Patent ID: 11167550

Abstract:
A state determination apparatus that does not need an increase in number of inputs of a calculation element for duplicated sensors even in a case where a sensor is duplicated, and can detect a malfunction of a plurality of duplicated sensors is provided. The object is resolved by a state determination apparatus including a plurality of sensors that detect a state of the same determination target in a duplicated manner, a selector element that receives an input of the detection signal of each sensor of the plurality of sensors and sequentially outputs the detection signal of one sensor among the detection signals of the sensors in synchronization with a first clock signal having a first frequency, and a storage unit that receives an input of an output signal of the selector element and sequentially stores a logical level of the output signal of the selector element in a bit width greater than or equal to the number of the plurality of sensors in synchronization with a second clock signal having a second frequency higher than or equal to the first frequency.
