Driver Recorder and Method for Setting Up the Driver Recorder
First Claim
1. A drive recorder comprising:
- an acceleration sensor for detecting a first acceleration along a traveling direction of a vehicle and a second acceleration along a transverse direction of said vehicle; and
a control unit which obtains a combined acceleration based on said first acceleration and on a value obtained by subtracting a correction value from the absolute value of said second acceleration, and when said combined acceleration exceeds a threshold value, records video information received from an image capturing unit onto a recording device.

Abstract
An object of the invention is to provide a drive recorder that can detect acceleration so that the acceleration exerted on a vehicle traveling around a curve will not be erroneously detected as excessive acceleration, as long as the steering wheel is operated in a usual manner. More particularly, the invention provides a drive recorder that includes an acceleration sensor for detecting a first acceleration along a traveling direction of a vehicle and a second acceleration along a transverse direction of the vehicle, and a control unit which obtains a combined acceleration based on the first acceleration and on a value obtained by subtracting a correction value from the absolute value of the second acceleration, and when the combined acceleration exceeds a threshold value, records video information received from an image capturing unit onto a recording device.

5. A method for setting up a driver recorder having an acceleration sensor for detecting a first acceleration along a first direction of a vehicle and a second acceleration along a second direction of said vehicle, said method comprising the steps of:
-
determining that said vehicle has stopped; detecting said first acceleration and said second acceleration when said vehicle has begun to move after stopping; and identifying the acceleration acting in a transverse direction of said vehicle and the acceleration acting in a longitudinal direction of said vehicle on the basis of said first acceleration and said second acceleration. - View Dependent Claims (6, 7, 8, 9, 10)
