Or in power supply line 115 correct voltage level diagnosis.In addition, the diagnosis should especially detect control equipment or identification device
100 and as the motor phase line 115 between the motor of customer 110 decline.The decline of phase is currently interpreted as powering
It is interrupted in one of route 115.That is, if occurring the interruption in rupture of line or generally one of power supply line 115 now
160, just as shown in figure 1 by shown in the interruption of the first power supply line 115a, then as the phase of the motor of customer 110 or around
Electric energy is no longer supplied in group.In addition, motor 110 will rotate in the case where error map (Fehlerbild), however
Power will be lowered, and revolution will be more uneven and since the vibration sound intensity rises.Assume that B6 bridge 120 deactivates in design so far
It is living, also that is, all high-side transistors 135 and low side transistors 145 are turned off.Control (its tool of diagnostic network 165 inside equipment
Have respectively between supply voltage terminal 140 and the first power supply line 115a and in supply voltage terminal 140 and the second supply lines
The resistance of such as 2R between the 115b of road and the resistance R being connected between third power supply line 115c and ground potential terminal 150)
Lead to the voltage level limited in motor phase 115 now, the motor is mutually under normal operating conditions by as power consumption
The exterior motor of device 110 can be considered as short circuit.Here, phase voltage passes through analog channel 170 (ADC) quilt of computer 155
Detection and analysis.The phase voltage should be within the scope of centainly according to supply voltage Ubat.If present first motor phase
115a, motor phase 115b or third motor phase 115c decline are (also that is, in corresponding power supply line 115a, 115b or 115c
In interrupt), then the voltage on third phase 115c to read back due to the actually active diagnostic network 165 that changes now and
It reduces, and therefore can reliably identify that route declines.
Fig. 2 shows the circuit diagrams 200 of the interruption in one of power supply line 115 of motor phase for identification.Here, scheming
The phase voltage U detected on third power supply line 115c at ADC channel 175 is depicted on the ordinate of chart in 2115c。
(that is, correspond to previously given rated value U phase voltage is maximumsoll) the first range 210 in, it can be assumed that " normal (IO)
State ", all power supply lines 115 are all correctly connected customer 110 in the case where in this state, namely are not present
It is disconnected, interruption 160 as shown in figure 1.If applying the phase voltage having than value lower in range 210 on ADC channel 175 now
U115c, as the situation in Fig. 2 in range 220, then it may be assumed that there are the first connection line 115a or the second connection lines
Interruption 120 in 115b.If being measured at ADC channel 175 or even than voltage also lower in range 220 or even no longer
Measure voltage (as shown in the range 230 in Fig. 2), then it may be assumed that in third power supply line 115c
It is disconnected.In this regard, when being detected at ADC channel 175 lower than the voltage in the first range 210 namely lower than voltage rating
Phase voltage U115cWhen, it can be assumed that " abnormal (NIO) " state of connection line 115.
One important aspect of scheme presented here is the system introduced extended below or for identification to power consumption
The identification device 100 of the interruption of the power supply line 115 of device, that is, the diagnosis of the interruption of the motor phase or power supply line 115 that decline
It can also be identified even if in the case where motor 110 is effectively run.
The decline of motor phase 115 is mainly in the case where controlling equipment or identification device 100 activates for example due to being always
System 100,110 vibration (such as at the gear-box extended on motor 110 being not shown in Fig. 1) and occur.Therefore this
In the purpose of scheme introduced be that decline the following change for completing Diagnostic Strategy: is identified during the motor 110 effectively run
Route 115.Therefore guarantee the correct control of motor 110 at any time, and avoid including that power disturbance at motor 110 exists
Interior vicious rotation, until the error control including safety critical state.
Scheme presented here illustrates by B6 bridge circuit 120, wherein however can be bright for professional
Really it is appreciated that, identify that the principle of the interruption of the power supply line 115 of customer 110 also can be applied to (such as non-multiphase)
The identification of the individual power supply line 115 of customer 110.Therefore, a kind of scheme is also disclosed in current description, in the program
In disclose the interruption of power supply line 115 so that claim is also supported by current description on its width.
In order to obtain the improvement or extension of the identification device 100 according to Fig. 1 now, now to the system in Fig. 1 slightly into
Row changes.In the case can as in the block diagram in Fig. 3 it can be seen that as cancel diagnostic network 165 component with
And ADC channel 175.Can exist in operation that is, for example through the second power supply line to the diagnosis of the appearance of interruption
It is carried out when 115b is to the electric current flowing of motor 110 and from current reflux of the motor 110 by third power supply line 115c.In
This, the first half-bridge 130a is in tri-state state, and the second half-bridge 130b is in PWM state, and third half-bridge 130c is in
In " downside is effective " state.When motor 110 is rotated, the first power supply line 115a is brilliant by the first high side at the time of determining
Body pipe 135a is loaded the current potential of supply voltage terminal 140, wherein then electrical power cannot be conveyed to motor due to interrupting
110。
Fig. 4 shows the detail drawing of a part of the block diagram of the identification device 100 according to the diagram in Fig. 3, so as to preferably
Illustrate the working method of scheme presented here.
In order to connect the high-side transistor 135 of B6 bridge, needing to be higher than cell voltage, (cell voltage is currently assumed
Supply voltage Ubat) voltage.Due to this reason, internal charge pump CP is provided in bridge driver 125, as in Fig. 4
Shown in (CP in Fig. 5).The internal charge pump powers to the inside floating gate driver FG of bridge driver 125, with
Just the high-side transistor 135 of each half-bridge 130a, 130b and 130c are controlled.Based on design presented here, typically several hundred uA
Leakage current IL in range from the high side source terminal 400 of bridge driver 125, (power with here first by the high side source terminal
Route 115a is conductively connected) outflow.
In order to be identified by the overcurrent of half-bridge 130a, which is equally gathered around as identification device 100 in inside
Have identification cells D S, such as detect in an analog fashion external power transistor 135 (external power transistor herein by
Be designed as MOSFET) terminal 400 and 410 on dram-source voltage.For example, detection unit DS have about from -1.5V to
The measurement range of 1.5V, and thus allow extremely accurate to detect outer between the terminal 400 and 410 of (high side) transistor 135a
Portion's voltage.
It is notified when computer 155 is inquired by detection unit DS (high side) the transistor 135a's detected by SPI communication
Voltage value between terminal.
The scheme that motor presented here for extension mutually diagnoses utilizes these characteristics.Here, can diagnose in block
Interruption 160 when commutation or comparable commutation in one of motor phase or power supply line 115, wherein related half-bridge 130 is (here
Half-bridge 130a) just in the tri-state stage.Here, the second half-bridge 130b was in the PWM stage in block commutation, and third half
Bridge 130c was in the ground connection stage, just as can be seen in Figure 3.In the case where motor line 115 correctly connects, source
In pole leakage current IL inflow motor 110, here, the voltage level on source electrode pin 400 is between 0V and Ubat.
In the case where motor phase 115 declines, leakage current IL be cannot flow into motor 110, instead of this (here the
One) the inside high side diode (diode D1a here) of high-side transistor (135a) is by the electric current towards with supply voltage Ubat
Supply voltage terminal 140 direction export.It is consequently formed and the voltage determined is flowed by the diode current in diode D1a
It drops, therefore the voltage level on source electrode pin 400 rises to Ubat+Udiode in the case where declining route.
Diagnosis presented here can be realized the analysis after each commutation transformation of the phase 115 in tri-state mode.
Here, minimum time or waiting time should be waited, therefore will not be due to the phase of the decaying by high side diode (D1a here)
