Problems solved by technology

This kind of car has a certain energy saving effect when riding uphill, but in general, the energy saving is not significant
Because when an electric vehicle is driving on a flat road, people do not need a large additional boost, but the DC motor still outputs a corresponding boost to the manpower, which not only wastes the energy of the battery, but also may cause an unsafe state of overspeeding.

Abstract

A foot-controlled intelligent electric aided bicycle used for electric-and-manpower double driving has a digital control system and includes a storage battery, a digital sensor, a controller, a DC motor, a pedal spindle device and a pedal digital speed sensing asynchronous speed control electronic switch access circuit, wherein the controller consists of a digital dynamic moment signal processingcircuit, a digital logic interface, a power amplification circuit and a reference operation speed digital pulse signal generator; the pedal digital speed sensing asynchronous speed control electronicswitch access circuit consists of an asynchronous speed setting circuit, a pedal digital speed sensor, a digital processing and logical interface circuit, an overdrive suppressing circuit and an ultralow speed protection circuit. The electric aided bicycle has the advantages of foot control, intelligence, convenient use, low cost, long journey of one-charge and saving energy consumption.

Description

technical field [0001] The invention relates to an electric bicycle, in particular to a foot-controlled intelligent electric power-assisted bicycle which is dual-driven by electricity and manpower. Background technique [0002] Electric bicycles, a clean and environmentally friendly means of transportation, have been adopted by more and more people. An electric bicycle can be considered to be composed of a DC motor drive mechanism on the basis of a bicycle. The basic principle is: a bicycle driven by a DC motor powered by a battery. Its electronic control system mainly includes batteries, controllers and DC motors. The operation process is as follows: the storage battery supplies power to the DC motor through the controller, the DC motor is placed in the rear wheel, and the rotation of the DC motor drives the bicycle to move forward. The controller of the electric bicycle is connected to a speed control handle, and a power sensor is installed on the pedal center shaft. Tur...
