  • Patent number: 10683822
    Abstract: In certain embodiments, a method and an apparatus which can be implemented with a simplified and inexpensive configuration without causing a misfire in a combustion state. In a fuel-Cetane-number estimation method according to embodiments, a map which specifies a relationship between the Cetane number and a control parameter at which NOx concentration of exhaust gas reaches a predetermined value is prepared in advance. Then, the control parameter is controlled variably to detect transition of the NOx concentration of the exhaust gas of the internal combustion engine, and thereby the control parameter of the internal combustion engine at which the NOx concentration has reached the predetermined value is obtained, and the Cetane number which corresponds to the obtained control parameter is estimated on the basis of the map.

  • Publication number: 20200164842
    Abstract: A braking control device comprises: an operational displacement sensor detecting operational displacement of a braking member; a first hydraulic pressure unit that reads operational displacement as a first displacement processing value via a first displacement signal line and adjusts braking hydraulic pressure based on the first displacement processing value; a second hydraulic pressure unit that reads operational displacement as a second displacement processing value via a second displacement signal line and adjusts braking hydraulic pressure based on the second displacement processing value; and a communication bus transmitting signals between the first and second hydraulic pressure units. The first hydraulic pressure unit acquires the second displacement processing value via the communication bus and determines suitability/unsuitability of the first displacement processing value.

  • Patent number: 10559071
    Abstract: An image processing apparatus includes a correcting unit and a pasting unit. The correcting unit corrects a dynamic range of a second image in accordance with pixel information of a region. The second image is pasted on a first image serving as a destination for pasting. The region is in the first image and is to be in contact with the second image. The pasting unit pastes the second image on the first image after the correction of the dynamic range. The second image has pixel information. The pixel information is corrected in such a manner that a boundary with the first image is inconspicuously viewed.

  • Publication number: 20200039494
    Abstract: A braking device includes a stroke simulator, a hydraulic pressure generation unit, a reaction hydraulic pressure detection unit, a master hydraulic pressure detection unit, and a bottoming determination unit. The stroke simulator includes a cylinder and a piston slidably movable inside the cylinder in conjunction with an operation of a brake operation member. The stroke simulator causes a reaction force chamber to generate a reaction hydraulic pressure and applies a reaction force. The hydraulic pressure generation unit generates a master hydraulic pressure by driving a master piston and supplies a hydraulic pressure to a wheel cylinder. The reaction hydraulic pressure detection unit detects the reaction hydraulic pressure. The master hydraulic pressure detection unit detects the master hydraulic pressure. The bottoming determination unit determines whether the master piston is in a bottoming state based on the reaction hydraulic pressure and the master hydraulic pressure.

  • Publication number: 20200039490
    Abstract: The vehicular brake device includes a determination unit, a ratio setting unit, and the control unit. The determination unit determines the operating condition of a vehicular brake device. The ratio setting unit sets, on the basis of the result of determination by the determination unit, a first ratio which is the ratio of a wheel pressure generated by a piston drive unit to a target wheel pressure, and a second ratio which is the ratio of a wheel pressure generated by a hydraulic pressure adjusting unit to the target wheel pressure. The control unit controls the piston drive unit and the hydraulic pressure adjusting unit on the basis of the first ratio and the second ratio.

  • Publication number: 20190381978
    Abstract: This vehicle control system is provided with an input monitoring unit and a determination time changing unit. When a state in which first target data is not input to a second control unit continues for a first determination time or longer, the input monitoring unit determines the first target data to be in a non-input state. When a state in which second target data is not input to the second control unit continues for a second determination time or longer, the input monitoring unit determines the second target data to be in a non-input state. When the first target data is determined to be in a non-input state, the determination time changing unit shortens the second determination time.

  • Patent number: 10452901
    Abstract: An image processing device combines an image of a medium exposed to visible light and an image of the medium exposed to ultraviolet light so that parts printed with UV ink can be easily identified. A control device (image processing device) has an image acquisition unit that drives an image sensor and acquires a first image by imaging the face of a check when exposed to a visible first light, and acquires a second image by imaging the face of the check when exposed to an ultraviolet second light; a reverse image generating unit that generates a reversed second image by reversing light and dark in the second image; and a second synthesizing unit that generates a second synthesized image by combining the first image and the reversed second image. Because the reversed second image that is the reverse of the second image becomes an image that is light overall, a drop in the luminance and a drop in the contrast of the first synthesized image can be suppressed, and parts printed with UV ink are easily discerned.
