Definitions
- the invention relates to an apparatus and a method for reducing a rotational deformity of a drive train of a hybrid vehicle, wherein ' the drive train comprises an internal combustion engine, an electric motor and a crank case.
- Rotationalities by means of passive erosion elements such as e.g. A dual mass flywheel (DMF) or a speed adaptive absorber (DAT) to combat.
- passive erosion elements such as e.g. A dual mass flywheel (DMF) or a speed adaptive absorber (DAT) to combat.
- DMF dual mass flywheel
- DAT speed adaptive absorber
- active compensation functions are known.
- active compensation functions take into account the effect of the optionally installed passive members, e.g. ZMS and DAT, and make an active compensation of the disorders in symbiosis with these.
- sensory signals of the drive train such as e.g. Speeds, moments or longitudinal accelerations, processed and compared with reference values, in order to control corresponding actuators depending on a control error.
- regulations of this type are limited in their usable bandwidth due to signal propagation times and actuator limitations.
- Cutoff frequencies are typically between 10 Hz and 20 Hz, depending on the drive topology (ie, engine design, etc.) and actuator quality, so that concepts of this type are suitable for cancellation of jerking frequencies and other low-frequency noise, but do not cover the entire frequency spectrum of rotationality can.
- the invention proposes a device for reducing a Drehuniformity of a drive train of a hybrid vehicle.
- the powertrain includes a combustion engine, an electric motor and a crankshaft.
- a reduction or eradication of Drehunförmtechnik is carried out by a control of the electric motor.
- the control is designed as an adaptive feedforward control.
- Feedforward control is referred to in English literature as Feed Forward Control.
- the adaptive feedforward provides a drive signal to the electric motor that represents a desired torque to be generated by the electric machine such that it outputs torque at least approximately inverse to the rotational torque to the crankshaft for superimposing the torque generated by the engine ,
- the invention further proposes a method of reducing torsional stiffness of a powertrain of a hybrid vehicle, wherein the powertrain includes an internal combustion engine, an electric motor, and a crankshaft.
- a reduction or eradication of Drehunförmtechnik is carried out by a control of the electric motor.
- the control is carried out with an adaptive feedforward control (feed forward control), which provides a drive signal for the electric motor, which represents a desired torque to be generated by the electric motor, so that this at least approximately inverse torque to the Drehunförmmaschine to the Crankshaft for superimposing the torque generated by the internal combustion engine emits.
- feed forward control feed forward control
- the e-machine for the eradication of Drehunförmmaschine.
- This is not controlled by a classic control, which typically only low-frequency noise can cancel up to 15 Hz, but using an adaptive feedforward, with which also vibrations in the audible range can be reduced or redeemed.
- This procedure is based on the recognition that the frequency components to be canceled depend on the engine speed and the frequency to be canceled is known ab initio. This knowledge can be in the pilot control can be used to redeem or reduce the corresponding vibrations.
- the running quiet of the engine can be increased.
- unwanted vibrations in the drive train can be damped.
- the apparatus and method can be further used to acoustically improve the noise of the internal combustion engine.
- passive powertrain eradication elements e.g. Dual-mass flywheels or speed-adaptive absorbers, can be saved. The latter is possible in particular because a high-quality function of the adaptive precontrol can be used.
- the pilot control can be fed as an input variable to a metrologically detected rotational speed of the internal combustion engine for processing.
- the feedforward control can be supplied with a frequency vector which can be generated from the rotational speed of the internal combustion engine and with the frequencies which are contained in a signal representing the rotational noise.
- the precontrol is supplied as an input variable with a metrologically detected rpm of the internal combustion engine for processing.
- the feedforward control in the method according to the invention is supplied with a frequency vector which can be generated from the rotational speed of the internal combustion engine and at the frequencies which are contained in a signal representing the rotational irregularity.
- the frequency vector can be generated by means of a frequency generator.
- a metrologically sensed speed of the electric motor can be fed to adapt the pilot control as a further input variable for processing, which includes a residual disturbance of rotational irregularity.
- a metrologically detected speed of the electric motor is supplied, which includes a residual disturbance Drehunförmmaschine.
- the adaptive feedforward control for processing for predetermined engine orders comprises information about which in the Drehuniformity representing interference signal contained frequencies.
- the adaptive feedforward controller processes information about the frequencies contained in the disturbance signal representing the rotation irregularity for given motor orders.
- the adaptive precontrol of the device according to the invention comprises in a further
- Embodiment of a disturbance observer which is designed to generate an A-matrix.
- An A matrix is used in a manner known to those skilled in the design or definition of a scheme.
- attenuation is considered in the A-matrix.
- Fig. 1a, 1b a temporal section of a rotational speed or a torque of a
- FIG. 2 is a schematic representation of an embodiment according to the invention of an adaptive feedforward control for reducing the torsional rigidity of the drive train
- FIG. 3 shows a schematic representation of the control concept of a disturbance variable observer which can be used according to the invention for realizing the adaptive precontrol.
- the following description is based on a hybrid powertrain of a vehicle with an internal combustion engine and an electric motor (electric machine), in which the electric motor is able to superimpose the torque path of the internal combustion engine to the driven axle (s). If in the present description of an electric motor is mentioned, this can be operated either in an electromotive or in a regenerative operation.
- the torque delivered by the internal combustion engine is subject to periodic disturbance torques due to free mass moments of inertia, combustion spikes and secondary effects of the engine aggregates. This is illustrated by way of example in FIGS. 1a, 1, wherein in each case a time segment of the crankshaft rotational speed n «w or of the torque M m applied to the crankshaft is shown.
- interference signal only a disturbing torque applied to the crankshaft of the drive train is considered as interference signal.
- the summation of all the disturbing moments 2 ' is referred to as non-rotationality.
- the rotational irregularity i.
- the occurrence of the frequencies calculated in formulas (2) and (3) should be optimally eradicated in the drive train in order to avoid acoustic and component load limits.
- a feedforward control is used for this purpose.
- This uses in addition to the speed of the engine as a reference, the knowledge of the frequencies contained in the signal in order to replicate the Drehunförmtechnik as well as possible and extinguish it by a suitable actuator.
- the signal generated in this way is adjusted in phase position and amplitude to the interference signal.
- the precontrol algorithm is adapted with a measured signal containing the residual disturbance. This is done by means of a precontrol algorithm which is based, for example, on a disturbance observer. Alternatively, for example, a so-called adaptive notch filter could also be used.
- further implementation options are conceivable.
- FIG. 2 A schematic representation of the operation of a pilot control is shown in Fig. 2.
- the internal combustion engine is marked with VM, the electric motor with EM.
- a first sensor 51 for example, a Kurbeiwelle ngeber
- a second sensor S2 for example, a rotor position sensor
- the crankshaft sensor S1 detects a rotational speed of the internal combustion engine.
- the rotor position sensor 52 detects a rotational speed n EM of the electric motor.
- a frequency vector ⁇ is formed in the block FG.
- the block FG represents a frequency generator.
- the frequency vector ⁇ contains those frequencies that are suspected in the interference signal. These frequencies may depend on the speed n K w of the engine VM or assume independent constants. The procedure for determining the frequency vector will be described in more detail below.
- block SGB which represents a disturbance observer, the system dynamics of the periodic oscillations contained in the frequency vector ⁇ , ie the respective frequencies of the frequency vector, are described. These are corrected in SGB with respect to their phase and amplitude with the aid of an error signal e, summed up and provided as the desired torque M E M.
- the speed of the electric machine EM measured by the rotor position sensor S2 is fed to a block SMS, a disturbance torque estimator.
- the disturbance torque estimator SMS forms from the measured electric machine speed n EM an estimate of the disturbance torque which lies on the crankshaft. A possible implementation is also explained below.
- Frequency generator FG and disturbance observer SGB form the adaptive feedforward control F.
- the rotor position sensor S2 and the disturbance torque estimator SMS represent a measurement path H of a precontrol.
- a controlled system P which is not shown explicitly in FIG. 2, is given between the drive torque M 0 and the detection of the electric machine speed n EM .
- the structure of the disturbance observer ' SGB is shown in FIG.
- x represents a vector with the states of the oscillations to be imaged, A the matrix for describing the system dynamics, e the remaining residual disturbance moment and L the matrix of the read speeds for adapting the states to the measured disturbance dynamics.
- the vectors ⁇ and c parameterize the system matrix A with respect to the frequency and the attenuation in the individual sinusoids.
- A denotes an A matrix generator, to which the frequency ⁇ ⁇ and the damping are supplied as input variables.
- the choice of the learning speeds must always be done in pairs for the two states of a sine wave.
- the different frequencies can be weighted differently. Only the two states of the same frequency must find the same learning speed.
- the invention thus proposes the use of an adaptive precontrol in order to eliminate or at least reduce the rotational irregularity of an internal combustion engine by means of an electric motor.
- the adaptive feedforward control uses the knowledge that the frequency components to be canceled depend on the engine speed and whose frequency is known for each motor arrangement. In the above description, only one disturbance observer for implementing a solution is explicitly described. It is readily possible to realize such a concept with an LMS filter or similar variants.
