Description

200905107 IX. Description of the Invention: [Technical Field] The present invention relates to a control device for a straddle type vehicle, a transmission, and a straddle type vehicle. [Prior Art]

An electronically controlled transmission (hereinafter referred to as "r ECVT" (electronically controlled continuous variable transmission)) having a gear ratio that can be controlled in a continuously variable manner is known. The 'speed ratio ratio base ratio shift ratio map is automatically changed in the ECVT, and the speed ratio map indicates the relationship between the speed ratio and a vehicle running state (e.g., vehicle speed, engine speed, and throttle opening degree). Accordingly, in a vehicle equipped with an ECVT (hereinafter referred to as "ECVT equipped vehicle"), a driver does not have to perform a shifting operation or a clutch operation. Since then, Ecvt has been installed in all types of vehicles. However, in the ECVT equipped vehicle, the μ cannot arbitrarily change the gear ratio to a gear ratio other than the gear ratio automatically determined in the gear ratio map. In other words, the speed ratio cannot be arbitrarily changed except for the setting of the speed ratio map. Therefore, the driver of the ECVT equipped vehicle is quite troublesome based on his intention to actively use the engine to brake the car. More specifically, it is quite troublesome for the driver to actively use an engine that is stronger than the one set by the gear ratio map. In addition, for example, in an ECVT-equipped vehicle, when the driver wishes to overtake another handle, the driver intentionally over-converts to increase the vehicle acceleration (i.e., the execution-downshift acceleration operation) is also quite sleepy. In view of the above situation, an ECVT equipped vehicle has been proposed which allows selection of an 129876.doc 200905107 alternative AT mode or an MT mode in which the octet mode is continuously changed, and in the MT mode, the shift speed is automatically - Operate to change. More specifically, for example, among the drivers, an ECVT equipped vehicle is proposed, in which the patented document 1 position can be used to manually set the gear ratio reduction cup of the continuously variable transmission - in Patent Document 2, In addition and 'for example, the CVT is equipped with a vehicle face, which is provided with a switch for forcibly changing the gear ratio or manually performing a downshift. - for

[Advantages of the Invention] 129876.doc 200905107 According to the present invention, it is possible to easily perform downshifting and adjust the number of downscalings [Embodiment] «First Embodiment" <<Structure of Motorcycle 1> In the example, an example of an embodiment of the present invention will be explained with reference to a motorcycle 1, which is a motorcycle-pedal model motorcycle. .3, for example: The motorcycle 1 includes a handle 4, a power unit 2, and a rear wheel as a drive wheel. The power unit 2 and the rear wheel 3 are connected by a force transmission mechanism 6. (Handle 4) Figure 2 shows the outline of the overall structure of the handle 4. The handle 4 is provided with a handle ^, 4d which is coupled to a steering head tube (not shown). The handle 4 is provided with a left grip (10) and a right grip, the left grip is positioned at the left end area & and the 5th right grip is positioned at the right end of the handle strip . = grip servant formed - throttle operation (four). What is the right grip relative to the handle 〇 (3) (four).

In the switch box off 42 I various operating switches 'which include - upshift switch 41, - downshift open and lower limit allowable switch 43 and - mode selection switch 44. Various operation switch hearts are placed at the position of the allowable - left hand 60 - thumb advancement - 'including upshift switch 41, downshift switch 42, phase drop enable switch 43 and mode The selection switch 44' is shown in Fig. 3. More specifically, each type of operation opening relationship is set in the upper surface of the opening which is slightly downward and inclined backward. In other words, each type of operation opening relationship is set on the side facing the driver. On the surface of the switch box 40. However, the present invention is not limited to this configuration. For example, an upshift switch == an operation switch can be provided to the switch box 4. One of the rear surface sides (from the driver-Shaw) The switches are operated by the index finger. For example, 42 may be provided on the surface of the driver's side, and the upshift switch 41 is set on one of the surfaces of the driver's angle. In other words, the switch 42 can be operated by the thumb _ while the upshift switch is operated by the index finger. In addition, all of the operating switches can be placed to the rear side of the switch box 4〇 (from the driver's perspective of 129876.doc 200905107) so that the operating switches can be operated by the index finger. It should be noted that the positional positioning of the downshift permit switch 43 and the mode selection switch 44 is not limited to the left grip 4a. For example, the descending power allowing switch and the mode selector switch can be disposed at the left side of the right grip 4b. More specific ancient 2' may be provided at the left section of the right grip 4b - an additional switch box, at least one of the shift permit switch 43 and the mode select switch 44 may be disposed within the front switch. In this case, the switch provided in the additional switch box is advantageously disposed at a position where the thumb of the right hand of the driver can operate or at a position where the index finger of the right hand of the driver can operate. Moreover, for example, the downshift permit switch 43 and the mode selection switch material may be disposed on the switch case 4A provided on the left grip 43, and the other of the downshift permit switch 43 and the mode selection switch 44 may be Set on the switch box provided on the right grip. In this particular embodiment, various types of operational switches, such as lift switch 41, downshift switch 42, downshift enable switch 43, and mode select switch 44, are push button switches that are pressed. However, each of the various types of operation switches may be a push-pull lever. Alternatively, each of the various types of operational switches may be a rotary switch that has a knob that is movable between a plurality of positions. Referring to Fig. 3', among the various types of operation switches, the lift switch ^, the downshift switch 42, and the downshift permit switch 43 are disposed closest to the driver's left hand (9). In other words, the 'upgrade switch 41, the downshift switch 42, and the downshift: the switch 43 are further outwardly disposed in the vehicle width direction. The downshift permit switch u is disposed between the upshift switch 41 and the drop switch 42. Mode selection switch 44 129876.doc -14- 200905107 : Set at a position other than the upshift switch 41, the down (four) off 42 and the downshift permit switch 43 further away from the left hand 6 。. This is because the frequency of use of the mode selection switch 44 is lower than the frequency of use of the upshift switch 41, the downshift switch 42, and the downshift enable switch 43. In this manner, the more advantageous system, the upshift switch 41 having a relatively high frequency of use, the downshift switch 42, and the downshift permit switch 43 are disposed to the left hand 6G of the 相田谷易. However, the present invention is not particularly limited to this configuration. ,

Ο (Power unit 2) As shown in Fig. 4, an engine 10 serving as a drive source, an electronically controlled transmission 2G, a centrifugal, a clutch 3G, and a reduction mechanism 31 are provided. The transmission 2 is equipped with a transmission gear mechanism 21 and a motor 22 which serves as an actuator: the motor 22 changes the gear ratio of the transmission gear mechanism 21. The transmission gear mechanism 21 includes a main sheave 23 and a pair of sheaves 24. The main sheave 23 is provided on the output shaft 12 of the engine 10 and wraps around the rotation of the output shaft 12. A belt 25 having a V-shaped cross section is wound around the main sheave 23 and the auxiliary sheave 24. The motor 22 is attached to the main sheave 23 . The width of the belt groove of one of the main sheaves 23 around which the belt 25 is wound is modified by the motor 22, whereby the speed ratio of the shifting gear mechanism 21 can be continuously changed. More specific. The gear ratio of the shift gear mechanism 21 can be changed without stepping. The auxiliary sheave 24 is connected to the speed reduction mechanism 3 through the centrifugal clutch 3〇. Further, the speed reduction mechanism 31 is coupled to the rear wheel 3 via a force transmission mechanism 6 such as a belt, a chain or a drive shaft. The centrifugal clutch 30 is engaged and disengaged according to the rotational speed of the auxiliary sheave 24 and is clearer when the rotational speed of the secondary sheave 24 is less than a predetermined rotational speed of 129876.doc •15-200905107. Riding off. Accordingly, the rotation of the sub-groove (4) is not transmitted to the rear wheel 3. On the other hand, if the rotation speed of the auxiliary sheave 24 is equal to or greater than the determined rotation speed, the centrifugal clutch 4, the rotation of the auxiliary sheave 24 is transmitted to the force transmission mechanism 6 via the centrifugal clutch 3〇 and the speed reduction mechanism. Rear wheel 3. Thereby, the rear wheel 3 will rotate. "Control Section of Motorcycle 1"

- Next, the control block of the motorcycle i will be explained with reference to FIG. The control of the motorcycle 1 is mainly performed by a foot (electronic control unit) 5 serving as a control device. Qing 5 has: a memory, which memorizes various setting types, etc.; - CPU (Central Processing Unit) 50, which serves as a computing unit; and a driving circuit 56. The CPU 5 has a downshifting operation amount calculating portion... - a groove change mode selection portion 52, a cancel money output portion 53, a downshift cancel portion 54 and a gear ratio control portion. Various sensors and switches are connected to the ECU 5. More specifically, the downshift allows The switch 43, the mode selection switch 44, the upshift switch 41, the downshift switch 42, the throttle opening degree sensor 33, the brake lever, the engine speed sensor 11, the sheave position detecting sensor 26, and the The auxiliary sheave rotation speed sensor 27, the throttle operating member sensing (10) and a vehicle speed sensor (2) are connected to the ECU 5. When operated by the driver, the downshift permitting switch 43 outputs the downshift permitting signal 101 to ECU 5. When the taxi is made by the driver, the mode selection switch 44 outputs the mode, and the model k selects the number 102 to the ECU 5. The throttle opening degree sensor, 33 the beta motorcycle 1 "& door opening degree. Throttle opening degree sensor 33 Connected to throttle 7G. Throttle opening degree sensor (10) is _ throttle opening degree 129876.doc -16- 200905107 Signal 103 is out of the way: Sight π detects the throttle opening degree to Ecu, the brake lever slams Tian Yuwu driver outputs a brake signal 104 to Ecu 5. :: During the operation of the driver's operation of the brake lever Μ to the driver releasing the brake lever 4c, the brake lever 4e will continue to output the brake signal m. The upshift switch 41 outputs an upshift signal WCU5. When the driver is operating, the & shift switch 42 outputs a downshift signal 1〇6 to 11U 5 〇Γ u The engine speed sensor U detects the engine 1 The rotational speed of the sensor Η as the engine speed signal (10) outputs the rotational speed of the engine 1G to the ECU 5. The sheave position ❹ 测 26 26 _ the gear ratio of the transmission gear mechanism 21, the sense, the device t specific The sheave position detecting sensor 26 detects the width of the belt groove of the main sheave 23. For example, in this embodiment, the main sheave 23 has a structure including a fixed sheave body And -: moving the sheave body 'the movable sheave body has a relative to In the case of fixing the position of the sheave body relative to the displacement, the sheave position detecting sensor 26 measures the position of the movable sheave body relative to the fixed sheave body. In addition, the sheave position detecting sensor 26 as a position of the 110 output material chute wheel to the Qing 5. The auxiliary sheave rotation speed sensor 27 detects the rotation speed of the auxiliary sheave 24. The auxiliary sheave rotation speed sensor 27 serves as a pair of sheaves The rotation speed signal m outputs the detected rotation speed of the field 4 wheel 24 to the ecu 5. The vehicle speed sensor 32 detects the vehicle speed of the motorcycle 1. The vehicle speed sensor 32 outputs the detected vehicle speed to Ecu 5. It should be noted that the vehicle speed 129876.doc 200905107 degree sensor 32 may be a sensor that detects the rotational speed of the rear wheel 3. However, for example, the vehicle speed sensor 32 may be a sensor that obtains the speed of the vehicle by detecting the rotational speed of one of the output shafts of the speed reduction mechanism 31. The vehicle speed sensor 32 may be a sensor that obtains the speed of the vehicle by detecting the rotational speed of the front wheels. (Overview of Control of ECU 5) The ECU 5 controls the engine 1 更 More specifically, the Ecu 5 calculates an engine speed serving as a target based on the throttle opening degree signal 103, the vehicle speed signal 112, and the like. The ECU 5 adjusts one ignition timing of an ignition device (not shown) of the engine 10, a fuel supply amount supplied to the engine 丨0, and the like, while monitoring the engine speed signal 109, thereby controlling the rotation speed of the engine 等, etc. To the calculated target engine speed. Further, the ECU 5 also controls the transmission 2〇. More specifically, the ECU 5 calculates a gear ratio serving as a target from the engine speed signal 1 〇 9, the vehicle speed signal 丨丨 2, and the like. Further, the ECU 5 detects the current gear ratio of the transmission 20 based on the sheave position signal 11 or the like. Further, the ECU 5 outputs a pWM (pulse width modulation) signal to the drive circuit 56 based on the calculated target speed ratio and the detected current speed ratio. The drive circuit 56 applies a pulse voltage in accordance with the input pWM signal to the motor 22. According to this, the speed ratio of the transmission 2〇 is controlled to the target speed ratio. It should be noted that in this embodiment, an exemplary explanation is provided in which the PWM control motor 22 functions as an actuator that changes the gear ratio of the shift gear mechanism 21. However, the type of actuator used to change the speed ratio of the transmission 2〇 in the present invention is not particularly limited. For example, changing the gear ratio of the transmission 2〇 129876.doc < 18- 200905107 may be a -PAM (Pulse Amplitude Modulation) control motor. Further, the actuator of the speed ratio of the transmission 20 may be a stepping motor. Alternatively, the actuator of the variable speed changer 20 may be a hydraulic actuator or the like. Next, the control of the gear ratio of the transmission 2〇 will be explained in more detail, and the selection of the shift pattern will be explained with reference to Fig. 5 and the like. (Shift mode selection) On the motorcycle! Medium 'may choose - ΑΤ mode, one manual machi mode, one automatic ΜΤ mode. As shown in FIG. 4 and FIG. 5, the driver mode selection switch 44 can be selected to select the ΑΤ mode, the manual ΜΤ mode, and the automatic Μ 模式 mode: Referring to FIG. 4 ′ when the driver operates the mode selection switch material, the mode selection switch 44 is selected. The mode selection signal (10) is output to the syllabary 5. More specific: 2, the mode selection signal 102 is output to the shift mode selection in the ECU 5; the minute ~ when the mode selection signal (10) is input to the shift mode selection part a ' as shown in Figure 5, will shift from the current Mode switches the shift mode. For example, if the current changeover mode is like the T mode, if the driver operates the mode selection switch 44-times, it will switch to the automatic town mode. If the driver then selects switch 44 again, then it will switch from automatic mt mode to 44, then? Manual: Also, the right driver operates the mode selection switch again. The camera will switch to the initial eight-but mode. In other words, the secondary operation mode selection switch 4 continuously switches the switching mode. When the shift mode is changed in this manner by the selection signal 1〇2', the speed change boring tool 55 controls the shift of the shift (10) according to the changed shift pattern, in this embodiment. , is an explanation - an example, in which each time 129876.doc -19- 200905107 operates the mode selection switch 44, the combined ds continues to change the shift mode. However, for example, a mode selection switch for selecting the Ατ mode, a mode selection switch for selecting the automatic MT mode with = and a mode selection switch for selecting the manual mode may be separately provided. "AT mode" ▲ "AT mode" is a mode in which the speed ratio control portion 55 continuously and automatically changes the speed ratio of the transmission 2 according to the traveling state of the motorcycle. In other words, the "AT mode" is a mode in which the speed ratio of the transmission 20 is continuously changed without stepping in accordance with the traveling state of the motorcycle i. The "A-butyl mode" may be, for example, a mode in which the gear ratio control portion 55 continuously and automatically changes the gear ratio of the transmission 2 based on a predetermined gear ratio map. The 6-inch gear ratio map is stored in the memory 57 in the ECU 5, and defines the relationship between the running state of the motorcycle 1 (e.g., vehicle speed 'engine speed and throttle opening degree, etc.) and the gear ratio. The gear ratio control portion 55 shown in Fig. 4 calculates a target gear ratio based on the gear ratio map, the vehicle speed signal 、, the engine speed number 109, and the like. The speed ratio control portion $$ outputs a PWM signal 108 to the drive circuit 56 based on the calculated target speed ratio, the sheave position signal 丨丨〇, and the sub-groove rotation speed number 111. The drive circuit 56 applies a pulse voltage to the motor 22 at the PWM signal 1〇8. Thereby, the drive motor 22' thereby adjusts the width of the belt groove of the main sheave 23. According to this, the speed ratio of the transmission 20 is changed until the target speed ratio is reached. "MT mode" On the other hand, the "MT mode" is a mode in which the speed ratio of the transmission 20 is automatically or manually changed between a plurality of predetermined speed ratios. In the case of "model 129876.doc -20- 200905107 hi Bu, the driver operates pa y ........ - V 丌 switch 41 and downshift;: the mode of changing the speed ratio of the transmission 20 "Manually in the "manual ΜΤ mode", the driver is responsible for it... It should be noted that the "ΜΤ mode" is sometimes called a mode to distinguish it from the mode under the normal manual transmission, in the mode = The gear ratio is physically changed between a plurality of gears. 2, "Manual ΜΤ mode" More specifically, in this embodiment, as shown in Figure 6, a nearly fixed gear ratio, that is, from the L 〇 w side, - first speed, speed two - third Speed, a fourth speed, - fifth speed:. It should be noted that '...the speed ratios of the first to the fifth speeds may be completely fixed or may vary, for example, depending on the engine speed. More specifically, for example, as the engine speed becomes higher, the gear ratios of the gear ratios (i.e., the _th speed to the fifth speed) may be set closer to the top side. In the manual mode, the speed ratio is not substantially changed as long as the driver does not operate the operation switch such as the up switch. In other words, = ΜΤ under ’ as long as the driver does not operate the operation switch such as the upshift switch w or the downshift switch 42, the gear ratio of the transmission 2 基本上 does not substantially change automatically between the respective speed ratios. However, for example, when it is possible to perform a kickdown to, for example, prohibit the engine from turning off when the speed of the motorcycle 1 is lowered, etc., there are exceptions. For example, in order to explain the case shown in the example of Fig. 6, when the motorcycle starts to travel at the first speed, until the upshift switch 4 is operated, the speed ratio of the transmission remains at the first speed. At the point eight, when the driver operates 129876.doc 200905107 as the lift switch 41, as shown in Fig. 4, the upshift signal (10) is output from the lift switch 41 to the ECU 5. When the upshift signal 1〇5 to £〇1; 5 is entered, the gear ratio control portion 55 in 5 outputs the P WM signal! 〇8 to the drive circuit 56 to change the speed ratio of the transmission 20 from the first speed to the second speed. The drive circuit 56 applies a pulse voltage to the motor 22 in accordance with the PWM signal 1〇8. Thus, as seen from Fig. 6, the speed ratio of the transmission 2 is switched to the second speed. Similarly, at point B, when the upshift switch 41 is operated again, the speed ratio of the transmission is switched to the third speed. Aspects For example, at point C in FIG. 6, when the downshift switch 42 is operated, as shown in FIG. 4, the downshift signal 1〇6 is output from the downshift switch 42 to the ecu 5. When the downshift signal 106 is input to the ECU 5, the speed ratio control portion 55 in the ECU 5 outputs the PWM signal 1G8 to the drive circuit % to change the speed ratio of the transmission 2 from the fifth speed to the fourth speed. The drive circuit % applies a pulse voltage to the motor in accordance with the PWM signal 108. . Thus, as shown in Fig. 4, the gear ratio of the transmission 2G is switched from the fifth speed to the fourth speed. "Automatic MT mode" In the MT mode, the gear ratio control portion 55 automatically changes the gear ratio of the transmission 2〇 between a predetermined plurality of gear ratios without depending on the mode of operation of the driver. mode". Referring to the example shown in Fig. 7, when the automatic MT mode is called by the shift mode selection portion, the speed ratio of the transmission 2 is automatically changed in accordance with the change in the traveling state of the motorcycle. However, in the case of the automatic MT mode, unlike in the AT mode, the gear ratio is discontinuously changed. In other words, in the case of the automatic mode, the speed ratio is not like that in the τ mode, there is no step change 129876.doc -22- 200905107. In other words, in the automatic Μτ mode, automatically between these preset speed ratios. Change the gear ratio of the transmission 2〇. It should be noted that in the automatic MT mode, the timing of the shift is set differently depending on, for example, the degree of throttle opening. More specifically, when the driver is upshifted, when the driver When the throttle 70 has been opened to a greater extent to accelerate relatively quickly (in other words, when the throttle opening degree is large), the change of the sand will be performed at a relatively high engine speed. On the other hand, when the driver has Turning on the throttle 7〇0 ^杈 small private degree to accelerate quite slowly (in other words, when the throttle opening granularity is #乂小日^), the conversion will be performed at a fairly low engine speed. At the time of downshifting, the timing of the shift is set to be different depending on, for example, the degree of throttle opening. (Downshift Allow Mode) "Overview of Downshift Allow Mode" As shown in Figure 5, in this particular embodiment 'may be from AT Mode, automatic mode ^ and manual MT mode shift to - downshift allow mode. Here, the ◎ lowering § permission mode is based on the operation of the throttle operating member 71 to allow a shifting mode in which the downshift is performed in accordance with the operating state of the door operating port 172. In the case of Lu, the "downshift permission mode" allows one of the downshifts to be a downshift #-shift mode, which is reflected in the driver's attempt to change the gear ratio of the gear mechanism 21 by the downshift. Proactive use of the downswing or the driver's intention when the engine is braking. "Downdown allows AT mode" Q0 - τ " _, L, in this embodiment, it is possible to switch from AT mode to a downshift to allow AT mode. Here, the "downshift allowable Ατ mode" is in the 129876.doc • 23· 200905107 drop-off permit mode--leak-type, which continuously and automatically changes the shift after performing the downshift according to the operating state of the throttle operating member η 21 speed ratio. Ah, as can be seen from Fig. 8, at step 81, when the driver operates the downshift permit switch 43, the drop k permission number 1G1 is output from the helium allowable switch 43 to 5' as shown in Fig. 4. More specifically, the downshift allows the signal to be rotated to Γ

J shift mode selection portion 52. When the downshift permitting signal 1G1 is input to the groove changing mode selecting portion 52, the (four) mode selecting portion 52 is allowed to (4) from the descending groove. In other words, when the player downshift allows the letter to change the board selection portion 52, the downshift is allowed to allow the pitch instead of the Μ mode. It should be noted that even after the change to the allowable Ατ mode to the operation of the throttle operating member 71, the normal change of the gear ratio for controlling the transmission gear mechanism 21 under normal boring is performed; the transmission gear mechanism 21 The speed ratio. The watch comes & then, as shown in Fig. 8, at step 82, it is determined whether or not the operation unit 71 has been operated. More on the day of the selection of bamboo...

In general, the "casting operation amount" is a number of downshifts that are expected by the driver and can be estimated from the state of the vehicle of the motorcycle i. Here, the "downshift number" is the number of changes to the low side of the speed ratio of the transmission gear mechanism 2ί. More specifically, in this embodiment, the downshift operation amount is calculated using a downshift operation amount map stored in the memory 57. Here, the downshift, the amount of the map shows the vehicle status and the downcast operation amount of the motorcycle Ο ~ Μ ,, idea, here, will be about a case = release example 'in this case' The downshift operation amount map indicates a mapping table of the downshift operation ϊ and the operation speed of the throttle operating member 71, and the relationship between the motorcycle and the vehicle speed/door operating member 71.

For example, the downshift operation amount map may be a map of the relationship between the display operation amount and only the <RTIgt; Further, for example, the downshift is not a dull, and the table may display a downshift operation amount and a map of a function which divides the throttle operating member 7 into a second operation unit as a variable.

',, the table should be noted 'This configuration can make the shift operation amount constant relative to the degree or not constant with respect to the vehicle speed. In other words, the amount may be a function of the speed of the vehicle. :Different chastity: When the driving state of the car 1 is the same, the gear operation: Can:: The 变得 becomes larger as the vehicle speed increases. Further, in the case where the motorcycles are in the same state, the downshift operation amount may be set to increase in speed and become smaller. Vehicle Next, after step S3-1, step S3_2 is performed. In step illusion = the amount of downshift operation calculated at step (1) to perform the gear shifting of the gear ratio. More specifically, the calculation of the falling operation amount = output the calculated downshift operation amount to the speed ratio control, for example, the speed ratio ratio "knife 55 shifts the gear ratio of the gear mechanism 21 to the green cut ground." Doc -26- 200905107 Operational volume. Thereafter, as shown in Fig. 8, the shift is shifted to a downshift correction AT mode. Heart/mind thinking, under the downshift correction A, a ^ ^, the more advantageous is to set the engine speed to the upper limit so that the engine will not overturn. The speed of the engine should be noted at 'at step 32, in the case, at the step, no; the speed ratio of the throttle operation unit (4) has been operated 疋 疋 疋 疋 疋 降 降 降 降 降 降'At step S2, even if it is determined that the operation has been made, by the threshold member 71, if the throttle #^. , & is also known as the throttle 7 and the operation amount of the throttle 70 is small, then in the step S3_; (where) the amount of sandaling operation is zero. For the ancient M, the fourth part will be calculated. For example, if the throttle 7〇 operation amount is equal to or less than a predetermined operation, the temple is at or less than one. And the operating speed of the throttle 70 is equal to eight 51^, then in the step of the team 1, the reduction of the operation amount of the calculation of the boring tool 5 1 曰 juice countdown operation, the driver of the yin active to replace / zero. Because the probability is better in this situation; 1 is used by the downswing to speed up the acceleration or the engine is also in the unfavorable situation, for example, in the case of the expected downshift, the motorcycle i will In the case of the operation and quantity calculation section 51, 1 1% 'is then stepped at step S3_1. In the middle of the gear; the amount is zero. In other words, the vehicle state of the motor vehicle used in the 1 ^ * downsizing operation includes the difference between the vehicle speed sensor and the speed sensor by the loose speed measurement. The operation amount and the operation speed of the speed component 71 such as the motorcycle 1 acceleration and the slip state, and the vehicle speed and the speed of the vehicle are executed in steps S3-3. 3 places 'by ECU 5 ruling 0 end a 丄, 疋 No has performed a predetermined operation on motorcycle 1 and 129876.doc -27- 200905107 Whether to meet the motorcycle!

The routine proceeds to the step. Next, at step S4, 'output from the cancel signal output portion 53 - cancel the letter' to the down-slot cancel portion 54. Cancel the reduction of the floor correction at mode °, the speed change gear, the control of the gear ratio of 21 Returning to the shifting based on the shifting gear, which is used to control the shifting gear mechanism 2 in the normal AT mode, in step S3 & W, in other words, as shown in Fig. 5, at the step, from the downshift right The AT mode returns to the downshift enable AT mode. It should be noted that in this case, continuing the downshift as it is is allowed to allow the AT mode without returning to the AT mode. In other words, when the downshift allows the Ατ mode, when operating the throttle operating part At 71 o'clock, this action causes the shift to the downshift correction AT mode. Thereafter, if it is decided to perform the predetermined operation on the motorcycle 1 or to satisfy the predetermined condition of the motorcycle 1, the return from the downshift correction AT mode to the Downshifting allows AT mode. If it is determined in step S2 that the accelerator operation unit has not been operated, the routine proceeds to step S4. More specifically, if the throttle operation unit 71 has not been operated at the step, the shift to the production correction AT mode is not performed. Then, the control of the speed ratio of the transmission gear mechanism 21 continues based on the normal AT mode. The normal speed ratio map of the speed ratio of the speed change gear mechanism 21 is controlled. Next, after step 84, step S5 is performed. At step S5, it is decided 129876.doc -28- 200905107 whether the mode selection switch 44 has been operated and whether the core selection signal 102 has been output from the mode selection switch 44 to the ECU 5. If it is determined at step S5 that the pull select signal 102 to Ecu 5 has been output, as shown in Figs. 5 and 8, the AT mode is allowed to return to the at mode from the downshift. On the other hand, if it is executed in step S5. If the mode selection signal 102 has not been turned to the ECU 5, then returning to step S2 ° should be considered, in this particular embodiment, an example is explained, wherein the setting system When the mode selection signal 102 is output to the ECU 5, the downshift allows the AT mode to return to the Ατ mode. However, the invention is not limited to this setting. For example, the setting may cause the down mode to be returned from the down mode to the AT mode when the downshift enable signal 101 is output to the ECU 5 in the downshift permitting AT mode. Alternatively, the setting may cause the AT mode to return to the AT mode from the downshift when the upshift signal 1〇5 or the downshift signal 106 is output to the ECU 5. - Downshift Correction AT Mode - 〇 Next, the downshift correction eight-but mode will be explained in more detail with reference to FIG. In the downshift correction AT mode of this embodiment, instead of calculating the gear ratio calculated by the gear ratio of the gear ratio of the transmission gear mechanism 21 in the normal AT mode, the gear ratio is constantly controlled. To exactly the 'shift ratio' of the downshift operation amount calculated at step S3_1. In other words, in the downshift correction eight-but mode of this embodiment, the gear ratio is calculated using a new gear ratio map, which is used to calculate the shift gear mechanism in the normal AT mode. The gear ratio of the gear ratio of 21 is obtained by exactly shifting the downshift operation amount to the L〇w side. Next, 129876.doc -29- 200905107 controls the shifting ratio of the shifting gear mechanism 2, and the right is more than the ratio to become the calculated shifting ratio. Therefore, there is a %, which may be downshifted to an area, 4A _ x A or even used to convert one of the AT modes into a table X, which is impossible under Ατ#, 俱. For more specific explanation with reference to Fig. 9, the μ* mapping table is not used in Fig. 9 to calculate 矣 in the AT mode. The other + f舁'^ speed ratio of the normal speed ratio reflects the other aspect, the 诖屮 诖屮 j+ speed shown in Figure 9 (: map γ, ζ description in the corrected AT mode used to calculate the variable force...* In the example of Fig. 9, in order to simplify the explanation, the plurality of gear ratios for the clock speed ratio in the positive AT mode are reflected in the table γ and z. Drawing the gear ratio mapping/situation is as shown in Fig. 9. If the downshifting operation amount is different when the throttle operating member is operated, the downshift correction AT mode is performed. Next, the shifting brother will be used to form the table γ, wherein the gear ratio is exactly shifted by the equivalent amount of the downshift operation calculated by the shift ratio shown in the AT mode to the L mode. 〇W side. ^ W On the other hand, if the calculated downshift operation amount is quite large, then in the downshift correction eight-but mode, use the gear ratio map Z' where the gear ratio is exactly lowered by the heart mode The gear ratio is reflected by the considerable downshift operation calculated by Table X to the L〇w side. In this way, the downshift In the positive eight-but mode, the gear ratio map used to calculate the gear ratio is different depending on the amount of downshift operation calculated. More specifically, 'as the calculated downshift operation becomes larger, The gear ratio correction table used in the downshift correction AT mode is further shifted to the 2' side-reflection table. In other words, with the calculated downshift operation amount; the larger is used in the downshift correction Ατ mode The speed ratio is reflected in the table. 129876.doc 200905107 One step toward a higher engine speed setting. It should be noted that the gear ratio used in the downshift correction AT mode is not limited to the speed ratio. The gear shift used in the AT mode is exactly downshifted: the downshift operation amount calculated in Table X is mapped to the L〇w side. In some cases, the downshift correction Ατ mode is used. The gear ratio used below is not a table of the downshift operation amount calculated by the gear ratio map X to the L〇w side by deflating the gear ratio exactly. For example, this case may be calculated. Occurs when the amount of operation is extremely large. More specifically, the decision will change. The ratio of the derating operation calculated by the gear ratio map X to LOW (four) will increase the engine speed to the engine near the allowable rotation speed (in other words, one of the speed limits) or cause the engine speed to exceed the speed limit. The lower part can set the shift ratio map - the actual change amount is smaller than the calculated downshift operation amount. In this case, the shift ratio map is changed to a maximum allowable downshift operation amount. Specifically, a maximum allowable value is set for the amount of the downshift operation amount, and if the calculated downshift operation amount exceeds the maximum downshift operation; 虿 'the exact gear ratio of the transmission gear mechanism 21 is Downshifting the most operational amount. In other words, 'in this case, the AT mode is corrected in the downshift; the gear ratio map used is to downshift the gear ratio exactly from the shifting table X used in the AT mode. The maximum downshift operation amount is up to and into a table. Training - Detailed explanation of step S3-3 Next, the "established operation fish" condition of step S3_3 will be explained in more detail. , "/, 129876.doc 31 200905107" and "established conditions" * subject to special 'as long as it can determine the driver's acceleration intention or active use, engine, 3⁄4, the map has ended or reduced - Operation and a condition. For example, when at least one of the throttle opening degree, the engine speed, and the vehicle speed meets a predetermined condition, the downshift correction AT mode can be returned to the downshift permitting AT core. More specifically, when the degree of throttle opening is equal to or less than - determines the degree of opening or less than a determined degree of opening, or when the degree of throttle opening has returned to the opening when the downshifting mode is selected: production time, The downshift correction Ατ mode returns to the downshift permitting mode: for example, when the operation amount of the throttle operating member 71 is turned off by more than 20% from the current operating position in terms of the operation amount, the Ατ mode can be corrected from the downshift mode. Return to the downshift to allow AT mode. When the throttle opening degree is constant for a predetermined period of time, the downshift correction AT mode can be returned to the downshift allowable AT mode. Alternatively, the S engine speed may be equal to or greater than a determined rotational speed, or when the engine speed has become greater than a determined engine speed, the downshift positive AT mode may be returned to the downshift allowable τ mode. More specifically, when the speed limit is reached, the downshift corrected AT mode can be returned to the downshift enabled AT mode.

When the vehicle speed is equal to or exceeds a determined vehicle speed or exceeds a determined vehicle speed, it is possible to return from the downshift correction Ατ mode to the downshift δ δ AT mode. When the vehicle acceleration of the motorcycle obtained by distinguishing the vehicle speeds by time is equal to or less than a determined acceleration or less than a determined acceleration, the AT mode can be returned from the downshift correction mode to the downshift permitting AT 129876.doc • 32- 200905107 mode. Further, for example, when the time has elapsed since the selection of the down correction Ατ^ equation has been determined, it is possible to return from the down correction correction mode to the material permission mode. In particular, for example, when the period of _3 seconds to 12G seconds has elapsed since the selection of the downshift correction mode, the mode can be returned from the _corrected AT mode to the downshift allowable at mode.

Further, for example, in the downshift iAT mode, the downshift correction mode can be returned from the downshift correction mode according to the operating state of the brake lever 4c caused by the driver, to the downshift allowing the AT mode. More specifically, when the driver has operated the brake levers, he can return from the downshift correction AT mode to the downshift enable AT mode. Alternatively, when the driver's operation of the brake lever (4) has elapsed - pre-time; t time 胄, the AT mode can be returned from the down-slot correction to the (four)-speed allowable AT mode. Alternatively, when the driver has stopped operating the squats 4c, the downshift correction eight-but mode can be returned to the downshift allowable AT mode. For example, in the case where the engine brake consideration is to be used in parallel, it is particularly advantageous to return from the downshift positive AT mode to the downshift allowable AT mode when the driver stops operating the brake lever 4c. Further, for example, in the s downshift correction AT mode, when the upshift signal 105 is output to the ECU 5 when the driver operates the upshift switch 41, the downshift correction AT mode can be returned to the downshift allowable AT mode. . For example, in the side downshift correction AT mode, when the downshift permission signals 1〇1 to Ecu 5 are output when the driver operates the downshift permit switch 43, 'the return from the "downshift" positive AT mode to the Downshifting allows Ατ mode. "Downshift allows automatic MT mode" 129876.doc • 33- 200905107. In the specific embodiment, as seen from Fig. 5, it is possible to switch from automatic ΜΤ mode to 降 檀 to allow automatic attachment mode. Here, the "downshift allow automatic ΜΤ mode" is a change mode in the downshift permission mode, wherein after the downsizing has been performed in accordance with the operation state of the throttle operating member 71, until the downshift is taken, the hold is lowered. The gear ratio after the gear, and after canceling the downshift, use the normal automatic ΜΤ mode to perform the control. *No, at step S11, when the driver operates the downshift permitting opening 43%' as indicated by W4, the downshift permitting signal 1〇1 is from the downshift permitting switch to the ECU 5. More specifically, the downshift permission signal 1G1 is output to the selection portion 52. When the downshift permit signal 101 is input to the shift mode ", portion 52, the shift mode selection portion 52 shifts from the automatic MT mode to the downshift allows the self-slide type. In other words, when the input downshift allows the signal λ/-change mode selection portion 52 to select the downshift permitting MT mode instead of the gas/pull type. It should be noted that even if the shift to downshift allows the automatic MT mode 1, 1, the control of the speed ratio such as in the normal automatic 逍 mode is performed to perform one of the operations of the throttle operating member 71. : Department's decision to determine whether it has been operated * The throttle operation (4) The salt gate operation signal 113 is shown in Figure 4.

Here, the "downshift allows the manual 咐杈" system - the shifting chess type, in which after the throttle operating member 7 i has been operated, the speed is reduced, as long as the driver does not perform a floor change operation, the shifting wheel The gear ratio of the mechanism 21 is fixed at one of the plurality of predetermined gear ratios. The test chart 12' is, at step S21, when the driver operates the downshift permit switch Ο Ο 3 as shown in Fig. 4, the downshift permit signal ι〇ι is output from the helium allowable switch 43 to the ECU 5. More specifically, the special downshift allow signal 101 is output to the change mode selection portion 52. When the drop 娉 μ, Tian Jiangcai allows the nickname 101 to be input to the shift mode selection portion 5 2, Glycocalyx, strong visual Α, 'type selection ° 卩 52 52 will cause the manual ΜΤ wedge shift to the downshift to allow manual Μ 丄杈 。. In other words, when the input downshift allows 5 noon k 1 0 At 1 o'clock, the shifting grip 10 H selects the portion 52 and selects the material file to allow the MT 杈 instead of the manual Μ 模式 mode. Then 'shown in Fig. 12, in step μ) the glottal operation part (4). More special df Whether the oil operating member sensor 34 has been operated to output to the ECU; 嶋1 1 3 is determined from the throttle throttle operating member signal (1); '::=5 is based on the member 71. In the cow (four) ^ heart has been # throttle operation at At step S22, if it is determined that the routine has been connected, the routine is stopped as the throttle member 71, and the flight proceeds to step S23-1. At step 1 + W3-1, the downshift operation amount is used. And the sickle 51 counts the nasal downshift operation " in the physical example, in the step calculation part 51 reads 23·1, the downshift operation gauge only takes § Recalling the downshift operation amount in the body 57, the I file operation Xia Yingcheng table. The rainy and strange part 51 applies the throttle operation obtained from the throttle door 輙 輙 for the k number 113 I29876.doc -38- 200905107 ::::" The operation amount, the operation speed calculated by the time difference operation amount, the speed obtained from the handle speed signal "2 = the engine speed signal of the engine speed signal (10) to the lowering operation map = this calculation of the downshift operation Note that the "established operation 2" and the "established condition" of the step S23-3 are the same as the "established operation" and the "established condition" for explaining the step of allowing the eight-piece mode of the downshift. In this case, after the step coffee, step MM is executed. At the step coffee, the shifting gear is executed based on the downshift operation amount calculated at the step S23]: the downshift of the speed ratio of the mechanism 21. More specifically, the downshift operation is calculated. The knife 51 outputs the calculated downshift operation amount to the speed ratio control portion 55. The gear ratio control portion 55 lowers the gear ratio of the shift gear mechanism 21 to the gear ratio that is closest to the current gear ratio in the gear ratio of the first speed to the fifth speed. Speed ratio. Thereafter, as indicated by ^, the gear ratio after the down-conversion is maintained. In other words, the downshift state is maintained. ϋ For example, as shown in FIG. 13, in the downshift permitting automatic MT mode, 'If the gear ratio of the shift gear mechanism 21 is operated at the point B (ie, the fifth speed), the oil stays in the shoe 71_ to a relatively small extent. The gear operation amount calculation portion 51 calculates the phase difference small drop operation amount. Then, in the predetermined speed ratio of the first speed to the speed of the speed of the speed of the gear speed, the gear ratio of the downshifting gear mechanism 21 is closest to the slave gear, and the gear ratio of the gear shifting mechanism at the point B is determined by the gear ratio. The amount of operation - the gear ratio of the speed ratio. In the example shown in Fig. 13, the gear ratio is downshifted to the third speed as the = line does not. After the downshift, the shift is maintained at the second speed. 129876.doc -39- 200905107 On the other hand, when the throttle operating member 71 is operated at the point, the hail operation amount calculating portion 51 calculates a considerable downfall, in which the duties are performed. The speed ratio of the first speed to the fifth speed is the closest to the speed ratio of the downshift gear mechanism 21 to the closest from the "less key," "the heart is at the point 8 of the shift gear mechanism side, the exact downshift is calculated (four) In the example shown in the variable U of the first speed ratio, as indicated by the broken line, the gear ratio is downshifted to the first speed. After the downshift, the shift is maintained at the second speed. Ο It should be noted that The downshift allows the manual mode and the upper two to allow the automatic AT mode. The #speed gear mechanism has the gear ratio: when the downshift is calculated, the gear ratio will become the farthest to the LOW side. The predetermined first speed is further down to the L〇w side - the gear ratio is downshifted to the first speed. It should be noted that in this particular embodiment, an explanation - example, wherein the speed ratio control portion 55 in the (four) fixed [speed to fifth speed ratio of the downshift gear The gear ratio of the structure 21 is the gear ratio closest to the gear ratio of the input downshift operation amount which is exactly downshifted from the current gear ratio. However, the present invention is not limited to this configuration. For example, the gear ratio control unit is in the predetermined order. The speed ratio of the first speed to the fifth speed is reduced to the speed ratio of the shifting gear mechanism 21 to the close and to the gear ratio of the shifting ratio of the input downshift operation Alternatively, the speed ratio control portion 55 may lower the speed ratio of the speed change gear mechanism 2 至 to the maximum line in the predetermined speed ratios of the first speed to the fifth speed and to downshift the input downshift from the current speed ratio. The amount of operation - the speed ratio of the speed ratio τ 〇 ρ side. Next, after step S23-2, step S23_3 is performed. At step s23_ 129876.doc -40 - 200905107 3 'determined by the ECU 5 whether it is already on the motorcycle 1Jl β a ^ ^ ^ ^ 』 Both the operation and the satisfaction of one of the established conditions of the motorcycle i. If the predetermined condition is not executed on the motorcycle i in step m3 and the predetermined condition of the motorcycle 1 is not satisfied, the continuation is continued. Use this downshift correction to automatically Μτ On the other hand, if it is determined at step S23-3 that the predetermined fall has been performed on the motorcycle! = the predetermined condition of the motorcycle i has been satisfied, the routine proceeds to step S24. Then, at step S24, The cancel signal 1?7 is outputted from the cancel signal output portion 53 to the down stamp cancel portion 54. Thereby, the downshift is canceled. The shift ratio of the wheel mechanism 21 is changed to the shift speed before the downshift:. Note = 既23.3 "Defined Operation" Xiao "established condition" is the same as "established operation "established condition" in step S3 described in Interpreting the Privacy Reduction Allowed AT Mode. / In step S22, if the throttle operating portion (4) has not been operated, the routine proceeds to step 24 in the same manner. More specifically, at step S22, it is determined that the throttle operating member has been operated. ! In the case of the original, continue to use the gear ratio before the shift to allow the manual Μ τ mode. -: After step S24, step S25 is performed. At step S25, it is determined whether the mode selection switch 44 has been operated and whether the mode selection signal 102 has been output from the mode selection switch 44 to the ECU 5. At step S25, if it is determined that the mode selection signal 1G2JLECU 5 has been output, as shown in Figs. 5 and 12, the descending slot allows the manual MT mode to return to the manual mode. The other side 'right' determines at step S25 that the mode selection signal 102 has not been output to the ECU 5, and the routine returns to #^S22 again. 129876.doc 41 200905107 It should be noted that in this particular embodiment, an example is explained in which the setting is such that when the mode selection signal 1〇2 to pin 5 is rotated, the manual MT mode is returned from the decrement control to the manual mode. The town mode 1 is not limited to this. Also, you J Shikou' in the downshift allowed manual MT mode, when the output downshift enable signal 1〇1 to ECU 5 'can allow manual MT mode from the downshift: to manual MT mode & ° or 'In the downshift allows manual MT mode, when output upshift signal! 05 or downshift signal 1〇6 to £〇1; 5, then ❹ from the downshift allows manual 逍 mode to return to manual MT mode. In other words, at step S25, it can be determined whether the downshift enable signal 101 has been turned on, or whether the upshift k number 105 or the downshift signal 1 已 has been output. In the "Operation and Advantages", door/body embodiment, in the Ατ mode, the downshift command can be pre-operated to 3.4, thereby easily allowing use - extremely simple operation (which is a positive lifting operation, ie The throttle is operated as a hammer 71 to perform a downshift. By:, engine I: performing the descending speed acceleration operation or the active use in the (10) type. In the specific embodiment, the number of the downsizing is calculated according to the operating state of the motorcycle 1 (for example, only the operation amount of the workpiece 71). According to this, it is only possible to downshift the throttle operation state. In other words, the driver is responsible for the number of downshifts based on the operation of the motorcycle 1. 'You can easily adjust the car according to his/her intentions: If you drop the known motor in the Ατ mode and MT mode at the same time, in order to reduce the speed ratio of the gearbox rl motorcycle, '' shouting at least 2 operations, namely: 129876.doc •42- 200905107 ι·Operation-mode selector switch to change mode from ΑΤ mode, and 2. Operate a downshift switch for downshifting. Moreover, in the case of a large downshift of Kadamachi, it is necessary to operate the downshift switch again in addition to the above two operations. This is not only the operation of the gear ratio of the transmission, but also the need to worry about it. In addition, in manual MT mode, incineration batching, right-handling a larger amount of downshifting, more specifically two or more speeds of the speed of the downshift, must perform the shifting operation multiple times. ϋ ϋ In contrast to this, in this embodiment, as described above, the downshift 43 is operable to pre-set the mode, thereby allowing the operation to be performed only (ie, the operation of the throttle operating member 71). A pole operation performed during the period to quickly execute a downshift with the number of downshifts that match the driver's intention. According to this, the driver is able to quickly perform the downshift acceleration operation or active use. The engine teaches the car. ... and in addition, the driver can concentrate more on driving. In addition, in this embodiment, T is not only from the AT mode, but also from the automatic MT mode and manual mt媪彳The shift to the downshift allow mode. Thus, in the automatic MT mode, the master's command is also in the manual MT mode, and similarly, the downshift allow mode can be selected in advance, thereby allowing the normal operation only by performing ( That is, during operation of the throttle operating member 71) Executing - very simple operation to quickly execute a downshift with the number of downshifts of one of the matching driver maps. Further, in this particular embodiment, in the case of y^ 隹, the downshifting operation is sf舁 is zero. More specifically, such as 'in the throttle operating part 71 1 129876.doc • 43 · 200905107 operating quantity system; ^ ^, ^ in a given operation, the specified amount of operation or operating speed is equal to or less than a predetermined operation圮 系 4 4 计算 计算 计算 计算 计算 计算 计算 计算 计算 计算 计算 计算 计算 计算 计算 计算 计算 计算 计算 计算 计算 计算 计算 计算 计算 计算 计算 计算 计算 计算 计算 计算 计算 § § § § § § § § § § § § § § In the case of the downshift operation, the intent of the operator and the beta production: the driving can be performed in a way that reflects the driving skill. It should be noted that even if the throttle operation is the same, if the vehicle speed or engine speed is 丄Γ The fine speed is the same as that of the lowering machine, and in the specific embodiment, not only the operation amount of the throttle operation 4 pieces 71 but also the wear and tear, and Mm will be Vehicle speed and engine speed considerations Calculate the downshift operation amount. Thus, the more favorable downshift operation amount. ° In addition, because the downshift operation amount is used in the calculation of the downshift operation amount, the calculation of the downshift operation amount is easier. Thus, the configuration of the calculation unit 5 1 can be simplified. In this embodiment, in the down-slot correction Ατ mode, the gear ratio is used to calculate the gear ratio of the transmission gear mechanism 21 from the normal mode. The gear ratio calculated by the gear ratio table is + μ. The speed ratio is exactly lower than the downshift operation - only the speed ratio. In other words, in the downshift correction eight-but mode, use (four) Μ (four) (four) speed ratio 'this new gear ratio The reflection will be used in the normal AT mode to calculate the speed change gear mechanism. The gear ratio of the gear ratio is obtained by accurately shifting the downshift operation 瞀 main L 〇 W side. 129876.doc -44- 200905107 Thus, the acceleration effect of the downshift can be utilized over the entire shift speed region. According to this, the motorcycle 1 can be accelerated more smoothly. In addition, in this embodiment, when the predetermined condition has been performed on the motorcycle and the predetermined condition of the motorcycle has been satisfied, the downsizing is cancelled. = This type is executed here, and can be used. - Very simple operation to perform the cancellation of the downslope. Specifically, if used in the throttle opening degree, engine speed and vehicle speed

At least one of the degrees has met the setting for canceling the downshift when a predetermined condition is met, or if the private setting has been passed after the selection of the downshifting permission mode has been passed - the setting of canceling the downsizing during the specified period can be canceled without the driver Perform a special operation. It is especially simple to cancel the amnesty. According to this, the driver is more likely to concentrate on driving. Further, in this case, since a special operation is not required to cancel the downshift, the downshift can be canceled more surely. In other words, it is possible to prevent the cancellation of the downshift due to the driver's insufficient attention and the like. Further, in this case, it is not necessary to specifically provide a return switch for canceling the downshift. Accordingly, the structure of the operation switches can be simplified. Thereby, the cost reduction of the motorcycle 1 can be promoted. Further, in the downshift permission mode, since the downshift setting is canceled depending on the operating state of the brake lever 4c generated by the driver or the driver operates the upshift switch 41 or the downshift permit switch 43, the downshift can be continued. Until the driver does not want to downshift. Then, when the driver wants to cancel the downshift, the downshift is reliably cancelled. In other words, the driver's thoughts can be more reliably reflected. In addition, since the driver's operation of the brake lever 4c is ended, the 129876.doc -45-200905107 is cancelled. Moreover, it is even more effective to actively use the bow I smashing car. Further, the structure of the operation switch can be simplified by using the downshift permit switch 43 or the upshift switch 41 (also as a switch for canceling the downslope). Thereby, the layout of the operational switches can be designed more freely. In addition, it is complicated to prevent the operation of the operation switches. Along with this, the cost of the motorcycle can be reduced. In this particular embodiment, the various types of switches, such as the downshift permit switch 43, are switched by a dust switch. Thus, the driver can easily operate the operation switches. In this embodiment, a push button switch is used to operate the switch. However, such operational switches may also be tie-type switches. b 纟 纟 纟 纟 纟 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , During the manipulation of the motorcycle 1, the driver's thumb is relatively freely moved by comparing the other fingers. Thereby, the operability of the switches of the switches (e.g., downshifting switch 43) can be improved. When the brake levers are held, other fingers can be easily moved, so that it is relatively easy to brake and operate various types of switches at the same time. In this particular embodiment, various types of «_ each of which are provided on the left grip h', such as the downshift permit switch, are on the opposite side of the right grip fc4b. Thus, it is relatively easy to operate the operation switches while operating the throttle. <First Modified Example> The following will explain the modified example of the above specific embodiment. It should be noted that in the modified example explained below, the explanation uses the same reference numerals as those used in the above specific embodiments for structural components having substantially the same functions, and therefore the repeated explanation is omitted. . In the above specific embodiment, an example is explained in which the shift from the Ατ mode to the downshift allow Ατ mode, the automatic MT mode shift to the downshift allow automatic MT mode, and the manual Μτ mode to the downshift to the downshift Manual Μτ mode is allowed. However, the invention is not limited to this configuration. For example, as shown in FIG. 14, a configuration may be employed in which, in the Ατ mode, when the s operation downshift allows the switch 43, the shift to the downshift allows the manual

ΜΤ mode (refer to step s j). In this case, after performing the downsampling after the operation of the throttle operating member 71 at the point a, the gear ratio is based on the calculated amount of the downshift t operation and is expected to be in the plurality of gear ratios. under. In the first modification example, at step s3_3, if it is determined that the predetermined operation has been performed in the motorcycle 1_L or the predetermined condition of the motorcycle 1 has been satisfied, the routine 1 proceeds to step S4. Then, at step S4, at, cancel, and lower the right. Bucowen AT mode shift to downshift allows automatic Μτ mode. Alternatively, the automatic MT shifting to the downshift allows the Ατ mode or the derating to allow the manual MT mode. Alternatively, shifting from manual MT mode to downshifting allows automatic MT mode or downshifting allows eight-but mode. A configuration can be used, in which the driver can select the AT mode in the downshift, the automatic slotting machine allows the automatic Μτ furnace r ATi- -V ^, and the downshift allows the manual MT mode to be selected: The downslope allows the mode. In addition, a set of =Μ drivers can be used to select the downshift permission mode from the automatic MT mode to the downshift permission mode in the downshift allow AT mode, down mode and downshift allow manual mode. In addition, the slick can also be used in a configuration where the driver §; T mode, downshift allows automatic MT mode and downshift allows 129876.doc -47- 200905107 manual MT mode select from manual The MT mode is to change the allowable mode of the downgrade. 11 <Second Modified Example> In the above specific embodiment, an example is explained in which the downshift t m is turned off and the operation is lowered; the switch 43 is allowed to be switched to the downshift permitting mode. However, the invention is not limited to this configuration. In the second modified example;, 胄 explanation - an example in which the downshift permission switch 43 is not separately provided, and the downshift switch 42 is operated to shift to the downshift permission mode. Fig. 16 shows an outline of the overall structure of the section of the handle 4 in the second modified example. In the second modified example, the downshift permit switch 43 is not provided in the switch box 40. Only the upshift switch 41 and the downshift switch 42 are disposed on the left side of the switch box 40. Since the number of switches disposed on the left side of the switch case 4A is less in this manner, the upshift switch 41 and the downshift switch 42 can be made larger than those in the above specific embodiments, respectively. Eight as shown in Figure 17. In this second modified example, the gear can be shifted from the Ατ mode.

U to downshift allows AT mode. However, it is not possible to shift from the automatic MT mode or the manual MT mode to the downshift permission mode. As seen in Fig. 18, in the second modified example, in the AT mode, the downshift signal 丨〇6 outputted by the downshift switch 42 is used as the downshift permission signal '1〇1. In other words, as shown in FIG. 19, in the AT mode, at step S31, when the driver operates the downshift switch 42, the downshift signal 1〇6 as the downshift permission signal 1〇1 is output to the Ecu 5 . When the downshift signal 1〇6 is input to the ECU 5', the downshift permission at mode is selected by the shift mode selection portion. The other steps 82 to S5' are the same as steps S2 to S5 of 129876.doc -48-200905107 explained in the specific embodiment. «Operation and Advantages" In the ^_Modification track example, the groove is switched to the downshift allow mode by operating the down switch π. It is not necessary to separately provide the downshift permit switch 43, so that the upshift switch 41 and the downshift switch 42 can be made larger to this extent, respectively. Accordingly, the driver's operation, ground, and hygiene are improved. In addition, the driver's operating system is easier because the number of operating switches is reduced.第三 Ο <Third Modification Example> In the above specific embodiment, an explanation is given, in which # is output from the hail allow switch 43 to the downshift score &#. At noon b, shift to 101 4 to the downshift allow mode. However, the present invention is not limited to this configuration. For example, as in the third modified example, when the mode selection signal 1〇2 is output from the mode selection switch 44, the downshift permission mode can be shifted. : In particular, as shown in Figure 2〇, the setting can be adopted, in which the AT mode, the downshift permission mode, and the manual mode 2 are more specifically specified when the output mode = (4) 1G2 is in the third modified example. In the Μ mode, when the mode selection signal 102 is output, the mode is switched to the 檑 allowed AT mode. In the downshift enable mode, when the wheel mode selection signal is purchased, it switches to manual = mode. In the manual mode, when the mode _ is ^, the mode is switched to the eight-but mode. Further, in the downshift permission mode, as in the case of -, the door can be used in the embodiment, a configuration can be employed in which the shift to the downshift correction AT mode is performed. In the normal AT mode, when the output is canceled and returned to the lower limit = 1G7, the shift mode may return to the normal mode. In addition, a setting may be employed in which when the downshift permit switch 43 outputs a downshift enable signal (8) instead of the mode select signal from 129876.doc • 49- 200905107, the switch AT mode, the downshift allow mode, and the manual mode are assisted. «Fourth modified example"

In the above specific embodiment, an example is explained in which a Μ mode as well as a manual MT mode and an automatic Μτ mode are selectable. However, the invention is not limited to this configuration. For example, as shown in Figure 21, the -configuration can be used, in which only the AT board type, the drop mode and the down mode correction mode can be selected. In this case, it is not necessary to separately provide, for example, the upshift switch 41 and the downshift switch. Thereby, the downsizing permit switch 43 can be made larger. It should be noted that in the fourth modified example, in the downshift permitting τ mode, the round mode selection signal is returned to the AT mode when it is old. However, in the downshift allowable at mode, it is possible to return to the Ατ mode when the output downshift enable signal is 1〇1. Further, for example, a configuration may be employed in which only one of the automatic μτ mode and the manual ΜΤ mode may be selected in addition to the eight-but mode, the downsizing permit mode, and the down-slot correction mode. And | ' can be configured with a choice of other automatic switching modes than the automatic ΜΤ 与 and manual Μ 模式 modes. <Fifth Modified Example> In the above specific embodiment, as shown in Fig. 2, an explanation is given, in which the falling gate allowing switch 43 is provided in the switch box (4), and the switch box is disposed on the left grip 4a. However, the invention is not limited to this structure. For example, the second downshift permit switch 43 can be placed on the right grip servant as shown in FIG. As in the fifth > I example, the mode selection switch 44 and the downshift enable switch 43 enable, the = off - can be set on the right grip 4b, and the other switches of the other can be set to the left grip Putting it in, thereby allowing the improved mode selection switch 降 and 129876.doc -50- 200905107 to allow the operability of the switch 43. Further, as in the fifth modified example, if the downshift permitting switch 43 is set; on the right grip 4b, the downshift permitting switch 43 is at the position where the finger of the hand operates. Alternatively, the downstairs can be placed at the position where the forefinger of the right hand of the driver can operate. Further, the 'mode selection „44 can be set on the right grip servant, and the lowering allows the switch 43 to be disposed on the left grip 4a. <Other modified examples>

. In the above specific embodiment, an example is explained in which the throttle is separately provided as the component sensor 34 and the throttle opening degree sensing (4). However, in the case where the oil] and the throttle operating member 7 are directly connected by wires or the like, the throttle operating member sensor 34 and the throttle opening degree sensor 33 may be in a sense of the heart U such as 'the throttle opening degree sensing. The device W can also perform the role of the throttle operating member sensor 34. In the above specific embodiment, an example is explained in which a belt type a VT system is used as an electronic control mechanism. However, the 帛 electronically controlled transmission may be a ΡΓντ / , , , ± lte ECVT in addition to a belt type ECVT. For example, the electronically controlled transmission may be a ring type ECVT. In the above specific embodiment, the present invention is explained: an example in which, as an example, a motorcycle is "a pedal type vehicle. However, the straddle type vehicle of the present invention is not limited to the above-mentioned motorcycle. Narrow-type motorcycles, bicycles, off-road vehicles, etc. In addition, the straddle-type vehicle of the present invention may be an ATV (ATV 129876.doc -51 - 200905107. In the above specific embodiment, an example is explained in which various Each of the switches of the type switch (such as the upshift switch 41, the downshift switch 42, the downshift enable switch 43, and the mode selection switch 44) is a push button type switch. However, each type of switch may be a push lever. Each of the switches of the various types of switches may be a rotary switch having a knob that is movable between a plurality of positions.

In the above specific embodiment, an example is explained in which a pWM control motor 22 is used as an actuator for changing the gear ratio of the transmission 2〇. However, in the present invention, the type of the actuator that changes the speed ratio of the transmission 20 is not particularly limited. For example, an actuator that changes the speed ratio of the transmission 2〇 may be a PAM (Pulse Amplitude Modulation) control motor. In addition, the actuation n that changes the speed ratio of the transmission 2〇 may be a stepper motor. Alternatively, the actuator of the shift ratio of the shifting machine may be a hydraulic actuator or the like. In the above specific embodiment, an explanation is given, in which the downshift operation amount is calculated based on the downsampling operation 1 mapping table. However, in the present invention, the calculation method * for calculating the downshift operation amount is particularly limited. For example, the calculation can be performed using a decision function or the like based on the vehicle condition of the motorcycle 1. In the above specific embodiment, an example is explained in which, in the configuration permission mode, as long as the calculated down-construction operation amount does not exceed the maximum destructive operation = as a basic principle, the change from the use in the AT mode τ is used. The ratio is converted to the (four) amount of the gear shift to the exact shift. In other words, in the above specific embodiment, the explanation = in which, in the mode of the subsector, the material - the basic (four), the amount of the downshift operation calculated by the actual downshift is executed. ^, in (4) Allow g 129876.doc -52- 200905107 mode, * must always perform the exact downshift calculation of the downshift operation. : For example, the number of shift ratios used in the downshift mode may be limited. More specifically, if the gear ratio is used in the downshift allowed, the shift ratio is just the same. The gear ratio ratio shown in Fig. 9 is expressed in the table Ζ and Ζ, and in the case where the calculated downshift operation amount is equal to or exceeds a predetermined downshift operation amount, the gear ratio map can be used to calculate the shift speed.

The ratio can be calculated using the gear ratio map γ in the case where the ratio is calculated and the amount of the correction is calculated. In the above specific embodiment, an explanation is given, in which the shift mode is progressively changed each time the mode selection switch 44 is operated. However, for example, a mode selection switch for selecting the ΑΤ mode, a mode for selecting the automatic MT mode @ a mode selection switch, and a mode selection switch for selecting the money mt mode may be separately provided. The cancel switch can be provided separately for canceling the downshift allow mode. here

In the case of It, the downshift is permitted to allow the switch 43 to provide the cancel switch on the left grip 4a. Alternatively, the cancel switch can be provided on the right grip 4b on the opposite side of the downshift permit switch 43. «Second Embodiment" Instead of the transmission 2 in the first embodiment of the invention, as shown in Fig. 23, a transmission 260 including a metal belt as a v-belt can be employed. The components or parts that perform the same operations in the transmission of the embodiment shown in Fig. 4 in Fig. 23 are indicated by the same reference characters. However, the description of the internal components of the ecu 5 has been omitted in the 'FIG. 23' since it is the same as the description in the first embodiment. 129876.doc -53- 200905107 In this embodiment, in addition to including a metal belt 264 as a v-belt, the transmission 260 including a metal belt as a v-belt is modified in various ways (hereinafter also referred to as a "Metal belt cv Ding"), as shown in Figure 2. The metal belt CVT 360 includes a clutch 35, a main rotation sensor 261, hydraulic cylinders 267A, 267B, and a hydraulic control valve 267C. The clutch 35 is disposed between the output shaft 12 of the engine 10 and one of the input shafts 13 of the metal belt c 260. The clutch 35 connects/disconnects power transmission between the output shaft of the engine 1 and the input shaft 13 of one of the metal belts CVT 260. The clutch 35 of this embodiment is an electronically controlled multi-disc clutch. Accordingly, the connection and disconnection of the clutch 35 is automatically performed based on electronic control. When the clutch 35 is engaged, the driving force of the engine 1 is transmitted to the main sheave 23 via the clutch 35. The driving force transmitted to the main sheave 23 is transmitted to the auxiliary sheave 24 via the belt 264. The main rotational speed sensor 2 61 detects the rotational speed of the main sheave 23. The main rotation speed sensor 261 rotates the detected rotation speed of the main sheave 23 to the ECU 5 as a sheave rotation speed signal U4. The main sheave 23 and the auxiliary sheave 24 respectively have a movable sheave body 23a, 24a and a fixed sheave body 23b, 24b. The movable sheave body 23b has a structure that allows movement in the axial direction of the input shaft 13 of the metal belt 260. Further, the movable sheave body 24b has a structure that allows movement in the axial direction of the output shaft 14 of the metal belt CVT 260. The main rotation sensor 261 detects the rotation speed of the main sheave 23. In this embodiment, the ECU 5 uses the rotational speed of the main sheave 129876.doc-54-200905107 23 detected by the main rotation sensor 261 and the straddle type detected by the vehicle speed sensor 32. The ratio of the vehicle speed of the vehicle is used to calculate the gear ratio of the metal belt CVT 260. More specifically, the gear ratio of the metal belt CVT 260 is calculated in the ECU 5 using the ratio of the sheave rotation speed signal 1 14 to the vehicle speed signal 112. It should be noted that the speed ratio of the metal belt CVT 260 can use the rotation speed of the main sheave 23 detected by the main rotation sensor 261 and the sub-groove 24 detected by the sub-groove rotation speed sensor 27. The ratio of the rotational speeds is used to calculate the gear ratio of the metal belt CVT 260. More specifically, the gear ratio of the metal belt CVT 260 can be calculated in the ECU 5 using the ratio of the sheave rotation speed signal 114 to the sub-groove rotation speed signal 111. The hydraulic cylinder 267A adjusts the groove width of the main sheave 23. In this embodiment, the hydraulic cylinder 267A adjusts the groove width of the main sheave 23 by applying a pressure to the movable sheave body 23b of the main sheave 23. Further, the hydraulic cylinder 267B adjusts the groove width of the auxiliary sheave 24. In this embodiment, the hydraulic cylinder 267B adjusts the groove width of the auxiliary sheave 24 by applying a thrust to the movable sheave body 24b of the auxiliary sheave 24. The hydraulic control valve 267C adjusts a valve applied to the hydraulic pressures of the hydraulic cylinders 267A, 267B. The hydraulic pressure control valve 267C performs control such that when the hydraulic pressure of the hydraulic cylinder 267A (267B) of one of the hydraulic cylinders 267A, 267B increases, the hydraulic pressure of the other hydraulic cylinders 267B (267A) decreases. The hydraulic control valve 267C is controlled by the ECU 5. In the metal belt CVT 260, the gear ratio of the metal belt CVT 260 is changed by the ECU 5 operating the hydraulic control valve 267C. The control mode of the ECU 5 is similar to the control mode in the first embodiment. It should be noted that, in the metal belt CVT 260 according to this embodiment, the ECU 5 can use the rotational speed of the main sheave 23 as a control target valve instead of using the engine speed as the control target valve. <Definition of Technical Terms Used in the Specification> The "Shift Mode Selection Section" may select only a part of the AT mode.
