Embodiment
In order to make those skilled in the art understand better technological scheme of the present invention, 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, below describe specific embodiment in conjunction with gas charging system and inflation method, beneficial effect no longer repeats to discuss.
Please refer to Fig. 1, Fig. 1 is the structure diagram of a kind of specific embodiment of vehicle gas charging system provided by the present invention; Fig. 2 is the structured flowchart of Fig. 1.
Vehicle gas charging system provided by the invention, comprises motor, controller 10 by engine-driven air compressor 20, monitoring engine behavior, and the gas cylinder 40 of being inflated by air compressor 20.
In addition, in the present embodiment, between air compressor 20 and gas cylinder 40, be provided with solenoid valve 30, solenoid valve 30 is connected with controller 10, controls its opening and closing by controller 10.Controller 10, according to the engine behavior information obtaining, judges that motor is in the time of towing astern state, can control solenoid valve 30 and connect air compressor 20 and gas cylinder 40, and engine-driving air compressor 20 compresses, and then is filled with pressurized gas to gas cylinder 40.In the time of non-towing astern state, can stop inflation, or determine that according to the concrete pressure condition of gas cylinder 40 inflation still stops inflation.
Based on this, above-mentioned controller 10 can be the own engine controller of general vehicle, and engine controller meeting monitoring engine work state information itself, without separately establishing controller, to reduce the cost of design.Certainly, CONTROLLER DESIGN is also feasible to obtain engine behavior information and to judge whether in towing astern separately.
Towing astern state (overrun) described in literary composition refers to: do not step on the gas, motor is still in running state.Such as, after accelerating, accelerator releasing slides, or slides when descending.Now, motor rotates under effect of inertia, does not produce oil consumption.
Controller 10 can judge whether in towing astern state according to the work state information of motor, such as throttle information.
Visible, the gas charging system in the present embodiment and inflation method are, gas cylinder 40 to be inflated during in towing astern state at motor.So, can produce following technique effect:
The first, when motor towing astern, do not produce oil consumption, obviously, now utilize vehicle inertia to drive engine rotation to inflate gas cylinder 40, can save oil consumption, reduce the operating cost of vehicle;
The second, inflate when motor towing astern, the part mechanical energy of motor can be applied to and drive air compressor 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 further be optimized, and please refer to Fig. 3, and Fig. 3 is the flow chart of a kind of specific embodiment of vehicle gas charging system provided by the present invention.
Gas charging system can also comprise and being connected with controller 10 and for detection of the pressure-detecting device of gas cylinder 40 pressure, as pressure transducer 401, pressure-detecting device can export the gas cylinder of detection 40 pressure signals to controller 10.In addition, controller 10 interior predeterminable the have minimum pressure values and the maximum pressure value that maintain vehicle launch system works, this minimum pressure values and maximum pressure value are determined according to factors such as concrete vehicle, gas cylinder 40 models.
Concrete inflation method can carry out in accordance with the following steps:
S1, default minimum pressure values and the maximum pressure value that maintains vehicle launch system works;
S2, detection gas cylinder 40 pressure;
S3, judge detect gas cylinder 40 pressure whether be greater than minimum pressure values, no, enter step S6, be to enter step S4;
S4, judge detect gas cylinder 40 pressure whether be less than maximum pressure value, no, enter step S7, be to enter step S5;
S5, judge that motor, whether in towing astern state, is, enter step S6, no, enter step S7;
S6, inflate to the gas cylinder 40 of gas charging system;
S7, stop inflating to gas cylinder 40.
Controller 10 is according to the testing signal of pressure transducer 401, with default maximum pressure value, minimum pressure values relatively after, output control signals to solenoid valve 30, with shut electromagnetic valve 30, carry out step S70, or opens solenoid valve 30, carry out step S6.
In addition, the order of above-mentioned steps S3 and S4 is also not construed as limiting, as long as gas cylinder 40 pressure that detect carry out the judgement of towing astern state between maximum pressure value and minimum pressure values, to utilize the motor inflation in towing astern state.
This embodiment, limits in the inflation of towing astern state vehicle, so, on the one hand, in the time that gas cylinder 40 pressure reach maximum pressure value, even the also no longer inflation of towing astern state, to ensure gas cylinder 40 safety; On the other hand, when gas cylinder 40 pressure are less than minimum pressure values, even not in towing astern state, also should be inflated, to maintain the normal operation of vehicle gas charging system.
Except gas charging system and the inflation method of above-mentioned vehicle, the present invention also provides a kind of vehicle, comprise gas charging system and the pneumatic system of vehicle, gas charging system comprises gas cylinder 40, gas cylinder 40 air feed are to pneumatic system, and described gas charging system is the gas charging system described in above-mentioned arbitrary embodiment, because 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, operation in the general city of bus, its running environment determines that it is often in towing astern state, 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.Applied specific case herein principle of the present invention and mode of execution are set forth, above embodiment's explanation is just for helping to understand method of the present invention and core concept thereof.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also carry out some improvement and modification to the present invention, these improvement and modification also fall in the protection domain of the claims in the present invention.
