Disclosed herein are an apparatus and method for detecting an obstacle adaptively to vehicle speed. The apparatus includes a control unit, a speed-adaptive camera sensor, a speed-adaptive laser scanner sensor, and a detection data integration unit. The control unit receives information about the speed of a vehicle and a Pulse Per Second (PPS) signal from a Global Positioning System (GPS) module. The speed-adaptive camera sensor adjusts the range of a detection region based on the information about the speed of the vehicle, and generates first detection data on an object. The speed-adaptive laser scanner sensor adjusts the range of the angle of the field of view of a laser scanner based on the information about the speed of the vehicle, and generates second detection data on the object. The detection data integration unit outputs obstacle detection data.

Disclosed herein are an apparatus and method for processing the data of heterogeneous sensors in an integrated manner to classify one or more objects on a road and detect the locations of the objects. The apparatus includes a camera image processing unit, a scanning information processing unit, and an integrated processing unit. The camera image processing unit generates the results of the processing of camera images based on the camera images collected from one or more cameras. The scanning information processing unit generates the results of the processing of scanning information based on the scanning information collected from one or more laser scanners. The integrated processing unit generates the types and final locations of the objects located on the road by processing the generated results of the processing of the camera images and the generated results of the processing of the scanning information in an integrated manner.

Disclosed herein is a method of providing vehicle wireless communication. In the method, a vehicle receives hand-over-related link information, which includes slot request information about slots requested by a vehicle to a roadside wireless communication device for hand-over of the vehicle, from a central control server. A hand-over preparation message, which includes the hand-over-related link information, is send to a vehicle wireless communication device connected to the vehicle. It is determined that the vehicle completed preparation for performance of the hand-over when a response message to the hand-over preparation message is received from the vehicle wireless communication device. Slots are allocated in consideration of the hand-over-related link information. Beacon frames, which include slot allocation information about the allocated slots, are transmitted to the vehicle wireless communication device. Accordingly, the vehicle wireless communication device and the roadside wireless communication device can reliably perform communication without interruption.

Method of providing wireless communication between vehicle and roadside and vehicle wireless communication device using the same

Disclosed herein are a multicasting system and method for a vehicular communication network. The multicasting system includes a plurality of roadside communication devices for communicating with a plurality of vehicular communication devices. Each of the roadside communication devices includes a communication unit for communicating with the plurality of vehicular communication devices and at least one neighboring roadside communication device, a beacon analysis unit for analyzing beacon frames when a slot allocation request is received from one of the vehicular communication devices, a determination unit for searching for a period in which a slot has not been allocated and determining whether a period for allocation of a slot to the vehicular communication device is present, and a slot allocation unit for allocating a slot period for multicasting of the vehicular communication device based on results of the determination of the determination unit.

Multicasting system and method for vehicular communication network

An apparatus and method for detecting the location of a vehicle using results sensed by sensing devices installed outside the vehicle and the internal information of the vehicle without obtaining the current location information of the vehicle using signals transmitted from a Global Positioning System (GPS) satellite, the apparatus for detecting the location of a vehicle includes a location information reception unit for receiving location information that is generated by sensing a vehicle passing by a sensing point and that corresponds to the sensing point. A location detection unit estimates a current location of the vehicle based on information sensed by internal sensors of the vehicle and control information for a vehicle manipulation part while the location information is not received, and corrects the estimated current location of the vehicle using received location information when the location information is received.

Apparatus and method for detecting location of vehicle

Disclosed herein is an apparatus for detecting locations of a vehicle and an obstacle. The apparatus for detecting locations of a vehicle and an obstacle includes at least one distance measurement unit and a data processing unit. The distance measurement unit measures distance data relevant to a vehicle and an obstacle within a measurement area. The data processing unit maps the distance data on a grid layer, detects the location of the vehicle based on the result of the mapping, detects the location of the obstacle based on the detected location of the vehicle, and modifies the detected location of the vehicle using the distance data.
