Below, the control system of motor involved in the present invention is described referring to figs. 1 through Figure 10.In addition, thus the control system of motor below in the embodiment of explanation is to obtain the control system of the described engine of the electric automobile that actuating force travels by engine.
＜embodiment 1 〉
The embodiment 1 of the control system of motor involved in the present invention is described referring to figs. 1 through the accompanying drawing of Fig. 4 at first.
Fig. 1 is the block diagram of control system of the motor of embodiment 1.Engine 10 possesses the stator coil (following referred to as coil) that produces rotating magnetic field by current flowing.Engine 10 is subject to the export-restriction of export-restriction control device 1 when the operating condition of regulation, launched machine control part 11 is controlled simultaneously.
Export-restriction control device 1 possesses: unit 6 is removed in operation range judging unit 2, the 1st duration of runs timer 3, export-restriction unit 4, export-restriction time timer 5 and export-restriction.
Which operation range running operation range judging unit 2 judges engine 10 in, as the parameter that is used for this operation range of judgement, to torque (amount relevant to output) and the rotating speed of export-restriction control device 1 input engine 10.
In embodiment 1, set as shown in Figure 2 the operation range of engine 10.In this Fig. 2, the longitudinal axis represents the torque of engine 10, and transverse axis represents the rotating speed of engine 10, and thick line represents the breakdown torque characteristic of engine 10.Engine 10 uses in the zone of the downside of the line of expression breakdown torque characteristic.In other words, the zone of the downside of the line of expression breakdown torque characteristic becomes the operation range of this engine 10.In addition, as like that clear and definite in Fig. 2 institute, breakdown torque until the rotation speed n 1 of regulation during be constant, stipulate rotation speed n 1 if surpass, be accompanied by the increase of rotating speed and slowly reduction.
The operation range of engine 10 is divided into 2 following zones: zone (below the be called continuous operation zone) C that occupies the downside of zone near the part of breakdown torque characteristic (below be called specified operation range of time) L and the specified operation range of Occupation time in the full rotation zone.
Continuous operation zone C is the operation range that makes engine 10 continuous operations when can remain in the temperature of the coil that makes engine 10 below the higher limit tmax (for example 180 ℃) of management temperature, as long as turn round in continuous operation zone C, the temperature of the coil of engine 10 just can not surpass higher limit tmax.In addition, as shown in Figure 4, the higher limit tmax of management temperature is set as the temperature of the low set point of temperature of allowable temperature of ratio engine 10.
On the other hand, if make engine 10 continuous operations will make the temperature of the coil of engine 10 surpass higher limit tmax in specified operation range L of time, therefore, be the operation range that has limited continuous operation time.
In the present embodiment 1, specified operation range L of time can be described as the 1st relatively large operation range of heating of coil, and continuous operation zone C can be described as the 2nd operation range of the heating less of coil.
Described operation range judging unit 2 is that torque (amount relevant to the output of engine 10) and rotating speed judge it is which operation range in specified operation range L of time and the regional C of continuous operation turns round based on the parameter of operating condition of the engine 10 of expression current point in time.
The duration of runs that the 1st duration of runs, timer 3 detected engines 10 continuous operation in specified operation range L of time namely the 1st the duration of runs T1.The 1st the duration of runs timer 3 consisted of by counter, engine 10 be in turn round in specified operation range L of time during, count value that will be corresponding with predefined the 1st stipulated time a1 is as initial value, subtract counting with the 1st fixing speed from this initial value, transfer in operation point, thereby engine 10 take described initial value as the upper limit, adds counting with the 2nd fixing speed during continuous operation zone C running.
Export-restriction unit 4 in the situation that the 1st the duration of runs timer 3 detected the 1st the duration of runs T1 surpass described the 1st stipulated time a1, the operation range of engine 10 is limited in continuous operation zone C.In this embodiment 1, in the situation that the 1st the duration of runs T1 surpass the 1st stipulated time a1, with the torque limit of engine 10 upper limit torque at continuous operation zone C.
The 1st stipulated time a1 sets based on the data of the experiment of implementing in advance, is set as in the situation that make time till the temperature of engine 10 coil of continuous operation engine 10 in specified operation range L of time reaches higher limit tmax.In this embodiment 1, the 1st stipulated time a1 is following sets: make the running (for example operation point X2 in Fig. 2) under the breakdown torque Trq1 of the low rotation speed area (rotation speed n in Fig. 2 is below 1) of running from the specified operation range L of state (the operation point X1 in Fig. 2) time that is passed to that travels on smooth road with maximal rate Vmax of engine 10 among continuous operation zone C, based in the situation that the rate of rise in temperature of the coil of this operation point continuous operation set.That is, the rate of rise in temperature under the stringent condition that the most easily rises based on the temperature in specified operation range L interior loop of time of the 1st stipulated time a1 is set.
Namely, if make the continuous operation time in specified operation range L of the time of engine 10 surpass the 1st stipulated time a1, arrive the situation of higher limit tmax due to the temperature of the coil that engine 10 may occur, therefore, this moment, the operation range with engine 10 was limited in continuous operation zone C, the temperature that can prevent thus above coil rises, and can reduce the temperature of coil.
Duration export-restriction time T 2 when the operation range that export-restriction time timer 5 detects engine 10 is limited in continuous operation zone C.
Export-restriction is removed unit 6 in the situation that surpass the 2nd stipulated time a2 by the detected export-restriction time T 2 of export-restriction time timer 5, lifts restrictions in the restriction of the operation range of continuous operation zone C.
The 2nd stipulated time a2 sets based on the experimental data of implementing in advance, as shown in Figure 4, in the situation that the running that the temperature of the coil of engine 10 arrives under the state of higher limit tmax engine 10 is limited in continuous operation zone C, the 2nd stipulated time a2 is set as from this restriction begins until the temperature of coil is reduced to the needed time of set point of temperature t1.In this embodiment 1, described set point of temperature t1 is made as the saturation temperature of the coil when travelling on smooth road with maximal rate Vmax in the C of continuous operation zone.In addition, the 1st stipulated time a1 and the 2nd stipulated time a2 can also be set as same time (a1=a2).
In this embodiment 1, owing to making torque-limiting value when operation range is limited in continuous operation zone C become upper limit torque in continuous operation zone C, therefore, as shown in solid line in Fig. 4, the temperature of coil reduces slack-off, and the 2nd stipulated time a2 is set to the long time.But, if make torque-limiting value when operation range is limited in continuous operation zone C become torque value less than the upper limit torque in continuous operation zone C, as shown in double dot dash line in Fig. 4, therefore temperature underspeeds and accelerates, and the 2nd stipulated time a2 being set as the shorter time becomes possibility.That is, can correspondingly suitably set the 2nd stipulated time a2 with the size of torque-limiting value.
Next, the torque limit control of the engine 10 in embodiment 1 is described according to the flow chart of Fig. 3.Torque shown in the flow chart of Fig. 3 is controlled control routine and is repeatedly carried out by export-restriction control device 1.
At first, in step S101, obtain torque and rotational speed as the operation information of the current point in time of engine 10.
Next, advance to step S102, based on the torque and rotational speed of the engine 10 of obtaining at step S101, judge whether engine 10 just turns round in specified operation range L of time.
Result of determination in step S102 is "Yes" (in the situation that turning round in specified operation range L of time), advances to step S103, to consist of the 1st the duration of runs timer 3 counter carry out and count down.On the other hand, the result of determination in step S102 is "No" (in the situation that turning round in the C of continuous operation zone), advances to step S104, to consist of the 1st the duration of runs timer 3 described counter carry out and add counting.
Advance to step S105 from step S103 and step S104, the duration of runs of coming calculation engine 10 continuous operation in specified operation range L of time based on the count value of counter namely the 1st the duration of runs T1.
Next, advance to step S106, whether judgement T1 the 1st duration of runs has surpassed the 1st stipulated time a1.
In the situation that the result of determination of step S106 is that (T1≤a1), advance to step S107 does not carry out torque limit to engine 10 and turns round "No", and advances to and return.That is, until the continuous operation time in specified operation range L of time surpasses the 1st stipulated time a1, all allow the running in specified operation range L of time.
In the situation that the result of determination in step S106 is that (T1＞a1), advance to step S108 is limited in the running of engine 10 in continuous operation zone C "Yes".In addition, in the present embodiment 1, with the upper limit torque of torque limit in continuous operation zone C of engine 10.
Next, advance to step S109, take initial value as limit to consist of the 1st the duration of runs timer 3 counter carry out and add counting.And then, advance to step S110, calculate the elapsed time of beginning after torque limit, be that the operation range of engine 10 is limited in the duration in continuous operation zone C, namely export-restriction time T 2 based on the count value of described counter.In this embodiment 1, the counter of formation timer the 1st duration of runs 3 doubles as the counter (export-restriction time timer 5) that calculates export-restriction time T 2.
Next, advance to step S111, judge whether export-restriction time T 2 has surpassed the 2nd stipulated time a2.
In the situation that the result of determination of step S111 is that (T2≤a2), return to step S018 continues torque limit to "No".
In the situation that the result of determination of step S111 is that (T2＞a2), advance to step S112 removes torque limit to "Yes", advances to and returns.
Control system according to the motor of the present embodiment 1, in the situation that surpassed the 1st stipulated time a1 the duration of runs of the engine 10 in specified operation range L of time, the operation range of engine 10 is limited in continuous operation zone C, with the upper limit torque of torque limit at continuous operation zone C, therefore, the temperature of the coil of engine 10 can be suppressed at below the higher limit tmax of management temperature.
In addition, owing to removing torque limit in the situation that surpassed the 2nd stipulated time a2 the duration of runs of the engine 10 under above-mentioned torque limit, therefore, can be reduced in the temperature of the coil of engine 10 time point of lower temperature, remove torque limit, therefore, can when suppressing coil overheated, suppress the situation of the operation range of excessive limiting engine 10.
And, owing to can be not carrying out the temperature treatment of engine 10 with the temperature sensor of the temperature of the coil that detects engine 10, therefore can cut down number of components.In addition, due to the running resume that yet do not need to store engine 10, do not need the temperature of the coil etc. of estimated engine 10, the control system that therefore is used for the temperature treatment of engine 10 can be not complicated, and control system is oversimplified.
and then, engine 10 be in specified operation range L of time running during, take the count value suitable with the 1st stipulated time a1 as initial value, count down from this initial value, engine 10 be in continuous operation zone C running during add counting take described initial value as the upper limit, by such counter consist of the 1st the duration of runs timer 3, even therefore engine 10 according in the situation that the mode of moving between specified operation range L of time and continuous operation zone C turn round, also can consider duration of runs in the larger specified operation range L of time of the heating of coil by use, with the count value after duration of runs in the less continuous operation of the heating of coil zone C, make count value become the value relevant to the degree of heat of coil.And, due to when this count value arrives " 0 " corresponding with the 1st stipulated time a1, the operation range of engine 10 is limited in continuous operation zone C, therefore, even engine 10 according in the situation that the mode of moving between specified operation range L of time and continuous operation zone C turn round, also can suppress the overheated of coil infalliblely, and the temperature of coil is become below the higher limit tmax of management temperature.
in addition, because the 1st stipulated time a1 is based on the rate of rise in temperature of the coil of the running (in the situation that under stringent condition that the temperature of specified operation range L interior loop of time the most easily rises) under the breakdown torque Trq1 of the running of engine 10 low rotation speed area (below Fig. 2 medium speed n1) from the state that travels on smooth road among continuous operation zone C with maximal rate Vmax is passed to specified operation range L of time set, therefore, in the situation that in specified operation range L of time, the output point lower than breakdown torque Trq1 turns round, also can suppress the overheated of coil infalliblely, the temperature of coil is become below the higher limit tmax of management temperature.This be because, in specified operation range L of time than breakdown torque Trq1 the rate of rise in temperature of the coil the during running of low output point than breakdown torque Trq1 under the rate of rise in temperature of coil during running slow.
＜embodiment 2 〉
Next, the embodiment 2 of the control system of motor involved in the present invention is described to the accompanying drawing of Figure 10 with reference to Fig. 5.In addition, about the formation of the control system of the motor in embodiment 2, due to identical with the situation of embodiment 1, therefore quote the block diagram of Fig. 1 and description thereof is omitted.
The difference of the control system of the motor of embodiment 2 and embodiment 1 is, in embodiment 2, as Fig. 5, shown in Figure 7, specified operation range L of time further is subdivided into 2 operation range this point.Describe in detail, specified operation range L of the time in embodiment 2 is subdivided in specified operation range L of time output in high output area near the breakdown torque characteristic (below be called the a-quadrant) and specified operation range L of time lower than the zone of a-quadrant (below be called B zone).In this case, because the a-quadrant is positioned at high outlet side with respect to the B zone, therefore, can say that the a-quadrant is the zone larger than the coil heating in B zone.In addition, the continuous operation zone C in the zone of the continuous operation in embodiment 2 C (following sometimes also referred to as the C zone) and embodiment 1 sets in the same manner.
And, in this embodiment 2, in the situation that the continuous operation time in the a-quadrant of engine 10 surpasses the 3rd stipulated time a3, the running of engine 10 is limited in the B zone, with the upper limit torque of torque limit in the B zone.
In addition, continuous operation time in the situation that specified operation range L of the time of engine 10 in (comprise a-quadrant and B zone both) surpasses the 4th stipulated time a4, the running of engine 10 is limited in the C zone, with the upper limit torque of torque limit in the C zone.
At this, the 3rd stipulated time a3 and the 4th stipulated time a4 set based on the experimental data of implementing in advance.
The establishing method of the 1st stipulated time a1 in the establishing method of the 3rd stipulated time a3 and embodiment 1 is identical, all with the running of engine 10 running (for example operation point X4 in Fig. 5) under the breakdown torque Trq1 that travels on state (the operation point X3 of Fig. 5) on the smooth road low rotation speed area (below Fig. 5 medium speed n1) in being passed to the a-quadrant among continuous operation zone C with maximal rate Vmax, based in the situation that under this operation point the rate of rise in temperature of the coil of continuous operation set.As shown in Figure 6, the vehicle that travels on smooth road with maximal rate Vmax is suitable with the situation of travelling on the upward trend of abrupt slope (gradient α %).
The 4th stipulated time a3 is the running (for example operation point X5 in Fig. 7) that the running of engine 10 is passed to from travel on state (the operation point X3 of Fig. 7) on smooth road with maximal rate Vmax among continuous operation zone C under the breakdown torque Trq2 of the low rotation speed area (below Fig. 2 medium speed n1) in the B zone, based in the situation that under this operation point the rate of rise in temperature of the coil of continuous operation set.As shown in Figure 8, the vehicle that travels on smooth road with maximal rate Vmax with travel in gradient less than the suitable (β＜α) of the state of the upward trend of the gradient of the β % of α %.
So set, the 4th stipulated time a4 sets than the long (a4＞a3) of the 3rd stipulated time a.In addition, in this embodiment 2, the 4th stipulated time a4 is made as 2 times (a4=a3 * 2) of the 3rd stipulated time a3.
Next, the torque limit control of the engine 10 in embodiment 2 is described according to the flow chart of Fig. 9.Torque shown in the flow chart of Fig. 9 is controlled control routine and is repeatedly carried out by export-restriction control device 1.
At first, in step S201, obtain the rotating speed of torque as the operation information of the current point in time of engine 10.
Next, advance to step S202, based on the torque and rotational speed of the engine 10 of obtaining at step S201, judge whether running in specified operation range L of time (in a-quadrant and B zone zone) arbitrarily of engine 10.
Result of determination in step S202 is "Yes" (in the situation that turning round in specified operation range L of time), advances to step S203, to consist of the 1st the duration of runs timer 3 counter carry out and count down.On the other hand, the result of determination in step S202 is "No" (in the situation that turning round in the C of continuous operation zone), advances to step S204, to consist of the 1st the duration of runs timer 3 described counter carry out and add counting.
Advance to step S205 from step S203 and step S204, the duration of runs of coming calculation engine 10 continuous operation in specified operation range L of time based on the count value of counter namely the 1st the duration of runs T1, differentiate the 1st the duration of runs T1 be less than the 3rd stipulated time a3 or more than the 3rd stipulated time a3 and less than the 4th stipulated time a4 or more than the 4th stipulated time a4.
In the situation that the 1st the duration of runs T1 less than the 3rd stipulated time a3 (step S206), advance to step S207 from step S206, engine 10 torque-limiting ground are not turned round, advance to and return.
In the situation that the 1st the duration of runs T1 be more than the 3rd stipulated time a3 and less than the 4th stipulated time a4 (step S208), advance to step S209 from step S208, the running of engine 10 is limited in the B zone, advance to and return.That is, engine 10 in the situation that the continuous operation time of a-quadrant is more than the 3rd stipulated time a3 and less than the 4th stipulated time a4, the running of engine 10 is limited in the B zone.In addition, in the nature of things, engine 10 in the situation that the continuous operation time in the B zone is that more than the 3rd stipulated time a3 and less than the 4th stipulated time a4, also the running with engine 10 is limited in the B zone.In addition, in this embodiment 2, with the torque limit of engine 10 upper limit torque in the B zone.
In the situation that the 1st the duration of runs T1 be more than the 4th stipulated time a4 (step S210), advance to step S211 from step S210, the running of engine 10 is limited in C zone (continuous operation zone C).In addition, the 1st the duration of runs T1 become the 4th stipulated time a4 to go forward, due to the processing that must want execution in step S208, S209, therefore, at the time point that advances to step S210, engine 10 is inevitable in B zone running.In addition, in this embodiment 2, with the upper limit torque of torque limit in continuous operation zone C of engine 10.
Next, advance to step S212, take initial value as limit, to consist of the 1st the duration of runs timer 3 counter carry out and add counting.Further, advance to step S213, calculate elapsed time of beginning torque limit is risen in C zone, be the duration that the operation range of engine 10 is limited in the C zone based on the count value of described counter, namely export-restriction time T 2.In this embodiment 2, the counter of formation timer the 1st duration of runs 3 doubles as the counter (export-restriction time timer 5) that calculates export-restriction time T 2.
Next, advance to step S214, judge whether export-restriction time T 2 surpasses the 2nd stipulated time a2.Because the establishing method of the 2nd stipulated time a2 is identical with the situation of embodiment 1, therefore description thereof is omitted.In addition, the 4th stipulated time a4 also can set to get identical with the 2nd stipulated time a2 (a4=a2).
In the situation that step S214 in result of determination be that (T2≤a2), return to step S211 continues the torque limit of torque limit in the upper limit torque in C zone "No".
In the situation that the result of determination in step S214 is that (T2＞a2), advance to step S215 removes torque limit to "Yes", advances to and returns.
According to the control system of the motor of this embodiment 2, except the effect of playing aforesaid embodiment 1, effect, also have following effect, effect.
In embodiment 2, specified operation range L of time is subdivided into the heating B zone less than the a-quadrant of the larger a-quadrant of the heating of coil and coil, due to engine 10 in the situation that the continuous operation of a-quadrant causes applying the restriction of operation range, not immediately with torque limit in the operation range in C zone, but torque limit is being limited in again the operation range in C zone after the operation range in B zone, therefore, during at the a-quadrant continuous operation, can suppress excessively to limit the situation of operation range at engine 10.In addition, can make the continuous operation time in the heating of coil smaller B zone longer, can suppress the situation of the operation range of excessive limiting engine 10.
Next, be described more specifically the export-restriction of the motor in embodiment 2 with reference to the sequential chart of Figure 10.In addition, in the example of this sequential chart, the 2nd stipulated time a2 and the 4th stipulated time a4 are made as the identical time, and they are made as the time of 2 times (a2=a4=a3 * 2) of the 3rd stipulated time a3.
Figure 10 (A) illustrates following situation: make parking at the vehicle launch of the upward trend of gradient β, when travelling on this upward trend, make engine 10 in B zone running, having stepped on the needed time of this upward trend is stipulated time a4 (i.e. the 4th stipulated time a4), the transfer of travelling from this upward trend to smooth road.In this case, owing to not carrying out export-restriction until passed through the 3rd stipulated time a3 from beginning to travel, therefore allow the running in the B zone.Afterwards, from having passed through the 3rd stipulated time a3 until passed through the 4th stipulated time a4 during, the operation range of engine 10 is restricted to the running in the B zone, torque is restricted to the upper limit torque in B zone.That is, from beginning to travel until passed through the 4th stipulated time a4 during, engine 10 is allowed the running in the B zone.Then, stepping on when upward trend, becoming the 4th stipulated time a4 in the duration of runs in B zone, the operation range of engine 10 is limited in the C zone, and torque is limited in the upper limit torque in C zone.Its result, the temperature of the coil of engine 10 (winding) began to reduce before the management temperature reaches higher limit tmax.
In addition, the 1st timer duration of runs (export-restriction time timer) counts down in the running in B zone, after being limited in the C zone until initial value adds counting.
Then, when the 1st duration of runs, timer returned to initial value (when having passed through the 2nd stipulated time a2), remove torque limit, engine 10 becomes the running that does not have under torque limit.
Figure 10 (B) illustrates following situation: make the vehicle launch that stops on smooth road, in the time of on travelling on this smooth road, make engine 10 with the full torque running of a-quadrant, before arriving the 3rd stipulated time a3 the duration of runs of a-quadrant, be passed to the running in the C zone.In this case, engine 10 is not subject in fact torque limit ground running.And the temperature of the coil of engine 10 (winding) remains on below the higher limit tmax of management temperature.
In addition, the 1st timer duration of runs (export-restriction time timer) is until the operation point of engine 10 is passed to the C zone all counts down, after entering into the C zone until initial value adds counting.
Figure 10 (C) illustrates following situation: make engine 10 from the C zone with maximum (top) speed (the max speed Vmax) thus the state transitions of running travel to the upward trend of gradient β and make engine 10 be passed to the running in B zone, having stepped on the needed time of this upward trend is a4 (i.e. the 4th stipulated time a4), the transfer of travelling from this upward trend to smooth road.
Make engine 10 in the C zone with maximum (top) speed (the max speed Vmax) running during, do not carry out torque limit.Afterwards, thereby become the B zone even transfer to the upward trend operation range that makes engine 10 of travelling, the 3rd stipulated time a3 has been passed through in the running that remains in the B zone unchangeably, until also only the operation range of engine 10 is limited in the B zone through the 4th stipulated time a4, only with the upper limit torque of torque limit in the B zone.Then, having stepped on when upward trend just became for the 4th duration of runs in the duration of runs in B zone, and therefore, the operation range of engine 10 is limited in the C zone, and torque is limited in the upper limit torque in C zone.Its result, the temperature of the coil of engine 10 (winding) can not surpass the higher limit tmax of management temperature, begin to reduce before that.
In addition, the 1st timer duration of runs (export-restriction time timer) counts down in the running in B zone, with torque limit behind the C zone, until initial value adds counting.
Then, when the 1st duration of runs, timer returned to initial value (when having passed through the 2nd stipulated time a2), remove torque limit, engine 10 becomes the running that does not have under torque limit.
In the example of Figure 10 (C), when transferring to the running that does not have under torque limit, owing to making engine 10 in B zone running, therefore the 1st the duration of runs timer begin once again to count down.
