Specific embodiment
Exemplary embodiments of the present disclosure are described in more detail below with reference to accompanying drawings.Although showing the disclosure in attached drawing
Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here
It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure
It is fully disclosed to those skilled in the art.
Embodiment one
The embodiment of the present invention one provides a kind of motor boat hypervelocity control method, as shown in Figure 1, comprising: S101, acquisition rub
Hold in the palm the revolving speed of ship；S102 judges whether the revolving speed is more than preset hypervelocity control point；S103 is more than hypervelocity control in the revolving speed
When point, judge whether the motor boat is in effluent state i.e.；S104, when determining that the motor boat is in effluent state i.e.,
According to current revolving speed and corresponding revolving speed correction factor, the revolving speed of motor boat hypervelocity threshold values area locating after water outlet is determined
Domain；S105 is based on the hypervelocity threshold values region, and the multiple oil cylinders for controlling motor boat carry out point cylinder oil-break and corresponding igniter stops
Fire.
In specific real-time mode, specifically, in S101, the revolving speed of motor boat is obtained, especially by motor boat
The signal that the speed probe of setting detects, come determine motor boat engine revolving speed, so that it is determined that the revolving speed of motor boat.
The revolution speed sensing implement body can be crankshaft position sensor.
Then, execute S102, judge the revolving speed whether be more than setting hypervelocity control point, at this point, motor boat is also in water
In, which specifically can be 7500~7900r/min, specifically can be 7500r/min.
Then, S103 is executed, when the revolving speed is more than hypervelocity control point, judging whether the motor boat is in will be watery out
State.
Firstly, the revolving speed of the motor boat has been an overspeed condition, will be discharged judging whether the motor boat is in
When state, determined according to the signal for the water sensor acquisition being arranged on the hull of motor boat.The water sensor specifically can be
Water level sensor or hydraulic pressure sensor, for detecting the load variation of motor boat.
For water level sensor, when the load reduction of motor boat, that is, the water level detected is to reduce, so that it is determined that rubbing
Ship is ask to be in effluent state i.e.；When the load increase of motor boat, that is, detect that water level is to increase, so that it is determined that motor boat is in
Water state will be entered.
For hydraulic pressure sensor, when the load increase of motor boat, that is, detect that hydraulic pressure increases, it is determined that at motor boat
In water state will be entered；When the load reduction of motor boat, that is, detect that hydraulic pressure reduces, it is determined that motor boat is in will be watery out
State.
S104 is executed, when determining that motor boat is in effluent state i.e., according to current revolving speed and corresponding revolving speed
Correction factor determines the revolving speed of motor boat hypervelocity threshold values region locating after water outlet.
Specifically, when determining that the motor boat is in effluent state i.e., the speed probe inspection of current motor boat is obtained
The revolving speed measured；Then the revolving speed speed probe detected adds corresponding revolving speed correction factor, obtains the motor boat
Transient speed in water outlet；Based on the transient speed, hypervelocity threshold values region locating for the transient speed of the motor boat is determined.
Due to the motor boat moment that state is discharged in by water, the resistance of water is overcome, the transient speed after water outlet is very big, than
The speed at hypervelocity control point when in water is also big, therefore, rule of thumb, obtains the revolving speed correction factor of basis calibration.Root
According to the revolving speed that the speed probe of current time motor boat detects, it is right to obtain the revolving speed institute that the corresponding speed probe detects
The revolving speed correction factor answered, for example, the revolving speed that the speed probe of current time motor boat detects is 7500r/min, then it is right
The revolving speed correction factor answered is 500r/min；If the revolving speed that the speed probe of current time motor boat detects is 7800r/
Min, then corresponding revolving speed correction factor is 800r/min.
After obtaining revolving speed correction factor corresponding with the revolving speed that the speed probe of current time motor boat detects,
By the way that corresponding revolving speed correction factor will be added in the revolving speed of current time motor boat, motor boat turn instantaneous in water outlet is obtained
Speed.According to above-mentioned example, the water outlet transient speed for obtaining motor boat is 7500+500=8000r/min, 7800+800=
8600r/min。
Transient speed when being discharged according to motor boat, so that it is determined that hypervelocity threshold values area locating for the transient speed of motor boat
Domain.For example, hypervelocity threshold values region locating for the transient speed of 8000r/min is to be less than or wait greater than 7900 in above-mentioned example
In 8200r/min, hypervelocity threshold values region locating for the transient speed of 8600r/min is to be less than or equal to 8600r/ greater than 8400
min。
After the hypervelocity threshold values region of motor boat has been determined, S105 is executed, the hypervelocity threshold values region is based on, controls this and rub
Multiple oil cylinders of support ship carry out point cylinder oil-break and corresponding igniter is ceased fire.
Specifically, firstly, based on hypervelocity threshold values region, hypervelocity control section corresponding to hypervelocity threshold values region is obtained；Then,
Based on corresponding hypervelocity control section, igniting interrupt instruction and oil spout interrupt instruction are sequentially output to multiple oil cylinders of motor boat；Most
Afterwards, it is based on the igniting interrupt instruction and oil spout interrupt instruction, the multiple oil cylinders for controlling the motor boat carry out point cylinder oil-break and right
The igniter answered is ceased fire.
It is exemplified below in different hypervelocity control sections, divides cylinder oil-break and right to what multiple oil cylinders of motor boat carried out
The control that the igniter answered is ceased fire.
| It exceeds the speed limit control section (r/min) | Control measure |
| ≤ 7900 | Normal oil spout and igniting |
| > 7900 and≤8200 | Disconnected 1 cylinder igniting and oil spout |
| > 8200 and≤8400 | Disconnected 1,2 cylinders igniting and oil spout |
| > 8400 and≤8600 | Disconnected 1,2,3 cylinders igniting and oil spout |
| >8600 | Disconnected 1,2,3,4 cylinders igniting and oil spout |
It is controlled, more effectively the hypervelocity stage can be controlled using sectional, ensure that motor boat drove
Safety and driving experience.
After S105, further includes: be gradually decrease to hypervelocity control point in the revolving speed for detecting motor boat or surpass lower than this
Fast control point, and motor boat is in when will enter water state, control restores multiple oil cylinder oil spouts and corresponding igniter fire.
In this way, can be too fast with the decline of revolving speed caused by the resistance of partial offset water, and then can add in advance when motor boat will enter water
The driving experience of motor boat can be improved to avoid the sharply decline of motor boat revolving speed after entering water in speed.
