Abstract: The vehicle control device executes: a stop process for stopping fuel supply to two cylinders to be stopped; and a selection process of selecting one cylinder to be a stop instruction for stopping fuel supply from among the cylinders to be stopped. The selection process is a process of selecting a cylinder whose compression top dead center appears earliest among the stop target cylinders.

The stop instruction for the selected cylinder is received before the fuel injection start time and at the stoppable angle interval. The control device executes a retard process of retarding the fuel injection start timing so that the stoppable angle interval includes the fuel injection start timing.

A controller controls a fuel injection amount of the fuel injection valve and an ignition timing of the ignition device. The controller executes a fuel supply process that supplies fuel of the internal combustion engine from the fuel injection valve to the catalyst and a correction process that corrects an amount of fuel supplied to the catalyst during the fuel supply process so that the catalyst is supplied with less fuel when the ignition timing is retarded than when the ignition timing is advanced.

Abstract: An ENG-ECU performs a specific cylinder fuel cutoff process of stopping combustion of an air-fuel mixture in some cylinders out of a plurality of cylinders of an internal combustion engine and a transmission process of transmitting engine operation information on execution of the specific cylinder fuel cutoff process to an HV-ECU. The HV-ECU performs a torque compensation process of compensating for a decrease in engine torque due to execution of the specific cylinder fuel cutoff process using an output torque of a second MG based on the received engine operation information. The ENG-ECU performs a process of starting the specific cylinder fuel cutoff process in a combustion cycle when a waiting time which includes a time until the HV-ECU receives the engine operation information has elapsed after the transmission process has been performed.

Abstract: A controller and a control method for a hybrid electric vehicle are provided. An internal combustion engine and a first rotating electric machine are capable of applying power to a driven wheel via a power split device. A deactivating process deactivates combustion control in a deactivated cylinder that corresponds to one or more of cylinders of the internal combustion engine. A first compensation process sets, when the deactivating process is executed, torque of the first rotating electric machine to be larger than torque of the first rotating electric machine obtained prior to starting the deactivating process so as to compensate for at least some of a decrease amount of torque of the internal combustion engine resulting from the deactivating process.

Abstract: When a temperature increasing process is performed, a CPU sets a target temperature of a catalyst to be lower when a coolant temperature is low than when the coolant temperature is high. The CPU decreases an increase coefficient of fuel in the temperature increasing process when a value obtained by subtracting an estimated value of a temperature of the catalyst from the target temperature is equal to or less than a first prescribed value.

The internal combustion engine can execute port injection and direct injection and can execute a deactivating process that stops supplying fuel to at least one of cylinders and supplies fuel to the remaining cylinders. The controller is configured to execute, when terminating the deactivating process to restart supplying fuel to a deactivated cylinder in which supply of fuel is stopped, a retarding process that executes a first fuel injection through the direct injection and retards a fuel injection start timing as compared to when executing the port injection.

The internal combustion engine may execute multi-shot injection and single-shot injection and execute a deactivating process that stops supplying fuel to at least one of cylinders and supplies fuel to the remaining cylinders.

Abstract: A controller for a vehicle is provided. An air supply passage is connected to a portion upstream of a filter in an exhaust passage. An air supplying process supplies air to the filter through an air supply passage by driving an air pump. An oxygen supplying process supplies oxygen to the filter through the exhaust passage, the oxygen having been passed through a combustion chamber of an internal combustion engine. A reducing process sets an air supply amount per unit time in the air supplying process obtained when the oxygen supplying process and the air supplying process are simultaneously executed to be lower than the air supply amount per unit time in the air supplying process obtained when the oxygen supplying process and the air supplying process are not simultaneously executed.

Abstract: A CPU prompts a user to drive a vehicle to a repair shop by operating a display when an amount of PM deposited in a GPF increases. When a regeneration request for the GPF is input from a shop-side terminal in the repair shop, the CPU performs a regeneration process in a state in which the vehicle stops. The CPU controls a temperature of the GPF such that the temperature at the time of execution of the regeneration process becomes lower when an opening/closing member is in a closed state than when the opening/closing member is in an open state.

Abstract: A control device is capable of executing: an ignition time calculation process of calculating a target ignition time of an ignition plug; a stop process of stopping combustion control for some cylinders of a plurality of cylinders; and a compensation process of controlling a motor generator during the stop process, such that the motor generator compensates a drive power that is lost due to the stop of the combustion control. The control device prohibits the execution of the stop process when the target ignition time calculated in the ignition time calculation process is on a retard side of a predetermined prescribed time.

Abstract: A control device and a control method for a multi-cylinder internal combustion engine including a post-processing device are provided. The control device includes an electronic control unit executing a temperature raising process of raising the temperature of the post-processing device and a recovery-time process. The temperature raising process includes a stopping process and a rich process. In the stopping process, supply of fuel to several of cylinders is stopped. In the rich process, the air-fuel ratio of an air-fuel mixture for different ones of the cylinders other than the several cylinders is made lower than the stoichiometric air-fuel ratio. In the recovery-time process, the concentration of unburned fuel in exhaust gas discharged to the exhaust passage is made higher than an equivalent concentration, when the temperature raising process is stopped. The equivalent concentration is the concentration of unburned fuel being just enough to react with oxygen in the exhaust gas.

Abstract: When an amount of particulate matter (PM) collected by a gasoline particulate filter (GPF) reaches a predetermined amount, a central processing unit (CPU) executes a regeneration process for regenerating the GPF. That is, the CPU stops supply of fuel to any one of cylinders #1 to #4, while increasing an amount of fuel supplied to remaining cylinders. When a temperature of a three-way catalyst becomes equal to or higher than a first temperature, the CPU increases an injection amount to lower a temperature of exhaust gas. When the temperature of the three-way catalyst becomes equal to or higher than the first temperature during the execution of the regeneration process, the CPU does not increase the injection amount.

Abstract: A controller executes a fuel introduction process when stopping combustion in a cylinder under a situation in which a crankshaft is rotating. The fuel introduction process causes a fuel injection valve to inject fuel and causes the fuel to flow out unburned from inside the cylinder to an exhaust passage. The opening degree of an exhaust gas recirculation valve at a point in time when a state in which the execution condition of the fuel introduction process is not satisfied is switched to a state in which the execution condition of the fuel introduction process is satisfied is a preliminary opening degree. During the execution of the fuel introduction process, the recirculation valve controlling section causes the opening degree of the exhaust gas recirculation valve to be smaller than the preliminary opening degree.
