Abstract
An electric bicycle includes: a sleeve to which power for driving the electric bicycle is input; a rear wheel; and a power transmission mechanism that transmits the power input to the sleeve to the rear wheel. The electric bicycle determines an abnormality of the power transmission mechanism or prevents or prohibits driving performed by using the power transmission mechanism based on a reference composite gear ratio of the power transmission mechanism acquired at a first time and current composite gear ratio of the power transmission mechanism acquired at a second time subsequent to the first time.
Claims16
A vehicle comprising:
- an input unit to which power for driving the vehicle is input;
- an output unit that outputs the power input to the input unit;
- and
- a power transmission mechanism that transmits the power input to the input unit to the output unit, wherein
- an abnormality of the power transmission mechanism is determined or driving performed by using the power transmission mechanism is prevented or prohibited based on
- first gear ratio-related information, which is information acquired at a first time and related to a gear ratio of a transmission section which is the entirety or a part of the power transmission mechanism, and
- second gear ratio-related information, which is information acquired at a second time subsequent to the first time and related to a gear ratio of the transmission section.
(canceled)
A method for monitoring an abnormality of a power transmission mechanism installed in a vehicle, the method comprising:
- a step of acquiring first gear ratio-related information, which is information related to a gear ratio of a transmission section which is the entirety or a part of the power transmission mechanism, at a first time;
- a step of acquiring second gear ratio-related information, which is information related to a gear ratio of the transmission section, at a second time subsequent to the first time;
- and
- a step of determining an abnormality of the power transmission mechanism or preventing or prohibiting driving performed by using the power transmission mechanism based on the first gear ratio-related information and the second gear ratio-related information.
