Electronic control systems play a significant part in the performance enhancement and safety of modern machinery. On the modern passenger car, for example, such systems include ABS (Active Braking System), TCS (Traction Control System), DSC (Driver Stability Control), ARC (Active Roll Control) to name but few. Development and testing of these controls systems, particularly under extreme conditions (cold climate), can be expensive, time consuming and often seasonal. Hardware in the Loop (HIL) offers a cheaper, faster and more efficient means of testing such systems. This is achieved by connecting the actual onboard electronics inline with a real time computer model. In the case of the passenger car, the computer model would be of the car and the actual electronics could be the DSC system, for example. The model would then be made to simulate required performance and safety manoeuvres in order that the DSC system can be developed and tuned. The process can be performed at any time, in any location, in any climate. Thus long lead times and associated costs caused by winter testing, for example, can be avoided or significantly reduced. MVP currently offers an HIL solution through the German company IPG. IPG has twenty years of experience in offering automotive HIL solutions to companies such as Ford, Volkswagen, TRW, GM and PSA Peugot Citroen.
