Dynamic Test Scheduling in Hardware-In-the-Loop Simulation of Commercial Vehicles
<p> <p>Modern day commercial vehicles are controlled by various Electronic Control Units (ECU). They are not only tested as single units, but also by networking them in Controlled Area Network bus (CAN) to form a complete electrical control system. This is achieved using Hardware In the Loop (HIL) …
