Abstract
An electronic control system for vehicles includes an electronic control device and a master device. The master device is connected to at least two or more groups of electronic control devices each including the electronic control device and gives an instruction to the electronic control device. The electronic control device includes a storage unit including a data storage side; a second detection unit that detects a state of a vehicle; a rewrite execution unit that writes update data acquired from the master device to the data storage side to rewrite a program; an activation determination unit that determines whether or not to activate the program rewritten with the update data; and an activation execution unit that activates the program. The master device includes an update data acquisition unit that acquires the update data from an external instrument; a first detection unit that detects the state of the vehicle, the first detection unit being different from the second detection unit; a rewrite instruction unit that instructs the rewrite execution unit to write the update data to the data storage side; and an activation instruction unit that instructs the activation execution un…
