Electric-powered bicycle operable in an automatic driving mode and a boosting driving mode
First Claim
1. An electric-powered bicycle, comprising:
- a pedaling device operable in a manual driving mode so as to drive the bicycle to move forward;
an electric power source;
an electric driving motor operable in an automatic driving mode and in a boosting driving mode to drive the bicycle to move forward;
a motor driver, interconnecting said electric power source and said electric driving motor, for controlling activation of said electric driving motor when said electric power source is activated;
a speed control unit including a twist grip throttle which is operable to move between non-operative and operative positions;
a throttle detector associated operably with said twist grip throttle so as to generate a throttle twist signal when said twist grip throttle is moved to the operative position;
a bicycle torque detector associated operably with said pedaling device so as to generate a bicycle torque signal corresponding to bicycle torque on said pedaling device;
a bicycle speed detector for generating a bicycle speed signal corresponding to forward moving speed of the bicycle; and
a monitoring unit connected to said throttle detector, said bicycle torque detector and said bicycle speed detector so as to monitor the position of said twist grip throttle, the bicycle torque on said pedaling device, and the forward moving speed of the bicycle, said monitoring unit being further connected to said motor driver;
said monitoring unit controlling said motor driver to deactivate said electric driving motor when said twist grip throttle is in the non-operative position and the bicycle torque on said pedaling device is not over a preset limit while said electric power source is activated, and when said twist grip throttle is in the operative position, the bicycle torque on said pedaling device is not over the preset limit, and the forward moving speed of the bicycle is not over a preset safety speed while said electric power source is activated.

Abstract
An electric-powered bicycle has a monitoring unit connected to a throttle detector, a bicycle torque detector and a bicycle speed detector so as to monitor the position of a twist grip throttle, the bicycle torque on a pedaling device, and the forward moving speed of the bicycle. The monitoring unit is further connected to a motor driver, and controls the motor driver to deactivate an electric driving motor when the twist grip throttle is in the non-operative position and the bicycle torque on the pedaling device is not over a preset limit while an electric power source for the electric driving motor is activated, and when the twist grip throttle is in the operative position, the bicycle torque is not over the present limit and the forward moving speed of the bicycle is not over a preset safety speed while the electric power source is activated, thereby resulting in enhanced user safety.
