Data management method and device, storage medium and electronic equipment

The embodiment of the invention provides a data management method and device, a storage medium and electronic equipment, and relates to the field of automotive electronics. Wherein the main control ECU provides an extended storage space for at least one user ECU, and the main control ECU obtains the current working state of the main control ECU; if the working state meets the speed limiting condition, determining a first target user ECU from the at least one user ECU; and the access speed of the first target user ECU to the extended storage space of the first target user ECU is reduced. In this way, on the premise that normal work of the master control ECU is guaranteed, shared storage space is provided for other user ECUs. 本实施例提供的一种数据管理方法、装置、存储介质及电子设备，涉及汽车电子领域。其中，主控ECU为至少一个用户ECU提供有扩展存储空间，主控ECU获取主控ECU当前的工作状态；若工作状态满足限速条件，则从至少一个用户ECU中确定出第一目标用户ECU；降低第一目标用户ECU对自身扩展存储空间的访问速度。如此，保证主控ECU正常工作的前提下，为其他用户ECU提供共享存储空间。
