This paper approaches the use of Hardware-in-the-Loop (HiL) test framework to perform automated verification test of Seatbelt Reminder Function in automotive Instrument Panel Cluster (IPC). The goal of this test was to verify if the Belt-Minder™ Feature performs its seatbelt warning function sounding a chime and illuminating a warning light when the user has his seatbelt unbuckled in compliance with safety standards and regulations. The manual execution of this test requires many resources like prototype vehicle, fuel, many engineers' work hours for each test, etc. However, testing dynamically with HiL system some of those mentioned resources are not required like the prototype vehicle and other are reduced, for example, the time taken to have report on hands. The most important among the advantages, was the possibility of testing with HiL earlier in the V-Diagram. The complexity of testing the IPC dynamically (automatic) was because this module provides most of the available and important information to the users about the overall status of the car. All information traffic comes to IPC by hardwired or CAN (Controller…
