![]() ![]() Said exchanging of information comprises transmitting, receiving, processing and/or discarding a collective perception message (CPM) containing information about on-board sensors and/or objects detected by said on-board sensors within a traffic environment. The present disclosure provides a method, a cooperative intelligent transport system and a computer-implemented system capable of ensuring that, specifically for CPM and in a congested V2X wireless channel, packets including significant information safely transmitted and prevented from being dropped.Īccording to an aspect of the present disclosure, a method of exchanging information in a cooperative intelligent transport system between stations in said cooperative intelligent transport system (C-ITS) uses a wireless communication channel. The aims of V2V include notifying drivers of critical and dangerous situations at an early stage, improving the vehicles’ awareness of their surroundings, supporting the vehicles’ driver assistance systems, and supporting cooperative automated mobility, thereby improving traffic safety and optimizing traffic flow. In V2X, for example, safety and traffic messages, emergency and service data, toll billing and navigation as well as Internet and database content are exchanged. Alternatively, the wireless communication can be based on the 3GPP standards, specifically termed Cellular-V2X, C-V2X, or sidelink. Wireless communication can be based on the IEEE 802.11 WLAN standard (the 802.11p extension, and e.g., its European profile ITS-G5) and is specifically termed WLAN-V2X. V2X is a generic term for traffic networking, electronic communication of road users with each other in the forms of vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-network (V2N) and vehicle-to-pedestrian (V2P). The method includes: detecting multiple objects present within a field of view (FOV) of at least one sensor provided at a respective station or included in a shared message received from another station as being present in the vicinity of the station obtaining object data of each detected object from said at least one sensor and/or said shared message filling a collective perception message (CPM) with object data of the objects calculating a collective perception message significance index (CPM-SI) for each collective perception message (CPM) filled with object data determining available channel resources of said wireless communication channel and transmitting collective perception messages (CPMs) in accordance with the available channel resources starting with a CPM with the highest collective perception message significance index (CPM-SI). ![]() Google has not performed a legal analysis and makes no representation as to the accuracy of the date listed.)
