[0002] In the starting process of the fuel motorcycle, multiple electronic components are usually required to cooperate, such as energy storage battery, electronic control unit and starting motor. Among them, the energy storage capacity of the energy storage battery is reduced or the output voltage is reduced due to the loss with use and the influence of environmental factors, which affects the normal use of the electronic control unit. Generally, the electronic control unit has a higher voltage requirement, and when the input voltage is low, it will trigger an automatic reset, thereby affecting the starting of the motorcycle. In addition, at the starting moment of the starting motor, the power consumption is large, which will cause the voltage of the energy storage battery to drop sharply at the moment, which will also affect the normal use of the electronic control unit, and further affect the starting of the motorcycle.

[0039] Referring now to the drawings Figure 1 The embodiments of the present application provide a fuel motorcycle 100. The fuel motorcycle 100 comprises a power supply control circuit 10, a vehicle body 20, an engine 30 and a starting motor 40. The power supply control circuit 10, the engine 30 and the starting motor 40 are all arranged on the vehicle body 20. The starting 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 of a fuel motorcycle, an electric motor or a driving motor. The power supply control circuit 10 is used to supply power to and control the starting motor 40.
[0040] Referring now to the drawings Figure 2 The power supply control circuit 10 comprises 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 and release electrical 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. The detection controller 14 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 starting motor 40 through the switch module 18. The electronic control unit 16 is used to control the starting 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 off, the fuel motorcycle 100 can be in a static state; when the switch module 18 is on, the fuel motorcycle 100 can be in a starting state.
[0044] In some embodiments, the electronic control unit 16 can further include a plurality of functional components, including basic functional components and specific functional components. Among them, the specific functional components can include, for example, a control functional component for starting the motor 40; the basic functional components can include, for example, a timer and other functional components. Among them, the control functional component for starting the motor 40 is a functional component that requires a large 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, and it can be understood that the power consumption of these specific functional components is large. The basic functional components such as timers are functional components that require a small working voltage, and have a lower requirement for the input voltage, and it can be understood that the power consumption of these basic functional components is small.
[0045] When the switch module 18 is turned on, and 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.
[0046] When the switch module 18 is turned on, and 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.
[0047] In some embodiments, when the switch module 18 is turned on, that is, the fuel motorcycle 100 is in a state of waiting to start, 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 work of the electronic control unit 16, for example, the input voltage of the electronic control unit 16 is low, which 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 a state of waiting to start, and the output voltage of the power supply 12 is converted to the preset power supply voltage by the detection controller 14, to ensure that the preset power supply voltage provided to the electronic control unit 16 meets the normal working voltage requirement, to ensure the normal work of the electronic control unit 16, so that the electronic control unit 16 controls the starting motor 40 normally, and ensures the starting stability of the fuel motorcycle 100.
[0048] In some embodiments, when the switch module 18 is turned on, i.e. the fuel motorcycle 100 is in the state of waiting for starting, the detection controller 14 detects that the output voltage of the power supply 12 is greater than or equal to the preset voltage threshold, indicating that the output voltage of the power supply 12 is high, the power supply of the power supply 12 is normal, and the normal work of the electronic control unit 16 can be ensured. 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 state of waiting for starting, 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, thereby ensuring the normal control of the starting motor 40 by the electronic control unit 16 and the stability of the starting 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 turned off, 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 off the preset power supply of the power supply 12 to the electronic control unit 16.
[0051] When the switch module 18 is turned off, 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 turns off the preset power supply of the power supply 12 to the electronic control unit 16.
[0052] In some embodiments, when the switch module 18 is turned off, i.e. the fuel motorcycle 100 is in the state of waiting for starting, the detection controller 14 detects that the remaining power of the power supply 12 is less than the preset power threshold, indicating that the remaining power of the power supply 12 is insufficient; or the detection controller 14 detects that the output voltage of the power supply 12 is less than the preset voltage threshold, indicating 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 turns off the preset power supply of the power supply 12 to the electronic control unit 16, which can protect the power supply 12. In some embodiments, the preset power supply of 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, such as the power supply to the timer and other basic functional components, i.e. the power supply to the functional components with small power consumption in the electronic control unit 16.
[0053] When the switch module 18 is turned off, 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 of the power supply 12 to the electronic control unit 16.
[0054] In some embodiments, when the switch module 18 is off, i.e. the fuel motorcycle 100 is in a static state, 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, indicating that the remaining power of the power supply 12 is sufficient, the detection controller 14 still maintains the preset power supply of the power supply 12 to the electronic control unit 16, i.e. the power supply of the power supply 12 to the basic functional components in the electronic control unit 16 is still maintained when the fuel motorcycle 100 is in a static state.
[0055] When the switch module 18 is on, and 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 turns on the power supply of the power supply 12 to the electronic control unit 16.
[0056] In some embodiments, when the switch module 18 is on, i.e. the fuel motorcycle 100 is in a state of waiting to start, when the detection controller 14 detects that the remaining power of the power supply 12 is less than the preset power threshold, and the detection controller 14 turns on the power supply of the power supply 12 to the electronic control unit 16, to ensure that the electronic control unit 16 obtains power supply, so that the control of the electronic control unit 16 to the starting motor 40 ensures the stability of the starting of the fuel motorcycle 100.
[0057] When the switch module 18 is on, and 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 maintains the power supply of the power supply 12 to the electronic control unit 16, and 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.
[0058] In some embodiments, when the switch module 18 is on, i.e. the fuel motorcycle 100 is in a state of waiting to start, when the remaining power of the power supply 12 is greater than or equal to the preset power threshold, indicating that the remaining power of the power supply 12 is sufficient, the detection controller 14 detects the output voltage of the power supply 12, and 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 converted to the preset power supply voltage by the detection controller 14, to ensure that the preset power supply voltage provided to the electronic control unit 16 meets the normal working voltage requirement, to ensure the normal work of the electronic control unit 16, so that the electronic control unit 16 controls the starting motor 40 normally, to ensure the stability of the starting of the fuel motorcycle 100.
[0059] Please see Figure 3The power supply 12 has a positive pole B+ and a negative pole B-. The power supply 12 can output a voltage through the positive pole B+ and the negative pole B-. The detection controller 14 detects the state of charge (SOC) of the power supply 12, which can be the proportion of the available charge in the power supply 12 to the nominal capacity. In some embodiments, the power supply 12 can be, but is not limited to, a 12V rechargeable battery. The negative pole B- of the power supply 12 can be grounded.
[0060] The power supply control circuit 10 further includes a first fuse unit 122. The first fuse unit 122 is connected to the positive pole 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 fuse 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 fuse unit 122, and the detection negative pole IN- is connected to the negative pole B- of the power supply 12.

The output end of the detection controller 14 includes an output positive pole OUT+ and an output negative pole OUT-.
[0062] The power supply control circuit 10 further includes a second fuse unit 142. The second fuse unit 142 is connected in series to the output positive pole OUT+ of the detection controller 14. The second fuse unit 142 is used for overvoltage protection. For example, when the supply voltage of the output end of the detection controller 14 is too large, the second fuse 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. The controlled positive pole U+ is connected to the output positive pole OUT+ of the detection controller 14 through the second fuse unit 142.

The electronic control unit 16 receives the power supply voltage of the output end of the detection controller 14 through the controlled positive pole U+ and the controlled negative pole U-. In some embodiments, the controlled positive pole U+ of the controlled end of the electronic control unit 16 can be connected to basic functional components such as a timer. The controlled pole U0 of the controlled end of the electronic control unit 16 can be connected to control functional components of the starting motor 40. The basic functional components such as the timer of the electronic control unit 16 can obtain working voltage from the detection controller 14 through the controlled positive pole U+ and the controlled negative pole U-. The control functional components of the starting motor 40 of the electronic control unit 16 can obtain working voltage from the detection controller 14 through the controlled pole U0 and the controlled negative pole U-.
[0064] The electronic control unit 16 is used to control the starting motor 40. In some embodiments, the electronic control unit 16 can be, but is not limited to, an Electronic Control Unit (ECU) of a motor vehicle, a control center of a motorcycle, and is integrated with functions such as processing, storage, input / output, analog-to-digital conversion, shaping, driving, etc. The control end of the electronic control unit 16 includes a control positive pole C+ and a control negative pole C-.

[0066] The ignition switch 181 is connected in series with the second fuse unit 142 to the output positive pole OUT+ of the detection controller 14. In some embodiments, the ignition switch 181 can be a lock of the fuel motorcycle 100. A key or the like can be used as a medium for a user to operate the ignition switch 181 to achieve the disconnection or conduction of the ignition switch 181. In some embodiments, when the ignition switch 181 is disconnected, the fuel motorcycle 100 can be in a static state, i.e., a state in which the lock is closed. When the ignition switch 181 is conducted, the fuel motorcycle 100 can be in a starting state, i.e., a state in which the lock is opened.
[0067] One end of the ignition switch 181 is connected to the control positive pole C+ of the control terminal of the electronic control unit 16, and the other end of the ignition switch 181 is connected to the output positive pole OUT+ of the detection controller 14 through the second fuse unit 142.

[0070] The starting relay 184 is connected between the auxiliary relay 185 and the starting motor 40, and is used to control the circuit between the electronic control unit 16 and the starting motor 40.

[0071] When the ignition switch 181 is off, i.e. the fuel motorcycle 100 is in a static state, the detection controller 14 detects the remaining capacity and output voltage of the power supply 12 through the positive electrode IN+ and the negative electrode IN-. When the detection controller 14 detects that the remaining capacity of the power supply 12 is less than a preset capacity threshold, the detection controller 14 disconnects the preset power supply of the power supply 12 to the electronic control unit 16, i.e. 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 starting motor 40 is turned off. In some embodiments, the preset capacity threshold can be but is not limited to 0.5, i.e. the proportion of the remaining capacity of the power supply 12 to the nominal capacity is 0.5. It can be understood that the preset capacity threshold can be different values according to different models or performances of the motorcycle, which is not limited by the present application.
[0072] When the ignition switch 181 is off, i.e. the fuel motorcycle 100 is in a static state, when the detection controller 14 detects that the output voltage of the power supply 12 is less than a preset voltage threshold, the detection controller 14 disconnects the preset power supply of the power supply 12 to the electronic control unit 16, i.e. 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 starting motor 40 is turned off. In some embodiments, the power supply 12 can be but is not limited to a 12V chargeable 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 according to different models or performances of the motorcycle, which is not limited by the present application.
[0073] When the ignition switch 181 is on, the fuel motorcycle 100 can be in a starting state, when the detection controller 14 detects that the remaining capacity of the power supply 12 is less than a preset capacity threshold and the output voltage is less than a preset voltage threshold, the detection controller 14 converts the output voltage of the power supply 12 to a preset power supply voltage and outputs the power supply voltage through the output positive electrode OUT+ and the output negative electrode OUT- of the output end. The detection controller 14 outputs the power supply voltage through the output positive electrode OUT+ and the output negative electrode OUT- of the output end to the controlled positive electrode U+, the controlled negative electrode U- and the controlled electrode U0 of the control end of the electronic control unit 16, and the electronic control unit 16 obtains the working voltage. After the ignition switch 182 is turned on, the electronic control unit 16 is in an allowed starting state, and after the starting switch 183 is turned on, the electronic control unit 16 can control the auxiliary relay 185 to work, and then control the starting relay 184 to work, so that the electronic control unit 16 controls the starting of the starting motor 40.
[0074] When the ignition switch 181 is off, when the detection controller 14 detects that the remaining capacity of the power supply 12 is greater than or equal to a preset capacity threshold, the detection controller 14 still maintains the preset power supply of the power supply 12 to the electronic control unit 16.
[0075] When the switch module 18 is turned on, 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 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 through the output positive electrode OUT+ and the output negative electrode OUT- of the output terminal. The detection controller 14 outputs the preset power supply voltage through the output positive electrode OUT+ and the output negative electrode OUT- of the output terminal to the controlled positive electrode U+, the controlled negative electrode U-, and the controlled electrode U0 of the control terminal of the electronic control unit 16, and the electronic control unit 16 obtains the working voltage. After the ignition switch 182 is turned on, the electronic control unit 16 is in an allowed starting state, and after the starting switch 183 is turned on, the electronic control unit 16 can control the auxiliary relay 185 to work, and then control the starting relay 184 to work, so that the electronic control unit 16 controls the starting of the starting 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 work of the electronic control unit 16. The detection controller 14 converts the output voltage of the power supply 12 to the preset power supply voltage, which 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 (for example, 12V) of the electronic control unit 16. 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 better power supply voltage to work normally, thereby normally controlling the starting motor 40 and ensuring the stability of the starting of the fuel motorcycle 100.
[0077] Please refer to Figure 4 The flowchart of the starting method of the fuel motorcycle provided by an embodiment of the present application is shown. Exemplarily, Figure 4 The starting method of the fuel motorcycle shown can be performed by the fuel motorcycle 100 of the above-mentioned embodiments, and includes the following steps.
[0078] Step S411, when the ignition switch is turned off, the fuel motorcycle is in a static state.
[0079] In some embodiments, when the ignition switch 181 is turned off, the fuel motorcycle 100 is in a static state.
[0080] Step S412, the detection controller detects whether the output voltage of the power supply is less than the preset voltage threshold.
[0081] In some embodiments, when the ignition switch 181 is off, i.e. the fuel motorcycle 100 is in a static 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 performed; 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 performed.
[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 off, i.e. the fuel motorcycle 100 is in a static 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 performed; 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 performed.
[0084] It can be understood that the execution order of steps S412 and S413 can be exchanged, or they can be executed simultaneously, which is not limited in the present application.
[0085] Step S414, the detection controller disconnects the preset power supply of the power supply to the electronic control unit.
[0086] In some embodiments, the detection controller 14 disconnects the preset power supply of the power supply 12 to the electronic control unit 16 to protect the power supply 12. Specifically, the detection controller 14 disconnects the path between the external output, i.e. the output positive OUT+ and the output negative OUT-, and the controlled positive U+ and the controlled negative 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, to turn off the output of the power supply 12 and protect the power supply 12. In some embodiments, the preset power supply of 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 timer and other basic functional components, i.e. to the functional components with low power consumption in the electronic control unit 16.
[0087] Step S415, the detection controller maintains the preset power supply of the power supply to the electronic control unit.
[0088] In some embodiments, the detection controller 14 maintains the preset power supply of the power supply 12 to the electronic control unit 16, and 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- of the detection controller 14 and the controlled positive pole U+ and the controlled negative pole U- of the electronic control unit 16, respectively, to maintain the power supply to the basic functional components (such as a timer, etc.) in the electronic control unit 16, and to maintain the normal operation of the basic functional components. Since the power consumption of the specific functional components (such as the control functional components of the starting motor 40) in the electronic control unit 16 is large, and the power consumption of the basic functional components (such as the timer, etc.) is small, that is, at this time, the detection controller 14 only needs to maintain a small current output, and the power supply 12 can be protected.
[0089] In 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 performed, when the ignition switch 181 is turned on, the fuel motorcycle 100 can be in a starting state, 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 paths 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 paths 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, respectively, so that the electronic control unit 16 can obtain a 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 the basic functional components of the electronic control unit 16 can all operate normally. 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 operating voltage (for example, 12V) of the electronic control unit 16. 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 for normal operation.
[0091] In 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 performed. When the ignition switch 181 is turned on, the fuel motorcycle 100 can be in a state of allowing starting. The detection controller 14 outputs the output voltage of the power supply 12 to the electronic control unit 16 through the paths of 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 paths 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, 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 voltage for operation, and the specific functional components and the basic functional components of the electronic control unit 16 can all operate 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 for normal operation.
[0093] Step S418: When the ignition switch and the starting switch are turned on, the electronic control unit controls the auxiliary relay and the starting relay to be turned on, and controls the starting of the starting motor, thereby controlling the starting of the fuel motorcycle.
[0094] In some embodiments, after step S416 or S417, step S418 is performed. When the ignition switch 182 is turned on, the electronic control unit 16 is in a state of allowing starting. When the starting switch 183 is turned on, the first end and the second end of the auxiliary relay 185 have current input so that the auxiliary relay 185 is turned on. The third end of the auxiliary relay 185 obtains current input from the output positive pole OUT+ of the detection controller 14 through the ignition switch 181 and the second fuse unit 142, and outputs current through the fourth end. The second end of the starting relay 184 obtains current input through the fourth end of the auxiliary relay 185, the starting relay 184 is turned on, the third end of the starting relay 184 obtains current input through the positive pole B+ of the power supply 12, and outputs current through the fourth end to the starting motor 40, thereby starting the engine 30 through the starting motor 40, so that the fuel motorcycle 100 is started.
[0095] In 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 starting motor 40 and ensuring the stability of the starting of the fuel motorcycle 100.
[0096] Please refer to Figure 5 The flowchart of the starting method of the fuel motorcycle provided by another embodiment of the application is shown. Exemplarily, Figure 5 The starting method of the fuel motorcycle shown can be performed by the fuel motorcycle 100 of the above-mentioned embodiments, and in the starting process of the fuel motorcycle 100, Figure 4 After step S418 of the starting method of the fuel motorcycle shown, the starting method of the fuel motorcycle can further include the following steps.
[0097] S419, the detection controller detects whether the output voltage of the power supply is less than the preset voltage threshold.
[0098] In some embodiments, at the moment when the starting motor 40 receives the current and works, the output voltage of the power supply 12 can sharply decrease, 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 can affect the normal work of the electronic control unit 16 (for example, too low voltage can trigger the automatic reset of the electronic control unit 16), at which time step S420 is performed; 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 performed.
[0099] Step S420, the detection controller converts the output voltage of the power supply to the 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 supply voltage, and outputs the preset supply voltage to the electronic control unit 16 through the path of the output positive terminal OUT+ of the detection controller 14, the conducting ignition switch 181 and the controlled terminal U0 of the electronic control unit 16, and the paths between the output positive terminal OUT+ and the output negative terminal OUT- of the detection controller 14 and the controlled positive terminal U+ and the controlled negative terminal U- of the electronic control unit 16, respectively, so that the electronic control unit 16 can obtain a normal working voltage, thereby avoiding the abnormal working condition of the electronic control unit 16 due to insufficient supply voltage (for example, too low voltage can trigger the automatic reset of the electronic control unit 16). It can be understood that the preset supply voltage is greater than the output voltage of the power supply 12, and the preset supply voltage can be the normal working voltage (for example, 12V) of the electronic control unit 16. When the output voltage of the power supply 12 is low (for example, less than 10.5V), the detection controller 14 outputs the preset supply voltage to the electronic control unit 16, which can ensure that the electronic control unit 16 can obtain a better supply voltage to work normally.
[0101] In 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 converts the output voltage of the power supply 12 to a preset supply voltage, and outputs the preset supply voltage to the electronic control unit 16 through the path of the output positive terminal OUT+ of the detection controller 14, the conducting ignition switch 181 and the controlled terminal U0 of the electronic control unit 16, and the paths between the output positive terminal OUT+ and the output negative terminal OUT- of the detection controller 14 and the controlled positive terminal U+ and the controlled negative terminal U- of the electronic control unit 16, respectively, so that the electronic control unit 16 can obtain a normal working voltage, thereby avoiding the abnormal working condition of the electronic control unit 16 due to insufficient supply voltage (for example, too low voltage can trigger the automatic reset of the electronic control unit 16). It can be understood that the preset supply voltage is greater than the output voltage of the power supply 12, and the preset supply voltage can be the normal working voltage (for example, 12V) of the electronic control unit 16. When the output voltage of the power supply 12 is low (for example, less than 10.5V), the detection controller 14 outputs the preset supply voltage to the electronic control unit 16, which can ensure that the electronic control unit 16 can obtain a better supply voltage to work normally.
[0103] At the moment when the starting motor 40 receives the current and works, the output voltage of the power supply 12 can be sharply decreased. 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, 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. 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. Thus, the electronic control unit 16 can obtain a better power supply voltage and avoid abnormal working conditions.

The starting method of the fuel motorcycle is exemplarily shown in Figure 6 The starting method of the fuel motorcycle is substantially the same as that shown in Figure 4 The starting method of the fuel motorcycle is substantially the same as that shown in Figure 4 The order of the steps S412 and S413 shown in the starting method of the fuel motorcycle is exchanged, and other steps remain the same. Figure 6 The starting method of the fuel motorcycle can further include the following steps.
[0105] In 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 performed. 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 performed.
[0107] In 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 performed. 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 performed.
[0109] Figure 6The steps S611 and S614 to S618 shown can correspond to Figure 4 The steps S411 and S414 to S418 shown will not be repeated here.
