Some vehicles are equipped with a power output device that outputs driving force, an internal combustion engine for a generator that charges electric power to a capacitor, and a generator.

In the above-mentioned vehicles, there is a technology for determining whether or not power generation is possible by using a means for detecting a state in which fuel cannot be supplied to the internal combustion engine before the start of power generation and a means for detecting a state in which power cannot be generated due to an abnormality in the power generation means.

However, in the technique described in Patent Document 1, in a vehicle equipped with a power output device and a power generation device, the generator and the internal combustion engine are individually diagnosed in the state before power generation, but the generator and the internal combustion engine are connected. There is no diagnosis of the connecting mechanism (gear and shaft).

Therefore, in the technique described in Patent Document 1, it is not possible to accurately determine whether or not a power generation device including a gear and a shaft connecting a generator and an internal combustion engine is in a normal power generation state or not before power generation.

That is, even if the generator and the internal combustion engine are normal before power generation, a defect in the connecting mechanism cannot be detected. If power generation is started while the coupling mechanism is out of order, the power generation device may be damaged.

The present invention has been made in view of the above circumstances, and an object of the present invention is to use a power generation system control device having a power output device and a power generation device in a state before power generation by an internal combustion engine.

It is provided with an abnormality diagnosis unit for determining whether or not the connection mechanism is abnormal.

According to the present invention, in a power generation system control device having a power output device and a power generation device, it is determined whether or not the connecting mechanism for connecting the generator and the internal combustion engine is abnormal in the state before power generation by the internal combustion engine. It is possible to realize a power generation system control device capable of suppressing damage to the power generation device.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Example 1)
FIG. 1 is an overall schematic configuration diagram of a vehicle system to which the first embodiment of the present invention is applied.

In FIG. 1, the vehicle 100 includes drive wheels 110, 120, 130 and 140, motor generators 310 and 320, inverter converters 220 and 230, an engine 330, a battery 300, and a host ECU 200 (electric control unit). The engine ECU 210 (engine control unit), the differential gear 340, and the CAN 400 (controller area network) are provided.

The upper ECU 200 has information on the vehicle operator and other functions, and transmits a command to each unit based on the received information. The inverter converter 220 for driving the vehicle receives the request transmitted from the host ECU 200, outputs a three-phase current, and the drive motor 310 for the vehicle generates a driving force. At this time, the inverter converter 220 is supplied with electric power from the battery 300.

The driving force generated by the motor 310 is transmitted to the drive shaft 350 via the differential gear 340, and finally the driving force is transmitted to the drive wheels 110, 120, 130 and 140, and the vehicle rotates to realize vehicle running. ..

In the power generation system, the host ECU 200 communicates with the battery 300, and when the remaining battery level of the battery 300 drops, a torque command is given to the engine control unit 210, and a power generation command of a rotation speed command is transmitted to the inverter converter 230.

The inverter converter 230 rotates the rotating shaft (shaft) 371 of the motor generator 320, and the engine 330 is started via the rotating shaft (shaft) 370 and the gear 360 of the engine 330. When the engine 330 is started, the motor generator 320 becomes a generator, and electric power is supplied to the battery 300. The rotating shaft 371 of the motor generator 320, the rotating shaft 370 of the engine 330, and the gear 360 constitute a connecting mechanism between the motor generator 320 and the engine 330.

FIG. 2 is a partial configuration diagram of a power generation system 6 including the inverter converter 230, the motor generator 320, and the battery 300 of FIG.

In FIG. 2, the power generation system 6 includes a control unit 1, a motor generator 320, an inverter converter 230, a rotation position detecting means 41, and a high-voltage battery 300.

The control unit 1 generates a PWM control signal and inputs the PWM signal to the circuit of the inverter converter 230 via the PWM signal output means 32. The circuit of the inverter converter 230 applies the power supply voltage of the high-voltage battery 300 to the armature coil of the motor generator 320 by controlling the switching element according to the PWM signal input from the control unit 1, and the three-phase alternating current Iu, Conduct Iv and Iw.

The motor rotates when the three-phase alternating currents Iu, Iv, and Iw conduct to the motor generator 230. The rotational force obtained by the motor generator 320 is transmitted to the engine 330 via the shaft 370 and the gear 360 to start the engine.

After the engine is started, the motor generator 320 becomes a generator and power is supplied to the high-voltage battery 300 via the converter 230 as the engine ignites.

The rotation position detecting means 41 calculates the rotation position θ of the motor generator 320 from the input of the rotation position sensor 4 such as a resolver. The current detecting means 7 is a Hall current sensor or the like, and detects three-phase alternating currents Iu, Iv, and Iw conducting to the motor generator 320. The power generation availability determination result Gen_Flag is transmitted from the control unit 1 to the upper ECU 200.

FIG. 3 is a block diagram of the control unit 1 shown in FIG.

In FIG. 3, the target torque calculation unit 11 uses the rotation speed command ω * of the motor generator 320 output from the upper ECU 200 shown in FIG. 2 and the rotation position θ detected by the rotation position detecting means 41 to give a target torque command. Calculate T *. Further, the target torque calculation unit 11 determines whether or not cranking is in progress, and acquires a cranking flag (Crank_Flag).

The threshold value calculation unit 12 uses the target rotation speed ω * output from the upper ECU 200, the engine temperature En_Tmp output from the temperature detector (not shown), and the outside air temperature Out_Tmp to set the upper limit T_Max of the load torque threshold and the load. The lower limit T_Min of the torque threshold is calculated.

The abnormality diagnosis unit 18 makes a load torque abnormality determination using the upper limit T_Max of the load torque threshold value, the lower limit T_Min of the load torque threshold value, the target torque command T *, and the cranking flag Crank_Flag, and acquires the determination result Gen_Flag.

The target torque correction unit 13 calculates the second target torque Tcor * using the first target torque command T * and the power generation enable flag Gen_Flag output by the abnormality diagnosis unit 18.

The current command generation unit 14 calculates the d-axis current command Id * and the q-axis current command Iq * using the second target torque Tcor *. The three-phase / dq conversion unit 15 converts the three-phase AC currents Iu, Iv, and Iw into d-axis current detection values Id and q-axis current detection values Iq using the rotation position θ.

The d-axis current command Id * output from the current command generation unit 14 is supplied to the subtractor 25, and the d-axis current detection value Id output from the three-phase / dq conversion unit 15 is subtracted from the d-axis current command Id *. Is output to the current control unit 16.

Further, the q-axis current command Iq * output from the current command generation unit 14 is supplied to the subtractor 26, and the q-axis current detection value Iq output from the three-phase / dq conversion unit 15 is the q-axis current command Iq *. Is subtracted from and output to the current control unit 16.

The current control unit 16 calculates the d-axis voltage command Vd * and the q-axis voltage command Vq * based on the outputs from the subtractors 25 and 26, and outputs them to the dq / three-phase voltage conversion unit 17.

The dq / three-phase voltage conversion unit 17 uses the d-axis voltage command Vd *, the q-axis voltage command Vq *, and the rotation position θ to use the U-phase voltage command value Vu *, the V-phase voltage command value Vv *, and the W-phase voltage. The command value Vw * is calculated and output to the gate signal generation unit 19.

Then, the gate signal generation unit 19 generates a PWM control signal which is a gate signal and sends it to the inverter converter circuit 230 via the PWM signal output means 32.

FIG. 4 is a block diagram of the threshold value calculation unit 12 shown in FIG.

In FIG. 4, the threshold calculation unit 12 includes a motor generator including an engine and a connection mechanism at low temperature, normal temperature, and high temperature, which are assumed in advance from the target rotation speed ω *, the engine water temperature En_Tmp, and the outside temperature Out_Tmp. It has a low-temperature load abnormal torque map 121, a normal-temperature load abnormal torque map 122, and a high-temperature load abnormal torque map 123 that store the load torque value applied to 230. The upper and lower limit thresholds T_Max and T_Min of the load torque abnormality are acquired by using predetermined threshold values for the abnormal load values obtained from these maps 121, 122 and 123.

FIG. 5 is a block diagram of the abnormality diagnosis unit 18 shown in FIG.

In FIG. 5, the target torque command T * calculated by the target torque calculation unit 11 and the upper limit value T_Max of the load torque abnormality obtained by the threshold value calculation unit 12 are compared by the comparator 181 and the target torque command T * is obtained. When it is larger than the upper limit value T_Max, the ON signal (high level signal) is output from the comparator 181 to the OR circuit 183.

Further, the target torque command T * calculated by the target torque calculation unit 11 and the lower limit value T_Min of the load torque abnormality obtained by the threshold value calculation unit 12 are compared by the comparator 182, and the target torque command T * is the lower limit value. When it is smaller than T_Mmin, the ON signal (high level signal) is output from the comparator 182 to the OR circuit 183.

If the output of both or one of the comparators 181 and 182 is an ON signal, the OR circuit 183 outputs the ON signal to the multiplier 184. In the multiplier 184, if the ON signal is output from the OR circuit 183 and the cranking determination result Crank_Flag obtained by the target torque calculation unit 11 is ON (during cranking), it is diagnosed as a load torque abnormality. With Gen_Flag turned ON (load torque abnormality), the determination result is transmitted to the upper ECU 200 connected to the target torque correction unit 13 and the control unit 1 of FIG.

If the cranking determination result Crank_Flag is ON (during cranking) and the target torque command T * is a normal value within the range of the upper limit value T_Max and the lower limit value T_Min, it is determined that the load torque is normal and Gen_Flag is turned off. As (normal load torque), the determination result is transmitted to the upper ECU 200 connected to the target torque correction unit 13 and the control unit 1 of FIG.

If the cranking determination result Crank_Flag obtained by the target torque calculation unit 11 is OFF (during power generation), the abnormality diagnosis has already been performed. Therefore, the abnormality diagnosis result Gen_Flag is set to OFF (normal load torque) and the target torque is corrected. The determination result is transmitted to the upper ECU 200 connected to the unit 13 and the control unit 1 of FIG.

FIG. 6 is a time chart from cranking of starting the engine 330 by the motor generator 320 to power generation in the first embodiment.

In FIG. 6, the solid line 21 indicates the rotation speed [rpm] of the motor generator 320, the target torque (dotted line) 20 indicates the first torque command T * [Nm], and the alternate long and short dash line 22 indicates the target rotation speed (rotation speed command). ) Is shown.

Section (a) -1 is a section for raising the internal combustion engine to a certain number of revolutions, and section (a) -2 detects a load torque abnormality in Example 1 of the present invention in a certain cranking. This is the section for diagnosing the motor / generator. Further, no power is generated in the sections (a) -1 and (a) -2.

The section (b) is a section in which power is generated by the internal combustion engine (engine 330).

Section (a) -1 is a section for raising the generator from the engine stopped state to a certain constant rotation speed, and is a transient state. In this section (a) -1, if fuel cannot be supplied to the engine 330 or power cannot be generated due to an abnormality in the motor / generator 320, each diagnosis functions and a stop command is issued.

In section (a) -2, the engine 330 and the motor generator 320 are normally started, and the state is a steady state. The torque command in the steady state is the side where the motor generator 320 is ahead of itself (engine 330, shaft (rotary shaft) 370, gear 360, and power is transmitted from the motor generator 320 in order to maintain a certain constant rotation speed. ) Is the torque to be output required to balance with the load torque received from.

Therefore, the target torque command T * is larger than the upper limit value (load abnormal torque upper limit) 23 of the load torque abnormality threshold acquired by the threshold value calculation unit 12 with respect to the torque command in the normal state, or the load torque abnormality threshold value. If it is smaller than the lower limit value (lower limit of load abnormal torque) 24, it can be determined that the load torque abnormality is detected and the power generation mechanism (engine 330, shaft 370, gear 360) ahead of the motor generator 320 is out of order. ..

Further, since there is a time of several seconds to several tens of seconds in the section (a) -2, it is possible to sufficiently perform the determination of the present invention.

FIG. 7 is a flowchart for performing an abnormality determination of the generator system 6.

When the power generation process of FIG. 7 is started, the inverter converter 230 and the engine control unit 210 check whether the motor generator 320 and the engine 330, which are power generation mechanisms, are in an operable state (step FC10). ..

Then, the motor generator 320 rotates and starts so as to follow the rotation speed command from the upper ECU 200 (step FC20). Next, it is determined whether or not the current state is a steady state that is not the power generation state section (b) and is not the transient state section (a) -1 as shown in FIG. 6, that is, whether it is the section (a) -2. (Step FC30).

Here, if the state check (step FC10) is negative, the engine 330 and the motor generator 320 of the power generation mechanism are not in the power generation capable state, and therefore stop without generating power. If the diagnosable determination (step FC30) is negative, it has not yet passed through the section (a) -2 which is the steady state of cranking, so it returns after the generator start (FC20) and determines again.

If there is no abnormality in the state check and the diagnostic possibility determination (step FC30) is positive, the threshold value calculation process for use in the power generation stop determination process is performed (step FC40).

Next, as a power generation enablement determination (step FC50), the target torque command T * calculated by the target torque calculation unit 11 is compared with the upper and lower limit values T_Max and T_Min of the load torque abnormality obtained by the threshold value calculation unit 12, and the target is obtained. It is determined whether or not the torque command T * is within the threshold range of the upper and lower limit values T_Max and T_Min. When the target torque command T * is within the threshold range of the upper and lower limit values T_Max and T_Min, the result is transmitted to the target torque correction unit 13 and the upper ECU 200. Then, power generation by the motor generator 320 and the engine 330 is started (step FC60), and is stopped after sufficient power is supplied to the battery 300.

If the target torque command T * calculated by the target torque calculation unit 11 is outside the range of the upper and lower limit values T_Max and T_Min obtained by the threshold value calculation unit 12, the load torque is abnormal, that is, the connection mechanism is abnormal. An alarm (step FC70) is transmitted to the upper ECU 200 and the operator to stop the motor generator 230.

As described above, according to the first embodiment of the present invention, the upper and lower threshold values which are the abnormality determination range of the load torque from the rotation speed command ω * output from the upper ECU 200, the engine temperature EN_Tmp, and the outside air temperature Out_Tmp. Is set, and it is determined whether or not the target torque command T * calculated by the target torque calculation unit 11 is within the set upper and lower limit threshold values, and whether or not it is abnormal.

Therefore, in a vehicle equipped with a power output device and a power generation device, it is determined whether or not the connection mechanism connecting the generator and the internal combustion engine is abnormal in the state before power generation by the internal combustion engine, and the power generation device is damaged. It is possible to realize a power generation system control device that can be suppressed.

(Example 2)
Next, Example 2 of the present invention will be described.

As for the overall configuration of the power generation system 6, since the first and second embodiments are equivalent, illustration and detailed description thereof will be omitted.

FIG. 8 is a block diagram of the control unit 1 in the second embodiment.

In FIG. 8, the target torque calculation unit 11 calculates the target torque command T * using the rotation speed command ω * shown in FIG. 2 and the rotation position θ calculated by the rotation position detecting means 41. In addition, it is determined whether cranking is in progress, and a cranking flag (Crank_Flag) is acquired.

The threshold value calculation unit 12 calculates the upper limit T_Max and the lower limit T_Min of the load torque threshold value using the target rotation speed ω *, the engine temperature En_Tmp, and the outside air temperature Out_Tmp.

Further, the threshold value calculation unit 12 learns the map by inputting the target torque command T * calculated by the target torque calculation unit 11 and the torque estimation value T'obtained by the torque estimation unit 31.

The abnormality diagnosis unit 18 determines the load torque abnormality using T_Max and T_Min, the target torque command T *, and the cranking determination result Crank_Flag, and acquires the determination result Gen_Flag.

The target torque correction unit 13 calculates the second target torque Tcor * using the first target torque T * and the power generation enable flag Gen_Flag output by the power generation availability determination unit 18. Using the second target torque Tcor *, the PWM control signal is invertered by the current command generation unit 14, three-phase / dq conversion 15, current control unit 16, dq / three-phase voltage commission conversion unit 17, and gate signal generation unit 19. It is sent to the converter circuit 230.

The torque estimation unit 31 has a d-axis voltage command Vd * and a q-axis voltage command Vq *, which are output from the current control unit 16 and are used to calculate a signal for driving the motor generator 320, and a three-phase / dq conversion unit. The estimated torque T'of the motor generator 320 is calculated using the d-axis current detection value Id, the q-axis current detection value Iq, and the rotation position θ calculated by the rotation position detection means 41 shown in FIG.

FIG. 9 is a block diagram of the threshold value calculation unit 12 in the second embodiment.

In FIG. 9, the threshold value calculation unit 12 has the same as the threshold value calculation unit 12 shown in FIG. 4, the low temperature load abnormal torque map 121, the normal temperature load abnormal torque map 122, and the high temperature load abnormal torque map 123. Be prepared. The threshold value calculation unit 12 shown in FIG. 9 further includes a load abnormality torque learning value calculation unit 124.

The load abnormality torque learning value calculation unit 124 in the threshold value calculation unit 12 shown in FIG. 9 has the target torque command T * obtained by the target torque calculation unit 11 shown in FIG. 8 and the torque estimation value T obtained by the torque estimation unit 31. Compare with', find the difference between each other, memorize the result and the number of times the difference exceeds a certain threshold, and if the number of times exceeds a certain number, the target torque command T * The load torque maps 121, 122, and 123 are updated with respect to the deviation from the estimated torque value T'.

This makes it possible to improve the accuracy of the load torque abnormality threshold value over time.

According to the second embodiment, the same effect as that of the first embodiment can be obtained, and the load abnormality torque maps 121, 122, and 123 are displayed according to the deviation between the target torque command T * and the estimated torque value T'. Since it is configured to be updated, the accuracy of abnormality diagnosis can be further improved.

As described above, according to the present invention, in the power generation system control device having the power output device and the power generation device, the generator operates the internal combustion engine at a constant rotation speed for a predetermined period in the state before the power generation by the internal combustion engine. By ranking and comparing the load torque received by the generator during cranking with the threshold torque including the engine, shaft, and gear that takes into account the engine water temperature and outside temperature, the connecting mechanism (shaft, gear, engine) other than the generator. It is possible to realize a power generation system control device that minimizes damage by determining the failure of the engine at an early stage.

The present invention can be applied not only to a power generation system control device mounted on a vehicle, but also to, for example, a power output device such as a ship and a power generation system control device equipped with the power generation device.
