    Abstract: Provided are a method and device for determining a non-line of sight (NLOS) state around a GPS receiver. The method may include collecting, from at least one satellite, satellite information including a direction angle, a signal to noise (SNR), and an altitude, selecting a satellite of which the NLOS state is to be determined based on an altitude value of the collected satellite information, and determining whether the selected satellite is in the NLOS state with respect to a direction to the satellite based on the SNR and direction angle included in the satellite information of the selected satellite. According to the present invention, by reducing a location calculation error that occurs due to a distance measurement error when a location is measured, a more precise result of location measurement can be obtained.

    Abstract: Disclosed herein are a cooperative driving method based on driving negotiation and an apparatus for the same. The cooperative driving method is performed by a cooperative driving apparatus for cooperative driving based on driving negotiation, and includes determining whether cooperative driving is possible in consideration of a driving mission of a requesting vehicle that requests cooperative driving with neighboring vehicles, when it is determined that cooperative driving is possible, setting a responding vehicle from which cooperative driving is to be requested among the neighboring vehicles, performing driving negotiation between the requesting vehicle and the responding vehicle based on a driving negotiation protocol, and when the driving negotiation is completed, performing cooperative driving by providing driving guidance information for vehicle control to at least one of the requesting vehicle and the responding vehicle.

    Abstract: In a vehicle communication environment, a handover apparatus that is located at a random vehicle determines whether to perform handover based on a received signal intensity value of a signal that is received from base stations that are installed at the roadside and information that is acquired from peripheral vehicles. In this case, it is determined whether to perform handover using a signal intensity value and a link base station value representing a base station to which each vehicle is connected among information that is acquired from peripheral vehicles.
