Abstract:
1. An electronic control device comprising: one or more substrates; a casing in which the one or more substrates are disposed; a plurality of circuit blocks disposed on the one or more substrates; a common wire shared by the plurality of circuit blocks; a plurality of branch wires respectively coupled between the plurality of circuit blocks and the common wire; and two interrupt wires respectively coupled with two circuit blocks of the plurality of circuit blocks via two branch wires of the plurality of branch wires for overcurrent protection of the plurality of circuit blocks, wherein the two circuit blocks include one circuit block that performs a function having a lower importance and another circuit block that performs a function having a higher importance than the function having a lower importance performed by the one circuit block, the interrupt wire coupled with the one circuit block has a smaller interrupting current than an interrupting current of the other interrupt wire coupled with the another circuit block, the electronic control device is used in a vehicle control system of a vehicle, and the lower importance of the function performed by the one circuit block and the higher importance of the function performed by the another circuit block are predetermined according to which function is more critical to the vehicle's safety when the vehicle is traveling.
