Electrically-assisted bicycle comprises control unit that detects inclination of bicycle transversely to direction of travel and inclination of bicycle in direction of travel of electric motor

摘要

#CMT# #/CMT# The bicycle (100) has an electric motor (10) and a sensor (14) such as two-axis acceleration sensor that is attached to bicycle for detecting an inclination (16) of bicycle transversely to direction of travel (18). A control unit (12) is provided to record detected data of sensor as a function of data of inclination, such that the drive power of electric motor is changed in dependence on speed of bicycle. The control unit detects inclination of bicycle transversely to direction of travel and inclination of bicycle in the direction of travel of electric motor. #CMT# : #/CMT# An independent claim is included for a method for adjusting power for operation of bicycle having electric motor. #CMT#USE : #/CMT# Electrically-assisted bicycle. #CMT#ADVANTAGE : #/CMT# The bicycle is energy efficient while adapting to driving route. By detecting inclination in curves and slopes on driving route, the speed of electric motor is maintained, while ensuring secure and user-friendly cycling. Due to reduction of speed in downhill rides, the energy of cycling can be saved. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawings show the schematic view of bicycle, and explanatory view illustrating the inclination of bicycle transverse to direction of travel. 10 : Electric motor 12 : Control unit 14 : Sensor 16 : Inclination of bicycle 18 : Direction of travel 100 : Bicycle.
