Intelligent power-assisted controller of electric bicycle

Abstract

The invention discloses an intelligent power-assisted controller of an electric bicycle. The intelligent power-assisted controller comprises a signal processing and center control module, a power-assisted signal collecting module and a motor drive module; the power-assisted signal collecting module comprises a torque sensor and an acceleration sensor which are connected to the signal processing and center control module; the motor drive module comprises a PWM (pulse-width modulation) drive circuit connected to the signal processing and center control module, and a direct current motor connected with the PWM drive circuit. According to the invention, the bicycle can be driven to run by combined man-machine force; proper electric power-assisting energy is automatically provided according to the size of the driving pedal force of a person and the change of road condition resistance; the expenditure of a battery is saved, and prolonging of the endurance mileage is facilitated, so that the amusement and use property are obviously improved with the common participation of manpower.

Description

technical field [0001] The invention relates to a controller, in particular to an electric bicycle booster controller. Background technique [0002] As we all know, in mainland China, the mainstream mode of electric bicycles is all-electric driving. The main reason is that in the mainland market, electric bicycles are not leisure products, but transportation tools. Consumers feel that it is worthless to pedal manually. In the all-electric mode, the handle can be turned and walked away, saving trouble and effort. In the international market, both Europe and the United States require electric bicycles with pedals to start, pedals to stop and power off, and no handlebars. The Japanese market needs electric bicycles with precise proportional power assistance. [0003] At present, there are still many problems in the design of my country's electric bicycles in the intelligent booster system and controller, which cannot meet foreign technical standards, which has become an obsta...

Problems solved by technology

[0003] At present, there are still many problems in the design of my country's electric bicycles in the intelligent booster system and controller, which cannot meet foreign technical standards, which has become an obstacle for my country's products to go abroad and a bottleneck restricting the international development of my country's electric bicycle industry.

[0004] Most electric bicycle controllers in my country use electronic, stepless variable frequency pulse width debugging. This method has a relatively low level of intelligence, and the riding effect is not smooth; while the intelligent controller proposed by my country's electric bicycles exported to European and American markets is actually just a speed switch. Type control or simple speed-based control, cancel the original handle, install a Hall element and a magnetic steel disc on the central axis, and the motor will start when it reaches a certain speed. After starting, it will be fully electric control, so it has no As for the precise ratio, the riding feeling is also poor
