Embodiment
Below, embodiments of the present invention are described.
Fig. 1 represents the gear detection device 1 involved by embodiments of the present invention, and this gear detection device 1 comprises the suppression switch (inhibitor switch) 10 worked by the operation of speed change lever (not shown), the controller 20 inputted from the first Out let 11 be arranged on this switch 10 to the on/off signal that the 4th Out let 14 exports respectively in the future.
And, described controller 20 judges the gear residing for speed change lever according to the on-off Combinative pattern of described four on/off signals, and in order to carry out controlling with the pattern corresponding with the gear in automatic transmission 30, the gear judged is sent to this automatic transmission 30, in addition, in order to the display unit 40 on driver's seat being arranged on this vehicle etc. shows selected gear and this display unit 40 sent to the gear judged.
Herein, in this mode of execution, as representing the gear of MLP and the intervening gears that is provided with between the usual gear of these alternatives as driver of P, R, N, D and adjacent usual gear, now, usual gear arranges with described order, therefore intervening gears has the PR shelves between P shelves and R shelves, the RN shelves between R shelves and N shelves and the ND shelves between N shelves and D shelves, detects above seven gears in this mode of execution.
Relevant these usual gear and intervening gears, as shown in Figure 2, the on-off style of first to fourth Out let is defined, and nine kinds of abnormal styles beyond this are on-off combination as shown in Figure 3.
In this embodiment, the normal style of each gear shown in Fig. 2 is defined with following regularity.
First, in seven gear row from P shelves to D shelves, define in the mode differing in adjacent style each on-off each other.
In addition, it is two that usual gear P, R, N, D are set to connection, is broken as two, and it is one or three that intervening gears PR, RN, ND are set to connection, is broken as three or one.
Thus, be the normal style that only on-off state is different compared with the abnormal style of normal style meets the usual gear of Fig. 2 with connecting in the abnormal style shown in Fig. 3.Such as, in Fig. 3, first Out let of second is separately the abnormal style of connection from left to right, different from the on-off of the usual gear N of the normal style of Fig. 2 only the second Out let, and different from the on-off of the usual gear D of the normal style of Fig. 2 only the 4th Out let.In addition, in Fig. 3, second Out let of the 3rd is separately the abnormal style of connection from left to right, different from the on-off of the usual gear R of the normal style of Fig. 2 only the 3rd Out let, different from the on-off of the usual gear N of the normal style of Fig. 2 only the first Out let in addition.In the same manner, in Fig. 3, the 4th Out let of the 4th is separately the abnormal style of connection from left to right, different from the on-off of the usual gear D of the normal style of Fig. 2 only the first Out let, different from the on-off of the usual gear P of the normal style of Fig. 2 only the 3rd Out let in addition.
In addition, with connect in the abnormal style shown in Fig. 3 be compared with the abnormal style of three time normal style that only on-off state is different meet the normal style of the usual gear of Fig. 2.Such as, the abnormal style that is off separately of first Out let of second from right to left in Fig. 3, different from the on-off of the usual gear P of the normal style of Fig. 2 only the second Out let, and different from the on-off of the usual gear R of normal style only the 4th Out let.
That is, with connect in the abnormal style shown in Fig. 3 be one or three abnormal style compared with time normal style that only an on-off state is different, all meet the normal style of the usual gear (travelling shelves R, D and non-traveling shelves P, N) of Fig. 2.
In addition, the normal style that only on-off state is different compared with the abnormal style connected as zero time meets the normal style of intervening gears.Such as, the abnormal style that is all off to the 4th Out let of first Out let of first from left to right in Fig. 3 is different from the on-off of the intervening gears PR of the normal style of Fig. 2 only the 3rd Out let.
In the same manner, with connect be compared with the abnormal style of two time normal style that only on-off state is different meet the normal style of intervening gears.Such as, in Fig. 3, first Out let of the 5th and the 3rd Out let are the abnormal style connected from left to right, different from the on-off of the intervening gears PR of the normal style of Fig. 2 only the first Out let, in addition, different from the on-off of the intervening gears RN of normal style only the second Out let.In Fig. 3, sextus second Out let and the 4th Out let are the abnormal style connected from left to right, different from the on-off of the intervening gears ND of the normal style of Fig. 2 only the first Out let.
In the same manner, with connect be compared with the abnormal style of four time normal style that only on-off state is different meet the normal style of intervening gears.Such as, in Fig. 3, first Out let of first is the abnormal style of connection to the 4th Out let from right to left, different from the on-off of intervening gears RN and ND of the normal style of a Fig. 2 only Out let.
That is, the normal style that only on-off state is different compared with the abnormal style connected in the abnormal style shown in Fig. 3 as zero, two or four time all meets the normal style of the intervening gears (PR, RN, ND) of Fig. 2.
In addition, the style of the usual gear in the normal style shown in Fig. 2, defines to connect by the order two of P → R → N → D the mode offset one by one from the 4th Out let side direction first Out let side.
Thus, at not adjacent according to the sequence usual gear, the R shelves being namely traveling shelves and D shelves and between the P shelves being non-traveling shelves and N shelves, be respectively that the connecting and disconnecting of two are all exchanged, thus the on-off of all terminals is different.On the R shelves as traveling shelves, the first, the 4th Out let is off, and second, third Out let is for connecting, and on D shelves, the first, the 4th Out let is for connecting, and second, third Out let is off.In addition, on the P shelves as non-traveling shelves, first, second Out let is off, and the 3rd, the 4th Out let is for connecting, and on N shelves, first, second Out let is for connecting, and the 3rd, the 4th Out let is off.
Thus, when compared with arbitrary abnormal style time, on-off state is when only a different normal style meets the style of two usual gears (two in P, R, N, D), and the usual gear one of these two of meeting is decided to be the combination travelling shelves (R, D) and non-traveling shelves (P, N).
Above result, is documented in the hurdle of " judging candidate's gear " of this figure from the gear of kind of the abnormal style of nine shown in Fig. 3 only normal style that on-off is different.
Below, control to be described to the judgement of the gear realized by described controller 20.
This control is carried out according to the flow chart shown in Fig. 4, first, in step S1, read in the on/off signal from suppressing the first Out let 11 of switch 10 to export to the 4th Out let 14, in step S2, whether unanimously with certain one in the normal style shown in Fig. 2 judge that namely the on-off Combinative pattern shown in these signals exports style.
And, when there is consistent normal style, in step S3, assert the gear of the gear of this normal style residing for speed change lever (hereinafter referred to as " actual-gear ").
On the other hand, when the arbitrary normal style shown in described output style and Fig. 2 is all inconsistent, namely when exporting style for certain one in kind of the abnormal style of nine shown in Fig. 3, in step S4, to judge and this abnormal style gear of normal style that only on-off is different, the judgement candidate gear namely shown in Fig. 3 only have one still to have two.
Such as, when the abnormal style that all Out lets of Fig. 3 left end are off, the normal style that only on-off is different is therewith only have a style connected, and distinguishes that the person of meeting is only the style of PR shelves according to Fig. 2.In addition, when only first Out let of second is the abnormal style connected from left to right, the normal style that only on-off is different is therewith have two styles connected, distinguish that the person of meeting is for N shelves and D shelves according to Fig. 2, judge candidate's gear as one at the former time during output abnormality style, and when the latter be two.
And, determined by this acts of determination judge candidate's gear as one time, next perform step S5, judge to be set to judge that the gear of candidate is as actual-gear.
On the other hand, in described step S4, determine to have two from the abnormal style the exported normal style that only on-off is different, namely judge that candidate's gear has two time, next in step s 6, judge that these two judge candidate's gear whether as intervening gears.
Now, as mentioned above, two judging that candidate's gear is intervening gears or is usual gear, when being intervening gears, judging that actual-gear is as N shelves in the step s 7.
In addition, when being usual gear, as mentioned above, one is for travelling shelves, and another one is non-traveling shelves, therefore in step s 8, judges to travel shelves as actual-gear.Such as, the abnormal style exported be in Fig. 3 from left to right second style time, meet on-off only a different normal style judge that candidate's gear is as N shelves and D shelves, now, judge that D shelves as traveling shelves are as actual-gear.
Above, when exporting in the connection fault suppressing the first Out let 11 of switch 10 to certain one in the 4th Out let 14 to produce to cause because of short circuit etc. or the open failure that causes because of broken string etc. from the normal style abnormal style that only on-off is different, judge the actual-gear residing for speed change lever according to the relation of abnormal style and normal style.
In addition, be difficult to the imagination can produce described connection fault and open failure at multiple Out let simultaneously, in addition, the abnormal style that two on-offs are different is had from certain normal style, become style normal from other consistent or have with other normal styles the abnormal style that an on-off is different, therefore do not consider that exporting style has from normal style the situation that two on-offs are different.
And, first, from the abnormal style the exported normal style that only on-off is different judge candidate's gear as one time, judge the actual-gear of this gear residing for speed change lever, the gear thus residing for speed change lever can become the shift pattern of the script wish following operator with higher probability.
In addition, when judging candidate's gear as two, when being intervening gears for these two, think that the gear residing for speed change lever is N shelves.
Now, it is generally acknowledged that actual gear is a certain intervening gears, but the gear because of intervening gears not for determining a certain traveling control mode, even if so be judged to be that neutral gear also can not cause actual damage to traveling control, drawback compared with the control under usual gear is thereafter hindered to reduce with being defined as intervening gears by mistake.
In addition, when judging that candidate gear has two, when these two gears be the traveling shelves of usual gear with non-traveling shelves time, judge that actual-gear residing for speed change lever is as travelling shelves.
Now, if the position of the speed change lever of reality is for travelling shelves, then correctly can carries out gear judgement, can control with the pattern following driver's wish.
On the other hand, if the position of the speed change lever of reality is non-traveling shelves, then gear decision error, if but the position of speed change lever is in non-traveling shelves, vehicle also can not travel, with in the position of speed change lever be but be judged to be non-traveling shelves when travelling shelves situation compared with, the danger that the control of the pattern desired by driver counteracts is reduced, thus can actual damage be suppressed.
In addition, the example of the output style according to Fig. 2, Fig. 3, even if it is contemplated that when the output style from suppression switch 10 is any one in normal style, if exporting on-off compared with normal style originally because of arbitrary Out let fault is contrary signal, the result situation that but style normal with other is consistent, now, as judge the actual-gear of gear residing for speed change lever of normal style that export, then form erroneous judgement.
Such as, when when first, second Out let of output is off, the 3rd, the 4th Out let is the style connected, as shown in Figure 2, due to be to P shelves definition normal style and judge that actual-gear is as P shelves, although but be actually and cause the position of speed change lever to be the situation that PR shelves export the normal style of P shelves because of the connection fault of the 4th Out let, below, the flow chart according to Fig. 5 is described the control example had for action now.
The step S11 to S18 of this flow chart is identical with the step S1 to S8 of the flow chart of Fig. 4, but when judging in step s 12 to export style as normal style, judges in the step s 21 to identify F whether as " 1 ".
This mark F such as when ato unit or to resetting to " 0 " when suppressing the fault of switch 10 to carry out repairing etc., thereafter, only otherwise output abnormality style just remains " 0 ".Thus, when non-output abnormality style, in step s 13, the judgement of carrying out actual-gear when exporting normal style identical with the step S3 of the flow chart of Fig. 4 controls.
In addition, when judging to export style as abnormal style in described step S12, then according to step S14 to S18, the judgement of actual-gear when carrying out output abnormality style identical with the step S4 to S8 of the flow chart of Fig. 4 controls.
But, in this control example, when judging to export abnormal style in described step S12, in step S22, set is established to described mark F.Therefore, when operating thereafter speed change lever, when exporting normal style from suppression switch 10, after step S21, perform step S23 to S25 from described step S12.
Now, in this control example, judge that the mode of candidate's gear sets to be set to by the gear of the gear of the normal style exported and the normal style that has on-off different from this style.
In addition, as mentioned above, from P shelves to the normal style of seven gears of D shelves to set in the adjacent style mode that on-off differs to each other, therefore as shown in Figure 6, judge candidate gear become exported normal style gear and with adjacent to its gear, when exporting the style of the P shelves at the two ends being positioned at described seven gears row and D shelves, judge that candidate's gear is as two, and when exporting the style of the gear beyond this, judge that candidate's gear is as three.
And, in step S23, judge whether there are traveling shelves in the judgement candidate gear extracted in the above described manner, and when there are traveling shelves, in step s 24 which, judge the actual-gear of these traveling shelves residing for speed change lever, and when there are not traveling shelves, in step s 25 N shelves are set to the actual-gear residing for speed change lever.
Such as, as shown in Fig. 2, Fig. 6, be judged to be D shelves when output style is the normal style of D shelves or ND shelves, be judged to be R shelves when output style is the normal style of R shelves or PR shelves or RN shelves, be judged to be N shelves when output style is the normal style of P shelves or N shelves.
Thus, once after exporting abnormal style, even if when exporting normal style, also suitably can judge the actual-gear residing for speed change lever identically with during the above-mentioned abnormal style of output.
In addition, the style of each gear in above mode of execution is defined as an example, even if be other definition examples, also can implement the present invention.
The gear detection device of automatic transmission of the present invention, the signal of the operation corresponding to speed change lever is exported from multiple Out let, and detect the gear residing for described speed change lever according to the Combinative pattern of described signal, gear residing for described speed change lever of the Combinative pattern of described signal and changing, it is characterized in that: described Combinative pattern is made up of normal style and abnormal style, described normal style comprises usual gear and intervening gears, described usual gear is by travelling shelves and non-traveling shelves are formed, described traveling shelves are by retreating shelves and forward gears is formed, described non-traveling shelves are made up of park and neutral gear, described intervening gears is the gear between adjacent described usual gear, described gear detection device comprises: the first decision mechanism, when described Combinative pattern meets any gear of described normal style, judge the gear of gear residing for described speed change lever meeting this style, second decision mechanism, described Combinative pattern be any gear not meeting described normal style abnormal style and from the gear of the described normal style style that only signal is different time, judge the gear of gear residing for described speed change lever meeting this normal style, be described abnormal style at described Combinative pattern and be described retrogressing shelves from the gear of this abnormal style only described normal style that signal is different, described forward gears, during in described park and described neutral gear one, described second decision mechanism judges the gear of gear residing for described speed change lever meeting this normal style.
According to said structure, when exporting the abnormal style of any one in the normal style all not meeting and define with regard to each gear from multiple Out let, judge to meet the gear of gear residing for speed change lever from the style of this output only normal style that signal is different, therefore also can determine gear when output abnormality style, thus need not travelling be sacrificed and can continue to travel.
Now, when being in described retrogressing shelves, described forward gears, described park and described neutral gear one from the gear of the described abnormal style only normal style that signal is different, judge the gear of gear residing for speed change lever meeting this normal style, therefore can obtain higher judgement precision (probability that can realize the shift pattern that operator wishes originally increases).
It is preferable that in gear detection device of the present invention, be described abnormal style at described Combinative pattern and have two from the gear of this abnormal style only described normal style that signal is different and these two gears be combined as described forward gears and described neutral gear or described forward gears and described park time, described second decision mechanism judges the gear of described forward gears residing for described speed change lever; Be described abnormal style at described Combinative pattern and have two from the gear of this abnormal style only described normal style that signal is different and these two gears be combined as described retrogressing shelves and described neutral gear or described retrogressing shelves and described park time, described second decision mechanism judges the gear of described retrogressing shelves residing for described speed change lever.
According to this structure, two are had from the exported abnormal style normal style that only signal is different, and the gear meeting these normal styles is when travelling shelves and non-traveling shelves, judge the gear of these traveling shelves residing for speed change lever, therefore be when travelling shelves in the position of the speed change lever of reality, correctly can carry out gear judgement, thus the wish following driver travels.
In addition, when the position of speed change lever is non-traveling shelves, even if be judged to travel shelves, as long as speed change lever be now in non-traveling shelves then vehicle can not travel, compared with the situation being judged to be non-traveling shelves when being in travelling shelves with the position of speed change lever, the possibility counteracted the control of the pattern desired by driver is few, thus can suppress actual damage.
It is preferable that in gear detection device of the present invention, be described abnormal style at described Combinative pattern and have two from the gear of this abnormal style only described normal style that signal is different and the gear meeting these normal styles is described intervening gears time, described second decision mechanism judges that gear residing for described speed change lever is as neutral gear.
According to this structure, two are had from the exported abnormal style normal style that only signal is different, and the gear meeting these normal styles is when being intervening gears, judge that gear residing for speed change lever is as neutral gear, even if therefore the gear of reality is arbitrary intervening gears, all actual damage can not be caused.
Namely, intervening gears only operation speed change lever process in process gear and be not the gear determining arbitrary traveling control mode, even if be therefore judged to be that neutral gear also can not cause actual damage to traveling control, drawback is less compared with the situation of the control under the usual gear hindered because determining intervening gears by mistake thereafter.
