Title:
VEHICLE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2016180363
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vehicle control device which can suppress an increase of a fuel consumption amount of an engine which can perform a cylinder pause operation.SOLUTION: A vehicle control device comprises an engine which can perform a full-cylinder operation for performing a cylinder pause operation for pausing combustion by a part of cylinders, and performing combustion by all the cylinders, and a control part which control the engine. The control part starts the cylinder pause operation when the power of the engine becomes lower than prescribed power, estimates an integrated value of a fuel consumption amount while continuing the cylinder pause operation in the case that it is assumed that an operation is switched to a full-cylinder operation at a time point when the power reaches the prescribed power while continuing the cylinder pause operation (step S40) when the power reaches the prescribed power or larger (step S20-Y) during the execution of the cylinder pause operation (step S10-Y), and switches the operation to the full-cylinder operation (step S60) when a difference between the integrated value of the fuel consumption amount by the cylinder pause operation after the power reaches the prescribed power and an estimation value reaches a prescribed amount or larger(step S50-Y).SELECTED DRAWING: Figure 8
