Electric vehicle and method for controlling electric vehicle
An electric vehicle includes a carrier, a free-wheel unit, a foot-wheel unit, a driving unit, a first angle-detecting unit and a micro processing unit. The carrier is for supporting a user. The free-wheel unit is disposed at one end of the carrier. The foot-wheel unit is disposed at the other end of the carrier. The driving unit is disposed at the free-wheel unit or the foot-wheel unit, and is for providing a power to the electric vehicle. The first angle-detecting unit is disposed at the free-wheel unit or the carrier, and is for detecting a swinging status between the free-wheel unit and the carrier so as to provide a swinging signal. The micro processing unit is signally connected to the driving unit and the first angle-detecting unit. When the swinging signal achieves a predetermined condition determined by the micro processing unit, the driving unit is turned on.
1. An electric vehicle, comprising:
a carrier for supporting a user;
a free-wheel unit disposed at one end of the carrier;
a foot-wheel unit disposed at the other end of the carrier;
a driving unit disposed at one of the free-wheel unit and the foot-wheel unit, and for providing a power to the electric vehicle;
a first angle-detecting unit disposed at one of the free-wheel unit and the carrier, the first angle-detecting unit for detecting a swinging status between the free-wheel unit and the carrier so as to provide a swinging signal;
a micro processing unit signally connected to the driving unit and the first angle-detecting unit; and
a voice prompting unit disposed at the carrier and electrically connected to the micro processing unit;
wherein when the swinging signal achieves a predetermined condition which is determined by the micro processing unit, the driving unit is turned on.
2. The electric vehicle of claim 1 , wherein the micro processing unit comprises a Bluetooth receiver for receiving a Bluetooth signal so as to lock the driving unit.
3. The electric vehicle of claim 1 , further comprising:
a liquid-crystal display unit disposed on the carrier and electrically connected to the micro processing unit.
4. The electric vehicle of claim 1 , further comprising:
a light display unit disposed on the carrier and electrically connected to the micro processing unit.
5. The electric vehicle of claim 1 , further comprising:
a second angle-detecting unit disposed at the foot-wheel unit and for detecting a swinging status between the foot-wheel unit and the carrier so as to provide a turning signal, and the micro processing unit is for determining whether the electric vehicle turns or goes straight according to the turning signal.
6. The electric vehicle of claim 1 , further comprising:
a load detecting unit disposed on the carrier and for detecting a load of the carrier.
7. A method for controlling an electric vehicle, the electric vehicle comprising a carrier, a free-wheel unit, a foot-wheel unit, a driving unit, a first angle-detecting unit and a micro processing unit, wherein the free-wheel unit and the foot-wheel unit are disposed at two ends opposite to each other of the carrier, respectively, the driving unit is disposed at one of the free-wheel unit and the foot-wheel unit and is for providing a power to the electric vehicle, the first angle-detecting unit is disposed at the free-wheel unit and is signally connected to the micro processing unit, and the method for controlling the electric vehicle comprising:
standing on the carrier; and
operating a power starting procedure, wherein when the electric vehicle goes straight, the free-wheel unit is swung so as to cause the first angle-detecting unit to send a swinging signal to the micro processing unit for turning on the driving unit.
8. The method for controlling the electric vehicle of claim 7 , wherein in the power starting procedure, a second angle-detecting unit of the electric vehicle detects a swinging status between the foot-wheel unit and the carrier to provide a turning signal, and the micro processing unit determines whether the electric vehicle goes straight according to the turning signal.
9. The method for controlling the electric vehicle of claim 7 , wherein a load is detected by a load detecting unit of the electric vehicle so as to send a loading signal while standing on the carrier.
10. The method for controlling the electric vehicle of claim 7 , further comprising:
operating a speed switching procedure, wherein the free-wheel unit is swung again to enhance the a power to the electric vehicle provided by the driving unit.
11. The method for controlling the electric vehicle of claim 7 , further comprising:
operating a power accumulating procedure, wherein the free-wheel unit is swung again to accumulate a starting time of the driving unit.
12. A method for controlling an electric vehicle, the electric vehicle comprising a carrier, a free-wheel unit, a foot-wheel unit, a driving unit, a first angle-detecting unit and a micro processing unit, wherein the free-wheel unit and the foot-wheel unit are disposed at two ends opposite to each other of the carrier, respectively, the driving unit is disposed at one of the free-wheel unit and the foot-wheel unit and is for providing a power to the electric vehicle, the first angle-detecting unit is disposed at the free-wheel unit and is signally connected to the micro processing unit, and the method for controlling the electric vehicle comprises:
standing on the carrier; and
swinging the free-wheel unit to cause the first angle-detecting unit to send a swinging signal to the micro processing unit for controlling a starting, a power magnitude switching or a power lasting time of the driving unit.
