Abstract: An object tracking method and an object tracking system are provided. The method includes: obtaining a first relative position vector from a first node to a second node at a first time point; obtaining a first position data of the first node and a second position data of the second node at a second time point; identifying a position variation vector from the first node to the second node based on the first position data of the first node and the second position data of the second node; and identifying a second relative position vector from the first node to the second node at the second time point based on the first relative position vector and the position variation vector. The method improves the tracking accuracy.

Abstract: The present disclosure relates to object detection and object distance determination by an assisted driving system of a vehicle. In one embodiment, a method includes receiving image data detected and detecting at least one object in the image data. Detecting includes determining a region of interest in the image, classifying the object and localizing the region of interest in the image data. The method may include determining a distance value for the at least one object, wherein the distance determination is determined based on the category determined, localization of the region of interest, and object size relative to the image data. The method may include outputting a distance value determination for the at least one object.

Abstract: A lane detection method and a lane detection system mounted on a first vehicle are provided. The methods includes: calculating on which lane a first vehicle is located based on vehicle-to-vehicle data received by the first vehicle from at least one neighboring vehicle, where the neighboring vehicle means another vehicle located within a vehicle-to-vehicle communication range of the first vehicle. The system may include: a communication device for receiving vehicle-to-vehicle data from at least one neighboring vehicle, and a processing device for calculating on which lane the first vehicle is located based on the vehicle-to-vehicle data received by the communication device, where the neighboring vehicle means another vehicle located within a vehicle-to-vehicle communication range of the first vehicle. Lane detection may not rely on marks on roads which are inherently not clear or blur due to a bad weather.

Abstract: A method for communicating messages in a channel of a wireless communication network is provided. In the channel, successive cycles, each of which including a predetermined number of successive time slots, are defined. The method may include: a first node obtaining a first list of its neighboring nodes before a first qth time slot; broadcasting a first message in the first qth time slot; receiving acknowledge information from other nodes within the network for one cycle after the first qth time slot; obtaining a second list of its neighboring nodes after the first qth time slot; and determining whether qth time slots are proper for communicating messages by the first node by checking whether all nodes on both the first and the second lists have received the first message based on the received acknowledge information, each piece of which indicates whether a corresponding node has received the first message.

Abstract: A trajectory detection method and a trajectory detection system are provided. The method includes: receiving, on a first vehicle, from a second vehicle, dynamic data containing at least one dynamic feature of the second vehicle; detecting a relative position of the second vehicle with regard to the first vehicle using an object detection sensor mounted on the first vehicle; and generating a trajectory of the second vehicle based on the relative position and the dynamic data. Accuracy may be improved.

Abstract: A method of resource allocation for Channel State Information (CSI) feedback is provided, which comprises the following steps of: configuring a downlink transmission approach and a feedback mode for each User Equipment (UE); allocating feedback resources required for CSI feedback by each UE based on the configured downlink transmission approach and feedback mode, such that different types underlying different feedback modes for a single UE will not collide with each other within one sub-frame; and notifying each UE of the corresponding configured downlink transmission approach and feedback mode and allocated feedback resources.
