Abstract

The invention is applied to the field of electric vehicle control, and provides a 485 bus-based electric vehicle control system. The 485 bus-based electric vehicle control system comprises master equipment and slave equipment; the master equipment is used for receiving an operation instruction of a user and transmitting the operation instruction to corresponding slave equipment through a 485 bus; the slave equipment performs a corresponding operation according to the received operation instruction; and the master equipment is also used for receiving an operation result and state information fed back by the slave equipment, processes and displays the operation result and the state information, and simultaneously stores and transmits a processing result to an external system. According to the invention, the mature and reliable 485 bus technology applied in the field of industrial control is introduced into design of a bicycle; one master node and a plurality of slave nodes are connected to form a bus network; the stability and the instantaneity of bus control are sufficiently played; furthermore, the expandability of vehicular body equipment is greatly expanded; therefore, the functions are strong; wiring is less and more attractive; the system is more reliable to operate; the maintenance cost of vehicles is reduced; and because of being more intelligent, the system is simpler to operate and control and better in riding experience.

Description

technical field [0001] The invention belongs to the field of electric vehicle control, and in particular relates to an electric vehicle control system and an address distribution method based on a 485 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 made for comfort and entertainment have made the electric vehicle electrical system a complex system, while there are almost no communication channels in the traditional electric vehicle electrical control system, and all control signals are transmitted by cables, regardless of cost or cost. It is difficult to cope with the complexity and aesthetics. Some high-end electric vehicles or mopeds are equipped with a stopwatch, but ...
