A method for sensing a traffic environment for use in an electronic device is provided. The method includes: generating local object information by sensing an environment within a first sensing range of the electronic device, wherein the local object information at least includes first geographical distribution information of local objects within the first sensing range; receiving external object information transmitted by at least one node, wherein the external object information includes at least second geographical distribution information of external objects within a second sensing range of the node; and generating object integration information according to the local object information and the external object information.

Method and device for sensing traffic environment

A vehicle, a vehicle positioning system and a vehicle positioning method are provided. The vehicle positioning system includes a 2D image sensor, a 3D sensor and a processor. The 2D image sensor is configured for obtaining 2D image data. The 3D sensor is configured for obtaining 3D point cloud data. The processor is coupled to the 2D image sensor and the 3D sensor, and configured for merging the 2D image data and the 3D point cloud data to generate 3D image data, identifying at least one static object from the 2D image data, obtaining 3D point cloud data of the static object from the 3D image data based on each one of the at least one static object, and calculating a vehicle relative coordinate of the vehicle based on the 3D point cloud data of the static object.

Vehicle, vehicle positioning system, and vehicle positioning method

A roadside detection system, a roadside unit and a roadside communication method are provided. The roadside unit receives a positioning signal from a satellite positioning system and obtains roadside latitude and longitude coordinates and an initialization parameter coordinate. The roadside unit receives object information of the object. The roadside unit obtains object latitude and longitude coordinates, an object speed, an object acceleration, an object length, and an object heading/direction based on the roadside latitude and longitude coordinates, the initialization parameter coordinate, and the object information. The roadside unit converts the object latitude and longitude coordinates, the object speed, the object acceleration, the object length, and the object heading/direction into a V2V Basic Safety Message format.

Roadside detection system, roadside unit and roadside communication method thereof

A communication device, a communication and associated communication method are provided. The communication device is placed at a first moving device and the communication device includes a movement detection module, a transmitter, and a controller. The movement detecting module detects movement of the first moving device to obtain at least one first movement parameter at a first time point, and detects the movement of the first moving device to obtain at least one second movement parameter at a second time point latter than the first time point. The transmitter transmits the at least one first movement parameter. By estimating position of the first moving device at the second time point, the controller obtains an estimated internal movement parameter. The controller controls the transmitter to transmit the at least one second movement parameter selectively according to the estimated internal movement parameter and the at least one second movement parameter.

Communication device, communication system and associated communication method

A vehicle turning alarm method and a vehicle turning alarm device are provided herein. The vehicle turning alarm method includes acquiring map information and vehicle information. The vehicle turning alarm method further includes determining a vehicle status according to the map information and the vehicle information when a vehicle approaches an intersection. The vehicle turning alarm method further includes not sending an alert message if the vehicle status is not a left-turning event.

Vehicle turning alarm method and vehicle turning alarm device

A method of dynamic adjusting a generation frequency of messages in vehicular networks is provided, including: receiving updating requests and emergent degree of the vehicle event, and then determining whether the generation frequency of messages meets the dynamic change of the vehicle, if not satisfied, selecting a different adjustment method according to the event emergent degree. When the event is emergent, its generation frequency can be raised immediately by an interruptive adjustment and to suppress the generation frequency of messages of the others. Conversely, adjusting its generation frequency by a progressive adjustment and reducing the generation frequency of messages of the other lower-priority vehicles. According to the present disclosure, it prevents lower priority messages from occupying the channel overly, and emergency messages with higher priority can be satisfied immediately when it needed.
