Abstract
A rough road determination device () is mounted on a vehicle () that is equipped with an internal combustion engine () having a crank angle sensor (). This rough road determination device is equipped with determination means () for determining whether or not a road on which the vehicle travels is a rough road, by comparing a first amplitude fluctuation amount as an amplitude fluctuation amount of one pulse of an output of the crank angle sensor, which is determined in advance on the basis of a rotational speed of the internal combustion engine, with a second amplitude fluctuation amount as an amplitude fluctuation amount of one pulse that is actually output from the crank angle sensor.
