  • Patent number: 12679339
    Abstract: A parking method includes searching a moving path of a trailer, giving a movement instruction to a vehicle, based on the moving path of the trailer, measuring one or both of a current location of the trailer and a current direction of the trailer according to the movement instruction, comparing one or both of a desired location of the trailer and a desired direction of the trailer in the moving path of the trailer with one or both of the current location of the trailer and the current direction of the trailer; and moving the trailer to a parking space, based on a result of the comparing.

  • Patent number: 12128949
    Abstract: A vehicle control method and apparatus to reverse a trailer are provided. The method includes storing a moving path of a trailer connected to the vehicle by a hitch, measuring a location of the trailer or a heading of the trailer when the trailer is reversed upon activation of a reversing mode, comparing the location of the trailer or the heading of the trailer in the stored moving path of the trailer with the measured location of the trailer or the measured heading of the trailer, and minimizing a difference between the location of the trailer in the stored moving path of the trailer and the measured location of the trailer, or a difference between the heading of the trailer in the stored moving path of the trailer and the measured heading of the trailer, and t performing an operation of reversing the trailer.

  • Patent number: 11238739
    Abstract: An apparatus configured to prevent at least one vulnerable road user (VRU) from having an accident including a driver monitoring unit configured to utilize at least one sensor provided in a vehicle to detect a gaze area corresponding to a gaze direction of a driver of the vehicle, a VRU monitoring unit configured to calculate position information including current position and predicted motion information of the VRU existing in a peripheral area of the vehicle, the VRU is detected by using the at least one sensor, a detection unit configured to detect whether the driver is aware of the VRU and whether the VRU is aware of the driver based on a gaze area of the driver and the position information of the VRU, and a warning processing unit configured to output warning information on a dangerous situation to some or all of the driver and the VRU in response to a detection result of the detection unit.

  • Patent number: 7927394
    Abstract: Collection apparatus are installed in a horizontal separator vessel to aid conventional coalescing media to remove mist and droplets from a gas flow, typically downstream from a compressor. The collection apparatus have filaments which act to wick the coalesced droplets either from the conventional coalescing media or from the sides of the vessel toward an annular channel which collects the droplets and assists in delivering the droplets, by gravity, to the bottom of horizontal vessel where they are carried to a collection area. Use of the collection apparatus permits a reduction in the size of the separator vessel and further permits vapor load factors of up to about 10 times that in a conventionally designed separator vessel.

  • Publication number: 20070045012
    Abstract: A surface vehicle capable of overcoming obstacles is disclosed in which the vehicle accelerates vertically while having a horizontal velocity. The vehicle has a frame and at least three wheels attached to the frame to which a horizontal propulsion system is coupled. Further, a vertical propulsion system is coupled to the frame and the wheels. The vertical propulsion system is capable of providing a force to such wheels normal to the surface so that the vehicle separates from the surface. The vehicle has an electronic control unit coupled to the vertical propulsion system to automatically control its operation.
