Title:
INTERNAL COMBUSTION ENGINE STARTING CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2014139427
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an internal combustion engine starting control device capable of improving accuracy for estimating the pulse torque of an internal combustion engine and suppressing vibration at an engine start as compared with a conventional technique.SOLUTION: In a starting control device for controlling an electric motor 13 provided drivably with a crankshaft 9 of an internal combustion engine 1A that includes a plurality of cylinders 2, a map showing a relation between a reference torque applied to the crankshaft 9 from each cylinder 2 if a crank angle is 0° at start of cranking and a crank angle θ is stored in a ROM of an ECU 20. In the starting control device, a torque ratio k(θ) is calculated first on the basis of the crank angle at the start of the cranking, and a torque predicted to be applied to the crankshaft 9 from each cylinder 2 during cranking of the internal combustion engine 1A is then calculated on the basis of the map and the torque ratio k(θ). On the basis of the calculated torque, an operation of the electric motor 13 during the cranking of the internal combustion engine 1A is controlled.
