Japanese Patent Laid-Open No. 2000-74211 proposes a shift control device of a so-called shift-by-wire system that switches shift positions such as R, R (reverse), N (neutral), and D (drive).

Therefore, normally, both shift devices are set to be usable. In this case, if the shift operations of the two shift devices are different, there arises a problem that detection signals corresponding to the shift operations interfere with each other.

The present invention has been made in view of the above circumstances, and an object thereof is to prevent interference between a detection signal based on a shift operation of the first shift device and a detection signal based on a shift operation of the second shift device. An object of the present invention is to provide a shift control device for a transmission that can be avoided.

Even if the shift lever 31 is operated along the guide groove 32 to any of the R position, the D position, the − position, and the + position, if the operating force is released, the shift lever 31 is operated by the function of the detent mechanism (not shown). Each time, it is returned to the operation center position of the guide groove 32.

Further, the instrument panel 34 is provided with a manual cut switch 36 for switching between valid and invalid of a detection signal based on a shift operation of the second shift device 26.

In the vehicle according to the present embodiment, as an electronic control unit (ECU) that plays a role as the above-mentioned control system, an engine ECU ("E" that mainly controls the operation of the engine 2).
/ GECU ") 38 and a transmission ECU (" A / TECU ") 40 which mainly controls the A / T 6 described above. The ECUs 38 and 40 are electrically connected to each other through an in-vehicle network line.

The A / TECU 40 includes a detection signal from the first shift detection sensor 42 of the first shift device 22, and a second detection signal from the second shift detection sensor 42.
The detection signal of the second shift detection sensor 44 of the shift device 26 and the setting signal of the manual cut switch 36 are input. In addition, the A / TECU 40 has a driver door 2
Door switch 4 for detecting the open / closed state of the vehicle door including 4
The detection signal of 6 is input, and the detection signal of the collision detection sensor 48 that detects the collision of the vehicle is also input.

A microcomputer is used as the A / TECU 40, and is a read-only memory that stores programs necessary for various software processes related to the shift position switching of the A / T 6 and the automatic switching of each shift speed in the forward traveling position. (ROM), a central processing unit (CPU) that executes this program, a writable memory (RAM) that temporarily stores variables necessary for the program, and the like.

When the detection signal of the first shift detection sensor 42 and the detection signal of the second shift detection sensor 44 are input at the same time when the engine 2 is operating, the A / TECU 40 outputs the first shift detection sensor 42. The detection signal is prioritized, and the drive control of the motor 10 is performed based on the detection signal.

When the A / TECU 40 detects a vehicle collision based on the detection signal of the collision detection sensor 48 while the engine 2 is operating, it determines that the second shift device 26 is in the unsteady state, and the second The drive of the motor 10 based on the detection signal of the shift detection sensor 44 is prohibited. This is because the second shift device 26 provided on the driver's seat door 24 is operated when an abnormal external force is applied due to a vehicle collision.
May be damaged, and the reliability of the detection signal of the second shift detection sensor 44 may be deteriorated. In such a case, the use should be intentionally avoided.

When the A / TECU 40 detects the opening of the vehicle door based on the detection signal of the door switch 46 in the operating state of the engine 2, it determines that the second shift device 26 is in the unsteady state, and the second Shift detection sensor 44
The driving of the motor 10 based on the detection signal is prohibited. When the driver's seat door 24 is opened, the second shift device 26 also moves, the second shift device 26 moves away from the driver, the arrangement angle changes, and the shift lever 31 moves.
The visibility in the operating direction of the item will decrease. This is because if the second shift device 26 is operated to shift in this state, the second shift device 26 may be operated to a shift position different from the shift position intended by the driver, and the reliability of the shift operation may be reduced. .

Next, the shift control process executed by the A / TECU 40 will be described with reference to the flowchart of FIG. This process is a process that is repeatedly executed periodically at preset short time intervals.

When this processing is started, first, step 1
At 00, it is determined whether the driver's seat door 24 is open based on the detection signal of the door switch 46. If it is determined that the driver's seat door 24 is open, the process proceeds to step 150, and if it is determined that the driver's seat door 24 is not open, the process proceeds to step 110.

At step 110, it is judged based on the detection signal of the collision detection sensor 48 whether the vehicle has collided. If it is determined that the vehicle has collided, the process proceeds to step 15
When it is determined that the vehicle has not collided with 0, the routine proceeds to step 120.

In step 120, it is determined whether the second shift device 26 is invalidated based on whether the setting signal of the manual cut switch 36 is ON. If it is determined that the setting signal of the manual cut switch 36 is ON, the process proceeds to step 150, and if it is determined that the setting signal of the manual cut switch 36 is OFF, the process proceeds to step 130.

In step 130, both the first shift device 22 and the second shift device 26 are activated. As a result, the first operation based on the shift operation of the first shift device 22 is performed.
The detection signal of the shift detection sensor 42 is processed as valid, and the detection signal of the second shift detection sensor 44 based on the shift operation of the second shift device 26 is processed as valid.

In the next step 140, the first shift device 2
The detection signal based on the second shift operation is the second shift device 26.
Is prioritized with respect to the detection signal based on the shift operation. That is, the detection signal of the first shift detection sensor 42 and the detection signal of the second shift detection sensor 44 are simultaneously A / T.
When input to the ECU 40, the first shift device 22
The motor 10 is controlled on the basis of the detection signal based on the shift operation of No. 1 and the shift position of the A / T 6 is switched.

In step 150, only the first shift device 22 is activated, and the detection signal of the first shift detection sensor 42 based on the shift operation of the first shift device 22 is processed as valid.

In the following step 160, the second shift device 26 is deactivated, and the detection signal of the second shift detection sensor 44 based on the shift operation of the second shift device 26 is treated as invalid.

5 and 6 show an example of the shift control of the A / T6. As shown in FIG. 5, when the actual determination position is the D position, the setting signal of the manual cut switch 36 is set to the timing t1 to t4.
The first shift device 22 is activated and the second shift device 26 is deactivated when turned ON for the period up to. Therefore, even if the second shift device 26 is shifted to the -position at the timing t2, the detection signal is treated as invalid, and the determination position is maintained at the D position.

When the first shift device 22 is operated to shift to the R position at the timing t3, the detection signal is processed as valid, so that the determination position is R.
The position is changed.

When the setting signal of the manual cut switch 36 is turned off at the timing t4, both the first shift device 22 and the second shift device 26 are activated. At timing t5, when the driver's seat door 24 is opened and the detection signal of the door switch 46 is turned on, the first
The shift device 22 is activated and the second shift device 2
6 is made inactive. Therefore, the timing t6
In the case where the second shift device 26 is shifted to the D position, the detection signal is processed as invalid,
The judgment position is maintained at the R position.

FIG. 6 shows the manual cut switch 3
6 shows an example of the shift control of the A / T 6 when the setting signal of No. 6 and the detection signal of the door switch 46 are not input.

Since the setting signal of the manual cut switch 36 and the detection signal of the door switch 46 are not input,
Both the first shift device 22 and the second shift device 26 are activated. When the second shift device 26 is shifted to the R position at the timing t7 in the state where the actual determination position is the P position, the detection signal is processed as valid and the determination position is changed to the R position.

Next, when the first shift device 22 is shifted to the D position at the timing t8, the second shift device 26 outputs the R position detection signal, but the first shift device 22 detects it. Since the signal is preferentially processed, the determination position is changed to the D position. The detection signal of the second shift device 26 is output until the timing t9, but the detection signal of the first shift device 22 is output until the timing t10 after the timing t9, so the determination position is maintained at the D position. Thus, when both the first shift device 22 and the second shift device 26 are activated, the first shift device 2
When the second shift operation and the shift operation of the second shift device 26 are simultaneously performed, the shift operation by the first shift device 22 is preferentially processed.

According to this embodiment described above, the following effects can be obtained. (1) In the present embodiment, the shift operation for selecting a plurality of shift positions of the A / T 6 is performed by the first shift detection sensor 4
The first shift device 22 that electrically detects the second shift device 26 and the second shift device 26 that similarly electrically detects the shift operation for selecting a plurality of shift positions of the A / T 6 by the second shift detection sensor 44 are provided. . Then, the shift detection signal of the first shift detection sensor 42 is prioritized over the shift detection signal of the second shift detection sensor 44.
Therefore, the shift detection signal of the first shift detection sensor 42 based on the shift operation of the first shift device 22 and the second shift detection sensor 4 based on the shift operation of the second shift device 26.
When the shift detection signal of No. 4 and the shift detection signal of No. 4 are input at the same time, the motor 10 can be controlled based on the shift detection signal of the first shift detection sensor 42. Therefore, it is possible to avoid interference between the shift detection signal of the first shift device 22 and the shift detection signal of the second shift device 26.

(2) In this embodiment, when the collision of the vehicle is detected while the engine 2 is operating, the driving of the motor 10 based on the shift detection signal of the second shift detection sensor 44 is prohibited. That is, when an abnormal external force acts due to a vehicle collision, the second shift device 26 provided on the driver's door 24 may be damaged and the reliability of the shift detection signal of the second shift detection sensor 44 may be reduced. It is possible to prevent the operation of the motor 10 in the state.

(3) In the present embodiment, when the vehicle door (driver's seat door 24) is opened while the engine 2 is in operation, the driving of the motor 10 based on the shift detection signal of the second shift detection sensor 44 is prohibited. I have to. When the driver's seat door 24 is opened, the second shift device 26 also moves,
Although the operability of the shift lever 31 may decrease due to the second shift device 26 moving away from the driver or the arrangement angle changing, the operation of the motor 10 in this state can be prevented.

(4) In the present embodiment, since the second shift device 26 is arranged on the vehicle door (driver's door 24), it is possible to eliminate the interference between the steering operation and the shift operation by the second shift device 26. Yes, the second shift device 26
The shift operability due to can be improved.

(5) In this embodiment, the position arrangement of the first shift device 22 and the position arrangement of the second shift device 26 are the same with respect to the vehicle. Therefore, the shift operation of the first shift device 22 and the shift operation of the second shift device 26 are the same with respect to the vehicle. Therefore, the shift operation is performed using either the first shift device 22 or the second shift device 26. Are the same and the operability can be improved. Further, since the plurality of operation positions of the first shift device 22 and the second shift device 26 correspond to the plurality of shift positions of the A / T 6, a desired shift is performed by operating any one of the shift levers 31. The position can be easily and surely selected, and the shift operability can be improved.

(Second Embodiment) Next, a second embodiment of the present invention will be described with reference to FIG. In the first embodiment described above, the detection signal of the first shift detection sensor 42 is prioritized over the detection signal of the second shift detection sensor 44. In the present embodiment, the first shift device 22
When one of the second shift device 26 and the second shift device 26 fails, the A / TECU 40 invalidates the detection signal of the failed device and controls the motor 10 based on the detection signal of the device that is not invalidated. There is. Further, when both the first shift device 22 and the second shift device 26 fail, the A / TECU 40 invalidates the detection signals of both devices and controls the position of the A / T 6 based on whether the vehicle is stopped. It is supposed to do.

In this embodiment, the system configuration of a vehicle equipped with an automatic transmission and its shift control device is the same as that of the first embodiment. In this embodiment, the A / TECU
The shift control process executed by 40 will be described with reference to the flowchart of FIG. 7. This process is a process that is repeatedly executed periodically at preset short time intervals.

When this process is started, first, step 2
At 00, it is determined whether the first shift device 22 is failing, that is, whether the first shift detecting sensor 42 is failing. The detection signal of the first shift detection sensor 42 is output while the shift lever 31 is being operated to any operation position. The operation time of the shift lever 31 is short, and when the operation is released, the shift lever 31 returns to the operation center position. Therefore, when the detection signal of the first shift detection sensor 42 is output for a predetermined time or more, it can be determined that the first shift detection sensor 42 has failed. The predetermined time for determining the failure of the first shift detection sensor 42 is set to a value in which the operation time of the shift lever 31 has a margin time. First shift device 2
If it is determined that 2 is failing, the process is step 2
When it is determined that the first shift device 22 has not failed, the process proceeds to step 210.

In step 210, the second shift device 2
It is determined whether 6 is failing, that is, whether the second shift detection sensor 44 is failing. The failure of the second shift detection sensor 44 can also be determined based on that detection signal being output for a predetermined time or longer. If it is determined that the second shift device 26 has failed, the process proceeds to step 240
When it is determined that the shift device 26 has not failed, the routine proceeds to step 220.

In step 220, both the first shift device 22 and the second shift device 26 are activated. As a result, the first operation based on the shift operation of the first shift device 22 is performed.
The detection signal of the shift detection sensor 42 is processed as valid, and the detection signal of the second shift detection sensor 44 based on the shift operation of the second shift device 26 is processed as valid.

In the next step 230, the first shift device 2
The detection signal based on the second shift operation is the second shift device 26.
Is prioritized with respect to the detection signal based on the shift operation. That is, the detection signal of the first shift detection sensor 42 and the detection signal of the second shift detection sensor 44 are simultaneously A / T.
When input to the ECU 40, the detection signal based on the shift operation of the first shift device 22 is preferentially processed.

Further, in step 240, only the first shift device 22 is activated, and the detection signal of the first shift detection sensor 42 based on the shift operation of the first shift device 22 is processed as valid.

In the following step 250, the second shift device 26 is deactivated, and the detection signal of the second shift detection sensor 44 based on the shift operation of the second shift device 26 is treated as invalid.

In step 260 after the step 200, it is determined whether the second shift device 26 is failing, that is, the second shift detecting sensor 44 is failing. If it is determined that the second shift device 26 has failed, the process proceeds to step 290, and if it is determined that the second shift device 26 has not failed, the process proceeds to step 270.

In step 270, only the second shift device 26 is activated, and the detection signal of the second shift detection sensor 44 based on the shift operation of the second shift device 26 is processed as valid.

In the following step 280, the first shift device 22 is deactivated, and the detection signal of the first shift detection sensor 42 based on the shift operation of the first shift device 22 is treated as invalid.

In step 290, which is a transition from step 260, it is determined whether or not the vehicle is stopped. If it is determined that the vehicle is stopped, the process proceeds to step 320, and if it is determined that the vehicle is not stopped, the process proceeds to step 300.

In step 300, the first shift device 22
Since both the second shift device 26 and the second shift device 26 are determined to have failed and the vehicle is not stopped, the current shift position is maintained without switching the shift position of the A / T 6 by driving the motor 10. .

Then, in the next step 310, the first
Both the shift device 22 and the second shift device 26 are deactivated. That is, the detection signal of the first shift detection sensor 42 based on the shift operation of the first shift device 22 and the detection signal of the second shift detection sensor 44 based on the shift operation of the second shift device 26 are processed as invalid.

In step 320, it is determined that both the first shift device 22 and the second shift device 26 have failed, and since the vehicle is stopped, the motor 10 is driven to drive the A / T 6 The shift position is switched to the P position.

Then, in the next step 330, the first
Both the shift device 22 and the second shift device 26 are deactivated. That is, the detection signal of the first shift detection sensor 42 based on the shift operation of the first shift device 22 and the detection signal of the second shift detection sensor 44 based on the shift operation of the second shift device 26 are processed as invalid.

According to the present embodiment described above, in addition to the effects (1), (4) and (5) of the first embodiment,
The following effects can be obtained. (6) In the present embodiment, the first shift device 22 and the second shift device 22

Interference between the detection signal based on the operation and the detection signal based on the shift operation of the second shift device 26 can be avoided.

(7) Further, when both the first shift device 22 and the second shift device 26 fail, the shift detection signals of both shift devices are invalidated, and when the vehicle is not stopped, the shift position of the A / T 6 is set. Switching can be prevented, and the A / T 6 can be switched to the P position when the vehicle is stopped.

(Third Embodiment) Next, a third embodiment of the present invention will be described with reference to FIGS. In the first embodiment described above, the detection signal of the first shift detection sensor 42 is prioritized over the detection signal of the second shift detection sensor 44. On the other hand, in this embodiment, the priority is set to the detection signals of the shift devices 22 and 26, and the detection signals of the shift devices 22 and 26 are set to A at the same time.
When input to the / TECU 40, the motor 10 is controlled based on the detection signal having the higher priority. In the present embodiment, the priority of the detection signal is the P shift detection signal, the N shift detection signal, the R shift detection signal or the D shift detection signal, the + shift detection signal, or the −.
The order of shift detection signals is in this order.

In this embodiment, the system configuration of a vehicle equipped with an automatic transmission and its shift control device is the same as that of the first embodiment. Next, the shift control process executed by the A / TECU 40 will be described with reference to the flowchart of FIG. This process is a process that is repeatedly executed periodically at preset short time intervals.

When this process is started, first, step 4
At 00, it is determined whether the driver's seat door 24 is open based on the detection signal of the door switch 46. If it is determined that the driver's door 24 is open, the process proceeds to step 450, and if it is determined that the driver's door 24 is not open, the process proceeds to step 410.

At step 410, it is judged based on the detection signal of the collision detection sensor 48 whether the vehicle has collided. If it is determined that the vehicle has collided, the process proceeds to step 45.
When it is determined that the vehicle has not collided, the routine proceeds to step 420.

In step 420, it is determined whether the second shift device 26 is invalidated based on whether the setting signal of the manual cut switch 36 is ON. If it is determined that the setting signal of the manual cut switch 36 is ON, the process proceeds to step 350, and if it is determined that the setting signal of the manual cut switch 36 is OFF, the process proceeds to step 430.

In step 430, both the first shift device 22 and the second shift device 26 are activated. As a result, the first operation based on the shift operation of the first shift device 22 is performed.
The detection signal of the shift detection sensor 42 is processed as valid, and the detection signal of the second shift detection sensor 44 based on the shift operation of the second shift device 26 is processed as valid.

In the next step 440, the first shift device 2

When it is input to 40, the processing based on the preset priority of the detection signal is executed, and this routine is ended.

Further, in step 450, only the first shift device 22 is activated, and the detection signal of the first shift detection sensor 42 based on the shift operation of the first shift device 22 is processed as valid.

In the following step 460, the second shift device 26 is deactivated, and the detection signal of the second shift detection sensor 44 based on the shift operation of the second shift device 26 is treated as invalid.

9 to 12 show an example of the shift control of the A / T6. These examples show an example of shift control in a state where the setting signal of the manual cut switch 36 and the detection signal of the door switch 46 are not input. Since the setting signal of the manual cut switch 36 and the detection signal of the door switch 46 are not input, both the first shift device 22 and the second shift device 26 are activated.

In the example shown in FIG. 9, when the second shift device 26 is shifted to the N position at the timing t11 in the state where the actual determination position is the P position, the actual determination position is based on the N shift detection signal. The position is changed to the N position. The N shift detection signal of the second shift device 26 is output from timing t11 to timing t13.

Next, at timing t12, the first shift device 22 is shifted to the R position and the R shift detection signal is output. At this time, the N shift detection signal of the second shift device 26 is output. Since the N shift detection signal has a higher priority than the R shift detection signal, the shift position switching based on the R shift detection signal of the first shift device 22 is not performed, and the actual determination position is maintained at the N position.

In the example shown in FIG. 10, when the second shift device 26 is shifted to the-position at the timing t14 in the state where the actual determination position is the D position, the actual determination is made based on the-shift detection signal. The position is changed to 3 positions which is one step lower than the D position. The-shift detection signal of the second shift device 26 is output from timing t14 to timing t16.

Next, at timing t15, the first shift device 22 is shifted to the R position and the R shift detection signal is output. At this time, the second shift device 26
However, since the R shift detection signal has a higher priority than the -shift detection signal, the actual determination position is changed to the R position based on the R shift detection signal.

Further, in the example shown in FIG. 11, when the actual determination position is the P position, the timing t
When the second shift device 26 is operated to shift to the D position in 17, the actual determination position is changed to the D position based on the D shift detection signal. The D shift detection signal of the second shift device 26 is output from timing t17 to timing t19.

Next, at timing t18, the first shift device 22 is shifted to the P position and the P shift detection signal is output. At this time, the second shift device 26
However, since the P shift detection signal has a higher priority than the D shift detection signal, the actual determination position is P based on the P shift detection signal of the first shift device 22. The position is changed.

Further, in the example shown in FIG. 12, when the second shift device 26 is shifted to the N position at the timing t20 in the state where the actual determination position is the P position, the actual shift is made based on the N shift detection signal. The judgment position of is changed to the N position. Second
The N shift detection signal of the shift device 26 is at the timing t20.
After that, it is output until timing t22.

Next, at timing t21, the first shift device 22 is shifted to the P position and the P shift detection signal is output. At this time, the second shift device 26
However, since the P shift detection signal has a higher priority than the N shift detection signal, the actual determination position is P based on the P shift detection signal of the first shift device 22. The position is changed.

According to this embodiment described above, the following effects can be obtained in addition to the effects (4) and (5) of the first embodiment. (8) In the present embodiment, the shift operation of selecting a plurality of shift positions of the A / T 6 is performed by the first shift detection sensor 4
The first shift device 22 that electrically detects the second shift device 26 and the second shift device 26 that similarly electrically detects the shift operation for selecting a plurality of shift positions of the A / T 6 by the second shift detection sensor 44 are provided. . Then, in the shift operation by the first shift device 22 and the second shift device 26, “P>N> R” regarding P shift operation, N shift operation, R shift operation or D shift operation, and −shift operation or + shift operation. Or, the priority order was set in the order of D> + or − ”. Therefore, when the detection signal of the first shift detection sensor 42 based on the shift operation of the first shift device 22 and the detection signal of the second shift detection sensor 44 based on the shift operation of the second shift device 26 are simultaneously input, The motor 10 can be controlled based on the priority of the detection signals, and the interference between the detection signal based on the shift operation of the first shift device 22 and the detection signal based on the shift operation of the second shift device 26 can be avoided. .

(Fourth Embodiment) Next, a fourth embodiment of the present invention will be described with reference to FIGS. In the third embodiment, the priority order is set for the types of the detection signals of the first shift device 22 and the second shift device 26, and the motor 10 is controlled based on the detection signal of the high priority order to control the A / A ratio. The shift position of T6 is switched. On the other hand, in the present embodiment, each shift device 22,

If it is determined that the value is "NO", the process proceeds to step 520.

At step 520, it is judged whether or not the cancellation processing of the incoming signal is being executed, by judging whether or not it is within the prohibition time Ts from the last signal reception. If it is determined that the incoming signal is being canceled, this routine is once ended. If it is determined that the incoming signal is not being canceled, the process proceeds to step 530.

In the prohibition time setting map 50, the prohibition time T
s is determined based on the combination of the shift operations of the first shift device 22 and the second shift device 26, that is, the type of the detection signal received first and the type of the detection signal received next. For example, when the N shift detection signal arrives after the P shift detection signal is received, the inhibition time Ts is T
The prohibition time Ts when the P shift detection signal arrives after the N shift detection signal is received is TsNP.
Has become. These prohibited times TsPN and TsNP
Can be set to any value, and the prohibited time T
It is also possible to set sPN and TsNP to equal values.

Then, in step 590, from the time when the detection signal of the first shift detection sensor 42 is received, the above step 5

In step 540 following step 510, the motor 10 is controlled based on the detection signal of the second shift detection sensor 44 based on the shift operation of the second shift device 26, and the A / T6 shift position is switched.
Proceed to step 550.

In step 550, the signal reception inhibition time Ts for each shift operation is set with reference to the inhibition time setting map 50 shown in FIG. And step 560

Then, the reception of the D shift detection signal of the first shift device 22 is canceled, the shift position switching based on the D shift detection signal of the first shift device 22 is not performed, and the actual determination position is maintained at the R position.

In the example shown in FIG. 15, when the second shift device 26 is shifted to the D position at timing t26 in the state where the actual determination position is the P position, the actual determination is made based on the D shift detection signal. The position is changed to the D position. Timing t

The measurement of the elapsed time T is started. The R shift detection signal of the second shift device 26 is output from timing t30 to timing t32.

Next, the first shift device 22 is shifted to the D position and the D shift detection signal is output at the timing t31 within the period of the determination time Td from the time when the R shift detection signal of the second shift device 26 is received.

In the example shown in FIG. 22, when the second shift device 26 is shifted to the D position at the timing t38 in the state where the actual determination position is the P position, the timer is generated based on the rising edge of the D shift detection signal. The measurement of the elapsed time T is started. The D shift detection signal of the second shift device 26 is output from timing t38 to timing t41.

The detection signal of the first shift device 22 has not arrived within the period from the timing t38 to the elapse of the determination time Td. Therefore, at the timing t39 when the determination time Td has elapsed, the actual determination position is changed to the D position based on the D shift detection signal of the second shift device 26.

At timing t40 after timing t39, the R shift detection signal is received from the first shift device 22. At this time, the second shift device 26
