Detailed description of the invention
In order to make those skilled in the art be more fully understood that technical scheme, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.It should be noted that for the ease of understanding and succinct discussion, describe specific embodiment below in conjunction with gas charging system and inflation method, beneficial effect is not repeated to discuss.
Refer to the structure diagram that Fig. 1, Fig. 1 are a kind of specific embodiment of vehicle inflatable system provided by the present invention；Fig. 2 is the structured flowchart of Fig. 1.
Vehicle inflatable system provided by the invention, including electromotor, air compressor machine driven by the engine 20, monitoring engine behavior controller 10, and the gas cylinder 40 inflated by air compressor machine 20.
It addition, in the present embodiment, be provided with electromagnetic valve 30 between air compressor machine 20 and gas cylinder 40, electromagnetic valve 30 is connected with controller 10, controller 10 control it and open and close.Controller 10 is according to the engine behavior information obtained, it is judged that when electromotor is in towing astern state, it is possible to controls electromagnetic valve 30 and connects air compressor machine 20 and gas cylinder 40, and electromotor drives air compressor machine 20 to compress, and then is filled with gases at high pressure to gas cylinder 40.When being in non-towing astern state, it is possible to stop inflation, or determine that inflation is also off inflation according to the concrete pressure condition of gas cylinder 40.
Based on this, controller noted above 10 can be the engine controller that general vehicle is own, and engine controller itself can monitor engine behavior information, it is not necessary to separately sets controller, to reduce the cost of design.Certainly, individually designed controller is to obtain engine behavior information and to judge whether that it is also feasible for being in towing astern.
Towing astern state (overrun) described in literary composition refers to: not stepping on the gas, electromotor is still in running status.Such as, after acceleration, accelerator releasing slides, or slides during descending.Now, electromotor rotates under effect of inertia, does not produce oil consumption.
Controller 10 can judge whether to be in towing astern state according to the work state information of electromotor, such as throttle information.
Visible, gas charging system and inflation method in the present embodiment are when electromotor is in towing astern state, and gas cylinder 40 is inflated.So, following technique effect can be produced:
The first, during electromotor towing astern, oil consumption is not produced, it is clear that now utilize vehicle inertia to drive engine rotation that gas cylinder 40 is inflated, it is possible to save oil consumption, reduce the operating cost of vehicle；
The second, inflate during electromotor towing astern, it is possible to the some mechanical of electromotor can be applied to driving air compressor machine 20 to compress, and then play certain braking action, be equivalent to provide extra braking function, so that braking is rapider.
Above-described embodiment can optimize further, refer to the flow chart that Fig. 3, Fig. 3 are a kind of specific embodiment of vehicle inflatable system provided by the present invention.
Gas charging system can also include being connected with controller 10 and for detecting the pressure-detecting device of gas cylinder 40 pressure, as pressure transducer 401, then pressure-detecting device can by the gas cylinder 40 pressure signal output of detection to controller 10.The minimum pressure values maintaining vehicular pneumatic systems work and maximum pressure value, this minimum pressure values and maximum pressure value is had to determine according to factors such as concrete vehicle, gas cylinder 40 models it addition, predeterminable in controller 10.
Concrete inflation method can carry out in accordance with the following steps:
S1, the minimum pressure values presetting maintenance vehicular pneumatic systems work and maximum pressure value；
S2, detection gas cylinder 40 pressure；
S3, judge detection gas cylinder 40 pressure whether more than minimum pressure values, no, then enter step S6, be, then enter step S4；
S4, judge detection gas cylinder 40 pressure whether less than maximum pressure value, no, then enter step S7, be, then enter step S5；
S5, judge whether electromotor is in towing astern state, be, then enter step S6, no, then enter step S7；
S6, inflate to the gas cylinder 40 of gas charging system；
S7, stopping are inflated to gas cylinder 40.
The controller 10 detection signal according to pressure transducer 401, after comparing with default maximum pressure value, minimum pressure values, outputs control signals to electromagnetic valve 30, to close electromagnetic valve 30, namely carries out step S70 or opens solenoid valve 30, namely carries out step S6.
Additionally, the order of above-mentioned steps S3 and S4 being not construed as limiting, namely carry out the judgement of towing astern state as long as gas cylinder 40 pressure of detection is between maximum pressure value and minimum pressure values, in order to utilize the electromotor inflation being in towing astern state.
This embodiment, is defined in the inflation of towing astern state vehicle, so, on the one hand, when gas cylinder 40 pressure reaches maximum pressure value, even towing astern state is not reinflated yet, to ensure gas cylinder 40 safety；On the other hand, when gas cylinder 40 pressure is less than minimum pressure values, even if being not in towing astern state, it should also inflated, to maintain the properly functioning of vehicle inflatable system.
Gas charging system and inflation method except above-mentioned vehicle, the present invention also provides for a kind of vehicle, gas charging system and pneumatic system including vehicle, gas charging system includes gas cylinder 40, gas cylinder 40 supplies to pneumatic system, and described gas charging system is the gas charging system described in any of the above-described embodiment, owing to above-mentioned gas charging system has above-mentioned technique effect, the gas charging system with this vehicle also has same technique effect, repeats no more herein.
Further, vehicle is specially passenger vehicle.Such as, bus, to run in the general city of bus, its running environment determines that it is often in towing astern state, then oil consumption can be further saved in its inflation.
Above a kind of vehicle provided by the present invention and gas charging system thereof, inflation method are all described in detail.Principles of the invention and embodiment are set forth by specific case used herein, and the explanation of above example is only intended to help to understand method and the core concept thereof of the present invention.It should be pointed out that, for those skilled in the art, under the premise without departing from the principles of the invention, it is also possible to the present invention carries out some improvement and modification, these improve and modify in the protection domain also falling into the claims in the present invention.
