Abstract
The invention relates to an automotive control device and a period measurement method for measuring a period of a pulse signal input from outside. The automotive control device processes the pulse signal input from outside using an analog filter in parallel with a digital filter. When a difference between a measured value of a period of an output signal of analog filter and a measured value of a period of an output signal of digital filter is less than a threshold value, the automotive control device selects the measured value of the period of the output signal of analog filter as the period of the pulse signal. Meanwhile, when the difference between the measured values is greater than the threshold value, the automotive control device selects the measured value of the period of the output signal of digital filter as the period of the pulse signal.
