For the development of modern vehicle dynamics controllers (VDCs), hardware-in-the-loop (HIL) systems are indispensable. HIL simulation can be regarded as a standard methodology today, because these multi-sensor and multi-actuator electronic control units (ECUs) are extremely safety critical. This paper aims at providing a comprehensive technical overview of state-of-the-art HIL test systems for VDCs, which are currently widely used in passenger cars, in the form of ABS and ESC. A description of the currently used I/O interface of the VDC ECUs is presented. In order to close the loop, a model of the complete vehicle is required to provide consistent and precise sensor signals as a response to the current actuator and (simulated) driver input signals. In the last section of the paper an example of a HIL system for one VDC module is presented, furthermore the interactivity of systems with VDC and adaptive cruise control (ACC) is discussed. This will show how demanding todays chassis controls are and how HIL technology copes with these challenges.
