A supercharged engine includes an engine body, an electric supercharger, a turbocharger, an EGR passage establishing communication between an exhaust passage downstream from a turbine of the turbocharger and an intake passage upstream from a compressor of the turbocharger, a fuel supply unit configured to supply fuel into a cylinder, and a controller configured to open the EGR passage and output a control signal to the electric supercharger to increase a boost pressure of the electric supercharger during acceleration of the vehicle in which an amount of the fuel supplied by the fuel supply unit is increased in response to an acceleration request signal.

Methods and systems are provided for controlling vehicle operating parameters depending on whether the vehicle is operating within an area defined by an adjustable geographical boundary, the adjustable geographical boundary defined based on wireless communication between vehicles and infrastructures. In one example, a method comprises determining that the vehicle has entered into an area defined by the adjustable boundary, and adjusting a control mapping of an acceleration control of the vehicle in response to the determining. In this way, fuel economy, emissions, and customer satisfaction may be improved.

Generally, the current threshold value is set as a fixed value. Therefore, even in a case where an abnormality occurs in the load and the resistance value is small, when the power supply voltage applied to the load is low, the current value is also low, and falls below the threshold value, and there is a possibility that the overcurrent is not detected. In the present invention, by providing a second detection means that detects a load abnormality by calculating the resistance value of the load from information of the power supply voltage applied to the load, in addition to a first detection means that detects an overcurrent state that indicates the load abnormality using only current value information, it is possible to detect an overcurrent indicating an abnormality of the load even when the power supply voltage applied to the load is low.

A control device of an internal combustion engine includes: a parameter value acquiring part acquiring values of input parameters; a computing part utilizing a model using a neural network to calculate a value of an output parameter, and a control part controlling operation of the engine. The model outputs the value of the output parameter from an output layer node if the values of the input parameters are input to the input layer nodes. When an abnormality occurs at values of part of the input parameters among the input parameters, the computing part uses the corrected model to calculate the value of the output parameter, the corrected model being provided by correcting the model so that a value changing in accordance with a value of an abnormal input parameter is not input from a input layer node corresponding to the abnormal input parameter to a hidden layer node.

A method for programming an internal combustion engine control unit includes operating a test internal combustion engine at a first speed and a first torque while simulating a condition of the test internal combustion engine by restricting a flow of air to the test internal combustion engine to simulate altitude variations of the test internal combustion engine or elevating a temperature of the flow of air to simulate ambient temperature variations of the test internal combustion engine. The method also includes measuring engine performance information while operating the test internal combustion engine at the first speed and first torque and while simulating the condition of the test internal combustion engine, and programming the internal combustion engine control unit by storing the measured engine performance information in a memory associated with the internal combustion engine control unit.

In a dither control process performed on a fuel injection valve, at least one cylinder is set as a rich combustion cylinder and another cylinder is set as a lean combustion cylinder. A dither control process is executed in a first mode when a vehicle is driven in a normal manner by a user. The dither control process is executed in a second mode on condition that a command signal for performing a temperature raising process on the exhaust gas purifier is input from a device outside the vehicle at a repair shop. The absolute value of the difference between the air-fuel ratio of the lean combustion cylinder and the air-fuel ratio of the rich combustion cylinder obtained by the dither control process is set to be greater in the second mode than in the first mode.
