Abstract:
A vehicular electronic control device (13) comprises: a microcontroller (24) including a nonvolatile memory (31) which can store software including programs and data, the nonvolatile memory including a first area and a second area as memory areas, and a control unit (32) which includes a first core and a second core and which executes, on at least one of the first and second cores, a rewriting program for rewriting software; and an external storage unit (27) which is provided externally to the microcontroller and which temporarily stores reprogramming data for updating software. If the control unit determines a rewrite of its own software on the basis of specifications data, the control unit uses a memory area in the external storage unit to rewrite the software stored in the nonvolatile memory.
