<p>A travel sensor unit (170) obtains travel conditions of a vehicle, and based on the result of the detection, an impact detection section (210) detects the magnitude and direction of an impact applied to the vehicle. Then, various conditions, such as parking, collision, and unintended movement, of the vehicle are detected based on the result of the detection of the traveling conditions obtained by a travel sensor unit (170) and on the magnitude and direction of the impact applied to the vehicle detected by the impact detection section (210). Conditions of the vehicle can be easily and accurately detected.</p> |
