Description

straddled vehicle

The present invention relates to a straddled vehicle having a notification device that notifies an abnormal state.

Straddled vehicles may malfunction for some reason. A straddled vehicle refers to any vehicle in which a rider straddles a saddle. In order to encourage the rider of the straddled vehicle to recover from the abnormal state to the normal state, conventional straddled vehicles have been designed to allow the rider to recover from the abnormal state when an abnormality occurs, as described in Patent Document 1, for example. It has an informing device for informing that it is.

EP 2868512

　In some cases, it may be necessary to encourage the rider of the straddled vehicle to recover from an abnormal state to a normal state.

An object of the present invention is to provide a straddled vehicle that can facilitate recovery from an abnormal state to a normal state for the rider of the straddled vehicle.

(1) A straddled vehicle according to one embodiment of the present invention has the following configuration.
The straddled vehicle includes a power source that generates power for the straddled vehicle to run, a notification device that notifies a rider of the straddled vehicle, and a control device that controls the power source and the notification device. When the straddled vehicle transitions from the normal state to the first abnormal state and is currently in the first abnormal state, the notification device prompts the rider to recover from the first abnormal state to the normal state. It has an anomaly annunciator configured to annunciate the state. The control device is configured to initiate a restricted state in which performance of the power source is restricted if the first abnormal condition continues.

According to this configuration, when the first abnormal state continues, a restricted state is started in which the performance of the power source is restricted. Therefore, it is possible to prompt the rider of the straddled vehicle to recover from the first abnormal state to the normal state more than when only the notification of the first abnormal state is performed.

In the present invention, the "restricted state in which the performance of the power source is restricted" is, for example, a state in which at least one of the rotational speed of the power source, the torque of the power source, and the output of the power source is restricted. The method of limiting the performance of the power source is not particularly limited. In the present invention, "the restricted state in which the performance of the power source is restricted" may be a state in which the performance of the power source is restricted so as to limit the vehicle speed.

In the present invention, the power source may be an engine, an electric motor, or a combination of an engine and an electric motor. A starter motor used in combination with an engine is not included in the electric motor as a power source.

In the present invention, reporting the first abnormal state means reporting that the straddled vehicle is currently in the first abnormal state. In the present invention, "notifying the rider of the first abnormal condition so as to prompt recovery from the first abnormal condition to the normal condition" means only notifying that the straddled vehicle is currently in the first abnormal condition. In addition to indicating that the straddled vehicle is currently in the first abnormal condition, it may also inform the rider of actions that the rider can take to restore the normal condition from the first abnormal condition. In the present invention, the abnormality notification unit notifies the rider of the first abnormal condition in order to prompt the rider to recover from the first abnormal condition to the normal condition.

In addition, in the present invention, the notification of the first abnormal state by the abnormality notification unit may be performed while the straddled vehicle is running. The notification of the first abnormal state by the abnormality notification unit may be performed at least one time before the power source is started, when the power source is started, when the power source is stopped, and after the power source is stopped. In this case, the notification of the first abnormal state by the abnormality notification unit may or may not be performed while the straddled vehicle is running.

In addition, in the present invention, the notification device is connected to the control device wirelessly or by wire. The notification device may be composed of, for example, a plurality of devices each connected to the control device, or may be composed of one integrated device. In the present invention, the anomaly notifying section may be composed of a plurality of devices, or may be composed of a single device. The anomaly reporting unit may be configured as a part of one device. The anomaly notification unit may be configured by a part of one device and at least one other device. The anomaly reporting unit may be configured by a part of each of the plurality of devices.

In the present invention, the first abnormal state is an abnormal state that limits the performance of the power source when the first abnormal state continues. The first abnormal state does not damage the power source or straddled vehicle, but it is desirable to restore the normal state, so it is desirable to limit the performance of the power source if the first abnormal state continues. state. The restricted condition is not initiated when the straddled vehicle is restored from the first abnormal condition to the normal condition. When the straddled vehicle recovers from the first abnormal condition to the normal condition after initiation of the restricted condition, the restricted condition is released. The first abnormal conditions include, for example, sensor abnormal conditions that affect the performance of the power source and/or the driving performance of the vehicle, conditions in which certain parts of the straddled vehicle have been modified (customized), and the like. Modification of specific parts includes replacement of specific parts and removal of specific parts. Replacement for repair is not included in modification.
The first abnormal condition in the present invention differs from the second abnormal condition as follows. The second abnormal state is an abnormal state in which performance of the power source is not restricted even if the second abnormal state continues. The second abnormal state is an abnormal state in which it is desirable to restore the normal state, but there is no need to limit the performance of the power source even if the second abnormal state continues. A second abnormal condition is an abnormal condition that does not damage the power source or straddled vehicle.
The first abnormal condition in the present invention is different from the third abnormal condition as follows. The third abnormal state is an abnormal state in which a restricted state in which the performance of the power source is restricted is initiated as soon as the straddled vehicle transitions from the normal state to the third abnormal state. The third abnormal condition is an abnormal condition in which it is necessary to immediately limit the performance of the power source because damage to the power source and/or the straddled vehicle is expected. The grace period from the transition to the first abnormal state to the start of the restricted state is longer than the grace period from the transition to the third abnormal state to the start of the restricted state. The straddled vehicle in the present invention may not assume the third abnormal condition.
The first abnormal condition in the present invention is different from the fourth abnormal condition as follows. A fourth abnormal condition is an abnormal condition in which damage to the power source and straddled vehicle is assumed, but the performance of the power source is not restricted even if the fourth abnormal condition continues. The straddled vehicle in the present invention may not assume the fourth abnormal condition.

In addition, in the present invention, the control device may determine whether the straddled vehicle has transitioned from the normal state to the first abnormal state. The controller may determine whether the straddled vehicle has transitioned from the normal state to the first abnormal state based on signals from equipment such as sensors. The device that sends a signal to the control device may be a dedicated device for detecting the first abnormal condition, or may be a device for other purposes.

(2) A straddled vehicle according to an embodiment of the present invention may have the following configuration in addition to the configuration of (1) above.
The notification device has an anomaly notification section and a different delay notification section. The delay notification unit notifies the rider of the delay from the present to the start of the restricted state so as to urge the rider to avoid the start of the restricted state when the abnormality notification unit reports the first abnormal state. Configured.

According to this configuration, when the anomaly annunciator reports the first anomaly, the delay annunciator notifies of the delay from the present to the start of the restricted state. Therefore, the rider can feel that the grace period is gradually shortened. As a result, the rider can be encouraged to recover from the first abnormal state to the normal state.

In the above configuration (2), "notify the delay from the present to the start of the restricted state" means to notify how much time there is from the present to the start of the restricted state. The grace period notified by the grace notice notification unit is not limited to the grace period specified by the numerical value indicating the time. In the above configuration (2), when the straddled vehicle transitions from the normal state to the first abnormal state, the control device sets a grace period from the current state to the start of the restricted state, and the grace notice section sets the Notify the set grace period. In the configuration (2) above, the grace period notified by the grace notice notification unit at a certain point in time is not necessarily the same as the actual grace period. That is, the delay from the present time to the start of the restricted state notified by the delay notification unit at a certain point in time is not necessarily the same as the actual delay from the present time to the start of the restricted state. Whether or not the grace period notified by the grace notice notification unit is the same as the actual grace period is unknown when the restricted state is started or until just before the restricted state is started. The grace period notified by the grace notice notification unit may be shorter than the actual grace period. Also, the grace period notified by the grace notice notification unit may be longer than the actual grace period. In the configuration of (2) above, the number of types of delays notified by the delay notification unit may be one or plural. One or more types of delays may be notified during the period from the transition to the first abnormal state to the start of the restricted state. One or more types of grace period may be notified at a certain time.

In the above configuration (2), "informing the rider of the delay so as to urge the rider to avoid starting the restricted state" means to instruct the rider to recover from the first abnormal state to the normal state. It is to notify the grace so as to encourage avoidance of the onset of the restricted state by taking action. "Notify the rider of the grace so as to urge the rider to avoid starting the restricted state" may be to notify only the grace, and in addition to the grace, the rider It is also possible to notify the action that can be taken by the Actions that the rider can take to avoid the start of the restricted state are the same actions that the rider can take to recover from the first abnormal state to the normal state. In the configuration of (2) above, the grace period notification unit notifies the rider of the grace period in order to urge the rider to avoid starting the restricted state.

It should be noted that, in the configuration (2) above, that the delayed forecast notification unit is different from the abnormality notification unit means that the configuration of the delayed forecast notification unit is different from the configuration of the abnormality notification unit. In the configuration (2) above, the delayed notification by the delayed notification section is different from the notification of the first abnormal state by the abnormal notification section.

In the configuration of (2) above, the notification of the delay by the delay notification unit may be performed while the straddled vehicle is running. The delay notification by the delay notification unit may be performed at least one time before the power source is started, when the power source is started, when the power source is stopped, and after the power source is stopped. In this case, the delay notification by the delay notification unit may or may not be performed while the straddled vehicle is running. The "notification device" in the above configuration (2) is the "notification device Equivalent to The "abnormality reporting unit" in the configuration (2) above corresponds to the "abnormality reporting unit" in the first invention described in the basic application.

(3) A straddled vehicle according to an embodiment of the present invention may have the following configuration in addition to the configuration of (2) above.
The delay notification unit is configured to notify at least one of the number of times the power source is started, the travel distance, and the travel time from the present to the start of the restricted state as the grace from the present to the start of the restricted state.

In the configuration of (3) above, the delay notification unit may notify the number of times the power source has been started, the traveled distance, and the traveled time from the present until the start of the restricted state as a grace from the present until the start of the restricted state. good. These three delays may be notified during the period from the transition to the first abnormal state to the start of the restricted state. At some point in time, the three grace periods may be announced simultaneously. In the configuration of (3) above, the delay notification unit selects only one of the number of times the power source is started, the traveled distance, and the traveled time from the present until the start of the restricted state as the grace period from the present to the start of the restricted state. may be notified. In the above configuration (3), the delay notification unit notifies any two of the number of times the power source has been started, the traveled distance, and the traveled time from the present until the start of the restricted state as the grace period from the present to the start of the restricted state. You may These two delays may be the number of times the power source is started and the traveled distance. These two delays may be the number of times the power source is started and the running time. The two allowances may be distance traveled and travel time. When the delay notified by the delay notification unit is the number of times of starting, a long delay means that the number of times of starting as the delay is large.

(4) A straddled vehicle according to an embodiment of the present invention may have the following configuration in addition to the configuration of (3) above.
The delay notification unit is configured to be able to notify all of the number of times the power source has been started, the traveled distance, and the traveled time as a grace period from the present to the start of the restricted state. The control device is configured to change the type and the number or type of delay notified by the delay notification unit according to the number of times the power source has been started, the travel distance, and the travel time from the transition to the first abnormal state to the present. be done.

According to this configuration, the control device changes the type of delay notified by the delay notification unit according to the number of times the power source has been started, the travel distance, and the travel time from the transition to the first abnormal state to the present. For this reason, for example, the control device can cause the grace period notification unit to notify the grace period that is estimated to be the shortest among the number of times the power source is started, the travel distance, and the travel time. In addition, the control device may change the number of delays notified by the delay notification unit according to the number of times the power source has been started, the travel distance, and the travel time from the transition to the first abnormal state to the present. In this case, for example, the control device can reduce the number of grace periods to be notified as the elapsed time after the transition to the first abnormal state increases. For this reason, for example, at the time of transition to the first abnormal state, the control device causes the delay notification section to notify the three delays, and when the elapsed time after the transition to the first abnormal state becomes longer, the number of times the power source is started. , the delay estimated to be the shortest among the delays of the running distance and the running time can be notified to the delay notification unit. Therefore, by changing the type and the number or type of delay notified by the delay notification unit according to the number of times the power source has been started, the travel distance, and the travel time from the transition to the first abnormal state to the present time, the power The rider can be notified of the delay closest to the actual delay among the delays of the number of times the source has been started, the distance traveled, and the duration of the trip. As a result, the rider can be encouraged to recover from the first abnormal state to the normal state.

In the above configuration (4), the fact that the graceful forecast notification unit is configured to notify the number of times the power source has been started, the traveled distance, and the traveled time means that the graceful forecasting unit is configured to notify the number of times the power source has been and the travel time are not limited to being configured to be able to be notified at the same time. If the delay warning unit is configured to be able to report all of the number of times the power source has been started, the distance traveled, and the time traveled, the delay notice unit may detect at most one or two of the number of times the power source has been started, the distance traveled, and the travel time. It may be configured so that two delays can be notified at the same time.

In the configuration of (4) above, the type and number of grace periods to be notified or the type is changed means that the type and number of grace periods to be notified are changed, or the number of grace periods to be notified is It means that the type of grace that is reported without change is changed. When the type and number of delays to be notified are changed, the delay notification unit may be configured to simultaneously notify the number of times the power source is started, the travel distance, and the travel time as the delay. When the type and number of delays to be notified are changed, the delay notification unit may be configured to simultaneously notify up to two delays out of the number of times the power source is started, the travel distance, and the travel time. If the type of grace period to be notified is changed without changing the number of grace periods to be notified, the grace notice detecting unit will give at most one or two grace periods out of the number of times the power source has been started, the travel distance, and the travel time. It is configured so that it can be notified at the same time.

(5) A straddled vehicle according to an embodiment of the present invention may have the following configuration in addition to at least one configuration of (2) to (4) above.
The controller is configured to initiate the restricted state when the grace period reported by the grace warning section changes from a value greater than zero to zero.

It should be noted that, in the configuration of (5) above, "the time limit to be notified is zero" is not limited to the notification of a numerical value of zero. "The time limit to be notified is zero" means that the time limit information unit notifies so that the rider can understand that the time limit is zero. In the above configuration (5), "the restricted state is started when the notified grace period changes to zero" means that the timing at which the notified grace period changes to zero and the timing at which the restricted state is started are different. It is not limited to exact matching. In the above configuration (5), "when the notified delay changes from a value greater than zero to zero" is not limited to when the notified delay continuously changes from a value greater than zero to zero. There may be a period during which no notification is made by the grace period notification unit between the period in which the notified grace period is greater than zero and the period in which the notified grace period is zero. The configuration of (5) above does not limit the restricted state to always start when the grace period notified by the grace notice section changes from a value greater than zero to zero. That is, in the above configuration (5), the control device does not necessarily start the restricted state when the delay notified by the delay notification unit changes from a value greater than zero to zero.

(6) A straddled vehicle according to an embodiment of the present invention may have the following configuration in addition to at least one configuration of (1) to (5) above.
The controller is configured to initiate the restricted state when the grace period reported by the grace notice section continues to be zero.

According to this configuration, even if the control device cannot clearly specify the grace period from the present to the start of the restricted state, the grace notice section can notify the grace period.

It should be noted that, in the configuration of (6) above, "the delay to be notified is zero" is not limited to the notification of a numerical value of zero. "The time limit to be notified is zero" means that the time limit information unit notifies so that the rider can understand that the time limit is zero. The configuration of (6) above does not limit the restriction state to always start when the state in which the grace period notified by the grace notice notification unit is zero continues. The straddled vehicle having the configuration (6) above may have the configuration (5) above.

(7) A straddled vehicle according to an embodiment of the present invention may have the following configuration in addition to at least one configuration of (2) to (4) above.
The controller is configured to initiate the restricted mode if the first abnormal condition persists. The limit mode is a mode in which a limit state is started according to the vehicle speed. The delay notification unit is configured to notify the delay from the present time to the start of the limit mode when the abnormality notification unit is reporting the first abnormal state.

According to this configuration, the control device starts the limit mode when the delay notified by the delay notification unit becomes zero, and starts the limit state when the vehicle speed satisfies a predetermined condition during execution of the limit mode. The controller cannot explicitly specify the delay from now to the start of the restricted state, but it can identify the delay from now to the start of the restricted mode. By reporting the delay from the present time to the start of the restricted mode, the rider can grasp the approximate delay from the present time to the start of the restricted state. As a result, the rider can be encouraged to recover from the first abnormal state to the normal state.

In the above configuration (7), "notify the delay from the present to the start of the restricted mode" means to notify how much time there is from the present to the start of the restricted mode. The delay before starting the restricted mode notified by the delay notification unit is not limited to the delay specified by the numerical value indicating the time. In the above configuration (7), when the straddled vehicle transitions from the normal state to the first abnormal state, the control device sets a grace period from the current state to the start of the restriction mode, and the grace notice section causes the restriction device to Notify the delay until the set restriction mode starts. In the configuration of (7) above, the restricted state is started at the same time as or after the restricted mode is started. If the restricted state is started at the same time as the restricted mode is started, the delay before the start of the restricted mode notified by the delay notification unit is the same as the delay before the start of the restricted state. In this case, it can be said that the grace period notification unit notifies of the grace period until the start of the restricted state. Whether or not the delay before the start of the restricted mode notified by the delay notification unit is the same as the delay before the start of the restricted state is unknown until or immediately before the restricted state starts. be.

The annunciator is configured to announce that the straddled vehicle is currently in the restricted state if the restricted state is initiated.

According to this configuration, the rider can know that the straddled vehicle is currently in the restricted state not only from the running state of the straddled vehicle but also from the notification by the notification device. Thereby, when the straddled vehicle is in the restricted state, it is possible to prompt the rider to recover from the first abnormal state to the normal state.

(9) A straddled vehicle according to an embodiment of the present invention may have the following configuration in addition to the configuration of (8) above.
The notification device is configured to notify that the straddled vehicle is in the restricted state, and has a restriction notification section different from the abnormality notification section.

According to this configuration, the restriction notification unit, which is different from the abnormality notification unit, notifies the restricted state. Therefore, compared with the case where the abnormality notification unit notifies the restricted state, it is easier for the rider to recognize the notification of the restricted state by the notification device. As a result, the rider can be encouraged to recover from the first abnormal state to the normal state.

(10) A straddled vehicle according to an embodiment of the present invention may have the following configuration in addition to at least one of the configurations (1) to (9) above.
When the straddled vehicle transitions from the normal state to the second abnormal state and is currently in the second abnormal state, the notification device prompts the rider to recover from the second abnormal state to the normal state. configured to report status; The controller is configured not to limit performance of the power source even if the second abnormal condition continues.

According to this configuration, the control device does not limit the performance of the power source even if the second abnormal state continues. Therefore, the rider can easily recognize the difference between the first abnormal state and the second abnormal state. As a result, the rider of the straddled vehicle can be encouraged to recover from the first abnormal state to the normal state.

In the configuration (10) above, the notification of the second abnormal state by the notification device may be performed while the straddled vehicle is running. The notification of the second abnormal state by the notification device may be performed at least one time before the power source is started, when the power source is started, when the power source is stopped, and after the power source is stopped. In this case, the notification of the second abnormal state by the notification device may or may not be performed while the straddled vehicle is running. The "notification device" in the above configuration (10) includes the "abnormality notification device" in the second invention described in the basic application.

(11) A straddled vehicle according to an embodiment of the present invention may have the following configuration in addition to the configuration of (10) above.
The notification device is configured to notify the second abnormal state, and has a second abnormality notification section different from the abnormality notification section. The notification of the first abnormal state by the abnormality notification unit is different from the notification of the second abnormal state by the second abnormality notification unit.

According to this configuration, the anomaly reporting section that reports the first abnormal state is different from the second anomaly reporting section that reports the second abnormal state. Moreover, the notification of the first abnormal state is different from the notification of the second abnormal state. Therefore, the rider can easily recognize the difference between the first abnormal state and the second abnormal state. As a result, the rider of the straddled vehicle can be encouraged to recover from the first abnormal state to the normal state.

In the configuration of (11) above, the anomaly notifying section being different from the second anomaly notifying section means that the configuration of the anomaly notifying section is different from the configuration of the second anomaly notifying section. In the above configuration (11), the notification of the first abnormal state is different from the notification of the second abnormal state means that the manner of notification of the first abnormal state is different from the manner of notification of the second abnormal state. The "abnormality reporting unit" in the configuration (11) above corresponds to the "first abnormality reporting unit" in the second invention described in the basic application. The "second anomaly reporting section" in the configuration (11) above corresponds to the "second anomaly reporting section" in the second invention described in the basic application.

(12) A straddled vehicle according to an embodiment of the present invention may have the following configuration in addition to the configuration of (10) above.
The anomaly notification unit is configured to notify the second abnormal state. The notification of the first abnormal state by the abnormality notification unit is different from the notification of the second abnormal state by the abnormality notification unit. The abnormality notification unit is configured so as not to simultaneously notify the first abnormal state and the second abnormal state.

According to this configuration, both the notification of the first abnormal state and the notification of the second abnormal state are performed by the abnormality notification unit. However, the notification of the first abnormal condition is different from the notification of the second abnormal condition. Therefore, the rider can recognize the difference between the first abnormal state and the second abnormal state. As a result, the rider of the straddled vehicle can be encouraged to recover from the first abnormal state to the normal state.

Note that, in the configuration (12) above, that the notification of the first abnormal state is different from the notification of the second abnormal state means that the manner of notification of the first abnormal state is different from the manner of notification of the second abnormal state. do. The configuration of (12) above is such that the "part for notifying the first abnormal state in the abnormality notification device in the second invention described in the basic application also serves as the part for notifying the second abnormal state, and the first abnormal state is notified. This corresponds to the case where the notification is different from the notification of the second abnormal state.

(13) A straddled vehicle according to an embodiment of the present invention may have the following configuration in addition to the configuration of (10) above.
The anomaly notification unit is configured to notify the second abnormal state. The notification of the first abnormal state by the abnormality notification unit is the same as the notification of the second abnormal state by the abnormality notification unit.

According to this configuration, both the notification of the first abnormal state and the notification of the second abnormal state are performed by the abnormality notification unit. Also, the notification of the first abnormal state is the same as the notification of the second abnormal state. Therefore, the configuration of the notification device and/or the control of the notification device by the control device can be simplified.

In the configuration of (13) above, the fact that the notification of the first abnormal state is the same as the notification of the second abnormal state means that the manner of notification of the first abnormal state is the same as the manner of notification of the second abnormal state. It means that there is The configuration of (13) above is such that the "part for notifying the first abnormal state in the abnormality notification device in the second invention described in the basic application also serves as the part for notifying the second abnormal state, and the first abnormal state is notified. The notification corresponds to the same case as the notification of the second abnormal state.

In the present invention, the speed change method of the transmission may or may not be a manual transmission method. The speed change method of the transmission may or may not be a full automatic transmission method. The speed change method of the transmission may or may not be a semi-automatic transmission method. In the case of the manual transmission system, the rider operates the clutch and switches the gear position. In the case of a fully automatic transmission system, gears are automatically changed according to vehicle speed, engine speed, and the like. In the case of a semi-automatic transmission system, clutch operation is automated. In the case of a semi-automatic transmission system, gear position switching may be performed by the rider's operation or may be performed automatically.

When the straddled vehicle of the present invention has an engine, the engine may be a single-cylinder engine with a single combustion chamber or a multi-cylinder engine with multiple combustion chambers. The engine fuel may be gasoline fuel or a mixture of gasoline and alcohol. The engine may be a 4-stroke engine or a 2-stroke engine. The engine may have a spark plug that ignites the air-fuel mixture in the combustion chamber. The engine may have a throttle valve that regulates the amount of air supplied to the combustion chamber. The throttle valve may be an electronically controlled throttle valve controlled by a controller or may be a mechanically controlled throttle valve. The degree of opening of the electronically controlled throttle valve is basically controlled by the controller according to the rider's operation. The degree of opening of the electronically controlled throttle valve may be controlled by the control device without being operated by the rider. The degree of opening of the mechanically controlled throttle valve is controlled by the rider's operation. If the engine is a multi-cylinder engine, a throttle valve may be provided for each combustion chamber. The engine may have a fuel injector that injects fuel into an intake passage connected to the combustion chamber.

When the engine of the straddled vehicle of the present invention is a four-stroke engine, the engine has an intake valve that opens and closes an intake port formed in the combustion chamber, and an exhaust valve that opens and closes an exhaust port formed in the combustion chamber. . The engine may have a variable valve timing mechanism that changes the opening/closing timing of the intake valves and/or the exhaust valves. The variable valve timing mechanism may be configured such that part of the open period of the intake valve and part of the open period of the exhaust valve overlap in at least a part of the operating range. The engine may not have a variable valve timing mechanism, and the opening/closing timings of the intake valve and the exhaust valve may be constant. If the variable valve timing mechanism is not provided, the engine may be configured such that a portion of the opening period of the intake valve and a portion of the opening period of the exhaust valve overlap. A period in which the valve open periods overlap is called a valve overlap period. By providing the valve overlap period, the output of the engine can be increased. In general, straddled vehicles tend to have a longer valve overlap period than automobiles. In general, the engine speed range of straddled vehicles tends to be wider than that of automobiles. Also, in general, the load range of straddled vehicles tends to be wider than that of automobiles. Thus, in general, straddled vehicles tend to have wider operating ranges than automobiles. Therefore, in general, when a straddled vehicle is provided with a variable valve timing mechanism, there tends to be more operating regions in which the valve opening periods overlap, compared to automobiles.

When the straddled vehicle of the present invention has an engine, the engine may be a pre-combustion engine having a combustion chamber including a main chamber and a pre-chamber. The engine does not have to be a pre-chamber engine. If the straddled vehicle of the present invention has an engine, the straddled vehicle may not have a forced induction device for pressurizing the air to supply the pressurized air to the combustion chamber; may have. The supercharger may be a mechanical supercharger, an electric supercharger, or a turbocharger.

FIG. 11 shows a motorcycle that is an example of straddled vehicles according to the first to seventh embodiments of the present invention.

A straddled vehicle 1 according to a first embodiment of the present invention will be described with reference to FIG. As shown in FIG. 1, the straddled vehicle 1 includes a power source 2 that generates power for the straddled vehicle 1 to run, a notification device 10 that notifies the rider of the straddled vehicle 1, a power source 2 and a notification device. and a control device 3 for controlling the device 10 . The notification device 10 has an abnormality notification section 11 and a delayed prediction notification section 12 different from the abnormality notification section 11 . When the straddled vehicle 1 transitions from the normal state to the first abnormal state and is currently in the first abnormal state, the abnormality notification unit 11 prompts the rider to recover from the first abnormal state to the normal state. It is configured to notify the first abnormal condition. The control device 3 is configured to start a restricted state in which performance of the power source 2 is restricted when the first abnormal state continues. The delay notification unit 12 notifies the delay from the present to the start of the restricted state so as to prompt the rider to avoid the start of the restricted state when the abnormality notification unit 11 is reporting the first abnormal state. configured as The notification device 10 may have a restriction notification unit (not shown) that notifies that the straddled vehicle 1 is currently in the restricted state when the restricted state is initiated. The restriction notification section may be different from the abnormality notification section 11 .

The notification of the first abnormal state by the abnormality notification unit 11 is notification for at least one of the rider's visual, auditory, and tactile senses. The notification of the first abnormal state by the abnormality notification unit 11 may be a combination of two or more of visual, auditory, and tactile sensations.

The visual notification as notification of the first abnormal state may be, for example, display notification, light notification, or a combination thereof. The notification of the first abnormal state by display is, for example, notification by characters, numbers, symbols, icons, or the like displayed on the screen of the display device. The notification of the first abnormal state by display may be notification by a combination of at least one of letters, numbers, symbols, and icons. The screen of the display device may be, for example, a liquid crystal screen. An icon is a mark displayed on the screen. When the notification by the abnormality notification unit 11 is only notification by display, the abnormality notification unit 11 is a specific display on the display device. The abnormality notification unit 11 may be, for example, one icon displayed on the display device. The notification of the first abnormal state by light may be, for example, notification by a lamp, or may be an instantaneous flash. The lamps may for example consist of LEDs. The ramp can be a simple shape such as a circle, or it can be a specific mark. The notification of the first abnormal state by the lamp with the specific mark also serves as the notification of the first abnormal state by the display.

The auditory notification as notification of the first abnormal state is notification by sound. If the notification by the abnormality notification unit 11 is only by sound, the abnormality notification unit 11 is a sound generator. The sound for notifying the first abnormal state may be, for example, a simple sound such as that generated by an electromagnetic buzzer, a melody, or an artificial voice.

The tactile notification as notification of the first abnormal state is notification by vibration, for example. The vibration may be the vibration of the entire straddled vehicle 1, the vibration of the grip held by the rider, or the vibration of the seat on which the rider sits. The means for generating vibration may be means dedicated to notification, or may be the brake device or the power source 2 . The vibration generated by the power source 2 may be vibration due to engine braking, for example. The vibration for notification of the first abnormal state may or may not be periodic. The vibration for notification of the first abnormal state may be continuous or intermittent multiple motions. For example, when the first abnormal state is notified only at a specific timing such as when the power source 2 is stopped, the vibration for notification of the first abnormal state may be a single movement.

The deferment notification by the deferment notification unit 12 is notification for at least one of the rider's vision and hearing. The notification of the delay by the delay notification unit 12 may be both visual and auditory.

The visual notification by the delay notification unit 12 may be, for example, display notification, light notification, or a combination thereof. Notification of delay by display is, for example, notification by characters, numbers, symbols, icons, or the like displayed on the screen of the display device. Notification of delay by display may be notification by a combination of at least one of letters, numbers, symbols, and icons. If the notification by the delayed forecast notification unit 12 is only notification by display, the delayed forecast notification unit 12 is a specific display on the display device. The grace period notification unit 12 may be, for example, a combination of letters and numbers displayed on the display device, or a combination of a bar indicating the length of the grace period, letters, and a number. Notification of delay by light is, for example, notification by a lamp. The lamps may for example consist of LEDs. The ramp can be a simple shape such as a circle, or it can be a specific mark. The notification of the delay by the lamp of the specific mark also serves as the notification of the delay by the display. For example, the blinking interval of the lamp or the blinking interval of the icon displayed on the display device may be changed according to the length of the grace period. Also, for example, the brightness of the lamp or the brightness of the icon displayed on the display device may be changed according to the length of the grace period.

The auditory notification by the delay notification unit 12 is notification by sound. If the notification by the delayed forecast notification unit 12 is only a notification by sound, the delayed forecast notification unit 12 is a sound generating device. The notification sound may be, for example, a simple sound generated by an electromagnetic buzzer, a melody, or an artificial sound. For example, a grace period may be announced by an artificial voice. Also, for example, the type of sound may be changed according to the length of the grace period.

In the first embodiment, the notification of the first abnormal state by the abnormality notification unit 11 is different from the notification by the delay notification unit 12 . For example, when the notification of the first abnormal state includes visual notification, the delayed notification may include visual notification and may include auditory notification. When the notification of the first abnormal state includes an auditory notification, the delay notification may include a visual notification and may include an auditory notification. When the notification of the first abnormal state includes tactile notification, the delay notification may include visual notification and may include auditory notification.

For example, when the notification of the first abnormal state includes notification by display, the notification of delay may include notification by display, notification by light, and notification by sound. When the notification of the first abnormal state includes notification by light, the notification of delay may include notification by display, notification by light, or notification by sound. When the notification of the first abnormal state includes notification by sound, notification of delay may include notification by display, notification by light, and notification by sound. When notification of the first abnormal state includes notification by vibration, notification of delay may include notification by display, notification by light, or notification by sound.

For example, if the anomaly notification unit 11 includes a specific display on the display device, the delay notification unit 12 may include a specific display on the display device, a lamp, or a sound generator. However, when the delayed forecast notification unit 12 is a specific display on the display device, the display as the abnormality notification unit 11 and the display as the delayed forecast notification unit 12 are different. When the abnormality notification unit 11 includes a lamp, the delay notification unit 12 may include a specific display on a display device, a lamp, or a sound generator. However, if the delay warning section 12 is only a lamp, the lamp serving as the abnormality reporting section 11 and the lamp serving as the delay prediction section 12 are different. When the abnormality notification unit 11 includes a sound generator, the delay notification unit 12 may include a specific display on a display device, a lamp, or a sound generator. However, if the delayed forecast notification unit 12 is only a sound generator, the sound generator as the abnormality notification unit 11 and the delayed forecast notification unit 12 are different.

Next, straddled vehicles 1 according to second to fourth embodiments of the present invention will be described. The straddled vehicle 1 of the second to fourth embodiments has the configuration of the straddled vehicle 1 of the first embodiment shown in FIG. In the second embodiment, the control device 3 starts the restricted state when the delay notified by the delay notification unit 12 continues to be zero. In the second embodiment, the control device 3 may start the restricted state when the delay notified by the delay notification unit 12 changes from a value greater than zero to zero. In a third embodiment, the control device 3 is configured to initiate a restricted mode if the first abnormal condition persists. The limit mode is a mode in which a limit state is started according to the vehicle speed. In the third embodiment, the delay notification unit 12 is configured to notify the delay from the present to the start of the restriction mode when the abnormality notification unit 11 is reporting the first abnormal state. The fourth embodiment differs from both the second and third embodiments. In the fourth embodiment, the control device 3 starts the restricted state when the delay notified by the delay notification unit 12 changes from a value greater than zero to zero.

Next, specific examples 1 to 9 of the first embodiment will be described with reference to FIGS. 2 to 8. FIG. DC in FIGS. 2 to 8 means driving cycle. The driving cycle is a period from when the power source 2 is started to when it is stopped. The vertical axis of the DC graph represents the vehicle speed or the rotational speed of the power source 2 . 2 to 8 show the number of times the power source 2 is started after transitioning to the first abnormal state. 2 to 8 show at least one of the traveled distance and the traveled time after the transition to the first abnormal state. In FIGS. 2 to 8, the period during which the abnormality notification unit 11 notifies the first abnormal state, the period during which the delay notification unit 12 notifies the delay, and the period during which the straddled vehicle 1 is in the restricted state are indicated by arrows. ing. In FIGS. 5 and 8, arrows indicate periods during which the restricted mode is executed.

FIG. 2 shows specific example 1 of the first embodiment. Specific example 1 is also a specific example of the fourth embodiment. In specific example 1, when the abnormality notification unit 11 is notifying the first abnormal state, the delay notification unit 12 sets the delay from now until the start of the restricted state as a delay until the start of the restricted state. to notify the number of times the engine has been started. When the straddled vehicle 1 transitions from the normal state to the first abnormal state, the number of starts as a grace period notified by the grace notice section 12 is 10 times. In Specific Example 1, the timing at which the restricted state is started is set based on the number of times the power source 2 has been started after transitioning to the first abnormal state and the driving state of the power source 2 . Note that "based on the driving state of the power source 2" means based on whether or not the power source 2 is started. The meaning of "based on the driving state of the power source 2" in the following description is the same. In Specific Example 1, the restricted state is started when the number of times the power source 2 is started after transitioning to the first abnormal state reaches 10 and when the power source 2 is started.

It should be noted that, as a modified example of the specific example 1, the number of start-up times as grace may or may not include the time of start-up when the restricted state is started as one time. In other words, the number of times of start-up as a delay notified by the delay notification unit 12 when the straddled vehicle 1 transitions from the normal state to the first abnormal state may be nine.

FIG. 3 shows a specific example 2 of the first embodiment. Specific example 2 is also a specific example of the fourth embodiment. In specific example 2, when the abnormality notification unit 11 is notifying the first abnormal state, the delay notification unit 12 sets the delay from now until the start of the restricted state as a delay until the start of the restricted state. to report the mileage of the The graceful mileage notified by the graceful warning section 12 when the straddled vehicle 1 transitions from the normal state to the first abnormal state is 500 miles. In specific example 2, the timing to start the restricted state is set based only on the distance traveled after the transition to the first abnormal state. The restricted state is initiated when the traveled distance reaches 500 miles after transitioning to the first abnormal state.

As a modification of Example 2, the timing at which the restricted state is started is based on the travel time after the transition to the first abnormal state instead of the travel distance after the transition to the first abnormal state. may be set. In this case, the delay notified by the delay notification unit 12 is the running time.

FIG. 4 shows a specific example 3 of the first embodiment. Specific example 3 is also a specific example of the second embodiment. In specific example 3, when the abnormality notification unit 11 is notifying the first abnormal state, the delay notification unit 12 sets the delay from now until the start of the restricted state as a delay until the start of the restricted state. to report the mileage of the The graceful mileage notified by the graceful warning section 12 when the straddled vehicle 1 transitions from the normal state to the first abnormal state is 300 miles.

In Specific Example 3, the timing to start the restricted state is set based on the travel distance after the transition to the first abnormal state and the driving state of the power source 2 . The control device 3 starts the restricted state when the mileage after transitioning to the first abnormal state is 500 miles or less and when the power source 2 is started. The control device 3 cannot clearly specify in advance the traveling distance from the transition to the first abnormal state to the start of the restricted state. Therefore, the control device 3 causes the grace period notification unit 12 to notify the grace period that is the same as or shorter than the actual grace period. After the traveled distance reaches 300 miles after transitioning to the first abnormal state, the grace period notification unit 12 notifies that the grace period is zero. FIG. 4 shows an example in which the restricted state is started while the grace period notified by the grace notice notification unit 12 continues to be zero. For example, controller 3 may initiate the restricted state at the start of a driving cycle prior to a driving cycle in which the vehicle may travel 500 miles after transitioning to the first abnormal state. Further, for example, the control device 3 may initiate the restricted state at the start of a driving cycle in which there is a possibility that the traveled distance after transitioning to the first abnormal state will reach 500 miles. Further, for example, the control device 3 may start the restricted state when the power source 2 is first started after the traveled distance reaches 300 miles after transitioning to the first abnormal state.

It should be noted that, as a modification of Specific Example 3, the restricted state may be started not only when the power source 2 is started, but also when the vehicle speed is equal to or lower than a predetermined speed. For example, in addition to starting the power source 2, the restricted state may also be initiated when the vehicle speed is zero. As another modification of Example 3, the restricted state may be initiated when the vehicle speed is equal to or lower than a predetermined vehicle speed regardless of whether or not the power source 2 is started. For example, the restricted state may be initiated when the vehicle speed is zero, whether or not the power source 2 is started.

As a modification of Specific Example 3, the timing at which the restricted state starts is set based on the travel time after transition to the first abnormal state instead of the travel distance after transition to the first abnormal state. may In this case, the delay notified by the delay notification unit 12 is the running time.

As a modification of Specific Example 3, the graceful mileage notified by the graceful warning unit 12 when the straddled vehicle 1 transitions from the normal state to the first abnormal state may be 500 miles. According to this modified example, the grace period notified by the grace period notification unit 12 at a certain time may be longer than the actual grace period. Therefore, in this modified example, the control device 3 may cause the grace period notification unit 12 to notify that the grace period is zero immediately before the restricted state is started. For example, the grace period notification unit 12 notifies that the grace period is zero during the period from the stoppage of the power source 2 that terminates the driving cycle immediately before the start of the restricted state to the power off of the straddled vehicle 1. may Instead of the period or in addition to the period, the grace period notification unit 12 determines that there is a grace period during the period from when the power of the straddled vehicle 1 immediately before starting the restricted state to when the power source 2 is started. You may notify that it is zero.

FIG. 5 shows specific examples 4 and 5 of the first embodiment. Specific example 4 is also a specific example of the third embodiment.
In specific example 4, when the abnormality notification unit 11 is notifying the first abnormal state, the delay notification unit 12 sets the delay from now until the start of the limit mode as a delay until the start of the limit state. to report the mileage of the The graceful running distance to the limit mode notified by the graceful warning section 12 when the straddled vehicle 1 transitions from the normal state to the first abnormal state is 500 miles. In Specific Example 4, the timing to start the restriction mode is set based only on the distance traveled after the transition to the first abnormal state. The limit mode is started when the traveled distance reaches 500 miles after transitioning to the first abnormal state. The restricted state is started when the vehicle speed satisfies a predetermined condition during execution of the restricted mode. The predetermined condition may be, for example, that the vehicle speed is higher than a predetermined threshold. FIG. 5 shows an example of when a restricted state is initiated after a restricted mode has been initiated.

As a modification of the specific example 4, the timing at which the limit mode is started is based on the travel time after the transition to the first abnormal state instead of the travel distance after the transition to the first abnormal state. may be set. In this case, the delay to the limit mode notified by the delay notification unit 12 is the running time.

Specific example 5 is also a specific example of the second embodiment. In specific example 5, when the abnormality notification unit 11 is notifying the first abnormal state, the delay notification unit 12 sets the delay from now until the start of the restricted state as a delay until the start of the restricted state. to report the mileage of the The graceful mileage notified by the graceful warning section 12 when the straddled vehicle 1 transitions from the normal state to the first abnormal state is 500 miles. In Specific Example 5, the timing to start the restricted state is set based on the traveled distance after the transition to the first abnormal state and the vehicle speed. The point in time when the traveled distance reaches 500 miles after the transition to the first abnormal state is defined as the first point in time. When the vehicle speed at the first point in time satisfies a predetermined condition, the restricted state is started from the first point in time. If the vehicle speed at the first point in time does not meet the predetermined condition, the restricted state is not initiated until after the first point in time the vehicle speed meets the predetermined condition. The predetermined condition may be, for example, that the vehicle speed is higher than a predetermined threshold. The control device 3 cannot clearly specify in advance the traveling distance from the transition to the first abnormal state to the start of the restricted state. Therefore, the control device 3 causes the grace period notification unit 12 to notify the grace period that is the same as or shorter than the actual grace period. After the traveled distance reaches 300 miles after transitioning to the first abnormal state, the grace period notification unit 12 notifies that the grace period is zero. FIG. 5 shows an example in which the restricted state is started while the grace period notified by the grace notice notification unit 12 continues to be zero.

As a modification of Example 5, the timing at which the restricted state is started is based on the travel time after transition to the first abnormal state instead of the travel distance after transition to the first abnormal state. may be set. In this case, the delay notified by the delay notification unit 12 is the running time.

FIG. 6 shows a specific example 6 of the first embodiment. Specific example 6 is also a specific example of the fourth embodiment. Example 6 is similar to Example 2. In specific example 6, when the abnormality notification unit 11 is notifying the first abnormal state, the delay notification unit 12 sets the delay from now until the start of the restricted state as a delay until the start of the restricted state. The number of times the power source 2 has been started, the traveled distance and the traveled time are reported. When the straddled vehicle 1 transitions from the normal state to the first abnormal state, the number of starts as a grace period notified by the grace notice section 12 is 10 times. The graceful mileage notified by the graceful warning section 12 when the straddled vehicle 1 transitions from the normal state to the first abnormal state is 500 miles. The running time as a grace period notified by the grace notice section 12 when the straddled vehicle 1 transitions from the normal state to the first abnormal state is 10 hours.

In Specific Example 6, the timing at which the restricted state starts is set based on the number of times the power source 2 has been started, the traveled distance, and the traveled time since the transition to the first abnormal state. In the limited state, any one of the number of times the power source 2 is started, the travel distance, or the travel time after the transition to the first abnormal state is the first, and the time from the transition to the first abnormal state to the start of the limited state is determined. Triggered when the grace value is reached. FIG. 6 shows the running time first among the number of times the power source 2 is started, the running distance, and the running time after the transition to the first abnormal state, and the time from the transition to the first abnormal state to the start of the restricted state. Here is an example when the grace value of is reached.

In specific example 6, the control device 3 determines the type and number of delays notified by the delay notification unit 12 according to the number of times the power source 2 is started from the transition to the first abnormal state to the present, the travel distance, and the travel time. to change. The control device 3 reduces the number of grace periods to be notified as the elapsed time after the transition to the first abnormal state increases. When the elapsed time after the transition to the first abnormal state becomes longer, the control device 3 causes the grace period notification unit 12 to notify the grace period which is estimated to be the shortest among the three grace periods. As a modification of the specific example 6, the control device 3 does not need to change the number of delays notified by the delay notification unit 12 .

As a modification of Example 6, the timing at which the restricted state is started is set based on the number of times the power source 2 has been started since the transition to the first abnormal state and the travel distance, and is not based on the travel time. may be set. In this case, the delay notified by the delay notification unit 12 is the number of times the power source 2 has been started and the traveled distance. As another modification of Example 6, the timing at which the restricted state is started is set based on the number of times the power source 2 is started and the running time after transition to the first abnormal state, and is not based on the running distance. may be set. In this case, the delay notified by the delay notification unit 12 is the number of times the power source 2 is started and the running time. As another modification of Specific Example 6, the timing at which the restricted state starts is set based on the travel distance and travel time after transition to the first abnormal state, and is not based on the number of times the power source 2 is started. may be set. In this case, the delay notified by the delay notification unit 12 is the running distance and the running time.

FIG. 7 shows a specific example 7 of the first embodiment. Specific example 7 is also a specific example of the second embodiment. Example 7 is similar to Example 3. In specific example 7, when the abnormality notification unit 11 is notifying the first abnormal state, the delay notification unit 12 sets the delay from now until the start of the restricted state as a delay until the start of the restricted state. The number of times the power source 2 has been started, the traveled distance and the traveled time are reported. When the straddled vehicle 1 transitions from the normal state to the first abnormal state, the number of starts as a grace period notified by the grace notice section 12 is 10 times. The graceful mileage notified by the graceful warning section 12 when the straddled vehicle 1 transitions from the normal state to the first abnormal state is 300 miles. The running time as a grace period notified by the grace notice section 12 when the straddled vehicle 1 transitions from the normal state to the first abnormal state is 6 hours.

In Specific Example 7, the timing at which the restricted state is started is set based on the number of times the power source 2 is started, the traveled distance and the traveled time after the transition to the first abnormal state, and the driving state of the power source 2. be. The control device 3 determines that the number of times the power source 2 has been started since the transition to the first abnormal state is 10 times or less, the travel distance since the transition to the first abnormal state is 500 miles or less, and the The limited state is started when the running time after the transition to the 1 abnormal state is 10 hours or less and when the power source 2 is started.

Power after transition to the first abnormal state when the mileage after transition to the first abnormal state is shorter than 500 miles and the driving time after transition to the first abnormal state is shorter than 10 hours If the number of starts of source 2 reaches 10, the limit condition is initiated at the tenth start. That is, the limited state is started when the delay in the number of starts notified by the delay notification unit 12 changes from a value greater than zero to zero.

The transition to the first abnormal state occurs when the number of times the power source 2 has been started since the transition to the first abnormal state is less than 10 and the running time since the transition to the first abnormal state is shorter than 10 hours. The mileage can reach 500 miles. In this case, it is not possible to specify in advance the mileage at the start of the power source 2 before the mileage reaches 500 miles. In addition, when the number of times the power source 2 is started after transitioning to the first abnormal state is less than 10 and the traveled distance after transitioning to the first abnormal state is shorter than 500 miles, the first abnormal state is entered. The running time after the transition may reach 10 hours. In this case, it is not possible to specify in advance the running time at the start of the power source 2 before the running time reaches 10 hours. Therefore, the control device 3 causes the delay notification unit 12 to notify the delay that is equal to or shorter than the actual delay as the delay in travel time and the delay in travel distance. After the traveled distance reaches 300 miles after the transition to the first abnormal state, the delay notification unit 12 notifies that the traveled distance is zero. After the travel time reaches 6 hours after the transition to the first abnormal state, the grace notice notification unit 12 notifies that the travel time grace is zero. FIG. 7 shows an example in which the restricted state is started while the running time grace period notified by the grace notice section 12 continues to be zero.

In specific example 7, the control device 3 determines the type and number of delays notified by the delay notification unit 12 according to the number of times the power source 2 is started from the transition to the first abnormal state to the present, the travel distance, and the travel time. to change. The control device 3 reduces the number of grace periods to be notified as the elapsed time after the transition to the first abnormal state increases. When the elapsed time after the transition to the first abnormal state becomes longer, the control device 3 causes the grace period notification unit 12 to notify the grace period which is estimated to be the shortest among the three grace periods. As a modification of the seventh specific example, the control device 3 does not need to change the number of grace periods notified by the grace period notification unit 12 .

As a modification of Example 7, the timing at which the restricted state is started is set based on the number of times the power source 2 has been started since the transition to the first abnormal state and the travel distance, and is not based on the travel time. may be set. In this case, the delay notified by the delay notification unit 12 is the number of times the power source 2 has been started and the traveled distance. As another modification of Example 7, the timing at which the restricted state is started is set based on the number of times the power source 2 is started and the running time after transition to the first abnormal state, and is not based on the running distance. may be set. In this case, the delay notified by the delay notification unit 12 is the number of times the power source 2 is started and the running time. As another modification of Example 7, the timing at which the restricted state is started is set based on the traveled distance and traveled time after transition to the first abnormal state, and is not based on the number of times the power source 2 is started. may be set. In this case, the delay notified by the delay notification unit 12 is the running distance and the running time.

As a modification of Specific Example 7, the restricted state may be started not only when the power source 2 is started, but also when the vehicle speed is equal to or lower than a predetermined speed. For example, in addition to starting the power source 2, the restricted state may also be initiated when the vehicle speed is zero. As another modification of Example 7, the restricted state may be initiated when the vehicle speed is equal to or lower than a predetermined vehicle speed regardless of whether or not the power source 2 is started. For example, the restricted state may be initiated when the vehicle speed is zero, whether or not the power source 2 is started. In these two modifications, when the traveled distance after the transition to the first abnormal state is shorter than 500 miles and the traveled time after the transition to the first abnormal state is shorter than 10 hours, the first abnormal state , the number of times the power source 2 is started may reach 10 times. In this case, it is not possible to specify in advance the number of starts when the vehicle speed is equal to or lower than a predetermined speed before the number of starts reaches ten. Therefore, the control device 3 may cause the delay notification section 12 to notify the delay that is the same as or shorter than the actual delay as the delay in the number of times of starting. In other words, the number of times the straddled vehicle 1 has been started as a grace period notified by the grace notice section 12 when the straddled vehicle 1 transitions from the normal state to the first abnormal state may be less than 10 times.

As a modification of Specific Example 7, the travel distance and travel time as grace periods notified by the grace notice notification unit 12 when the straddled vehicle 1 transitions from the normal state to the first abnormal state may be 500 miles and 10 hours. . According to this modified example, the grace period notified by the grace period notification unit 12 at a certain time may be longer than the actual grace period. Therefore, in this modified example, the control device 3 may cause the grace period notification unit 12 to notify that the grace period is zero immediately before the restricted state is started. For example, the grace period notification unit 12 notifies that the grace period is zero during the period from the stoppage of the power source 2 that terminates the driving cycle immediately before the start of the restricted state to the power off of the straddled vehicle 1. may Instead of the period or in addition to the period, the grace period notification unit 12 determines that there is a grace period during the period from when the power of the straddled vehicle 1 immediately before starting the restricted state to when the power source 2 is started. You may notify that it is zero.

FIG. 8 shows specific examples 8 and 9 of the first embodiment. Specific example 8 is also a specific example of the third embodiment. Example 8 is similar to Example 4. In specific example 8, when the abnormality notification unit 11 is notifying the first abnormal state, the delay notification unit 12 sets the delay from now until the start of the limit mode as a delay until the start of the limit state. The number of times the power source 2 has been started, the traveled distance and the traveled time are reported. When the straddled vehicle 1 transitions from the normal state to the first abnormal state, the number of starts as a delay to the limit mode notified by the delay notification section 12 is 10 times. The travel distance to the limit mode notified by the delay warning unit 12 when the straddled vehicle 1 transitions from the normal state to the first abnormal state is 500 miles. The running time as a grace period to the limit mode notified by the grace notice section 12 when the straddled vehicle 1 transitions from the normal state to the first abnormal state is 10 hours.

In Specific Example 8, the timing to start the limit mode is set based on the number of times the power source 2 has been started, the travel distance, and the travel time after the transition to the first abnormal state. In the limit mode, any one of the number of times the power source 2 is started after transition to the first abnormal state, the travel distance, or the travel time is the first, and the time from the transition to the first abnormal state to the start of the limit mode is determined. Triggered when the grace value is reached. FIG. 8 shows the running time first among the number of times the power source 2 is started, the running distance and the running time after the transition to the first abnormal state, and the time from the transition to the first abnormal state to the start of the limit mode. Here is an example when the grace value of is reached. The restricted state is started when the vehicle speed satisfies a predetermined condition during execution of the restricted mode. The predetermined condition may be, for example, that the vehicle speed is higher than a predetermined threshold. FIG. 8 shows an example where the restricted state is initiated after the restricted mode has been initiated.

In specific example 8, the control device 3 determines the type and number of delays until the limit mode notified by the delay notification unit 12, the number of starts of the power source 2 from the transition to the first abnormal state to the present, the travel distance, and the number of delays. Change according to running time. The control device 3 reduces the number of delays before the limit mode notified as the elapsed time after the transition to the first abnormal state increases. When the elapsed time after the transition to the first abnormal state becomes longer, the control device 3 causes the grace period notification unit 12 to notify the grace period which is estimated to be the shortest among the three grace periods. As a modification of the eighth example, the control device 3 does not need to change the number of delays until the limit mode notified by the delay notification unit 12 .

In Concrete Example 8, once the restricted state is started, it continues until the straddled vehicle 1 recovers from the first abnormal state to the normal state regardless of the vehicle speed. As a modification of Example 8, the restricted state may be set only when the vehicle speed satisfies a predetermined condition. That is, when the vehicle speed no longer satisfies a predetermined condition after the restricted state is started, the restricted state may be canceled even if the straddled vehicle 1 has not recovered from the first abnormal state to the normal state. After that, the limited state is resumed when the vehicle speed satisfies a predetermined condition.

As a modification of Example 8, the timing at which the limit mode is started is set based on the number of times the power source 2 has been started since the transition to the first abnormal state and the travel distance, and is not based on the travel time. may be set. In this case, the delay to the limit mode notified by the delay notification unit 12 is the number of times the power source 2 is started and the traveled distance. As another modification of Example 8, the timing at which the limit mode is started is set based on the number of times the power source 2 has been started and the running time after transition to the first abnormal state, and is not based on the running distance. may be set. In this case, the delay to the limit mode notified by the delay notification unit 12 is the number of times the power source 2 is started and the running time. As another modification of Example 8, the timing at which the limit mode is started is set based on the travel distance and travel time after the transition to the first abnormal state, and is not based on the number of times the power source 2 is started. may be set. In this case, the delay to the limit mode notified by the delay notification unit 12 is the running distance and the running time.

Specific example 9 is also a specific example of the second embodiment. Example 9 is similar to Example 5. In specific example 9, when the abnormality notification unit 11 is notifying the first abnormal state, the delay notification unit 12 sets the delay from now until the start of the restricted state as a delay until the start of the restricted state. The number of times the power source 2 has been started, the traveled distance and the traveled time are reported. When the straddled vehicle 1 transitions from the normal state to the first abnormal state, the number of starts as a grace period notified by the grace notice section 12 is 10 times. The graceful mileage notified by the graceful warning section 12 when the straddled vehicle 1 transitions from the normal state to the first abnormal state is 500 miles. The running time as a grace period notified by the grace notice section 12 when the straddled vehicle 1 transitions from the normal state to the first abnormal state is 10 hours.

In Specific Example 9, the timing for starting the restricted state is set based on the number of times the power source 2 has been started since the transition to the first abnormal state, the travel distance and travel time, and the vehicle speed. Any one of the number of times the power source 2 has been started after transitioning to the first abnormal state, the traveling distance, or the traveling time is the value of the grace period from the transition to the first abnormal state to the start of the restricted state. The time point reached is the second time point. If the vehicle speed at the second time satisfies a predetermined condition, the restricted state is started from the second time. If the vehicle speed at the second point in time does not satisfy the predetermined condition, the restricted state is not initiated until the vehicle speed satisfies the predetermined condition after the second point in time. The predetermined condition may be, for example, that the vehicle speed is higher than a predetermined threshold. The control device 3 cannot clearly specify in advance the number of times the power source 2 is started, the travel distance, and the travel time from the transition to the first abnormal state to the start of the restricted state. Therefore, the control device 3 causes the grace period notification unit 12 to notify the grace period that is the same as or shorter than the actual grace period. After the second point in time, the grace period notification unit 12 notifies that the grace period is zero. FIG. 9 shows an example in which the restricted state is started while the running time grace period notified by the grace notice section 12 continues to be zero.

In specific example 9, the control device 3 determines the type and number of delays notified by the delay notification unit 12 according to the number of times the power source 2 has been started from the transition to the first abnormal state to the present, the travel distance, and the travel time. to change. The control device 3 reduces the number of grace periods to be notified as the elapsed time after the transition to the first abnormal state increases. When the elapsed time after the transition to the first abnormal state becomes longer, the control device 3 causes the grace period notification unit 12 to notify the grace period which is estimated to be the shortest among the three grace periods. As a modification of the ninth specific example, the control device 3 does not need to change the number of grace periods notified by the grace period notification unit 12 .

In Concrete Example 9, once the restricted state is started, it continues until the straddled vehicle 1 recovers from the first abnormal state to the normal state regardless of the vehicle speed. As a modification of the ninth example, the restricted state may be set only when the vehicle speed satisfies a predetermined condition. That is, when the vehicle speed no longer satisfies a predetermined condition after the restricted state is started, the restricted state may be canceled even if the straddled vehicle 1 has not recovered from the first abnormal state to the normal state. After that, the limited state is resumed when the vehicle speed satisfies a predetermined condition.

As a modification of Example 9, the timing at which the restricted state is started is set based on the number of times the power source 2 has been started since the transition to the first abnormal state and the traveled distance, and is not based on the traveled time. may be set. In this case, the delay notified by the delay notification unit 12 is the number of times the power source 2 has been started and the traveled distance. As another modification of Example 9, the timing at which the restricted state is started is set based on the number of times the power source 2 has been started and the running time after transition to the first abnormal state, and is not based on the running distance. may be set. In this case, the delay notified by the delay notification unit 12 is the number of times the power source 2 is started and the running time. As another modification of Specific Example 9, the timing at which the restricted state is started is set based on the traveled distance and traveled time after the transition to the first abnormal state, and is not based on the number of times the power source 2 is started. may be set. In this case, the delay notified by the delay notification unit 12 is the running distance and the running time.

It should be noted that the numerical values of the number of times the power source 2 is started, the traveling distance, and the traveling time described in the explanations of specific examples 1 to 9 of the first embodiment are examples, and are not limited to these numerical values. Moreover, Specific Examples 1 to 9 and modifications thereof may be combined as appropriate.
