Background technology
World energy sources is fewer and feweri, pollutes more and more serious.Reducing energy resource consumption and reducing discharging is the common recognition of All Around The World.Along with The development in society and economy, the urbanization process of developing country is accelerated, and makes the city automobile owning amount increase fast, causes the aggravation of urban traffic blocking situation, energy resource consumption is risen, and the ratio of the aerial contamination that auto emission causes in urban atmospheric pollution is more and more higher.Self-propelled vehicle also brings the environment difficult problem of many harm humans health when bringing convenient traffic to people, some environmental problem even cause catastrophic event.This is particularly important in developing China, because the most of dependence on import of the crude oil of China, automobile is possessed total amount in continuous increase, and rapid development of economy has made that the pollution of rivers,lakes and seas and air is very serious.So it is imperative to greatly develop the environmentally friendly vehicle of low energy consumption, anti-emission carburetor.The important industry that electronlmobil and hybrid vehicle have also just become countries in the world competitively to develop.
At present, on type of drive, most of electronlmobils adopt the motor direct-drive wheel or drive wheel through a drop-gear box, control fairly simple, but the single speed system is difficult to satisfy the high request of power and speed, usually have only expanded motor and many discharge ponds thereby make that system is huge, Heavy Weight, expense height; For the electronlmobil and the hybrid vehicle that adopt change speed gear box, advantage is a lot, but most of multispeed motor automobile and mixing motor-car adopt an entire car controller, and other adds a gearbox control.
The main effect pure electronic or hybrid power entire car controller (HVCU) of traditional band change speed gear box is to collect the relevant data of battery management system, chaufeur and vehicle to determine power distribution.The controller (TCU) of traditional mechanical automatic gearbox (AMT) is mainly collected the relevant data of chaufeur and vehicle gearshift control is chosen and carried out to best gear.
Same multispeed motor automobile and hybrid vehicle adopt an entire car controller, other adds a gearbox control, this has not only increased cost, also increased wire harness, increased weight, the space requirement of increase, increased system complexity, reduced the reliability of system.And miniaturization, lightweight, low cost, high efficiency, long voyage are the main directions that electronlmobil and hybrid vehicle are extensively promoted.
Summary of the invention
The purpose of this utility model is, there is the problem of controlling diversification according to existing electronlmobil and hybrid vehicle, the utility model discloses a kind of comprehensive intelligent control system at electronlmobil, hybrid vehicle, mechanical automatic gearbox, electron steering and vehicle, i.e. electronlmobil and hybrid vehicle power transmission chain controller.
In fact hybrid vehicle is exactly that a pure electric automobile and a traditional combustion engine locomotive are combined with the form of optimizing.Mix moving ratio to look the size of the size of power of motor and engine power and discuss.When the power of motor on the car equals zero, just become pure traditional vehicle; When the power of driving engine on the car equals zero, just become pure electric automobile.
The realization the technical solution of the utility model is that the utility model electronlmobil and hybrid vehicle power transmission chain controller (HVPCU) are made up of central processing unit, power subsystem unit, signal gathering unit (analog quantity, digital quantity, carrier wave amount), output unit (analog quantity output, switching value output, the output of AMT driver train electric machine control) and communication unit; Power subsystem unit connects the power end of central processing unit; Signal gathering unit connects the input end of central processing unit; Output unit connects the mouth of central processing unit, and communication unit connects the communication interface of central processing unit.
The utility model HVPCU collects relevant data that battery management system, driver's operation and vehicle travel to maximizing solution is made in power distribution, according to the power distribution scheme gearshift control is chosen and carried out to best gear again, simultaneously exerting oneself by the exerting oneself of communication modes control driving engine, electrical motor.HVPCU is not that physics formula ground pieces together entire car controller and Automatic Transmission controller, but the optimization of both circuit and control.
The beneficial effects of the utility model are, the utility model electronlmobil and hybrid vehicle power transmission chain controller (HVPCU) are not only controlled car load but also control change speed gear box, this has not only reduced the cost of controller, also simplify wire harness, alleviated weight, reduced space requirement, simplified system, improved the reliability of system, strided forward major step to the target of electronlmobil miniaturization, lightweight, low cost, high efficiency, long voyage.The more important thing is owing to the optimization of system is feasible the rapidity of power distribution and system, the accuracy of trouble diagnosing are improved.
The utility model is applicable to the comprehensive intelligent control system of electronlmobil, hybrid vehicle, mechanical automatic gearbox, electron steering and the vehicle of band Automatic Transmission.
