Device for determining e.g. wear of ceramic brake disk of motor vehicle, has indicators whose image is received by camera, and image processing unit determining abrasion and/or wear of disk based on brightness distribution in image

摘要

The device has a set of wear indicators (10) introduced in a friction surface (8) of brake rings (2). An image of the wear indicators is received by a camera, and an image processing unit automatically determines an abrasion and/or a wear of a ceramic brake disk based on brightness distribution in the affiliated image. A brightness threshold value is set or adjusted based on the set or adjusted threshold value, an unworn region of the upper surface of the wear indicators is separated from a region with break-out in the upper surface of the indicators in the image. An independent claim is also included for a method for determining abrasion and/or wear of a ceramic brake disk of a motor vehicle.
