Abstract
The present disclosure relates to a boosting mode of an electric bicycle, and has the effect of enabling safe operation of the electric bicycle while providing a necessary acceleration force by preventing a sudden acceleration not intended by a user by double determining the user's intention when rapid acceleration is required, such as when starting or overtaking an electric bicycle.
Claims8
An apparatus for driving an electric bicycle, comprising:
- a pedal sensor for measuring a position or speed of a pedal;
- a wheel sensor for measuring a position or speed of a driving wheel;
- and
- a driving controller for controlling a speed of a motor for driving the driving wheel according to a position difference or speed difference between the pedal and the driving wheel;
- wherein the driving controller increases a control current of the motor in a boosting mode set by a user's boosting control for a certain period of time compared to a previous driving,
- wherein the driving controller generates a first additional control current corresponding to a first percentage (%) when the electric bicycle enters the boosting mode at a first speed and generates a second additional control current corresponding to a second percentage (%), which is higher than the first percentage (%), when the electric bicycle enters the boosting mode at a second speed, which is higher than the first speed,
- wherein the first percentage (%) and the second percentage (%) are defined relative to the control current of the motor used immediately before the electric bicycle enters the boosting mode.
A method for driving an electric bicycle performed by a driving controller of the electric bicycle comprising one or more processors and memories, the method comprising:
- measuring a position or speed of a pedal;
- measuring a position or speed of a driving wheel;
- determining a speed of a motor for driving the driving wheel based on a position difference or a speed difference between the pedal and the driving wheel;
- generating a motor current for controlling the motor at the determined speed;
- determining whether it is a boosting mode for acceleration;
- and
- generating an additional current of the motor for acceleration in response to the determination result being a boosting mode,
- wherein the generating of the additional current of the motor for acceleration comprises:
- generating a first additional control current corresponding to a first percentage (%) when the electric bicycle enters the boosting mode at a first speed and generating a second additional control current corresponding to a second percentage (%), which is higher than the first percentage (%), when the electric bicycle enters the boosting mode at a second speed, which is higher than the first speed,
- wherein the first percentage (%) and the second percentage (%) are defined relative to the control current of the motor used immediately before the electric bicycle enters the boosting mode.
