Embodiment 1

[0058] Embodiment 1. A digital differential moped system with comparators added to gear and speed signals

[0059] Such as figure 1 , 2, including two wheels of an electric assist bicycle: wheel A and wheel B, and a motor A driving wheel A and a motor B driving wheel B, including a manual controller 3 of the electric assist bicycle, characterized in that: it also includes a differential controller 1, the vehicle speed signal sensor 12 and the speed equalizer 20; the vehicle speed signal sensor 12 is connected with the speed equalizer 20, and the speed equalizer 20 is a signal processing that changes the speed signal of the vehicle speed signal sensor 12 within a certain period of time into the average speed within the certain period of time device.

[0060] The differential controller 1 is connected with the motor A by the controller A, and the controller A uses the control signal given by the differential controller 1 to control the power supply to supply power to the wheel...

Embodiment 2

[0082] Embodiment 2, a digital differential moped system with a corner parameter processor that adds both gear and speed signals to a comparator

[0083] Such as image 3 , 4 , as the whole structure of embodiment 1, and IA>IB differential model data processor 7 and IA

[0084] A pressure sensor is arranged on the human seat cushion of the power-assisted bicycle, or on the elastic part connected with the cushion, and the pressure sensor is connected with the data distributor 10 in the differential controller 1, and the pressure signal of the pressure sensor is respectively sent to two data distributors in the data distributor 10. The control digital signals are processed in the same proportion to increase or the same proportion to decrease.

Abstract

In the present invention, the digital differential power-assisted bicycle system in which both the gear position and the speed signal are added to the comparator belongs to the power supply controller system of the front wheel and the rear wheel with differential distribution of power-assisted power supply. It includes two wheels and two motors of the electric power-assisted bicycle, a manual controller for the gear signal, and a differential controller. The differential controller includes three modules connected in sequence; the first module controls the gear position of the manual controller for the gear signal. The signal ID, the vehicle average speed signal IS of the speed equalizer, the feedback control signal current IA and IB are numerically compared and processed; the second module uses the set model function to perform model function processing on the data of the first module; the third module controls The data not only includes elements of gear position signal ID, feedback control signal current IA and IB, but also four elements of vehicle average speed signal IS. Advantages: Differentially control and supply power to the two motors of the front and rear wheels of the power-assisted bicycle. The content of the differential control is the pre-set model function processing.

Description

technical field [0001] The invention belongs to a booster controller system of an electric power-assisted bicycle, in particular to a power supply controller system for a bicycle with differential power distribution between the front wheel and the rear wheel for differential power supply. Background technique [0002] The Chinese patent 201210011641.8 applied by Hunan Shengtong Technology Group Co., Ltd. proposes a dual hub motor drive system adaptive balance steering control method, but does not provide the technical design of a special processor for electronic differential. [0003] The Chinese patent 201110358020.2 applied by Hunan Shengtong Technology Group Co., Ltd. is a centralized controller for electronic differential speed and speed regulation of dual hub motors, but there is no specific design of the electronic differential speed module. [0004] Co., Ltd. Hitachi Manufacturing Co., Ltd. 01122460.6 This paper discloses a transmission, which includes a mechanism for...
