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.

The superheated steam generating pipe (20, 40) is formed of a material capable of generating heat by energization, and has a flow path (200, 400) through which exhaust gas can flow, and moisture contained in the exhaust gas flowing through the flow path is converted into superheated steam by the heat. The housing (10) is provided to accommodate the superheated steam generating pipe, is formed to allow the exhaust gas before being introduced into the flow path to flow therethrough and can preheat the exhaust gas by the heat of the superheated steam generating pipe.

摘要： A method for controlling exhaust gas emission of a motor vehicle may include determining when the motor vehicle drives into a low-emission zone, wherein the low-emission zone dictates a maximum emission level for the motor vehicle; reducing actual accelerator actuation signals of the motor vehicle to effective accelerator actuation signals within the low-emission zone; and trimming an actual intake temperature of the motor vehicle, being measured with an intake temperature sensor of the motor vehicle, to an effective intake temperature when the actual intake temperature falls outside a predetermined temperature range within the low-emission zone; wherein at least one of the effective accelerator signals and the effective intake temperature are used as inputs for controlling an exhaust gas recirculation (EGR) subsystem of the motor vehicle.

摘要： A catalyst temperature estimation device that estimates a temperature of a catalyst provided in an exhaust passage of an internal combustion engine includes a storage device and processing circuitry. The storage device stores mapping data that specifies a mapping that uses multiple input variables to output an estimation value of the temperature of the catalyst. The multiple input variables include at least one variable of an ambient temperature variable or an excess amount variable. The multiple input variables further include a fluid energy variable, which is a state variable related to energy of fluid flowing into the catalyst, and a previous cycle value of the estimation value of the temperature of the catalyst. The processing circuitry is configured to execute an acquisition process, a temperature calculation process, and an operation process. The mapping data includes data that is learned through machine learning.

摘要： A method for controlling an internal combustion engine system including a catalyst includes receiving a desired output for an internal combustion engine, and receiving sensor information including information indicative of a temperature of the catalyst. The method includes calculating a plurality of sets of engine performance values based on respective sets of candidate control points, the engine performance values including a temperature change rate at which the temperature of the catalyst changes over time, and determining whether the temperature change rate satisfies a minimum warmup rate for the catalyst. The method also includes controlling the internal combustion engine based on a selected set of candidate control points and the minimum warmup rate.
