JP5720383B2 - Idling stop control device for motorcycle and motorcycle having the same - Google Patents

Description

  The present invention relates to an idling stop control device for a motorcycle and a motorcycle including the same, and more particularly to an apparatus that effectively uses an idling stop function in a motorcycle.

  It is known that various vehicles that run by driving an engine (internal combustion engine) have an idling stop function that stops the engine operation at a predetermined timing when the running is stopped from the viewpoint of achieving energy saving and reducing environmental pollution. (Note that the idling stop may be simply referred to as an idle stop). In particular, the idling stop function is rapidly spreading in four-wheeled vehicles. In the idling stop function, control is performed to temporarily stop the engine when the stop state is continued even after a predetermined time has elapsed since the stop of traveling.

  As this kind of idling stop function, especially in a four-wheeled vehicle, there is a so-called creep phenomenon that transmits a driving force for driving at an extremely low speed even when idling to the driving wheel. One of the idling stop conditions is that the brake pedal is being depressed. On the other hand, the engine stopped by the idling stop function is controlled to be restarted by determining that the operation of depressing the brake pedal is released as a request for resuming traveling.

  This type of idling stop function has also been adopted in motorcycles, and various devices have been made due to circumstances unique to the motorcycle (for example, Patent Document 1). However, since the motorcycle does not have the above-described creep phenomenon, the motorcycle does not travel during idling even if the brake is not operated on a flat ground. Therefore, the brake operation is not set as an idling stop execution condition. In addition, the engine stopped by the idling stop function performs control to restart the engine by determining that the throttle operation itself is a request for restarting traveling.

One or both of the brake operation members for the front brake and the rear brake for stopping and stopping the travel are set, and the idling stop request determination unit performs the specific operation of the brake operation member by the operation detection unit. When the detection information is detected, the idling stop request is determined.

  In a third aspect of the invention relating to an idling stop control device for a motorcycle that solves the above-described problem, in addition to the specific matter of the second aspect, the idling stop request determining unit is When the specific operation for shifting from the operation state of the brake operation member that releases the travel restriction of the motorcycle to the operation state of the brake operation member that restricts the travel of the motorcycle is detected from detection information of the operation detection unit The idling stop request is determined.

  According to a fourth aspect of the invention relating to an idling stop control device for a motorcycle that solves the above-mentioned problems, in addition to the specific matter of the second or third aspect, the idling stop request determination unit is configured to operate the brake operation for the front brake. When the specific operation of both the member and the brake operation member for the rear brake is simultaneously detected from the detection information of the operation detection unit, the idling stop request is determined.

  In a fifth aspect of the invention relating to an idling stop control device for a motorcycle that solves the above-mentioned problems, in addition to the specific matter of the second or third aspect, the idling stop request determination unit is configured to stop running of the motorcycle. In this state, the brake operation member for the rear brake continues the operation state for restricting the traveling of the motorcycle, while the brake operation member for the front brake cancels the travel restriction of the motorcycle. When the specific operation that shifts to the operation state to be restricted is detected from detection information of the operation detection unit, the idling stop request is determined.

  According to a sixth aspect of the invention relating to the idling stop control device for a motorcycle that solves the above-mentioned problems, in addition to the specific matter of the first aspect, the engine is used as the operation unit to be detected by the operation detection unit. A starter switch to be started by driving the motor is set, and after the engine is started, the operation of the starter switch is disconnected from the drive of the starter motor.

  A seventh aspect of the invention relating to an idling stop control device for a motorcycle that solves the above-described problems is the timing when the motorcycle stops traveling in addition to the specific matter of any one of the first to sixth aspects. A timer that counts the elapsed time from the time when the engine control unit counts the elapsed time that exceeds a preset time set in advance when the other idling stop conditions are met The idling stop is executed.

  A first aspect of the invention relating to a motorcycle that solves the above problems includes an engine that generates a driving force for traveling, the idling stop control device for any one of the motorcycles described above, and driving driving rotation of the engine. A continuously variable transmission that transmits to a drive shaft to which the wheels are connected, and both the brake operation member for the front brake and the brake operation member for the rear brake are arranged on the right and left of the handle. Is.

  As described above, according to the first aspect of the idling stop control device for a motorcycle according to the present invention, when other idling stop conditions are met when the specific operation is detected, the idling stop control is executed to execute the engine. When the travel request operation is detected during the idling stop period, the engine can be started and restarted to start traveling. Therefore, the rider who drives the motorcycle can perform a specific operation and can temporarily stop the engine in a situation where idling can be stopped without waiting until the set period elapses from the stop of traveling.

  According to the second aspect of the idling stop control device for a motorcycle according to the present invention, the operation of the brake operating member for the front brake or the rear brake can be set as a specific operation for performing the idling stop, The specific operation can be performed continuously after the operation of stopping from the running state. Therefore, the idling stop can be carried out smoothly without adding a special idling stop switch and without changing the operation target.

  According to the third aspect of the idling stop control device for a motorcycle according to the present invention, the operation of deliberately applying the brake from the state where the brake is not applied after the stop of traveling is performed, for example, to stop the operation from the traveling state. After stopping after restricting (driving restriction), the brake operation is once released and the brake operation is performed again, or the brake operation is performed after the vehicle stops running without using the brake because it is in a low speed state. Thus, idling stop can be implemented. Therefore, the brakes are specially applied to motorcycles that do not need to be braked when the vehicle is stopped because there is no so-called creep phenomenon, which is extremely low speed when idling, as in four-wheeled vehicles. It can be set as a specific operation to be operated, and the idling stop can be executed consciously.

  According to the fourth aspect of the idling stop control device for a motorcycle according to the present invention, the idling stop request can be made only after the same specific operation is performed on the front brake and the rear brake at the same time. In addition, it is possible to avoid inadvertently performing idling stop to stop the engine.

  According to the fifth aspect of the idling stop control device for a motorcycle according to the present invention, it is possible to make an idling stop request only when a specific operation of the front brake is performed while using the rear brake, and the vehicle is moved backward or forward on a slope. The idling stop can be performed while applying the brake so that the engine is not used, and it is possible to prevent the engine from being inadvertently stopped by inadvertently performing the idling stop although not desired.

  According to the sixth aspect of the idling stop control device for a motorcycle according to the present invention, the operation of the starter switch after the engine is started can be set as the specific operation for performing the idling stop. The starter motor is not unnecessarily driven after starting. Therefore, without adding a special idling stop switch, an operation that does not need to be performed after the start can be set as a specific operation for performing idling stop so as not to cause a malfunction.

  According to the seventh aspect of the idling stop control device for a motorcycle according to the present invention, not only when performing a specific operation, but also when other idling stop conditions are met when a predetermined time has elapsed since the traveling stop, The engine can be temporarily stopped by executing stop control. Therefore, idling stop can be performed without forcing a specific operation.

  According to the eighth and ninth aspects of the idling stop control apparatus for a motorcycle according to the present invention, the idling stop can be performed by cutting the fuel supply to the engine and its fuel ignition. Therefore, idling stop can be executed easily. At this time, it is preferable that the engine is temporarily stopped in a state where it can be started easily and quickly so that the engine can be restarted.

  According to the first aspect of the motorcycle of the present invention, not the so-called motorcycle that manually changes the gear ratio of the transmission, but a function of automatically shifting without permission, and the brake operation is performed on the left and right sides of the steering wheel. One aspect of the idling stop control device for a motorcycle according to the present invention can be mounted on the motorcycle, and the idling stop can be used comfortably.

  In FIG. 1, a motorcycle 10 includes a front seat 11 on which a rider (driver) sits, a rear seat 12 on which a second person sits when two people ride, a step 14 in which the rider and the second person step on, The steering wheel 15 is operated to run while holding both ends, the front wheel 16 disposed at the lower part on the handle 15 side, the rear wheel (not shown) disposed at the lower part on the rear seat 12 side, and the upper side of the front wheel 16 The two-lamp headlight 17 disposed on the rear wheel, a tail lamp (not shown) disposed on the upper side of the rear wheel, and a muffler 18 for exhausting combustion gas of the engine 41 described later. The front seat 11 and the rear seat 12 are integrally formed to open and close the storage space under the seat, and expose and cover a fuel filler port of a fuel tank (not shown). A sliding backrest 13 is disposed between the part seat 11 and the rear seat 12.

  Around the handle 15, various parts that are operated when traveling are arranged. A throttle grip 21 is arranged at the right hand side end of the handle 15, and a fixed grip 22 is arranged at the left hand side end thereof. Has been placed. A front brake lever 23 for braking the front wheel 16 is disposed at the right hand side end of the handle 15, and a rear brake lever 24 for operating the rear wheel brake is disposed at the left hand side end of the handle 15. Is arranged. Note that rear mirrors 25 and 26 are also disposed at both ends of the handle 15.

  As shown in the related block diagram of FIG. 2, the motorcycle 10 has an ignition key switch 31 disposed at the center on the upper side of the handle 15. A start button switch 32 for starting the engine 41 and a kill switch 33 for forcibly stopping driving of the engine 41 are arranged. Although not shown in the drawing, the left end of the handle 15 is not shown, but a horn button switch for outputting an alarm sound from the horn, a changeover switch for operating the high beam / low beam of the headlight 17, and blinking when turning right or left. A blinker changeover switch is also arranged. Further, an indicator 35 for displaying various information such as a traveling speed is disposed on the upper side near the center of the handle 15. Note that the buzzer 34 is set to output an alarm sound when an abnormality is detected, other than a manual horn.

  Under the seats 11 and 12, an engine (internal combustion engine) 41 that generates driving force for rotationally driving the rear wheels, and gasoline is injected into the combustion chamber of the engine 41 from the fuel tank by an injector. A fuel injection ignition device 42 that ignites by a plug, a transmission (continuously variable transmission) 43 that is interposed between a drive shaft and a rear wheel of the engine 41 and continuously transmits drive rotation, and a power supply to the electrical system of each part , A starter motor 45 that starts the engine 41 by rotating the crank of the engine 41 and driving the piston by supplying power from the battery 44, and various sensors disposed in each part described later And a controller 46 for receiving a detection signal such as the above and centrally controlling each part of the apparatus. Here, although not shown in the figure, the controller 46 uses the RAM as a work area while using various parameters in accordance with a control processing program stored in the ROM so as to be readable in advance. Is supposed to run.

  The motorcycle 10 adjusts the gasoline supply to the engine 41 by operating the throttle grip 21 at the right-hand side end of the handle 15 to increase / decrease the traveling speed, and brake levers 23 on both ends of the handle 15. , 24 is a so-called scooter type that operates by operating braking / stopping. In addition, when this traveling is stopped, the rider who sits on the front seat 11 sits and supports the rider, and does not fall by standing a center stand (not shown) or by pulling the side stand obliquely from the side. It is designed to maintain the state.

  At this time, the controller 46 detects that the ignition key switch 31 is turned on, the brake switch 57 is turned on and the brake operation is being performed, and the starter motor relay 54 is pressed when the start button switch 32 is pressed. Is turned on to supply power from the battery 44 to the starter motor 45 to start the engine 41. The engine 41 is started by detecting that the side stand switch 52 is ON and the side stand is stored, and that the kill switch 33 remains OFF and the start of the engine 41 is not prohibited. It is a condition.

  Thereafter, the controller 46 has a fuel injection ignition device 42 in the engine 41 in accordance with the twist amount (throttle opening) of the throttle grip 21 at the right hand side end of the handle 15 detected by the throttle position sensor (travel request detection unit) 55. The travel speed can be adjusted while adjusting the amount of gasoline that is injected and ignited, and the travel speed detected by the vehicle speed sensor 56 at that time is displayed by the indicator 35 at the upper center of the handle 15. ing. At this time, the rider operates the brake levers 23 and 24, which detect whether the brake switch 57 is ON / OFF, and adjusts the hydraulic pressure to apply the brake in accordance with the grip amount (stroke) to perform braking / stopping. At the same time, the controller 46 lights the tail lamp simultaneously with the detection of the operation of the brake levers 23 and 24 by the brake switch 57.

  In the motorcycle 10, a control processing program for performing idling stop for temporarily stopping the engine 41 in a state in which the engine 41 can be restarted immediately when predetermined conditions are met can be read and executed by the CPU in the ROM of the controller 46. Stored in advance. That is, the controller 46 constitutes an engine control unit.

  Specifically, the motorcycle 10 can select whether or not to use the idling stop function. The idling stop changeover switch 61 is provided at the right hand side end portion of the handle 15 with the throttle grip 21, the start button switch 32, and the kill switch 33. It is arranged with. Whether the controller 46 (CPU) satisfies the idling stop permission condition and execution condition described later based on the control processing program and various parameters in the ROM when the idling stop changeover switch 61 is selected to be ON. It is determined whether or not, and when both are satisfied, an idling stop control process is executed. The idling stop permission condition and execution condition include the water temperature detected by the coolant temperature sensor 62 installed in a radiator (not shown) that cools the engine 41 in the detection / detection information of the various switches and sensors described above. Further, the number of rotations of the crankshaft (the number of rotations of the engine 41) detected by the crank rotation sensor 63 installed in the engine 41, and the detection of the seating sensor 53 that detects that the rider is sitting on the front seat 11 It is determined whether the signal and the detection signal of the center stand switch 51 for detecting the state where the center stand is set up are satisfied.

The controller 46 checks the operating state of the motorcycle 10 as the idling stop permission condition, and when all of the following conditions (1) to (6) are satisfied, the idling stop is performed. Implementation of control processing is permitted.
(1) The idling stop changeover switch 61 is in the ON state, and the temporary stop of the engine 41 is selected by the rider.
(2) The crankshaft rotation speed detected by the crank rotation sensor 63 is equal to or higher than the idling rotation speed of the engine 41, and the engine 41 is in a driving state in which the idling stop can be used effectively.
(3) The water temperature detected by the water temperature sensor 62 is within a set range, for example, 60 ° C. to 110 ° C., and has been warmed up so that the engine 41 can be restarted smoothly.
(4) When the seating sensor 53 detects that the rider is sitting on the front seat 11 and the engine 41 is temporarily stopped before being noticed by the idling stop function, it is misunderstood. Being in a state that will not fit theft.
(5) There is a history of traveling at a set speed or higher, for example, 10 km / h or higher, and the vehicle is traveling, such as waiting for a signal to effectively use an idling stop.
(6) The center stand switch 51 is not in the ON state, for example, in a state where the idling stop is effectively used, not at the time of warming up the center stand with the engine 41 running. When the side stand switch 52 is in the OFF state (when it is detected that the side stand is out), the engine 41 is stopped by the drive prohibition control.

  Here, in the present embodiment, the idling stop permission condition is that all of the above conditions (1) to (6) are all met, but not all are essential, and at least the above conditions (1) to (6). You may make it a condition to satisfy (3).

Further, the controller 46 confirms what traveling operation state the motorcycle 10 is in as an idling stop execution condition, and satisfies all the following conditions (A) to (C): Carry out idling stop control processing. After that, the controller 46 temporarily stops the engine 41 in a state where it can be quickly restarted when either one of the next timing conditions (D-1) or (D-2) is detected. It has become.
(A) The twist amount of the throttle grip 21 detected by the throttle position sensor 55 is zero, and the rider does not request travel (the throttle opening is fully closed).
(B) When the throttle is fully closed, the travel speed (vehicle speed) detected by the vehicle speed sensor 56 is 0 km / h, and the travel is stopped.
(C) When the throttle is fully closed, the rotation speed of the crankshaft detected by the crank rotation sensor 63 is the idling rotation speed, and the engine 41 is in a driving state waiting for a travel request.
(D-1) After the traveling speed (vehicle speed) detected by the vehicle speed sensor 56 becomes 0 km / h, the front brake lever 23 at the right-hand side end portion of the handle 15 is gripped to apply the front brake braking for the front wheels 16. And a specific operation is performed in which the detection signal of the brake switch 57 changes from OFF to ON.
(D-2) Even if the elapsed time after the travel speed (vehicle speed) detected by the vehicle speed sensor 56 reaches 0 km / h exceeds the set period T1, for example, exceeds 10 seconds, a travel request by the rider is issued. There must be no running stop.

  Specifically, as shown in the flowchart of FIG. 3, when the ignition key switch 31 is turned on, the controller 46 repeatedly executes the idling stop control process in parallel with other control processes. First, the idling stop permission conditions (1) to (6) are collected (step S11), whether or not all of them are satisfied (step S12), and an operating state that satisfies all of the idling stop permission conditions If it is confirmed that there is not, the process returns to step S11.

  In step S12, when the controller 46 confirms that it is in an operating state that satisfies all of the idling stop permission conditions, the idling stop execution conditions (A) to (C), (D-1), (D-2) is collected (step S13), and it is confirmed whether one of the conditions (D-1) or (D-2) is satisfied together with the conditions (A) to (C) (step S13). S14) When it is confirmed that there is no traveling operation state that satisfies one combination of the idling stop execution conditions, the process directly returns to step S11.

  As shown in the timing chart of FIG. 4, when the motorcycle 10 stops traveling at an intersection or the like from the traveling state, for example, the rider loosens the throttle grip 21 (FIG. 4 (a)). The rotational speed of the engine 41 detected by the rotation sensor 63 decreases (FIG. 4B). In parallel with this, when the rider grips the brake levers 23 and 24 and applies brake braking (FIG. 4C), the traveling speed (vehicle speed) detected by the vehicle speed sensor 56 is also reduced (FIG. 4D). )). Thereafter, the motorcycle 10 stops running while the crank rotation sensor 63 detects that the rotational speed of the engine 41 drops to the idling rotational speed and maintains the operating state (FIG. 4B). The vehicle speed sensor 56 detects zero travel speed (vehicle speed) (FIG. 4D).

  At this time, if it is confirmed in step S14 that the controller 46 is in an operating state satisfying all of the idling stop execution conditions (A) to (c), the controller 46 uses a count timer function (not shown) provided. The timer count-up for counting the elapsed time is started and continued (step S15), and it is confirmed whether or not the elapsed time (count) has passed 10 seconds (step S16).

  Next, at the beginning of the execution of the idling stop control process, the controller 46 confirms that 10 seconds have not elapsed in step S16. Therefore, the front brake lever 23 does not hold the engine stop control described later. Then, it is confirmed whether or not the front brake for the front wheel 16 is applied (step S17). In the case where the brake switch 57 is ON and the front brake is applied, and before confirming the front brake OFF flag “1” described later (step S18), the front brake ON flag is set to “1” (step S18). Step S19) Return to step S11.

  Even after returning to step S11, the controller 46 does not request the rider to start driving the throttle grip 21 to open the throttle, and the idling stop permission conditions (1) to (6) and the idling stop execution condition ( It is confirmed that the vehicle is in a travel stop state that satisfies all of A) to (C) (steps S11 to S13). After this confirmation, before the elapsed time in the travel stop state exceeds 10 seconds (steps S14 and S15), for example, since the motorcycle 10 has already stopped traveling, as shown at timing t1 in FIG. In some cases, the front brake lever 23 is released to intentionally release the front brake braking. In this case, the controller 46 confirms that the front brake lever 23 is released because the brake switch 57 is not ON (step S17), sets the front brake OFF flag to “1” (step S20), and returns to step S11. . At this time, the rear brake lever 24 may be gripped by the rider to apply the rear brake for the rear wheel so that the rear brake lever 24 does not move on a slope.

  In addition, after returning to step S11, before the elapsed time in the travel stop state satisfying all of the above conditions (1) to (6) and (A) to (C) exceeds 10 seconds (steps S11 to S16). For example, when the motorcycle 10 has already stopped running, but the rider consciously applies the front brake braking for the front wheels 16 by holding the front brake lever 23 as shown at timing t2 in FIG. There is. In this case, the controller 46 confirms the operation of the front brake lever 23 by turning on the brake switch 57 again (step S17), and confirms that the front brake OFF flag has already been set to “1” (step S17). Step S18) Since all of the idling stop execution conditions (A) to (C) and (D-1) are satisfied, the process proceeds to step S21, and the idling stop control process is performed as shown in FIG. 4 (e). The engine stop control at is performed. That is, the front brake lever 23 constitutes a brake operation member of the operation unit, the operation is set as a specific operation, the brake switch 57 constitutes an operation detection unit, and the controller 46 has an idling stop request determination unit and An engine control unit is configured. In the present embodiment, only the front brake lever 23 constitutes the brake member of the operation unit. However, the present invention is not limited to this, and only the rear brake lever 24 may be assigned, or may be assigned to both of them. However, considering the driving operation of the motorcycle 10, it is preferable that the rear brake is configured to be freely operable as in the present embodiment. In the present embodiment, although not particularly limited, it may be added to the idling stop execution condition that the rear brake braking by the rear brake lever 24 is maintained. Thus, it is possible to avoid idling stop and putting the engine in a stopped state.

  Further, at this time, it corresponds to pattern 1 in the list shown in FIG. 5, and the idling stop is executed 10 seconds before the motorcycle 10 stops traveling. Is stopped, the idling stop permission condition (2) and the idling stop execution condition (C) are not satisfied, and the controller 46 (CPU) is not confused.

  In this engine stop control, the controller 46 supplies gasoline from the fuel tank injected into the combustion chamber of the engine 41, for example, as shown in FIG. The engine is shut off (or ignition by a spark plug of gasoline injected into the combustion chamber of the engine 41 may be prohibited) (step S21). At this time, the controller 46 makes the rotation angle of the crankshaft detected by the crank rotation sensor 63 of the engine 41 that maintains the operating state at the idling rotation number detected by the crank rotation sensor 63 an angle that can be easily restarted. To stop. At the same time, the controller 46 stops and resets the timer count-up started in step S15 (step S22), and after clearing the previous brake ON / OFF flag set in steps S19 and S20 (step S23), step S11. Return to.

  After engine stop control processing is performed by the idling stop function after the motorcycle 10 has stopped running in this way, the front brake lever 23 is released as shown by the solid line in FIG. The brake switch 57 may be turned OFF again (after releasing the front brake braking), and as shown by a two-dot chain line in FIG. 4C, the front brake lever 23 is held as it is (the front brake braking is maintained). The brake switch 57 may be left on.

  By the way, the rider may stop traveling by causing the motorcycle 10 to stand at foot by coasting at low speed without depending on braking. Even in this case, the controller 46 confirms that 10 seconds have not elapsed after stopping the traveling in step S16, and the brake switch 57 is turned off without the front brake lever 23 being held (the front brake is released). (Step S17), the front brake OFF flag is set to “1” (step S20), and the process returns to step S11. After this, as in the pattern 1 of FIG. 5, when the front brake lever 23 is grasped (front brake braking) and the brake switch 57 is confirmed to be turned on (step S17), the front brake OFF flag is already set to “1”. (Step S18) and the idling stop execution conditions (A) to (C) and (D-1) are all satisfied, so the process proceeds to Step S21 and the engine is stopped in the idling stop control process. Implement control. In this case, it corresponds to pattern 2 in the list shown in FIG. 5, and as with pattern 1, idling stop can be executed 10 seconds before the motorcycle 10 stops traveling.

  Conversely, before confirming that 10 seconds have elapsed in step S16, the controller 46 maintains the brake switch 57ON while the front brake lever 23 is being held (continue brake braking) so as to proceed to steps S17 to S19⇒S11. Brake (if the pattern is 3 in the list shown in FIG. 5), or the brake is kept released from the state in which the front brake lever 23 is held (step B17 is continued to be released) so as to proceed to steps S17 to S20 → S11. When the switch 57OFF is maintained (pattern 4 in the list shown in FIG. 5), or the motorcycle 10 is stopped after inertial driving without using brake braking so as to proceed to steps S17, S20 → S11. The brake switch 57 is maintained OFF while the front brake lever 23 is released from the beginning when the vehicle is stopped (the front brake is released). If the (pattern 5 of table shown in FIG. 5) is not performing the engine stop control process proceeds to step S21.

  On the other hand, after returning to step S11 repeatedly, the idling stop permission conditions (1) to (6) and the idling stop execution conditions (A) to (C) are satisfied and the running stop state is similarly satisfied. May exceed 10 seconds (steps S11 to S16). In this case, the controller 46 satisfies the idling stop execution timing condition (D-2) as in the general idling stop control process (patterns 3 to 5 in the list shown in FIG. 5). Proceeding to step S21, the engine stop control in the idling stop control process is performed without forcing a special operation, as indicated by a chain line in FIG. 4 (e).

  Then, when the throttle position sensor 55 detects a travel request in which the throttle grip 21 at the right hand side end of the handle 15 is twisted, the controller 46 causes the fuel injection ignition device 42 to move inside the engine 41 according to the twist amount (throttle opening). The gasoline is injected and ignited to start running.

  As described above, in the present embodiment, the front brake lever is used when the rider determines that the engine 41 may be stopped immediately before 10 seconds have elapsed since the motorcycle 10 stopped traveling, or when the traffic situation may allow the engine 41 to stop immediately. The engine 41 can be temporarily stopped on condition that other idling stop permission / execution conditions are prepared by performing only the 23 specific operations, and the rider can arbitrarily set up without providing a special execution switch. The idling stop can be executed smoothly by operating. Therefore, the idling stop time can be extended and the energy saving effect can be expanded.

  As another aspect of the present embodiment, although not shown, an alarm sound is output from not only the brake switch 57 that detects the operation of the front brake lever 23 but also other existing switches such as the buzzer 34. Operations such as a horn button switch to be turned on, a changeover switch for operating the high beam / low beam of the headlight 17 and a blinker changeover switch that blinks when turning right or left may be set as the idling stop execution request. However, since it is necessary to execute the assigned operation itself, it is more preferable to set the idling stop execution request to press the start button switch 32 (specific operation) while the engine 41 is activated. is there. Also in this aspect, as in the above-described embodiment, the rider can be aware and stop idling at an arbitrary timing. However, in this case, it is preferable to separate the starter motor 45 so that the starter motor 45 is not driven even when the start button switch 32 is pressed while the engine 41 is running.

  The scope of the present invention is not limited to the illustrated and described exemplary embodiments, but includes all embodiments that provide the same effects as those intended by the present invention. Further, the scope of the invention is not limited to the combinations of features of the invention defined by the claims, but may be defined by any desired combination of particular features among all the disclosed features. .

  Although one embodiment of the present invention has been described so far, it is needless to say that the present invention is not limited to the above-described embodiment, and may be implemented in various forms within the scope of the technical idea.
