  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the present embodiment, a case where the present invention is applied to a scooter type motorcycle 1 will be described as an example. In the following description, the up and down, left and right, and front and rear directions indicate directions viewed from the driver who rides the motorcycle 1.

  First, the overall configuration of the motorcycle 1 will be described with reference to FIGS. 1 and 2. Here, FIG. 1 is a side view showing the motorcycle 1, and FIG. 2 is a perspective view showing a front portion of the motorcycle 1 from the rear.

  The motorcycle 1 is provided with a vehicle body frame that constitutes a framework of the vehicle body. The vehicle body frame is entirely covered by a vehicle body cover 2. A front fork 3 is supported at the front end portion of the vehicle body frame, a front wheel 4 is pivotally supported at the lower end of the front fork 3, and a front fender 5 is provided so as to cover the front wheel 4. A pair of left and right handlebars 6 and 7 for steering the front wheel 4 are provided at the upper end of the front fork 3, and rearview mirrors 8 and 9 are provided above the handlebars 6 and 7, respectively.

  Handle grips 10 and 11 are respectively attached to the end portions of the left and right handle bars 6 and 7, and brake bars 12 and 13 are disposed in front of the handle grips 10 and 11, respectively. Further, switch units 14 and 15 are mounted at positions adjacent to the handle grips 10 and 11, respectively.

  A rear end of the swing arm 16 is supported at the rear of the vehicle body frame, a rear wheel 17 as a drive wheel is pivotally supported on the swing arm 16, and a rear fender 18 is provided so as to cover the rear wheel 17. A driver seat 19 is provided above the rear part of the vehicle body frame.

  FIG. 3 is an enlarged perspective view of the right handle portion of FIG. 2, and a plurality of switch groups are arranged in the switch unit 15 at positions that are visible from the driver side who rides on the motorcycle 1. In addition, since the well-known technique is employ | adopted regarding the left switch unit 14, detailed description is abbreviate | omitted.

  The switch unit 15 will be described in detail. An engine stop switch (kill switch) 20 is disposed near the upper surface of the switch unit 15, and a hazard switch 21 that can swing in the vehicle width direction near the center of the rear surface of the switch unit 15. Is arranged. Further, the switch unit 15 is provided with a starter switch 22 in the vicinity of the lower part of the hazard switch 21, and this starter switch 22 also functions as a mode switching switch for switching the traveling mode of the motorcycle 1. It is configured. The traveling mode includes an idle stop permission mode that permits the idle stop control and an idle stop non-permission mode that does not permit the idle stop control.

  FIG. 4 is a block diagram showing the configuration of the control device 30 of the motorcycle 1. In FIG. 4, the solid line shows the power supply circuit, and the broken line shows the signal flow. The control device 30 includes a controller 31 that is supplied with power by a battery 32. The controller 31 also functions as an engine start request determination unit. Various signals are input to the controller 31 from a group of switches such as a brake switch 34 and a starter switch 22, and a group of sensors such as a vehicle speed sensor 24, a crank rotation sensor 25, a water temperature sensor 26, and a throttle position sensor 27. Based on this, the starter motor relay 28, the fuel injection / ignition component 29, and the like are controlled.

  Next, the operation of the control device 30 of the motorcycle 1 according to the embodiment of the present invention will be described with reference to FIGS. 4, 5, and 6. 5 is a flowchart showing a main processing flow of the control device 30 of the motorcycle 1, and FIG. 6 is a flowchart showing an engine start request determination processing flow of the control device 30 of the motorcycle 1.

  As shown in FIG. 5, first, the controller 31 determines whether or not the starter switch 22 is turned on (see S10). As a result, if the controller 31 determines that the starter switch 22 has been turned on, the controller 31 proceeds to S20 of the next step, and if not, repeats the process of S10 of the above step.

  In S20 of the next step, the controller 31 executes an engine start request determination process.

  As shown in FIG. 6, in this engine start request determination process, first, the controller 31 determines whether or not the brake levers 12 and 13 have been operated (see S21). As a result, when the controller 31 determines that the brake levers 12 and 13 are operated and the brake switch 34 is in the ON state, whether or not the engine is stopped by a signal output from the crank rotation sensor 25 is further determined. Is determined (see S22), and if it is determined that the engine is stopped, it is determined that there is a request to start the engine (see S23).

  On the other hand, if the controller 31 determines in step S21 that the brake switch 34 is not on, or if it is determined in step S22 that the engine is not stopped, the controller 31 determines that there is no engine start request. (Refer to S24).

  When it is determined that there is an engine start request in the engine start request processing, the controller 31 outputs an ON signal to the starter motor relay 28 and supplies power to the starter motor 33 as shown in FIG. The starter motor 33 is driven (see S40 in FIG. 5).

  On the other hand, when it is determined in the engine start request process that there is no engine start request, the controller 31 outputs an off signal to the starter motor relay 28 to cut off the power to the starter motor 33, as shown in FIG. As a result, the controller 31 causes the starter switch 22 to function as a mode switch, and executes a traveling mode switching operation between the idle stop permission mode and the idle stop permission mode (see S50).

  If the detection values of the vehicle speed sensor 24, the crank rotation sensor 25, the water temperature sensor 26, etc. satisfy predetermined conditions when the mode is switched to the idle stop permission mode, the controller 31 automatically stops the engine while After the stop, the engine is automatically started by detecting the throttle opening by the throttle position sensor 27.

  When the starter switch 22 functions as a mode switch, it is preferable that the travel mode switching operation is executed only when the starter switch 22 is pressed for a few seconds. Thereby, it can prevent more reliably that driving | running | working mode switching operation | movement is performed contrary to a driver | operator's intention.

  As described above, according to the embodiment of the present invention, since the starter switch 22 can be used in common as a mode changeover switch, the switch units 14 and 15 are not increased in size, and the driver can easily and reliably perform the operation. Each switch can be operated and the operability can be improved.

  In addition, since the number of switches can be reduced and the switch unit is simplified, it is possible to prevent an erroneous operation by the driver and to reduce costs.

  In the above-described embodiment, the idle stop permission mode and the idle stop non-permission mode are described as examples of the travel mode. However, the present invention is not limited to this type of travel mode. For example, the combustion mode The present invention is also applicable to other travel modes such as switching between the automatic transmission mode and the manual transmission mode.

  In the above description of the embodiment, the case where the present invention is applied to the scooter type motorcycle 1 has been described. However, this is merely an example, and the present invention is also applied to other types of small vehicles. It goes without saying that it is possible.
