  • Device for checking the tire profile depth and profile type, and the speed and ground clearance of vehicles in motion
    Patent number: 7797995
    Abstract: A device for detecting a profile depth and/or a profile type of a vehicle tire has a profile-measuring device, a camera system for detecting the vehicle, an evaluating unit, which couples the profile-measuring device and the camera system to one another; and further having at least one of the components: a speed-measuring device for detecting the vehicle speed; a direction of travel-measuring device for detecting the steering situation or movement direction of the vehicle, wherein the evaluating unit is designed to produce a measuring signal for the current acceleration of the vehicle and the control is designed to permit an evaluation only when the vehicle is situated in a preset frame at a relatively uniform speed; and wherein a measuring signal for the movement direction of the vehicle can be produced by the evaluating unit and the measuring signal is provided for control of the evaluation of the profile measurement and the control is designed to permit an evaluation only when the vehicle is situated in a
