Upcoming vehicles will be intelligent and autonomous with benefits on efficiency and safety of road networks and new mobility services never imagined before. Sensors can fail in case of adverse weather conditions such as fog or rain. Increasing the number of sensors and their quality leads to increased costs and not necessarily increased system reliability. The proposed method provides a high throughput and high-reliability data exchange exploiting dynamically two communication interfaces, the main one at high frequency (220) and the lower frequency as supporting interface (230).
A wide range of sensors are used for environment perception in self-driving cars. However, they can fail to meet the safety standards required. The proposed method is designed to overcome all the weaknesses reported. Differently from known approaches, it describes a proactive system where a first agent (vehicle, road-side unit, or network entity) requests and directly access one or more sensors of a second agent, where at least one of the two agents is mobile. The first agent asks for the list of available sensors and the related addresses. The second agent received the request of the first agent, creates a virtual port for each available sensor, and associates a virtual address to each virtual port. The virtual ports will duplicate the raw data of the associated physical sensors, thus acting as virtual sensors. The second agent sends the list with available sensors and related virtual addresses to the first agent. Finally, the first agent can establish a virtual databus directly with the virtual sensor through the virtual address.
