Data recording apparatus for vehicle
First Claim
1. 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, andwherein 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.

8. A data recording apparatus for a vehicle, comprising:
-
an acceleration sensor configured to detect impulsive force applied externally to the vehicle; a traveling state detecting sensor configured to detect a traveling state of the vehicle; a recorder configured to record an output value of each of the acceleration sensor and the traveling state detecting sensor; a controller configured to record the output value of each of the acceleration sensor and the traveling state detecting sensor into the recorder, the controller including; a first counter configured to perform counting repeatedly according to a first counting frequency and a first counting range which are based on a frequency band of an output signal of the acceleration sensor; a second counter configured to perform counting repeatedly, in synchronization with count timing of the first counter, according to a second counting frequency and a second counting range which are based on a frequency band of an output signal of the traveling state detecting sensor; a count value recorder configured to record a count value of each of the first counter and the second counter; and a judging section configured to judge a state of the output value of the acceleration sensor, wherein the controller is configured to record the output value of the acceleration sensor into the recorder every time when the count value of the first counter meets a first predetermined value, and to record the output value of the traveling state detecting sensor into the recorder every time when the count value of the second counter meets a second predetermined value, and wherein the controller is configured to record the count value of each of the first counter and the second counter, at a time point in which the output value of the acceleration sensor has satisfied a predetermined condition, into the count value recorder, when the judging section has judged that the output value of the acceleration sensor satisfies the predetermined condition. - View Dependent Claims (9, 10, 11, 12, 14, 15, 16)
