WIPO Patent Application WO/2018/026180
Kind Code:
The present invention relates to a driving control method of an in-wheel drive for an electric bicycle, which is capable of automatically traveling at a constant speed when the in-wheel drive for the electric bicycle is driven, thereby minimizing driver fatigue caused by foot power, enabling a control operation to be performed more simply and effectively in various situations required while traveling, and furthermore greatly contributing to enhancing convenience functions such as user recognition, etc. That is, the present invention relates to a driving control method of a conventional electric bicycle using an auxiliary pedal system, comprising: a start-up step for entering a traveling ready state thereof in which electric traveling is possible immediately upon receipt of a start signal by supplying power to an electric motor (41) of an electric drive driving apparatus (40) and a driving control unit (80); a constant-speed traveling step in which traveling is possible at a constant rotational speed in accordance with the driving of the electric drive apparatus separately from the foot power of pedals; a constant-speed traveling release step for automatically releasing a constant-speed traveling state as needed while constant-speed traveling; and a hill-start assist step for preventing the electric bicycle from being pushed backward in advance when stopping or starting after stopping on a hill in which a large load and especially a counter electromotive force are applied to the electric drive apparatus and the electric motor (41).
