  • Patent number: 10703367
    Abstract: According to one embodiment, acceleration and deceleration profiles can be generated and applied dynamically when a condition exist necessitating a change in the velocity of an autonomously controlled vehicle. An acceleration or deceleration profile can be generated when conditions exist necessitating a change in velocity and according to a smoothing function and based on a set of control parameters such as a target velocity, a determined time to reach the target velocity, and a maximum rate of change for the velocity of the vehicle. The smoothing function can be non-linear and can produce a profile representing a curve having a lower rate of change in the velocity of the vehicle at a beginning and an end of the curve than in a middle of the curve. In this way, changes in velocity can be more gradual at a beginning and end of the change and more aggressive in the middle.

  • Patent number: 9389141
    Abstract: An estimation device for a cylinder intake air amount in an internal combustion engine can make calculations in real time with a high accuracy in a small number of adaptation constants. The device includes an AFS, a volumetric efficiency corresponding value calculation unit that calculates a volumetric efficiency correction factor which is an index indicating an amount of air entering a cylinder, a physical model that models a response delay of an intake system, and a unit that calculates a cylinder intake air amount actually sucked into the cylinder by using the amount of intake air, the volumetric efficiency correction factor and the physical model. The volumetric efficiency correction factor required for calculating the amount of air sucked into the cylinder by a response delay model of the intake system is calculated by using the intake air amount, an intake manifold density, and an intake manifold density change amount.

  • Patent number: 9322349
    Abstract: There is provided an internal combustion engine control apparatus that can more accurately calculate a volume efficiency correction coefficient and can more accurately estimate the amount of air that flows into a cylinder and the external exhaust gas recirculation amount. In an internal combustion engine provided with an exhaust gas recirculation apparatus including an exhaust gas recirculation valve and an exhaust gas recirculation path, based on a cylinder flow rate, an exhaust gas recirculation amount, an inner-intake-pipe density, and an inner-intake-pipe density changing amount, a volume efficiency correction coefficient, as a volume efficiency corresponding value, is calculated; then, by use of the calculated volume efficiency correction coefficient, a cylinder intake air amount and a recirculation amount of exhaust gas that is taken into the cylinder are calculated.

    Abstract: Methods and systems for minimizing the power consumed by a supercharger pump in an engine system. The methods and systems minimize the delta pressure across the pump with a control strategy for positioning the electronic throttle and supercharger bypass valve in a coordinated manner to deliver the required amount of fresh air flow into engine (i.e., the air flow associated with the driver's requested torque), while, at the same time, minimizing the power consumed by the supercharger pump for best fuel economy.

  • Patent number: 9261031
    Abstract: Provided is a control device for an internal combustion engine, capable of controlling acceleration-response characteristics, performing an operation at an optimal fuel-efficiency point, and learning variation factors in an internal combustion engine provided with a supercharger including a wastegate valve. A target throttle-valve upstream pressure is calculated based on a target charging efficiency and a rotation speed. An exhaust-gas flow rate is calculated based on an air/fuel ratio and an intake-airflow rate. A target compressor driving force is calculated based on a target intake-airflow rate and a target throttle-valve upstream pressure. A wastegate-valve control value is calculated from the exhaust-gas flow rate and the target compressor driving force by using the relationship in which the relation expression expressing the characteristics of the exhaust-gas flow rate and the target compressor driving force depends only on the wastegate-valve control value.

  • Patent number: 9249764
    Abstract: A system for a vehicle includes a humidity determination module, a specific humidity module, and a parameter control module. The humidity determination module determines a first specific humidity of air based on a relative humidity of the air measured by a humidity sensor in an intake system of the vehicle. The specific humidity module sets a second specific humidity of the air equal to one of the first specific humidity and a predetermined specific humidity of the air in response to a comparison of a mass air flowrate (MAF) into an engine and a predetermined flowrate. The parameter control module controls at least one operating parameter of an engine based on the second specific humidity.

  • Patent number: 9228519
    Abstract: An estimation device for a cylinder intake air amount in an internal combustion engine can estimate a cylinder intake air amount to a sufficient accuracy for suitable engine control, in either of steady state operation and transient operation with a small number of adaptation constants and a small amount of calculation load, without requiring a huge memory capacity. The relation between an opening degree and an effective opening area of a throttle valve has been learned, while calculating the cylinder intake air amount in an S/D method from a volumetric efficiency correction factor map adapted by valve timing at the time of steady state operation, and in a period from a transient change until an exhaust manifold temperature is converged, an intake air amount is calculated based on the relation thus learned. The cylinder intake air amount is calculated based on a physical model of an intake system response delay.

  • Publication number: 20150144114
    Abstract: An object of the present invention is to enable monitoring whether a target throttle opening degree to be given to an electronically controlled throttle is not out of an appropriate range, in a controller for an internal combustion engine with a supercharger. To this end, in a controller according to the present invention, propriety of the target throttle opening degree is confirmed with a reference throttle opening degree as a reference by a monitoring device. The target throttle opening degree is calculated based on a target intake air quantity and a measured value or an estimated value of a supercharging pressure by using an inverse model of an air model expressing a dynamic relation that is established among the supercharging pressure, a throttle opening degree and an intake air quantity, by a first arithmetic unit.

  • Publication number: 20150122234
    Abstract: An object of the present invention is to detect abnormality of a supercharging pressure sensor accurately in an internal combustion engine equipped with a supercharger that can change a supercharging pressure by operation of an actuator. For this purpose, a control device according to the present invention operates an actuator so that a supercharging pressure measured by a supercharging pressure sensor becomes a target supercharging pressure, acquires a measured value of a flow rate of air flowing in an intake passage, and calculates an estimated supercharging pressure based on the measured air flow rate. The control device according to the present invention sets a first abnormality flag when a first simultaneous inequality is established, which is a simultaneous inequality evaluating magnitude correlation between the measured supercharging pressure, the target supercharging pressure and the estimated supercharging pressure, and is not established when the supercharging pressure sensor is normal.
