It can be seen from the above implementations that the present invention has the following advantages: First, the use of the universal serial bus signal in the server key and the controller area network signal to convert between each other, not only can reduce the hardware complexity and size of the console , It can also improve the expandability of the controller area network and realize the non-disassembly detection. Second, when the console is damaged, the system can still provide power to the electrical components through the server key and continue testing. The repairer does not need to replace the console and disconnect cables for testing, which is very convenient. Third, for the electrical components that need to be updated, real-time version updates can be provided through the server key and the controller local area network. There is no need to worry about the problem that electrical components will fail due to unupdated links.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Anyone who is familiar with the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection of the present invention The scope shall be subject to the definition of the attached patent application scope.

An electric bicycle control system for connecting a controller area network of an electric bicycle and a control terminal and controlling a plurality of electric components. The electric component signals are connected to the controller area network. The electric bicycle control system includes : A server key module, including: a first connection port connected to the control terminal, the control terminal transmitting a universal serial bus signal; a server key, one end of which is coupled to the first connection port, the server The key converts the universal serial bus signal into a controller area network signal, the server key includes: a universal serial bus processing unit connected to the first port, the universal serial bus processing unit converges the universal serial The row signal is converted into a payload signal; a server key processor is connected to the universal serial bus processing unit, and the server key processor converts the payload signal into a controller area network pre-signal; a controller area The network processing unit is connected to the server key processor, and the controller area network processing unit converts the controller area network pre-signal into the controller area network signal; A power control unit connected to the server key processor and outputting a power control signal; and a power monitoring unit connected to the server key processor and receiving a voltage signal of each of the electric components; and a second connection port, Coupled to the other end of the server key; and a console, including: a console port, the console port is detachably connected to the second port and coupled to the controller area network; a power switch The controller is coupled to the power control unit via the second connection port and the console port, the power switch controller turns on or off each of the electric components according to the power control signal; and a console power supply unit, through the first Two ports and the console port are coupled to the power monitoring unit, and the console power unit receives the voltage signal of each of the electrical components; wherein, the controller area network signal passes through the second port and the console The port is transmitted to the local area network of the controller. For the electric bicycle control system described in item 1 of the scope of patent application, the first port is a universal serial bus port, and the second port is an A-type universal serial bus port or a C Type universal serial bus port, the console port corresponds to the second port. For example, the electric bicycle control system described in item 2 of the scope of patent application, wherein, when the second port is the A-type universal serial bus port, the second port has nine pins, two of which are Pin is coupled to the controller area network; and when the second port is the C-type universal serial bus port, the second port has twenty-four pins, two of which are coupled to the control Local area network. A control method of an electric bicycle is used to allow a control terminal to control a plurality of electric components of an electric bicycle. The control method of the electric bicycle includes the following steps: a signal conversion step is to drive a servo key module from the control terminal A universal serial bus signal is converted into a controller area network signal, the universal serial bus signal is transmitted to a server key through a first port of the server key module, and the server key is the universal serial The bus signal is converted into the controller area network signal; a signal transmission control step is to drive a console to pass the controller area network signal through a second port of the server key module and the control One of the console ports of the station is transmitted to a controller area network, whereby the control signal is connected to the electrical components of the controller area network; a power switch step is to drive a power control unit of the server key to output a Power control signal, and then drive the console power switch controller to turn on or off each of the electric components according to the power control signal; and a power monitoring step, which drives a power monitoring unit of the server key and a control of the console The power supply unit receives the voltage signal of each electric component, so that the control terminal monitors the electric components. For example, the control method of electric bicycle described in item 4 of the scope of patent application, wherein the first connection port is a universal serial bus connection port, and the second connection port is an A type universal serial bus connection port or a C type Universal serial bus port, the console port corresponds to the second port. For example, the control method of electric bicycle described in item 5 of the scope of patent application, wherein, when the second connection port is the A-type universal serial bus connection port, the second connection port has nine pins, two of which are The pin is coupled to the controller local area network; and When the second connection port is the C-type universal serial bus connection port, the second connection port has twenty-four pins, and two of the pins are coupled to the controller area network. For example, the control method of the electric bicycle described in item 4 of the scope of patent application further includes: a component confirmation step, through the server key module, the control panel, and the controller area network to make the control terminal confirm each of the Whether the electrical component exists; and a version update step is to make the control terminal send update information corresponding to one of the electrical components, and convert the update information into the universal serial bus signal and send it to the server key module Then, the server key module outputs the controller area network signal corresponding to the update information to the control panel, and transmits it to the electric component via the controller area network.
