Detailed description of the invention
Sketch illustrates the belt driver of motor vehicles in FIG, represents by reference 100.
The internal combustion engine 110 of motor vehicles has bent axle, and described bent axle is not rotatably connected with transmission of crankshaft wheel 150.Transmission of crankshaft wheel 150 is such as designed as tep reel.
Internal combustion engine 110 by transmission band 120, such as, is connected with the starter-generator 130 of transmission V belt translation by wedge shape rib transmission band, to transmit torque.Transmission band 120 particularly power, and/or shape adaptation be engaged to starter-generator 130 transmission of crankshaft wheel 150 and driving wheel 131 in.Drive 131 is connected un-rotatably with the rotor of starter-generator 130.Internal combustion engine 110 is connected by transmission band 120 and other parts 160, such as fan or cooling medium pump.
Arranging the first controller 115, especially for controlling internal combustion engine 110, design second controller 135 is especially for controlling starter-generator 130.Controller 115 and 135 by fieldbus 170, such as, is connected to each other by CAN transmission data.First controller 115 is particularly provided for implementing the preferred form of implementation of the method according to the invention.It is pointed out that the preferred form of implementation that second controller 135 the most also can be provided for implement the method according to the invention.
It is known that starter-generator both can flexibly run, it is possible to generating ground runs.Therefore, transmission band allows for transmitting torque to both direction.So transmission band to be such as designed as wedge shape rib transmission band.Whether it is motor-driven operation or generator operation according to starting raw device 130, the carrying branch of conversion transmission band 120 and unloaded branch.Additionally, also set up corresponding belt tensioner 140, in order to pre-tensioner transmission band 120.Described belt tensioner 140 such as may be designed as swing type belt tensioner, and described swing type belt tensioner includes such as two swing arm 141a and 141b, and described swing arm is connected to each other especially by spring mechanism 143.The rotary shaft of the two swing arm 141a and 141b is such as with the rotary shaft 132 of the drive 131 of starter-generator 130 on the same line.Other embodiment of swing type belt tensioner or double-arm stretcher also can have the axle the most on the same line of the rotary shaft with starter-generator.Therefore, this rotary shaft 132 of drive 131 is also the rotary shaft of swing type belt tensioner 120 simultaneously.Each swing arm 141a or 141b is connected with regulating wheel 142a or 142b respectively.
Belt driver 100 is analogously shown with Fig. 1 in fig. 2.Illustrate that starter-generator 130, for motor-driven operation, illustrates that it is generator operation in figure 2b in fig. 2 a.
Drive 131 according to Fig. 2 a, such as starter-generator 130 is motor-driven operation, is ω with the rotating speed around rotary shaft 132.By transmission band 120, torque is sent to internal combustion engine 110 from starter-generator 130 in this case.Driving moment M is produced by starter-generator 130m.The band section of the transmission band 120 between drive 131 and transmission of crankshaft wheel 150 forms carrying branch 122 in this case, and the band section between drive 131 and other parts 160 forms unloaded branch 121.
According to Fig. 2 b, drive 131 such as rotates with rotational speed omega in generator operation.By transmission band 120, torque is sent to starter-generator 130 from internal combustion engine 110 in this case.Do not produce driving moment M from starter-generator 130 nowm, but produce braking moment Mg.Compared with motor-driven operation, the position of carrying branch 122 and unloaded branch 121 is exchanged.
Produce which kind of torque according to starter-generator 130 and change swing type belt tensioner 140 and transmission band 120 position.Among these, the arm of swing type belt tensioner 140 rotates towards the direction of carrying branch 122 around rotary shaft 132.
The special characteristic of transmission band 120 particularly its length is the most suitable with the system being made up of internal combustion engine 110, starter-generator 130 and other parts 160.The abrasion of transmission band and elongated meeting cause the function of belt driver 100 to be restricted, such as, cause reducing pre-tensioner, and therefore cause reducing the torque that can transfer.
In order to early identify the structure change beyond the amount allowed of transmission band 120, such as, controller 135 is set for implementing the preferred form of implementation of the method according to the invention, shows the block diagram of described form of implementation Fig. 3 sketch.
In step 201, belt driver 100 is in resting position, internal combustion engine 110 and starter-generator 130 all off-duties.In this case, during swing type belt tensioner 140 does not offset and is in its resting position or in an intermediate position in.Transmission band 120 also is located in its resting position and not skew.
Starting internal combustion engine 110 by starter-generator 130, starter-generator 130 runs in motor-driven operation for this purpose.Starter-generator 130 is made to be in rotational motion in step 202..
According to step 203, as long as second controller 135 detects that starter-generator 130 starts this rotational motion and just determined that the very first time stabs by second controller 135.
By the torque produced in starter-generator 130, swing type belt tensioner 140 and transmission band 120 offset out from their corresponding resting position.Carrying branch shortens and unloaded branch is elongated.In step 204, if carrying branch tensioning obtain enough tight, then internal combustion engine 110 is also among rotational motion.Generally, the first controller 115 detecting this rotational motion, such as, send wheel by monitoring bent axle.According to step 205, the first controller 115 is produced the second timestamp and is notified this stamp to second controller 135 by CAN.Time interval according to step 206, between the starting point of that determine starter-generator 130 by the first and second timestamps in second controller 135 and internal combustion engine 110 rotation.
Particularly when starting internal combustion engine 110 every time by this determination of starter-generator 130 repetition interval, time interval this determines and represents by reference 207.It is thus determined that substantial amounts of time interval, these time intervals such as can be stored in second controller 135.
Analyze these time intervals by each newly determined time interval, and compare with reference value.For this purpose it is proposed, in a step 208 the plenty of time interval of storage is carried out statistical analysis.Particularly carry out time series analysis.The trend of time interval is can determine that by time series analysis.
When analysis result draws: the certain amount of starting process (such as through at least five starting process) through internal combustion engine 110 reaches threshold value in corresponding specific difference between time interval and reference value, then identify the structure change of the amount of the permission exceeding transmission band 120.According to step 209, when the structure recognizing transmission band 120 changes, the most such as, activate the alarm lamp in the instrument panel area of vehicle and/or in fault memorizer, set up failure logging.
Confirmable chart during sketch is shown in the statistical analysis of time interval in the diagram.Here, single time interval Δ t is based respectively on affiliated starting process X and draws, this start-up course correspondingly determines described time interval.Determine that the trend of specific time interval or trend curve 301 are as linear function by time series analysis.
When at corresponding specific time interval Δ t and its quasi-value Δ tRefBetween difference when exceeding threshold value, the most this situation is particularly equivalent to more than the maximum Δ t of the permission of specific trend curve 301max.When trend curve 301 through certain amount of starting process (such as in starting process X1And X2Between) exceed maximum Δ tmaxTime, then identify the structure change of the amount exceeding permission of transmission band.
Illustrating by the mathematical relationship between Fig. 5 time interval and physical dimension to belt driver below, in Figure 5, and Fig. 1 and Fig. 2 analogously sketch is shown in the part starting belt driver during internal combustion engine 110 by starter-generator 130.
Diagram source belt driver in static in fig 5 a, and represent by reference 100a.Swing type belt tensioner 140a and transmission band 120a are respectively in their resting position.Illustrate that starter-generator 130 starts the belt driver after the time interval Δ t after rotational motion in figure 5b, and represent by reference 100b.In this case, swing type belt tensioner 140b offsets, and carries branch and sufficiently shorten, in order that making internal combustion engine 110 be among rotational motion.
Illustrate that swing type belt tensioner is positioned at its resting position (140a) and neutralizes in its position (140b) of corresponding skew in fig. 5 c.Swing type belt tensioner 140b through offseting offset by α deviation angle relative to its resting position 140a.
The inertia J particularly starting raw device 130 reacts on the skew of swing type belt tensioner 140.The torque M of starter-generator 130, its inertia J and starter-generator 130 or its change of rotational speed omega of drive 131 be in following relation to each other:
。
That draw starter-generator 130 from following relational expression or its corner of process of drive 131:
。
Time interval Δ t between the starting point of that draw starter-generator 130 from following formula and internal combustion engine 110 rotation:
。
erfRepresent for starting the corner required for internal combustion engine 110.The offset angle required by belt tensioner 140 is specified especially for the starting torque required for starting internal combustion engine 110erf, the most described deviation angle again with the corner of starter-generator 130Proportional.
Such as it is positioned among low millisecond (ms) region for reference value new, untight transmission band time interval Δ t, such as, may be about 16 milliseconds.Structure change beyond the amount of the permission of transmission band causes less pre-tensioner, and particularly results in the change of the resting position of swing type belt tensioner.Which thereby enhance required offset angleerf, and increase time interval Δ t.
