1. An in-vehicle system comprising:
a first in-vehicle device installed in a vehicle;
a second in-vehicle device controlled in accordance with a signal output from the first in-vehicle device;
a first in-vehicle ECU communicably connected to the first in-vehicle device and the second in-vehicle device by signal lines; and
a second in-vehicle ECU communicably connected to the first in-vehicle device and the second in-vehicle device by the signal lines,
wherein the first in-vehicle ECU and the second in-vehicle ECU are connected by a communication line of a type different from a type of the signal lines, and
a communication path including a first path and a second path independent of the first path, wherein the first in-vehicle ECU relays the first path from the first in-vehicle device to the second in-vehicle device, and the second in-vehicle ECU relays the second path from the first in-vehicle device to the second in-vehicle device so as to provide a redundant path for the signal output from the first in-vehicle device to the second in-vehicle device.
