Definitions
- the present invention relates to a method for controlling and / or regulating an automated clutch and / or an automated transmission of a vehicle, in which a clutch target torque is determined by means of an electronic clutch management (EKM), as well as a device for control and such a transmission.
- EKM electronic clutch management
- Automated clutches and / or automated transmissions are known from vehicle technology, thereby enabling automation of the drive train of a vehicle, in particular a motor vehicle.
- An electronic clutch management system automates the engagement process when the gearshift is required.
- Coupling management is subject to increased demands, particularly when starting off. For example, the driver must take into account a certain degree of influence and also changed operating conditions, such as. B. increasing engine torque in turbo engines or clutch properties are taken into account.
- the invention has for its object to provide a method for controlling and / or regulating an automated clutch and / or an automated transmission, in which the starting functionality, in particular of the electronic clutch management, is improved.
- the electronic clutch management system performs a starting function as a function of predetermined input sizes is determined with the target clutch torque as an output variable, which is then to be set on the clutch of the vehicle.
- the starting speed can be determined to a greater extent by a driver's request.
- the starting functionality of the electronic clutch management is expanded in such a way that in particular a defined engine speed can be set during the starting process. This enables improved reproducibility of approaches in changing operating conditions.
- the desired clutch torque can be determined by the starting function as a function of at least one of the following input variables, such as, for. B. accelerator pedal angle, engine speed, transmission input speed and / or engine torque can be determined.
- the start-up function is essentially divided into two phases with the aid of a factor calculation.
- further phases it is also possible for further phases to be provided in order to further optimize the starting process for a vehicle.
- the engine speed essentially follows a starting solid speed in order to regulate the starting speed.
- the engine speed and the gearbox input speed must be adjusted in order to synchronize them. This avoids a sharp switchover between the phases and, depending on a so-called speed ratio, which is defined as the quotient of the transmission input speed and engine speed, enables the two phases to be blended continuously during the starting process.
- An advantageous embodiment of the invention provides that a torque contribution is first determined according to a global control in order to calculate the desired clutch torque as an output variable. For this, e.g. B. Shares can be determined as functions of the transmission input speed and / or the engine speed.
- the use of a portion dependent on engine torque is also possible.
- the portion that is dependent on the engine torque is suitably weighted by the speed ratio, so that its full effectiveness is achieved precisely when the synchronization point on the clutch is reached.
- further shares are used in determining the starting function.
- the speed ratio e.g. B. if the value of the speed ratio (SR) is approximately in the range of SR ⁇ 0.5 to 0.7, a regulation of the starting target speed is in the foreground. It is possible that the starting speed over a suitable, for. B. monotonically increasing characteristic curve is determined depending on the accelerator pedal angle. Of course, it is also possible that a characteristic curve of any other design is used.
- the determined starting speed is, for example, low-pass filtered, preferred wise with a PT1 link. It is also conceivable that other filter elements can be used.
- the filter used is initialized by means of the engine speed, in particular if the engine speed in neutral is essentially an idling speed, e.g. B. exceeds values that are about 500 revolutions per minute.
- the initialization can also be done • with smaller or larger values.
- the difference f ⁇ (SR) * (n_Anf-n_mot) weighted by the speed ratio when calculating the factors can, for. B. can be implemented via a PI controller in a contribution to the target clutch torque.
- the PI controller can have the factor KP1 of the proportional element and the factor KI1 of the integrator as parameters. Of course, another controller and / or other parameters can also be used.
- a PI controller can also be used, the input variable of which, for. B. f2 (SR) * (n_mot-n_get).
- the PI controller preferably has the factor KP2 of the proportional element and the factor KI2 of the integrator as parameters.
- other controllers and / or parameters can be used.
- a further development of the invention provides that the I components of both regulations are preferably implemented by the same integrator. This advantageously reduces the complexity of the circuit used. It can be provided that an additional integrator is used for the existing integrator, the z.
- the additional integrator can, for example, have a smaller gain KI3 in order to prevent permanent slippage at the clutch, e.g. B. counteract due to ramp-shaped disturbances, such as a continuously increasing engine torque. It is conceivable that further integrators can also be used, wherein a different circuit configuration can also be provided, and larger or smaller amplifications can be used.
- the target clutch torque determined as an output variable is limited.
- the target clutch torque (M_Rsoll) can be limited by the condition M_Rsoll> 0.
- the integrator used and / or the optionally separated integrators can be subjected to a suitable measure to avoid a so-called wind-up. This can e.g. B. can be achieved by calculating back to a corresponding I torque component (M_l) after limiting the desired clutch torque.
- M_Glob global control
- M_D damping torque component
- M_l M_Rsoll_blimited - M_Glob - M_D + M_P1 + M_P2 with
- M_P1 P torque component of the PI controller in the first phase
- M_P2 P torque component of the PI controller in the second phase
- a further method variant according to the invention can provide that a damping component is included in the determination of the starting function.
- This damping component can be processed both in the first phase, ie when adjusting the starting speed, and in the second phase of factor calculation, ie when synchronizing or reducing slip.
- the use of the damping component can advantageously make a major change, e.g. B. the engine speed, prevent.
- the damping component is preferably applied to the difference between engine speed and transmission input speed.
- Another development of the invention provides that when determining the desired clutch torque by the starting function z. B. the transmission input speed and / or engine speed dependent portion is dispensed with. Any other proportions can of course be reduced or omitted in order to further optimize the overall determination of the starting function in the method according to the invention.
- this throttle-valve-dependent part is used both alone and in connection with the parts already mentioned for determining the starting function.
- the throttle valve-dependent portion z. B With increasing throttle valve angle, the desired clutch torque is reduced in order to increase the starting speed and to prevent almost identical engine speeds from occurring during the starting process over a larger load range. lie.
- the throttle valve-dependent component and / or the engine speed-dependent component can be reduced when calculating the desired clutch torque.
- Embodiment of the invention provides that at least the gradient of a portion is appropriately limited when determining the starting function. Limiting the gradient of the throttle valve-dependent component and / or the engine speed-dependent component is particularly advantageous. By means of a suitable choice of the limits, in particular in the case of the gradient of the throttle valve-dependent portion, the influence of the portion can be reduced to such an extent that undesired acceleration of the vehicle can be avoided.
- the method according to the invention can be used for electronic clutch management (EKM) as well as for an automated manual transmission (ASG).
- EKM electronic clutch management
- ASG automated manual transmission
- the method according to the invention can be used in continuously variable CVT transmissions.
- FIG. 1 is a block diagram of the invention
- FIG. 2 shows a diagram with a basic sequence of a starting process
- FIG. 3 shows a diagram with a starting process with a tip-in
- FIG. 4 shows a diagram with a starting process with back-out.
- FIG. 1 shows a starting strategy in the form of a block diagram. This is, in particular, a start-up function that is compatible with global control and in which the start-up speed is adjusted.
- the accelerator pedal angle PWG, the engine speed n_mot, the transmission input speed n_get and the engine torque Me are provided as input variables. These input variables are processed to the desired clutch torque M_Rsoll as the output variable.
- a starting speed is determined via a starting target speed calculation, which is compared with the engine speed and serves as an input variable for the first phase (adjusting the starting speed).
- This input variable is converted into a torque contribution M_P1 and M_l via a PI controller with the parameters KP1 and KI1.
- the engine speed is compared with the transmission input speed and serves as an input variable for the synchronization phase.
- a PI controller with parameters KI2 and KPp2 is also provided in the synchronizing block, so that a torque contribution M_P2 is output.
- the I component of the PI controller is added to the I component of the PI controller of the start-up speed control block and fed to an integrator. The output variable of the integrator then forms the torque component M_l.
- the engine speed and the transmission input speed serve as input variables for the factor calculation, in which weighting is carried out with a speed ratio SR, which is defined by the quotient of the transmission input speed and engine speed.
- This weighting is carried out by the functions U (SR) and f 2 (SR).
- the function (SR) serves as an input variable for the adjustment of the starting speed block and the function f 2 (SR) serves as an input variable for the synchronization block.
- the engine speed is also provided as an input variable for the damping component.
- the function fi (SR) also has an influence on the damping component, so that a damping moment contribution M_D is output as the output variable.
- the engine torque is weighted by the factor calculation and forms an input variable for the global control. Furthermore, the engine speed and the transmission input speed are provided as input variables for the global control. A torque contribution M_GIob is output as the common output variable.
- FIG. 2 shows a starting process over time.
- the diagram is divided into the first phase (adjusting the starting speed) and the second phase (synchronizing or reducing slip).
- the diagram shows the curves of the starting speed n_Anf, the engine speed n_mot and the transmission input speed n_get.
- the engine speed is adapted to the starting speed so that it coincides with the course of the starting speed at the end of the first phase.
- the engine speed is adjusted to the transmission input speed and thus leaves the course of the starting speed.
- the engine speed and the transmission input speed are approximately identical, so that the further course of the engine speed and the transmission input speed is identical. From this point on, the engine speed and the gearbox input speed are synchronized.
- FIG. 3 shows a start-up process with a tip-in.
- the picture comprises two representations, among others the target clutch torque M_Rsoll and the engine speed n_mot with a solid line, the transmission input speed n_get with a dotted line and a throttle valve-dependent factor K ( ⁇ ) and the throttle valve angle DKLW are shown with a dashed line over time.
- the diagram shows the effect of the gradient limitation of K ( ⁇ ) when starting with a tip-in.
- the limited gradient of K ( ⁇ ) can be seen in the upper illustration. Because of this limitation, a collapse in the desired clutch torque M_Rsoll following the tip-in can be largely avoided. It must be noted, however, that a compromise must be made in tuning the gradient.
- FIG. 4 shows a start-up process with a back-out.
- the picture includes two representations, u. a.
- the target clutch torque M_Rsoll and the engine speed n_mot with a solid line, the transmission input speed n_get with a dotted line and a throttle valve-dependent factor K ( ⁇ ) and the throttle clutch angle DKLW with a dashed line are shown over time.
- the diagram shows the effect of the gradient limitation of K ( ⁇ ) when starting with back-out.
- the limited gradient of K ( ⁇ ) can be seen in the upper illustration.
- An extremely flat increase in K () allows the clutch to be pulled shut suddenly before synchronizing n_mot and n_getr. suppress dig.
- a gradient limitation to one or more parts is advantageous for determining the desired clutch torque, so that in particular the starting functionality of an automated clutch and / or an automated transmission is improved.
