  • Controller and control method for internal combustion engine
    Patent number: 11965444
    Abstract: A controller for an internal combustion engine is configured to execute a determination process that determines that a deviation between a first change amount and a second change amount during a fuel cutoff operation is less than or equal to a threshold, and an anomaly diagnosing process that determines that an exhaust purification device is in a detached state when the determination process determines that the deviation is less than or equal to the threshold. The first change amount and the second change amount are change amounts per unit time of the temperature of exhaust gas on the upstream side and the downstream side of the exhaust purification device, respectively. The controller is configured to interrupt the determination process when the upstream-side temperature increases within a determination period.

  • Controller and control method for internal combustion engine
    Patent number: 11965473
    Abstract: An internal combustion engine includes a port injection valve, a direct injection valve, and a forced-induction device. A ratio of an amount of fuel injected from the port injection valve with respect to a total amount of fuel supplied for one fuel combustion in the cylinder is defined as a port injection ratio. The internal combustion engine is controlled such that, in a case in which a condition is satisfied that the forced-induction device is in an operation of performing forced induction and the internal combustion engine is in an engine operation region in which a valve overlap period is greater than zero, the port injection ratio is set to be small and a start timing of fuel injection from the port injection valve is delayed as compared with a case in which the condition is not satisfied.

  • Vehicle control system, vehicle control method, and storage medium
    Patent number: 11965468
    Abstract: A vehicle control system, a vehicle control method, and a storage medium are provided. A stopping process stops fuel supply to one or more stopping cylinders and supplies fuel to one or more remaining cylinders during a load operation of an engine. During execution of the stopping process, a compensating process compensates for a decrease in output of the one or more stopping cylinders due to the execution of the stopping process by increasing output generated by combustion in the one or more remaining cylinders. The system control circuit causes, when the engine rotation speed of the engine is the same, the output after being increased by the compensating process to decrease as a shaft torque of the crankshaft of the engine increases.

  • Control apparatus for vehicle, control method for, and control system for vehicle
    Patent number: 11964534
    Abstract: A control apparatus for a vehicle disclosed herein is applied to a vehicle configured to perform pre-air conditioning of the interior of the vehicle by starting an internal combustion engine according to a remote control signal sent from a remote controller. When starting pre-air conditioning according to the remote control signal, the control apparatus sets the control mode of the vehicle to a drive-disabling mode, which is a control mode that disables an operation for driving the vehicle. If a specific mode-cancelling operation is detected in a situation in which the remote controller is present in the interior of the vehicle while the control mode of the vehicle is being set to the drive-disabling mode, the control apparatus cancels the drive-disabling mode while leaving the internal combustion engine operating.
