Vehicle control circuit of micro hub-style electric sweeper

Abstract

The invention discloses a vehicle control circuit of a micro hub-style electric sweeper. The vehicle control circuit of the micro hub-style electric sweeper manly comprises two parts: a vehicle control unit and a motor control unit. The vehicle control unit comprises a system main controller, a signal acquisition module and a sweep mechanism control switch; the motor control unit mainly comprises a motor control circuit, a power driving circuit, a three-phase bridge-type inverter circuit, a driving motor, an overcurrent protection circuit and a rotor position detecting circuit. The vehicle control circuit of the micro hub-style electric sweeper utilizes the electronic differential technology to realize steering control over the vehicle, the system main controller calculates the controlled variable of each hub motor according to the differential control algorithm through collecting relative parameters of the vehicle in running, and the rotatory speed which controls the left hub motor and the right hub motor is directly outputted, to realize stable operation and differential steering of the vehicle. The hub-style brushless direct current motor is adopted to serve as the driving motor, so that the vehicle control circuit of the micro hub-style electric sweeper is in low noise during operation and suitable for working at public places. The vehicle control circuit of the micro hub-style electric sweeper is efficient and practical, convenient to control, energy-saving and environment-friendly and has high anti-interference capacity.

Description

technical field [0001] The invention relates to the field of control systems for environmentally friendly electric vehicles, in particular to a control circuit for a complete vehicle of a miniature hub type electric sweeper. Background technique [0002] With the acceleration of my country's urbanization process, a series of urban environmental sanitation problems will inevitably be brought about in the process of its development. Nowadays, labor costs continue to increase. Using manpower for urban environmental maintenance and cleaning is not only inefficient, but also increases government financial expenditures. At present, the domestic sanitation machinery market demand is increasingly strong, the market prospect is huge, and the supply of sanitation machinery is in short supply, especially the development of small sanitation vehicles that can meet the cleaning needs of narrow roads, entertainment venues, waiting (aircraft) halls, shopping malls and large buildings. . ...

AI Technical Summary

Problems solved by technology

[0003] Public places such as entertainment venues, waiting (aircraft) halls, shopping malls and large buildings have the characteristics of flat ground, dense population, and high mobility of people. Sanitation vehicles will often start, stop, and turn, and it is inconvenient to use large sanitation machines. In view of the garbage in these places It is mainly small-volume garbage such as paper scraps and dust, and the efficiency of using manpower is extremely low. Traditional sanitation electric vehicles use ordinary motors as the drive motors of the vehicles. Vehicles using ordinary drive motors generally adopt complex mechanical transmission structures, resulting in The vehicle has a large shape and structure, so it is not suitable for working in crowded public places such as entertainment venues, waiting (aircraft) halls, shopping malls and large buildings.
