Description

  The present invention relates to an internal combustion engine control device, and more particularly to an internal combustion engine control device mounted on a straddle-type vehicle that transmits engine driving force to driving wheels via a clutch to which an operating force is given by hydraulic pressure.

  Generally, in a vehicle equipped with a manual transmission, a driving force transmitted from an engine to driving wheels is adjusted by operating a clutch. When starting such a vehicle, in order to prevent engine stall, the driver needs to gradually connect the clutch from the disengaged state to the half-clutch state and open the throttle valve according to the operation of the clutch. There is. However, this operation is very likely to cause an engine stall depending on the driver's skill level and engine characteristics, and the driver needs to be accustomed to start the vehicle smoothly without engine stall. is there.

  From such a background, Patent Document 1 relates to a vehicle start control device, and in order to prevent an engine stall from occurring while the vehicle is starting, it is determined whether the clutch is engaged or not, and the clutch is engaged. A start control device is disclosed in which the throttle opening is a large throttle opening for starting.

JP 2001-73840 A

  However, according to the study of the present inventor, Patent Document 1 discloses a configuration in which the throttle opening is set to a large throttle opening for starting when the clutch is engaged. It is considered that the configuration is insufficient for reliably and easily starting the vehicle.

  Further, according to the study of the present inventor, in a saddle-ride type vehicle such as a motorcycle, the throttle valve with respect to the opening of the accelerator pedal is taken into consideration that an electronically controlled throttle is adopted. In the map data for controlling the movement of the engine, a configuration in which the throttle opening is set large in a region where the engine speed is low can be considered. However, in such a configuration, since the throttle opening can be corrected after the engine speed decreases, adjustment of the throttle opening is particularly effective when applied to a straddle-type vehicle in which the engine speed drops quickly. It is considered that there is a high possibility that engine stall will occur in time.

  The present invention has been made through the above-described studies, and is a straddle-type vehicle having a drive system in which a manual transmission is combined with a hydraulically operated clutch and the driving force of an engine is transmitted to drive wheels through these in order. An object of the present invention is to provide an internal combustion engine control device capable of reliably and easily starting.

  In order to achieve the above object, the present invention is mounted on a straddle-type vehicle that transmits the driving force of an engine to driving wheels via a clutch in which an operating force is given by hydraulic pressure, and changes the throttle opening of the engine. In the internal combustion engine control device having a control unit for controlling the throttle opening by controlling the driving of the motor according to the accelerator opening of the engine, the control unit has a predetermined speed of the straddle-type vehicle. The engagement degree of the clutch obtained from the output of a hydraulic pressure sensor that is linearly output according to the hydraulic pressure that gives the operating force to the clutch at a speed equal to or lower than a speed is equal to or higher than a predetermined level at which the saddle riding type vehicle can start, In addition, when it is determined that the braking state of the straddle-type vehicle is a predetermined braking state in which the straddle-type vehicle can start, the throttle opening increases as the connection degree increases. A first aspect is to calculate a first corrected opening that increases the value as a corrected throttle opening, and to control the drive of the motor according to a target throttle opening calculated based on the corrected throttle opening; To do.

  In addition to the first aspect, the present invention provides the throttle opening when the control unit determines that the engine speed has decreased when the first correction opening is calculated. And calculating the sum of the first correction opening and the second correction opening as the correction throttle opening is a second aspect. .

  According to the present invention, in addition to the first or second aspect, the control unit calculates the target throttle opening calculated based on the accelerator opening, based on the corrected throttle opening. If it is determined that the opening is exceeded, a third aspect is to control the driving of the motor according to the target throttle opening calculated based on the accelerator opening.

  Further, in addition to any one of the first to third aspects, the present invention provides the motor of the motor when it is determined that the connection degree of the clutch has reached a level indicating a complete connection state. It is a fourth aspect to control the driving according to the target throttle opening calculated based on the accelerator opening.

  According to the internal combustion engine control apparatus according to the first aspect of the present invention described above, the control unit outputs linearly according to the hydraulic pressure that applies the operating force to the clutch when the speed of the straddle-type vehicle is equal to or lower than the predetermined speed. The degree of clutch connection obtained from the output of the hydraulic sensor is equal to or higher than a predetermined level at which the saddle riding type vehicle can start, and the braking state of the saddle riding type vehicle is a predetermined braking state at which the saddle riding type vehicle can start. When the determination is made, the greater the degree of connection, the first corrected opening that increases the throttle opening is calculated as the corrected throttle opening, and the motor drive is calculated based on the corrected throttle opening. Since it is controlled according to the degree, it is a straddle with a drive system that combines a hydraulically operated clutch with a manual transmission and transmits the engine driving force to the drive wheels through these in turn. In the vehicle, it can be reliably and easily start the straddle-type vehicle.

  Further, according to the internal combustion engine control apparatus according to the second aspect of the present invention, when the control unit determines that the engine speed has decreased when the first correction opening degree is calculated, the throttle opening is started. The second correction opening for increasing the degree is further calculated, and the sum of the first correction opening and the second correction opening is calculated as the correction throttle opening. The start can be performed more reliably and easily.

  Further, according to the internal combustion engine control apparatus according to the third aspect of the present invention, the control unit calculates the target throttle opening calculated based on the corrected throttle opening by the target throttle opening calculated based on the accelerator opening. When it is determined that the motor is exceeded, the motor drive is controlled according to the target throttle opening calculated based on the accelerator opening, so that the saddle type vehicle reflects the operation of the accelerator operating member such as an accelerator grip. Can be started.

  Further, according to the internal combustion engine control apparatus according to the fourth aspect of the present invention, when the control unit determines that the degree of clutch engagement has reached a level indicating the complete connection state, the driving of the motor is stopped. Since the control is performed according to the target throttle opening calculated based on the degree, the straddle-type vehicle can be started more appropriately.

[Configuration of saddle riding type vehicle]
First, with reference to FIG. 1, the configuration of a saddle-ride type vehicle on which the internal combustion engine control device according to this embodiment is mounted will be described.

  FIG. 1 is a block diagram schematically showing the configuration of a straddle-type vehicle on which the internal combustion engine control device according to this embodiment is mounted.

  As shown in FIG. 1, in this embodiment, a straddle-type vehicle 1 on which an internal combustion engine control device C configured by an ECU (Electronic Control Unit) 10 is mounted includes a hydraulically operated clutch (hydraulic clutch) 2. And the vehicle which transmits the driving force of the engine which is an internal combustion engine which is not shown in figure through the manual transmission 3 connected to it to the driving wheel which is not shown in figure. Here, the hydraulic pressure generated in the master cylinder 5 in accordance with the operation amount of the clutch lever 4 is transmitted to the operating cylinder 7 via the pipe 6, and the operating cylinder 7 causes the hydraulic clutch 2 to operate in accordance with the hydraulic pressure. By engaging and disengaging, the hydraulic clutch 2 exhibits any one of a completely disconnected state, a completely connected state, and a half-clutch state. The connection state of the hydraulic clutch 2 is determined by an ECU (Electronic Control Unit) 10 that controls the operation of the entire saddle riding type vehicle 1 based on the output of the hydraulic sensor 21.

  The complete cutoff state means a disconnected state in which the rotation of the output shaft on the engine side is not transmitted to the drive shaft on the drive wheel side at all. The completely connected state means a connected state in which the rotation of the output shaft on the engine side is completely transmitted to the drive shaft on the drive wheel side. The half-clutch state is a transient state between the complete disconnection state and the complete connection state, in which the rotation of the output shaft on the engine side is transmitted to the drive shaft on the drive wheel side but is not completely transmitted. Means.

[Configuration of internal combustion engine controller]
Next, the configuration of the internal combustion engine control device C in the present embodiment will be described with reference to FIG.

  FIG. 2 is a block diagram showing a configuration of the internal combustion engine control apparatus C in the present embodiment.

  As shown in FIG. 1, the internal combustion engine control device C in the present embodiment is configured by an ECU 10. The ECU 10 includes a clutch state detection unit 11, a control unit 12, and a motor drive circuit 13, and includes a memory (not shown) and the like, and necessary control programs, control data, and the like are stored in the memory. Each of the clutch state detection unit 11 and the control unit 12 is configured such that an arithmetic processing unit such as a CPU (Central Processing Unit) provided in the ECU 10 reads a necessary control program and control data from a memory to check an operation state of the internal combustion engine. It is shown as a functional block for control.

  Specifically, the clutch state detection unit 11 detects the state of the hydraulic clutch 2 based on an input signal from the hydraulic sensor 21 that is linearly output according to the hydraulic pressure in the pipe 6. Here, the signal output from the hydraulic pressure sensor 21 to the clutch state detection unit 11 is an electric signal having a hydraulic pressure / voltage characteristic that exhibits a voltage value that changes linearly with respect to the hydraulic pressure value in the pipe 6. . The clutch state detection unit 11 inputs an electric signal according to the state of the hydraulic clutch 2 detected in this way to the control unit 12.

  Here, the control unit 12 uses the input signals from the clutch state detection unit 11, the vehicle speed sensor 22, the throttle position sensor 23, the accelerator opening sensor 24, the crank angle sensor 25, and the brake sensor 26 to control the throttle motor 27. The engine output is controlled by adjusting the throttle valve opening (throttle opening) of the engine by driving, that is, the actual throttle opening which is the actual throttle opening. The engine output control of the control unit 12 includes temporary output control according to the degree of connection of the hydraulic clutch 2 so that the start of the straddle-type vehicle is ensured and easy. The control unit 12 inputs a control signal for adjusting the throttle opening in this way to the motor drive circuit 13. Here, the vehicle speed sensor 22 inputs an electric signal according to the speed (vehicle speed) of the saddle riding type vehicle. The throttle position sensor 23 inputs an electric signal corresponding to the throttle opening of the engine. The accelerator opening sensor 24 inputs an electric signal corresponding to an operation amount (accelerator opening) of an accelerator operation member such as an accelerator grip of a saddle-ride type vehicle. The crank angle sensor 25 inputs an electric signal corresponding to the crank angle (crankshaft rotation angle) of the engine. The brake sensor 26 inputs an electric signal corresponding to the operation amount of a braking operation member such as a brake lever of the saddle riding type vehicle.

  The motor drive circuit 13 controls the throttle opening by driving the throttle motor 27 in accordance with a control signal from the control unit 12.

  The internal combustion engine control apparatus C having the above-described configuration makes it possible to start the saddle type vehicle particularly reliably and easily by executing the throttle opening increase correction process described below. Hereinafter, the operation of the internal combustion engine controller C when executing the throttle opening increase correction process will be described in detail with reference to FIGS. 3 and 4 as well.

[Throttle opening increase correction processing]
FIG. 3 is a flowchart showing the flow of the throttle opening increase correction process by the internal combustion engine controller C according to this embodiment. FIG. 4A is a time chart as an example showing a time-series change of the throttle opening and the like in the throttle opening increase correction process by the internal combustion engine control apparatus C in the present embodiment, and FIG. These are the time charts as another example which shows time-sequential changes, such as throttle opening, in the throttle opening increase correction process by the internal combustion engine control device C in the present embodiment.

  The flowchart shown in FIG. 3 starts at the timing when the ignition switch of the saddle riding type vehicle is turned on and the internal combustion engine control device C is activated, and the throttle opening increase correction process proceeds to the process of step S1. The throttle opening increase correction process is repeatedly executed every predetermined control cycle while the internal combustion engine control device C is activated.

  In the process of step S1, the control unit 12 determines whether or not the engine is in a stopped state (an engine stall state). Specifically, the control unit 12 determines whether or not the engine speed is 0 based on an input signal from the crank angle sensor 25. As a result of the determination, when the engine is in a stopped state (step S1: Yes), the control unit 12 advances the throttle opening increase correction process to the process of step S6. On the other hand, when the engine is not stopped (step S1: No), the control unit 12 advances the throttle opening increase correction process to the process of step S2.

  In the process of step S2, the control unit 12 determines whether or not the vehicle speed is equal to or lower than a predetermined vehicle speed based on an input signal from the vehicle speed sensor 22. Here, the predetermined vehicle speed is a vehicle speed corresponding to a vehicle speed at which it can be evaluated that the saddle riding type vehicle of several km / h or the like is stopped. Further, the predetermined vehicle speed is preliminarily defined and stored in the memory as a data value, and the control unit 12 reads the data value from the memory and uses it. As a result of determination, when the vehicle speed is equal to or lower than the predetermined vehicle speed (step S2: Yes), the control unit 12 advances the throttle opening increase correction process to the process of step S3. On the other hand, when the vehicle speed is not less than the predetermined vehicle speed (step S2: No), the control unit 12 advances the throttle opening increase correction process to the process of step S6.

  In the process of step S3, the clutch state detection unit 11 determines whether or not the degree of connection of the hydraulic clutch 2 is a predetermined level at which the saddle riding type vehicle can start based on the output value (voltage value) of the hydraulic sensor 21. To do. Here, the predetermined level at which the degree of clutch engagement can start the saddle riding type vehicle is such that the hydraulic clutch 2 is in a so-called half-clutch state and the torque of the output shaft on the engine side is applied to the drive shaft on the drive wheel side. It is a level which shows that it is the level of the connection degree transmitted with the magnitude | size which can start the riding type vehicle. The predetermined level is stored in the memory as a data value digitized in advance, and the control unit 12 reads the data value from the memory and uses it. As a result of the determination, if it is the predetermined level at which the vehicle can start (step S3: Yes), the clutch state detection unit 11 advances the throttle opening increase correction process to the process of step S4. On the other hand, when it is not the predetermined level which can start (step S3: No), the clutch state detection part 11 advances the throttle opening increase correction process to the process of step S6.

  In the process of step S4, the control unit 12 determines whether or not the braking state of the saddle riding type vehicle is a predetermined state in which the saddle riding type vehicle can start based on an input signal from the brake sensor 26. Here, the predetermined state in which the straddle-type vehicle is able to start when the straddle-type vehicle is in a braking state is a state in which the operation amount of the braking operation member is large enough to start the straddle-type vehicle. In the predetermined state, the operation amount of the braking operation member that can start the straddle-type vehicle is stored in advance as a data value in the memory, and the control unit 12 reads the data value from the memory and uses it. If it is determined that the vehicle is ready to start (step S4: Yes), the control unit 12 advances the throttle opening increase correction process to the process of step S5. On the other hand, when the vehicle is not ready to start (step S4: No), the control unit 12 advances the throttle opening increase correction process to the process of step S6.

  In the process of step S <b> 5, the control unit 12 calculates a corrected throttle opening (first corrected opening) for increasing the throttle opening as the degree of engagement of the hydraulic clutch 2 is lower, and passes the motor drive circuit 13. The throttle opening increase correction processing for controlling the throttle motor 27 according to the target throttle opening corrected based on the corrected up throttle opening is permitted. Here, the corrected throttle opening is stored in the memory in advance in the form of map data consisting of data values that increase as the degree of engagement of the hydraulic clutch 2 decreases. The data value is read out and used according to the degree of connection of the hydraulic clutch 2. Specifically, as shown in FIG. 4A, until the hydraulic pressure transmitted to the hydraulic clutch 2 drops to a predetermined value (period from time t = t1 to time t = t2), the control unit 12 The corrected throttle opening is calculated so that the value increases according to the amount of decrease in the hydraulic pressure. Then, the control unit 12 controls the throttle motor 27 through the motor drive circuit 13 according to the target throttle opening corrected based on the corrected throttle opening. Thereby, the process of step S5 is completed, and the current series of throttle opening increase correction process ends.

  Further, even when the target throttle opening is corrected by the corrected throttle opening in the process of step S5, it is determined that the engine speed has changed from maintaining or increasing to decreasing (for example, as shown in FIG. 4A). At time t = t2), the control unit 12 calculates an additional correction throttle opening (second correction opening) for increasing the throttle opening according to the decreased engine speed, and adds the corrected throttle opening and the addition. It is preferable to correct the target throttle opening based on the sum of the corrected throttle opening (for example, a period from time t = t2 to time t = 3 shown in FIG. 4A). Here, the additional correction throttle opening is stored in the memory in advance in the form of map data composed of data values that increase in accordance with the amount of decrease in the engine speed. The data value corresponding to the degree of engagement of the clutch 2 is read and used. Further, when it is determined that the engine speed once decreased due to the corrected throttle opening or the corrected throttle opening and the additional corrected throttle opening is increased again (for example, at time t = t3 shown in FIG. 4A). The control unit 12 preferably maintains the throttle opening in order to prevent an unnecessary sudden start of the saddle riding type vehicle (for example, a period from time t = t3 to time t = 4 shown in FIG. 4A). ). Further, the control unit 12 calculates, based on the accelerator opening, when it is determined that the degree of connection of the hydraulic clutch 2 has reached a level indicating a fully connected state (time t = t4 shown in FIG. 4A). It is preferable to control the drive of the throttle motor 27 according to the target throttle opening.

  Further, when it is determined that the hydraulic pressure has increased again after the hydraulic pressure transmitted to the hydraulic clutch 2 starts to decrease (for example, time t = t5 shown in FIG. 4B) (for example, FIG. 4B At time t = t6) shown in FIG. 5), it is preferable that the control unit 12 immediately terminates the throttle opening increase correction process in order to prevent an unnecessary engine jet. Further, the control unit 12 determines that the target throttle opening calculated based on the accelerator opening is corrected based on the corrected throttle opening or the corrected throttle opening and the additional corrected throttle opening in the process of step S5. In the case of exceeding the throttle opening, it is preferable to drive the throttle motor 27 according to the target throttle opening calculated based on the accelerator opening.

  In addition, since the throttle opening required for starting changes depending on the forward / backward inclination of the saddle riding type vehicle, the control unit 12 determines the target throttle according to the output value of the pitch angle sensor indicating the forward / backward inclination of the saddle riding type vehicle. The opening degree may be corrected. In addition, the control unit 12 may not be able to start even when the hydraulic clutch 2 is completely disconnected again, the brake operation member is operated, or the actual throttle opening is open to the throttle opening that should be able to start, If the vehicle cannot start even though the hydraulic clutch 2 is connected, it is preferable to end the throttle opening increase correction processing. Further, the control unit 12 may make it possible to set an upper limit value for the target throttle opening correction amount so that the saddle riding type vehicle does not accelerate due to erroneous feedback control.

  In the process of step S6, the control unit 12 prohibits execution of the throttle opening increase correction process. Thereby, the process of step S6 is completed, and the current series of throttle opening increase correction process ends.

  As is clear from the above description, in the internal combustion engine control apparatus C in the present embodiment, the control unit 12 is linear in response to the hydraulic pressure that applies the operating force to the clutch when the speed of the saddle riding type vehicle 1 is equal to or lower than a predetermined speed. The degree of engagement of the clutch 2 obtained from the output of the output hydraulic sensor 21 is equal to or higher than a predetermined level at which the saddle riding type vehicle 1 can start, and the braking state of the saddle riding type vehicle 1 is the start of the saddle riding type vehicle 1. When it is determined that the predetermined braking state is possible, the first corrected opening that increases the throttle opening as the degree of connection increases is calculated as the corrected throttle opening, and the drive of the motor 27 is changed to the corrected throttle opening. Since the control is performed according to the target throttle opening calculated on the basis of the engine speed, the engine is driven through the hydraulically operated clutch 2 and the manual transmission 3 in order. The vehicle 1 having a driving system for transmitting the force to the drive wheels, it is possible to start the straddle-type vehicle 1 reliably and easily.

  Further, in the internal combustion engine control apparatus C according to the present embodiment, when the control unit 12 determines that the engine speed has decreased when the first correction opening is calculated, the control unit 12 increases the throttle opening. 2 is further calculated, and the sum of the first correction opening and the second correction opening is calculated as the correction throttle opening, so that the start of the saddle riding type vehicle 1 is more reliably performed. And can be done easily.

  Further, in the internal combustion engine control apparatus C according to the present embodiment, when the control unit 12 determines that the target throttle opening calculated based on the accelerator opening exceeds the target throttle opening calculated based on the corrected throttle opening. Since the drive of the motor 27 is controlled according to the target throttle opening calculated based on the accelerator opening, the start of the straddle-type vehicle 1 is reflected reflecting the operation of an accelerator operating member such as an accelerator grip. It can be carried out.

  Further, in the internal combustion engine control apparatus C in the present embodiment, when the control unit 12 determines that the degree of engagement of the clutch 2 has reached a level indicating a fully connected state, the motor 27 is driven based on the accelerator opening. Thus, the saddle riding type vehicle 1 can be started more appropriately.

  In the present invention, the type, shape, arrangement, number, and the like of the members are not limited to the above-described embodiment, and the gist of the invention is appropriately replaced such that the constituent elements are appropriately replaced with those having the same operational effects. Of course, it can be changed as appropriate without departing from the scope.

  As described above, the present invention ensures the start of a straddle-type vehicle having a drive system that combines a hydraulically operated clutch with a manual transmission and transmits the driving force of the engine to the drive wheels through them in order. In addition, the internal combustion engine control device that can be easily performed can be provided, and is expected to be widely applicable to internal combustion engine control devices such as vehicles because of its general-purpose universal character.
