INTERNAL COMBUSTION ENGINE STARTING DEVICE

摘要

An internal combustion engine starting device includes: a starting requirement determination device that determines whether an internal combustion engine is required to be started when the engine stops combustion by stopping fuel supply to the engine, and the vehicle is in a freewheel running; and a driving control device that drives and rotates a motor in a starter by increasing a driving voltage to the motor from a voltage changing device for changing the driving voltage supplied to the starter in a case where a travelling speed is high to be higher than in a case where the traveling speed is low, when the internal combustion engine is required to be started.

1. An internal combustion engine starting device for a vehicle that includes: an internal combustion engine as a traveling power source; a clutch device arranged on a power transmission path for linking an output shaft of the internal combustion engine and a driving wheel; a starter having a motor for applying an initial rotation to a ring gear linked to the output shaft; and a voltage changing device for changing a driving voltage supplied to the starter, the internal combustion engine starting device comprising:
a starting requirement determination device that determines whether the internal combustion engine is required to be started in a state where the internal combustion engine stops combustion by stopping fuel supply to the internal combustion engine, and the vehicle is in a freewheel running with setting a clutch device to be in a power blocking state; and a driving control device that drives and rotates the motor by increasing a driving voltage supplied to the motor from the voltage changing device in a case where a travelling speed is high to be higher than in a case where the traveling speed is low, when the starting requirement determination device that determines that the internal combustion engine is required to be started.
