The present patent application relates to a system (1) for automatic crash notification for an automotive vehicle (2). The system (1) comprises wireless communications means (5) and means (6) for receiving data from a positioning system to derive positional information. Further the system comprises means (7) for triggering communication of crash notification messages comprising said positional information using said wireless communications means (5), where said triggering means are arranged to detect and characterize crash information provided to an existing vehicle bus (3), such as a Controller Area Network (CAN) serial bus, by at least one crash sensor within said vehicle. The means (7) for triggering communication of crash notification messages further comprise means (8) for determining the operational status of said vehicle bus, and integrated means (9) for determining inferring a crash like situation and triggering communication of a crash notification message upon such determination if said vehicle bus (3) is determined to have suffered an unexpected malfunction or failure. <IMAGE> |
