<p>The electronic control apparatus includes at least two microcomputers at least one of which is always supplied with electric power and configured such that, when rewriting of control software of these microcomputers are performed, control software of the microcomputer always supplied with electric power is rewritten after control software of the other microcomputer is rewritten. The electronic control apparatus has a configuration which makes it possible to correctly and reliably rewrite the control software for each of these microcomputers in succession.</p> |
