Testing of automotive park assistant control unit by HIL simulation

Abstract

The paper deals with Hardware in the Loop (HIL) testing of automotive park assistant control unit (PDC). In case of long-term control unit testing it is impractical to use real ultrasonic sensor and manual positioning of the obstacle. Therefore the project is focused on replacement of ultrasonic parking sensors with simulations of their behavior and virtual obstacle simulation with positioning of the obstacle behind the virtual vehicle. In the project four ultrasonic parking sensors of PDC are substitute with HIL simulation which communicates with control unit identically to real sensor during positioning of virtual (simulated) obstacle. The HIL solution was tuned on the project of car Fabia Facelift. Based on the verification of the functionality the HIL simulator is included in the standard test of the vehicle components. © Springer International Publishing Switzerland 2014.
