Problems solved by technology

[0005] In the above-mentioned electric bicycle, since the self-propelled power is determined only according to the operation amount of the rider's self-propelled operation, for example, if the operation amount and the self-propelled power are adapted to a flat road surface, the output is insufficient when going uphill, and the output is insufficient when going downhill. Desired running performance cannot be obtained due to excess output
In addition to road conditions, for example, when the total weight of the rider's weight and the weight of the cargo is greater than the reference value, the output becomes insufficient, and if it is smaller than the reference value, the output becomes excessive.

Embodiment Construction

[0027] Hereinafter, the present invention will be described in detail with reference to the drawings. figure 1 It is a figure showing the structure of the electric bicycle to which this invention was applied, and the illustration of the structure unnecessary for description of this invention is abbreviate|omitted.

[0028] On the handlebar 10, like conventional bicycles, the left end is provided with the brake lever 11 for the rear wheel, and the right end is provided with the brake lever 13 for the front wheel. Near the fulcrum of each brake lever 11,13 , brake switches 12, 14 that detect that each brake lever 11, 13 is in an operating state and output a signal SB that is in braking are provided. Furthermore, on the right end of the handlebar 10, a throttle lever 16 as a self-propelled operation input unit indicating the self-propelled power generated in the drive motor M described later and a joint for detecting the operation angle θth as an operation amount are provided. F...

Abstract

A motor-driven bicycle includes an acceleration detecting portion 203 for detecting an acceleration, and a rapid acceleration suppressing control portion 205 for controlling the self-running motive power on the basis of the detected acceleration. In addition, a pushcart walking control portion 211 is provided to respond the self-running operation inputted from a self-running operation inputting portion (a throttle lever), so that a drive motor M generates the self-running motive power in response to the walking speed. The pushcart walking control portion 211 judges self-operations generated by the throttle lever are in non-riding state, while the drive motor M generates the self-running motive power in response to the walking speed.

Description

technical field [0001] 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 [0002] 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 an electric assist bicycle, Unlike so-called power-assist bicycles, electric bicycles are equipped with a drive motor that generates self-propelling power in r...
