Abstract: The invention pertains to a method for estimating the attention level of the driver of a vehicle in a traffic lane, comprising the following steps: —the continuous capture of images (10) of the ground, —the reconstruction of an aerial view (11, 12) of a ground segment at successive instants t, —the reconstruction of an aerial view (11, 12) of a road segment at successive current instants t, —the estimation of the lateral position of the vehicle (100) in the reconstructed aerial view (11, 12), and the storage of said estimated positions of the vehicle, —the determination of an estimated attention level of the driver at a past instant t3, as a function: o of the evolution of the lateral position of the vehicle, o of the analysis of the profile of a road portion at least partially situated upstream of the vehicle at the instant t3.

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).
