Claim 6:
7. A common storage management device for a system including a common storage and a plurality of electronic control devices connected with an in-vehicle network, each of the plurality of electronic control devices being configured to execute at least one application, the at least one application being configured to write data to and read data from the common storage, the common storage management device comprising:
at least one processor configured to:
receive a first request from the at least one application to reserve and release the first storage space of the common storage for storing first data;
manage a reservation of the first storage space of the common storage in response to the first request;
notify the at least one application of a second request to reduce data size of the first data for which the first storage space of the common storage is required to be reserved in response to the second request, when the at least one application requests to reserve the first storage space for the first data and free storage space of the common storage is insufficient for reserving the first storage space for the first data; and
determine whether the free storage space of the common storage is sufficient to reserve a second storage space for storing the first data to the common storage whose data size is reduced in response to the second request when the at least one application requests to reserve the second storage space of the common storage for the first data after reducing the data size of the first data.
