Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention is engaged when the shift position is set to the drive position.That transmits the engine output torque.LuckH, or the clutch that is engaged during forward running or the starting clutchWhen it is in the transmission and the specified stop condition is metThe aboveThe engine restarts the vehicle, which automatically stops the engine and the oil pump for the transmission, and restarts the automatically stopped engine and the oil pump when a predetermined restart condition is satisfied. Time control device.
[0002]
[Prior art]
Conventionally, a vehicle has been proposed that is configured to automatically stop the engine when a predetermined stop condition is satisfied while traveling and to save fuel, reduce exhaust emission, or reduce noise. It has already been put into practical use (for example, JP-A-8-14076).
[0003]
In such a vehicle, when a predetermined stop condition is satisfied and the engine is automatically stopped, the oil pump for transmission is also automatically stopped. On the other hand, when a predetermined restart condition such as when the driver steps on the accelerator pedal is satisfied, the oil pump is restarted when the engine that has been automatically stopped is restarted.
[0004]
  However, if the automatic transmission is a hydraulic automatic transmission, when the engine stops, the oil pump connected to the engine also stops as described above.ToThe supplied oil will also escape from the oil passage, and the oil pressure will drop. For this reason, when the engine is restarted, the forward clutch to be engaged during the forward travel is also in a state where the engaged state has been released.
[0005]
In this case, if the forward clutch is not immediately engaged when the engine is restarted, the accelerator pedal is depressed in a neutral state, and the forward clutch is engaged when the engine is blown up. Engagement shock may occur.
[0006]
Therefore, in order to prevent such a situation from occurring, in the vehicle according to the Japanese Patent Laid-Open No. 8-14076, the functions of a large accumulator and a check valve are required from when the engine is automatically stopped until it is restarted. This proposes a technique for maintaining the forward clutch in the engaged state.
[0007]
In JP-A-9-39613, the engine is not stopped completely, but only the fuel supply to the engine is stopped, the motor generator is driven, and the engine is maintained at an idling rotational speed. , We have proposed a technology that considers the oil pump not to stop.
[0008]
[Problems to be solved by the invention]
However, the technique of maintaining the forward clutch in the engaged state even when the engine is stopped by incorporating a large accumulator and a check valve, as in the technique proposed in Japanese Patent Laid-Open No. 8-14076. For example, the accumulator and the check valve are not used when the drain performance deteriorates when shifting from the D (drive) position to the N (neutral) position, that is, the release speed of the forward clutch is slow, the hydraulic control device is enlarged, etc. It was inevitable that a new harmful effect would occur due to the installation.
[0009]
Further, the technique of maintaining the engine at the idling rotational speed by the motor generator as in the technique proposed in Japanese Patent Laid-Open No. 9-39613 needs to drive the motor generator, although the fuel efficiency can be improved. Therefore, power consumption of the battery is remarkable, and there is a problem that it is necessary to increase the size (capacity) of the battery in order to ensure reliability.
[0010]
  The present invention has been made in view of such a conventional problem, and is engaged at the time of engine restart without causing any new problems such as deterioration of drain performance or enlargement of a hydraulic control device or a battery. Gearbox to be doneNo kuIt is an object of the present invention to provide a control device for restarting a vehicle that can make hydraulic characteristics to the latch appropriate and can achieve both prevention of engagement shock and ensuring responsiveness. .

  In addition, here"“Latch” refers to a clutch that is engaged when the shift position is set to the drive position. For example, in a stepped automatic transmission, it corresponds to a so-called “forward clutch”. In the case of a manual transmission with an automatic clutch, the "automatic clutch"In this invention,Corresponds to “latch”.
[0013]
  Also, here is "rapid pressure increase control",LuckToWhen oil is supplied, control is performed so that the oil supply speed (hydraulic pressure increase) is higher than that during normal supply.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0028]
  In the present embodiment, in the vehicle drive system as shown in FIG. 4, the engine is automatically stopped when a predetermined stop condition is satisfied, and the engine that is automatically stopped when a predetermined restart condition is satisfied. I'm trying to restart it. When the engine stops, the oil pump stops and the automatic transmission forward clutch (or start clutch) starts.H)Therefore, it is necessary to engage the forward clutch as soon as possible when the engine is restarted. This is to prevent the engine from blowing up in a neutral state as described above, and to quickly prepare the vehicle for starting.
[0029]
Therefore, in the present embodiment, rapid pressure increase control (described later in detail) is performed at the initial stage of oil supply to the forward (start) clutch. However, unless this rapid pressure increase control is appropriately performed, the forward clutch Since the engagement shock occurs, the present invention is applied so that the rapid pressure increase control can be always performed in an optimum manner according to the situation at that time.

It is connected through. An engine starter may be provided separately from the motor generator 3, and the starter and the motor generator 3 may be used together when starting the engine, or the starter may be used exclusively at extremely low temperatures.
[0031]
The speed reduction mechanism R is a planetary gear type, includes a sun gear 33, a carrier 34, and a ring gear 35, and is incorporated between the motor generator 3 and the clutch 28 via the brake 31 and the one-way clutch 32.

The automatic transmission 2 is provided with a known forward clutch C1 that is engaged during forward travel, a reverse clutch C2 that is engaged during reverse travel, and the like. Reference numeral 4 denotes an inverter electrically connected to the motor generator 3. This inverter 4 changes the rotation speed of the motor generator 3 by changing the supply of electric energy from the battery 5 as a power source to the motor generator 3 by switching. Further, switching is performed so that electric energy is charged from the motor generator 3 to the battery 5.
[0033]
  Reference numeral 7 denotes a clutch 26.28 is a controller for performing intermittent control of 8 and switching control of the inverter 4. A shift position sensor 4 that detects the signal of the switch 40 in the automatic stop traveling mode (eco-run mode) and the position of the shift position of the shift lever 44 is sent to the controller 7.6 signals, etc.Is entered. The arrow lines in the figure indicate each signal line. The control 7 is linked to an ECU (electronic control unit) 80 that controls the engine, the automatic transmission, and the like.

[0039]
On the other hand, a brake B0 that selectively stops the rotation of the sun gear 133 is provided. Further, a ring gear 134 that is an output element of the auxiliary transmission unit 112 is connected to an intermediate shaft 135 that is an input element of the main transmission unit 113.
[0040]
In the state where the clutch C0 or the one-way clutch F0 is engaged, the sub-transmission unit 112 rotates as a whole with the planetary gear mechanism 131, so that the intermediate shaft 135 rotates at the same speed as the input shaft 130. In the state where the brake B0 is engaged and the rotation of the sun gear 133 is stopped, the ring gear 134 is accelerated with respect to the input shaft 130 and rotates forward. That is, the sub-transmission unit 112 can set the two-stage switching between high and low.

A one-way clutch F1 and a brake B2 are arranged in series between the sun gears 141 and 151 and the casing 171. One-way clutch F1 has sun gears 141 and 151 rotating in reverse
They are engaged when attempting to roll (rotation in the direction opposite to the rotation direction of the input shaft 135).
[0046]
A brake B 3 is provided between the carrier 142 of the first planetary gear mechanism 140 and the casing 171. A brake B 4 and a one-way clutch F 2 are arranged in parallel between the casing 171 as elements for stopping the rotation of the ring gear 163 of the third planetary gear mechanism 160. The one-way clutch F2 is engaged when the ring gear 163 tries to reversely rotate.
[0047]
In the automatic transmission 2 described above, it is possible to eventually perform a shift of one reverse speed and five forward speeds.
[0048]

[0051]
“P (Parking)”, “R (Reverse)”, “N (Neutral)”, “D (Drive)” are arranged in order from the top (front side), and the manual “4” is on the right of “D”. The manuals “3”, “2”, and “L (low)” are arranged in that order from the bottom (front side). When the shift lever is moved to “4”, “3”, “2” in the manual, the automatic transmission is fixed to the fourth speed (4th), third speed (3rd), and second speed (2nd).
[0052]
Returning to FIG. 5, the solenoid valves S1, S2, S3, S4, SLN, SLT, and SLU in the hydraulic control device 75 are used by the ECU (electronic control) to engage or release each clutch and brake (friction engagement device).

And a signal to the ABS actuator).
[0057]
Next, a configuration for engaging the forward clutch C1 in the automatic transmission 2 will be described with reference to FIG.
[0058]
FIG. 9 is a hydraulic circuit diagram showing a main part of a configuration in which the forward clutch C1 is engaged in the hydraulic control device 75 of the automatic transmission.
[0059]
The primary regulator valve 50 is controlled by a line pressure control solenoid 52 and regulates the original pressure generated by the oil pump 19 to the line pressure PL. This line pressure PL is guided to the manual valve 54. The manual valve 54 is mechanically connected to the shift lever 44. Here, the line pressure PL is communicated to the forward clutch C1 side when the forward position, for example, the D position or the manual position 1st, 2nd, etc. is selected. Let
[0060]
A large orifice 56 and a switching valve 58 are interposed between the manual valve 54 and the forward clutch C1. The switching valve 58 is controlled by a solenoid 60, and is opened only while a rapid pressure increase control command, which will be described later, is issued. The oil that has passed through the large orifice 56 is guided to the forward clutch C1, and the others are maintained in the shut-off state. To do.
[0061]
The check ball 62 and the small orifice 64 are incorporated in parallel so as to bypass the switching valve 58. When the switching valve 58 is shut off by the solenoid 60 (normal time), the oil that has passed through the large orifice 56 is Furthermore, the forward clutch C1 is reached via the small orifice 64. The check ball 62 functions so that the drain is smoothly performed when the hydraulic pressure of the forward clutch C1 is drained.
[0062]
An accumulator 70 is disposed in an oil passage 66 between the switching valve 58 and the forward clutch C1 via an orifice 68. The accumulator 70 includes a piston 72 and a spring 74, and functions to maintain a predetermined hydraulic pressure determined by the spring 74 for a while when oil is supplied to the forward clutch C1, and the engagement of the forward clutch C1 is completed. Reduce the shock that occurs at times.
[0063]
Next, the operation of this embodiment will be described.
[0064]
When the engine is started, the electromagnetic clutch 26 is in a connected state, and the motor generator 3 is driven to start the engine. At this time, when the brake 31 is turned on and the clutch 32 is turned off, the rotation of the motor generator 3 is decelerated and transmitted from the sun gear 33 side of the speed reduction mechanism R to the carrier 34 side. Thereby, even if the capacity of the motor generator 3 and the inverter 4 is reduced, the driving force necessary for cranking the engine 1 can be secured. After the engine 1 is started, the motor generator 3 functions as a generator, and stores electric energy in the battery 5 when the vehicle is braked, for example. When the engine is started, the controller 7 detects the rotation speed of the motor generator 3, and outputs a switching signal to the inverter 4 so that the rotation of the motor generator 3 becomes a torque and a rotation speed necessary for starting the engine 1. For example, if the air conditioner switch signal is on when the engine is started, a larger torque is required than when the air conditioner is off. Therefore, the controller 7 outputs a switching signal so that the motor generator 3 can rotate at a large torque and rotational speed. Output.
[0065]
When a predetermined engine stop condition is satisfied in a state where the eco-run mode signal is on, the controller 7 outputs a signal for cutting off the fuel supply to the engine 1 to stop the engine. The eco-run mode signal is input to the controller 7 when the driver presses the eco-run switch 42 provided in the vehicle interior. Examples of the engine stop condition in the eco-run mode include “vehicle speed is zero”, “accelerator off”, “brake on”, and “charge capacity of battery 5 is a predetermined value or more”.
[0066]
When the automatic stop is not performed in relation to the shift position, the engine stop condition is, for example, the condition “the position of the shift lever 44 is D” or “the position of the shift lever 44 is“ The condition “N” or “P” (non-driving position) may be set.
[0067]
When the engine 1 is automatically stopped in the eco-run mode, the controller 7 outputs a disconnection control signal to the electromagnetic clutch 26, and the pulley 22 and the engine 1 are in a power non-transmission state. On the other hand, since the air conditioner and the power steering are desired to be operated even when the engine 1 is stopped, the controller 7 is connected to the inverter 4 so that the motor generator 3 rotates with a torque that takes into account the load of the power steering pump and the air conditioner compressor. Corresponding switching signals are output.
[0068]
At this time, the brake 31 is turned off, the clutch 32 is turned on, and the electromagnetic clutch 26 is turned off. By setting it as such a state, the motor generator 3 and the pulley 23 will be in a direct connection state, and it can ensure the rotational speed required to drive the auxiliary machinery 11 and 16 grade | etc.,. In order to use the motor generator 3 as a generator or drive the auxiliary machinery 11, 16, etc. while the engine is in operation, the brake 31 is turned off, the clutch 32 is turned on, the electromagnetic The clutch 26 is kept on. By doing so, the motor generator 3 and the pulley 23 are directly connected to each other, and the motor generator 3 and the auxiliary machines 1 and 16 are prevented from exceeding the allowable rotation speed even when the engine rotation speed increases. Can do. Even if the clutch 32 is replaced with a one-way clutch, substantially the same operation as described above can be obtained.
[0069]
Next, during the ND shift in relation to the restart of the engine 1, the forward clutch C1 is quickly engaged by appropriate rapid pressure increase control to ensure responsiveness and with a small engagement shock. The action to be combined will be described.
[0070]
When a sufficient amount of time has elapsed since the engine 1 was started, when shifting from the normal “N” position to the “D” position 1st, the oil passage of the line pressure system in the hydraulic control device (the above-described manual valve 54). The oil path is already filled with oil. Further, as is apparent from FIG. 6, in this state, the clutch C0 is in the engaged state, and therefore it is sufficient to supply oil only to the forward clutch C1. However, when the engine 1 is stopped and restarted to make a quick transition to the 1st position of the “D” position, the oil has drained from the line pressure system, and the clutch C0 must be engaged at the same time. Therefore, it is necessary to execute the “rapid pressure increase control” execution mode in which the oil is rapidly supplied particularly in the initial stage of oil supply in consideration of such circumstances.
[0071]
More specifically, it is assumed that when the shift position is the non-driving position, for example, the engine is restarted based on a condition such as a decrease in the charging capacity of the battery. At that time, the oil pump 19 starts rotating in FIG. 9 and the oil is supplied to the primary regulator valve 50 side. When a certain amount of time has passed in this state, the line pressure regulated by the primary regulator valve 50 is supplied to the manual valve 54.
[0072]
When the ND shift is performed in such a state, the forward clutch C1 can be engaged only by supplying oil to the oil passage after the manual valve 54, so that the quick pressure increase control only needs to be performed lightest ( Rather, strong rapid pressure increase control should be avoided because it induces rapid engagement of the forward clutch C1.
[0073]
However, when the engine 1 is restarted at the non-driving position and the shift position is changed from the non-driving position to the driving position before the hydraulic pressure is supplied to the manual valve 54, the rapid pressure increase control is further increased accordingly. Should be strengthened.
[0074]
Further, when the ND shift is executed simultaneously with the engine restart, the strongest rapid pressure-increasing control is executed because it starts from a state where there is no oil in the oil passage including the line pressure system. Should be.
[0075]
  That is, to summarize the above, “the oil by restarting the engine 1 (and the oil pump 19)Oil charge to the roadExecution state of rapid pressure-increasing control according to suitability (state)In other words, the oil supply speed at the time of executing the rapid pressure increase control, the execution time of the rapid pressure increase control, the control target pressure of the line pressure, or the restriction of the oil passagechange. "It turns out that.
[0076]
  In addition, "Level of oil filling to the oil passage"Match (condition)" means "oil to oilway etc.Filling degreeMatch (condition) "SayingIt can be changed.
[0077]
  In particular,"The degree of oil filling to the oilway "May be detected directly by a hydraulic sensor, or may be estimated and detected by an elapsed time after restart as in an example described later. It can also be estimated and detected by the integrated value of the engine speed (oil pump speed) after restart.
[0078]
FIG. 10 shows the hydraulic pressure supply characteristics of the forward clutch C1, the engine rotational speed NE, the rapid pressure increase control timing, and the turbine rotational speed when the shift position is changed from “N” to “D” and the engine is restarted at the same time. It is the figure which showed NT.
[0079]
In FIG. 10, the thin line indicates the case where the rapid pressure increase control is not executed, and the thick line indicates the case where it is executed. Tc and Tc ′ correspond to a period during which the clutch pack of the forward clutch C1 is packed, and Tac and Tac ′ correspond to a period during which the accumulator 70 is functioning. Further, a portion denoted by Tfast indicates a period (execution time) during which the rapid pressure increase control is being executed. This period Tfast qualitatively corresponds to a period during which a piston (not shown) of the forward clutch C1 packs a so-called clutch pack. This period Tfast is determined and controlled as follows.
[0080]
That is, in this embodiment, the elapsed time TST of the engine 1 and the oil pump 19 is divided into four regions to indirectly detect how much oil has been supplied, and the rapid pressure increase control is executed according to the elapsed time TST. The time Tfast is changed.
[0081]
(1) TST ≧ T1 Rapid pressure increase control execution time Tfast1
(2) T1> TST ≧ T2 Execution time Tfast2 of rapid pressure increase control
(3) T2> TST ≧ T3 Rapid pressure increase control execution time Tfast3
(4) T3> TST Rapid pressure increase control execution time Tfast4
[0082]
The time T1 substantially corresponds to the time for the oil to reach the manual valve 54, and is obtained by experiments. Times T2 and T3 are arbitrarily determined predetermined times shorter than this.
[0083]
Note that T1> T2> T3 and Tfast1 <Tfast2 <Tfast3 <Tfast4.
[0084]
For example, when the ND shift is executed before an extremely short time T3 including zero (simultaneous) has elapsed after the engine is restarted, the oil path is not almost filled with oil. Only the fastest Tfast4 is executed for the pressure increasing control. Further, after the engine is restarted, when the ND shift is executed before T2 longer than the above-described time T3 elapses, the engine is executed only for Tfast3 that is slightly shorter than the execution time Tfast4 of the rapid pressure increase control described above. .
[0085]
Similarly, the execution time of the rapid pressure increasing control is executed for a shorter Tfast2 until the time T1 when the time T2 or more passes and the manual valve 54 is reached.
[0086]
Then, when a time T1 corresponding to the time for the oil to reach the manual valve 54 has elapsed, an ND shift from a state where the oil is completely filled up to the manual valve 54 is obtained. The rapid pressure increase control is performed for the shortest execution time Tfast1 (including zero).
[0087]
To summarize the above, if the elapsed time from restarting the engine is long, a lot of oil is supplied to the oil passage, so a lot of oil is supplied to the oil passage, so rapid pressure increase control When the elapsed time is short (including zero), on the other hand, when the elapsed time is short, the execution time of the rapid pressure increase control is set longer.
[0088]
In addition to changing the execution time of the rapid pressure increase control, a means such as setting the control target pressure of the line pressure higher or loosening the throttle of the oil passage may be used.
[0089]
As is apparent from the display of FIG. 10, the start timing Ts of the rapid pressure increase control is set when the engine rotational speed (= the rotational speed of the oil pump 19) NE becomes a predetermined value NE1.
[0090]
If the rapid pressure-increasing control is started simultaneously with the engine restart command Tcom, the forward clutch C1 is sometimes engaged while the rapid pressure-increasing control is being executed due to the influence of this variation. It may be completed and a large engagement shock may occur. Therefore, avoiding immediately after restarting the engine with a large variation and setting the time Ts when the engine starts to rise slightly as the start timing of the rapid pressure increase control, the variation is small (stable) regardless of the driving environment. Oil supply control can be realized.
[0091]
Next, a specific control flow according to the present embodiment will be described with reference to FIGS.
[0092]
First, FIG. 1 will be described.
[0093]
FIG. 1 is a control flow when the engine automatically stops only at the “N” position. Therefore, the engine is restarted whenever there is an ND shift.
[0094]
In step 320, various input signals are processed. In step 330, it is determined whether or not the engine is currently stopped at the “N” position, and it is determined whether or not the engine is stopped by the engine automatic stop control. If the engine is stopped at the “N” position, the process proceeds to step 340. If the engine is not stopped at the “N” position, the process proceeds to step 370.
[0095]
In step 340, it is determined whether or not an engine restart condition is satisfied at the “N” position. When a predetermined engine restart condition is satisfied, the engine automatic stop is immediately stopped and the engine restart process is executed. When starting the engine, it is assumed that the early cylinder discrimination is performed before starting (step 350).
[0096]
In step 360, the counting of the elapsed time TST after the engine is restarted is started.
[0097]
  In the present embodiment, a system that supplies hydraulic pressure by executing rapid pressure increase control for the forward clutch C1 when an ND shift is performed is adopted, so in step 370, the ND shift is executed. Whether or notDetermine whether.Whether the shift has been changedThe judgment isWhat is necessary is just to carry out by the shift position sensor 46 installed beside the shift lever. If there is no ND shift, the process returns as it is. If there is an ND shift, the process proceeds to step 380, and an elapsed time TST after the engine is restarted is checked.
[0098]
In step 390, the execution time of the rapid pressure increase control (Tfast1, Tfast2, Tfast3) every elapsed time (TST ≧ T1, T> TST ≧ T2, T2> TST ≧ T3, T3> TST) after the engine is restarted. , Tfast4) are changed and set, respectively. In this embodiment, the execution mode of the rapid pressure increase control is changed by dividing into the four types of times described above, but is not particularly limited to this, and the rapid pressure increase control corresponding to that is divided more finely. Execution time may be set.
[0099]
In step 400, ND control (engagement of the forward clutch C1) is executed by performing rapid pressure increase control for a set time.
[0100]
Next, FIG. 2 and FIG. 3 will be described.
[0101]
FIGS. 2 and 3 are control flows when the engine automatically stops even when the shift position is “D”. Therefore, the engine does not necessarily restart even if there is an ND shift. 2 and 3 are executed in parallel.
[0102]
Steps 520 to 560 in FIG. 2 are steps for counting the elapsed time TST from the restart when there is an automatic stop → restart at the “N” position, and are the same as steps 320 to 360 in FIG. Is omitted.
[0103]
Next, FIG. 3 will be described.
[0104]
After performing various input signals in step 620, it is determined in step 630 whether or not there is an ND shift. In this flow, even if the shift position is “D”, the engine is automatically stopped. Therefore, even if the engine is shifted to the “D” position, the engine is not immediately forcibly started, and the condition that the engine is set to the “D” position. The engine restarts when a predetermined restart condition not included is satisfied.
[0105]
If there is an ND shift, the process proceeds to step 640 to determine whether or not the engine is automatically stopped. The determination during the engine automatic stop here is because the engine may have already been restarted when the shift position is at the “N” position.
[0106]
If the engine is automatically stopped in step 640, the process proceeds to step 650, and the restart condition is determined. If the engine restart condition is satisfied, the routine proceeds to step 660, where the early cylinder discrimination is performed and the engine restart process is performed.
[0107]
If the engine is not automatically stopped in step 640, the process proceeds to step 670, and it is determined whether or not the engine restart condition is satisfied. If the engine restart condition is not satisfied, the process returns. If the restart condition is satisfied, the process proceeds to step 680.
[0108]
In step 680, an elapsed time TST from the restart of the engine obtained at that time by the control flow of FIG. 2 is checked.
[0109]
In step 690, the execution time Tfast of the rapid pressure increase control is changed and set in the same manner as described above according to the time TST after the engine is restarted.
[0110]
In step 700, the engagement control of the forward clutch C1 is performed by performing the rapid pressure increase control only for the set time.
[0111]
In Step 710, since the ND shift is not executed or the engine is stopped and the return condition is not satisfied, the hydraulic control of the forward clutch C1 is not executed.
[0112]
【The invention's effect】
  According to the present invention, when the shift position is changed from the non-drive position to the drive position, the execution state of the rapid pressure increase control isIn other words, the oil supply speed at the time of executing the rapid pressure increase control, the execution time of the rapid pressure increase control, the control target pressure of the line pressure, or the restriction of the oil passageTo the oil passage of the transmission by restarting the engine and oil pumpOil filling degreeOr by changing according to the elapsed time from restart of the engine and oil pump, at the time of engine restart without causing any new problems such as deterioration of drain performance or enlargement of hydraulic control device or battery Gearbox to be engagedThe clutch that is engaged when the shift position is set to the drive position and transmits the output torque of the engine, or the clutch that is engaged during forward traveling, or the starting clutchThe hydraulic characteristic to the latch can be made appropriate, and as a result, an excellent effect that both prevention of engagement shock and securing of responsiveness can be achieved.
