摘要： A controller is configured to control a vehicle that includes an internal combustion engine and an automatic transmission. The controller is configured to execute a shifting process that switches a gear ratio of the automatic transmission and a lean operation process that operates the internal combustion engine with an air-fuel ratio of the air-fuel mixture in a cylinder leaner than a stoichiometric air-fuel ratio. The controller is further configured to, when executing the shifting process during execution of the lean operation process, set an air-fuel ratio in a case in which the shifting process is being executed to a value closer to the stoichiometric air-fuel ratio than an air-fuel ratio in a case in which the shifting process is not being executed.

摘要： A vehicle control apparatus for a vehicle includes a catalyst deterioration diagnosing unit, an engine controlling unit, and a diagnosis start determining unit. The catalyst deterioration diagnosing unit executes a deterioration diagnosis of a catalyst included in an exhaust system of an engine provided in the vehicle. The engine controlling unit controls an air-fuel ratio of the engine to a lean side and thereafter to a rich side during the deterioration diagnosis of the catalyst. The diagnosis start determining unit prohibits the deterioration diagnosis of the catalyst from being executed when a deceleration rate upon deceleration of the vehicle is high, and permits the deterioration diagnosis of the catalyst to be executed when the deceleration rate upon deceleration of the vehicle is low.

摘要： A control device causes the engine to start with a throttle valve being set to a first throttle position when required power required in an engine is smaller than a first threshold value and a detected fuel pressure detected by a low-pressure fuel sensor is lower than a second threshold value. The control device causes the engine to start with the throttle valve being set to a position larger than the first throttle position when the required power is smaller than the first threshold value and the detected fuel pressure is higher than the second threshold value. With this structure, a control device for a vehicle can be provided which allows intermittent operation of the engine with reduced variation in air-fuel ratio.

摘要： An electronic control unit included in a control system is configured to execute a change of a combustion mode in an inertia-phase period during a gear shift operation, or after the gear shift operation is completed, when a request for the change of the combustion mode and a request for a gear shift of the transmission mechanism overlap. The electronic control unit is configured to execute the change of the combustion mode in the inertia-phase period during the gear shift operation when conditions i) and ii) are established, and execute the change of the combustion mode after the gear shift operation is completed when conditions i) and iii) are established. The aforementioned conditions include: i) the change of the combustion mode is accompanied by an increase in engine power; ii) the power running mode is executed during the gear shift operation; and iii) the regeneration mode is executed during the gear shift operation.
