[0041] Figure 3 The vehicle speed management method according to the embodiment of the present invention is shown. The vehicle speed management method according to the embodiment of the present invention can be applied to an electric vehicle, such as an electric motorcycle.

[0042] First, as in step S310, a location of a corresponding electronic device is obtained. It is noted that, in some embodiments, the electronic device may be a mobile device. In some embodiments, the electronic device may be an electric vehicle. The electronic device may have a positioning unit to obtain the current location of the corresponding electronic device. Then, as in step S320, a speed limit of a corresponding route is obtained according to the location. Figure 4 The method for obtaining the speed limit according to an embodiment of the present invention is shown. In step S410, a database in an electronic device such as a mobile device or an electric vehicle is searched according to the location to obtain the speed limit of the corresponding route. It is noted that in some embodiments, the mobile device can be connected to the electric vehicle via a wireless network, and the mobile device transmits the speed limit to the electric vehicle via the wireless network. Figure 5 A method for obtaining a speed limit according to another embodiment of the present invention is displayed. In step S510, an electronic device, such as a mobile device or an electric vehicle, transmits a location to a remote server via a network. Then, in step S520, a database is retrieved based on the location by the remote server to obtain the speed limit of the corresponding route, and in step S530, the speed limit is transmitted to the electronic device via the network by the remote server. It is worth noting that in some embodiments, the speed limit can be displayed by a display unit of the electric vehicle to remind the user.

[0043] Next, as in step S330, a vehicle speed of the corresponding electric vehicle is detected, and as in step S340, it is determined whether the vehicle speed is greater than or equal to the speed limit. It is reminded that in some embodiments, the electric vehicle can directly obtain the vehicle speed. In some embodiments, the mobile device can detect its moving speed and set its moving speed as the vehicle speed of the corresponding electric vehicle. When the vehicle speed is not greater than or equal to the speed limit (No in step S350), the process returns to step S310. When the vehicle speed is greater than or equal to the speed limit (Yes in step S350), as in step S360, it is determined whether an acceleration instruction of the corresponding electric vehicle is received. It is reminded that in some embodiments, the user can generate an acceleration instruction through the acceleration controller of the electric vehicle, such as the refueling handle of the faucet, or the refueling pedal. When the acceleration instruction of the corresponding electric vehicle is not received (No in step S370), the process returns to step S310. When the acceleration instruction of the corresponding electric vehicle is received (Yes in step S370), as in step S380, the acceleration instruction of the corresponding electric vehicle is ignored or canceled. It is worth noting that, in some embodiments, when the vehicle speed is greater than or equal to the speed limit and an acceleration command of the corresponding electric vehicle is received, the motor unit of the electric vehicle may be caused to suspend outputting power.

[0044] Figure 6A vehicle speed management method according to another embodiment of the present invention is shown. The vehicle speed management method according to the embodiment of the present invention can be applied to an electric vehicle, such as an electric motorcycle.

[0045] First, as in step S602, the electric vehicle receives an activation instruction corresponding to a speed limit function. It is worth noting that in some embodiments, the activation instruction can be received by a button of the electric vehicle or by a mobile device. Then, as in step S604, a position of a corresponding electronic device is obtained. Similarly, in some embodiments, the electronic device can be a mobile device. In some embodiments, the electronic device can be an electric vehicle. The electronic device can have a positioning unit to obtain the current position of the corresponding electronic device. Then, as in step S606, a speed limit of a corresponding route is obtained based on the position. It is worth noting that in some embodiments, a database in an electronic device, such as an electric vehicle or a mobile device, can be retrieved based on the position to obtain the speed limit of the corresponding route. It is reminded that in some embodiments, the mobile device can be connected to the electric vehicle via a wireless network, and the mobile device transmits the speed limit to the electric vehicle via the wireless network. In some embodiments, an electronic device, such as an electric vehicle or a mobile device, can be used to transmit the position to a remote server via a network. A remote server is used to retrieve a database according to the location to obtain the speed limit of the corresponding route, and the remote server is used to transmit the speed limit to the electronic device through the network. Similarly, in some embodiments, the speed limit can be displayed by a display unit of the electric vehicle to remind the user. Then, as in step S608, a vehicle speed of the corresponding electric vehicle is detected, and as in step S610, it is determined whether the vehicle speed is greater than or equal to the speed limit. It is reminded that in some embodiments, the electric vehicle can directly obtain the vehicle speed. In some embodiments, the mobile device can detect its moving speed and set its moving speed to the vehicle speed of the corresponding electric vehicle. When the vehicle speed is not greater than or equal to the speed limit (no in step S612), the process returns to step S604. When the vehicle speed is greater than or equal to the speed limit (yes in step S612), as in step S614, the motor unit is caused to enter a power generation mode to charge a battery of the electric vehicle and generate a reverse torque to assist the electric vehicle in deceleration. Afterwards, as in step S616, it is determined whether an acceleration command of the corresponding electric vehicle is received. Similarly, in some embodiments, the user can generate an acceleration command through the acceleration controller of the electric vehicle, such as the refueling handle of the faucet, or the refueling pedal. When the acceleration command of the corresponding electric vehicle is not received (No in step S618), the process returns to step S604. When the acceleration command of the corresponding electric vehicle is received (Yes in step S618), as in step S620, the acceleration command of the corresponding electric vehicle is ignored or canceled. Similarly, in some embodiments, when the vehicle speed is greater than or equal to the speed limit and the acceleration command of the corresponding electric vehicle is received, the motor unit of the electric vehicle can be caused to suspend the output of power.

[0046] Therefore, by means of the vehicle speed management method and the electric vehicle thereof of this case, the speed of the electric vehicle can be automatically managed according to the position and speed of the vehicle, thereby controlling the speed of the vehicle not to exceed the speed limit of the road section, and timely starting the mechanism to use the motor to assist the electric vehicle in decelerating and charging the battery.

The program code may be contained in a physical medium, such as a floppy disk, an optical disk, a hard disk, or any other machine-readable (such as computer-readable) storage medium, or a computer program product in an external form, wherein when the program code is loaded and executed by a machine, such as a computer, the machine becomes an apparatus for participating in the present invention. The program code may also be transmitted by some transmission medium, such as wires or cables, optical fibers, or any transmission mode, wherein when the program code is received, loaded and executed by a machine, such as a computer, the machine becomes an apparatus for participating in the present invention. When implemented on a general-purpose processing unit, the program code combines with the processing unit to provide a unique device that operates similarly to application-specific logic circuits.
