Method of acquisition and management by a remote server (2) of data relating to road disruptions, in which a device (1) on board a vehicle is able to transmit an information frame to the server (2), the server (2) is able to process said frame and to return information to the onboard device (1) that the latter is able to transmit to the driver of the vehicle, the onboard device (1) periodically receives an information frame from a geolocation system (5), the onboard device (1) determines the acceleration of the vehicle and sends a braking frame to the remote server (2) when: a) the acceleration is negative and greater than a first determined threshold value (5a) b) the variation of the speed of the vehicle is greater than a second threshold value (deltanu), on receipt of the braking frame, the remote server (2) saves said frame in a database. |
