Definitions
- the invention relates to a method for optimizing a drive dynamics of an electric motor, preferably for use in a hydrostatic
- Clutch actuator of a motor vehicle in which a commutation of a plurality of pole pairs of the electric motor takes place in dependence on a position of a rotor of the electric motor, wherein the position of the rotor is derived from a phase angle, which occupies the rotor to a stator of the electric motor and which of a Sensor is measured and forwarded to a control unit which controls the commutation in dependence on the phase angle.
- a method for checking a commutation quality of an electronically commutating electric motor is known from DE 10 201 1 086 583 A1, which has several phases in a drive system of a motor vehicle, in particular in a hydraulic actuation system of a friction clutch, and with a rotor of the electric motor Angle of rotation is monitored by an absolute measuring rotor position sensor.
- DE 10 2013 207 317 A1 discloses a method for controlling an electric motor, in particular for actuating actuators in a motor vehicle, in which a momentary motor voltage is compared with a voltage limit before it is applied to the electric motor, and the voltage limit from a Impedance of the electric motor is derived.
- a momentary motor voltage is compared with a voltage limit before it is applied to the electric motor, and the voltage limit from a Impedance of the electric motor is derived.
- the invention is therefore based on the object of specifying a method for optimizing a drive dynamics of an electric motor, in which the thermal load of the electric motor is reduced.
- the object is achieved in that an offset phase angle is added before each commutation to the measured phase angle and the sum phase angle of the commutation thus formed is used as the basis.
- an offset phase angle to control the commutation becomes a Simulates the position of the rotor, which causes the control unit to set a higher rotational speed of the rotor at a given load.
- the desired position of the rotor is reached faster, which represents an increase in the dynamics of the control. Since the motor current depends on the load, overheating of the output stages of the electric motor is reliably prevented.
- the offset phase angle is determined as a function of an effective motor constant, which is calculated taking into account a maximum motor current which just allows a permanent thermal load on a final stage controlling the electric motor within a predetermined period of time. Due to the fact that different torque / motor current ratios are set by the offset phase angle, the motor current can be calculated or also measured.
- the effective motor constant is assigned to an offset phase angle which is used to increase the sum phase angle of the next commutation to increase the drive dynamics of the electric motor. To prevent destruction of the final stage of the electric motor by a high motor current, the motor current is applied depending on the size in varying periods of time at the final stage of the electric motor.
- effective motor constants are stored in the control unit as a function of offset phase angles in a look-up table.
- the associated offset phase angle is read from the table and added to the measured phase angle for setting the sum phase angle. This allows a comfortable calculation, which requires little computing time.
- a motor current for the commutation is calculated in a starting phase starting from a predetermined start offset phase angle, while for subsequent commutations the offset phase angle of the immediately preceding commutation is always taken as the basis for the calculation of the motor current. This always takes into account the instantaneous situation on the electric motor.
- the maximum motor current allowed in a given period of time represents a current threshold value, which is compared with the motor current calculated on the basis of the effective motor constant, and falls below it of the current threshold value, an addition of the offset phase angle to the measured phase angle is carried out by the calculated motor current. This ensures that it is checked before each commutation process whether the calculated motor current does not exceed the maximum permitted motor current, which prevents overheating of the output stage.
- the offset phase angle is set to zero when the rotor of the electric motor has a low rotational speed.
- the presence of a low rotational speed allows conclusions to be drawn that the rotor is working in the area of a reversal of rotation, where high current fluctuations occur.
- the influencing of the commutation by the current fluctuations produced by acceleration or deceleration of the rotor is prevented by setting the offset phase angle to zero for a predetermined short time, so that the motor current can weaken again before the next commutation.
- an engine flow exceeding the maximum motor current is applied to the electric motor in a pulsating manner in short periods of time.
- the drive dynamics of the electric motor is further improved.
- the short drive and the power amplifier loading high currents can be used, since due to the short period of concern, a thermal load on the power amplifier is limited.
- the shorter the time period the higher the motor current exceeding the maximum motor current. This reliably prevents overheating of the output stage.
- the offset phase angle set according to the effective motor constant is set to be pulsating. This also contributes to a dynamic increase for a specific actuator application and thus a faster actuation of the actuator is achieved.

- the drive system 1 is shown in the form of a hydraulic actuation system 2 for a friction clutch 3, as provided for example in duplicate to a respective friction clutch 1 of a dual clutch transmission with two partial transmissions in a drive train 1 of a motor vehicle.
- the actuating system 2 includes a housing 4, in which a pressure piston 5 is axially displaced axially from the rotor 6 of an electronically commutated electric motor 7 with the interposition of a transmission 8 for converting the rotational movement of the rotor 6 of the electronically commutated electric motor 7.
- the electronically commutated electric motor 7 is driven by a control unit 9, wherein the electric motor 7 has an output stage 10.
- the control unit 9 controls the commutation of the electric motor 7 on the basis of the rotor position sensor 1 1 supplied rotation angle cpo , which is arranged opposite the rotor 6 frontally.
- the slave cylinder 13 Via a pressure line 12, the slave cylinder 13 is acted upon by the pressure generated by the pressure piston 5 during an axial displacement in the housing 4, whose piston actuates the pressure plate of the friction clutch 3.
- the electronically commutated electric motor 7 has three coil bodies acted upon by a current in three phases U, V, W, which are energized one after the other by means of the phases U, V, W, so that a magnetic alternating field is commutated, which couples the pole pairs to the rotor 6 repels and thus forces a rotation of the rotor 6.
- the control unit 9 is in a memory not shown a
- FIG. 2 shows an electric motor 7, which is connected to the output stage 10. Furthermore, the output stage 10 is connected to a power supply 20, which is also positioned in the control unit 9.
- the electric motor 7 is actuated by the control unit 9 by means of a block commutation, which means that the electric motor 7 is driven so that always one of the phases U, V, W of the electric motor 7 is de-energized while the other two phases U, V, W are energized.
- the phases U, V, W are tapped at center taps of the output stage 10.
- the output stage 10 is designed as a bridge circuit with electronic switching elements.
- B-bridge six electronic switching elements 14, 15, 16, 17, 18, 19 are provided, which are advantageously designed as field effect transistors.
- the field effect transistors are electronically commutated, thereby generating a rotating field.
- the field effect transistors are only shown as switches. Between the switches 14 and 15, the phase U, between the switches 16 and 17, the phase V and between the switches 18 and 19, the phase W of the electric motor 7 is tapped.
- Fig. 3 the dependence of the current flowing through the output stage 10 motor current I over the time t is shown.
- the time intervals are decisive for ensuring that the output stage 10 is not overheated when the maximum motor current I is present.
- a maximum motor current of 10 amps can be used indefinitely almost at all outside temperatures T, without destroying the field effect transistors 14, 15, 16, 17, 18, 19.
- Higher motor currents of about 20 amperes, for example, at ambient temperatures T above 0 ° C only to 0.4 seconds at the output stage 10 without problems.
- Motor currents up to 50 amperes may only be applied at temperatures T below 0 ° C at the output stage 10, if destruction of the power amplifier 10 is to be prevented.
- N N number of inductors of the electric motor, Lmot inductance.
- each effective motor constant K ee ff is electrically associated with an offset phase angle cp 0 ff in degrees.
- the calculation is based on a not to be exceeded maximum motor current of 10 amperes, which is drawn as threshold i hold zoom. If the calculated motor current i_theo is smaller than the limit i hold. If this is the case, then a phase angle cpo is measured by the rotor position sensor 11. At this phase angle ⁇ 0 , an offset phase angle cp 0 ff is added, which is added by means of a newly determined effective modulus.
- torkonstante ee ff K is determined from the lookup table.
- the new effective motor constant K e _eff is determined on the assumption from equation (1) that the maximum motor current to be achieved is 10 amperes.
- This new summation phase angle cps thus formed by addition is given to the control unit 9 for setting the next commutation.
- the control unit 9 is simulated a phase angle cps, which is thus actually absent. Due to the thus adjusted changing torque-motor current ratio, a maximum rotational speed of the rotor 6 is achieved with reduced torque to take the desired rotor position.
- the actual phase angle cpo assumed by the rotor 6 is again measured by the rotor position sensor 11.
- the offset phase angle cp 0ff is set to zero and the pre-control described is suppressed. Also set to zero, the offset phase angle co ff , if by short-term strong fluctuations in the motor current I, a high dynamic change is displayed, which can be done for example by acceleration or braking operations of the electric motor 7. This occurs in particular when the electric motor 7 makes a change of direction.
- the offset phase angle (o ff is set to zero until the strong fluctuations in the motor current have subsided, and the described pre-commutation method is then restarted.
- the maximum motor current exceeds Motor current applied pulsating to the electric motor 7. It is assumed that the motor current can be varied in height and is not limited to a maximum motor current of 10 A. The time intervals in which the motor current exceeding the maximum motor current is applied to the electric motor 7 are shorter, the higher the excess motor current. If, for example, a maximum motor current i hold of 20, 30 or 40 amperes is set as the threshold value, the effective motor constant k ee ff and the offset phase angle cp 0 ff are adjusted so that an increasing motor current is present for the set time interval. In a next phase of the commutation, when the theoretical motor current i_theo is greater than the threshold value i hold, the threshold value i hold is reset.
- FIGS. 4 to 8 show different characteristic curves over time.
- FIG. 4 shows the effective motor constant K ee ff over time
- FIG. 5 shows the commutation angle cps over time
- FIG. 6 shows the load N over time
- FIG. 7 shows the rotational speed n of the rotor 6 over time

- the curve A denotes the corresponding parameters without the correction of the phase angle
- the curve B shows a phase angle correction at a low load
- curve C shows a continuously executed phase angle correction
- the curve D illustrates the phase angle correction with pulsed motor current. It can be seen that the angular correction with pulsed dynamics brings the best improvement in the rotational speed of the rotor 6 and a rapid bringing the rotor 6 to the desired position entails.
- Fig. 9 the average motor current applied to the electric motor 7 is shown for different time intervals. As shown, the considered activity time is assured by the use of the existing pilot strategy, considering the maximum motor current limit for the MOSFETs 14, 15, 16, 17, 18, 19 included in the final stage 10.
