A method for controlling a communication (C) between a vehicle and a backend device in a vehicle-to-cloud-system , the method comprising: - establishing a first list (L1) of mobile online services (MOD) used by vehicle devices and corresponding data types (D) used by the mobile online services (MOD), - establishing a second list (L2) of the data types (D) used by the mobile online services (MOD) and corresponding privacy levels (P) of the data types (D), - receiving a request (r) from at least one of the mobile online services (MOD) to connect the backend device , - verifying an authorization of the at least one of the mobile online services (MOD) to connect the backend device upon the request (r), depending on: - the privacy levels (P) corresponding to the data types (D) used by the at least one of the mobile online services (MOD) and - current privacy settings (S) of the vehicle , - connecting the at least one of the mobile online services (MOD) and the backend device , if the at least one of the mobile online services (MOD) is authorized to connect the backend device , - wherein the at least one of the mobile online services (MOD) is authorized to connect the backend device , when it uses data types (D) corresponding to at least one privacy level (P) being higher than or equal to the current privacy settings (S) of the vehicle , - and wherein, if the data types (D) used by the at least one of the mobile online services (MOD) requesting for a connection to the backend device comprise dormant operation data (D6), the connection is allowed, even if the current privacy settings (S) of the vehicle are set to a high level of privacy, in order to allow a transmission of vital data between the vehicle and the backend device . - establishing a first list (L1) of mobile online services (MOD) used by vehicle devices and corresponding data types (D) used by the mobile online services (MOD), - establishing a second list (L2) of the data types (D) used by the mobile online services (MOD) and corresponding privacy levels (P) of the data types (D), - receiving a request (r) from at least one of the mobile online services (MOD) to connect the backend device , - verifying an authorization of the at least one of the mobile online services (MOD) to connect the backend device upon the request (r), depending on: - the privacy levels (P) corresponding to the data types (D) used by the at least one of the mobile online services (MOD) and - current privacy settings (S) of the vehicle , - the privacy levels (P) corresponding to the data types (D) used by the at least one of the mobile online services (MOD) and - current privacy settings (S) of the vehicle , - connecting the at least one of the mobile online services (MOD) and the backend device , if the at least one of the mobile online services (MOD) is authorized to connect the backend device , - wherein the at least one of the mobile online services (MOD) is authorized to connect the backend device , when it uses data types (D) corresponding to at least one privacy level (P) being higher than or equal to the current privacy settings (S) of the vehicle , - and wherein, if the data types (D) used by the at least one of the mobile online services (MOD) requesting for a connection to the backend device comprise dormant operation data (D6), the connection is allowed, even if the current privacy settings (S) of the vehicle are set to a high level of privacy, in order to allow a transmission of vital data between the vehicle and the backend device . <EOS>
