Abstract: A communication device for a vehicle comprises a plurality of communication means and a rule base. The communication device is designed to determine a communication means to use using said rule base. The communication device is further designed to: check with a remote server as to whether an update of the rule base is available, download the rule base update, and update the rule base using the downloaded rule base.

Abstract: The invention relates to a method, implemented by a terminal, for commanding the establishment of a vehicle accident report, from a telematic computer of the vehicle, characterized in that it comprises the steps of: subscribing, from the telematic computer of the vehicle, to a data publication service, for at least one datum representing a vehicle parameter; repeatedly receiving values for the datum representing a vehicle parameter; determining from the received values, whether the vehicle has been involved in an accident; if the vehicle has been involved in an accident, transmitting to the telematic computer an accident report request; receiving an accident report signed and encrypted by the telematic computer; transmitting the signed and encrypted accident report to a remote server.

Abstract: A hydraulic shock absorber equipped with a leading stop, comprising a piston (4) sliding inside a body (2) for the purpose of shock absorption. The piston (4) moves a sleeve (10) which is disposed towards the front and provided with axially-distributed holes (18), and, at the shock absorber end-of-stroke, the sleeve fits around a stationary chamber (12) that gradually closes the holes (18), thereby reducing the cross-section through which fluid can flow into the sleeve (10). The chamber (12) comprises additional holes (40a, 40b) and said chamber (12) receives a moving gate (42) therein, which, depending on its position, either closes or opens the additional holes (40a, 40b).
