Which tests can be performed?
This test bench enables tests for steering systems based on EPS (electric power steering) that support the steering command electromechanically as well as for Steer-by-Wire systems that forward the steering command electrically without a mechanical steering column. Independently from the steering system type, a variety of test have to be performed during the development process. Function tests focus on the inherent effect of the steering system functions.
What other options are available?
The test bench from IPG Automotive also offers options such as the Driver-in-the-Loop platform (DIL) as well as the Hands Off Clutch. With DIL, a real driver can manually give steering commands, evaluate the steering feel and sense haptic feedback from ADAS. Our Hands Off Clutch device developed in-house simulates letting go of the steering wheel during the test runs. This allows to test ADAS that intervene in steering and take over the steering wheel at least temporarily. Examples are lane keeping assist systems (LKAS) or park assist systems.
