Abstract:
A direction control method for the self-balancing electric vehicle and electric vehicle using the same are disclosed in the present invention. The direction control method for the self-balancing electric vehicle includes the following steps: disposing a plurality of direction control units under the foot treadles of the self-balancing electric vehicle, wherein each direction control unit comprises a first conductive plate, a second conductive plate and a flexible material, wherein the aforementioned flexible material is disposed between the first conductive plate and the second conductive plate; respectively measuring the capacitance values between the first conductive plates and the second conductive plates of the plurality of direction control units; and determining the tilt direction of the center of gravity of a riding object based on the capacitance values of the direction control units and the positions of the direction control units, such that the moving direction of the self-balancing electric vehicle can be determined.
Abstract:
A Bluetooth data/control message transmission module, an interaction device and a method thereof are provided in the present invention. The Bluetooth data/control message transmission module connects to a mobile device with Bluetooth. The Bluetooth data/control message transmission module includes a process unit, a modulation module and a Bluetooth module. The process unit is for providing a digital data. The modulation module receives the digital data and modulates the digital data with a analog carrier signal to generate a modulation signal whose frequency is lower than 8 KHz. The Bluetooth module uses a headset profile to link with the mobile device, wherein the mobile device serves the Bluetooth module as a headset. The Bluetooth module samples the modulation signal, to serve the sampled modulation signal as a voice signal to send to the mobile device through the Bluetooth protocol.
