Document Type and Number:
WIPO Patent Application WO/2019/123747
Kind Code:
A1
Abstract:
An objective of the present invention is to provide an electronic control device for automobile capable of reducing an update time of software stored in a nonvolatile memory. This electronic control device for automobile comprises a nonvolatile memory in which data can be deleted in deletion block units and data can be written in writing block units which are the same as or smaller than the deletion blocks, a control program being stored in each of storage regions configured in units of integer multiples of the deletion blocks in the nonvolatile memory, and the device is characterized in that when, in response to an external overwrite request, a portion of the data in the nonvolatile memory is deleted in the deletion block units and the data is written to the nonvolatile memory in the write block units, an overwrite error check is carried out for each of the blocks.
