Vehicle control device and vehicle state monitoring method

Abstract

A vehicle control device has a plurality of speakers and a security ECU which identifies whether a door is opened or unlocked on the basis of output signals from the speakers. The security ECU identifies the driving direction of a driven portion on the basis of the difference between input times of sounds inputted to the speakers. Moreover, the ECU has RAM containing the waveforms of the signals outputted from the speakers and compares the waveforms of the signals contained in the RAM with the waveforms of the signals outputted from the speakers to identify the driving direction of the driven portion.

Dependencies are inferred from the claim text.
