Abstract

DC60 (10/09/55) The tool kit is designed to determine whether the engine can be driven depending on the motorcycle's surrounding environment without providing a mechanism focused on determining the battery level. ECU 60 includes: Switch detector 603, which detects the main switch 66 changing from off to on; Drive controller 601, which drives the engine drive components when switch detector 603 detects that main switch 66 has changed from off to on; Start detector 604, which detects engine start 44; Voltage detector 602, which senses the voltage at battery 64 after the engine drive components start to be driven and before start detector 604 detects engine start 44; Warning controller 605, which provides warning light 62 with warning instructions if the voltage value sensed by the voltage detector 602 is not greater than the first threshold. The tool kit is designed to determine whether the engine can be driven depending on the surrounding environment. The surrounding environment of the motorcycle, without any mechanisms designed to determine the battery level, includes the following ECU 60: Switch detector 603, which detects the master switch 66 changing from off to on; Motion controller 601, which powers the engine drive parts when it detects switch 603 detecting that master switch 66 has changed from off to on; Starter detector 604, which detects engine start-up 44; Voltage detector 602, which senses the voltage at battery 64 after the engine drive parts are powered on and before the starter detector 604 detects engine start-up 44; and Warning controller 605, which provides a warning light 62 with a warning instruction if the voltage value sensed by the voltage detector 602 is not greater than the first threshold.
