Device for checking the tire profile depth and profile type, and the speed and ground clearance of vehicles in motion
First Claim
1. Device for detecting a profile depth and/or a profile type of a profile of a vehicle tire during travel on one vehicle moving relative to the device out of a plurality of vehicles, in particular in flowing traffic, said device comprising:
- a profile measurement means;
a camera system for recording the vehicle;
an evaluation unit which couples the profile measurement means and the camera system to one another;
a speed measurement means for detecting vehicle speed;
a direction of travel measurement means for detecting a steering state or direction of motion of the vehicle,the evaluation unit being configured to produce a measurement signal for measuring a current acceleration of the vehicle, and a control system configured to allow an evaluation of the one of the plurality of vehicles only if the vehicle is situated in a predetermined frame at a relatively uniform speed; and
a measurement signal for detecting the direction of motion of the vehicle being produced by the evaluation unit, the measurement signal being provided for controlling the evaluation of the profile measurement, and the control system further being configured to allow the evaluation of the one of the plurality of vehicles only if the vehicle is situated in a predetermined frame and is traveling in a straight line.

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 preset frame when traveling in a straight line.
