- Fig. 1 is a schematic diagram of a vehicle in which a manual transmission is connected to a gasoline injection engine.
- the torque required by the driver is determined by the accelerator opening (accelerator pedal depression amount) detected by the accelerator sensor 3 2.
- the engine controller 3 1 detects this accelerator opening and the crank angle sensor 3 3.
- the required torque is calculated based on the engine rotational speed N e, the target air amount and the target equivalence ratio are determined so that the required torque can be obtained, and the target air amount can be obtained via the throttle device 2 2.
- the amount of intake air taken into the engine is controlled, and the fuel injection amount is controlled via the injector 21 so that the target equivalence ratio is obtained.
- the above-mentioned throttle device 2 2 comprises an intake throttle valve 2 3 and a throttle motor 24 that drives this intake throttle valve, etc., and is adjusted by the intake throttle valve 2 3 so that a target air amount can be obtained.
- the stored air is stored in the intake collector 2 and then introduced into the combustion chamber 5 of each cylinder through the intake manifold 3.
- the fuel injection amount determined so as to obtain the target equivalence ratio is intermittently supplied into the intake port from the fuel injection valve 21 disposed in the intake port 4 of each cylinder at a predetermined timing. Specifically, the basic fuel injection amount required per engine revolution is calculated according to the intake air amount detected by the air flow meter 3 4 and the engine speed detected by the crank angle sensor 3 3. The fuel injection amount is obtained by multiplying the fuel injection amount by the target equivalence ratio.

- the exhaust passage 8 has a three-way catalyst 9.
- the three-way catalyst 9 can efficiently remove H C, C O and N O X contained in the exhaust gas simultaneously when the air-fuel ratio of the exhaust gas is in a narrow range centered on the stoichiometric air-fuel ratio. For this reason, the engine controller 31 performs feedback control of the air-fuel ratio based on a signal from the 02 sensor 36 provided upstream of the three-way catalyst 9.
- the engine configured as described above is connected to a manual transmission 51 having a forward five-speed gear, and the rotational speed of the drive shaft 52 is determined by a gear ratio determined by the gear of the manual transmission 51.
- the power of the drive shaft is finally transmitted to a wheel (not shown) so that the vehicle travels. If it is possible to convey to the driver information on which driving speed the manual transmission 5 1 will drive to optimize the driving fuel efficiency, the driver himself / herself performs a gear shifting according to that information, thereby reducing the driving fuel efficiency. Can be optimized. For this reason, the cab is provided with a display device 53 for instructing the upshift timing.
- This display device 5 3 consists of four indicator lights 5 3 a, 5 3 b, 5 3 c, and 5 3 d, and the upshift vehicle speed VSP 1 2 from the 1st speed to the 2nd speed.
- the 1st indicator lamp 5 3 a shift up timing indicating means
- D 2 3 the predetermined delay time
- D 2 3 the predetermined delay time
- the catalyst may depend on the water temperature at startup (state at startup), such as when the temperature at startup is 120 ° C or 20 ° C. Since the time until the activation of 9 is greatly different, the vehicle speed VSP 1 2 and the predetermined delay time D 1 2 are uniformly matched from the first to the second when the engine warm-up is completed. Therefore, when the start-up water temperature is lower than the start-up water temperature when the shift-up vehicle speed VSP 1 2 and the delay time D 1 2 are adapted, the conforming value does not match, the conforming value of the up-shifting vehicle speed is too low and the The delay time of the compliance value is too short, and early activation of the catalyst 9 cannot be performed sufficiently.
- upshift vehicle speed VSP 1 2 and delay time When starting at a temperature higher than the starting water temperature when D 1 2 is adapted, the corresponding value is shifted up, the vehicle speed is too high and the delay time of the adapted value is too long, and the catalyst 9 has already been activated. However, it will unnecessarily delay the shift-up to the 2nd speed, resulting in poor driving fuel consumption.
- the upshift vehicle speed VSP 1 2 from the 1st speed to the 2nd speed and the predetermined delay time D 1 2 after reaching the upshift vehicle speed VSP 1 2 Set according to the status.
- FIG. 2 is executed repeatedly at regular intervals (for example, every 100 msec).
- step 1 it is checked in step 1 whether or not the cranking is started based on a signal from a status switch (not shown). If the signal from the starter switch is ON, it is determined that the cranking is started, and the process proceeds to step 2. Based on the water temperature detected by the water temperature sensor 35 at that time, that is, the starting water temperature TWINT, Shift-up vehicle speed to 2nd speed VSP 1 2 and delay time D 1 2 until a command to shift up from 1st speed to 2nd speed after exceeding the specified speed is set.
- Fig. 3 an example of setting up the shift-up vehicle speed VSP 1 2 and the delay time D 1 2 is shown in Fig. 3.
- the shift-up vehicle speed VSP 1 2 is 15 km / h and the delay time is Assuming that D 1 2 is 1 sec, before the engine warm-up is completed, the lower the starting water temperature TW INT, the higher the shift-up vehicle speed VSP 1 2 and the lower the starting water temperature TW INT, the delay time D 1 Make 2 longer.
- the water temperature at start-up is 20 ° C
- the shift-up vehicle speed VSP 12 is 20 km / h, which is higher than 15 kmZli, which is the value after completion of the engine warm-up, and the delay time.
- D 1 2 is set to 3 sec, which is also longer than I sec, which is the value after the completion of the engine dredger.
- the starting water temperature is lower than 20 ° C. No 0.
- the shift-up vehicle speed VS P 12 is increased to 25 kmZh, and the delay time D 12 is increased to 5 seconds.
- step 5 the gear stage that the driver will select is estimated based on the engine rotational speed Ne detected by the crank angle sensor 33 and the actual vehicle speed VS P detected by the vehicle speed sensor 38. For example, a shift map of a tendency that the driver is likely to select is created in advance using the engine rotation speed Ne and the actual vehicle speed VSP as parameters, and the shift map that the driver will select is searched by searching the shift map. Estimate the stage.
- Step 6 it is checked whether the 1st speed is selected based on the estimation result.
- the routine proceeds to step 7 where the actual vehicle speed V SP is compared with the upshift vehicle speed VSP 1 2 set based on the starting water temperature TWI NT in step 2. If the actual vehicle speed VS P has reached the upshift vehicle speed VS P 12, proceed to step 8 and turn on the 1st indicator light 53a of the display device, and it is time to shift from 1st gear to 2nd gear. Tell the driver that. If the actual vehicle speed VSP has not arrived at the upshift vehicle speed VSP 12, go to step S9 and compare with the value after completion of engine warm-up, 15 km / h. If the actual vehicle speed VSP has not reached 15 km / h, proceed to steps 12 and 13 to reset the timer T to zero, keep the first indicator light 53a of the display device off, and perform the current process. finish.
- step 10 If the actual vehicle speed VS P exceeds 15 km / h after the engine warm-up is completed, proceed to step 10 to increment timer T from zero.
- This timer T is used to measure the elapsed time after the actual vehicle speed VS P reaches 15 km / h, which is the upshift vehicle speed after the engine warm-up is completed.
- step 12 the timer T is compared with the delay time D12. Immediately after the actual vehicle speed VSP reaches 15 KmZh, which is the upshift vehicle speed after the completion of the engine, the timer is less than the delay time D 1 2, so proceed to step 13 and the first indicator light on the display device 53 Keep “a” off and end the current process.
- step 10 Even if the actual vehicle speed VS P is the shift-up vehicle speed VSP 12 or less from the next time onward, if the shift-up vehicle speed after engine warm-up is 15KmZh or more, the timer T count-up operation in step 10 will not be performed. Since it is repeated, the timer T will eventually exceed the delay time D12. At this time, the process proceeds from step 8 to step 11 to turn on the first indicator lamp 53a of the display device, instructing that it is time to shift up from the first speed to the second speed.
- step 6 the process proceeds from step 6 to step 14, and the shift-up vehicle speed VS P 23 and the actual vehicle speed VSP from the second speed to the third speed reach this shift-up vehicle speed VSP 23.
- the predetermined delay time from the second gear to the third gear is instructed to shift up to D 23, the third gear up to the fourth gear VS P 34, the actual vehicle speed VSP reaches this vehicle speed VS P 34
- the predetermined delay time from the 3rd speed to the 4th speed until the shift up command is issued D 34, the 4th speed up to the 5th speed VSP 45, the actual speed VS P reaches this speed VS P4 5
- the 2nd, 3rd, 4th indicator lights 53b, 53c, 53d of the display device are turned off. Controls lighting.
- the shift-up vehicle speeds V S P 23, V S P 34, V S P 45 and the predetermined delay times D 23, D 34, D 45 are all fixed values.
- the lower the starting water temperature TW I NT, the higher the shift-up vehicle speed VS P 1 2 and the predetermined delay time D 1 2 The reason for this is that the lower the start-up water temperature TWI NT, the longer the time until the catalyst 9 is activated.
- Step 3 compare the catalyst temperature TCAT detected by the catalyst temperature sensor 37 with the predetermined catalyst activation temperature T0.
- the butterfly temperature TC AT reaches the catalyst activation temperature T 0 or higher (catalyst activity I 1 in the live state)
- the process proceeds from step 3 to step 4 to shift the vehicle speed from 1st gear to 2nd gear VSP 1 2 and the specified delay
- the time D 1 2 to the value after the engine warm-up is completed, that is, the normal set value, and perform the steps 5 to 12 to instruct the shift-up timing at the normal time after the engine warm-up is completed.
- the engine warm-up completion condition is determined by determining whether or not the catalyst is activated from the temperature of the catalyst 9, but the embodiment is not limited to this.
- the exhaust temperature TE XH at the engine outlet or the catalyst inlet is estimated based on the engine operating conditions (engine load and rotational speed), and whether the catalyst 9 is activated based on the exhaust temperature TEXH is determined. You may make it judge. Further, it may be determined that the engine warm-up has been completed based on the temperature of the engine cooling water having risen a predetermined temperature immediately after starting the engine.
- the shift-up vehicle speed VSP 1 which is determined according to the water temperature at startup, is set to 2 O Km / h, for example. Until the vehicle speed is exceeded, the first indicator light 5 3a cannot be switched from off to on, so the driver can be instructed to increase the engine speed in response to cold.
- the first indicator light 5 3 a will turn off if the specified time elapses exceeding 15 Km / 7 h. Is switched to lighting. This prevents the driver from feeling uncomfortable when, for example, the vehicle continues to run at 18 KmZh, but the speed change command is not given no matter how long it has exceeded 15 Km / h, which is usually commanded.
- FIG. 4 shows the case where the vehicle starts running after the engine warm-up is completed while the water temperature TWI NT at the start is the same 20 ° C.
- the model shows the difference between the change in the catalyst temperature TCAT (see the two-dot chain line) and the change in the catalyst temperature TCAT (see the solid line) when the vehicle starts running immediately after the engine starts. Since it is a model, the vehicle speed increases linearly.
- the bottom line shows what happens when the shift-up timing from 1st to 2nd is changed.
- the two-dot chain line shows the engine. This is when the vehicle starts running after the warm-up is completed.
- Shift-up vehicle speed VSP 1 2 from 1st speed to 2nd speed is determined by the water temperature TW INT at the start, and in this case the water temperature TW I NT at the start is 20 ° C, so the shift-up vehicle speed VS P 1 2 is 20 km / h It is higher than 15 km / h, which is the normal value after engine warm-up.
- the gear change command is not issued until 2 OKmZh, which is higher than the normal value of 15 Km / h after completion of engine warm-up. If the driver does not shift to this timing, the catalyst temperature TCAT can be quickly increased as shown by the solid line, and the activation temperature TO is reached at the timing of t3. Since it is judged that the vehicle has been completed, the upshift vehicle speed VSP 12 is returned from 20 km / h to 15 kmZh at the timing of t 3. At the timing of t3, the actual vehicle speed VS P is the upshift vehicle speed VS P 12.
- the first indicator light 53 a lights up at the timing of t 3 and it is instructed that it is time to shift up from 1st gear to 2nd gear. (See solid line). If the catalyst temperature T CAT rises as indicated by the one-dot chain line, the shift-up instruction is t 4 when the vehicle speed exceeds 2 OKmZh. Although not shown in the time chart of Fig.
- the first indicator lamp 53a lights up even if the vehicle speed 2 OKmZh is not exceeded, and it is instructed that it is time to shift up from 1st gear to 2nd gear. This can prevent the driver from feeling uncomfortable that the shift-up instruction is not issued at any time after the normal shift-up instruction of 15 KmZh is exceeded.
- the vehicle starts to run at the timing of t6 the engine warm-up is completed before that.
- the catalyst temperature T CAT gradually rises as indicated by the two-dot chain line, and the activation of the catalyst 9 is completed at the timing of t 5, so the shift-up vehicle speed VS P 1 2 is 20 kmZh at the timing of t 5 To 15 km / h (see the dashed line at the top).
- the first indicator lamp 53a lights up, indicating that it is time to shift up from 1st gear to 2nd gear (see the two-dot chain line at the bottom).
- the shift-up vehicle speed VS P 12 from the first speed to the second speed and the shift-up vehicle speed VS P 12 (15 Km / h) set after the engine warm-up is completed.
- the driver Since the predetermined delay time D 12 from the arrival of the first gear to the second gear is instructed according to the starting water temperature TWI NT (starting state), the driver displays As long as the shift from the 1st gear to the 2nd gear is performed according to the instruction of the first indicator lamp 53a (shift up time indicating means), the difference in the starting water temperature TWI NT Therefore, the early activity of the horn butterfly 9 can be surely performed.
- the time until the shift up command from the 1st gear to the 2nd gear is commanded may be in the vicinity of the upshift vehicle speed VSP 1 2 (15 Km / h) set after the engine warm-up is completed, for example 16 KmZ h But that's right.
- the other upshifts are fixed, but the upshift vehicle speed and the delay time may be set in accordance with the engine start state as in the upshift from the first speed to the second speed.
- the shift-up vehicle speed VSP 1 2 from the first speed to the second speed and the predetermined delay time D 1 2 are returned to the values after the completion of the engine warm-up.
- FIG. 5 is a second embodiment, which replaces FIG. 3 of the first embodiment.
- the flowchart of the second embodiment is not shown, it is the same as FIG. However, the method of instructing the shift-up time is different from the first embodiment. That is, in the second embodiment, when the delay time D 1 2 from when the shift up condition from the 1st speed to the 2nd speed is established until the shift up time from the 1st speed to the 2nd speed is instructed, 1 1 Fig. 5 shows the delay time D 1 2 until the shift up timing instruction from the 1st speed to the 2nd speed is provided, when there is a shift up timing instruction means to indicate that it is time to shift up from the 2nd speed to the 2nd speed. As shown, it is set according to the starting water temperature TW INT (starting state). From Fig.
- the lower the start-up water temperature TW INT the longer the delay time D 1 2 from when the upshift condition is satisfied until the upshift from 1st to 2nd.
- the delay time D 1 2 from when the shift up condition is satisfied until shifting up from the 1st gear to the 2nd gear is lengthened according to the start-up water temperature TWINT.
- the lower the start-up water temperature TW INT the longer the time until activation of the catalyst 9 becomes.
- FIG. 6 shows a modification of the display device 53, which can be applied to both of the previous two embodiments.
- the display device 53 includes an indicator lamp 54 and a time display window 55.
- Display device 5 3 indicator light 5 4 is one, shift up time from 1st gear to 2nd gear, shift up time from 2nd gear to 3rd gear, shift up time from 3rd gear to 4th gear 4
- This indicator light 5 4 lights up at the time of shifting up from 5th to 5th to instruct the driver to shift up.
- the time display window 5 5 is used when the catalyst 9 is inactive, and displays the delay time D 1 2 set at the start. When the water temperature at start-up TW I NT is low, the number displayed in the time display window 5 5 increases, so the driver can easily understand that the indicator light 5 4 lights up slowly, and the indication It becomes easy to follow.
- D 12-T (that is, the remaining time of the delay time D 12) may be displayed while the timer T is counting up. If such a display is made, the remaining time until the upshifting time (indicator light 5 4 lights up) when the driver sees the display device 5 3 because it feels uncomfortable that the indicator light 5 4 does not light easily. It can be communicated, and the shift-up operation at an appropriate timing can be further assisted.
- FIG. 7 is a flowchart of the third embodiment for controlling a monitor (display device). This flow is executed at regular intervals (for example, every 10 O msec). As in the first embodiment above, the vehicle speed is increased from 1st speed to 2nd speed for the early activation of catalyst 9 before the engine warm-up is completed.VSP 1 2 and delay time D 1 2 are After completion When this is done, for the driver, before the engine warms up, the first indicator light 5 3 a is lit later than after the engine is turned off, so it is time to shift from 1st to 2nd. There is still some possibility of feeling late.
- the third embodiment is premised on either the first or second embodiment, and a monitor capable of displaying a message (message) in the driver's seat is provided, and the first indicator light 5 3 a (shift time) Determine whether or not the shift from 1st gear to 2nd gear has been performed as instructed by the instruction means), and based on this determination result, shift up from 1st gear to 2nd gear as instructed by the first indicator light 5 3a
- the vehicle is on, drive the message that means that, and as indicated by the 1st indicator light 5 3 a, drive the message that means that when the shift from 1st to 2nd is not performed
- the shift-up time indicator device 53 and the monitor should be placed adjacent to each other so that the state of the first indicator light 53a and the message can be seen simultaneously (without moving the line of sight).
- step 2 1 the catalyst sensor 3 Compare the catalyst temperature TCAT detected by 7 with the specified catalyst activation temperature TO. When the catalyst temperature TCAT is less than the catalyst activation temperature TO (catalyst inactive state), proceed to step 22 to check whether the first indicator lamp 5 3 a of the upshift timing indicator is off. When the first indicator light 5 3 a is off, the engine controller 3 1 has instructed the driver to wait until the shift up timing from the first gear to the second gear in order to activate the catalyst 9 early. Judge and go to Step 2 3 to compare the actual gear position with the 1st gear.
- the actual gear position is detected by providing a switch similar to the inhibitor switch provided in the automatic transmission.
- the actual gear position may be estimated from the ratio between the actual vehicle speed VSP and the engine speed N e. If the actual gear position is in the 1st gear, the driver determines that it is waiting for the shift-up time from the 1st gear to the 2nd gear according to the instructions of the 1st indicator light 5 3 a, and the driver's seat is monitored in step 2 4 The message “Catalyst warming up” is displayed in text and the current process is terminated.
- the message “Catalyst is warming up” is a message that means when you are waiting at the 1st speed until the shift up time from the 1st speed to the 2nd speed as indicated by the 1st indicator light 5 3 a It is. Looking at this “catalyst warming up” message, the driver understands why he must wait until the shift up to the 2nd gear while maintaining the 1st gear, so the shift up from the 1st gear to the 2nd gear There is no psychological resistance to waiting.
- step 26 After confirming that the actual gear position is not in the R (reverse) position in step 5, in step 26, display the message “Environmental deterioration” on the driver's seat in text and end the current process. To do.
- This "environmental deterioration" message means that when you are not waiting for 1st gear until the upshifting from 1st gear to 2nd gear as instructed by 1st indicator light 5 3a.
- step 2 1, 2 2, 2 3 to step 2 4 and the message “Catalyst warming up” will be displayed in text on the driver's seat monitor. If the actual gear position is in the R position, proceed from step 25 to step 27 and display nothing on the driver's seat monitor. If the catalyst 9 is inactive in steps 2 1 and 2 2 and the first indicator light 5 3 a is lit, it is determined that such a situation cannot occur, and the process proceeds from step 2 2 to step 2 7. Nothing is displayed on the driver's seat monitor.
- steps 2 1, 2 8, 2 9, 3 1, 3 4, 3 5 are portions for determining whether or not the gear is shifted up as instructed by the first indicator light 5 3 a.
- the process proceeds from step 21 to step 28 and looks at the first indicator light 5 3a.
- the first indicator light 5 3 a is lit, the early activation of the catalyst 9 is completed and it is time to shift up from the first gear to the second gear, that is, the driver shifts from the first gear to the second gear.
- Judge that it is instructing up, and in step 29, compare the actual gear position with the 2nd speed.
- the driver determines that the gear has been shifted up from the 1st gear to the 2nd gear according to the instructions in the 1st indicator light 5 3 a.
- the message “Good” is displayed in text and the current process is terminated. This “good fuel consumption” message means that when shifting from 1st gear to 2nd gear as instructed by the 1st indicator light 5 3 a, it means that.
- this “environmental deterioration” message is a message that reminds you when the gear has not been shifted up from 1st gear to 2nd gear as instructed by the 1st indicator light 53a.
- step 2 1 , 2 8, 2 9 and step 3 0 The message “Good fuel consumption” is displayed in text on the driver's seat monitor. If the actual gear position is in the R position, proceed from step 31 to step 33 and display nothing on the driver's seat monitor. If the first indicator light 5 3 a is turned off in step 2 8, go to steps 3 4 and 3 5 to see if the 1st speed is selected as in steps 5 and 6 in Fig. 2. If 1st gear is selected, go to Step 3 6 to monitor the driver's seat
- Step 21 it was determined whether or not the catalyst 9 is in an inactive state based on the catalyst temperature TCAT. However, the catalyst 9 is not based on the starting water temperature TW INT that can be detected by the water temperature sensor 35. It may be possible to determine whether or not it is active. For example, when the starting water temperature TWINT is a predetermined value (for example, 50 ° C.) or less, the catalyst 9 is determined to be in an inactive state. Note that the predetermined value is not limited to 50 ° C, but is set according to compliance. In steps 2 and 4 above
- ⁇ 6> Instead of displaying “Good fuel consumption”, this is communicated to the driver by voice or by voice.
- the message indicating "good fuel consumption” means that the first indicator
- the message “environmental deterioration”, which is the meaning of the message is instructed to the driver's seat monitor (display device) (Steps 2 1 and 2 8 in FIG. 7). 2 9, 3 0 and steps 2 1, 2 8, 3 4, 3 5, 3 6 and steps 2 1, 2 8, 2 9, 3 1, 3 2) It is possible to reduce the uncomfortable feeling of driving due to the difference in the shift-up vehicle speed VSP 1 2 from the 1st speed to the 2nd speed after completion and the predetermined delay time D 1 2.
- the third embodiment it is possible to make the driver aware of it, so that the vehicle shifts as instructed by the first indicator light 53a (shift-up time indicating means). Increased chance of being uploaded.
- the first indicator light 5 3 a By displaying on the driver's seat monitor that the fuel economy is advantageous in step 30 of FIG. 7, if the driver emphasizes fuel efficiency, the first indicator light 5 3 a ( It is expected that the gear will be shifted up as instructed by the shift up time instruction means).
- the first indicator light 5 3 a can be used by drivers who look at maintenance by displaying the bad environment on the driver's seat monitor in step 3 2 of Fig. 7. It is expected to shift up as instructed by (shift-up time instruction means). JP2005 / 024020
- the driver will not follow the instruction of the 1st indicator light 5 3a (shift up time indicating means), and it will be time to shift up from 1st speed to 2nd speed. If the speed is shifted up from the first speed to the second speed before, the engine speed N e decreases and the exhaust temperature decreases, resulting in insufficient early activation of the catalyst 9.
- the 1st speed is changed from the 1st speed to the 2nd speed as instructed by the first indicator light 5 3 a (shift completion time indicating means).
- the first indicator light 5 3 a (shift-up) It is expected to shift up as instructed by the timing instruction means.
- the first indicator light 5 3 a (shift It is expected to shift up as instructed by the up-time instruction means.
- shift-up times shift-up times from 2nd to 3rd, 3rd to 4th, 4th to 5th
- the transmission that performs the shift by the driver's shift operation is provided.
- the equipped vehicle can improve fuel efficiency and activate the catalyst early.
- the present invention brings about a preferable effect when applied to a vehicle equipped with a transmission equipped with a manual mode in which a gear shift is performed in accordance with a driver's instruction even in the case of a manual transmission or an automatic transmission.
