Description
Technical field
the invention belongs to technical field of automobile control, particularly relate to a kind of automotive control system.
Background technology
as the main body of highway transportation, orthodox car is faced with the severe challenge of environmental protection and energy shock, and Development of EV has been quite urgent require that.Current electronlmobil is divided into three kinds: pure electric automobile, fuel cell electric vehicle and mixed power electric car.The electronlmobil wherein adopting fuel cell to make main power source is called fuel cell electric vehicle, i.e. Fuel Cell Electric Vehicle (FCEV).It is high that automotive field personage thinks that fuel cell has fuel efficiency, mass-energy is large, power is large, and power-on time is long, long service life, reliability is high, noise is low and do not produce the advantages such as noxious emission, and is a great revolution of auto-industry based on the electronlmobil of fuel cell, is 21 century real pure environmental protection car, being the environmental protection car type of most practical significance, is also the direction of Development of Electric Vehicles from now on.But the control effects of existing automotive control system is not ideal enough.
Summary of the invention
the present invention is exactly for the problems referred to above, provides the automotive control system that a kind of control effects is good.
to achieve these goals, the present invention adopts following technical scheme, the present invention includes fuel cell system, a DC/DC conv, Ni-MH battery bag, electric capacity, the 2nd DC/DC conv, electric machine controller and motor, its structural feature electric machine controller is connected with a DC/DC conv, Ni-MH battery bag, the 2nd DC/DC conv, motor respectively, one DC/DC conv is connected with fuel cell system, and the 2nd DC/DC conv is connected with electric capacity.
as a kind of preferred version, the micro controller system that electric machine controller of the present invention adopts.
as another kind of preferred version, electric capacity of the present invention adopts electrochemical capacitor.
beneficial effect of the present invention.
the present invention reaches good control effects by the organic assembling of fuel cell system, a DC/DC conv, Ni-MH battery bag, electric capacity, the 2nd DC/DC conv, electric machine controller and motor.
Accompanying drawing explanation
in order to make technical matters solved by the invention, technical scheme and beneficial effect clearly understand, below in conjunction with the drawings and the specific embodiments, the present invention is further elaborated.Should be appreciated that detailed description of the invention described herein only in order to explain the present invention, be not intended to limit the present invention.
fig. 1 is schematic block circuit diagram of the present invention.
Detailed description of the invention
as shown in Figure 1, the present invention includes fuel cell system, a DC/DC conv, Ni-MH battery bag, electric capacity, the 2nd DC/DC conv, electric machine controller and motor, electric machine controller is connected with a DC/DC conv, Ni-MH battery bag, the 2nd DC/DC conv, motor respectively, one DC/DC conv is connected with fuel cell system, and the 2nd DC/DC conv is connected with electric capacity.
the micro controller system that described electric machine controller adopts.
described electric capacity adopts electrochemical capacitor.
the control system of fuel cell electric vehicle is described from the angle of distributed layer control system, realize its topological separation to be separated with function, take the intelligent control scheme of hierarchical specifically, from the angle of energy flow and power division, fuel cell, Ni-MH battery and super capacitor 3 kinds of energy sources are jointly as the power resources of car load, wherein fuel cell is by main DC/DC conv, super capacitor, by grid-connected with Ni-MH battery bag after secondary DC/DC converter transform, provides car load high pressure jointly.Fuel cell is as main source of energy, and Ni-MH battery and super capacitor, as auxiliary energy, are played the part of from different roles as car load energy resource system separately under the various states of automobile, and the reasonable distribution of its energy is the key of whole-control system.
intelligent control system has the hierarchical structure of layering, generally has three layers, i.e. organized layer, cooperation layer and execution level.These levels construct, so be different from the Hierarchical Control of Iarge-scale system completely by the principle of " precision increases progressively and successively decreases with intelligence ".
wherein the intelligence of organized layer is the highest, and it comprises chaufeur interpreter, car load dynamic property control decision device and energy management optimizer.Wherein chaufeur interpreter completes the collection of driver's operation information, study and explanation; Car load dynamic property control decision device completes calculating and the decision-making output of car load dynamic torque; Energy management optimizer completes the reasonable distribution of the various energy of car load.Cooperation layer is the interface between the organized layer of high intelligence and the execution level of low intelligence, and its basic mission is to execution level the message scheduling of organized layer.Fuel cell controller, electric machine controller, DC/DC conv, battery management system and high tension distribution system etc. all belong to the category of cooperation layer.Organized layer and cooperation layer adopt optical fiber CAN bus to communicate, and greatly strengthen antijamming capability.Execution level is the lowermost layer of hierarchical Based Intelligent Control, and its intelligence is minimum but precision is the highest.It mainly completes detection and the collection of data, and performs the control command of corresponding cooperation layer, and the status information that feedback is current in time.
above content is the further description done the present invention in conjunction with concrete preferred implementation; can not assert that specific embodiment of the invention is confined to these explanations; for general technical staff of the technical field of the invention; without departing from the inventive concept of the premise; some simple deduction or replace can also be made, all should be considered as belonging to the protection domain that claims that the present invention submits to are determined.
