Control device of vehicle

A control device of a vehicle including an internal combustion engine having a plurality of cylinders, the control device comprising a processing circuit,

• wherein the processing circuit is configured such that:
• the processing circuit executes a stop process of stopping a fuel supply to two or more cylinders of the plurality of cylinders and supplying fuel to a remaining one or more cylinders;
• each of the plurality of cylinders repeatedly executes a combustion cycle such that a compression top dead center of the plurality of cylinders sequentially appears, an operation from a start of an expansion stroke to an end of a compression stroke being the combustion cycle;
• and
• the processing circuit executes a selection process before the stop process, one cylinder that is a target of a stop instruction for stopping the fuel supply among stop target cylinders being selected in the selection process, every time the compression top dead center appears in any stop target cylinder in which the fuel supply is stopped;
• the selection process is a process of selecting a cylinder in which a compression top dead center appears earliest among the stop target cylinders at the time of execution of the selection process, a crank angle interval from when the cylinder to be subjected to the stop instruction is selected to when the cylinder to be subjected to the stop instruction is switched to the next cylinder among the stop target cylinders is a stoppable angle interval, and the stop instruction for the selected cylinder is received during the combustion cycle and before a fuel injection start timing and during the stoppable angle interval;
• and
• the processing circuit executes a lag process in which the fuel injection start timing for the selected stop target cylinder is retarded relative to the compression top dead center of the selected stop target cylinder such that the stoppable angle interval includes the fuel injection start timing.
