Then, utilize Fig. 7 to inform that to controlling to slow down the deceleration of lighting and extinguishing of lamp 10 informs that handling part 5 describes.This deceleration inform handling part 5 at the Internal architecture of the control unit as computer unit software.Slow down inform handling part 5 comprise that controlling slows down and inform lighting of lamp 10 and extinguish inform lamp control part 51, calculate the deceleration/decel of vehicle deceleration/decel calculating part 50, judge that vehicle is that on the road of (operation travel in) detection unit 52 travels in travel/field on the way travelling or in travelling in field.In addition, slow down and inform that lamp 10 is also also used as stoplight stop lamp, therefore also to informing that 51 inputs of lamp control part detect the detection signal of the braking sensor of trampling operation 97 of brake pedal 84.
Detection unit 52 input of travelling from travel/field, operating condition test section 92Xiang road represents the whether operating condition signal in operation of vehicles, and detection unit 52 inputs of travelling from travel/field, shift position test section 93Xiang road represent the speed change state signal of the speed change state of Poewr transmission mechanisms 2.Operating condition test section 92 based on from detect operation power-transfer clutch 40 engaging/disengaging state operation clutch sensor 94 operation power-transfer clutch detection signal and from the vehicle speed signal of speed of a motor vehicle test section 96, generate operating condition signal.Speed of a motor vehicle test section 96 generates vehicle speed signal according to the detection signal from tachogen 96a, and tachogen 96a detects gear (gear of for example differentiator) rotating speed that represents the rotating speed after Poewr transmission mechanism 2 speed changes.Shift position test section 93 generates speed change state signal according to the detection signal from secondary speed change sensor 93b, and change gear transmission (secondary speed-changing device) 2B that secondary speed change sensor 93b detects two grades of height is which shift position in high speed gear or low gear.The result of determination of travelling in detection unit 52 in travel on road/field is transported to deceleration/decel calculating part 50.
The detection signal that detects the main transformer speed sensor 93a of the operation displacement of main shift lever 81 is imported into deceleration/decel calculating part 50, and the swash plate regulating mechanism 24 that main shift lever 81 operates Hydraulic Pump 21 changes the speed of a motor vehicle.In addition, input vehicle speed signal from speed of a motor vehicle test section 96 to deceleration/decel calculating part 50.Deceleration/decel calculating part 50 calculates the deceleration/decel of vehicle to the operation displacement of deceleration direction according to main shift lever 81, but use displacement/deceleration/decel transition diagram of deriving deceleration/decel according to operation displacement at this.As displacement/deceleration/decel transition diagram, both can derive the deceleration/decel based on this operation displacement according to two operation displacements of obtaining continuously, also can be to obtain operation all to calculate the speed of a motor vehicle corresponding with this operation displacement when displacement at every turn, derive deceleration/decel according to the difference between the speed of a motor vehicle corresponding with the operation displacement of interval acquiring continuously.Now, displacement/deceleration/decel transition diagram of utilizing is according to the vehicle speed signal of obtaining from speed of a motor vehicle test section 96, namely the speed of a motor vehicle in this moment changes.That is to say, in the situation that the speed of a motor vehicle is fast, derive larger deceleration/decel compared with the situation slow with the speed of a motor vehicle, thus improve the essentiality of informing of slowing down high run at high speed time relevance grade.
In this embodiment, deceleration/decel calculating part 50 comprises displacement variable calculating part 53.Displacement variable calculating part 53 displacement calculating variable quantities, this displacement variable is the operation displacement to deceleration direction of obtaining the continuously variable quantity within the unit time.According to the displacement variable calculating, use displacement variable/deceleration/decel transition diagram, derive deceleration/decel.The operation displacement sharply of main shift lever 81 in deceleration direction causes deceleration sharply, operates slowly displacement and causes slowing down slowly, in view of this, calculates deceleration/decel be also good according to this displacement variable.
Be which in operation displacement or displacement variable to calculate deceleration/decel according on earth, both can manually set, also can automatically select according to vehicle-state (speed of a motor vehicle, operation are travelled, travel on road etc.).Or can also prepare all derives displacement displacement variable/deceleration/decel transition diagram of deceleration/decel using operating displacement and displacement variable both sides as input parameter, make deceleration/decel calculating part 50 calculate deceleration/decel according to operation displacement and displacement variable.The as prescribed speed of a motor vehicle is prepared out multiple such figure, selects according to the speed of a motor vehicle detecting.
In this embodiment, deceleration/decel calculating part 50 is also transfused to from the travel result of determination of detection unit 52 of travel on road/field.Be divided into two kinds from the travel mode of utilizing of result of determination of detection unit 52 of travel on road/field.Wherein one is, in the situation that being judged to be field and travelling, does not send the mode of slowing down and reporting to the police in the time slowing down to outside.Another is, while on the way travelling and while travel in field, to change the mode of the displacement/deceleration/decel transition diagram using.
Inform the deceleration/decel that lamp control part 51 calculates deceleration/decel calculating part 50 and be set as deceleration the threshold value comparison of lighting decision condition of informing lamp 10, in the situation that deceleration/decel exceedes threshold value, namely, in the situation that lighting decision condition establishment, lighting slows down informs lamp 10.In this embodiment, from speed of a motor vehicle test section 96 to informing that lamp control part 51 inputs vehicle speed signal, change threshold value according to the speed of a motor vehicle.For example, in the time running at high speed, during with low speed driving compared with reduction threshold criteria, more easily lighting slows down informs lamp 10.
For example, enumerate concrete reference example, the in the situation that of this maize harvesting machine, while travelling, be used as the moderating ratio of deceleration/decel on the road of speed per hour about 10 to 25Km, light to slow down using moderating ratio=-1.2Km/0.2 second as threshold value and inform lamp 10.In addition, while travelling in the field in speed per hour 10Km, light to slow down using moderating ratio=-1.6Km/0.2 second as threshold value and inform lamp 10.
Informing that lamp control part 51 also has based on the condition of extinguishing makes the deceleration of lighting based on ignition condition inform the function that lamp 10 extinguishes.In the situation that adopting simple structure, inform that in the case of lighting to slow down the deceleration/decel calculating after lamp 10 does not exceed threshold value, make to slow down and inform that lamp 10 extinguishes.The deceleration of in this embodiment, informing lamp control part 51 inform lamp 10 extinguish decision condition and to light decision condition different.Specifically, light decision condition and light and slow down while informing lamp 10 meeting, even if the discontented bright decision condition of foot point afterwards does not make to slow down yet and informs that lamp 10 extinguishes.Make to slow down and inform that lamp 10 extinguishes, just need to meet than light decision condition looser extinguish decision condition, and need to be discontented with the bright decision condition of foot point through specified time from becoming.At this, extinguishing decision condition ratio, to light decision condition looser, refers to that the standard of the threshold value compared with deceleration/decel is lower.In this embodiment, lighting decision condition first is lighted decision condition and second and lights decision condition and form by what change according to the speed of a motor vehicle.How extinguish decision condition can the speed of a motor vehicle all fix, but exists with ... light decision condition in the situation that making to extinguish decision condition, extinguishes decision condition and also changes according to the speed of a motor vehicle.
In the functional block diagram of Fig. 7, as other modes of the operation displacement of inputting to deceleration/decel calculating part 50, also make to be shown in broken lines the operation displacement being detected by throttle sensor 95 or 95a.Throttle sensor 95 detects the operation displacement of Das Gaspedal 83, and throttle sensor 95a detects the operation displacement of throttle lever 83a.When make engine speed occur to decline by the operation of Das Gaspedal 83 or throttle lever 83a, the rotating speed of the power of inputting to transmission system 2A also declines, and is that transmission system 2A is to deceleration regime transition from the results of view.Therefore, the same with the operation displacement of main shift lever 81, calculate deceleration/decel and lighting control and also can realizing of lamp 10 informed in the deceleration carried out based on this deceleration/decel based on the operation displacement of Das Gaspedal 83 or throttle lever 83a.Now, according to being the operation displacement being produced by main shift lever 81 or the operation displacement being produced by Das Gaspedal 83 or throttle lever 83a, change the displacement/deceleration/decel transition diagram or the displacement variable/deceleration/decel transition diagram that in deceleration/decel calculating part 50, use.
Then, illustrate that above-mentioned deceleration informs that handling part 5 informs that to slowing down lighting of lamp 10 extinguish an example of control.First, use Fig. 8 schematic view illustrating this light the basic procedure that extinguishes control.
According to the speed of a motor vehicle to reduce the variable speed operation evaluation that relevant operative position in-migration calculates deceleration/decel be that the repeated freqnency specifying is carried out.In this variable speed operation is evaluated, meet (#a) light decision condition in the situation that at deceleration/decel, regard as and produced the deceleration that should arouse attention, lighting slows down informs lamp 10 (#b), waits for next variable speed operation evaluation (#c).The in the situation that of the discontented bright decision condition of foot point of deceleration/decel (#d), regard as and do not need the deceleration that arouses attention, inform that depending on slowing down lamp 10 is to carry out different processing in illuminating state or in extinguishing state.Now, inform that lamp 10 is in extinguishing state if slowed down, keep intact what does not do, wait for next variable speed operation evaluation (#e).Now, inform that lamp 10 is in illuminating state if slowed down, to extinguishing new field of technical activity transition (#f).Extinguishing the new field of technical activity, checking whether to meet and extinguish decision condition.Extinguish decision condition (#g) if meet, extinguishing slows down informs lamp 10 (#h), waits for next variable speed operation evaluation (#j).If do not meet and extinguish decision condition (#k), keep intact what does not do, wait for next variable speed operation evaluation (#m).
The flow process of Fig. 9, Figure 10, Figure 11 there is shown the above-mentioned example of extinguishing the specific control of the basic procedure of control of lighting.
Fig. 9 slows down to inform the host process of processing.As pre-processing, obtain at least one (#01) in vehicle speed signal, gear signal, operation power-transfer clutch detection signal.According to this signal obtaining, judge that vehicle is on road, to travel or field travel (#02).In the time being judged to be to travel on road, carrying out makes to slow down informs that lamp 10 is lighted and while travelling on the road that deceleration that the bright processing of time point (#03) and making of travelling on the road to inform deceleration to outside lights informs that lamp 10 extinguishes, extinguishes processing (#05).In the time being judged to be field and travelling, carry out to light while travelling in field and while travelling in processing (#07) and field, extinguish processing (#09).In addition, while travelling in field, not using slows down informs that the deceleration of lamp 10 informs processing, omits to light while travelling in field and while travelling in processing (#07) and field, extinguishes processing (#09).
Then, utilize the bright processing of time point of travelling on satisfying the need of the diagram of circuit of Figure 10 to describe.
First,, after the operation displacement of obtaining main shift lever 81 (#31), the displacement difference (representing with Δ d in Figure 10) between the operation displacement of calculating and obtaining last time (#32).The displacement difference calculating is compared with the δ that represents predefined immunity region, and in the situation that displacement difference does not exceed δ, (the no branch of #33), ignores this displacement, finishes this process.In the situation that displacement difference exceedes δ (#33 is branch), utilize deceleration/decel calculating part 50 to calculate deceleration/decel.In the computation process of deceleration/decel, to use the figure that derives deceleration/decel according to displacement difference, in the time being expressed as formula, for:
R＝Gr(Δd，α1···)。
At this, R represents deceleration/decel, and α 1 represents other input parameters such as the speed of a motor vehicle, also can omit.
Informing in lamp control part 51, set the threshold value for lighting judgement.Threshold value can be fixed value, and at this, threshold value can be also to pass through the speed of a motor vehicle: the variation value that v, other input parameters: β 1 calculate, in this case, and by threshold value: when S1 is formulated, for:
S1＝S(v，β1···)。
Deceleration/decel is compared with threshold value (#41), exceed threshold value and when making to light decision condition and setting up (#41 is branch) at deceleration/decel, further check light mark be whether " 0 " (being set as " 0 " in initial setting) (#42).Be masked as " 0 " (#42 is branch) if lighted, in this moment, slow down and inform that lamp 10 is going out, therefore, lighting slows down informs lamp 10 (#43), will light mark and be set as " 1 " (#44), finishes this process.Be masked as " 1 " (the no branch of #42) if lighted, slow down and inform that lamp 10 has been lit, therefore keeping intact, what does not do and finishes this process.
Making to light decision condition if deceleration/decel does not exceed threshold value is false (the no branch of #41), further check light mark be whether " 1 " (#45).Be masked as " 1 " (#45 is branch) if lighted, start time meter to start the timing for extinguishing, be used as making the now deceleration of light yellow to inform the preparation processing (#46) that lamp extinguishes with this, to extinguish mark and be set as " 1 " (#47), finish this process.
Figure 11 represents to travel on and then road and while travelling on the road that the bright processing of time point carries out, extinguishes the diagram of circuit of processing.In this processing, whether first, detecting and lighting mark is " 1 ", informs the whether positive light yellow (#51) of lamp 10 to check now to slow down.Lighting mark for " 1 ", (the no branch of #51) do not inform that lamp 10 is just going out in the situation that of slowing down, do not need to extinguish processing, therefore finish this process.Be masked as " 1 " (#51 is branch) if lighted, further check extinguish mark be whether " 1 " (#52).Be not " 1 " (the no branch of #52) if extinguish mark, do not inform that in aligning the deceleration of light yellow lamp 10 works extinguish the stage of preparation, therefore finish this process.Be masked as " 1 " (#52 is branch) if extinguished, inform that in aligning the deceleration of light yellow lamp 10 works extinguish the stage of preparation, therefore set and extinguish threshold value (#53), by current deceleration/decel with extinguish threshold value and compare (#54).Now, extinguish threshold value: S2 will use and inform the threshold value using in judgement with lighting: the value of relatively low standard compared with S1, is therefore used the such relational expression (transition diagram) of for example S2=S (S1) to derive S2.
If deceleration/decel: R is not less than and extinguishes threshold value: S2 (the no branch of #54), and regard as not yet to reach and extinguish decision condition, therefore keep intact, finish this process.If deceleration/decel: R is lower than extinguishing threshold value: S2 (#54 is branch), meet the decision condition that extinguishes of relevant deceleration/decel, and therefore further carry out for guaranteeing MIN time meter inspection (#55) of lighting the time.If the time meter time does not arrive (the no branch of #55), regard as and may can't guarantee MIN lighting the time, not extinguishing deceleration and informing lamp 10 and finish this process.If time is up for time meter (#55 is branch), guarantee MIN lighting the time, therefore extinguishing slows down informs lamp 10 (#56).Then, time meter is made zero (#57), " 0 " is set as lighting mark and extinguishes mark (#58), finish this process.
Inform that for deceleration lighting of lamp 10 extinguish control by as described above, in the time producing the deceleration that inform to outside, lighting slows down informs lamp 10, informs lamp 10 not needing to inform to extinguish to slow down while slowing down.In addition, above-mentioned extinguish decision condition by importing, namely extinguish processing, can avoid slowing down and inform that lamp 10 repeatedly lights and extinguish within irrational short period.
