Driver recorder and method for setting up the driver recorder
First Claim
1. A drive recorder comprising:
- a sensor for detecting a first acceleration along a traveling direction of a vehicle and a second acceleration along a transverse direction of said vehicle;
a determining unit configured to determine whether the vehicle is traveling around a curve when the vehicle is traveling; and
a control unit configured to obtain a combined acceleration based on said first acceleration and a value obtained by subtracting a correction value from an absolute value of said second acceleration when the determining unit determines the vehicle is traveling around a curve, and when said combined acceleration exceeds a threshold value, to record video information received from an image capturing unit, in 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.

4. A drive recorder comprising:
-
a control unit configured to determine whether a recording condition is established, on the basis of a signal from a sensor which detects an acceleration of a vehicle, and a threshold; and a determining unit configured to determine whether the vehicle is traveling around a curve, when the vehicle is traveling, wherein when the determining unit determines the vehicle is traveling around a curve, the control unit adjusts the relationship between the signal and the threshold.

5. A drive recorder comprising:
-
a control unit configured to determine whether a recording condition is established on the basis of a signal from a sensor which at least detects an acceleration of a vehicle along a transverse direction of the vehicle, and a threshold; and a determining unit for determining as to whether the vehicle is traveling around a curve when the vehicle is traveling or not, wherein when the determining unit determines the vehicle is traveling around a curve, the control unit adjusts a detection sensitivity of the sensor more sensitive than a detection sensitivity of the sensor when the vehicle is not traveling around a curve.
