Description

  The present invention relates to a notification device for a vehicle with an automatic transmission, and in particular, when an automatic transmission is in a manual shift mode, a cumulative calculation value of a physical quantity indicating an operating state of an engine with a shift speed fixed exceeds a predetermined threshold. In some cases, the present invention relates to a notification device that determines that switching of a gear position by a manual operation by the driver is inappropriate and notifies the driver of the switching operation regarding the shift mode or the gear position.

  Conventionally, in an automatic transmission mounted on a vehicle (automobile), the shift mode can be switched automatically between an automatic shift mode in which the shift stage is automatically switched based on a predetermined shift characteristic, and the driver can manually switch the shift stage. It is well known that it can be switched to a manual shift mode, and this shift mode is generally switched to the automatic shift mode when the driver manually operates the shift lever to switch to the drive range. When switched to the manual range, the manual shift mode is switched (for example, see Patent Document 1).

  In this type of automatic transmission, the gear position is normally switched by the driver manually operating the shift lever located in the manual range in the front-rear direction while being switched to the manual shift mode. Here, in an automatic transmission that can be switched to a manual shift mode, a shift lever that is configured to switch from a non-traveling range to a manual range via a drive range has been put into practical use (for example, a patent) Reference 1).

  In the automatic transmission that can be switched to the manual shift mode, a manual shift mode switching switch is provided on the steering wheel, and the shift range is switched to the manual shift mode by turning on this switch by the driver. It is well known that the shift stage can be switched by providing a shift up / down switch on the steering wheel and the driver turning on the switch while the shift mode is switched to the manual shift mode.

  In the vehicle with the automatic transmission, when the driver is unfamiliar with the operation including the gear shifting operation to be performed with respect to the manual transmission mode of the automatic transmission, the manual transmission is not performed due to the erroneous operation of the transmission mode of the automatic transmission. When the mode is switched, or when the shift mode of the automatic transmission is switched to the manual shift mode, the user may forget that. For a driver who is unfamiliar with the operation for the manual transmission mode of the automatic transmission, there is a high possibility that the transmission mode of the automatic transmission is switched to the manual transmission mode by an erroneous operation.

  Here, in the vehicle with the automatic transmission, generally, the shift range in which the shift lever is switched is displayed on the shift range display (for example, any one of “P”, “R”, “N”, “D”, and “M”). The indicator lamp is lit (“M” is lit in the case of the manual shift mode). However, only by this, the driver may not notice that the mode has been switched to the manual shift mode.

  In such a case, the driver steps on the accelerator pedal in order to accelerate the vehicle. At this time, the gear position is held at a low speed (usually first gear), the engine speed is unnecessarily increased, and the gear position is Since there is a risk that the vehicle will run for a long time at the low speed stage, and fuel cut to the engine may be performed, the load on the engine and the engine exhaust system will increase, and the exhaust gas will also increase. Not good.

  Here, in particular, even if a driver who is not familiar with the manual transmission mode of the automatic transmission notices the display on the shift range display ("M" lights up), the meaning of the display is There is a possibility that it cannot be understood, and even if the meaning of the display can be understood, an appropriate operation to be performed next cannot be performed.

  In addition, in the case where the shift lever of the automatic transmission is configured to switch from the non-driving range to the manual range via the drive range, the driver intends to switch the shift lever from the non-driving range to the drive range, It is considered that an erroneous operation easily causes the drive range to be switched to the manual range, that is, to be switched to the manual shift mode, so that the above problem is likely to occur.

  It is an object of the present invention to perform a manual shift operation by a driver when a cumulative calculation value of a physical quantity indicating an operating state of an engine exceeds a predetermined threshold while a shift speed is fixed when the automatic transmission is in a manual shift mode.

And determining means for determining whether or not the speed change by the operation is inappropriate. When the determination means makes an affirmative determination, the driver performs the change operation for the shift mode or the speed. Is intended to notify the inner to the notification means, the determination means, the gear position in the absence of detection by the switching operation detecting means, before Symbol by accumulating engine speed sensed set higher rotational speed detecting means A cumulative calculation value is determined, and an affirmative determination is made when the cumulative calculation value exceeds a predetermined threshold value that is undesirable for engine operation.
According to a second aspect of the present invention, there is provided a notification device for a vehicle with an automatic transmission, wherein the shift mode of the automatic transmission is automatically switched based on a predetermined shift characteristic, and the driver manually operates the shift stage. In a vehicle with an automatic transmission provided with a shift mode switching means that can be switched to a manual shift mode that can be switched in, a notification means that can notify a driver, a notification control means that controls the notification means, and a driver And a detection means for detecting the exhaust temperature of the engine of the vehicle, wherein the notification control means is provided when the automatic transmission is in the manual shift mode. It has a judging means for judging whether or not the gear shift by manual operation is inappropriate, and when this judgment means makes a positive judgment, the gear change mode or the gear is switched to the driver. In the state where there is no detection by the shift stage switching operation detection means, the determination means is a duration in which the exhaust temperature of the engine detected by the detection means is equal to or higher than a set temperature. When the measured duration exceeds a predetermined threshold that is not desirable for engine operation, an affirmative determination is made.
According to a third aspect of the present invention, there is provided a notification device for a vehicle with an automatic transmission, wherein the shift mode of the automatic transmission is automatically switched based on a predetermined shift characteristic, and the driver manually operates the shift stage. In a vehicle with an automatic transmission provided with a shift mode switching means that can be switched to a manual shift mode that can be switched in, a notification means that can notify a driver, a notification control means that controls the notification means, and a driver And a detection means for detecting the coolant temperature of the engine of the vehicle, wherein the notification control means is provided when the automatic transmission is in the manual transmission mode.

The notification means is configured to notify the operation means, and the determination means is configured such that the engine coolant temperature detected by the detection means is not less than a set temperature in a state where the detection by the shift stage switching operation detection means is not performed. A duration is measured, and when the measured duration exceeds a predetermined threshold that is undesirable for engine operation, an affirmative determination is made.
According to a fourth aspect of the present invention, there is provided a notification device for a vehicle with an automatic transmission, wherein the shift mode of the automatic transmission is automatically switched based on a predetermined shift characteristic, and the driver manually operates the shift stage. In a vehicle with an automatic transmission provided with a shift mode switching means that can be switched to a manual shift mode that can be switched in, a notification means that can notify a driver, a notification control means that controls the notification means, and a driver And a detection means for detecting the number of fuel cuts of the vehicle engine, wherein the notification control means is provided when the automatic transmission is in the manual transmission mode. Determining means for determining whether switching of the gear position by manual operation is inappropriate, and when the determination means makes an affirmative determination, the shift mode or the gear position is switched to the driver. The notification means informs the operation guide of the operation, and the determination means determines that the number of engine fuel cuts detected by the detection means in the absence of detection by the shift speed change operation detection means An affirmative determination is made when an undesired predetermined threshold value is exceeded.

  In this vehicle notification apparatus with an automatic transmission, it is determined by the determination means of the notification control means whether or not the gear shift by manual operation by the driver is inappropriate when the automatic transmission is in the manual shift mode. When an affirmative determination is made, the notification means is controlled by the notification control means, and the notification means notifies the driver of the switching operation regarding the shift mode or the shift speed.

  If the driver is unfamiliar with the operation including the gear change operation for the manual transmission mode of the automatic transmission, or if the automatic transmission shift mode is switched to the manual transmission mode by mistake, If the shift mode is switched to the manual shift mode but you forget to do so, it may happen that the shift operation by the driver's manual operation becomes inappropriate when the automatic transmission is in the manual shift mode. In this case, the driver can surely perform an appropriate operation by notifying the guidance of the switching operation.

According to the notification device for a vehicle with an automatic transmission according to any one of claims 1 to 4 , the notification control means controls the notification means that can notify the driver, and the determination means of the notification control means determines that the automatic transmission is manually operated. In the mode, it is determined whether or not the shift operation by the driver's manual operation is inappropriate, and if the determination is affirmative, the notification means informs the driver of the switching operation for the shift mode or the shift step. Let me know.

  Therefore, if the driver is unfamiliar with the operation including the gear shift operation to be performed for the manual transmission mode of the automatic transmission, or if the shift mode of the automatic transmission is switched to the manual transmission mode by mistake, When the automatic transmission is in the manual shift mode, the gear shift by manual operation by the driver may become inappropriate. However, in this case, the driver can reliably perform an appropriate operation by notifying the guidance of the switching operation.

  In other words, the driver performs an operation to switch the shift mode from the manual shift mode to the automatic shift mode without delay, or an operation to switch the shift stage in the automatic shift mode, thereby suppressing an unnecessary increase in engine speed. Since it is possible to prevent the vehicle from traveling for a long time at a low gear, and because it is possible to suppress the fuel cut to the engine, it is possible to prevent an increase in the load on the engine and the engine exhaust system. .

Then, the operation of switching the gear stage by the driver is detected by the gear position switching operation detecting means, the engine speed, the exhaust gas temperature, the coolant temperature, and the number of fuel cuts are detected by the detecting means. in the absence of detection by the shift speed change operation detecting means, setting the rotational speed or the cumulative calculated value of the engine speed by accumulating time continuously exhaust temperature is the set temperature or higher, the duration coolant temperature is the set temperature or more Alternatively, the determination is affirmative when the number of fuel cuts exceeds a predetermined threshold that is not desirable for engine operation.

  That is, whether or not the shift control by manual operation by the driver is inappropriate when the automatic transmission is in the manual shift mode, corresponding to whether or not the determination unit of the notification control unit is preferable for engine operation. Therefore, in cases other than the case where the engine operation is not preferable, a negative determination is made even when the engine load becomes large to some extent, so that the guidance for the switching operation is not notified. Since the notification of guidance can be carried out to the minimum necessary, a balanced notification is made so as not to bother the driver (especially the driver who is aware that the manual shift mode has been switched). be able to.

Further , whether or not the shift control by manual operation by the driver is inappropriate when the automatic transmission is in the manual shift mode according to whether or not the determination unit of the notification control unit is preferable for engine operation. Can be judged reliably.

The present invention is applied to a vehicle with an automatic transmission provided with a shift mode switching means capable of switching to a switchable manual shift mode.

As shown in FIG. 1, a shift lever 1 for selecting a shift range of an automatic transmission mounted on a vehicle (automobile) is a cover attached to a center console 2 between a driver seat and a passenger seat of the vehicle. 3 is provided so as to protrude upward. A zigzag-shaped shift gate 4 is formed on the cover 3, and the shift lever 1 is inserted through the shift gate 4. By shifting the shift lever 1 along the shift gate 4, the shift range can be alternatively selected from the P range, R range, N range, D range, and M range.

  P range and N range correspond to non-running ranges, and D range (drive range) is a range for selecting an automatic shift mode in which the shift stage of the automatic transmission is automatically switched based on a predetermined shift characteristic, The M range (manual range) is a range in which the driver selects a manual shift mode in which the shift stage of the automatic transmission can be switched manually.

  FIG. 2 shows positions of the shift lever 1 in the shift gate 4 corresponding to the P, R, N, D, and M ranges, respectively. As shown in FIG. 2, the shift lever 1 is operated from the P range in the direction of the arrow, so that the R range (left → down → right from the P range), the N range (down → right from the R range), the D range (From N range down) and M range (from D range to right) are reversibly switched in sequence, and in M range, shift lever 1 is operated backward from the neutral position of M range and the gear position is switched to the up side. When operated forward, the gear position is switched to the down side. Thus, the shift lever 1 is configured to switch from the non-traveling range (P, N range) to the M range via the D range.

  As shown in FIG. 1, the cover 3 includes “P”, “R”, “N”, and “D” indicating positions of the shift lever 1 corresponding to the P, R, N, D, and M ranges in the shift gate 4 respectively. “M” indicator portions are provided, and “+” and “−” indicator portions indicating the shift-up operation direction and the shift-down operation direction of the shift lever 10 in the M range are provided.

  As shown in FIG. 3, a display device 11 is provided on the instrument panel 10 in front of the driver's seat of the vehicle. In addition to the tachometer 12, the speedometer 13, the water temperature gauge 14, the fuel gauge 15, and the like, the display device 11 is provided with a shift range display unit 16, a shift stage display unit 17, and a multi display unit 18.

  As shown in FIGS. 3 and 4, the shift range display unit 16 displays the selected shift range of the automatic transmission. For example, “P” “R” “N” “ The indicator lamps 16a to 16e are formed of light emitting diodes D and "M", and the indicator lamp (any one of 16a to 16e) corresponding to the selected shift range is turned on. The gear stage display unit 17 displays a selected gear stage of the automatic transmission when the gear range of the automatic transmission is selected as the M range, and includes, for example, a 7-segment light emitting diode display.

  The multi display unit 18 includes, for example, a liquid crystal display that displays various information, and the multi display unit 18 corresponds to a notification unit that can notify the driver. Next, the notification device 5 (hereinafter referred to as the notification device 5) for a vehicle with an automatic transmission according to the present invention will be described in detail.

  As shown in FIG. 5, the notification device 5 includes a shift range display unit 16, a shift stage display unit 17, a multi display unit 18, a control unit 20, P, R, N, D, M range switches 21 to 25, and a shift up. , Down switches 26 and 27. The P, R, N, D, and M range switches 21 to 25 can detect the shift range in which the shift lever 1 stays, and the shift up and down switches 26 and 27 are used to perform the shift up operation of the shift lever 1. Each of the downshift operations can be detected. The upshift and downswitches 26 and 27 correspond to shift speed change operation detecting means for detecting an operation of the driver to change the shift speed.

  Further, the control unit 20 is electrically connected to the engine control system 28 and the automatic transmission control system 29 and has a necessary configuration in the control systems 28 and 29. Based on the detection signals received from the switches 21 to 27, and further based on the signals received from the engine control system 28 and the automatic transmission control system 29, the control unit 20 further includes a shift range display unit 16, a shift stage display unit 17, The multi display unit 18 is controlled. The control unit 20 corresponds to notification control means for controlling the notification means (multi-display unit 18).

  Here, the P, R, N, D, M range switches 21 to 25 and the automatic transmission control system 29 serve as a transmission mode switching means capable of switching the transmission mode of the automatic transmission between the automatic transmission mode and the manual transmission mode. Equivalent to. The control unit 20 may be configured in common with the control units of the engine control system 28 and the automatic transmission control system 29.

  In this notification device 5, in particular, when the control unit 20 determines whether or not switching of the gear position by the manual operation of the driver is inappropriate when the automatic transmission is in the manual shift mode, and makes an affirmative determination, It is configured to notify the driver of the switching operation regarding the shift mode or the shift speed. Next, the notification control executed by the control unit 20 will be described in detail with reference to FIGS. A program for executing the notification control is stored in the computer ROM of the control unit 20.

  As shown in FIG. 6, when the notification control is started, after the initial setting, it is first determined whether or not the automatic transmission is in the manual transmission mode based on the transmission mode information received from the automatic transmission control system 29 ( In the case of S1) and S1; No, the process returns to the S1 standby state, and in the case of S1; Yes, manual shift operation inappropriate determination processing (S2, corresponding to determination means) is executed.

  The inadequate manual shift operation determination process in S2 is a process for determining whether or not the gear shift by manual operation by the driver is inappropriate when the automatic transmission is in the manual shift mode. In the appropriate determination process, as shown in FIG. 7, first, the engine exhaust (cooling water) temperature T detected by the engine control system 28 (detecting means) is read (S10), and then the temperature read in S10. It is determined whether T is equal to or higher than a set temperature CT (for example, 100 degrees) (S11).

  In the case of S11; Yes, the high temperature duration Tt is measured (S12), and then it is determined whether or not the high temperature duration Tt measured in S12 is equal to or longer than the set high temperature duration TtA (for example, 180 seconds) (S13). ). In the case of S11; No or S13; No, it is determined whether or not the shift lever 1 has been switched to the D range, that is, whether or not the D range switch 24 is on (S14). S14: In the case of No, it is determined whether or not the driver has manually operated the gear position, that is, whether or not the upshift switch 26 or the downshift switch 27 is on (S15).

  If S14: Yes or S15; Yes, the high temperature duration Tt is reset to 0 (S16), the operation returns without being judged as inappropriate, S15: If No, the process returns to S10, S13: Yes If the operation is determined to be inappropriate (S17), the process returns. As shown in FIG. 8, when the engine exhaust (cooling water) temperature T changes as shown, S10 to S15 are repeatedly executed from time t1 to current time t2, and the high temperature duration time Tt is set at time t2. When the high temperature duration time TtA is reached, S13; Yes is determined, and it is determined that the operation is inappropriate (S17).

  In this manual shift operation inadequate determination process, one physical quantity (engine exhaust (cooling)) relating to the detected engine operating state is detected in a state where the driver has not detected an operation to switch the shift stage (S14; No, S15; No). Water) When the operation value for determination (high temperature duration Tt) determined based on the temperature T) exceeds a predetermined threshold (set high temperature duration TtA) that is not preferable for engine operation, the operation is inappropriate. Make an affirmative decision.

  As shown in FIG. 6, after the manual shift operation inappropriateness determination process of S2, if the operation is not inappropriate (S3; No), the process returns to S1, and if the operation is inappropriate (S3; Yes), the shift mode or The driver is informed of the switching operation for the shift speed (S4). As for the notification of the operation guidance, as shown in FIG. 9, a shift gate schematic diagram 30 and a shift lever schematic diagram 31 staying in the M range are displayed in perspective on the multi-display unit 18, and the shift mode switching operation guidance is displayed. As shown, an arrow 32 indicating the direction of operation for switching to the D range is displayed.

  Alternatively, as shown in FIG. 10, the multi-display unit 18 includes a shift gate schematic diagram 30, a shift lever schematic diagram 31, and an arrow 33 indicating a shift operation direction to the shift-up side as a gear shift operation guide. Is displayed. Alternatively, as shown in FIG. 11, the multi-display unit 18 includes a shift gate schematic diagram 30, a shift lever schematic diagram 31, an arrow 32 as a shift mode switching operation guide, and an arrow as a shift speed switching operation guide. 33 is displayed.

  As other display forms corresponding to FIGS. 9 to 11, for example, “Please operate the shift lever to the D range”, “Please raise the shift stage with the shift lever”, “Operate the shift lever to the D range” Alternatively, use the shift lever to raise the gear position "or the like. FIGS. 9 to 11 are notifications that promote the switching of the shift mode or the shift speed, but in order to perform further emphasized notifications, the following may be performed.

  As a notifying means, a sound generating device (not shown) for notifying by voice is added, and both the multi-display unit 8 and the sound generating device are notified of the switching operation. In this case, the screen of any of FIGS. 9 to 11 is displayed on the multi-display unit 18, and the voice generator corresponding to the screen “operates the shift lever to the D range”, “shifts with the shift lever” Either “Please raise the gear” or “Operate the shift lever to the D range or raise the gear with the shift lever” may be output as a voice. In addition, it is good also as alert | reporting only by an audio | voice generator.

  As shown in FIG. 6, after S4, when the D range switch 24 is turned on (S5; Yes), or when the upshift and down switches 26, 27 are turned on (S6; Yes), S4 (S7), the process returns to S5; No, S6; If No, the process returns to S5 and the switching operation guidance is continued.

The notification device 1 described above has the following effects.
The control unit 20 controls the multi-display unit 18 that can notify the driver, and determines whether or not the gear shift by manual operation by the driver is inappropriate when the automatic transmission is in the manual shift mode. When an affirmative determination is made, the multi-display unit 18 is notified of a switching operation guide for the driver regarding the shift mode or the shift speed.

  Therefore, if the driver is unfamiliar with the operation including the gear shift operation to be performed for the manual transmission mode of the automatic transmission, or if the shift mode of the automatic transmission is switched to the manual transmission mode by mistake, When the automatic transmission is in the manual shift mode, the gear shift by manual operation by the driver may become inappropriate. However, in this case, the driver can reliably perform an appropriate operation by notifying the guidance of the switching operation.

  In other words, the driver performs an operation to switch the shift mode from the manual shift mode to the automatic shift mode without delay, or an operation to switch the shift stage in the automatic shift mode, thereby suppressing an unnecessary increase in engine speed. Since it is possible to prevent the vehicle from traveling for a long time at a low gear, and because it is possible to suppress the fuel cut to the engine, it is possible to prevent an increase in the load on the engine and the engine exhaust system. .

  The control unit 20 performs a determination calculation value (high temperature duration Tt) determined based on the detected physical quantity (engine exhaust (cooling water) temperature T) without detection by the upshift and downswitches 26 and 27. However, when it exceeds a predetermined threshold value (set high temperature duration time TtA) that is not preferable for engine operation, it is determined that the operation is inappropriate.

  That is, it is possible to reliably determine whether or not the gear shift by manual operation by the driver is inappropriate when the automatic transmission is in the manual shift mode, depending on whether or not the engine operation is preferable. In cases other than when the operation is not preferable, a negative determination is made even when the engine load increases to some extent, so that the switching operation guidance is not notified, and the switching operation guidance notification is minimized. Since the operation can be carried out in a reduced manner, it is possible to provide a balanced notification without causing trouble to the driver (in particular, a driver who is aware that the manual transmission mode has been switched).

  Since the control unit 20 is informed so as to promote the change of the shift mode or the shift speed, it is possible to make the notification more excellent so that the driver can surely perform an appropriate operation. If the guidance for the switching operation is performed by one of the multi-display unit 18 and the sound generator, the configuration for notification can be simplified, and if it is performed by both the multi-display unit 18 and the sound generator, The notification can be more reliably recognized by the driver.

The second embodiment is a modification of the manual shift operation inappropriateness determination process of the first embodiment . In this manual shift operation inappropriate determination process, as shown in FIG. 12, first, the engine speed R detected by the engine control system 28 is read (S20), and then the engine speed R read in S20. Is greater than or equal to the set rotational speed CR (for example, 6000 rpm) (S21).

  In the case of S21; Yes, the high engine speed integral value IR is rewritten to IR + (R-CR) based on the engine speed R read in S20 (S22), and then the high engine speed rewritten in S22. It is determined whether or not the integral value IR is greater than or equal to the set high rotational speed integral value IRA (S23). If S21; No or S23; No, it is determined whether or not the D range switch 24 is on (S24). If S24; No, it is determined whether or not the upshift and down switches 26 and 27 are on (S25). .

  If S24: Yes or S25; Yes, the high-speed integral value IR is reset to 0 (S26), the operation returns without being determined as inappropriate, and if S25; No, the operation returns to S20, S23: Yes In this case, it is determined that the operation is inappropriate (S27), and the process returns. As shown in FIG. 13, when the engine speed R changes as shown in the figure, S20 to S25 are repeatedly executed from time t1 to time t2, and from time t3 to current time t4, and high at time t4. When the rotational speed integral value IR (which corresponds to the cumulative calculation value of the physical quantity) reaches the set high rotational speed integral value IRA, S23 is Yes and it is determined that the operation is inappropriate (S27).

  In the manual shift operation inappropriate determination process, one physical quantity (engine speed R) relating to the detected engine operating state in a state where the driver does not detect an operation to switch the shift speed (S24; No, S25; No). ) Is determined to be inappropriate when the calculation value for determination (high-speed integral value IR) exceeds a predetermined threshold value (set high-speed integral value IRA) that is undesirable for engine operation. Make an affirmative decision.

The third embodiment is a modification of the manual shift operation inappropriateness determination process of the first embodiment . In this manual shift operation inappropriate determination process, as shown in FIG. 14, it is first determined whether or not engine fuel cut has been performed by the engine control system 28 (S30). If S30; Yes, the fuel cut frequency Cf is It is incremented to Cf + 1 (S31), and then it is determined whether or not the fuel cut number Cf is equal to or greater than the set fuel cut number CfA (for example, three times) (S32).

  In the case of S30; No or S32; No, it is determined whether or not the D range switch 24 is on (S33). In the case of S33; No, it is determined whether or not the upshift and down switches 26 and 27 are on (S34). . S33: Yes or S34; If Yes, the fuel cut count Cf is reset to 0 (S35), return without being determined as inappropriate operation, S34; If No, return to S30, S32: Yes Then, it is determined that the operation is inappropriate (S36), and the process returns.

  In this manual shift operation inappropriate determination process, one physical quantity (engine fuel cut-off state) relating to the detected engine operating state is detected in a state where the driver has not detected an operation to switch the shift stage (S33; No, S34; No). The determination calculation value (engine fuel cut frequency Cf) (which corresponds to the cumulative calculation value of the physical quantity) determined based on the presence / absence) exceeds a predetermined threshold value (set fuel cut frequency CfA) that is undesirable for engine operation. Affirmative judgment that the operation is inappropriate.

Of manual shift operation improper determination processing of the actual Example 1 to 3 of 3 patterns, run in parallel at least two manual shift operation improper determination process, at least one of these manual shift operation improper determination processing operation If it is determined to be inappropriate, the notification of the operation guidance in S4 is executed, or the notification of the operation guide in S4 is performed only when all of the manual shift operation inappropriateness determination processes are determined to be inappropriate. To be executed.
[Reference Example 1]

In Reference Example 1, the control unit 20 determines whether the shift lever 1 has been switched from the P (or N) range so as to go straight to the M via the D range. the judged by equivalent) to the determination unit, as set hot duration TtA used in manual shift operation improper determination process in example 1, when a negative decision is made in M range erroneous operation determination processing, a predetermined first setting high temperature duration When Tt1 is adopted and an affirmative determination is made in the M range erroneous operation determination process, a second set high temperature duration Tt2 lower than the first set high temperature duration Tt1 is adopted.

  In this M range erroneous operation determination process, as shown in FIG. 15, first, whether or not the shift lever 1 stays in the P (or N) range, that is, the P range switch 21 (or N range switch 23) is turned on. (S40), and if S40; Yes, the process returns to the S40 standby state.

  S40: If No, it is determined whether or not the shift lever 1 is switched to the D range, that is, whether the D range switch 24 is on (S41). If S41; Yes, the D range stay flag DF is set to 1. It is set (S42) and the D-range stay time t is counted (S43). If S41; No, it is determined whether or not DF = 1 (S44). If S44; No, the process returns. If S44; Yes, t measured in S43 is stored as Dt, and DF and t are 0. (S45).

  Next, it is determined whether or not the shift lever 1 has been switched to the M range, that is, whether or not the M range switch 25 is on (S46). If S46; No, the process returns. If S46; Dt ≦ DT (for example, DT = 1 second) is determined (S47), S47; if No, Tt1 is set to TtA (S48), and if S47; Yes, Tt2 is set to TtA ( S49), each returns.

  That is, when an operation is performed to switch the shift lever 1 from the P (or N) range to the M range via the D range, the driver moves the shift lever 1 from the P (or N) range to the D range. Although there is a high possibility that switching to the range has been made, and there is a high possibility of switching to the M range by passing through the D range due to an erroneous operation. In this case, when the automatic transmission is in the manual shift mode at an early stage, It can be determined that the shift speed is inappropriate.

This M range erroneous operation determination processing is adopted in the third and fourth embodiments, and in the manual shift operation inappropriate determination processing, in the case of the third embodiment, the set high rotational speed integral value IRA is determined as negative in the M range erroneous operation determination processing. In this case, when the predetermined first set high rotational speed integral value IR1 is adopted and an affirmative determination is made in the M range erroneous operation determination process, the second set high rotational speed integral value lower than the first set high rotational speed integral value IR1. In the case of Example 3, in the case of Example 3, when the negative determination is made in the M range erroneous operation determination process as the set fuel cut number CfA, the predetermined first set fuel cut number Cf1 is adopted and the positive determination is made in the M range erroneous operation determination process. In this case, the second set fuel cut number Cf2 lower than the first set fuel cut number Cf1 is adopted.
[Reference Example 2]

The reference example 2 changes the notification control of the first embodiment . In this notification control, as shown in FIG. 16, S50 to S53 similar to S1 to S4 in FIG. 6 of the first embodiment are executed, and after S53, the non-operation time t of the shift lever 1 is counted (S54). ). Note that the second embodiment or the third embodiment may be employed for the manual shift operation inappropriateness determination process of S1.

After S54, it is determined whether or not the D range switch 24 is on (S55). If S55; No, it is determined whether or not the upshift and downswitches 26 and 27 are on (S56). S56; If No, it is determined whether or not the non-operation time t counted in S54 is equal to or longer than a set time Ct (for example, 10 seconds) (S57). If S57; No, the process returns to S54 and the non-operation time t Will continue to count. Similarly to the first embodiment , if S55; Yes or S56; Yes, the operation guidance being executed in S53 is terminated (S58), and the process returns.

  On the other hand, when the non-operation time t is equal to or longer than the set time Ct (S57; Yes), the shift mode of the automatic transmission is forcibly switched from the manual shift mode to the automatic shift mode (S60). A mode forcible switching instruction is output to the machine control system 29 and executed, and notification that this forcible switching has been performed is given (S60). In this case, as shown in FIG. 17, for example, “forcibly switching to D mode” is displayed on the multi-display unit 18 together with the operation guidance.

  Thereafter, it is determined whether or not the D range switch 24 is on (S61). If S61; No, it is determined whether the upshift and down switches 26 and 27 are on (S62). If S62; Returning, the notification that the operation guidance and forced switching have been performed is continued. If S61: Yes, the notification executed in S53 and S60 is terminated (S64), and the process returns. If S62: Yes, the shift mode of the automatic transmission is returned to the manual shift mode (S63). In this case, a mode return instruction is output and executed to the automatic transmission control system 29, and thereafter, after executing S64, the process returns.

  After the notification of the switching operation guidance, the control unit 20 forcibly switches the shift mode of the automatic transmission from the manual shift mode to the automatic shift mode when no operation is performed by the driver according to the notification. Further, it is possible to reliably prevent an increase in the load on the engine and the engine exhaust system. In addition, the control unit 20 forcibly switches to the automatic transmission mode and then returns the manual transmission mode to the manual transmission mode when the shift operation is performed by the driver. Even if it is forcibly switched to the shift mode, the subsequent shift operation by the driver is performed, so that the manual automatic shift mode can be quickly and reliably met in response to the request to switch the shift step in the manual operation. Can be restored.

  The present invention can be applied to various automobiles and various automatic transmissions. For example, the present invention can be applied to a switch having the same function as the M range switch 25 and the upshift and downswitches 26 and 27 that can be operated on the steering wheel.
