Patent ID: 7266433

Claim:
A data recording apparatus for a vehicle, comprising: a vehicle state detecting sensor configured to detect a state of the vehicle at the time of traveling and to provide an output value; a recorder configured to record the output value of the vehicle state detecting sensor; and a controller configured to record the output value of the vehicle state detecting sensor into the recorder, the controller including: a counter configured to perform counting repeatedly according to a counting frequency and a counting range which are set based on a frequency band of an output signal of the vehicle state detecting sensor; a count value recorder configured to record a count value of the counter; and a judging section configured to judge a state of the output value of the vehicle state detecting sensor, wherein the controller is configured to record the output value of the vehicle state detecting sensor into the recorder every time when the count value of the counter meets a predetermined value, and wherein the controller is configured to record the count value of the counter, at a time point in which the output value of the vehicle state detecting sensor has satisfied a predetermined condition, into the count value recorder, when the judging section has judged that the output value of the vehicle state detecting sensor satisfies the predetermined condition.
