【Embodiment】
In order that the purpose of the present invention, technical scheme and advantageous effects become apparent from understanding, below in conjunction with accompanying drawing and
Embodiment, the present invention will be described in further detail.It should be appreciated that the specific implementation described in this specification
Mode is not intended to limit the present invention just for the sake of explaining the present invention.
Referring to Fig. 1, it is the structural principle of the electric automobile control system of air compressor 100 provided in the embodiment of the present invention
Figure.The electric automobile control system of air compressor 100 includes air compressor machine 10, air accumulator 20, automatically controlled drier 30, air compressor machine control
Device 40, instrument 50 and entire car controller 60.Wherein, the air compressor machine 10 is used to produce the gas that compressed gas thinks electric automobile
Dynamic system provides power resources.
The air accumulator 20 is used to store compressed gas caused by the air compressor machine 10 and gather in the air accumulator 20
Pressure value and the pressure value is sent to the automatically controlled drier 30 and the instrument 50 respectively.It is appreciated that the storage
Pressure sensor is provided with gas tank 20 to detect the pressure value in the air accumulator 20.
The automatically controlled drier 30 is used to the pressure value is converted into electric signal and passes to the air compressor controller
40 to control the start and stop of the air compressor machine 10 to work.Specifically, the automatically controlled drier 30 is used for whether judging the pressure value
Less than the first preset value.If the pressure value in the air accumulator 20 is less than the first preset value, the automatically controlled drier 30 is by described in
Pressure value is converted to the first level signal and is sent to the air compressor controller 40, so control the air compressor machine 10 to start with
Produce compressed gas.If the pressure value in the air accumulator 20 is more than or equal to the first preset value, the automatically controlled drier 30
The pressure value is converted into second electrical level signal and is sent to the air compressor controller 40, and then controls the air compressor machine 10
Stop producing compressed gas.In the present embodiment, first level signal is high level signal, the second electrical level signal
For low level signal.
The instrument 50 is used to show the pressure value in the air accumulator 20 and the pressure value is sent into the vehicle
Controller 60.In the present embodiment, the instrument 50 passes through CAN (Controller Area Network, controller local
Network) pressure value is sent to the entire car controller 60 by bus.
The entire car controller 60 is used to receive the pressure value and judge whether the pressure value is less than the second preset value.
If the pressure value is less than the second preset value, the entire car controller 60 sends control instruction to the air compressor controller 40,
And then the air compressor machine 10 is controlled to start to produce compressed gas；If it is default that the pressure value is more than or equal to described second
Value, the entire car controller 60 stop producing the control instruction, that is, the air compressor controller 40 is not by the vehicle control
The control of device 60 processed.In the present embodiment, the entire car controller 60 by CAN (Controller Area Network,
Controller local area network) bus sends the control instruction to the air compressor controller 40.Further, in this embodiment party
In formula, second preset value is less than the first preset value.If it is appreciated that the gas pressure value in the air accumulator 20 is less than institute
The second preset value is stated, then shows the automatically controlled drier 30 or line fault.Now, pneumatic entire car controller 60 is needed to send institute
Control instruction is stated to the air compressor controller 40 to control the air compressor machine 10 further to work.
As shown in Fig. 2 it is the flow chart of the electric automobile air compressor machine control method provided in the embodiment of the present invention.Answer
Illustrate, method of the invention is not limited to the order of following step, and in other embodiment, and method of the invention can be with
A portion of step as described below is only included, or part steps therein can be deleted.
Step S01, produce compressed gas.
Step S02, store the compressed gas and gather the pressure value of the compressed gas.
Step S03, judges whether the pressure value is less than the first preset value；If the pressure value is less than the first preset value,
Then enter step S04；If the pressure value is more than or equal to first preset value, into step S05.
Step S04, the pressure value is converted into the first level signal and is sent to the air compressor controller 40, and then
The air compressor machine 10 is controlled to start to produce compressed gas.In the present embodiment, first level signal is believed for high level
Number.
Step S05, the pressure value is converted into second electrical level signal and is sent to the air compressor controller 40, and then
The air compressor machine 10 is controlled to stop producing compressed gas.In the present embodiment, the second electrical level signal is low level signal.
Step S06, show the pressure value in the air accumulator 20 and the pressure value is sent to the entire car controller
60.In the present embodiment, the instrument 50 is total by CAN (Controller Area Network, controller local area network)
The pressure value is sent to the entire car controller 60 by line.
Step S07, judges whether the pressure value is less than the second preset value.If the pressure value is less than the second preset value,
Then enter step S08；If the pressure value is more than or equal to second preset value, into step S09.
Step S08, control instruction is sent to the air compressor controller 40, and then control the air compressor machine 10 to start to produce
Raw compressed gas.
Step S09, stop producing the control instruction.That is, the air compressor controller 40 is not by the full-vehicle control
The control of device 60.In the present embodiment, the entire car controller 60 passes through CAN (Controller Area Network, control
Device LAN processed) bus sends the control instruction to the air compressor controller 40.Further, in present embodiment
In, second preset value is less than the first preset value.
Electric automobile control system of air compressor 100 provided by the present invention and control method, when the automatically controlled drier 30
Or during circuit failure, the entire car controller 60 can send control instruction to control the air compressor controller 40, enter
And the normal start and stop work of the air compressor machine 10 is realized, so as to improve the appearance of the system of electric automobile control system of air compressor 100
The security performance of error rate and vehicle traveling.
The present invention is not restricted to described in specification and embodiment, therefore for the personnel of familiar field
Additional advantage and modification is easily achieved, therefore in the essence of the universal limited without departing substantially from claim and equivalency range
In the case of refreshing and scope, the present invention is not limited to specific details, representational equipment and shown here as the diagram with description
