Description

  The present invention relates to an alarm device for a vehicle with an automatic transmission, and in particular, when an operation for switching the shift lever from a non-traveling range to a manual range via a drive range is performed, the shift lever is manually operated. The present invention relates to a notification device that notifies that the switching to the range is emphasized more than usual.

  Conventionally, in a vehicle with an automatic transmission, a shift lever for selecting a shift range of the automatic transmission has been changed via a drive range in which a shift stage is automatically switched from a non-driving range based on a predetermined shift characteristic. A configuration in which the driver switches to a manual range in which the gear position can be switched manually is provided (see, for example, Patent Document 1).

  In vehicles with this type of automatic transmission, when the driver switches the shift lever from the non-traveling range to the manual range via the drive range, the driver often switches to the drive range and then switches to the manual range. In addition, after switching to the manual range, the drive range and the manual range may be switched alternately.

  The shift lever stays in the non-running range when the engine is started or when the shift lever is returned to the non-running range when the vehicle is temporarily stopped, and then the above operation is performed. . Here, the shift range in which the shift lever is switched is generally displayed on a shift range display (for example, any of the indicators “P”, “R”, “N”, “D”, and “M” is lit) In the case of the range, “M” is turned on)).

JP 2006-273111 A

  In the vehicle with the automatic transmission, there is a possibility that the driver intends to switch the shift lever from the non-traveling range to the drive range, but switches to the manual range by passing through the drive range by mistake. In this case, the fact that the shift lever has been switched to the manual range is displayed on a general shift range display (for example, “M” is lit). If you do not notice is considered.

  The driver then depresses the accelerator pedal to drive the vehicle, assuming that the shift lever has been switched to the drive range, but in reality the shift lever has been switched to the manual range, so that the gear position is low ( (Normally 1st gear), the engine speed increases unnecessarily, and there is a risk that the vehicle will run for a long time with the gear stage kept at a low speed, and fuel cut to the engine may be performed. The load on the engine and engine exhaust system increases and the exhaust gas also increases, which is not good for the global environment.

  Therefore, it can be considered that the above problem is addressed by giving a notice that the shift lever has been switched to the manual range, which is emphasized rather than a general display. In this case, in particular, there is a high possibility that the trouble that the driver who switched the shift lever to the manual range knows will become large, and depending on the degree of emphasis of the notification, the driver may be supported. It may develop into the problem that the environment inside the car deteriorates.

  The object of the present invention is to notify the fact that the shift lever has been switched to the manual range only when there is a possibility that the switching operation is erroneous, to prevent an increase in the load on the engine and the engine exhaust system, etc. In addition, the emphasis notification is appropriately performed according to the situation so that the driver is not bothered, and the normal notification and the emphasis notification can be performed in a balanced manner. It is to provide a notification device.

  According to a first aspect of the present invention, there is provided a notification device for a vehicle with an automatic transmission in which a shift lever for selecting a shift range of the automatic transmission is automatically switched from a non-travel range based on a predetermined shift characteristic. Notifying that the shift lever has been switched to the manual range in a vehicle with an automatic transmission configured so that the driver can switch to a manual range in which the gear position can be manually switched via the range. And a notification control means for controlling the notification means, wherein the notification control means is operated to switch the shift lever from the non-running range to the manual range via the drive range. A determination means for determining whether or not, and if this determination means makes a negative determination, the notification means is notified in a predetermined first notification mode, If the disconnection unit is affirmative determination is characterized in that to inform the informing means in second notification aspects emphasized than the first notification manner.

  In this vehicle notification apparatus with an automatic transmission, it is determined by the determination means of the notification control means whether or not an operation for switching the shift lever from the non-traveling range to the manual range via the drive range has been performed. If the affirmative determination is made, the driver intends to switch the shift lever from the non-travel range to the drive range, but there is a possibility that the drive range has been switched to the manual range due to an erroneous operation. It is probable that the driver switched the shift lever to the manual range with the knowledge of the driver.

  Then, the notification means for notifying that the shift lever has been switched to the manual range is controlled by the notification control means, and when the determination means makes a negative determination, the notification means notifies the predetermined first notification mode. If the determination means makes an affirmative determination, the notification means notifies the second notification mode that is more emphasized than the first notification mode. In particular, when the driver switches the shift lever to the manual range due to an erroneous operation, this can be quickly and reliably noticed by the notification in the second notification mode, and the shift lever can be switched to the drive range without delay, An unnecessary increase in the engine speed can be suppressed by manually switching the gear position in the state of switching to the range.

Here, the following configuration can be adopted as a dependent claim of claim 1.
The determining means has time measuring means for measuring the time spent in the drive range when the shift lever is switched from the non-traveling range to the manual range, and the time measured by the time measuring means is equal to or less than a set time. In this case, an affirmative decision is made (claim 2). The notification means includes a display unit provided on the instrument panel and a second display unit different from the display unit, and the notification control unit causes the first notification mode to be executed only by the display unit. The second notification mode is executed on both the display unit and the second display unit (Claim 3).

  The notification means includes a display unit provided on an instrument panel and a sound generation unit that notifies by sound, and the notification control unit causes the display unit to execute a first notification mode, and the display unit And a 2nd alerting | reporting aspect is performed by both a sound generation part (Claim 4). The notification means has a display unit provided on the instrument panel, and the notification control means alternatively uses the display unit to change the display mode between the first notification mode and the second notification mode. (Claim 5).

  The notification control means terminates the notification in the second notification mode when the shift lever is switched to the drive range in the state of being notified in the second notification mode or when the driver manually operates the gear position. (Claim 6). The notification control means makes a notification in the second notification mode only when the shift lever is switched to the manual range for the first time after the engine is started and when the determination means makes an affirmative determination (Claim 7).

  When the determination means makes an affirmative determination, the notification control means notifies in a predetermined first emphasis notification mode as the second notification mode, except when the shift lever is switched to the manual range for the first time after engine startup. When the shift lever is switched to the manual range for the first time after the engine is started, the second emphasis notification mode is further enhanced as the second notification mode (Claim 8).

  According to the notification device for a vehicle with an automatic transmission according to claim 1, the notification control means controls the notification means for notifying that the shift lever has been switched to the manual range, and the determination means of the notification control means includes: It is determined whether or not an operation for switching the shift lever from the non-running range to the manual range via the drive range has been performed, and when the determination is negative, the notification means is notified in a predetermined first notification mode, When an affirmative determination is made, the notification means is notified in the second notification mode that is more emphasized than the first notification mode.

  Therefore, if the driver intends to switch the shift lever from the non-travel range to the drive range, but there is a possibility that the drive range has been switched to the manual range due to an erroneous operation, the determination means will make a positive determination, The notification in the second notification mode can quickly and surely notify the driver, so that the driver can change the shift lever to the drive range or the manual range without delay. By switching the gear manually, unnecessary increase in engine speed can be suppressed, and the vehicle can be prevented from traveling for a long time while the gear is at a low gear, and fuel cut to the engine can be suppressed. As a result, the load on the engine and the engine exhaust system can be reduced, and an increase in exhaust gas can be reliably prevented.

  On the other hand, if the driver knows that the shift lever has been switched to the manual range, the determination means makes a negative determination to notify the first notification mode that the shift lever has been switched to the manual range. be able to. In other words, the emphasis notification is performed only when there is a possibility that the switching operation from the non-traveling range to the manual range via the drive range is erroneous, and the switching to the other manual ranges is performed in the normal first notification mode. Since the notification can be made, it is possible to perform a well-balanced notification between the normal notification and the emphasis notification without bothering the driver.

  According to the alarm device for a vehicle with an automatic transmission according to claim 2, the judging means has time measuring means for measuring the time during which the shift lever stays in the drive range when the shift lever is switched from the non-traveling range to the manual range. Since the affirmative judgment is made when the time counted by this timing means is less than the set time, whether or not the operation for switching the shift lever from the non-traveling range to the manual range via the drive range has been performed. Can be judged reliably.

  According to the notification device for a vehicle with an automatic transmission according to claim 3, the notification means includes a display unit provided on the instrument panel and a second display unit different from the display unit, and the notification control unit. Since the first notification mode is executed only by the display unit and the second notification mode is executed by both the display unit and the second display unit, the notification by the first notification mode and the first notification mode are emphasized. Thus, the notification in the second notification mode is distinguished and reliably performed, and in the second notification mode, the notification can be easily recognized by the driver.

  According to the notification device for a vehicle with an automatic transmission according to claim 4, the notification means includes a display section provided on the instrument panel and a sound generation section for performing sound notification, and the notification control means includes the display. Since the first notification mode is executed only by the unit and the second notification mode is executed by both the display unit and the sound generation unit, the same effect as in the third aspect can be obtained.

  According to the notification device for a vehicle with an automatic transmission according to claim 5, the notification means includes a display unit provided on the instrument panel, and the notification control unit includes a first notification mode and a second notification mode on the display unit. Are selectively executed by changing the display form. Therefore, the same effect as in the third aspect can be obtained by using only one display unit.

  According to the vehicle notification device with an automatic transmission according to claim 6, the notification control means is in a state where the notification is made in the second notification mode, when the shift lever is switched to the drive range, or when the driver shifts to the shift stage. Since the notification in the second notification mode is terminated when the is manually operated, the notification in the second notification mode can be appropriately terminated.

  According to the notification device for a vehicle with an automatic transmission according to claim 7, the notification control means is the second notification mode when the determination means makes an affirmative determination only when the shift lever is switched to the manual range for the first time after the engine is started. Therefore, if there is a possibility that the shift lever has been switched to the manual range, there is a possibility that the switching operation is erroneous. In such a manner, it is possible to perform a well-balanced notification between the normal notification and the enhancement notification so as to be notified in the first notification mode.

  According to the notification device for a vehicle with an automatic transmission according to claim 8, when the determination means makes an affirmative determination, the notification control means is in a case other than when the shift lever is switched to the manual range for the first time after starting the engine. When the second lever is switched to the manual range for the first time after the engine has been started as a second notification mode and the shift lever is switched to the manual range, the second notification mode is further emphasized than the first highlight mode. Since the notification is made in the 2 emphasis notification mode, if the shift operation is switched to the manual range and the switching operation may be erroneously operated, after the engine is started and the notification is made in the second emphasis notification mode, the driver In order not to bother the user, it is possible to perform a well-balanced notification in the enhancement notification by informing in the first enhancement notification mode. That.

  The vehicle notification device with an automatic transmission according to the present invention has a drive range in which a shift lever for selecting a shift range of the automatic transmission is automatically switched from a non-running range based on a predetermined shift characteristic. Thus, the present invention is applied to a vehicle with an automatic transmission configured so that the driver can switch to a manual range in which the gear position can be switched manually.

  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. The P range and N range correspond to the non-traveling range. In the D range (drive range), the shift stage of the automatic transmission is automatically switched based on a predetermined shift characteristic. In the M range (manual range), the operation is performed. The user can switch the gear position of the automatic transmission 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. As described above, 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 FIG. 4, the shift range display unit 16 displays the selected shift range of the automatic transmission. For example, “P” “R” “N” “D” “ The indicator lamps 16a to 16e made of light emitting diodes of “M” are provided, 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.

  Here, the shift range display unit 16 ("M" indicator lamp 16e) and the multi-display unit 18 correspond to notification means for notifying that the shift lever 1 has been switched to the M range, and the shift range display unit 16 ( The “M” indicator lamp 16e) corresponds to the display unit, and the multi-display unit 18 corresponds to the second display unit. 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. The control unit 20 can control the shift range display unit 16, the shift stage display unit 17, and the multi display unit 18 based on detection signals received from these switches 21 to 27. The control unit corresponds to notification control means for controlling the notification means.

  In this notification device 5, in particular, the control unit 20 determines whether or not an operation for switching the shift lever 1 so as to go straight from the P (or N) range to the M range via the D range is performed. When a negative determination is made that the lever 1 has been switched to the M range, it is notified in a predetermined first notification mode, and when an affirmative determination is made, the second notification mode is emphasized over the first notification mode. It is comprised so that it may alert | report.

  In the first embodiment, as shown in FIGS. 6 and 4, the control unit 20 causes the first notification mode (M mode normal notification) to be executed only by the shift range display unit 16 and turns on the “M” indicator lamp 16 e. As shown in FIGS. 6 and 7, the second notification mode (M mode emphasis notification) is executed on both the shift range display unit 16 and the multi display unit 18 to light the “M” indicator lamp 16 e. Then, for example, “entered M mode” is displayed on the multi-display unit 18.

  Next, the M mode notification control executed by the control unit 20 will be described based on the flowchart of FIG. A program for executing the M mode notification control is stored in the computer ROM of the control unit 20.

  As shown in FIG. 8, when the M-mode notification control is started, after the initial setting, first, whether or not the shift lever 1 stays in the P (or N) range, that is, the P range switch 21 (or It is determined whether or not the N-range switch 23) is ON (S1). If S1; Yes, the process returns and enters the S1 standby state. At the start of the M-mode notification control, the shift lever 1 normally stays in the P (or N) range, and thus enters the S1 standby state.

  If S1; 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 (S2). If S2; Yes, the D range stay flag DF is set to 1. It is set (S3) and the D-range stay time t is measured (S4). If S2; No, it is determined whether or not DF = 1 (S5). If S5; No, the process returns. If S5; Yes, t measured in S4 is stored as Dt, and DF and t are 0. (S6).

  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 (S7). If S7; No, the process returns. If S7; , Dt ≦ DT (for example, DT = 1 second) is determined (S8). If S8; Yes, the M mode emphasis notification (S9) is executed, and if S8; No, the M mode is determined. Normal notification (S14) is executed.

  Here, S1 to S8 correspond to determination means for determining whether or not an operation for switching the shift lever 1 from the P (or N) range to the M range via the D range has been performed. S4 corresponds to time measuring means for measuring the time t during which the shift lever 1 stays in the D range when the shift lever 1 is switched from the P (or N) range to the M range.

  After S9, 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 (or the upshift switch or the shift provided on the steering wheel (not shown)). It is determined whether or not the down switch is on (S10). If S10; Yes, the M mode enhancement notification is terminated (S11), and the M mode normal notification (S14) is executed. In S10; 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 (S12). If S12; Yes, the M mode enhancement notification is terminated ( S13), return. In the case of S10; No, S12; No, the process returns to S10 and the M mode enhancement notification is continued.

  On the other hand, after S14, 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 (S15). If S15; Yes, the M mode normal notification is terminated ( S13), return. In the case of S15; No, the process returns to S15, enters the S15 standby state, and the M mode normal notification is continued.

The notification device 1 described above has the following effects.
The control unit 20 controls the shift range display unit 16 and the multi display unit 18 for notifying that the shift lever 1 has been switched to the M range, and the shift lever 1 passes through the D range from the P (or N) range. It is determined whether or not an operation for switching directly to the M range has been performed. When a negative determination is made, the shift range display unit 16 is notified in a predetermined first notification mode, and when an affirmative determination is made, the first notification mode is determined. The shift range display unit 16 and the multi display unit 18 are notified in the second notification mode that is more emphasized.

  Therefore, if the driver intends to switch the shift lever 1 from the P (or N) range to the D range, but there is a possibility that the driver has passed the D range and switched to the M range due to an erroneous operation, this is the case. 2 The notification by the notification mode can promptly and surely notify the driver, so that the driver can manually change the shift stage without switching the shift lever 1 to the D range or the M range without delay. It is possible to suppress an unnecessary increase in the engine speed by switching the operation, and to prevent the vehicle from traveling for a long time while the gear position is at a low speed, and also because the fuel cut to the engine can be suppressed. In addition, the load on the engine exhaust system can be reduced, and an increase in exhaust gas can be reliably prevented.

  On the other hand, when it is considered that the driver has switched the shift lever 1 to the M range with the knowledge of the driver, it can be notified in the first notification mode that the shift lever 1 has been switched to the M mode. That is, the emphasis notification is performed only when there is a possibility that the switching operation from the P (or N) range to the M range via the D range may be erroneously performed. Since the notification can be made in the notification mode, it is possible to provide a balanced notification between the normal notification and the emphasis notification without bothering the driver.

  When the shift lever 1 is switched from the P (or N) range to the M range, the time t staying in the D range is counted, and when this D range staying time Dt (= t) is equal to or shorter than the set time DT, Since it is determined that the operation of switching the shift lever 1 from the P (or N) range to the M range via the D range has been performed, this determination can be made with certainty.

  Since the control unit 20 causes the first notification mode to be executed only by the shift range display unit 16 and causes the second notification mode to be executed by both the shift range display unit 16 and the multi display unit 18, the notification by the first notification mode, It is possible to distinguish and reliably perform the notification in the second notification mode that is emphasized over the first notification mode, and in the second notification mode, the notification can be easily recognized by the driver.

  The control unit 20 terminates the notification in the second notification mode when the shift lever 1 is switched to the D range with the notification in the second notification mode or when the driver manually operates the shift stage. Therefore, the notification according to the second notification mode can be appropriately terminated.

  As shown in FIG. 9, the notification device 5A according to the second embodiment has a configuration in which the multi-display unit 18 according to the first embodiment is omitted, and a voice generation device 30 that notifies by voice is provided instead of the control unit 20A. However, the shift range display unit 16 and the sound generator 30 are controlled to change the M mode enhancement notification in the first embodiment.

  That is, as shown in FIG. 10, the control unit 20 </ b> A causes the first notification mode (M mode normal notification) to be executed only by the shift range display unit 16, the “M” indicator lamp 16 e is lit, and the shift range display unit 16 and the sound generation device 30 are both caused to execute the second notification mode (M mode emphasis notification), the “M” indicator lamp 16e is turned on, and the sound generation device 30, for example, “enters M mode”. Is output as audio. Similar to the first embodiment, the notification by the first notification mode and the notification by the second notification mode emphasized over the first notification mode are distinguished and reliably performed, and the driver is reliably recognized in the second notification mode. Easy notification can be made.

  As shown in FIG. 11, the notification device 5B according to the third embodiment has a configuration in which the multi-display unit 18 according to the first embodiment is omitted, and the control unit 20B controls the shift range display unit 16 so that the M according to the first embodiment. The mode emphasis notification and the M mode normal notification are changed.

  That is, as shown in FIG. 12, the control unit 20 </ b> B causes the shift range display unit 16 to selectively execute the first notification mode and the second notification mode by changing the display mode, thereby providing the first notification mode. Then, the “M” indicator lamp 16e is turned on, and the “M” indicator lamp 16e is blinked in the second notification mode. Alternatively, in the first notification mode, the “M” indicator lamp 16e is lit at the normal luminance. 2 In the notification mode, the “M” indicator lamp 16e is turned on with high luminance. As in the first embodiment, only one shift range display unit 16 is used to distinguish between the notification in the first notification mode and the notification in the second notification mode that is emphasized over the first notification mode. In the second notification mode, the notification can be surely easily recognized by the driver.

  As shown in FIG. 13, the notification device 5 </ b> C according to the fourth embodiment has a configuration in which an ignition switch 31 is added to the configuration of the notification device 5 according to the first embodiment, and the detection received by the control unit 20 </ b> C from the switches 21 to 27 and 31. Based on the signal, the shift range display unit 16 and the multi-display unit 18 are controlled, and as shown in FIG. 14, the M mode notification control executed by the control unit 20C is basically performed in S30 to S34 in the flowchart of FIG. Will be added.

  As shown in FIG. 14, when this M-mode notification control is started, after the initial setting, it is first determined whether or not the ignition switch 31 is on (S30). S30; It will be in a standby state. S30: If Yes, the engine start flag EF is set to 1 (S31), then it is determined whether EF = 1 (S32). If S32; Yes, the process proceeds to S1, basically, Although the same control as in the first embodiment is performed, after S7, EF is reset to 0 (S33), the process proceeds to S8, and after S13, the process returns to S1.

  On the other hand, if S32; No, it is determined whether or not the shift lever 1 has been switched to the M range, that is, whether the M range switch 25 is on (S34). If S34; In the case of Yes, M mode normal notification (S14) is executed, and basically the same control as in the first embodiment is performed, but after S13, the process returns to S1.

  In this notification device 5C, the control unit 20C goes straight from the P (or N) range to the M range via the D range only when the shift lever 1 is switched to the M range for the first time after engine startup. When it is determined that an operation for switching to be performed is performed, the notification is made in the second notification mode. Therefore, when the shift lever 1 is switched to the M range, if there is a possibility that the switching operation is erroneous, the driver will not be bothered after informing in the second notification mode after starting the engine. In addition, it is possible to perform a well-balanced notification between the normal notification and the emphasis notification in the first notification mode.

  Note that S33 may be executed after S9 instead of after S7. Thus, after S31, EF is not reset to 0 unless M9 emphasis notification of S9 is performed. Therefore, the shift lever 1 is not limited to the case where the shift lever 1 is switched to the M range for the first time after the engine is started. When it is determined that an operation for switching from the P (or N) range to the M range via the D range is performed, the M mode emphasis notification is always performed at the first time. it can.

  As shown in FIG. 15, the notification device 5D according to the fifth embodiment has a configuration in which a sound generation device 30 and an ignition switch 31 are added to the configuration of the notification device 5 according to the first embodiment, and the control unit 20D includes switches 21 to 27. , 31 is used to control the shift range display unit 16, the multi-display unit 18, and the sound generator 30, and the M mode notification control executed by the control unit 20D as shown in FIG. Further, S9 in the flowchart of FIG. 8 is omitted, and S40 to S45 are added to the flowchart.

  As shown in FIG. 16, when the M-mode notification control is started, after the initial setting, it is first determined whether or not the ignition switch 31 is on (S40). S40; It will be in a standby state. S40: If Yes, the engine start flag EF is set to 1 (S41), the process proceeds to S1, and basically the same control as in the first embodiment is performed, but after S8, whether EF = 1 or not. Is determined (S42).

  If S42: Yes, M mode second emphasis notification (S43) is executed, EF is reset to 0 (S44), and the process proceeds to S10. If S42; No, M mode first emphasis notification (S45) is executed. ) Is executed, the process proceeds to S10, and after S13, the process returns to S1.

  Next, in the case of S50; Yes, the switching time counting permission flag MtF is reset to 1 (S51), and the process returns. In S50; No, it is determined whether or not MtF = 1 (S51). In S51; No, the process returns. In S51; Yes, the M range switching time t is measured (S53). 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 (S54). If S54; No, the process returns to S53.

  S54: If Yes, t counted in S53 is stored as Mt, and MtF and t are reset to 0 (S55). Next, it is determined whether or not Mt ≦ MT (for example, MT = 1 second) (S56). If S56; Yes, M mode enhancement notification (S9) is executed. If S56; No, M mode normal notification is performed. (S14) is executed, and S9 to S15 similar to those in the first embodiment are executed. After S13, the process returns to S50. Thus, it is possible to reliably determine whether or not an operation for switching the shift lever 1 from the P (or N) range to the M range via the D range is performed.

  In Examples 1 to 6, various notification modes (display mode, voice mode) can be adopted for the M mode normal notification (first notification mode) and the M mode enhancement notification (second notification mode). In addition, the path where the shift lever is switched from the P (or N) range to the M range via the D range is not limited to the zigzag path as shown in FIGS. The present invention can be applied. The present invention can be implemented with various modifications other than the disclosed items, and can be applied to various automobiles and various automatic transmissions.
