  • Patent number: 10337427
    Abstract: A control device for a compression self-ignition combustion engine is provided, which includes a variable valve operating system configured to introduce internal exhaust gas recirculation (EGR) gas into a combustion chamber, a boosting system configured to boost intake air, a controller configured to control the valve operating system, and a sensor connected to the controller and configured to detect a parameter related to an operating state of the engine. An operation mode of the valve operating system is switchable between first and second modes. The boosting system boosts the intake air when an engine load is higher than a given load, and does not boost when lower than the given load. When the engine load is high, the controller controls the valve operating system to operate in the first mode, and when the load is low, the controller controls the valve operating system to operate in the second mode.

  • Patent number: 10246142
    Abstract: A structural member for a vehicle projects from a vehicle body. The structural member includes a first airflow surface and a second airflow surface along each of which airflow flows, and an imaging window. The first airflow surface and the second airflow extend between a front edge and a rear edge of the structural member in a front-rear direction of the vehicle body and face away from each other. The first airflow surface has a length longer than a length of the second airflow surface in the front-rear direction. The imaging window is provided in the first airflow surface, and an image of an area outside the vehicle body is captured through the imaging window.

  • Patent number: 9676369
    Abstract: A vehicle wiper device includes: a first blade having an operating range that includes an upper mid region of a vehicle windshield; a second blade having an operating range that includes a lower region of the operating range of the first blade; a blade driving unit that causes each blade to reciprocate; and a controller that controls operation of the blade driving unit. When a tip end of the second blade moves in a special control region that is oriented toward a specific region preliminarily specified in the upper mid region, the controller controls the blade driving unit such that a moving speed of the second blade is lower than a moving speed of the second blade when moving in another region.

  • Patent number: 9527481
    Abstract: A vehicle wiper device includes: a first blade having an operating range that includes an upper mid region of a vehicle windshield; a second blade having an operating range that includes a lower region of the operating range of the first blade; a cleaning-liquid feeding unit; a blade driving unit that causes each blade to reciprocate; and a controller that controls operation of the cleaning-liquid feeding unit and operation of the blade driving unit. The controller performs the control such that, after a series of normal operation in which the first blade and the second blade reciprocate while ejecting the cleaning liquid has been completed, additional movement operation is performed in a state where feeding of the cleaning liquid from the cleaning-liquid feeding unit is stopped.
