Abstract: A method of verifying data integrity performed by on-board equipment in a vehicle, the method comprising: sending data for signing to an electronic chronotachograph on board said vehicle; receiving a signature of said data from said electronic chronotachograph; storing said data and said signature; and transmitting the stored data and signature to a verification device.

Abstract: One embodiment disclosed herein relates to a routing method performed by a unit forming a node in a network made up of a plurality of nodes, the method comprising receiving or generating a message including destination geographical position data representing the geographical position of a destination node of the message and transmitting the message to a neighboring node selected from a plurality of neighboring nodes as a function of the destination geographical position and as a function of a location table, the location table including the geographical position of at least one neighboring node. In some embodiments, the method comprises receiving path data from a neighboring node on board a first vehicle, the path data representing a planned path for the first vehicle and updating the location table as a function of the path data.

Abstract: A device for uphill start-up assistance for a motor vehicle including a control for controlling release of the vehicle mechanical brakes that act on the vehicle wheels, so that the vehicle is maintained on the slope when maneuvering uphill without any intervention from the driver on this maintaining condition. The control uses mainly the state of the slope, the interpretation and anticipation of the commands of driver and/or of a central driving member, and the determined instantaneous clutching characteristics. In a preferred embodiment, the assistance device co-operates with an electrical device of the parking brake.
