Abstract
The invention concerns a device and a method for detecting a tire on a vehicle to determine whether there is a single or twin tire on an axle. The device has an optical sensor for this purpose, the sensor detecting at least one region of a rim on which a tire to be determined is mounted. An evaluation unit is also provided which is designed to determine a shape of the area of the rim from the sensor signals and to generate a signal from the shape which represents the type of tire.
Claims10
A device for detecting a tire of a vehicle (12) for determining whether single or twin tires are present on each end of an axle (36, 38, 40), comprising:
- an optical sensor (20, 24), wherein the optical sensor (20, 24) detects at least one region of a rim (46, 48) on which the tire is mounted, the optical sensor (20, 24) generating a sensor signal based on said detection;
- and
- an evaluation unit (26) configured to determine a shape of the at least one region of the rim (46, 48) from the sensor signal generated by the optical sensor (20, 24) and, as a function of the determined shape, generates an evaluation unit signal which represents whether single or twin tires are mounted on each of the ends of the axle (36, 38, 40).
A method for detecting a tire of a vehicle for determining whether single or twin tires are mounted on each end of an axle, comprising the steps:
- providing an optical sensor;
- detecting with the optical sensor at least one region of a rim on which a tire is mounted, and generating corresponding sensor data;
- determining a shape of the at least one region of the rim from the sensor data;
- determining whether single or twin tires are mounted on each of the ends of the axle from the shape of the at least one region of the rim;
- and
- outputting a signal to indicate whether single or twin tires are mounted on each of the ends of the axle.
