[0002] E-bikes have developed rapidly in recent years, combining the experience of traditional cycling with electric assistance.

[0040] Figure 1 This is a flowchart of a sleep control method for an electric-assisted bicycle provided in an embodiment of the present invention. This embodiment is applicable to different levels of sleep control when the electric-assisted bicycle is stopped. This method can be executed by the sleep control device of the electric-assisted bicycle, such as... Figure 1 As shown, the hibernation control method specifically includes the following steps:

[0041] S110: When the vehicle is parked in riding mode for a first preset time, or when the electric-assisted bicycle is in riding mode, control the electric-assisted bicycle to enter the first sleep mode according to external commands.

[0042] In this embodiment, the first sleep mode is the sentinel mode; the power consumption of the electric-assisted bicycle in the first sleep mode is the first preset current power consumption.

[0043] When the vehicle is parked in riding mode for a first preset time (e.g., 3 minutes), the electric-assisted bicycle is automatically controlled to enter the first sleep mode; or when the electric-assisted bicycle is in riding mode, it is actively controlled to enter the first sleep mode according to an external command (which can be a command sent by the APP); that is, this embodiment can enter the first sleep mode automatically or actively.

[0044] The control of an electric-assisted bicycle to enter the first sleep mode can be achieved by controlling different components within the electric-assisted bicycle to be under different first current power consumption levels, thereby entering the first sleep mode; the sum of the different first current power consumption levels is the first preset current power consumption.

[0045] S120. When the first sleep mode runs for a second preset time, or when the current battery level of the electric-assisted bicycle is less than the first preset battery level, or when the electric-assisted bicycle is in the first sleep mode, control the electric-assisted bicycle to enter the second sleep mode according to the external command.

[0046] In this embodiment, the second sleep mode is a keep-alive mode; the power consumption of the electric-assisted bicycle in the second sleep mode is the second preset current power consumption; the second preset current power consumption is less than the first preset current power consumption.

[0047] When the first sleep mode runs for a second preset time (e.g., 3 days), or when the current battery level of the electric-assisted bicycle is less than the first preset battery level (e.g., 30%), the electric-assisted bicycle is automatically controlled to enter the second sleep mode; or when the electric-assisted bicycle is in the first sleep mode, it is actively controlled to enter the second sleep mode according to an external command (which can be a command sent by the APP). That is, this embodiment can automatically or actively enter the second sleep mode in different ways.

[0048] The second sleep mode can be controlled by placing different components within the electric-assist bicycle at different second current power consumption levels, thereby entering the second sleep mode; the sum of the different second current power consumptions is the second preset current power consumption.

[0049] S130. When the second sleep mode runs for a third preset time, or when the current battery level of the electric-assisted bicycle is less than the second preset battery level, or when the electric-assisted bicycle is in the second sleep mode, control the electric-assisted bicycle to enter the third sleep mode according to the external command.

[0050] In this embodiment, the third sleep mode is the factory mode; the power consumption of the electric-assisted bicycle in the third sleep mode is the third preset current power consumption; the third preset current power consumption is less than the second preset current power consumption.

[0051] When the second sleep mode runs for a third preset time (e.g., 30 days), or when the current battery level of the electric-assisted bicycle is less than the second preset battery level, the electric-assisted bicycle will automatically enter the third sleep mode; the second preset battery level is less than the first preset battery level; the second preset battery level is, for example, 0%. When the electric-assisted bicycle is in the second sleep mode, it will actively enter the third sleep mode according to external instructions; that is, this embodiment can automatically or actively enter the third sleep mode in different ways.

[0052] In this embodiment of the invention, a multi-level sleep mode that gradually reduces power consumption avoids the problem of battery cell damage caused by prolonged storage of batteries in electric bicycles due to high power consumption caused by a single-level sleep mode. This achieves protection of the battery cells.

[0053] Optionally, based on the above embodiments, further detailed explanations can be provided on how to enter different hibernation modes; Figure 2 This is a flowchart of another sleep control method for an electric-assisted bicycle provided in an embodiment of the present invention; as shown below. Figure 2 As shown, the hibernation control method includes the following steps:

[0054] S210. When the vehicle is parked in riding mode for a first preset time, or when the electric-assisted bicycle is in riding mode, the light strip module and motor controller module inside the electric-assisted bicycle are turned off according to external commands, the instrument module and Bluetooth module inside the electric-assisted bicycle are put into low power mode, and the BMS module and 4G module inside the electric-assisted bicycle are put into shallow sleep state so that the electric-assisted bicycle enters the first sleep mode.

[0055] in, Figure 3 This is a schematic diagram of the system structure of an electric-assisted bicycle in the prior art; such as Figure 3 As shown, an electric-assist bicycle includes at least a lighting control module 10, an instrument module 20, a Bluetooth module 30, a BMS module 40, a 4G module 50, and a motor controller module 60. Generally, in the riding mode of the electric-assist bicycle, the lighting control module 10, the instrument module 20, the Bluetooth module 30, the BMS module 40, the 4G module 50, and the motor controller module 60 continuously send light strip information, vehicle status information, Bluetooth information, battery information, positioning information, and motor information to the CAN bus.

[0056] In this embodiment, when the light strip module 10 and motor controller module 60 in the electric-assisted bicycle are turned off, and the instrument module 20 and Bluetooth module 30 are put into low-power mode (e.g., the display in the instrument module is turned off, the instrument module does not send data to the CAN bus, and the main chip in the instrument module does not perform overall data calculation), the overall power consumption of the electric-assisted bicycle is reduced to the first current power consumption value.

[0057] When the BMS module 40 inside the electric-assist bicycle enters a shallow sleep state, the overall power consumption of the electric-assist bicycle is reduced to another first current power consumption value (e.g., 0.5mA); when the 4G module 50 inside the electric-assist bicycle enters a shallow sleep state, the overall power consumption of the electric-assist bicycle is reduced to another first current power consumption value (e.g., 2.5mA); these three first current power consumption values ​​are equal to the first preset current loss.

[0058] Specifically, controlling the BMS module 40 to enter a shallow sleep state includes: controlling the CAN transceiver in the BMS module to turn on and off periodically so that the BMS module sends normal data (which can be battery information) to the CAN bus at a preset frequency (e.g., every hour; this preset frequency is less than the normal frequency); and controlling the BMS module 40 to send a fault signal to the CAN bus and send the fault signal on the CAN bus to the cloud platform when the battery fails; and also controlling the BMS module 40 to monitor the data on the CAN bus in real time to trigger wake-up (e.g., the BMS module 40 can monitor the data on the CAN bus based on the detected voltage signal on the CAN bus to trigger wake-up).

[0059] Controlling the 4G module 50 to enter a shallow sleep state includes: controlling the CAN transceiver inside the 4G module 50 to turn on and off periodically so that the 4G module 50 sends normal data (normal data may include location information and heartbeat data) to the CAN bus at a preset frequency (e.g., per hour; the preset frequency is less than the normal frequency) and sends the fault signal on the CAN bus to the cloud platform; and also controlling the 4G module 50 to monitor the data on the CAN bus in real time to trigger wake-up.

[0060] It should also be noted that when the electric-assist bicycle is in the first sleep mode, it can also actively switch to the normal riding mode according to the first external button command, or Bluetooth external command, or 4G external command, thus realizing the mutual switching between different sleep modes and improving the flexibility of control.

[0061] S220. When the first sleep mode runs for a second preset time, or when the current battery level of the electric-assisted bicycle is less than the first preset battery level, or when the electric-assisted bicycle is in the first sleep mode, the lighting control module, motor controller module and Bluetooth module inside the electric-assisted bicycle are all turned off according to external instructions, and the instrument module, BMS module and 4G module inside the electric-assisted bicycle are all put into deep sleep state so that the electric-assisted bicycle enters the second sleep mode.

[0062] Specifically, when the lighting control module 10, motor controller module 60, and Bluetooth module 30 in the electric-assisted bicycle are all turned off, the overall power consumption of the electric-assisted bicycle decreases to a second current power consumption value; when the instrument module 20 and BMS module 40 enter a deep sleep state, the overall power consumption of the electric-assisted bicycle decreases to another second current power consumption value; when the 4G module 50 enters a deep sleep state, the overall power consumption of the electric-assisted bicycle decreases to another second current power consumption value; these three second current power consumption values ​​are equal to the second preset current loss; the second preset current loss is less than the second preset current loss.

[0063] Specifically, the control instrument module 20 enters a deep sleep state, including: the CAN transceiver inside the control instrument module 20 is turned off; and the control instrument module 20 listens to the data on the CAN bus in real time to trigger wake-up.

[0064] Controlling the BMS module 40 to enter a deep sleep state includes: controlling the CAN transceiver inside the BMS module 40 to turn off, and controlling the BMS module 40 to send a fault signal to the CAN bus when the battery fails; and controlling the BMS module 40 to turn off data trigger wake-up from listening to the CAN bus (which can be activated via ACC).

[0065] All 4G modules 50 are controlled to enter a deep sleep state, including: controlling the CAN transceiver inside the 4G module 50 to turn off; controlling the 4G module 50 to report heartbeat data to the external platform at a preset frequency; and controlling the 4G module 50 to turn off data trigger wake-up from listening to the CAN bus (which can be woken up by APP command).

[0066] Additionally, it should be noted that when the electric-assist bicycle is in the second sleep mode, it can automatically switch to the normal riding mode based on the first external button command or the 4G external command (at this time, the Bluetooth module is turned off in the second sleep mode, so it can only be switched to the normal riding mode by the 4G external command); this enables the switching between different sleep modes and improves the flexibility of control.

[0067] S230. When the second sleep mode runs for a third preset time, or when the current battery level of the electric-assisted bicycle is less than the second preset battery level, or when the electric-assisted bicycle is in the second sleep mode, the lighting control module, motor controller module, Bluetooth module, instrument module, BMS module and 4G module inside the electric-assisted bicycle are turned off according to external instructions so that the electric-assisted bicycle enters the third sleep mode.

[0068] Specifically, the system de-energizes the lighting control module, motor controller module, Bluetooth module, instrument panel module, BMS module, and 4G module within the electric-assist bicycle, thereby shutting them down and putting the electric-assist bicycle into a third sleep mode. This reduces the overall power consumption of the electric-assist bicycle to a third preset current loss, which is less than the second preset current loss. Because the third preset current loss is relatively small, approaching the microampere level, the battery's discharge capacity is also small, allowing for long-term storage at 0% charge without damaging the battery cells. Furthermore, in the third sleep mode, the vehicle cannot be activated by the app, watch, or buttons; it can only be woken up by charging.

[0069] It should be noted that when the electric-assist bicycle is in the first sleep mode, it can also actively switch to the third sleep mode according to external commands; when the electric-assist bicycle is in normal riding mode, it can also actively switch to the third sleep mode according to external commands.

[0070] In other embodiments, when the electric-assist bicycle is in the third sleep mode, it actively switches to the first sleep mode based on the charging signal. Since the battery level is 0% when the electric-assist bicycle is in the third sleep mode, it can only actively switch to the first sleep mode based on the charging signal, and cannot be actively switched to the first sleep mode by external commands. This achieves the mutual switching between different sleep modes, improving control flexibility.

[0071] In this embodiment of the invention, the control of the electric-assist bicycle to enter different sleep modes is refined. By using multiple sleep modes that gradually reduce power consumption, the problem of battery cell damage caused by battery depletion in the electric-assist bicycle due to high power consumption in a single sleep mode is avoided, thus achieving protection of the battery cell.

[0072] Based on the same inventive concept, this embodiment of the invention also provides an electric-assisted bicycle, which includes at least a controller that executes the above embodiments. Since this embodiment includes a controller that executes the above embodiments, it also has the beneficial effects of the above embodiments, which will not be repeated here.

[0073] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
