Abstract: In a control device of a hybrid vehicle including an engine and an electric motor serving as drive power sources and a damper device disposed between the engine and the electric motor and having rotational characteristics related to an input torque, the control device comprises: a damper rotational characteristic detecting portion configured to measure a rotational characteristic value of the damper device by allowing the electric motor to input a torque to the damper device while rotation of a crankshaft of the engine is stopped; and an output torque correction control portion configured to control an output torque of the engine or the electric motor to suppress occurrence of vibration based on a difference between the rotational characteristic value of the damper device detected by the damper rotational characteristic detecting portion and a preset initial setting value of the rotational characteristic value of the damper device.

Abstract: A hybrid vehicle 1 includes an internal combustion engine 10 and electric motors 12 and 14 as electric power sources. The hybrid vehicle 1 further includes an electric supercharger 54, a battery 20, and a controller 30. The controller determines whether or not it is necessary to increase a total electric power supply amount to the electric motor and the electric supercharger from the battery based on a state of charge of the battery, and when it is determined that it is necessary to increase the total electric power supply amount from the battery, electric power supply promotion control is performed to increase the total electric power supply amount from the battery. In the electric power supply promotion control, the controller controls the electric power supply amount to the electric motors and the electric supercharger so as to maximize fuel save rate, which is the percentage of decrease of the fuel consumption of an internal combustion engine relative to an increase in the total electric power supply amount from the battery.

Abstract: An action of injection of the main injection fuel (QM) from the fuel injector (3) is started within a range of crank angle from 10 degree before the compression top dead center to 10 degree after the compression top dead center. A smaller amount of the auxiliary injection fuel (QN) than the main injection fuel (QM) is made to be injected from the fuel injector (3) before the main injection fuel (QM) so as to make the auxiliary injection fuel (QN) ignite by the premixed charge compression ignition. The injection timing of the auxiliary injection fuel (QN) is controlled to a timing whereby a heat generated by the premixed charge compression ignition of the auxiliary injection fuel (QN) causes the premixed charge compression ignition of the main injection fuel (QM) after the start of injection of the main injection fuel (QM).

Abstract: A turbocharger that includes a turbine and a compressor, an electric supercharger that is arranged in an intake passage, and a control device that increases a rotational speed of the electric supercharger upon receipt of a torque increase request with respect to the internal combustion engine are provided. During a process in which the rotational speed of the electric supercharger is increasing, if the rotational speed arrives at a predetermined switching rotational speed “Ntec”, the control device decreases a rate of increase in the rotational speed from a first rate of increase “Nteup1” to a second rate of increase “Nteup2” (

Abstract: A learning use data set showing relationships among an engine speed, an engine load rate, an air-fuel ratio of the engine, an ignition timing of the engine, an HC or CO concentration of exhaust gas flowing into an exhaust purification catalyst and a temperature of the exhaust purification catalyst is acquired. The acquired engine speed, engine load rate, air-fuel ratio of the engine, ignition timing of the engine, and HC or CO concentration of the exhaust gas flowing into the exhaust purification catalyst are used as input parameters of a neural network and the acquired temperature of the exhaust purification catalyst is used as training data to learn a weight of the neural network. The learned neural network is used to estimate the temperature of the exhaust purification catalyst.

Abstract: A control system is applied to an internal combustion engine. The internal combustion engine includes an electric compressor provided in an intake passage, a bypass passage which bypasses the electric compressor, a low pressure EGR passage which connects a section of the intake passage, which is positioned upstream more than the electric compressor, and an exhaust passage, and a low pressure EGR valve provided in the low pressure EGR passage. An ECU, when a predetermined pressure accumulation condition where a gas flow rate of a specific place of the intake passage has become equal to or less than a predetermined amount, is satisfied, first executes a pressure accumulation control where the bypass valve is closed and the electric compressor is activated, and then, when an opening condition is satisfied during an execution of the pressure accumulation control, opens the low pressure EGR valve and opens the bypass valve.
