1. A vibration applying structure detecting device for a wheeled vehicle traveling on a roadway having a vibration applying structure on a road surface in or adjacent to the roadway, comprising:

  • a lane departure judgment device that determines whether there is a lane departure tendency based on camera image taken by a vehicle mounted camera;

    a vibration detecting device that determines the frequency and the amplitude of input vibration from a road surface to the vehicle;

    a contact judgment device that determines that at least one of the wheels of the vehicle is contacting the vibration applying structure when the input vibration with an amplitude equal to or greater than a prescribed vibration amplitude threshold value has a frequency that is equal to or greater than a prescribed vibration frequency threshold value;

    a threshold value setting device that sets one or both of the vibration amplitude threshold value and the vibration frequency threshold value;

    wherein when it is judged by the lane departure tendency judgment device that there is a lane departure tendency, the threshold value setting device sets one or both of the vibration frequency threshold value and the vibration amplitude threshold value to a value smaller than that when it is judged that there is no lane departure tendency; and

    wherein the threshold value setting device returns the vibration frequency threshold value and/or vibration amplitude threshold value of the wheels in a departure direction judged to have a lane departure tendency to the vibration frequency threshold value and/or vibration amplitude threshold value before it was reduced after a first prescribed period of time has passed since the vibration frequency threshold value and/or vibration amplitude threshold value was reduced.
