Abstract

When performing kick down, there are occasions when, during re-acceleration after decelerating, the engine races unnecessarily, and a smooth acceleration feeling cannot be obtained. During control by a kick down mode, when accelerating after a throttle has been fully closed, a control target value is set so as not to pass to a Low side of a limit value 400 of the control target value used during re-acceleration. As a result, racing of the engine can be inhibited.

In the main sheave 102, as seen from Fig. 3(b), the gap between the fixed flange and the movable flange 122 is large, and the v-belt 1〇5 is positioned on the inner circumferential side of the main sheave 1〇2. (near the spindle 1〇1). On the other hand, in the secondary sheave, as seen from Fig. 3(c), 'the gap between the fixed flange 123 and the movable flange 124 is small' and the V-belt 1 〇5 is positioned at the secondary sheave rim 04 outside the circumference side. In this state, the rotation of 'spindle 1 〇 1 has been decelerated and is transmitted to the secondary shaft 129443. Doc -12· 200900610 103. Therefore, in this state, the drive has a low speed and a relatively large driving force. Figure 4 (a) shows the stepless transmission 1 处于 when in the top gear (Top). In the main sheave 102, as seen in Figure 4(b), the gap between the fixed flange 121 and the movable flange 122 is small, and the V-belt 1〇5 is positioned outside the main sheave 1〇2 side. On the other hand, in the secondary sheave 1 〇 4, as can be seen from Fig. 4(c), the gap between the fixed flange 1 23 and the movable flange 1 24 is large, and the v-belt 10 is positioned at the time. The inner circumferential side of the stage pulley 1 〇4 (near the secondary shaft 1 〇3). In this state, the rotation of the spindle 101 has been increased and is transmitted to the secondary shaft 103. Therefore, in this state, the drive has a high speed and a relatively small driving force. Stepless speed change! 00 drives the motor 106 according to the target value setting program preset in the control device 1〇7, and thereby adjusts the groove width of the main sheave 102 to adjust the underspeed ratio when the stomach performs the change of the low speed Tan according to the rider's intention. The low speed building' is achieved using the control based on the target value setting program. The inventor has confirmed that when the V-belt type stepless speed changer with this type of shifting low speed is used for the field, the right engine is assigned to the low speed when the speed is accelerated again after the deceleration, the engine exists. The situation of acceleration. Unnecessary slamming causes unevenness The problem described above is symmetrical. However, the inventor has. ...

Referring to Fig. 2, in this embodiment, the straddle type vehicle 1 includes an accelerator operating member 131 and an exchange lower speed operating member 132. The accelerator operating member 131 is an operating member used by the rider to control the output of the engine 1〇8. In this embodiment, the accelerator operating member 131 is formed by an acceleration attached to the handle or an accelerator handle. As can be seen from Fig. 1, the 装置-device 1 〇 7 controls the degree of opening of the throttle i ^ according to the operation of the accelerator operating member 131, thereby controlling the output of the engine 108. The swapping of the low speed slot operating member 132 is operated by the rider and is an operating member that performs the shifting of the downshift mode, as described below. In this embodiment, the exchange of the low speed slot operating member 132 and the accelerator operating member ΐ3ι respectively provides 'and can be, for example, positioned at a position at a position that takes into account rider operability and is easy for the rider to operate, that is, swaps the low speed slot. Press the peak D button). The control device H) 7 performs the adjustment of the low gear mode in accordance with the operation of the rider to switch the lower gear operating member 132. As shown in Fig. 1, the 'stepless speed changer_ is connected to the engine (10)' and the control unit 107 is provided. .

Among these sensors, the 'accelerator operation sensor ΐ5 is (4) a sensor for information on the operation of the accelerator operating member 131. The valve opening degree sensor 152 is a sensor that detects the degree of opening of the throttle. In this embodiment, the throttle opening degree sensor 152 is provided at the axis of the throttle (1), and detects the rotation angle of the throttle (1) as the throttle level. The engine speed sensor 153 is detecting. In this embodiment, the engine speed sensor 153 is provided near the engine shank (spindle ΗΗ) to measure the engine speed. The secondary sheave rotation speed sensor 154 is a sensor that detects the rotational speed of the secondary sheave 104. In this embodiment, the secondary sheave rotational speed sensor 154 is provided adjacent the secondary shaft ι3 and detects the rotational speed of the secondary sheave 104. In addition, the vehicle speed sensor 15 5 is a sensory sense for detecting the running speed of the straddle type vehicle. In this embodiment, the vehicle speed sensor 155 is provided on the drive shaft of the drive wheel ι 4 and detects the rotational speed of the drive shaft of the drive wheel 114. For example, the vehicle speed (operating speed) of the straddle type vehicle 1 can be detected based on the rotational speed of the driving shaft of the driving wheel ι 4 detected by the vehicle speed sensor 155. The normal mode 200, the reverse low gear mode 3, and the limit value 400 for the control target value used when re-accelerating are stored in the control unit 丨〇7. Further, in this embodiment, the limit value 5 used when the throttle is completely closed is also memorized in the control unit 107. Note that in this embodiment, control 129443. Doc 15 200900610 Value 2 Control Plant Control Target Value of Stepless Transmission 100 Value = Township Target Value Setting Section 14. Provided in the memory portion of the control device 1〇7. The normal mode coffee, the low speed mode is changed: the limit value of the control target value used when re-accelerating is 4〇〇 and the limit value 500 used when the throttle is completely closed is set in the target value setting portion 1 4 0, respectively. . In this case, the normal mode is programmed with the control target value used during normal operation when the low speed flag is not executed. The shifting of the low speed mode 300 sets the control target value when the shifting of the low gear is performed such that the control target value is low compared to the normal mode. The normal mode 2 (8) and the exchanged low gear mode 300 are respectively stored in the memory portion of the control device 1〇7, and are programs for setting the control target value for the control device 1 to 7. The normal mode 200 and the reversed low gear mode 3 are based on the throttle opening degree sensor 152, the engine speed sensor 153, the secondary sheave rotation speed sensor 154, the vehicle speed sensor 155, and the like, respectively. Vehicle information to determine the control target value. The control unit 07 drives the motor 106 based on the control target value described above, thereby controlling the groove width of the main sheave 1 〇2. Further, in this embodiment, the normal mode 2 sets the control target value to the engine speed for the vehicle speed, and controls the speed ratio of the stepless transmission i 达成 to achieve a given control target value. The low speed mode is switched, and the target value for the engine speed set by the normal mode 200 is multiplied by a predetermined odd ratio (down ratio), thereby setting the control target value to be in the normal mode. The ratio is low. In response to the operation of switching the low speed operating member 1 32, the control device i 〇 7 makes 129443. Doc -16- 200900610 The control target value is set by the normal mode 200 instead of the normal mode 200 set by the target value setting section 140. The limit value of the control target value used during word re-acceleration is set to the limit value of the stepless speed change / &amp; target value set when the king is closed or the valve is accelerated. Here, the phrase, the fully enclosed throttle/S is more specifically § the execution-operation, in which the throttle (accelerator) is opened after the throttle has been decelerated to accelerate. In this actual target example, when the control target value is set by switching the low gear mode, the limit value of the control target value used during the re-acceleration plays a role. More specifically, in this embodiment, in the normal mode, considering the efficiency of the material efficiency, etc., the control target value of the stepless transmission 1 is set so that the engine does not suddenly turn. In contrast, the shifting of the low gear mode is performed by multiplying the shifting characteristic (speed ratio) of the JL normal mode by a constant ratio to set the target value. Therefore, the problem of engine jerk may occur. The limit value 4〇〇 of the control target value used during the re-acceleration is set to a control target value that appropriately controls the stepless transmission 1 so that the engine does not suddenly rotate. Note that here, the phrase "limit value of the value of the '" used during re-acceleration indicates that the stepless transmission is appropriately controlled in order to suppress the control target value of the above-described engine jerk. The phrase is not a sound engine limiter. ° For example, the limit value of the control target value used during the re-acceleration can be set based on a pre-tested straddle-type vehicle with a phase changer type 400, and set it to properly control the stepless machine 100 so that 129443 will not be issued when re-accelerating after completely closing the throttle.

At the same time, it is considered to suppress the occurrence of the engine brake action when the throttle is decelerated when the throttle damper is closed. The efficiency of the sliding of the V-belt 105 is the main groove of the segment transmission Η). The limits described above can be set, taking into account, for example, the results of simulations or tests on actual devices. Note that although in this embodiment A, the limit value 500 used when the throttle is completely closed is set as described above, it is not necessary to set the limit value 5 使用 used when the throttle is completely closed. 5 shows the normal mode 2〇〇 set in the target value setting section 14A, the swapping downshift mode 300, the limit value 400 of the control target value used during the re-acceleration, and the limit used when the throttle is completely closed.

More specifically, the vertical axis of Figure 5 shows the engine speed and the horizontal axis shows the vehicle speed. As can be seen from Fig. 5, 'If the wheel speed is the same, when the engine speed becomes high', the gear ratio of the stepless speed changer is controlled to change toward the L〇w side. Further, if the engine speed is the same, when the vehicle speed becomes slow, the speed ratio of the stepless speed changer is controlled to change toward the Low side. 129443.

In the example of the doc 200900610, each time the rider operates the reverse speed operation member i32, the control target value is gradually set to the reverse low speed mode on the l(10) side in accordance with the operation of the rider, whereby the downshift is gradually performed. , _ field using the normal mode 2 of the above description, or switching the low speed 楷 mode (301 3G2, 3G3), using the calculation based on the information about the vehicle speed and the degree of throttle opening to derive the engine speed control target value . More specifically (4), the base 9 determines the position on the horizontal axis of FIG. 5 with respect to the vehicle speed information. In addition, the engine speed control target value is set by multiplication using a determination coefficient corresponding to the degree of opening of the throttle (accelerator). The control target value (2〇〇a, s, 302a, 3G3a) used when the throttle is completely closed and the control target value (2_, 3() lb, 3G2b, used when the throttle is fully opened. In this case, when the degree of opening of the throttle becomes small, the control target value is set closer to the control target value (2〇〇a, 3〇u, 3〇3a) used when the throttle is completely closed. When the degree of opening of the throttle becomes large, the control target value is set closer to the control target value (200b, 301b, 302b, 303b) used when the throttle is fully opened. The control device 1〇7 uses the wheel speed and the throttle. The information of the temporary change in the degree of opening of the door repeatedly performs calculation and continuously updates the control target value of the engine speed, thereby controlling the gear ratio of the stepless transmission 1〇〇. In this embodiment, A suppresses the engine from slamming, To achieve smooth acceleration when accelerating after the throttle η has been completely closed, the control device 1〇7 executes the first control 701, the second control 702, and the third control 7〇3. In the first control 701, when the low speed configuration is switched Mode 3 控制 control period 129443. Doc -22, 200900610 When the acceleration is completed after the throttle is completely closed, the target value setting portion 14 controls the target value so that the control target value used during the re-acceleration: the limit value 400 does not exceed the L〇w side. In this embodiment, 'in the first control 〇1, when the reverse speed slot mode 300 is set to set the control target value closer to the heart side than the control target value ^limit value used during the re-acceleration, the control target value is set. Set to control 2 standard value. However, when the low speed floor mode is switched, the control target value is set: when the limit value 400 of the control target value used during the re-acceleration is set to be close to the Low side, the limit value 400 of the control target value used during the re-acceleration is set to Control the target value. Next, the control flow of the first control 〇1 described above will be explained with reference to FIG. 1 In the first control 701, first, at the determining step (su), it is determined whether or not the accelerator is turned off during the control of the shifting of the downshift mode 300. It may be determined whether the switching of the low gear mode 3 is currently being performed based on, for example, information regarding the performance of the switching of the low gear control in accordance with the operation of shifting the low speed operating member 丨32. In addition, the accelerator can be determined to be disconnected based on information from the accelerator operating sensor 15 or its analog. If it is determined at the determining step (S11) that &quot;yes&quot;, the routine proceeds to the next reading step (S12). However, if the determination at the determining step (S11) is "NO", the first control 70 1 is ended. At the determining step (S12), it is determined whether the vehicle is accelerating after the throttle has been completely closed. In the example, it is determined that the throttle has been completely closed 0 129443 based on whether a switch from the accelerator off to the accelerator on has occurred. Doc •23- 200900610 Whether the vehicle is accelerating. Whether the p-path occurs from the accelerator disconnection to the accelerator switch-on can be determined based on information from the ball-fed sensor 151. If it is determined at the disc setting step (SU), no &quot;, then the steps (8) 6) described below are performed, and in step (S16), it is set in the switching low speed mode when the throttle is completely closed. The control target value of the material speed is set to the last control target value of the engine speed. If YES is determined at the determining step (8) 2), the routine proceeds to the next step (S13). At step (S13), the control target private value set by switching the low gear mode 3 is updated. More specifically, in this embodiment, at step (S13), the control target value of the engine speed set by the shifting downshift mode 300 used when the accelerator is switched to the ON state is calculated, and is set to Updated control target value. Next, a determining step (s 14) is performed. At the determining step (S 14), it is determined whether the control target value of the engine speed updated at the step (S13) is greater than the limit value 400 of the control target value used during the re-acceleration. In other words, it is determined whether or not the control target value set by switching the low gear mode 3 is closer to the L〇w side than the limit value 400 of the control target value used during the re-acceleration. If it is determined as &quot;No&quot; at the determining step (S14), the control target value of the engine speed updated at the step (S13) is not greater than the limit value of the control target value used during the re-acceleration. In this case, the given control target value updated at (S 1 3) is set as the control target value (S 16). If it is determined as "Yes" at the determining step (S 14), the control target value of the engine speed updated at the step (S 13) is greater than the control used during the re-acceleration. Doc -24- 200900610 The limit value of the target value is 400. In this case, the steps are executed (S15). The step (" is a step of setting the control 4〇〇 used during the re-acceleration to the control target value. The meaning of ^, , α, is not by changing the control target value of the engine speed determined by the low-power itr, but Re-limit value of the control target value used in the period 1 is set as the control 1 as a result of the step (S15), the limit value 400 of the control target value used during the re-acceleration becomes the control target value. In the step (SI6) At the position described above, the processing of the step (8) 2), the step (8) 4), and the step (Si5) sets the control target value of the stepless speed changer (10). Next, the first control will be described with reference to FIG. 5. Referring to Figure 5, when, for example, the throttle is closed during normal operation (under the control of the normal mode) to decelerate during normal operation (the control of the normal mode), the rider can sometimes repeatedly operate the reverse speed (four) member 132 so that Increase the effect of engine braking. 曰 For example, 'If you perform three times to change the low-speed building control, as indicated by arrows 3 to C shown in Figure 5, the used low-speed control will change from the first to the low-speed. mode 3〇1 shifts to the second shifting low gear mode 3〇2, to the third shifting low gear mode 303. Then, as indicated by the arrow d, when the vehicle decelerates, it will continue to change the low gear mode according to the third shift 3〇3 The stomach pressure value is set. In this embodiment, as described above, the limit value 500 used when the throttle is completely closed is set. If the throttle is decelerated, the section set by the low gear mode 300 is set. The control target value of the transmission i 超过 exceeds the preparation number 129443. Doc •25- 200900610 The limit side of the limit value of 500 used in the fully enclosed throttle is controlled by the setting of 07. The control target value of the stepless transmission 1 设定 is set to the limit used when the throttle is completely closed. The value is 5〇〇. ί Accordingly, in this embodiment, under the control of the third shifting downshift mode 303, if the throttle speed is set, the control target value 303a of the engine speed is reduced to the vehicle speed and thus exceeds when the throttle is completely closed. At the L〇w side of the limit value 500 used at the time, the limit value 5GG used when the throttle is completely closed is set as the control target value of the stepless transmission (10). As indicated by an arrow e, the control target value of the stepless transmission 1 is set based on the limit value 500 used when the throttle is completely closed. The first control 701 is executed while the acceleration of the fully closed throttle is under control under the switching of the low gear mode described above. Therefore, if the arrow e is not used, it is based on the =: value used when the throttle is completely closed, and the accelerator is switched from off to on.

When switching to ON and opening the throttle, it is effective. The limit imposed by the limit value used by ί is not worthwhile. Therefore, "Arrow: Γ奂 low gear mode 303 sets the control target plus. W, no, the control target value of the 丨 丨 速度 speed increases beyond the control of the heavy 迷 标 模式 mode 303 setting Μ L (10) side, then the use of the text The limit value of the control target value · The control target used by Tian Shuzhi's first control 701 sets the limit value of the &amp; value to the control target value during the re-acceleration period. This is I29443.doc -26 - 200900610 by Figure 6 The determination process of the determining step (S14) shown in the above is performed. Therefore, if the control target value set by the third shifting low gear mode 3〇3 exceeds the limit value 400 of the control target value used during the re-acceleration period, Low On the side, the limit value 4〇〇 of the control target value used during the re-acceleration is set as the control target value' as indicated by the arrow g in Fig. 5. Therefore, the control target value of the stepless transmission 100 cannot exceed Below and set to the L〇w side of the limit value of the control target value used during the re-acceleration period. Note that the control target value set by the second shift low-speed mode 303 does not exceed the re-acceleration period. Make In the case where the limit value of the control target value is 4〇, the control target value set by the third shifting downshift mode 303 is set as the control target value. As described above, in the first control 701 By the determining process of the determining step (S 14), when the control target value set by switching the low gear mode 3 超过 exceeds the top side of the limit value 400 of the control target value used during the re-acceleration period, it will be given The control target value is set as the control target value. However, when the control target value set by switching the low-speed mode 300 exceeds the limit value 4〇〇 of the control target value used during the re-acceleration period, the re-acceleration is performed. The limit value 400 of the control target value used during the period is set as the control target value. Therefore, the control target value cannot exceed the lower limit and is set to the L〇w side of the limit value 4 of the control target value used in the re-acceleration period. Therefore, when the acceleration after the throttle has been completely closed under the control of the shifting of the low-speed mode, the stepless transmission 100 can be controlled so that the target value during the re-acceleration is The value of 4 〇〇 does not exceed l 〇w side, and therefore can suppress? 丨 猛 。. 129443.doc -27- 200900610 二意 'In Figure 5' when not performing the shifting low gear control in normal = ( Under the control of the normal mode) to close the throttle to reduce:: = can be repeatedly operated to exchange the low-speed operation member m :=. The first one described above can play a role in the situation different from = brother Lifting, τ ^ σ Tian is in control of the low-speed mode control in the closing of the rolling door (accelerator) to decelerate - Λ,,, ± 疋 button to open the nipple (acceleration ° 忪, the first described above Control 7〇1 can also work.

The above description completes the description of the first control 〇1. In the above embodiment, the field setting of the plurality of levels of the low-speed slot mode is set in the target value setting portion (4). Bran # (3) exemplified only, however, 'when accelerating after the throttle has been completely closed under the control of the shifting of the low gear mode, the first control system described above has no # and the gearbox 100 is used for re-acceleration. The limit value of the control target value is 4〇〇 and does not exceed the L〇w side. Therefore, in the target value setting portion 140, it is not essential to set the switching of the low-speed mode of the plurality of levels. Next, the second control 702 will be explained. When a plurality of levels of shifting low speed difficult modes are set in the target value setting portion 14A as in the embodiment described above, generally, the vehicle is completely closed after the throttle is controlled during the shifting of the low gear mode When accelerating, maintain the shifting low gear mode used before the acceleration. At this time, if the reverse low speed control has been used a plurality of times before the acceleration, there is a case where the use of the other reverse low speed is restricted after the enchantment. When the sundial is accelerated after the throttle has been completely closed during the control of shifting the low gear mode 3, the second control 7 0 2 is used by using the plurality of levels 129443.doc • 28 - 200900610 for the low gear mode The setting in 300 is the switching downshift mode 300 closest to the τ〇ρ side to set the control target value. In other words, in this embodiment, when the acceleration is completed after the throttle is fully closed during the control of the reverse low speed mode 300, the setting among the plurality of shifting low gear modes 3 (8) is the closest to the Top side. Change the low gear mode 3〇〇 to set the control target value. Therefore, after the acceleration, it is possible to change the low gear again in response to the rider's request. Next, the control flow of the second control 7〇2 will be explained based on FIG. In the second control 702, first, at the determining step (S21), it is determined whether or not the accelerator is turned off during the control of switching the downshift mode 300. If YES is determined at the determining step (821), the routine proceeds to the next determining step (S22). However, if it is determined at the determining step (S21), no &quot;, the second control 702 is ended. At the determining step (S22), it is determined whether the vehicle is accelerating after the throttle has been completely closed. Note that in the example of Fig. 7, whether or not the vehicle is accelerating after the throttle has been completely closed is determined based on whether or not a switch from the accelerator off to the accelerator on has occurred. If it is determined as "No" at the determining step (S22), the control target value set under the control of the given shifting of the low gear mode is set as the last control target. The target value (S25). The determination step (S22) is determined to be "," and the routine proceeds to the next step (S23). At the V-thres (S23), the shift from the low-speed mode shift to the plurality of shifts in the low-speed building mode (H) is set to the first-switching low-speed (four) type closest to the T〇P side. Indeed, in this embodiment 129443.doc -29-200900610 'at step (S23)', when the accelerator is switched on, the used shifting low gear mode is shifted to the plurality of levels. Among the low gear modes (301, 302, 303), the first shifting downshift mode 301 is set closest to the τ〇ρ side. Next, the routine proceeds to step (S24). At the step (S24), the control target value is calculated using the shift to the first shifting downshift mode at the step (S23). At the step (S25), the control target value is set based on the processing at the determining step (S22) and the step (S24) described above. More specifically, when it is determined at step (S22) that the vehicle is accelerating after the throttle has been completely closed, the low gear mode shift is shifted to the first reverse low gear mode 301 at step (S23). Next, at step (S24), mode 301 is used to calculate the control target value, and at 24) 'by first shifting the low gear and at step (S25), setting the last control target of the stepless transmission 100 value. Next, the second control 7〇2 will be explained with reference to FIG. In the figure, for example, during normal acceleration (four) deceleration without performing the exchange of the low speed slot control, the rider sometimes repeatedly operates the low speed standard operation member 132 to increase the effect of the engine brake.

Run_ (i.e., 'under the control of the normal mode fine in this embodiment) is closed 129443.doc -30- 200900610 In this embodiment t, as described above, the limit value 500 used when the throttle is completely closed is set. Therefore, if the control target value 303a set by the third shifting downshift mode exceeds the Low side of the limit value 500 used when the throttle is completely closed, the "limit value 500" when the throttle is completely closed is set to Controlling the target value (arrow illusion. When accelerating after the throttle has been completely closed during the control of shifting the low gear mode, the second control 702 is performed. Therefore, as indicated by the arrow e... when the accelerator is switched from off to on, When the control target value is set according to the limit value 5〇0 used when the throttle valve is completely closed: w, when the accelerator is switched from off to on, the throttle is opened, and when the throttle is completely closed The limit value established when the gate is used is not valid. Then, as shown in FIG. 7, as a result of the determination of the second control 7〇2, the step (S23) is performed, thereby switching the low speed. The mode shifts to the first-shifting low-speed mode 3〇 1. Next, the control target value is set by the first shifting low-speed mode 301 (S24, S25, by the accelerator operating member) It is determined that the control target value is set by the first setting of the drag down mode 301, as indicated by the arrow h in Fig. 8. At this time, the rider (4) is appropriate, and the operable member 131 is added to increase the engine. In addition, the rider can operate the low-key component 132 to request another-(four) (four) low-slot fine ± 5 weeks to change the low gear. According to the second control, the acceleration speed is adjusted, and the low-speed mode is switched from the second. ... ^ From the first change to the low gear mode 303 change _ $ brother - change the low gear mode 3 () Therefore, the town in the Mingyi another change the low 129443.doc -31 - 200900610 speed standard situation, change the low speed slot The mode is automatically changed from the first (four) low speed slot mode 30! to the second reverse low speed mode 3〇2, to the third reversed low speed mode 303. In this way, the second control 702 causes t to change the low speed. In the control mode of the slot mode 3〇〇, after the fully closed section t gate is added, the position of the low speed TM, 3, 2, 3 〇 3) is added: = the shifting low gear mode close to the Top side sets the control target value. After the acceleration, it is possible to respond to the change from the rider. In addition, as shown by the arrow in Fig. 8, the control target value of the engine speed set by the first exchange low speed standard mode 3〇1 and the low speed mode by the third exchange mode The control target value of the engine speed set by 303 is low. Therefore, it can be expected that the second control 702 will be effective in suppressing the engine slamming. In addition, it is completely closed during the control of switching the low gear mode 3〇〇. The second control 7〇2 acts when the throttle is accelerated. For example, as indicated by the dashed arrow hl shown in Fig. 8, when the throttle is closed during the control of the third exchange low speed mode 303 ( The second control 7〇2 can function when the accelerator is opened after deceleration to open the throttle (accelerator). In the case of j, due to the use of the second control 7〇2, it is possible to return to the bank from the request of the low-speed target from the rider after the acceleration and once the shift to the first-shifting low-speed mode 3〇1 has occurred. Change the low speed broadcast. Further, since the second control 7〇2 is used, the control target value of the set engine speed is lower than the control target value when the control of the three-shift low-speed broadcast mode 3〇3 is performed. Therefore, it can be expected that the second control 7〇2 will be effective in suppressing the engine 129443.doc -32· 200900610. ...the above describes the description of Yuancheng's second control 7〇2. You can modify the brother-in-control 7 0 2 in various ways. For example, in the above description, an example is given in which, at the step (S23) in the control flow shown in FIG. 7, control is performed to shift the reverse low gear mode to the first reverse low gear mode. 3, however, instead: the step 'at step (S23)' can shift the shifting low gear mode to the plurality of shifting low gear modes (3〇1, 3〇2, 3〇3) The shifting low gear mode is set closer to the Top side than the downshift mode used immediately before the acceleration after the throttle valve has been completely closed. According to this control, after the acceleration after the throttle has been completely closed, there is a possibility of responding to the request from the rider to perform another change of the low gear to change the speed. In addition, it is possible to suppress an unnecessary engine jerk as compared with the case of continuing to use the shifting downshift mode used immediately after the force speed after the throttle valve has been completely closed. In the case where the control is performed during the control of the low-speed broadcast mode 300, after the throttle has been completely closed, the shift of the low-speed control can be lost, for example, and the normal mode 200 can be used. However, under this control, the shifting of the low gear is disabled because of the desire to violate the counterfeit, so it is impossible to obtain the torque satisfying the rider's intention when accelerating, and thus smooth acceleration is not achieved. The first described above - Control 7 〇 2 allows for smooth acceleration based on the rider's intent and allows suppression of unwanted engine jerk. Further, the second control 129443.doc -33·200900610 can be used to control the no-segment by using the first control 7〇1 set by the limit value 400 of the control target value used during the re-acceleration described above. The transmission 100 is such that when accelerated after the throttle has been completely closed, the limit value 400 of the control target value used during re-acceleration is not exceeded. Note that the use of the second control is not essential in combination with the first control 7〇1 set by the limit value 400 of the control target value used during the re-acceleration described above. Further, the limit value 5 设定 used when the throttle is completely closed as described in the above embodiment is not essential. (Next, the third control 703 will be explained. For example, when the second control 7〇2 described above is activated, the shifting of the low gear mode is shifted to the shifting low gear set to be closer to the τ〇ρ side. The mode is thus exemplified. If the control shifts from the third shifting downshift mode 3 〇3 to the first shifting downshift mode 3〇1, as indicated by the arrow hi in FIG. 8, the engine speed is controlled. The control target value becomes lower. Therefore, in the case of accelerating after the throttle is completely closed, when accelerating, the output torque is too small to satisfy the rider's intention, and therefore it is possible that the vehicle C will not be smoother than the rider wishes. Acceleration. In the third control 703, the above-described difficulties that occur when the second control 7〇2 is used are solved, and the control is performed such that the vehicle accelerates smoothly when the throttle is fully closed. The second control 703 sets the control target value such that the control target value of, for example, the engine speed is not temporarily lowered immediately after the acceleration. Further, for example, advantageously, the third control 7〇3 is set The gear ratio is controlled so that it does not temporarily change to the τ〇ρ side immediately after the acceleration. In this case, for example, the timer function of the control device 1〇7 can be used 129443.doc • 34- 200900610. Then, the hold/time period can be counted after the throttle has been completely closed, and the stepless shift can be maintained during the preset time period so that the second control 7° 2 is used immediately after the acceleration. There is no segmentation, and the target value of the system is not set to be excessively encountered immediately after the acceleration. Therefore, when accelerating, it is possible to output a torque that better matches the intention of the rider and achieve smooth acceleration. In the following, an embodiment of the above third control 703 will be described. In this embodiment, when the acceleration is performed, if the control target value of the 2 engine speed is set by switching the low speed standard mode and immediately before the acceleration and is not fully opened That is, when the control target value of the engine speed used in the trick is low, the value of the control of the engine speed used immediately before the acceleration is maintained when accelerating until the low speed mode is changed. The set target value of the engine speed is set to exceed the control target value of the engine speed used immediately before the acceleration: In this embodiment, in the flowchart of the second control shown in, for example, FIG. The third control 3 is set between the step (S24) and the step (S25). Fig. 9 shows an example in which the third control 703 of this embodiment is set between the step (S24) and the step (S25) of Fig. 7. In this embodiment, after the step (S24), the determining step (S3 1) is performed. At the determining step (S31), it is determined whether the control target value of the engine speed set immediately before the acceleration is higher than by the acceleration Immediately change the floor to the control target value of the engine speed set in the low gear mode. Note: In Fig. 9, for the sake of convenience, the engine will be set immediately before the acceleration. 129443.doc -35- 200900610 Speed control target The value is expressed as &quot;target engine speed immediately before acceleration' and the control target value of the engine speed set by shifting to the low speed mode immediately after acceleration is expressed as &quot; immediately following the acceleration · Engine speed '.

The control target value of the engine speed set immediately before the acceleration is higher than the control target value of the engine speed set by the swapping the low speed slot mode immediately after the acceleration, and the determination step (S3 1) is determined as &quot; is &quot;. If it is determined to be "YES" at the determining step (S31), the following steps are performed. At the determining step (S32), it is determined whether the throttle (accelerator) is completely fired. If the control target value of the engine speed immediately after the acceleration is higher than the speed of the speed, the shift is shifted to the low speed mode setting. If the engine speed is controlled to the target value and the throttle (accelerator) is not fully opened, it is determined that the determination at step (S32) is "Yes, and at the determining step (s32), it is determined as "Yes"" Step (S33:). At v (S33), the control target value of the engine speed immediately before the acceleration is set as the control target value. The change of the engine's target value set immediately before the acceleration is higher than the control target value set by the shifting to the low-speed slot mode immediately after the acceleration, and the throttle is not fully opened ( Accelerator) ^, sets the control target value of the engine speed set immediately before the acceleration to the control target value. The aspect t is determined to be no at the confirmation step (S31) or the determination step (8) 2), then the steps are performed in both cases (S34 σ σ '' immediately before the acceleration The control target of the catch I29443.doc &gt;36- 200900610 The value is not _ when the shift is immediately shifted to the control target value of the engine speed set by the low-speed slot mode, the step (s34) is executed. The control target value of the engine speed set before the acceleration is higher than the control target value of the engine speed set by the swapping of the low gear mode immediately after the acceleration and the step is performed in a similar manner when the accelerator is fully turned on (S34). At the determining step (S34), the shift to the tone immediately after the acceleration is used

The control target value of the engine speed set in the low speed implant mode is set to the control target value. At step (S25), although not shown in the drawing, the control target value is set based on the processing of the determining step (S22), the step (S33), and the step (S34) described above. Next, Fig. 8 will be used as a basis for explaining the case where the second control 7〇2 and the first control are used: 〇3. For example, when accelerating after the throttle gate has been completely closed, there is a second control 702 setting the control target of the engine speed: the condition ' as indicated by the arrow hl. In this case, the control target value of the engine speed set immediately before the acceleration is higher than the control target of the engine speed set by the shifting to the low speed mode immediately after the acceleration, so the second control 7〇3 effect. When the third control 7〇3 is active, the target value of 'maintaining the engine speed' is maintained until the control target value of the engine speed set by the low-speed mode is higher than immediately after the catch is reached. The control target value of the engine speed set before the acceleration is as indicated by the arrow i. In the case of using the third control 703, even if the second control 129443.doc -37-200900610 is used, the control target value of the stepless transmission 100 will not be immediately after the acceleration. It is set too far from the Low side. Therefore, when accelerating, a force 9 that matches the intent of the rider can be output, thus allowing smooth acceleration to be achieved. Note that the control target value 3 of the engine speed that completely closes the throttle valve % in the third shifting low gear mode 3〇3 is higher than when the throttle valve is fully opened in the first shifting low gear mode 301. The situation is slightly different under the condition of the position of the control target value 301a of the set engine speed. In the case of the cow, σ considers the state indicated by j on the solid line 3 03 a, and the solid line 303a does not cover the control target value set by the third shifting low speed mode 303 when the throttle is fully closed. In this case, at the vehicle speed in the state indicated by j in FIG. 8, the control target value 303a set by the third shifting downshift mode 3〇3 when the throttle is completely closed is higher than when fully opened. At the throttle, the control target value of the engine speed set by the first shifting of the low shift mode 301 is as follows. " Next, consider this case: under the control of the third shifting low speed 〇 mode 3 〇 3, the accelerator is closed to decelerate, and Then, the accelerator is fully opened to accelerate in the state indicated by the state in Fig. 8.
