Benchmark of Different Calibration Methods of Driver Assistance Systems (DAS) Sensors at the End of Line of a Truck Final Assembly Plant by a Tolerance Chain Analysis

For the proper function of modern Driver Assistance Systems, all related sensors need to be calibrated to the coordinate system of the truck. Today, several different systems for such calibration operation are available on the market to perform the calibration in the End of Line area of a truck final assembly plant. This benchmark compares three different systems under the condition that the process for positioning of calibration targets related to the driving direction of trucks is capable (cpk > 1.33). A tolerance chain analysis of the positioning systems has been made to determine the related capability of each system. For the process of measuring the driving direction of a truck, several measurements have been made with each system.
