The specific embodiment
Driving refers to engine speed get out of hand, substantially exceeds rated speed of rotation, and driving engine high vibration, sends roar, the emerge phenomenon of the failure of a large amount of black smokes or blue smoke of freeing pipe.Occur after driving phenomenon, along with increasing of engine speed, the leakage loss between injection pump plunger and plunger sleeve reduces, and the diesel oil entering in cylinder increases, and causes the rotating speed of diesel engine to increase again and again, thereby forms vicious circle; Constantly increasing of diesel engine speed, gas cylinder temperature is constantly raise, the swell increment of piston increases, each part movement aggravation of piston rod group, load increases, surpass after its strength limit, by breaking, cylinder body, connecting rod fracture, crankshaft breakdown and the major accident such as piston, cylinder sleeve and cylinder cap be broken.Therefore, must carry out driving protection, shorten the driving time, to reduce the loss to greatest extent as far as possible.　
When carrying out driving protection, be mainly when there is driving at present, by stopping oil spout to reduce engine speed.Yet this mode that stops oil spout that depends on can not be stopped engine speed very effectively, driving protection effect is poor.Especially, when car load is during at descending, car load towing astern turn of engine, engine speed is difficult to containment.As can be seen from Table 1 when the car load low-grade location of 460 horsepowers, engine speed can reach per minute more than 10,000 and even 20,000 turn, if now can not timely and effectively engine speed be contained, has very large potential safety hazard.　
Table 1
In addition, this mode of prior art, only protects driving engine, in conjunction with car load, does not carry out actv. protection.　
Refer to Fig. 1, the invention provides the first embodiment of driving guard method, the executive agent of the present embodiment can be controller.The present embodiment specifically comprises:
Steps A: judge that whether engine speed is more than or equal to the first rotary speed threshold value N1, if so, performs step B.　
The first rotary speed threshold value N1, for starting the rotary speed threshold value of driving protection, when engine speed is more than or equal to the first rotary speed threshold value, illustrates driving phenomenon has occurred, and therefore now performs step B.　
In steps A, if judge engine speed, be less than the first rotary speed threshold value N1, now there is not driving phenomenon in explanation, now can process ends, or with some cycles circulation execution step A, thereby whether Real-Time Monitoring there is driving phenomenon.　
Step B: stop to driving engine oil spout.　
After having there is driving phenomenon, controller (for example ECU) can send and stop oil spout instruction to injection system, thereby injection system is stopped to driving engine oil spout, to reduce engine speed.　
Step C: after the first Preset Time, if judge described engine speed, be less than or equal to the second rotary speed threshold value N2, perform step H, if judge described engine speed, be more than or equal to the 3rd rotary speed threshold value N3, perform step D, if judge described engine speed, be greater than described the second rotary speed threshold value N2 and be less than described the 3rd rotary speed threshold value N3, returning to execution step C.　
By step B, carrying out and stopping after driving engine oil spout, after a period of time, for example several seconds or several cycle of engine, judgement engine speed, if now engine speed is down to and is less than or equal to the second rotary speed threshold value N2, perform step H, namely recover to driving engine oil spout.Visible the second rotary speed threshold value N2 is for finishing the rotary speed threshold value of driving protection.If now engine speed rises to and is more than or equal to the 3rd rotary speed threshold value N3, perform step D, thereby namely start retarder, strengthen drop engine speed dynamics.Visible, the 3rd rotary speed threshold value N3 is for opening the rotary speed threshold value of retarder.If now engine speed is greater than the second rotary speed threshold value N2, and be less than the 3rd rotary speed threshold value N3, continue to keep the state of engine stop oil spout, return to execution step C, thereby after a period of time, continue judgement engine speed.　
Step D: start retarder.　
Retarder is the excitation coil energising generation magnetic field to stator assembly by control circuit, and armature, with system of vehicle transmission part High Rotation Speed cutting magnetic line, produces opposing torque, thereby makes car retardation.　
When the situations such as car load towing astern driving engine; engine speed is too high; now only by stopping oil spout, can not meet reduction of speed demand; therefore in the present invention by start retarder when stopping oil spout; strengthen for example, reduction of speed dynamics when engine speed too high (being more than or equal to the 3rd rotary speed threshold value N3), can carry out better driving protection.During specific implementation, can be for example, to retarder, to send enabled instruction by controller (ECU), to start retarder.　
Step e: after the second Preset Time, judge whether described engine speed is less than or equal to the 4th rotary speed threshold value N4, if so, performs step F, if not, return to execution step E.　
Start retarder in step D after, after a period of time, for example several seconds or several cycle of engine, judge whether engine speed is less than or equal to the 4th rotary speed threshold value N4, if, perform step F, close retarder, visible the 4th rotary speed threshold value N4 is the rotary speed threshold value of closing retarder.If not, illustrate that now engine speed is still higher, return to execution step E, thereby after a period of time, continue judgement engine speed.　
Wherein the second Preset Time can equate with the first Preset Time, also can not wait.　
Step F: close described retarder.　
When engine speed is less than or equal to after the 4th rotary speed threshold value N4, close retarder, now only need be by stopping realizing reduction of speed to driving engine oil spout.During specific implementation, can be for example, to retarder, to send out code by controller (ECU), to close retarder.　
Step G: judge whether described engine speed is less than or equal to the second rotary speed threshold value N2, if so, performs step H, if not, return to execution step C.　
After closing retarder, judge whether engine speed is less than or equal to the second rotary speed threshold value N2, if so, performs step H, recovers to driving engine oil spout, if not, return to execution step C, to realize rejudging whether need to start retarder.　
Step H: recover to driving engine oil spout.　
When engine speed is during lower than the second rotary speed threshold value N2, recover to driving engine oil spout.Specifically can for example, by controller (ECU), to injection system, send oil spout instruction, thereby realize injection system to driving engine oil spout.　
In the present embodiment; the first rotary speed threshold value N1 is the rotary speed threshold value that starts driving protection; the second rotary speed threshold value is for finishing the rotary speed threshold value of driving protection, and the 3rd rotary speed threshold value N3 is for starting the rotary speed threshold value of retarder, and the 4th rotary speed threshold value N4 is the rotary speed threshold value of closing retarder.And these four rotary speed threshold value meet: second rotary speed threshold value N2 < the 4th rotary speed threshold value N4 < the first rotary speed threshold value N1 < the 3rd rotary speed threshold value N3.　
Known by technique scheme, in embodiments of the present invention, not only by stopping the mode of oil spout, reduce engine speed, but by stopping to driving engine oil spout and start two kinds of modes of retarder to be used in conjunction with reduction engine speed, particularly, when judgement engine speed is more than or equal to the first rotary speed threshold value, stop to driving engine oil spout, and after certain hour, judge engine speed, if now engine speed drops to and is less than or equal to the second rotary speed threshold value, recover to driving engine oil spout, if now engine speed rises to and is more than or equal to the 3rd rotary speed threshold value, start retarder, if now engine speed is between the second rotary speed threshold value and the 3rd rotary speed threshold value, continue to keep stopping oil spout state.If started retarder, cycle criterion, is less than or equal to after the 4th rotary speed threshold value until judge engine speed, closes retarder.Obviously, the present embodiment has adopted and has stopped carrying out driving protection, reduction of speed better effects if to driving engine oil spout and the mode that startup retarder matches; especially when car load towing astern driving engine; when namely engine speed is very high, can effectively contains and greatly reduce potential safety hazard by engine speed.　
In addition, the present embodiment can also be selected effectively according to the actual conditions of engine speed the gear of reduction of speed, when engine speed is more than or equal to the second rotary speed threshold value, stop oil spout, when engine speed is more than or equal to the 3rd rotary speed threshold value, when stopping oil spout, open retarder, obviously reduction of speed mode is more excellent.And the present embodiment is not only protected for driving engine, because retarder is arranged on car load, therefore by starting the mode of retarder, car load has also been carried out to protection effectively.　
And the present embodiment, when engine speed is more than or equal to the first rotary speed threshold value N1, stops oil spout, and when being less than or equal to the second rotary speed threshold value N2, recover oil spout, wherein the first rotary speed threshold value N1 is greater than the second rotary speed threshold value N2.Played in this way the effect of stagnant ring.Equally, when engine speed is more than or equal to the 3rd rotary speed threshold value N3, start retarder, when engine speed is less than or equal to the 4th rotary speed threshold value N4, close retarder, wherein the 3rd rotary speed threshold value N3 is greater than the 4th rotary speed threshold value N4.Therefore also played in this way the effect of stagnant ring.　
Step C at the present embodiment specifically can comprise step C1 and step C2:
Step C1: after the first Preset Time, judge whether described engine speed is less than or equal to the second rotary speed threshold value N2, if so, performs step H, if not, performs step C2.　
Step C2: judge whether described engine speed is more than or equal to the 3rd rotary speed threshold value N3, if so, performs step D, if not, return to execution step C1.　
In the present embodiment, when starting retarder, can also first judge the whether state in opening of retarder, for example, before execution step D, the present embodiment also comprises: judge whether to meet simultaneously: current vehicle speed is not less than speed of a motor vehicle threshold value V, and Das Gaspedal aperture is no more than pedal threshold value A PP, if so, carry out described step D.Current vehicle speed is not less than speed of a motor vehicle threshold value, and Das Gaspedal aperture is no more than pedal threshold value, or judges whether to meet simultaneously: current vehicle speed is not less than speed of a motor vehicle threshold value V, Das Gaspedal aperture is no more than pedal threshold value A PP, and retarder, in opening, if so, performs step D.Otherwise, can process ends, or prompting retarder can not opening information.　
In the present embodiment, can be to get engine speed by tachogen, therefore before carrying out the present embodiment, namely before steps A, the present embodiment can also comprise and judges whether fault of tachogen, if not, performs step A.If so, that is to say tachogen et out of order, do not carry out the present embodiment.　
The following describes a preferred embodiment of driving guard method of the present invention.　
Refer to Fig. 2, the invention provides the second embodiment of driving guard method, the present embodiment specifically comprises:
Step I: controller judges whether fault of tachogen, if not, performs step A.　
First by controller, judge whether fault of tachogen, if not, illustrate that tachogen can normally work, therefore perform step A, by tachogen, judge that whether engine speed is too high.If so, tachogen fault is described, now can points out tachogen failure message, or return execution step I rejudge.　
In the present embodiment, controller can be specifically ECU.　
Steps A: controller judges that by tachogen whether engine speed is more than or equal to the first rotary speed threshold value N1, if so, performs step B.Wherein the first rotary speed threshold value N1=2600rpm (rev/min).　
Wherein by tachogen, gather engine speed, controller judges according to the rotating speed of tachogen collection.　
Step B: controller sends and stops oil spout instruction to injection system, and injection system is stopped to driving engine oil spout.　
Now there is driving phenomenon, by stopping reducing engine speed to driving engine oil spout.　
Step C1: after the first Preset Time, controller judges by tachogen whether described engine speed is less than or equal to the second rotary speed threshold value N2, if so, performs step H, if not, performs step C2.The second rotary speed threshold value N2=2000rpm wherein.　
Step C2: controller judges by tachogen whether described engine speed is more than or equal to the 3rd rotary speed threshold value N3, if so, performs step J, if not, returns to execution step C1.The 3rd rotary speed threshold value N3=3000rpm wherein.　
When this step, the determination result is NO, illustrates that engine speed is greater than the second rotary speed threshold value N2 and is less than the 3rd rotary speed threshold value N3, and now maintenance stops oil spout state, and is back to step C1 cycle criterion.　
Step J: controller judges whether to meet simultaneously: current vehicle speed is not less than speed of a motor vehicle threshold value V, and Das Gaspedal aperture is no more than pedal threshold value A PP, if so, performs step D.　
When the speed of a motor vehicle is less than speed of a motor vehicle threshold value V, or Das Gaspedal aperture is while surpassing pedal threshold value A PP, does not allow to open retarder.Now can process ends, or prompting retarder can not opening information.Wherein speed of a motor vehicle threshold value V can be 5km/h, and pedal threshold values APP can be 5%.　
This step can also further judge that whether retarder is in opening, and if so, now retarder, in open mode, just allows execution step D.Otherwise can process ends, or prompting retarder can not opening information.　
Step D: controller sends enabled instruction to retarder, thus retarder started.　
Specifically retarder can be opened to maximum gear.　
Step e: after the second Preset Time, controller judges by tachogen whether described engine speed is less than or equal to the 4th rotary speed threshold value N4, if so, performs step F, if not, returns to execution step E.The 4th rotary speed threshold value N4=2400rpm wherein.　
Step F: controller sends out code to retarder, thus close retarder.　
When engine speed is less than or equal to after the 4th rotary speed threshold value N4, close retarder, now only need be by stopping realizing reduction of speed to driving engine oil spout.　
Step G: controller judges by tachogen whether described engine speed is less than or equal to the second rotary speed threshold value N2, if so, performs step H, if not, returns to execution step C1.　
Step H: controller sends oil spout instruction to injection system, makes injection system to driving engine oil spout.　
The driving guard method that the corresponding embodiment of the present invention provides, the embodiment of the present invention also provides the specific embodiment of driving protection system, and as shown in Figure 3, the present embodiment comprises tachogen 301, controller 302, injection system 303 and retarder 304.　
Wherein, controller 302 is for carrying out: steps A is to step H.　
Steps A: by tachogen 301, judge whether engine speed is more than or equal to the first rotary speed threshold value N1, if so, execution step B.　
Wherein tachogen 301 is for Real-time Collection engine speed, and the engine speed that controller 302 gathers according to tachogen 301 judges.　
The first rotary speed threshold value N1, for starting the rotary speed threshold value of driving protection, when engine speed is more than or equal to the first rotary speed threshold value, illustrates driving phenomenon has occurred, and therefore now performs step B.　
Step B: send and stop oil spout instruction to injection system 303, so that injection system stops to driving engine oil spout.Therefore reduced engine speed.　
Step C: after the first Preset Time, if judge engine speed by tachogen 301, be less than or equal to the second rotary speed threshold value N2, perform step H, if judge engine speed by tachogen 301, be more than or equal to the 3rd rotary speed threshold value N3, perform step D, if judge engine speed by tachogen 301, be greater than the second rotary speed threshold value N2 and be less than the 3rd rotary speed threshold value N3, returning to execution step C.
