Definitions
- the invention relates to a method with the features according to the preamble of
- EP 2 067 681 B1 limits the maximum permissible transmission input shaft speed for vibration suppression in the case of vibration detection. As a result, a target creep speed can no longer be achieved and the continuous slip during creep is relatively high, which causes a generally undesirable energy input into the clutch.
- Anti-spin control requires a highly dynamic, low-wear actuator
- Such actuators are relatively complex and expensive, moreover, simpler, less dynamic actuators are sufficient for all other functions of a clutch.
- the object of the present invention is to develop a creep strategy which
- CONFIRMATION COPY closed quickly and the rate of change of the slip speed is high.
- Critical resonance ranges in which chatter vibrations could be excited are quickly traversed by the clutch actuator.
- Figure 4 shows the case when the vehicle creeps on a slight slope of the road or loaded. If the creep strategy here is purely position-controlled or torque controlled, the slip is no longer or only slowly degraded and the slip frequency persists for a long time in the resonance-critical speed range. There then occur clearly noticeable and unwanted juddering vibrations.
- a method for preventing or reducing juddering vibrations in a drive train of a motor vehicle having an automated friction clutch and an automated transmission is provided.
- the friction clutch is actuated such that the slip in the friction clutch with a predetermined slip change rate An S ip / At decreases when there is slippage in the friction clutch at the beginning or during a vehicle creep, and as long as the slip speed n S
- a method for preventing or reducing juddering vibrations in a drive train of a motor vehicle having an automated friction clutch and a controller for controlling an opening degree of the friction clutch and an automated transmission.
- the controller as a controller setpoint input a slip change rate An S ip / At is given if there is slippage in the friction clutch at the beginning or during a creep of the vehicle and as long as the slip speed n S
- the controller is given a first size as a controller setpoint default if at the beginning or during a creep of the vehicle, the slip speed is above the critical resonance range and / or that the controller specified a second size as a controller setpoint is at the beginning or during a creep of the vehicle, the slip speed is below the critical resonance range.
- the first quantity is a clutch torque change rate or a clutch travel change rate or a clutch pressure change rate or a target creep speed.
- the second variable is a target creeping speed or the maintenance of a slip change default until or shortly before reaching synchronous, or a specification of a clutch travel change rate or a clutch pressure change rate or a clutch torque change rate to slip reduction or beyond that.
- iP 2 is located.
- ip / At is a function of the operating conditions
- iP 2 can be determined from vehicle measurements or powertrain simulations .
- a device for preventing or reducing juddering vibrations in a drive train of a motor vehicle having an automated friction clutch and an automated transmission. According to the invention, it is provided that the device carries out one of the methods described above.
- the device has a regulator for controlling an opening degree of the friction clutch.
- the method according to the invention as well as the device according to the invention have the advantage that in slip-critical rotational speed ranges a slip change rate is set or adjusted which is so high that the critical range of the
- Coupling actor is quickly passed through and thus chatter vibrations are avoided or mitigated.
- FIG. 5 with the method according to the invention or the invention
- FIG. 6 with the method according to the invention or the invention
- the slip speed is kept outside the critical resonance range
- Figure 7 shows an example of the three controller setpoint specifications for the different
- a creep strategy should regulate the course of the slip speed in the critical resonance range so that the rate of change of the slip speed is sufficiently high in order to drive through the critical range quickly and steeply.
- the proposed creep strategy divides the control into three control ranges I, II and III in order to avoid slip-speed-dependent picking motions:
- the slip speed n S ii P is at the start of the creep in the still uncritical
- the Kriechregler in known manner as a set value, a clutch torque change rate (figure 7, 1), or a clutch path change rate or a clutch pressure change rate predetermined.
- the clutch is moved close to 20 Nm / s (starting from a rest position or the touch point).
- the slip speed n sNp now reaches the critical resonance range at n S
- the controller setpoint default to the specification of a certain slip rate to An S
- a typical value is An S
- ip / At> 150 rpm / s (rpm / s: revolutions per minute per second).
- ip1 can be determined from vehicle measurements or powertrain simulations during development. Their determination is left to the person skilled in the art taking into account the individual technical case.
- the rate of slip change should be selected such that the critical resonance range is passed quickly in order to avoid excitations. However, for reasons of comfort, of course, the rate of slip change is to be limited to a maximum rate of slip change, otherwise the vehicle will jump in phase II.
- the slip rate may be a constant or an operational condition dependent function.
- the controller setpoint specification can be changed back to a target creeping speed (FIG. 7, III), for example in a known manner. Depending on the ratio and / or load and / or slope of the slip is then completely degraded or held a slip outside the critical resonance range. These two situations are distinguished in FIGS. 5 and 6.
- a target creeping speed (FIG. 7, III)
- FIGS. 5 and 6 instead of the target creep speed, other control options are optionally also conceivable, such as maintaining a slip change preset until or shortly before reaching synchronous, or specifying a clutch travel change rate or a clutch pressure change rate or a clutch torque change rate until slip reduction.
- FIG. 7 again shows, by way of example, the three controller setpoint specifications for the different slip ranges I, II and III.
- the manipulated variable can then be a clutch position XCluPos or eg a clutch pressure.
- a creep strategy is disclosed for avoiding slip speed dependent pickup vibration excitations in automated transmissions with eg dry single or multiple clutches. In critical-critical slip-frequency ranges, the creep strategy regulates a rate of slip change that is so high that the critical range is quickly traversed, thus preventing or attenuating picking vibrations.
