  • Publication number: 20210276560
    Abstract: A vehicle control device includes an external environment recognition unit that recognizes a situation of a surrounding periphery of a user's own vehicle, and a lane change control unit that executes an automatic lane change by controlling a travel speed and steering of the user's own vehicle based on a recognition result of the external environment recognition unit. The automatic lane change includes a first lane change (third mode) which is executed regardless of an intention of a driver, and a second lane change (first mode) which is executed in accordance with the intention of the driver. In the case that a request to make the second lane change is detected during execution of the first lane change, the lane change control unit switches the automatic lane change to be executed from the first lane change to the second lane change.

  • Publication number: 20200149368
    Abstract: An object of the present invention is to provide a well plugging apparatus configured to reduce an expense and shorten a process for well drilling and a temporal plugging method of a well using the well plugging apparatus. The well plugging apparatus according to the present invention is a well plugging apparatus that includes a downhole plug, a setting tool (2) to operate and install the downhole plug, and an obstacle that plugs a flow path in the downhole plug. Since the setting tool (2) internally includes the obstacle, after the downhole plug is installed inside the well, and the setting tool (2) is removed, the flow path in the downhole plug can be reliably plugged in a short time. Additionally, the use of the well plugging apparatus of the present invention allows temporarily plugging the well reliably in a short time.
