- the electronic control unit 1 comprises first means 10 which determine the target value for the torque to be output by the drive unit 5.
- the first means 10 are connected to the control element 90 on the input side via the fifth connecting line 88.
- Output lines of the first means 10 represent the lines 101 and 102 for controlling the transmission 65 and the converter 20 of the transmission unit 45 as well as a line 110 which leads to a first connection point 115.
- the first is on the output side
- node 115 is connected to the actuating device 105 via the output line 100.
- the setpoint for the torque to be output by the drive unit 5 transmitted on the line 110 represents a setpoint for the so-called indicated engine torque, in other words, for the engine combustion process
- the first link point 115 is thus part of second means 15, which is the setpoint for the drive unit
- Means 15 correct the torque to be set as a function of the loss moments of the drive unit 5 and / or of the torque requirement of the additional consumers which load the drive unit 5.
- the second means 15 additionally include torque detection and evaluation with
- the torque detection and evaluation means 120 differentiate the determined loss moments of the drive unit 5
- the second loss moments and / or the second torque requirement are supplied to a second connection point 130 via a line 125.
- the second connection point 130 is connected on the output side to the first connection point 115 via a line 135.
- the first loss moments and / or the first torque requirement are fed via a line 140 to a third connection point 145, which is connected on the output side to the second connection point 130 via a line 150.
- an idle speed controller 25 is provided, to which the speed of the drive unit 5 is supplied via the first connecting line 76 and to an idle speed setpoint n_set via a line 155, which is calculated in a calculation unit 160 from operating variables of the drive unit 5 and / or the vehicle 35 which are transmitted via the lines 91 to 93 are fed and detected by the measuring devices 95 to 97 is formed.
- An output line 165 of the idle speed controller 25 is also fed to the second node 130.
- the idle speed setpoint n_soll is also determined in the manner known from DE 43 04 779 AI, which is also part of the disclosure in this regard.
- the idle speed setpoint n_soll is also supplied by the calculation unit 160 to a fourth node 175 on a further output line 170.
- Junction point 175 is also the turbine speed above the second connecting line 81 is supplied.
- an output line 180 leads to third means 185 for realizing a characteristic curve 30.
- the third means 185 are connected to the third connection point 145 via a line 190.
- the input variables are added.
- the input variables are multiplied.
- the input variables are divided. The idle speed is
- the second means 15 already take into account the loads on the drive unit 5 due to the loss moments of the drive unit 5 and / or the torque requirement of additional auxiliary units, so that
- the third means 185 can be dispensed with and the output variable of the fourth connection point 175 can be routed directly to the third connection point 145.
- the third means 185 are therefore shown in dashed lines in FIG.
- the first lost torques and / or the first torque demand are included with a factor F> 1. This causes an increased pilot control of the losses and leads to an increase in the engine speed n_mot in the direction of the idle speed solenoid value n_soll.
- the weighted first loss moments and / or the weighted first torque requirement are supplied to the second connection point 130 via the line 150.
- the second loss moments and / or the second torque requirement are calculated without multiplication by a factor, ie with the weight device 1 fully included and fed via line 125 to the second node 130.
- the idle torque required by the idle speed controller 25 is supplied via line 165 in the second node 130.
- the idle torque demanded by the idle speed controller 25 the first loss moments weighted by the factor F and / or the first torque demand weighted by the factor F and the second loss moments and / or the second torque demand are added.
- the sum results in a required total idling torque, which takes into account the loads on the drive unit 5, in particular due to the loss moments of the drive unit 5 and / or the torque requirement of auxiliary units.
- the required total idling torque is fed via line 135 to the first connection point 115 and added there with the determined target value for the torque to be output at the drive unit 5.
- the corrected setpoint value resulting from this addition for the torque to be output by the drive unit 5 is output via the output line 100 to the actuating device 105 for realizing this corrected setpoint value.
- the electronic control unit 1 with the first loss moments of the drive unit 5 and / or the first torque requirement of the auxiliary units, only those loss moments of the drive unit 5 and / or only such torque requirement of the auxiliary units are weighted with the factor F, the chronological course of which during operation of the drive unit 5 or the ancillary units are free of jumps.
- the error made conscious by this weighting in the inclusion of the first loss moments and / or the first torque requirement in the required total idling torque is accepted in favor of the self-stabilization of the drive unit 5.
- the second loss moments of the drive unit 5 and / or the second torque requirement of the auxiliary units has a time course during operation of the drive unit 5 or the auxiliary units, which is subject to jump, in particular during switching operations.
- a weighting of the second loss moments and / or the second torque requirement with a factor not equal to 1 would increase the jump for F> 1 or underestimate the jump for F ⁇ in the event of a jump in the course of the second loss moments and / or the second torque requirement 1 and could lead to an unexpected change in the torque on the drive unit 5 by the driver, especially if the driver does not make any change in the accelerator pedal 90 and therefore does not expect any change in torque. This would reduce driver comfort. Therefore, the second loss moments and / or the second torque requirement are unweighted, that is to say taken into account with the weighting 1 in the addition in the second connection point 130.
- the group of the second loss moments includes, for example, loss moments which occur when switching from high to stratified charge operation in a drive unit 5 comprising a gasoline engine with direct injection, that is to say, for example, in gasoline direct injection engines.
- a sudden change in these moments of loss is primarily due to a change in the gas exchange work.
- the group of second loss moments also includes loss moments which occur when individual cylinders and / or individual valves of drive unit 5 are switched off.
- loss moments which occur when individual cylinders and / or individual valves of drive unit 5 are switched off.
- the energy for controlling the valves is provided by a generator, the torque loss of which is directly dependent on
- the gas exchange work when one or more valves are switched off, the gas exchange work also changes, as a result of which the sum of the changing loss moments is large and corresponding jumps can occur over the course of these loss moments.
- the group of the first loss moments and / or the first torque requirement includes all those loss moments of the
- First loss Moments can be, for example, converter losses in converter 20 and possibly associated friction power.
- the total loss moments result from the sum of the 5 first loss moments and the second loss moments.
- the total torque requirement of the auxiliary units results from the sum of the first torque requirement and the second torque requirement.
- the third means 185 which implement the characteristic curve 30, can optionally be provided, as shown in FIG. 2.
- the abscissa is the
- a corrected factor Y is assigned to each factor F> 0 via the characteristic curve 30.
- the course of the characteristic curve 30 is constant in order to prevent jumps and thus an unwanted change in torque for the driver.
- the ratio of Y to F for each F is greater than
- the value going beyond the basic value with a change in the jump is included unweighted, which means that the share of moments in the total loss torque that are not weighted is smaller, and thus the self-stabilization is increased.
- the value going beyond the basic value with a change in the jump then belongs to the group of the second loss moments of the drive unit 5 and / or the second torque requirement of the additional consumers which put a strain on the drive unit 5.
- the electronic control unit 1 By separating the loss moments of the drive unit 5 and / or the torque requirement of auxiliary units into the first loss moments and / or the first torque requirement on the one hand and the second loss moments and / or the second torque requirement on the other hand, the electronic control unit 1 according to the invention allows the drive unit 5 to self-stabilize by weighting the first loss moments and / or the first torque requirement.
- the second loss moments and / or the second torque requirement is correctly included in the required total idling torque, particularly in the event of a sudden change in the course of time and in the absolute amount of the jump.
- the described electronic control unit 1 also enables the stabilization of the Drive unit 5 in the idle case, for example when the accelerator pedal 90 is not operated and thus no torque is requested by the driver and no gear is engaged.
- the required total idling torque which is fed to the first connection point 115 via the line 135, then also corresponds to the setpoint value to be set by the adjusting device 105 for the torque to be output by the drive unit 5.
- correct pre-control of the loss moments of the drive unit 5 and / or the torque requirement of the auxiliary units is also achieved in the idle case, without any jumps in the time course of the second loss moments and / or the second torque requirement during operation of the drive unit 5 or the auxiliary units The quality of the associated switching process and thus the driving comfort. Jumps in the time course of the second loss moments and / or the second torque requirement are taken into account without distortion in order to determine the required total idling torque, so that there is no change in torque unexpected by the driver.
