Integrated and off Line Testing in the Vehicle final Assembly 973051
The growing proportion of comfort equipment and electronics in modern vehicles results in the fact that increasingly extensive tests and parameter setting tasks occure at the end of line.
With the concept of the end of line tests of today, which means use of highly specialized single test stands, these requirements can no longer be complied with. The trend is towards flexible test stands designed according to the vehicle equipment and the test profile.
This results in a test concept in which the tests are no longer carried out by the control of the respective test stand but by the vehicle's ECU. In the first step, this isa mobile test unit which communicates directly with the vehicle's control device and automatically generates test programs which are worked-off with the help of the respective test stand. Apart from performing the test itself, this unit also sets the parameters of the ECU.
This development leads to a new type of test stand concept and to a redistribution of the test tasks in the end of line area and results in cost and testing time reduction.
