Functional Validation of Steering Actuators - Test Bench Control via VT System

In order to validate system requirements for passenger car rear axle steering systems, ZF uses the Vector VT System to control a HiL test bench.
Christopf Koch, Team Manager Testfield Mechatronics in the R&D department of the Product Line Chassi Actuators at ZF, gives a detailed insight into the test process and the components required for it.
