Description

200900609 IX. Description of the invention: [Technical field to which the invention pertains] The present invention relates to a straddle-type vehicle (for example, a motorcycle), a power early warning system, and a type of stepless speed-shifting mobile practitioner. It relates to a straddle-type vehicle equipped with an electronically controlled stepless speed changer. [Prior Art] In the straddle type vehicle of the Scooter type motorcycle, the ¥ shape 1 stepless speed change machine is widely used. The output of the v-belt type stepless speed change is input to the main shaft, and the drive to be driven to the drive t _ knife is placed on the main shaft and the pair of main and auxiliary sheaves on the countershaft. The slot width of each of the 寻 寻 糟 轮 经 is designed to be variable, and the tribute wraps around the sheaves. The V-belt type stepless speed changer has a groove width adjustment mechanism for changing the groove width of each sheave. Therefore, the winding diameter of the v-shaped leather armor of each of the grooves is adjusted to be circumscribed, and the gear ratio between the sheaves is adjusted in a stepless manner. The main sling and the auxiliary sheave are formed by a fixed flange and a movable flange, and a V-shaped groove is formed between the fixed flange and the movable flange. Each movable flange is provided such that it can move in the axial direction of the main or sub-shaft. The groove width adjustment mechanism moves the movable flange to adjust the gear ratio in a _stepless variable manner. There is known a V-belt type stepless transmission of this type in which an electric motor is used to move the movable flange of the main sheave, thereby adjusting the groove width. The moving driving force of the electric motor causes the movable flange to be in the direction of narrowing the width of the main sheave (top side) or widening the groove width of the main sheave (low (L〇w) side) Movement, thereby allowing adjustment of the groove width (for example, refer to Patent Document 1) ^ 129444.doc 200900609 [Patent Document 1] Japanese Patent No. 3043061 [Patent Document 2] Japanese Patent No. 2950957 [Patent Document 3] JP-A- 7-1 19804 [Disclosure] [Disclosure of the Invention] [Problems to be Solved by the Invention] A scooter type motorcycle having a mechanism for electronically controlling a V-belt type stepless speed changer does not require a rider to perform In any operation, the program (map) for vehicle speed and engine speed is automatically changed based on a pre-input program. Therefore, the rider's driving operation becomes simpler and has been made to automatically override this. The segment shifter is applied to various types of vehicles. When a vehicle equipped with such a stepless transmission runs downhill, the vehicle can slide down the downhill by inertia while the engine is stopped. In this case, right Use, respond to the car The mechanism that changes the gear ratio when it is 'when the engine is started after reaching a certain speed, the clutch can be sprayed immediately. At this time, : will occur - the possibility of the problem', that is, the actual acceleration of the ride due to the ride Between /, [the way to solve the problem] feels unpleasant to the twins. «The straddle-type vehicle of the present invention (four), the engine connected to the "European speed machine", and the control of the non-segment including mode Switching the operating member, (4). The straddle-type vehicle driving module W is set in the 忒 control device with a plurality of (four) H hai control devices executing the first: the driving mode is switched to the plural modal mode. Performing a second control: in response to I29444.doc 200900609 d, switching between the plurality of drive modes by switching the operation of the operation component, the control is performed to perform the third control: when the control (four) is set to _ when the engine has not been started Limiting the second control and suppressing switching from the determined driving mode to another driving mode. [Advantages of the Invention] According to the present invention, the control of the farm implements: the first control, at the engine start Switching the driving mode to the predetermined driving mode of the plurality of driving modes; the first - π ^ _ control, in response to the mode switching operation component, is in the plurality of Switch between the modes; and the third control, the field control device detects that the white control is finished. * When the engine is started, 'the second control is limited and the driving mode is suppressed from the other to the other.

At, the force drives the switch. Therefore, there is a month when the engine is started, the LV, π is fixed in the drive mode, and the starting line starts the car in the same driving mode, ', and fine... so that it can be immediately followed by the start (when the vehicle The driving performance after the start of the period is maintained at a constant level. In addition, when the control device detects that the engine has not been switched to the starter engine and the drive mode is still in motion mode, the control device m has a predetermined drive r-v System: Switching the drive mode to the correct plate type. In this case, for example, when the P is in the state of reaching a certain speed, the field is activated by the starter, and it is also possible to reduce the Riding the W engine and fitting the centrifugal clutch to the non-sexual 1 ' between the actual movement of the vehicle and the vehicle! The unpleasant feeling of the child, [Embodiment] Daily improvement of the rider comfort. Shi (for example) Figure 9 As shown in the figure, the no-segment change 1 - ΙΪΠ 56 ^ machine ^ includes the connection to the spindle of the rotation caused by the entrainment 9 to be connected by the engine 2 to the power output via the centrifugal clutch 6 129444.doc 200900609 To the rear wheel (drive wheel) 7 * Fo of the sub sheaves, and the winding sheave 3 and the sub-belt sheave heart 5. In addition, a groove width adjusting device: withered whole width main groove 3 of the wheel, whereby the stepless adjustment of the gear ratio.

The stepless transmission 1 described in the text may include a mechanism for changing the speed ratio in response to the speed of the vehicle when the vehicle is traveling downhill. In this case, the event may occur when the engine 2 is started in a state in which a certain speed has been reached, based on the pre-purification; the program of the vehicle speed and the engine speed (mapping) is quickly performed. When such an event occurs, there is a possibility that the rotational speed of the secondary sheave 4 located downstream of the engine 2 will also increase, so that the centrifugal clutch 6 is immediately sprayed: the feeling under this condition is completely different from when the normal start The sense m' in the case where the clutch is incompetent may feel unpleasant due to the inconsistency between the operation of the rider and the actual vehicle movement. The inventors of the present invention have found that 'the ambience of the visible centrifugal clutch 6 feels an unpleasant feeling due to the non-synchronization between the operation of the ride and the movement of the vehicle, and has been designed to reduce the ringing The mechanism of the unpleasant feeling felt when the centrifugal clutch is felt, thereby achieving the present invention. In the following, embodiments of the invention will be described with reference to the drawings. In the following figures, the same or similar reference numerals are used to indicate the same or similar operations.

The structural components are omitted, and the description of the same structural components will be omitted. The present invention is not limited to the following embodiments. X Fig. 1 shows a side structure of a straddle type vehicle 1 according to an embodiment of the present invention. Fig. 2 is a block diagram for explaining the configuration of the control device 10 and its surroundings mounted to the straddle type vehicle 1 according to the embodiment. 129444.doc 200900609 As shown in FIG. 2, the straddle type vehicle 1 according to the embodiment includes a drive source (engine) 20 having an output controlled in response to the accelerator operating portion 25 operated by the rider, and is connected to the engine. 2〇's stepless speed changer 3〇, and electronically controlled stepless speed changer 3 0 control unit 1 〇. Note that in the embodiment, the engine 20 and the stepless transmission 30 form a power unit 8A. The straddle type vehicle 100 shown in Fig. 1 is a one-speed kedda type motorcycle, and the driving force generated by the engine 20 is transmitted to the rear wheel (drive wheel) 40 via the stepless speed changer 3''. In the case of a motorcycle, the accelerator operated part 25 operated by the rider is an accelerator or accelerator handle attached to the handle. The stepless speed changer 30 according to the embodiment has a structure in which the main sheave 32 is coupled to a main shaft 31 (for example, a crank shaft) that is rotated by the engine 20, and the sub sheave 34 is connected to the centrifugal clutch 5 and The speed reduction mechanism 5 输出 outputs power to the counter shaft 35 of the rear wheel 40 (drive wheel), and the v-belt 33 is wound around the main sheave 32 and the auxiliary sheave 34. In addition, the gear ratio is controlled steplessly and steplessly by changing the groove width of each sheave. The main sheave 32 and the auxiliary sheave 34 are constructed by fixing flanges (32a, 34a) and movable flanges (10), 34b, respectively attached to the main shaft 3'' and the countershaft 35, respectively. The movable flanges (32b, 34b) are provided such that they are movable in the direction of the main shaft 31 and in the direction of the i-axis, respectively. The idea is that the fixing flange can also be referred to as a fixed sheave and the movable flange can also be referred to as a movable sheave. The movable flange 34b of the sub-groove 34 is advanced in the direction in which the groove width is narrowed by the groove width adjusting mechanism. The groove width adjusting mechanism of this embodiment is formed by a spring (not shown) attached to the movable flange 34b and a torque cam (not shown) provided in a portion of the movable flange 34b. 129444.doc 10 200900609 On the other hand, the main sheave 32 is adjusted by controlling the movement of the movable flange 32b of the main sheave 32 (so that it can be slidably moved in the direction of the main shaft 31) using the actuator 60. Slot width. The rotation of the actuator 6 can cause the movable flange 32b to narrow the groove width of the main sheave 32 (i.e., to the τ〇ρ side) and widen the groove width (i.e., to L) 〇w side) move in. Thereby, it is possible to freely adjust the groove width.

In this embodiment, the actuator 6G is an electric motor. The output of the electric motor 6 is controlled by the power supplied to the electric motor 60. That is, the electric motor 6 turns the electric energy corresponding to the electric motor 6 to mechanical energy, and outputs the mechanical energy to the movable flange 32b, thereby moving the movable flange 32b. The actuator 6 that adjusts the groove width of the main sheave 32 is electrically connected to a control device (shift control device) U). The control device 10 is constructed by an electronic control unit (ecu; electronic control unit). The electronic control unit (ECU) is configured by, for example, a microcomputer (Mpu). The control device 1 performs control so that it calculates a gear ratio corresponding to a vehicle operating condition (such as a vehicle speed, a throttle opening degree) based on a pre-registered control map (program), and issues a change to the no-segment 30 Command to achieve the speed ratio, ratio. The stalk finally achieves the shifting control to calculate the target value of the gear ratio based on the vehicle speed and the throttle opening: the self-reading control map (the target variable burial = the electric motor (9) and the active sheave of the main sheave) The position is such that: : the target gear ratio. The control map is stored in the control of the farmer; or the memory unit of the electrical connection device 10 can be provided outside the control split 10, and the control map can be Stored in the = 129444.doc 200900609 ^. The memory unit can be configured by, for example, a semiconductor memory (ram body 'or its analog) or a hard disk. '仏Electronically controlled as described above In the real _., the setting can be adapted according to the rider's intention; the broadcast feature is selected. The two are set in the control device 1. The plurality of driving modes of the controller 30 are controlled. Further, the control device Π) executes the first control U, the second control 12', and the third control 13. The program executes the controls. The control w is based on the preset control 11 to control the drive mode (A, hp to the complex (A)) before the engine 20 is started. The second control 12 is for responding to the operation of the mode switching operation unit 27. Control for switching between the plurality of drive modes (A, b). The third control 13 is for limiting the second control suppression from the determined drive mode (A) to another drive mode when the debt is detected to have not yet started the engine ( B) Control of the switching. Here, "determining the driving mode" is the driving mode set in the control device 1A. When the towel has a predetermined purge type. In this embodiment, " The driving mode" may also be referred to as "normal mode, or, initial mode" as appropriate. As shown in Fig. 3(a), the driving mode, that is, when used herein, the stepless shifting in this embodiment In the machine 3, the two normal modes "A" and the auxiliary mode "B" are used. Note that the drive mode " is used to indicate the shifting characteristics of the 129444.doc 200900609 machine that is set for the stepless speed change. The terminology of each method It is stated that the speeds of the drive model engines are set to low, and the normal mode "A" is to set the engine mode speed (the engine speed in the drive mode of the economy mode consumption, material, etc. is set to be higher than the normal mode, Α" in the change target area. The domain highlights the engine's speed in the mountain 1 engine and the driving mode (power mode) in turn. As shown in Figure 3(C), the normal mode "Α" and auxiliary mode, and skillful As shown in the velocity diagram, orthomorphic. In Figure 3(4), the initial batch feature (control map) of the macro in the RH replacement map (control map R(A) exhibits abnormal mode"Α, and The shifting feature (control map) set in the shifting feature of the sigh (control map, type “Β ” ”.

In this embodiment, as described above, using the control as shown in Figure 3 (4) = (R (A), R (B)) perform actual control. More specifically, (4) system mapping if: - information on the degree of opening from the individual drive mode Control, R(B)) calculates the target value of the gear ratio (target gear ratio), 129444.doc -14- 200900609 and drives the electric motor 6G to achieve the target gear ratio, thereby controlling the main sheave = the moving sheave Location. Note that the 'control map R(A) shows the normal mode "A" control mapping, and the control map R(B) shows the auxiliary mode "B" control mapping. In addition, the 'control map R(A) and The control map R(B) indicates the area bounded by the control maps (control area or). The (4) area is a line li(a) and line L1(B) indicating the relationship between the vehicle speed and the target value of the engine speed when the flow valve is fully opened, and indicates the vehicle speed and I when the throttle valve is completely closed. The target of the speed: the area around the line L2 (A) and the line L2 (b). For example, if the vehicle performs control based on the control map R(A) while in the normal mode, A", the engine speed is calculated based on the calculation of the information about the vehicle speed and the throttle opening degree. The target value. More specifically, the position of the horizontal axis in Fig. 3 is determined based on the information about the speed of the vehicle. Then, the target value of the engine speed is determined in the region of the map R(A) according to the degree of opening of the throttle valve. In this case, when the throttle opening is increased, the target value of the engine speed is increased (control to the L〇w side to increase the speed ratio), and when the throttle opening degree is decreased, the target value of the engine speed is decreased ( Controlling to the TOP side to reduce the gear ratio) 'To thereby achieve smooth acceleration and deceleration. When repeatedly performing the calculation based on the information about the vehicle speed and the degree of opening of the throttle that changes with time as described above, the control device 0 calculates the target value of the engine speed 'by thereby controlling the gear ratio of the stepless transmission 30. In the stepless transmission 30 as described above, when the gear ratio reaches or exceeds a certain value, the clutch tends to In the engagement, and the rotation speed of the auxiliary sheave increases. Suppose that if the target value of the engine speed is set such that the gear ratio exceeds the value of the engagement of the clutch 129444.doc -15-200900609, the target value of the engine speed is further set to The τ〇ρ side will reduce the abrupt sensation felt when the engine brake is applied immediately after the clutch is engaged. As seen from the comparison of the control map R(A) and the control map R(B) from the example in the figure, The control map R(A) is set such that the speed ratio in the shift comparison control map R(B) is small (to the τ〇ρ side). Therefore, the control based on the control map R(4) is more effectively reduced when the engine brake is applied. : The feeling of mutation to.

Note that in this embodiment, the normal mode "Α" is set to the initial mode. However, the normal mode "Α" can be set to the other drive mode of the plurality of drive modes as long as it is a drive mode in which the gear ratio is set to decrease (to the tens (10) side). The number of configurable drive modes is not limited to one and three or more drive modes can be dispensed with in the stepless speed changer. For example, 'the gear ratio can be set to be lower than the normal mode ", the underspeed ratio is close to the third drive mode of the TOP side' and the third drive mode is used as the initial mode. Further, this embodiment uses a method of switching between drive modes in which the drive mode is switched by switching the control map. However, the method of switching between drive modes is not limited to group A, and is here. For example, the shifting feature can be changed by multiplying by multiplying by - multiplying the conversion factor by switching the control map. More /, body port ' can shift the target calculated from the determination control map to the determined conversion factor (for example, 135), thereby making it possible to switch to the shifting characteristic of the shift ratio (made to the LQW side) (π In the downshift mode, in this case, the number of downshift modes can be set to one by 趑h + J 0 J. A configuration can be adopted, which is divided by 6 /, τ § and two or more low speeds Right mode, 129444.doc -16- 200900609 == Quickly in order to respond to the rider's button operation ("multi-speed downshift handle") and sequentially increase the gear ratio (switched to l〇w side). Note that It will be true that the conversion factor is stored in the form of a factor map in a memory unit provided inside or outside the control device. A description of the method of switching between drive modes - an example of another, a gentleman in Figure 4 It can be shown that the switching between the driving modes can be performed by the combination of the switching of the driving mode = based on the control map and the switching of the low-speed mode j which is multiplied by the multiplication of the conversion factor. Example ^ ' can respond to the rider operating mode (four) operation The component 27 is sequentially switched between the three drive modes (i.e., the normal mode "A, · the auxiliary mode & ·," and the auxiliary 11 mode C) (see arrow U in Fig. 4). In addition, adopting "Configuration, you can shift each of these drive modes to a low-speed caster state (see arrow 74 in Figure 4). Even in this case, it is possible to Before starting the engine, the driving mode is fixed in the normal mode "Α,, (i.e., 'the driving mode set to have the minimum gear ratio (to the τ〇ρ side)) to suppress the unpleasant feeling when the clutch is engaged. Now, Referring back to Fig. 2, the configuration of an embodiment of the present invention, specifically, the control performed by the control device of the stepless transmission will be described in detail. The straddle type vehicle 100 includes an engine for detecting the speed of the engine 20. The speed sensor 22. The control device 1 detects whether the engine 2 has not been started based on whether the engine speed detected by the engine speed sensor 22 is 〇. In this embodiment, the detection engine 20 is used. Speed engine speed sensor 22 Connected to the control device 丨〇, and output the engine speed signal to the control device 1. When the control device 1 detects that the engine 20 has not been started 129444.doc 200900609 via the engine speed sensor 22, it issues a mode switching suppression command. More specifically, the mode switching suppression command is issued based on the engine speed signal output from the engine speed sensor 22 (more specifically, the engine speed signal indicating the engine speed is " 0". Note that mode switching suppression The command is not limited to the engine speed signal output from the engine speed sensor 22. A configuration may be employed in which other information indicating that the engine has not been started is based (eg, based on the main switch, turning on to determine whether ignition has been performed or Injection) Issues a mode switching suppression command. Additionally, the wheel speed sensor 52 is electrically coupled to the control device 10 for detecting the speed of the rear wheel 40. The rear wheel speed sensor 52 is disposed near the rear wheel 4, and outputs a rear wheel speed signal to the control unit 丨〇. The vehicle speed can be obtained from the rear wheel speed signal. Further, a mode switching switch (mode switching SW) serving as the mode switching operation section 27 is electrically connected to the (4) device 1G. Switching between the plurality of drive modes is performed by the rider turning on the mode switch. The mode switch can be, for example, a mode switch button having a button shape. Further, a sheave position detecting means 29 for detecting the flange position of the movable flange 32b of the main sheave 32 is connected to the control means 1G. The sheave position detecting means 29 can output information on the position of the movable flange (movable flange position signal) to the control device 10. The control unit 1 controls the electric motor 6〇 using a message regarding the position of the flange (the movable flange position signal). Note that various signals (for example, throttle opening signal, sub-groove rotation speed signal =, etc.) and rear wheel speed signals, engine speed signals, and movable flange position signals are input to the control unit 丨0. Next, the control 129444.doc -18-200900609 method of the control device 10 will be described with reference to the flowchart in Fig. 5. First, control the clothing 10 in the engine 2 〇 start a drive mode (A, B) has been determined in advance: Equation (A) (first control). In this embodiment, when the main switch (the main power of the vehicle 100, the 10,000 unit) is "on", 'S20, and will drive ...t), the control device 1 proceeds to the step, A,,) .

When determined When there is a drive mode switching request, it is determined at step S4° whether or not (4) engine 20 has been started. In this case, brother::: Engine 2 has not been started yet, the process proceeds to step 2, mode setting is rejected. Only the request is changed, and the drive mode is confirmed and the drive is allowed to be in the initial mode (normal mode "A") (step S70). : face 'when it is determined at step S40 that the introduction-to-step has been started, at step S6 In the acceptance mode cut: 仃 From the initial mode (normal mode) A") to another mode: and confirm and set the drive mode (step s^) B) in this state (positive 'often: ! 2:) = The drive mode of the engine can be fixed in the initial mode main switch昧Note that, in the example described herein, when turned ,, ,,, _ mode shift to the n-initial modulus Seoul Mod ^ change to the initial mode based capitalization sufficient. Therefore, with = 129444.doc • 19. 200900609 The timing of the initial mode shift is not limited to, when the "main switch is turned on. For example, 'the following is acceptable: adopt a configuration, in which the engine is turned off The shift to the initial mode is performed so that the shift to the initial mode has been completed the next time the "main" switch is turned "on". Alternatively, the following is also acceptable: adopt a set of gears that are executed to the initial mode when the "off" main switch is executed, so that when the next "on" main switch is changed to the main switch, 6 is completed. Shift to the initial mode. Next, another embodiment of the present invention will be described with reference to FIG. This embodiment differs from the embodiment described above in that the slot change to the initial mode is not performed before the engine is activated, and is executed after the engine is started. Correspondingly, the same or similar structural components as those of the straddle-type vehicle 100 are denoted by the same or similar reference numerals, and repeated description of the same structural components. In the example, the control device 10 detects that the engine 2 has just started the drive mode and has not yet switched to the pre-determined drive mode (4) among the plurality of drive modes (A, B). The control device 1 switches the drive mode to the determined drive mode (A) (fourth control 14). In this embodiment, the control device 1G is configured such that it detects the state of the just-started engine 20, and the control device (7) can perform control based on the (d) result to drive the mode from the other-drive mode (auxiliary mode &quot ; ") Switch to the initial (normal mode T). That is, it is permitted to switch the drive before the engine is started: but the drive mode is shifted to the initial mode according to the timing of the engine start. Even under the configuration described above, it is possible to start the vehicle in the initial (normal mode "A"), which will change after the engine is started: 129444.doc -20- 200900609 is set to decrease (to the TOP side). Thus, it is possible to reduce the unpleasant feeling caused by the non-synchronization between the operation of the rider and the actual movement of the vehicle. Note that in this embodiment, the control device 10 is based on the speed of the engine 20. Whether it has been increased from 0 to detect whether or not the engine 2 has just been started. That is, the control device 1 can detect the departure of the just-started engine 2 via the engine speed sensor 22. More specifically, the control device 1〇 Perform the following control: switch the drive mode from the other drive mode to the initial mode (normal mode) A" in response to the indicated engine speed signal from the increased engine speed signal. Next, a control method of the control device 10 will be described. First, at step S100, "ON" the main switch (when the vehicle field is in step 1 (the main power source of the vehicle 100), the routine proceeds = S2D0: in step S2.., control device i. determines whether it has been: Interval (in this embodiment, the determination at step S200 is repeatedly performed every 0.05 seconds (e.g., 5 〇 =) until it is determined that (4) the engine has determined that the engine has been started at step S200, The control device 10 determines in step = whether the boat mode is a different mode than 槿 =. When - determines the current mode of the initial mode (normal mode, Α", the routine proceeds to 〇 ' and maintains the initial Mode (normal mode ^ and set it to the initial mode (normal mode "Α"). It is confirmed that the 4-way mode is another aspect - when it is determined at step S300 that the current: start mode (normal mode "A") drive mode ( := At the time of execution, switch from the other mode ("Auxiliary mode" Β") to the initial mode (normal 129444.doc 21 200900609 mode "A") (step S4〇〇), 1 confirm the drive mode And set it to the initial mode (normal mode, A ") (Step S5 〇〇). In the configuration described above, even after the "Connect" main switch, the drive mode is switched to a drive mode different from the initial mode (normal mode "a") It is possible to switch the drive mode to the initial mode without fail immediately after the engine is started. Further, the determination as to whether the engine has been started at step S200 is repeatedly executed at a very short interval (for example, 50 ms). Therefore, even after the engine is started The switching drive mode 'does not affect the actual change of the gear ratio. The invention is not limited to the embodiments described above. For example, the structure of the 'stepless transmission 3' is not limited to the one described in the embodiment described above.
