  • Publication number: 20210362856
    Abstract: An on-vehicle aircraft control system includes a winding device provided on a landing platform, a connecting member connecting the winding device and an aircraft and wound up or drawn out by the winding device, and a controller controlling the winding device and the aircraft. Upon receipt of a landing request to land the aircraft on the landing platform, the controller winds up the connecting member by the winding device and controls an attitude of the aircraft so as to land the aircraft with a photographing unit provided on the aircraft facing in a specified photographing direction determined in advance.

  • Publication number: 20210282989
    Abstract: The wheelchair includes a seating portion, body frames that support the seating portion, wheels that are rotatably supported by the body frames, an engaging portion, a left brake that brakes a left rear wheel, and a coupling portion that couples the engaging portion and the left brake to each other. The engaging portion is capable of switching between an engagement attitude for engaging a vehicle body member that forms an opening of a vehicle and a disengagement attitude for releasing the engagement with the vehicle body member. The coupling portion transmits the movement of the engaging portion to the left brake when the engaging portion makes an attitude change from the disengagement attitude to the engagement attitude. This operates the left brake when the attitude of the engaging portion switches from the disengagement attitude to the engagement attitude and brakes the left rear wheel.

  • Patent number: 10814908
    Abstract: A lane keeping control device performs lane keeping control to allow a host vehicle (V) to travel in a travel lane (21) in which the host vehicle is currently traveling. The lane keeping control device continues to perform the lane keeping control such that the host vehicle travels toward a branch road (30) ahead, when the branch road (30) has been detected, and a turn signal (WL) has been activated to indicate a direction toward the branch road (30).

  • Patent number: 10266204
    Abstract: A lane-maintaining control device detects a lane width (H1) of a traveling lane (21) through a camera (4) and performs lane-maintaining control without a deviation from the lane width (H1). When detecting, through the camera (4), that the traveling lane (21) gradually increases (H2>H1 where the increasing lane width is (H2)), the lane-maintaining control device continues the lane-maintaining control on a condition that a turn signal is not operated.

  • Patent number: 10037692
    Abstract: A traffic sign recognition system includes a display for displaying caution information regarding a traffic sign ahead of a vehicle, and a processor configured to execute a viewing direction detecting module for detecting a viewing direction of a driver, a traffic sign detecting module for detecting the traffic sign, and a road surface condition detecting module for detecting a slippery road surface condition. The processor controls the display to display the caution information regarding the detected traffic sign when the detected viewing direction of the driver is different from a direction of the detected traffic sign, and controlling the display to refrain from displaying the caution information when the detected viewing direction of the driver matches the direction of the detected traffic sign. When the slippery road surface condition is detected, the processor controls the display to display the caution information regardless of the viewing direction of the driver.

  • Publication number: 20120111143
    Abstract: In a crankshaft of an internal combustion engine wherein a crankthrow is shortened by the use of a multi-link mechanism, the crankthrow from the axis of a main journal to the axis of a crankpin is set shorter than one-half of a piston stroke, and an oil passage is formed to supply lubricating oil to a bearing portion of the crankpin. The pin-side opening of the oil passage, which is open at the outer peripheral surface of the crankpin, is formed in ranges other than angular ranges of 0°, 90°, 180°, and 270° with respect to a reference line extending from the axis of the main journal toward the axis of the crankpin in a decentering direction of the crankpin, thereby alleviating a stress concentration caused by a torsional torque in the vicinity of the pin-side opening of the oil passage.
