  • the power supply control ECU 101 may switch the power supply state of the straddle-type vehicle 10 from a power-on state in which the ignition power supply and the accessory power supply are on to an accessory-on state in which only the accessory power supply is on. Further, for example, the power supply control ECU 101 may switch the power supply state of the straddle-type vehicle 10 from a power-on state in which the ignition power supply and the accessory power supply are on to a power-off state in which both of them are off.

FIG. 8 is a variation of the flowchart of FIG. 5, and shows processing when the idle stop ECU 102 restarts the engine 40 that has been automatically stopped based on a predetermined condition. More specifically, in the flowchart of FIG. 8, the conditions for restarting the engine 40 are changed when the notification of S303 of FIG. 6 is performed and when not. This flowchart is periodically executed, for example, when the engine 40 is automatically stopped based on the flowchart of FIG.

  • S503 to S505 are processes when the notification of S303 is not performed, and are the same processes as S202 to S204. Further, S506 is the same processing as S205. Therefore, description of each step is omitted.

  • S507 and S508 are processes when the notification of S303 is performed.
  • S507 if the gear position of the manual transmission 42 is neutral, the idle stop ECU 102 proceeds to S506 to restart the engine 40. If the gear position is 1st, the idle stop ECU 102 proceeds to S508. As a result, for example, when the rider switches the gear position of the manual transmission 42 from in gear (1st gear) to neutral, the engine 40 is restarted.
