Fig. 5 is the position correction of the weighted sum clutch actuator of change in a kind of mode of execution medium temperature by method of the present invention.
Embodiment
By accompanying drawing, a kind of mode of execution by method of the present invention is made an explanation below.The major effect of the pressure surge in the clutch hydraulic pressure section of Motor Vehicle is based on the fluctuation of the change of the medium temperature of described clutch hydraulic pressure section.These changes of medium temperature are checked by a kind of algorithm by temperature model, and for the position correction of clutch actuator.Substantially thereby saving the pressure transducer in described clutch fluid pressing system.Eliminate the ADC input end and sensor service voltage that use in described controller equally for this reason.
The temperature model of hydraulic fluid is based upon on two kinds of temperature impacts substantially.First, by depend on the engine speed of the internal-combustion engine of described Motor Vehicle, heating coefficient be used for describing described temperature model; Secondly, also use the coefficient depending on the cooling of motor vehicle speed for this reason.Hydraulic medium is connected with described when clutch disconnects, namely separates (Fig. 1) from described automatic deflation hole to the connection of compensation vessel in batch scheme (Serien-Konzept).Show the automatic deflation hole 10 of opening in fig 1 a and show the automatic deflation hole 11 of closedown in Figure 1b.In order to open and close described automatic deflation hole, described piston 12 is moved.Due to temperature effect, produce Volume Changes by the coefficient of described medium temperature.Position attachment relationship can not be produced again thus between actuator position and the position of slave cylinder.By the understanding of the change to the medium temperature in described hydraulic pressure section, can by the coefficient of whole hydraulic pressure quality and medium temperature for described clutch actuator carries out position correction.
Temperature algorithm is activated shown in figure 2, if the change of each unit of time medium temperature after the time given in advance lower than temperature derivative threshold value given in advance.By about the motor merit 14 in past and the characterisitic family 13 of motor vehicle speed 15 as used herein, select the initial medium temperature 16 of the change 17 for calculation medium temperature.Calculate described experienced engine power 14 at this, its mode is: the mean value forming the engine power of 20 seconds in the past.Described characterisitic family because of but a kind of chart of three-dimensional, this chart is assigned with initial medium temperature 16 for the motor vehicle speed 15 that often kind of engine power experienced 14 and period travel.Then by described initial medium temperature 16, described motor vehicle speed 15, described engine speed 18 and described medium temperature change 17 and calculate the current change 17 of described medium temperature by the coefficient 19a of described heating and the coefficient 19b of cooling.For the change 17 of described medium temperature this calculating with regular, lower than the time period repetition of time threshold given in advance.Described coefficient 19a, 19b obtain from measured value as the medium temperature change of each unit of time.
Fig. 3 is to scheme the characteristic curve of the coefficient of the cooling indicated for described Motor Vehicle.At this, the abscissa of described chart shows in the change of the medium temperature of each unit of time dT/dt of kelvin scale per second, and show per hour in the motor vehicle speed v of km on the vertical scale.Be weighted by the change calculated of absolute medium temperature to described medium temperature.The decay of described cooling is such as realized thus with identical ambient temperature and medium temperature.
In order to estimate that described absolute medium temperature utilizes the temperature efficiency of described actuator.This point is shown in Figure 4.Described clutch actuator was disconnected before the coast period that Motor Vehicle carries out with constant speed.In the process disconnected, integration is carried out to the power consumpiton of described actuator.For the actuator's merit so detected or energy 20, between energy 20 and absolute medium temperature, there is coherence.By characterisitic family 22, this conversion from energy to medium temperature is preserved in a control unit.When sliding beginning, new medium temperature 21 is estimated thus, and averaged by former absolute medium temperature 25.Estimated medium temperature 21 and former absolute medium temperature 25 are added for this reason, and half-and-half divide described summation equally 23.Obtain the current numerical value of described absolute medium temperature 25 thus.From described ambient temperature 26 and absolute medium temperature 25, calculate 28 subsequently and determine temperature difference 27 thus.By this temperature difference 27 divided by 29 numerals 20, for obtaining weighting factor 30 about described ambient temperature 26 from described absolute medium temperature 25.Just describedly to be averaging and the result of weighting procedure is described weighting factor 30 thus.For the initialization of the estimation procedure of described medium temperature 21, there are two kinds of feasible programs available: the difference for described engine temperature and described ambient temperature is less than this situation of temperature threshold given in advance, make described absolute medium temperature initialization by described ambient temperature.Further calculating is then undertaken by the mode be averaging by last estimated medium temperature value 23.At least differ this situation of described temperature threshold given in advance for described engine temperature and described ambient temperature, the initialization of temperature is carried out when sliding beginning after disconnecting described clutch first.
Again generally illustrates described whole algorithm in Figure 5.The medium temperature 21 estimated by 31 is determined from described actuator energy 20 and described ambient temperature 26.Determine described weighting factor 30 thus.This process obtains detailed description when discussing Fig. 4.Weighting factor 30 is obtained about described ambient temperature 26 thus from described absolute medium temperature 25.When discussing Fig. 2, from described engine power 14, described motor vehicle speed 15 and described engine speed 18, determine the change 17 of described medium temperature as already described by the change of described temperature algorithm 32.Subsequently described weighting factor 30 is multiplied 33 with the change 17 of described medium temperature, and is weighted with the change of this weighting factor to described medium temperature thus, that is produce the change 34 through weighting of described medium temperature.Temperature difference between absolute medium temperature and described ambient temperature can affect the cooling (see Fig. 5) of described clutch hydraulic pressure section under the support linearly or in characterisitic family at this.Finally, from the change calculated obtaining described medium temperature through the change 34 of weighting of described medium temperature.By the size of the hydraulic pressure quality in described clutch fluid pressing system and the size of hydraulic buckling coefficient 35, by being multiplied 36 with the change 34 through weighting of described medium temperature, the change of the amount 37 in described clutch fluid pressing system can be calculated.By referring to this mode of actuator's basal plane 39 described in 38, can correct the position 40 of described clutch actuator thus.Specifically, this by the change of described amount 37 divided by described actuator basal plane 39, and obtain the difference (Delta) of the position 40 of described clutch actuator thus.By position 40, this difference taken in the change 17 of medium temperature of described clutch actuator, the position of described clutch actuator is corrected.The effect produced the change 17 due to described medium temperature by this correction is compensated.When controlled clutch, carried out the rated moment 41 of described clutch given in advance by driver.By characteristic curve 42, this rated moment 41 of described clutch is converted to the nominal position 43 of described clutch actuator.Carry out correction 44, for finally obtaining the position 45 through overcorrect of described clutch actuator by this nominal position 43 of difference to described clutch actuator of the position 40 of described clutch actuator now.At this, constantly the position 40 of described clutch actuator is not corrected, but only just load described correction process when described clutch closes.Avoid larger actuator's load thus.If described clutch closes again, the medium so expanded just can be balanced with compensation vessel and described algorithm is resetted.Can abandon thus for described clutch actuator position 40, compensation on the basis that is based upon pressure transducer.
