a prompt message of tire pressure detection failure is output, which can remind the rider of abnormal tire pressure detection so that the rider can pay attention to the tire pressure in time. At the same time, it can also remind the rider to pay attention to the operation of the scooter to ensure the safety of the riding process.
