Description

  The present invention relates to a vehicle notification device with an automatic transmission, and in particular, when the automatic transmission is in a manual shift mode, when the gear change by manual operation by a driver is unfamiliar, The present invention relates to a notification device that notifies a driver of a manual operation method for shifting 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 when the driver turns on the switch, the shift mode is switched to the manual shift mode. 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.

JP 2006-273111 A

  In the vehicle with the automatic transmission, when the driver is unfamiliar with the operation including the gear shifting operation performed with respect to the manual transmission mode of the automatic transmission, as a typical situation, the automatic transmission is in the manual transmission mode. In this case, there is a possibility that the driver does not switch the gear position even though the gear position is switched and the driving state is appropriate. As described above, when the automatic transmission is in the manual shift mode and the gear change by manual operation by the driver is unskilled, the gear cannot be changed well, and the vehicle cannot be driven smoothly.

  Further, when the shift mode of the automatic transmission is switched to the manual shift mode by an erroneous operation, or when the shift mode of the automatic transmission is switched to the manual shift mode, this may happen. In this case as well, the gears cannot be switched well, and there is a possibility that the vehicle cannot be driven smoothly. However, in such a situation, the operation performed by the driver for the manual transmission mode of the automatic transmission is not familiar. It is considered that it is likely to occur in some cases.

  Here, if it is possible to detect that the shift of the gear position by manual operation by the driver is inexperienced when the automatic transmission is in the manual transmission mode, it may be possible to notify the driver of this. In addition to the problem that it is very difficult to detect the vehicle, it is possible to reliably improve the problem that even if the driver is simply inexperienced, the gear cannot be switched well and the vehicle cannot be driven smoothly. Not a translation.

  In particular, if the driver does not switch the shift stage to the shift-up side even though the shift stage is switched to the shift-up side, the engine speed increases unnecessarily. There is a risk of running the vehicle for a long time in a state, and fuel cut to the engine may be performed, so the load on the engine and the engine exhaust system increases and the exhaust gas also increases, which is not good for the global environment .

  An object of the present invention is to operate a manual operation method for shifting gears in the manual gear shifting mode when the vehicle is stopped, when the automatic gear shifting is in the manual gear shifting mode and the gear shifting by manual operation of the driver is not familiar. In this case, make sure that the driver is not proficient or not, and enable the driver to properly perform the manual operation of the gear shift in the manual gear shift mode, so that the vehicle can switch the gear to a good level. It is an object of the present invention to provide a notification device for a vehicle with an automatic transmission that can smoothly operate the engine and prevent an increase in the load on the engine and the engine exhaust system.

  According to a first 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 that includes 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, and a notification control means that controls the notification means, When the automatic transmission is in the manual shift mode, the notification control means has a determination means for determining whether or not the shift of the gear position by the manual operation of the driver is unfamiliar. When the vehicle is stopped, the driver is informed of a manual operation method for shifting gears in the manual shift mode.

  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 unskilled when the automatic transmission is in the manual shift mode. When an affirmative determination is made, the notification control means controls the notification means when the vehicle is stopped, and the notification means notifies the driver of the manual operation method for shifting the gear in the manual shift mode.

  In particular, when the driver is not accustomed to the operation including the gear change operation performed for the manual transmission mode of the automatic transmission, as a typical situation, when the automatic transmission is in the manual transmission mode, However, there is a possibility that the driver does not change the gear position even though the vehicle is in the appropriate running state. Thus, the gear position manually operated by the driver when the automatic transmission is in the manual gear shift mode. If the switching of the vehicle is unskilled, the driver can reliably perform an appropriate operation by notifying the manual operation method.

Here, the following configuration can be adopted as a dependent claim of claim 1.
A driving state detecting means for detecting one or a plurality of physical quantities that reflect the driving state of the vehicle is provided, and the judging means switches the gear position based on the physical quantity detected by the driving state detecting means and is appropriately unskilled driving. When it is determined whether or not the vehicle is in a state, the unskilled driving state value is cumulatively calculated from the time or the number of times the vehicle has been in the unskilled driving state, and the unskilled driving state value exceeds a predetermined threshold value. The affirmative judgment is made that the person is unskilled (claim 2).

  The plurality of physical quantities includes a vehicle speed and an engine throttle opening, and the determination means corresponds to a shift map corresponding to a shift map for determining a gear position based on the vehicle speed and the engine throttle opening in the automatic shift mode. A proficiency determination map having an inexperienced determination map in which an inexperienced zone corresponding to each gear position is determined, and the inexperienced running state value is determined based on the vehicle speed and the engine throttle opening degree. This is the time spent in the unskilled zone corresponding to the current gear position. The determination means resets the unskilled running state value when the shift mode of the automatic transmission is switched to the automatic shift mode.

  The shift lever of the automatic transmission is configured to switch from a non-traveling range to a manual range for selecting a manual shift mode via a drive range for selecting an automatic shift mode, and the notification control means A second determining unit configured to determine whether or not an operation for switching the lever from the non-traveling range to the manual range via the drive range is performed, and the determining unit includes the second determining unit; When a positive determination is made, a threshold value lower than a predetermined threshold value is used (claim 5). The notification means includes at least one of a display unit provided on an instrument panel and a sound generation unit for performing sound notification, and the notification control unit includes the manual operation on at least one of the display unit and the sound generation unit. The method is notified (claim 6).

  According to the notification device for a vehicle with an automatic transmission according to the first aspect, the notification control unit controls the notification unit that can notify the driver, and the determination unit of the notification control unit determines that the automatic transmission is in the manual shift mode. Sometimes it is determined whether or not the speed change by manual operation of the driver is inexperienced, and if the determination is affirmative, when the vehicle is stopped, the manual operation method of the speed change in the manual speed change mode is notified to the driver. Inform the means.

  Therefore, particularly when the driver is not familiar with operations including a gear change operation performed with respect to the manual transmission mode of the automatic transmission, as a typical situation, when the automatic transmission is in the manual transmission mode, Although the driver may not change the gear position even though the gear position is switched, the driver may not change the gear position. Thus, when the automatic transmission is in the manual gear shift mode, When the gear change is not familiar, the notification of the manual operation method ensures that the driver can perform an appropriate operation.

  In other words, the driver can switch the gear stage smoothly and can drive the vehicle smoothly, especially when the gear stage is switched to the upshift side and is in an appropriate running state, and the gear stage is shifted without delay. Since it can be switched to the up side, an unnecessary increase in the engine speed can be suppressed, and it is possible to prevent the vehicle from traveling for a long time while the gear position is at a low speed, and also it is possible to suppress fuel cut to the engine. Therefore, an increase in the load on the engine and the engine exhaust system can be prevented.

  According to the alarm device for a vehicle with an automatic transmission according to claim 2, the vehicle is provided with a traveling state detecting unit that detects one or a plurality of physical quantities reflecting the traveling state of the vehicle, and the determination unit is detected by the traveling state detecting unit. Based on the physical quantity, it is determined whether or not the gear is switched to an appropriate unskilled driving state, and an unskilled driving state value consisting of the time or the number of times the unskilled driving state is reached is cumulatively calculated. When the learning driving state value is equal to or greater than a predetermined threshold, an affirmative determination is made that the learning driving state value is not acquired. That is, the determination means of the notification control means corresponds to one or a plurality of physical quantities that reflect the running state of the vehicle, and switching of the gear stage by the driver's manual operation is inexperienced when the automatic transmission is in the manual shift mode. Therefore, if the engine operation is not preferable, it can be determined that the engine is unskilled, and if the engine operation is not preferable, the engine load is increased to some extent. Since it is possible to make a negative determination even in such a case, the notification of the switching operation method can be carried out with the minimum necessary, so that the driver (especially the driver who is known to have switched to the manual shift mode) is bothered. In such a manner, balanced notification can be performed.

  According to the vehicle notification apparatus with an automatic transmission according to claim 3, the plurality of physical quantities includes the vehicle speed and the throttle opening of the engine, and the determining means is based on the vehicle speed and the throttle opening of the engine in the automatic transmission mode. An unfamiliarity determination map corresponding to a shift map for determining a gear position, and having an unfamiliarity determination map in which an unfamiliar zone corresponding to each shift speed is determined. And the engine throttle opening is the time spent in the unskilled zone corresponding to the current gear position in the unskilled judgment map, so that the judgment means of the notification control means is the appropriate unskilled driving when the gear stage is switched. It is possible to reliably determine whether or not the state is in a state, and whether or not the gear shift by manual operation by the driver is inexperienced when the automatic transmission is in the manual shift mode.

  According to the notification device for a vehicle with an automatic transmission according to claim 4, the judging means resets the unskilled running state value when the shift mode of the automatic transmission is switched to the automatic shift mode. When the switch is made, the notification of the switching operation method is not performed as much as possible, so that the driver is not bothered.

  According to the notification device for a vehicle with an automatic transmission according to claim 5, a manual range in which a shift lever of the automatic transmission selects a manual transmission mode from a non-traveling range via a drive range for selecting an automatic transmission mode. And the notification control means includes second determination means for determining whether or not an operation for switching the shift lever so as to go straight from the non-traveling range to the manual range via the drive range is performed. The determination means uses a threshold value lower than the predetermined threshold value when the second determination means makes an affirmative determination, so that the shift lever switches from the non-traveling range to the manual range via the drive range. If a change operation is performed, the driver intends to switch the shift lever from the non-travel range to the drive range. In this case, when the automatic transmission is in the manual shift mode, it can be determined that the shift of the gear stage by the manual operation of the driver is inexperienced at an early stage. .

  According to the notification device for a vehicle with an automatic transmission according to claim 6, the notification means has at least one of a display section provided on the instrument panel and a voice generation section that reports by voice. Since at least one of the display unit and the sound generation unit is informed of the manual operation method, the manual operation method is surely notified to the driver, and this notification is performed by one of the display unit and the sound generation unit. The configuration of the notification means can be simplified, and if it is performed by both the display unit and the voice generation unit, the notification can be more reliably recognized by the driver.

  The alarm device for a vehicle with an automatic transmission according to the present invention includes a shift mode of the automatic transmission, an automatic shift mode in which the shift stage is automatically switched based on a predetermined shift characteristic, and a driver manually operating the shift stage. 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.

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.

  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. Switches 26A and 26B and shift down switches 27A and 27B are provided. 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 upshift and downswitches 26A and 27A are used to shift up the shift lever 1. The downshift operation can be detected respectively, and the upshift and downswitches 26B and 27B are provided on the steering wheel (not shown) and can detect the upshift operation and the downshift operation, respectively.

  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. The control unit 20 is based on detection signals received from the switches 21 to 25, 26A, 26B, 27A and 27B, and further based on signals received from the engine control system 28 and the automatic transmission control system 29. 16, the gear position display unit 17 and the multi display unit 18 are 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 the automatic transmission is in the manual shift mode, whether or not the shift of the shift stage by the manual operation of the driver is unskilled, and makes an affirmative determination, When the vehicle is stopped, the driver is informed of a manual operation method for shifting gears in the manual shift mode. Next, 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, the unfamiliarity determination process (S2, corresponding to determination means) is executed.

  The unfamiliarity determination process of S2 is a process of determining whether or not the gear shift by manual operation by the driver is unfamiliar when the automatic transmission is in the manual shift mode. In the first embodiment, the engine control system Based on a plurality of physical quantities (vehicle speed V, engine throttle opening θ) reflecting the running state received from the vehicle 28, it is determined whether or not the gear stage is switched and is in an unfamiliar running state. The inexperienced running state value (It) consisting of the time when has become cumulatively calculated, and when the unfamiliar running state value becomes equal to or greater than a predetermined threshold, an affirmative determination is made that the person is not familiar. A running state detecting means for detecting a plurality of physical quantities is provided in the engine control system 28.

  The control unit 20 that performs this unfamiliarity determination process is an unfamiliar determination corresponding to a shift map (see FIG. 9) for determining a gear position based on the vehicle speed V and the throttle opening θ of the engine in the automatic shift mode. An unfamiliarity determination map (a first speed unfamiliarity determination map in FIG. 10, a second speed unfamiliarity determination map in FIG. 11, a third speed unfamiliarity in FIG. 12). 13), and the unskilled driving state value (It) corresponds to the vehicle speed V and the throttle opening θ of the engine corresponding to the current gear position of the unskilled judgment map. It is time to stay in the unfamiliar zone.

  That is, in the unskilled determination process of S2, as shown in FIG. 7, first, the current gear stage S of the automatic transmission, the vehicle speed V, and the throttle opening degree θ of the engine are read (S10), and are read in S10. The inexperienced judgment map corresponding to the shift stage S is read (S11), and the vehicle speed V and the throttle opening θ read in S10 stay in the inexperienced zone of the inexperienced judgment map read in S11. It is determined whether or not (S12).

  Here, the automatic transmission of the present embodiment is a four-speed automatic transmission. As shown in FIG. 10, in the first-speed inexperienced determination map, the shift-up side (the higher vehicle speed side than the first-speed shift-up line) is shown. Only the inexperienced zone Sup1 is set. As shown in FIG. 11, in the 2nd-speed inexperienced judgment map, the inexperienced zone Sup2 on the shift-up side (the vehicle speed side higher than the 2nd-speed shift-up line) and the shift-down side (2 An inexperienced zone Sdown2 on the lower speed side than the speed downshift line) is set, and as shown in FIG. 12, in the 3rd speed inexperienced judgment map, on the upshift side (higher speed side than the 3rd speed upshift line) An inexperienced zone Sup3 and an inexperienced zone Sdown3 on the downshift side (lower vehicle speed side than the 3rd speed downshift line) are set. As shown in FIG. Only unskilled zone Sdown4 the low vehicle speed side) is set than fast downshift line.

  Then, as shown in FIG. 7, in the case of S12; Yes, the unskilled zone stay time It is timed (S13), and this unskilled zone stay time It is the set unskilled zone stay time Itc (for example, 10 minutes). Whether this is equal to or greater than a predetermined threshold value is determined (S14).

  If S12; No or S14; No, it is determined whether or not the mode has been switched to the automatic transmission mode (S16). If S16; Yes, S16; However, in the case of S16; Yes, the unskilled zone stay time It is reset to 0 (S17) and the process returns. If the operation returns without being determined to be unfamiliar with the operation, as shown in FIG. 6, since it does not become inexperienced (F = 1) (S3; No), the process returns to S1, and when S1; If it is repeatedly executed and S12; Yes, in S13, the inexperienced zone stay time It is timed and increases.

  On the other hand, as shown in FIG. 7, in the case of S14; Yes, it is determined that the operation is unskilled, the unskilled flag F is set to 1 (S15), and the process returns. Then, as shown in FIG. 6, it becomes unskilled (F = 1) (S3; Yes), and the manual operation method notification process (S4) is executed.

  In the manual operation method notifying process in S4, as shown in FIG. 8, first, it is determined whether or not the vehicle is stopped (S20). If S20 is Yes, an operation method including a manual operation method for shifting gears in the manual shift mode. Is notified (S21). In this case, the multi display unit 18 is controlled, and the screens shown in FIGS. 14 to 19 are displayed on the multi display unit 18 so as to be sequentially switched in the order of the drawings. The switching of these screens may be automatically performed at regular time intervals, or may be performed by a driver's operation. Then, when the last screen of FIG. 19 is displayed on the multi-display unit 18, the notification of the manual operation method is completed.

  That is, after S21, it is determined whether the notification is completed (S22). If S22; Yes, the unskilled flag F is reset to 0 (S23), and the process returns. In the case of S22; No, the process returns to S20, and in the case of S20; Yes, the notification of the manual operation method is continued in S21. In S20; No, it is determined whether or not the manual operation method is being notified (S24). In S24; No, the process returns to S20, and in S24; Yes, the notification of the manual operation method is interrupted (S25). Return to S20.

  After the interruption of the notification in S25, S20; Yes again, and when the manual operation method is notified in S21, the notification may be notified from the point of interruption, or the notification may be restarted from the beginning. May be. Note that a voice generation device (not shown) that notifies by voice may be added as the notification means, and the manual operation method may be notified by both the multi-display unit 8 and the voice generation device. In this case, although the screens of FIGS. 14 to 19 are sequentially displayed on the multi-display unit 18, the text corresponding to the displayed screen may be output by the display voice generator. In addition, it is good also as alert | reporting only by an audio | voice generator.

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 change by manual operation of the driver is inexperienced when the automatic transmission is in the manual shift mode. If the determination is affirmative, the multi-display unit 18 is informed to the driver of the manual operation method for shifting the gear position in the manual shift mode when the vehicle is stopped.

  Therefore, particularly when the driver is not familiar with operations including a gear change operation performed with respect to the manual transmission mode of the automatic transmission, as a typical situation, when the automatic transmission is in the manual transmission mode, Although the driver may not change the gear position even though the gear position is switched, the driver may not change the gear position. Thus, when the automatic transmission is in the manual gear shift mode, When the gear change is not familiar, the notification of the manual operation method ensures that the driver can perform an appropriate operation.

  In other words, the driver can switch the gear stage smoothly and can drive the vehicle smoothly, especially when the gear stage is switched to the upshift side and is in an appropriate running state, and the gear stage is shifted without delay. Since it can be switched to the up side, an unnecessary increase in the engine speed can be suppressed, and it is possible to prevent the vehicle from traveling for a long time while the gear position is at a low speed, and also it is possible to suppress fuel cut to the engine. Therefore, an increase in the load on the engine and the engine exhaust system can be prevented.

  A plurality of physical quantities (vehicle speed V, engine throttle opening θ) reflecting the running state of the vehicle are detected, and based on these physical quantities, it is determined whether or not the gear is switched to the appropriate unskilled running state. The unskilled driving state value (unskilled zone stay time It) consisting of the time when the unskilled driving state is reached is cumulatively calculated, and the unskilled driving state value is a predetermined threshold value (set unskilled zone stay time Itc). If it becomes the above, it is affirmed that it is unskilled.

  In other words, it is possible to reliably determine whether or not the gear change by manual operation of the driver is inexperienced when the automatic transmission is in the manual shift mode in correspondence with a plurality of physical quantities reflecting the running state of the vehicle, Therefore, if the engine operation is not preferable, it can be determined that the engineer is not familiar, and in cases other than the case where the engine operation is not preferable, a negative determination can be made even when the engine load increases to some extent. Since the notification of the switching operation method can be carried out with the minimum necessary, the driver (particularly, the driver who is aware that switching to the manual shift mode) is not bothered and balanced. Can be notified.

  An unskilled determination map corresponding to a shift map for determining a shift stage based on the vehicle speed V and the throttle opening θ of the engine in the automatic shift mode, and an unskilled zone corresponding to each shift stage is determined. Since there is an unskilled judgment map, the unskilled running state value is the time during which the vehicle speed V and the engine throttle opening θ stay in the unskilled zone corresponding to the current gear position of the unskilled judgment map. , Whether or not the shift stage is switched and it is determined whether or not it is in an unfamiliar driving state, and whether or not the shift stage by manual operation of the driver is inexperienced when the automatic transmission is in the manual shift mode It can be determined with certainty.

  When the transmission mode of the automatic transmission is switched to the automatic transmission mode, the unskilled driving state value is reset. Therefore, when the automatic transmission mode is switched, the notification of the switching operation method should be avoided as much as possible. Thus, the driver can be prevented from being bothered. If the notification of the switching operation method is performed by one of the multi display unit 18 and the sound generator, the configuration for the notification can be simplified, and if it is performed by both the multi display unit 18 and the sound generator, Thus, the notification can be more reliably recognized by the driver.

  The second embodiment is a modification of the inexperienced determination process of the first embodiment. In this unfamiliarity determination process, whether or not the gear stage is switched based on a plurality of physical quantities (vehicle speed V, engine throttle opening θ) reflecting the traveling state received from the engine control system 28 is an appropriate unfamiliar traveling state. The unskilled driving state value (unskilled zone switching number Ic) consisting of the number of times of becoming the unskilled driving state is cumulatively calculated, and the unskilled driving state value becomes a predetermined threshold value or more. If it is, the affirmative judgment is made that it is unskilled.

  The control unit 20 that performs the unfamiliarity determination process has an unfamiliarity determination map (see FIGS. 10 to 13) similar to that of the first embodiment, and the unskilled driving state value (Ic) includes the vehicle speed V and the engine. Is the number of times of switching from a zone other than the unskilled zone corresponding to the current gear position of the unskilled determination map to the unskilled zone.

  As shown in FIG. 20, this unfamiliarity determination process is obtained by changing S12 to S14 in FIG. 7, and after S11, the vehicle speed V and the throttle opening θ read this time in S10 are the previous values in S10. Unlike the vehicle speed V and the throttle opening θ read this time, it is determined whether or not the vehicle has been switched to staying in the unfamiliar zone in the unfamiliarity judgment map read in S11 (S32).

  S32: In the case of Yes, the unskilled zone switching number Ic is incremented to Ic + 1 (S33), and this unskilled zone switching number Ic is the set unskilled zone switching number Icc (for example, five times, which corresponds to a predetermined threshold value) It is determined whether or not (S34), S34; If Yes, the process proceeds to S15. If S32; No or S34; No, the process proceeds to S16.

  In the third embodiment, the control unit 20 determines whether or not the operation of switching the shift lever 1 from the P (or N) range to go straight to the M via the D range is performed. If the negative determination is made in the M range erroneous operation determination process as the set unlearned zone stay time Itc used in the unfamiliarity determination process of the first embodiment, the predetermined first unfamiliar zone stay is determined. When the time It1 is adopted and an affirmative determination is made in the M range erroneous operation determination processing, the second set unfamiliar zone stay time It2 that is lower than the first set unfamiliar zone stay time It1 is adopted.

  In this M range erroneous operation determination process, as shown in FIG. 21, 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, Itc is set to Itc (S48), and S47; If Yes, Itc is set to It2 ( 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 of the gear position is not yet mastered.

  Note that this M range erroneous operation determination process is adopted in the second embodiment, and in the unfamiliarity determination process, when a negative determination is made in the M range erroneous operation determination process as the setting unfamiliar zone switching frequency Icc, a predetermined first setting unfamiliar zone When the number of times of switching Ic1 is adopted and an affirmative determination is made in the M range erroneous operation determination process, a second setting unfamiliar zone switching number Ic2 lower than the first setting unfamiliar zone switching number Ic1 may be adopted.

  The inexperienced determination process of the first embodiment and the inexperienced determination process of the second embodiment are performed in parallel, and when at least one of the unfamiliarity determination processes determines that the operation has not been performed, the manual operation method notification process in S4 Or the manual operation method notifying process of S4 is executed only when both of these unskilled determination processes are determined to be unskilled operations.

  In addition, in the unfamiliarity determination process of S2, at least one of the engine speed, the engine exhaust temperature, the engine coolant temperature, and the number of engine fuel cuts is detected as one or a plurality of physical quantities, and based on this physical quantity Judgment is made as to whether or not the gear stage has been changed and the vehicle is in an unfamiliar driving state, and an unfamiliar driving state value consisting of the time or number of times the vehicle has been in the unfamiliar driving state is cumulatively calculated. May be affirmatively determined to be inexperienced when the value exceeds a predetermined threshold.

  It should be noted that the present invention can be implemented with various modifications other than those disclosed above, and the present invention can be applied to various automobiles and various automatic transmissions.
