Power output control method of electric auxiliary bicycle

Abstract

The invention discloses a power output control method of an electric auxiliary bicycle. First, second and third auxiliary force control modes are set in an auxiliary force control system of the bicycle. When the first auxiliary force control mode is executed, a motor is controlled to generate a matched output power value according to the detected pedaling frequency revolution value and the slope value, and the ratio of the output power value to the pedaling frequency revolution value is kept to be a preset torque reference value. When the second auxiliary force control mode is executed, the detected pedaling force torque value is smaller than the preset first torque set value, and the motor is controlled to generate compensation torque according to the pedaling force torque value. When the third auxiliary force control mode is executed, a manpower input power value is calculated according to the detected pedaling force torsion value and the pedaling frequency revolution value, when the manpower input power value is smaller than a preset auxiliary power set value, the motor is controlled to generate compensation power, and the compensation power value and the manpower input power value are equal to the auxiliary power set value; A user can select a proper power output mode according to different environment states and riding requirements, and comfortable riding experience is achieved.

Description

technical field [0001] The present invention relates to a power output control method of an electric assisted bicycle, especially a power control method for an electric assisted bicycle that allows users to select an appropriate power output mode according to different environmental conditions and riding needs to achieve a better and more comfortable riding experience technology. Background technique [0002] By the way, early bicycles were mainly driven by human pedaling, but with the progress of the times, in order to help some users to ride bicycles with electric power assistance, electric bicycles became popular. The early electric bicycles were mainly driven by electric motors. However, in addition to the electric power assist function, many users still expect to retain the riding feeling and sports effect of pedaling. The advent of the electric power assist bicycle. The electric power assist type bicycle is mainly in the process of the user stepping on the pedal, the...
