  • Publication number: 20210316726
    Abstract: An apparatus and method for controlling a vehicle speed based on information about forward vehicles that travel in the same lane may be acquired using Vehicle to Everything (V2X) communications in a cooperative adaptive cruise control (CACC) system. The CACC system includes a communication unit receiving vehicle information from neighboring vehicles using V2V communications; an information collection unit collecting vehicle information of the neighboring vehicles and the subject vehicle using sensors; and a control unit determining a forward vehicle and a far-forward vehicle using the sensors, selecting first and second target vehicles for being followed by the subject vehicle based on the vehicle information of the forward vehicle and the far-forward vehicle and the vehicle information of the neighboring vehicles, and controlling the driving speed of the subject vehicle based on speed information of the first and second target vehicles.

  • Patent number: 10682599
    Abstract: Provided are filter media for liquid filters and a method of manufacturing the same, in which a thin filter layer is formed and the content of nanofibers weighs light, by laminating a low weight nanofiber web on a porous nonwoven fabric, and thus a less differential pressure is applied before and after filtering, to thereby increase a pass flow rate. The filter medium includes: a porous support that plays a strength support role; and a nanofiber web that is laminated on one side of the porous support and is made of nanofibers of a polymer material, in which the nanofiber web comprises fine pores of a three-dimensional structure, through which a liquid to be treated passes, wherein content of the nanofibers is less than 5 gsm.
