In at least two groups of independent sensors connected to an electronic control device(s), at least two output signal ports are included in a sensor of a first group, and one output signal port is included in a sensor of a second group; and two output signals in the first group have different characteristics while having a constant relationship to each other defined in advance, and the one output signal in the second group has an equivalent characteristic to either one of the two output signals in the first group. The electronic control device(s) includes an abnormality determination unit which is configured in such a manner that all of output signals of the output signal ports are compared, and, for the control by the electronic control device(s), only a normal output signal(s) is used among the output signals thereof having been determined by the abnormality determination unit.
