Innovative steering systems require extensive testing procedures before they are ready for on-road use. Safety, durability and comfort aspects have to be proven before mass production even starts. This processes can take high amounts of test drives on specially equipped prototype vehicles, which is expensive, difficult to reproduce and sometimes even dangerous. To enhance all aspects of the testing process, a hardware-in-the-loop (HiL) test bench for hydraulic steering systems is developed at the University of Rostock, which will be used to emulate several vehicle parameters, driving maneuvers and system failures of the steering system.
As an answer to component modularity of steering systems, this HiL test bench is designed to keep up with fast test environment modification without any effort. Therefore, the interfaces between the steering system and the vehicle reactions are determined in the hydraulic system, instead of the steering mechanics. This makes it possible to reduce the amount of mechanical steering components, such as the respective steering axle, on the test bench and emulate their characteristics in the vehicle model, to start testing even in the development state.
