1. A method for updating operating software for subcomponents of a motor vehicle, comprising:
a) detecting a trigger signal for updating the operating software of at least a subset of subcomponents installed in the motor vehicle, the operation of which requires an operating software;
b) determining vehicle functions present in the motor vehicle, the execution of which involves multiple subcomponents, which represent different components each with their own operating software;
c) identifying at least the subcomponents involved in the execution of a respective determined vehicle function;
d) creating an individual function matrix for at least one specific vehicle function comprising at least the subcomponents identified for this vehicle function in step c) and the actual status of the operating software respectively installed on the multiple subcomponents;
e) transmitting at least this individual function matrix to a backend server;
f) in the backend server: comparing the actual status of the operating software installed on the subcomponents of the transmitted individual function matrix with a corresponding target status to determine differences between the actual and target status;
g) if a difference is found between the actual and the target status: updating the operating software at least of the subcomponents of the individual function matrix for which a difference between the actual and the target status was found; and
h) initializing the at least one vehicle function, for which the operating software was updated for at least one of multiple subcomponents of the associated individual function matrix.
