<p>PROBLEM TO BE SOLVED: To propose a vehicle stop determination apparatus for determining a vehicle stop reliably even in the case of incorporating an appliance that cannot obtain vehicular information such as a signal of a vehicle speed sensor in a vehicle that has large variation of vibration even when the vehicle is stopped and makes it possible to secure a space for installing an acceleration sensor.SOLUTION: A vehicle stop determination apparatus 1 includes: a three-axis acceleration sensor 12, disposed in a vehicle 2, for measuring acceleration in three different directions; a high-frequency pass filter 22 for attenuating a lower frequency component lower than a predetermined cut-off frequency for a measurement value of the three-axis acceleration sensor 12; and a determination process part 23 for determining whether the vehicle 2 is stopped, on the basis of a comparison between a frequency component of the measurement value that has passed through the high-frequency pass filter 22 and a determination threshold Vth.</p> |
