[0022] 3 is a flowchart of an embodiment of a vehicle movement assistance method of the present invention. The vehicle movement assistance method of the present invention is applied to an electric vehicle, for example, an electric motorcycle.

[0023] First, in step S310, a first sensor is used to detect a movement corresponding to the electronic device. It is noteworthy that in some embodiments, the electronic device is a mobile device, such as a smartphone or a wireless key of the electric vehicle, and the first sensor is used to detect the movement of the mobile device. In some embodiments, the electronic device is installed in the electric vehicle, and the first sensor is used to detect the movement of the electric vehicle. Then, in step S320, the electric vehicle obtains the movement of the electronic device. As described above, when the electronic device is a mobile device, the mobile device can be connected to the electric vehicle via a network and transmit the movement detected by the first sensor to the electric vehicle. Then, in step S330, the electric vehicle determines an auxiliary power according to the movement, and the auxiliary power is provided to the motor unit to assist the movement of the electric vehicle, as shown in step S340. It is noteworthy that in some embodiments, when the speed of movement is fast, the auxiliary power determined by the electric vehicle is lower than the auxiliary power determined when the speed of movement is slow.

[0024] 4 is a flow chart of another embodiment of the vehicle movement assistance method of the present invention. The vehicle movement assistance method of the present invention is used in an electric vehicle, such as an electric motorcycle. In this embodiment, in addition to detecting the movement of the electronic device, the electric vehicle can further be managed according to the gradient of the road where the electric vehicle is located.

[0025] First, in step S410, the electric vehicle receives an activation instruction corresponding to a mobility assistance function. It is to be noted that in some embodiments, the activation instruction is received by a button on the electric vehicle or from a mobile device. Then, in step S420, a second sensor on the electric vehicle is used to detect the inclination of the electric vehicle on the road relative to gravity, and the road gradient is determined based on the inclination. In step S430, it is determined whether the road gradient is greater than a predetermined degree, for example, 10 degrees. It is to be noted that the above-mentioned predetermined degrees are merely examples of the present invention, and the present invention is not limited thereto. The predetermined degree is designed according to different demands and applications. When the road gradient is not greater than the predetermined degree (step S430, no), in step S470, the electric vehicle ignores or cancels the activation instruction. When the road gradient is greater than the predetermined degree (step S430, yes), in step S440, it is determined whether the road is uphill or downhill based on the road gradient and the traveling direction of the electric vehicle. When the road is downhill (downhill in step S450), the electric vehicle ignores or cancels the start-up instruction in step S470. When the road is uphill (uphill in step S450), the electric vehicle determines the auxiliary power according to the movement of the electronic device in step S460, and provides the auxiliary power to the motor unit to assist the movement of the electric vehicle.

[0026] 5 is a flow chart of another embodiment of the vehicle movement assistance method of the present invention. The vehicle movement assistance method of the present invention is used for an electric vehicle, for example, an electric motorcycle. In this embodiment, in addition to detecting the movement of the electronic device, the electric vehicle can be further managed according to whether the road on which the electric vehicle is located is uphill or downhill.

[0027] First, in step S510, the electric vehicle receives an activation instruction corresponding to the mobility assistance function. Similarly, in some embodiments, the activation instruction is received by a button on the electric vehicle or from a mobile device. Then, in step S520, a second sensor on the electric vehicle is used to detect the inclination of the electric vehicle on the road relative to gravity, and the road gradient is determined based on the inclination. In step S530, it is determined whether the road gradient is greater than a predetermined degree. When the road gradient is not greater than the predetermined degree (step S530, no), in step S540, the electric vehicle ignores or cancels the activation instruction. When the road gradient is greater than the predetermined degree (step S530, yes), in step S550, it is determined whether the road is uphill or downhill based on the road gradient and the traveling direction of the electric vehicle. When the road is uphill (step S560, uphill), in step S570, the electric vehicle determines the auxiliary power according to the movement of the electronic device and provides the auxiliary power to the motor unit to assist the movement of the electric vehicle. When the road is downhill (step S560, downhill), in step S580, the motor unit is put into a generating mode to charge the battery of the electric vehicle and generate a reverse torque to assist the deceleration of the electric vehicle.

[0028] Thus, the vehicle movement assistance method and its electric vehicle automatically provides auxiliary power to the electric vehicle to assist movement based on movement detected by a sensor, thereby providing an automatic and intelligent mechanism to drive the motor and assist movement of the vehicle.

[0029] The vehicle mobility assistance methods may take the form of program code (i.e., executable instructions) embodied in a tangible medium, such as a floppy disk, CD-ROM, hard drive, or any other machine-readable storage medium, which when loaded into a machine, such as a computer, and executed, causes the machine to thereby become an apparatus for performing the methods. The methods may also be embodied in the form of program code transmitted over some transmission medium, such as transmission over electrical wiring, cabling, or optical fiber, which when received, loaded into a machine, such as a computer, and executed, causes the machine to become an apparatus for performing the disclosed methods. When implemented on a general-purpose processor, the program code combines with the processor to provide a unique apparatus that operates analogously to application-specific logic circuits.

Those skilled in the art can still make various changes and modifications without departing from the scope and spirit of the present invention.
