The digital content is transmitted to at least one terminal in the form a data stream. The access criterion is stored in the terminal as a function of an identifier. The terminal receives the data stream in association with a control message indicating the identifier.

Finally, it verifies whether the stored access criterion is satisfied in order, where appropriate, to authorize access to the content.

Abstract: A method for simulating the behavior of a tire mounted on a vehicle in running conditions on the ground, wherein a mechanical model is provided for essentially computing the longitudinal (Fx) and transverse (Fy) stresses transmitted by the tire between the ground and the vehicle in accordance with dynamic parameters related to the physical conditions of the tire running and use and in accordance with physical tire-specific parameters. The mechanical model is set and solved in an iterative manner, under the assumption that the tire in contact with the surface of the ground has an adherence contact area and a sliding contact area and under the assumption that there is a unique x-coordinate point b that is indicative of the transition between the two contact areas.

According to the invention, the access rights entered in an access control module comprise the following variables: right identification variable (R ID), action date variable (AD V) and right status variable (S V).
