Vehicle control device

Japanese Patent JP6354536

B2

PROBLEM TO BE SOLVED: To provide a control device for a vehicle capable of properly determining abnormality in fuel injection.SOLUTION: An ECU 20 calculates excess or deficiency of output torque of its own cylinder to a target torque of every cylinder on the basis of a rotating speed NE of each cylinder, and implements torque control for increasing or decreasing correction of a fuel injection amount corresponding to the excess or deficiency in fuel injection of a next combustion cylinder. Further fuel cut is released when the rotating speed NE is lowered to a prescribed recovery rotating speed after implementing the fuel cut of an engine 10 under a decelerating state of a vehicle. In a state that the increasing or decreasing correction of the fuel injection amount by the torque control after releasing the fuel cut during a period when a decelerating state is finished after the start of deceleration of the vehicle, difference between rotating speeds ΔNE between a latter cylinder and a former cylinder of two cylinders of which combustion orders are continued, is calculated, and abnormality in fuel injection of the cylinder of former combustion is determined when the difference in rotating speed ΔNE is larger than a first threshold value or smaller than a second threshold value.SELECTED DRAWING: Figure 5
