Abstract

The invention belongs to the field of electric bicycle control, and provides an electric bicycle control system based on a CAN bus. The electric bicycle control system comprises a stopwatch unit and units connected with the stopwatch unit. The stopwatch unit is used for receiving an operation instruction of a user and transmitting the operation instruction of the user to the corresponding units through the CAN bus. The corresponding units conduct corresponding operations according to the received operation instruction. The stopwatch unit is further used for receiving operation results and status information fed back by the units to be processed, and meanwhile the processed results are stored and transmitted to an external system. According to the electric bicycle control system, the CAN bus technology maturely and reliably applied in the field of industrial control is introduced into the design of a bicycle, bicycle body equipment is connected together to form a bus network, stability and real-time performance of bus control are brought into full play, and the expandability of the bicycle body equipment is greatly improved, so that functions are stronger, fewer wires are adopted, wiring is more attractive, system operation is more reliable, and the bicycle maintenance cost is lowered; the electric bicycle control system is more intelligent, easier to control and better in riding experience.

Description

technical field [0001] The invention belongs to the field of electric vehicle control, in particular to an electric vehicle control system based on a CAN bus. Background technique [0002] In modern electric bicycles, especially power-assisted bicycles and smart bicycles, the body equipment is gradually increasing with the continuous improvement of people's demand for various functions of bicycles, ranging from motor control, safety assurance system, alarm system, stopwatch, and improved cycling. Various efforts made for comfort and entertainment, the addition of a large number of sensors and controllers make the electric vehicle electrical system form a complex system, while there are almost no communication channels in the traditional electric vehicle electrical control system, and all control signals rely on Cable transmission is difficult to deal with in terms of cost, complexity and aesthetics. Some high-end electric vehicles or mopeds are equipped with a computer, but...
