Pressure assisted positioning method and device thereof are disclosed in the present invention. The pressure assisted positioning device is exerted for positioning a target under the circumstance of altitude change since the target enters a specific region. The pressure assisted positioning method includes the following steps. First, confirming the entrance of the specific region of the target and detecting a plurality of pressure data. Then, calculating a pressure variation between the two selected pressure data. At last, comparing the pressure variation to a threshold. An altitude change within the specific region is confirmed as the pressure variation is greater than the threshold. On the other hand, as the pressure variation is greater than the threshold, it refers to no altitude change within the specific region. Wherein, confirming the entrance of the specific region of the target determines via the result of detecting the target enters a region having at least a distance with a reference location of a structure with altitude change illustrated according to a map information. The pressure assisted positioning device of the present invention can not only directly detect the actual pressure data but calibrate the pressure variation information according to the pressure data and the moving statuses of the target as well. Comparing to the conventional device, the method and device of the present invention can calculate and calibrate the pressure variation information independently without any external pressure data from the barometric station.

A vehicle position calibration method and apparatus thereof are disclosed. The vehicle position calibration method is applicable to a vehicle having a mobile calibration positioning device and at least a vehicle having a positioning device to be calibrated. The method starts with the mobile calibration positioning device transmitting a message of positioning precision level to the positioning device to be calibrated. Then, the positioning device to be calibrated sends a calibration request to the mobile calibration positioning device according to the message of positioning precision level; then the mobile calibration positioning device detects a relative position between the mobile calibration positioning device and the positioning device to be calibrated according to the calibration request. The mobile calibration positioning device computes and transmits a calibrated position to the positioning device to be calibrated; and the positioning device to be calibrated updates the position of the positioning device to be calibrated.

The present disclosure provides an identifying device, an identifying system and a method for identification between a transmitting wireless apparatus and a receiving wireless apparatus, wherein the transmitting wireless apparatus senses a plurality of wireless apparatuses to provide sense information, calculate relative location information between the transmitting wireless apparatus and the wireless apparatuses based on the sense information and convert the relative location information into an identification datum. The transmitting wireless apparatus transmits a broadcast message having the identification datum. When the receiving wireless apparatus receives the broadcast message from the transmitting wireless apparatus, the identification information of the broadcast message is compared with sense information sensed by the receiving wireless apparatus. When the error value between the identification information and the sense information sensed by the receiving wireless apparatus is less than a permissible value, the receiving wireless apparatus is determined as an object receiving the broadcast message.

An assistance system and a generation method of dynamic driving information, which acquire object information of an ambient object near by a main vehicle to establish an ambient object relation list of the main vehicle, receive an ambient object relation list of an ambient vehicle, and determine object information of the ambient object relation list of the ambient vehicle before being added in the ambient object relation list of the main vehicle, so as to establish a dynamic driving information graph.

Assistance system and generation method of dynamic driving information

A moving carrier signal transmission method and a signal transmission device using the same are provided. A main moving carrier acquires an identification code of an ambient moving carrier. The main moving carrier adds an identification code of the main moving carrier and the identification code of the ambient moving carrier in a data request and then sends out the data request to the ambient moving carrier according to the identification code of the ambient moving carrier. When the ambient moving carrier obtains the data request, the ambient moving carrier adds the identification code of the main moving carrier in a moving carrier list and transmits the moving carrier list to the main moving carrier.

A cooperative event data record system includes an in-car system working cooperatively with a communication system. The in-car system has a communication module, a cooperative event record processing unit and an impact determination module. The cooperative event record processing unit connects to the communication module, the impact determination module and an event data record unit. The impact determination module transmits a signal to the cooperative event record processing unit. The communication module transmits a request from the cooperative event record processing unit to a communication module element of the communication system, and receives a response from the communication module element. According to the response, the cooperative event record processing unit stores at least a video data to the event data record unit, or retrieves video data from the event data record unit.
