Abstract

The invention provides a motor-driven bicycle, including a drive motor for generating a self-running power in response to an operated amount of a self-running operation by a driver, capable of achieving a self-running function matched to a walking speed and obtaining an optimum acceleration irrespective of a road condition or a variation in load such as a deadweight. Solving Meansu A motor-driven bicycle, which includes a drive motor for generating a self-running power in response to an operated amount of a self-running operation by a driver, is provided with an acceleration detecting portion 203 for detecting an acceleration, and a rapid acceleration suppressing control portion 205 for controlling the self-running power on the basis of the detected acceleration. If the detected acceleration is more than a specific reference acceleration, the rapid acceleration suppressing control portion 205 gradually reduces the self-running power to be supplied to a drive motor M from a reference value determined in response to the amount of the self-running operation, and thereafter, if the acceleration is less than the reference acceleration, the control portion 205 gradually increases the self-running power to be supplied to the drive motor M up to the reference value determined in response to the amount of the self-running operation.

Description

[0001] The present invention is a divisional application of the No. 01110905.X patent application entitled "Electric Bicycle" submitted on February 28, 2001. technical field

[0002] The present invention relates to an electric bicycle equipped with a drive motor that generates self-propelled power according to the amount of self-propelled operation performed by the rider, and particularly relates to an electric bicycle that can obtain optimum acceleration regardless of changes in road surface conditions and loads, etc. At the same time, it is an electric bicycle that can obtain self-propelled power corresponding to the walking speed when the cyclist pushes the bicycle and walks. Background technique

[0003] For example, Japanese Patent Application Laid-Open No. 9-263289 proposes: an electric motor that generates auxiliary power in response to a pedaling force input to a crankshaft, synthesizes the auxiliary power and pedaling force and transmits it to the drive wheel, and a...
