Abstract

The present invention is applicable to the field of electric vehicle control, and provides a CAN bus-based electric vehicle control system, including a code table unit and various units connected thereto; the code table unit is used to receive user operation instructions and transmit them to the Corresponding units, the corresponding units perform corresponding operations according to the received operation instructions; the code table unit is also used to receive the operation results and status information fed back from each unit for processing, and at the same time store and transmit the processing results to the external system. The invention introduces the mature and reliable CAN bus technology in the field of industrial control into bicycle design, connects the body equipment to form a bus network, fully exerts the stability and real-time performance of bus control, and greatly expands the scalability of the body equipment. The function is stronger, the wiring is less and more beautiful, the system operation is more reliable, and the maintenance cost of the vehicle is reduced; it is more intelligent, so the control is easier and the riding experience is better.

Description

technical field [0001] The invention belongs to the field of electric vehicle control, in particular to an electric vehicle control system based on CAN bus. Background technique [0002] In modern electric bicycles, especially power-assisted bicycles and smart bicycles, body equipment is gradually increasing with the continuous improvement of people's requirements for various functions of bicycles, from motor control, safety assurance system, alarm system, stopwatch, and improving riding Various efforts have been made for comfort and entertainment, and the addition of a large number of sensors and controllers has made the electric vehicle electrical system a complex system. However, 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 cope with in terms of cost, complexity, and aesthetics. Some high-end electric vehicles or mopeds are equipped with a stopw...
