Multimedia motor-vehicle communication system configured to generate interaction requests, to assign to each of the interaction requests an indicator (a, b,..., z) representative of a type of interaction, and to transmit these interaction requests to an occupant of the vehicle via a communication module, characterized in that it comprises a request management module for managing interaction requests, which comprises: - a contextual analysis module configured, on the one hand, to define, on the basis of a plurality of contextual data of a driving situation of the vehicle at a given time (t), a plurality of contextual state vectors (1, 2,..., n) of the driving situation, each contextual state vector (1, 2,..., n) containing a plurality of contextual parameters (p1,..., p, p1',..., p',..., pi,..., pj) of the driving situation, - a concatenation unit configured to combine the contextual state vectors (1, 2,..., n) of the driving situation into an overall state vector of the driving situation, - a general data cluster in which a plurality of predefined overall state vectors (B1, B2,..., Bx) are stored, each of which is assigned, for each type of interaction (a, b,..., z), a label (C1, C2,..., Cx) representative of a permission or prohibition to present the interaction request to the occupant of the vehicle, - a decision module configured to compare the overall state vector of the driving situation with the predefined overall state vectors (B1, B2,..., Bx) of the general data cluster in order to derive therefrom a label of the overall state vector of the driving situation representative of a permission or prohibition to present the interaction request to the occupant of the vehicle, the request management module being configured to command the communication module to present the interaction request to the occupant of the vehicle depending on the label of the overall state vector of the driving situation. - a contextual analysis module configured, on the one hand, to define, on the basis of a plurality of contextual data of a driving situation of the vehicle at a given time (t), a plurality of contextual state vectors (1, 2,..., n) of the driving situation, each contextual state vector (1, 2,..., n) containing a plurality of contextual parameters (p1,..., p, p1',..., p',..., pi,..., pj) of the driving situation, - a concatenation unit configured to combine the contextual state vectors (1, 2,..., n) of the driving situation into an overall state vector of the driving situation, - a general data cluster in which a plurality of predefined overall state vectors (B1, B2,..., Bx) are stored, each of which is assigned, for each type of interaction (a, b,..., z), a label (C1, C2,..., Cx) representative of a permission or prohibition to present the interaction request to the occupant of the vehicle, - a decision module configured to compare the overall state vector of the driving situation with the predefined overall state vectors (B1, B2,..., Bx) of the general data cluster in order to derive therefrom a label of the overall state vector of the driving situation representative of a permission or prohibition to present the interaction request to the occupant of the vehicle, the request management module being configured to command the communication module to present the interaction request to the occupant of the vehicle depending on the label of the overall state vector of the driving situation.
