[0002] The starting process of a fuel motorcycle usually requires the cooperation of multiple electronic components, such as energy storage batteries, electronic control units, and starter motors. The energy storage battery will lose energy due to wear and tear and the influence of environmental factors, which will cause the energy storage capacity to drop or the output voltage to drop, thus affecting the normal use of the electronic control unit.

[0039] See also Figure 1 , an embodiment of the present application provides a fuel motorcycle 100. The fuel motorcycle 100 includes a power control circuit 10, a vehicle body 20, an engine 30 and a starter motor 40. The power control circuit 10, the engine 30 and the starter motor 40 are all arranged on the vehicle body 20. The starter motor 40 is used to start the engine 30. The engine 30 is used to drive the vehicle body 20 and provide power for the movement of the vehicle body 20. The engine 30 can be, but is not limited to, an engine, a motor or a drive motor of a fuel motorcycle. The power control circuit 10 is used to supply power to the starter motor 40 and control the starter motor 40.

[0040] See also Figure 2 The power control circuit 10 includes a power supply 12 , a detection controller 14 , an electronic control unit 16 and a switch module 18 .

[0041] The power supply 12 is used to store electric energy and release the stored electric energy. The power supply 12 is used to output voltage.

[0042] The detection controller 14 is connected between the power supply 12 and the electronic control unit 16 , and is used to detect the output voltage of the power supply 12 in real time.

[0043] The electronic control unit 16 is connected to the starter motor 40 through the switch module 18, and the electronic control unit 16 is used to control the starter motor 40. The switch module 18 is also connected to the power supply 12 and the detection controller 14. The power supply 12 supplies power to the electronic control unit 16 through the detection controller 14. In some embodiments, when the switch module 18 is disconnected, the fuel motorcycle 100 can be in a stationary state; when the switch module 18 is turned on, the fuel motorcycle 100 can be in a waiting state.

[0044] In some embodiments, the electronic control unit 16 may further include a plurality of functional components, including basic functional components and specific functional components. Among them, the specific functional components may include, for example, a control functional component for the starter motor 40; the basic functional components may include, for example, other functional components such as a timer. Among them, the control functional component for the starter motor 40 is a functional component that requires a larger working voltage and has a higher requirement for the input voltage. For example, when the input voltage is low, it will trigger an automatic reset. It can be understood that the power consumption of these specific functional components is relatively large. Basic functional components such as timers are functional components that require a smaller working voltage and have a lower requirement for the input voltage. It can be understood that the power consumption of these basic functional components is relatively small.

[0045] When the switch module 18 is turned on and the detection controller 14 detects that the output voltage of the power supply 12 is less than the preset voltage threshold, the detection controller 14 converts the output voltage of the power supply 12 to the preset power supply voltage and outputs the preset power supply voltage to the electronic control unit 16 .

[0046] When the switch module 18 is turned on and the detection controller 14 detects that the output voltage of the power supply 12 is greater than or equal to the preset voltage threshold, the detection controller 14 outputs the output voltage of the power supply 12 to the electronic control unit 16 .

[0047] In some embodiments, when the switch module 18 is turned on, that is, when the fuel motorcycle 100 is in the waiting state, when the detection controller 14 detects that the output voltage of the power supply 12 is less than the preset voltage threshold, it indicates that the output voltage of the power supply 12 is low, and the power supply of the power supply 12 is abnormal, which is not conducive to the normal operation of the electronic control unit 16. For example, when the input voltage of the electronic control unit 16 is low, it will trigger an automatic reset. Therefore, when the switch module 18 is turned on and the output voltage of the power supply 12 is low, the fuel motorcycle 100 is in the waiting state, and the detection controller 14 increases the output voltage of the power supply 12 to the preset power supply voltage to ensure that the preset power supply voltage provided to the electronic control unit 16 meets the normal working voltage requirements, so as to ensure the normal operation of the electronic control unit 16, so that the electronic control unit 16 can normally control the starter motor 40, and ensure the starting stability of the fuel motorcycle 100.

[0048] In some embodiments, when the switch module 18 is turned on, that is, when the fuel motorcycle 100 is in the waiting state, when the detection controller 14 detects that the output voltage of the power supply 12 is greater than or equal to the preset voltage threshold, it indicates that the output voltage of the power supply 12 is high, the power supply of the power supply 12 is normal, and the electronic control unit 16 can work normally. Therefore, when the switch module 18 is turned on and the output voltage of the power supply 12 is high, the fuel motorcycle 100 is in the waiting state, and the output voltage of the power supply 12 is provided to the electronic control unit 16 through the detection controller 14, so that the electronic control unit 16 works normally, so that the electronic control unit 16 controls the starter motor 40 normally, and ensures the starting stability of the fuel motorcycle 100.

[0049] In some embodiments, the detection controller 14 is also used to detect the remaining power of the power supply 12 .

[0050] When the switch module 18 is disconnected and the detection controller 14 detects that the remaining power of the power supply 12 is less than the preset power threshold, the detection controller 14 disconnects the preset power supply from the power supply 12 to the electronic control unit 16 .

[0051] When the switch module 18 is disconnected and the detection controller 14 detects that the output voltage of the power supply 12 is less than the preset voltage threshold, the detection controller 14 disconnects the preset power supply from the power supply 12 to the electronic control unit 16 .

[0052] In some embodiments, when the switch module 18 is disconnected, that is, when the fuel motorcycle 100 is in a stationary state, when the detection controller 14 detects that the remaining power of the power supply 12 is less than the preset power threshold, it indicates that the remaining power of the power supply 12 is insufficient; or when the detection controller 14 detects that the output voltage of the power supply 12 is less than the preset voltage threshold, it indicates that the output voltage of the power supply 12 is low, indicating that the power supply of the power supply 12 is abnormal, and the detection controller 14 disconnects the preset power supply from the power supply 12 to the electronic control unit 16, which can protect the power supply 12. In some embodiments, the preset power supply from the power supply 12 to the electronic control unit 16 can be power supply to the basic functional components of the electronic control unit 16, for example, power supply to basic functional components such as timers, that is, functional components with low power consumption in the electronic control unit 16.

[0053] When the switch module 18 is disconnected and the detection controller 14 detects that the remaining power of the power supply 12 is greater than or equal to the preset power threshold, the detection controller 14 still maintains the preset power supply from the power supply 12 to the electronic control unit 16 .

[0054] In some embodiments, when the switch module 18 is disconnected, that is, the fuel motorcycle 100 is in a stationary state, when the detection controller 14 detects that the remaining power of the power supply 12 is greater than or equal to a preset power threshold, it indicates that the remaining power of the power supply 12 is sufficient, and the detection controller 14 still maintains the preset power supply of the power supply 12 to the electronic control unit 16, that is, when the fuel motorcycle 100 is in a stationary state, the power supply 12 still maintains power to the basic functional components in the electronic control unit 16.

[0055] When the switch module 18 is turned on and the detection controller 14 detects that the remaining power of the power supply 12 is less than the preset power threshold, the detection controller 14 turns on the power supply 12 to supply power to the electronic control unit 16 .

[0056] In some embodiments, when the switch module 18 is turned on, that is, the fuel motorcycle 100 is in a waiting-to-start state, the detection controller 14 detects that the remaining power of the power supply 12 is less than a preset power threshold and the detection controller 14 turns on the power supply 12 to supply power to the electronic control unit 16 to ensure that the electronic control unit 16 obtains power, thereby the electronic control unit 16 controls the starter motor 40 to ensure the starting stability of the fuel motorcycle 100.

[0057] When the switch module 18 is turned on and the detection controller 14 detects that the remaining power of the power supply 12 is greater than or equal to the preset power threshold, the detection controller 14 maintains the power supply 12 supplying power to the electronic control unit 16. When the detection controller 14 detects that the output voltage of the power supply 12 is less than the preset voltage threshold, the detection controller 14 converts the output voltage value of the power supply 12 to the preset power supply voltage, and outputs the preset power supply voltage to the electronic control unit 16.

[0058] In some embodiments, when the switch module 18 is turned on, that is, the fuel motorcycle 100 is in a waiting-to-start state, when the remaining power of the power supply 12 is greater than or equal to a preset power threshold, it indicates that the remaining power of the power supply 12 is sufficient, and the detection controller 14 detects the output voltage of the power supply 12. When the detection controller 14 detects that the output voltage of the power supply 12 is less than the preset voltage threshold, the output voltage of the power supply 12 is increased to the preset power supply voltage through the detection controller 14 to ensure that the preset power supply voltage provided to the electronic control unit 16 meets the normal working voltage requirements to ensure the normal operation of the electronic control unit 16, so that the electronic control unit 16 can normally control the starter motor 40 to ensure the starting stability of the fuel motorcycle 100.

[0059] Please also read Figure 3, the power supply 12 has a positive electrode B+ and a negative electrode B-. The power supply 12 can output voltage through the positive electrode B+ and the negative electrode B-.

In some embodiments, the power supply 12 can be, but is not limited to, a 12V rechargeable and dischargeable storage battery. The negative electrode B- of the power supply 12 can be grounded.

[0060] The power control circuit 10 also includes a first insurance unit 122. The first insurance unit 122 is connected to the positive electrode B+ of the power supply 12 for overvoltage protection. For example, when the output voltage of the power supply 12 is too large, the first insurance unit 122 can disconnect the external output line of the power supply 12 to protect other electronic components.

[0061] The detection controller 14 has a detection end and an output end. The detection end of the detection controller 14 includes a detection positive pole IN+ and a detection negative pole IN-, the detection positive pole IN+ is connected to the positive pole B+ of the power supply 12 through the first insurance unit 122, and the detection negative pole IN- is connected to the negative pole B- of the power supply 12. The detection controller 14 is used to detect the remaining power and output voltage of the power supply 12 by detecting the positive pole IN+ and the negative pole IN-.

[0062] The power control circuit 10 further includes a second insurance unit 142. The second insurance unit 142 is connected in series to the output positive electrode OUT+ of the detection controller 14. The second insurance unit 142 is used for overvoltage protection. For example, when the power supply voltage at the output end of the detection controller 14 is too large, the second insurance unit 142 can disconnect the external output line of the detection controller 14 to protect other electronic components.

[0063] The electronic control unit 16 has a controlled end and a control end. The controlled end of the electronic control unit 16 includes a controlled positive pole U+, a controlled negative pole U- and a controlled pole U0.

In some embodiments, when the ignition switch 181 is disconnected, the fuel motorcycle 100 can be in a stationary state, that is, a state in which the electric door lock is closed; when the ignition switch 181 is turned on, the fuel motorcycle 100 can be in a state to be started, that is, a state in which the electric door lock is opened.

[0067] One end of the flameout switch 182 is connected to the control positive electrode C+ of the control end of the electronic control unit 16, and the other end of the flameout switch 182 is connected to the output positive electrode OUT+ of the detection controller 14 through the ignition switch 181 and the second insurance unit 142.

In some embodiments, the flameout switch 182 can be an engine flameout switch, which can control the circuit of the starter relay 184 and the auxiliary relay 185, and can be installed on the handlebar of the fuel motorcycle 100 for the operator to operate to realize the disconnection or conduction of the flameout switch 182. In some embodiments, the flameout switch 182 can be used to switch the fuel motorcycle 100 to the flameout state when the engine is in the working state (or started state).

[0071] When the ignition switch 181 is disconnected, that is, when the fuel motorcycle 100 is in a stationary state, the detection controller 14 detects the remaining power and output voltage of the power supply 12 by detecting the positive electrode IN+ and the negative electrode IN-. When the detection controller 14 detects that the remaining power of the power supply 12 is less than the preset power threshold, the detection controller 14 disconnects the preset power supply from the power supply 12 to the electronic control unit 16, that is, the output end of the detection controller 14 does not output the power supply voltage, and shuts off the power supply to the electronic control unit 16, the switch module 18 and the starter motor 40. In some embodiments, the preset power threshold can be, but is not limited to, 0.5, that is, the ratio of the remaining power of the power supply 12 to the nominal capacity is 0.5. It can be understood that the preset power threshold can be different values ​​depending on the model or performance of the motorcycle, and this application is not limited thereto.

[0072] When the ignition switch 181 is disconnected, that is, when the fuel motorcycle 100 is in a stationary state, when the detection controller 14 detects that the output voltage of the power supply 12 is less than the preset voltage threshold, the detection controller 14 disconnects the preset power supply of the power supply 12 to the electronic control unit 16, that is, the output end of the detection controller 14 does not output the power supply voltage, and the power supply to the electronic control unit 16, the switch module 18 and the starter motor 40 is turned off. In some embodiments, the power supply 12 can be, but is not limited to, a 12V rechargeable and dischargeable storage battery, and the preset voltage threshold can be, but is not limited to, 10.5V. It can be understood that the preset voltage threshold can be different values ​​depending on the model or performance of the motorcycle, and this application is not limited thereto.

[0073] When the ignition switch 181 is turned on, the fuel motorcycle 100 can be in a waiting state. When the detection controller 14 detects that the remaining power of the power supply 12 is less than the preset power threshold, and the output voltage is less than the preset voltage threshold, the detection controller 14 converts the output voltage of the power supply 12 to the preset power voltage, and outputs the power voltage through the output positive pole OUT+ and the output negative pole OUT- of the output end. The detection controller 14 outputs the power voltage to the controlled positive pole U+, the controlled negative pole U- and the controlled pole U0 of the control end of the electronic control unit 16 through the output positive pole OUT+ and the output negative pole OUT- of the output end, and the electronic control unit 16 obtains the working voltage. After the flameout switch 182 is turned on, the electronic control unit 16 is in a start-allowed state. After the start switch 183 is turned on, the electronic control unit 16 can control the auxiliary relay 185 to work, and then control the start relay 184 to work, so that the electronic control unit 16 controls the start of the starter motor 40.

[0074] When the ignition switch 181 is turned off, when the detection controller 14 detects that the remaining power of the power supply 12 is greater than or equal to the preset power threshold, the detection controller 14 still maintains the preset power supply from the power supply 12 to the electronic control unit 16 .

[0075] When the switch module 18 is turned on, the detection controller 14 detects that the remaining power of the power supply 12 is greater than or equal to the preset power threshold, and the detection controller 14 detects that the output voltage of the power supply 12 is less than the preset voltage threshold. The detection controller 14 converts the output voltage of the power supply 12 to the preset power supply voltage, and outputs the preset power supply voltage through the output positive pole OUT+ and the output negative pole OUT- of the output end. The detection controller 14 outputs the preset power supply voltage to the controlled positive pole U+, the controlled negative pole U- and the controlled pole U0 of the control end of the electronic control unit 16 through the output positive pole OUT+ and the output negative pole OUT- of the output end, and the electronic control unit 16 obtains the working voltage. After the ignition off switch 182 is turned on, the electronic control unit 16 is in the start-up permission state. After the start switch 183 is turned on, the electronic control unit 16 can control the auxiliary relay 185 to work, and then control the start relay 184 to work, so that the electronic control unit 16 controls the start of the starter motor 40.

[0076] In some embodiments, when the detection controller 14 detects that the remaining power of the power supply 12 is greater than or equal to the preset power threshold, and the output voltage is less than the preset voltage threshold, it indicates that the remaining power of the power supply 12 is sufficient, but the output voltage is low, which is not conducive to the normal operation of the electronic control unit 16. The detection controller 14 converts the output voltage of the power supply 12 to a preset power supply voltage, and the preset power supply voltage is greater than the output voltage of the power supply 12. It can be understood that the preset power supply voltage can be the normal working voltage of the electronic control unit 16 (for example, 12V). When the output voltage of the power supply 12 is low (for example, less than 10.5V), the detection controller 14 outputs the preset power supply voltage to the electronic control unit 16, which can ensure that the electronic control unit 16 can obtain a better power supply voltage to work normally, thereby normally controlling the starter motor 40, and ensuring the stability of the start of the fuel motorcycle 100.

[0077] See also Figure 4 , is a flow chart of a method for starting a fuel motorcycle provided in an embodiment of the present application. For example, Figure 4 The starting method of the fuel motorcycle shown can be executed by the fuel motorcycle 100 of the above embodiment, and includes the following steps.

[0078] Step S411, when the ignition switch is turned off, the fuel motorcycle is in a stationary state.

[0079] In some embodiments, when the ignition switch 181 is turned off, the fuel motorcycle 100 is in a stationary state.

[0080] Step S412: the detection controller detects whether the output voltage of the power supply is less than a preset voltage threshold.

[0081] In some embodiments, when the ignition switch 181 is turned off, that is, the fuel motorcycle 100 is in a stationary state, the detection controller 14 detects whether the output voltage of the power supply 12 is less than a preset voltage threshold. When the detection controller 14 detects that the output voltage of the power supply 12 is less than the preset voltage threshold, it indicates that the output voltage of the power supply 12 is low, and step S414 is executed; when the detection controller 14 detects that the output voltage of the power supply 12 is greater than or equal to the preset voltage threshold, it indicates that the output voltage of the power supply 12 is high, and step S413 is executed.

[0082] Step S413: the detection controller detects whether the remaining power of the power supply is less than a preset power threshold.

[0083] In some embodiments, when the ignition switch 181 is turned off, that is, the fuel motorcycle 100 is in a stationary state, the detection controller 14 detects whether the remaining power of the power supply 12 is less than a preset power threshold. When the detection controller 14 detects that the remaining power of the power supply 12 is less than the preset power threshold, it indicates that the remaining power of the power supply 12 is insufficient, and step S414 is executed; when the detection controller 14 detects that the remaining power of the power supply 12 is greater than or equal to the preset power threshold, it indicates that the remaining power of the power supply 12 is sufficient, and step S415 is executed.

[0084] It can be understood that the execution order of step S412 and step S413 can be swapped or performed simultaneously, and this application does not limit this.

[0085] Step S414: the detection controller disconnects the power supply to the preset power supply of the electronic control unit.

[0086] In some embodiments, the detection controller 14 disconnects the preset power supply from the power supply 12 to the electronic control unit 16 to protect the power supply 12. Specifically, the detection controller 14 disconnects the external output, that is, disconnects the path between the output positive pole OUT+ and the output negative pole OUT- and the controlled positive pole U+ and the controlled negative pole U- of the electronic control unit 16, so that the detection controller 14 does not provide the preset power supply to the electronic control unit 16, thereby disconnecting the power supply to the basic functional components in the electronic control unit 16, so as to shut down the output of the power supply 12 and protect the power supply 12. In some embodiments, the preset power supply from the power supply 12 to the electronic control unit 16 can be the power supply to the basic functional components of the electronic control unit 16, for example, the power supply to the basic functional components such as the timer, that is, the functional components with low power consumption in the electronic control unit 16.

[0087] Step S415: the detection controller maintains the power supply to supply a preset power to the electronic control unit.

[0088] In some embodiments, the detection controller 14 maintains the preset power supply from the power supply 12 to the electronic control unit 16. The detection controller 14 provides the preset power supply to the electronic control unit 16 through the paths between the output positive pole OUT+ and the output negative pole OUT- and the controlled positive pole U+ and the controlled negative pole U- of the electronic control unit 16, respectively, so as to maintain the power supply to the basic functional components (such as the timer, etc.) in the electronic control unit 16 and maintain the normal operation of the basic functional components. Since the power consumption of specific functional components (such as the control functional components for the starter motor 40) in the electronic control unit 16 is relatively large, while the power consumption of the basic functional components (such as the timer, etc.) is relatively small, that is, at this time, the detection controller 14 only maintains a small current output, which can protect the power supply 12.

[0089] Step S416, when the ignition switch is turned on, the detection controller converts the output voltage of the power supply to a preset power supply voltage, and outputs the preset power supply voltage to the electronic control unit.

[0090] In some embodiments, after step S414, step S416 is executed, and when the ignition switch 181 is turned on, the fuel motorcycle 100 can be in a waiting state, and the detection controller 14 converts the output voltage of the power supply 12 to a preset power supply voltage, and outputs the preset power supply voltage to the electronic control unit 16 through the path between the output positive pole OUT+ of the detection controller 14, the turned-on ignition switch 181 and the controlled pole U0 of the electronic control unit 16, and the path between the output positive pole OUT+ and the output negative pole OUT- of the detection controller 14 and the controlled positive pole U+ and the controlled negative pole U- of the electronic control unit 16, so that the electronic control unit 16 can obtain the voltage for normal operation. That is, the controlled positive pole U+, the controlled negative pole U- and the controlled pole U0 of the electronic control unit 16 can all obtain the input preset power supply voltage, and the specific functional components and basic functional components of the electronic control unit 16 can all work normally. It can be understood that the preset power supply voltage is greater than the output voltage of the power supply 12. The preset power supply voltage can be the normal working voltage of the electronic control unit 16 (for example, 12V). When the output voltage of the power supply 12 is low (for example, less than 10.5V), the detection controller 14 outputs the preset power supply voltage to the electronic control unit 16, which can ensure that the electronic control unit 16 can obtain a better power supply voltage to work normally.

[0091] Step S417: when the ignition switch is turned on, the detection controller provides the output voltage of the power supply to the electronic control unit.

[0092] In some embodiments, after step S415, step S417 is executed, and when the ignition switch 181 is turned on, the fuel motorcycle 100 can be in a waiting state, and the detection controller 14 outputs the output voltage of the power supply 12 to the electronic control unit 16 through the output positive pole OUT+ of the detection controller 14, the turned-on ignition switch 181 and the controlled pole U0 of the electronic control unit 16, and the output positive pole OUT+ and the output negative pole OUT- of the detection controller 14 and the controlled positive pole U+ and the controlled negative pole U- of the electronic control unit 16, respectively, so that the electronic control unit 16 can obtain the voltage for normal operation. That is, the controlled positive pole U+, the controlled negative pole U- and the controlled pole U0 of the electronic control unit 16 can all obtain the input working voltage, and the specific functional components and basic functional components of the electronic control unit 16 can all work normally. It can be understood that when the output voltage of the power supply 12 is greater than or equal to a preset voltage threshold (for example, greater than or equal to 10.5V), the detection controller 14 outputs the output voltage of the power supply 12 to the electronic control unit 16, which can ensure that the electronic control unit 16 can obtain a better power supply voltage to operate normally.

[0093] Step S418, when the ignition off switch and the start switch are turned on, the electronic control unit controls the auxiliary relay and the start relay to be turned on, and controls the start of the starter motor, thereby controlling the start of the fuel motorcycle.

[0094] In some embodiments, after step S416 or S417, step S418 is executed, when the ignition off switch 182 is turned on, the electronic control unit 16 is in the start-up permission state, when the start switch 183 is turned on, the first and second ends of the auxiliary relay 185 have current input to turn on the auxiliary relay 185, and the third end of the auxiliary relay 185 obtains current input from the output positive electrode OUT+ of the detection controller 14 through the ignition switch 181 and the second insurance unit 142, and outputs current through the fourth end. Then the second end of the start relay 184 obtains current input through the fourth end of the auxiliary relay 185, the start relay 184 is turned on, the third end of the start relay 184 obtains current input through the positive electrode B+ of the power supply voltage 12, and outputs current to the starter motor 40 through the fourth end, and then the starter motor 40 starts the engine 30, so that the fuel motorcycle 100 starts.

[0095] During the starting process of the fuel motorcycle 100, when the detection controller 14 detects that the output voltage of the power supply 12 is less than the preset voltage threshold, the detection controller 14 converts the output voltage of the power supply 12 to the preset power supply voltage and outputs it to the electronic control unit 16; when the detection controller 14 detects that the output voltage of the power supply 12 is greater than or equal to the preset voltage threshold, the detection controller 14 outputs the output voltage of the power supply 12 to the electronic control unit 16, which can ensure that the electronic control unit 16 can obtain a better power supply voltage to work normally, thereby normally controlling the starter motor 40, ensuring the stability of the starting of the fuel motorcycle 100.

[0096] See also Figure 5 , is a flow chart of a method for starting a fuel motorcycle provided by another embodiment of the present application. For example, Figure 5 The starting method of the fuel motorcycle shown in the figure can be executed by the fuel motorcycle 100 of the above embodiment. Figure 4 After step S418 of the method for starting a fuel motorcycle, the method for starting a fuel motorcycle may further include the following steps.

[0097] S419, the detection controller detects whether the output voltage of the power supply is less than a preset voltage threshold.

[0098] In some embodiments, when the starter motor 40 receives current and starts working, the output voltage of the power supply 12 may drop sharply, and the detection controller 14 detects whether the output voltage of the power supply 12 is less than the preset voltage threshold. When the detection controller 14 detects that the output voltage of the power supply 12 is less than the preset voltage threshold, it indicates that the output voltage of the power supply 12 is low, which may affect the normal operation of the electronic control unit 16 (for example, too low a voltage may trigger the automatic reset of the electronic control unit 16), and step S420 is executed at this time; when the detection controller 14 detects that the output voltage of the power supply 12 is greater than or equal to the preset voltage threshold, it indicates that the output voltage of the power supply 12 is high, and step S421 is executed.

[0099] In step S420, the detection controller converts the output voltage of the power supply to a preset power supply voltage, and outputs the preset power supply voltage to the electronic control unit.

[0100] In some embodiments, the detection controller 14 converts the output voltage of the power supply 12 to a preset power supply voltage, and outputs the preset power supply voltage to the electronic control unit 16 through the path between the output positive electrode OUT+ of the detection controller 14, the turned-on ignition switch 181 and the controlled electrode U0 of the electronic control unit 16, and the path between the output positive electrode OUT+ and the output negative electrode OUT- of the detection controller 14 and the controlled positive electrode U+ and the controlled negative electrode U- of the electronic control unit 16, so that the electronic control unit 16 can obtain a normal working voltage, thereby avoiding the electronic control unit 16 from working abnormally due to insufficient power supply (for example, too low a voltage may trigger the automatic reset of the electronic control unit 16). It can be understood that the preset power supply voltage is greater than the output voltage of the power supply 12, and the preset power supply voltage can be the normal working voltage of the electronic control unit 16 (for example, 12V). When the output voltage of the power supply 12 is low (for example, less than 10.5V), the detection controller 14 outputs the preset power supply voltage to the electronic control unit 16, which can ensure that the electronic control unit 16 can obtain a better power supply voltage to work normally.

[0101] Step S421: the detection controller provides the output voltage of the power supply to the electronic control unit.

[0102] In some embodiments, the detection controller 14 outputs the output voltage of the power supply 12 to the electronic control unit 16 through the path between the output positive electrode OUT+ of the detection controller 14, the turned-on ignition switch 181 and the controlled electrode U0 of the electronic control unit 16, and the path between the output positive electrode OUT+ and the output negative electrode OUT- of the detection controller 14 and the controlled positive electrode U+ and the controlled negative electrode U- of the electronic control unit 16, so that the electronic control unit 16 can obtain a voltage for normal operation. It can be understood that when the output voltage of the power supply 12 is greater than or equal to a preset voltage threshold (for example, greater than or equal to 10.5V), the detection controller 14 outputs the output voltage of the power supply 12 to the electronic control unit 16, which can ensure that the electronic control unit 16 can obtain a better supply voltage for normal operation.

[0103] When the starter motor 40 receives current and starts working, the output voltage of the power supply 12 may drop sharply. The detection controller 14 detects whether the output voltage of the power supply 12 is less than the preset voltage threshold. When the detection controller 14 detects that the output voltage of the power supply 12 is less than the preset voltage threshold, the detection controller 14 converts the output voltage of the power supply 12 to the preset power supply voltage and outputs the preset power supply voltage to the electronic control unit 16; when the detection controller 14 detects that the output voltage of the power supply 12 is greater than or equal to the preset voltage threshold, the detection controller 14 provides the output voltage of the power supply 12 to the electronic control unit 16. This ensures that the electronic control unit 16 can obtain a better power supply voltage and avoid abnormal working conditions.

For example, Figure 6 The starting method of the fuel motorcycle shown is the same as Figure 4 The starting method of the fuel motorcycle shown is roughly the same, but Figure 4 The order of step S412 and step S413 is swapped, and the other steps remain the same. Figure 6 The starting method of the fuel motorcycle shown may also include the following steps.

[0105] Step S612: the detection controller detects whether the remaining power of the power supply is less than a preset power threshold.

[0106] In some embodiments, the detection controller 14 detects whether the remaining power of the power supply 12 is less than a preset power threshold. When the detection controller 14 detects that the remaining power of the power supply 12 is less than the preset power threshold, it indicates that the remaining power of the power supply 12 is insufficient, and step S614 is executed; when the detection controller 14 detects that the remaining power of the power supply 12 is greater than or equal to the preset power threshold, it indicates that the remaining power of the power supply 12 is sufficient, and step S613 is executed.

[0107] Step S613: the detection controller detects whether the output voltage of the power supply is less than a preset voltage threshold.

[0108] In some embodiments, the detection controller 14 detects whether the output voltage of the power supply 12 is less than a preset voltage threshold. When the detection controller 14 detects that the output voltage of the power supply 12 is less than the preset voltage threshold, it indicates that the output voltage of the power supply 12 is low, and step S614 is executed; when the detection controller 14 detects that the output voltage of the power supply 12 is greater than or equal to the preset voltage threshold, it indicates that the output voltage of the power supply 12 is high, and step S615 is executed.
