Abstract
Official abstract text for this publication.
A control device of a vehicle including an engine, an electric motor, and a clutch disposed on a power transmission path between the engine and the electric motor, the control device of a vehicle performing an ignition start causing combustion in a cylinder of the engine to rotate the engine at a start of the engine, the control device of a vehicle switching a cylinder in which combustion is first caused in the engine based on an actuation during a rotation stop process of the engine of an exhaust valve in a cylinder stopped in an expansion stroke, when performing the ignition start at the start of the engine.
First claim
Opening claim text (preview).
1 . A control device of a vehicle including an engine, an electric motor, and a clutch disposed on a power transmission path between the engine and the electric motor, the control device of the vehicle performing an ignition start causing combustion in a cylinder of the engine to rotate the engine at a start of the engine, the control device of the vehicle switching a cylinder in which combustion is first caused in the engine based on an actuation during a rotation stop process of the engine of an exhaust valve in a cylinder stopped in an expansion stroke, when performing the ignition start at the start of the engine. 2 . The control device of the vehicle of claim 1 , wherein when the exhaust valve of the cylinder stopped in the expansion stroke is temporarily opened because rotational position of the engine advances beyond a rotation stop state during the rotation stop process of the engine, the control device of the vehicle performs a reversal start causing combustion first in a cylinder stopped in a compression stroke to negatively rotate the engine before causing combustion in the cylinder in the expansion stroke to positively rotate the engine, and wherein when the exhaust valve of the cylinder stopped in the expansion stroke is not temporarily opened, the control device of the vehicle causes combustion first in the cylinder stopped in the expansion stroke to positively rotate the engine. 3 . The control device of the vehicle of claim 2 , wherein fuel is injected to the cylinder in the expansion stroke while the engine is negatively rotating during the reversal start. 4 . The control device of the vehicle of claim 2 , wherein during the reversal start, the cylinder in the expansion stroke is ignited before the cylinder in the expansion stroke reaches a top dead center and when during the reversal start, engine rotation speed in a negative direction is reduced in speed. 5 . The control device of the vehicle of claim 1 , wherein the clutch is controlled toward engagement to increase the engine rotation speed after the engine positively rotates.
