Cambustion has introduced a Powertrain in the Loop (PiL) testing platform at its Hub Dyno facility in Cambridge, UK. The system allows automotive OEMs to integrate and validate vehicle components before a physical prototype is ready. The platform relies on a 12-month development program that initially supported the creation of a hybrid supercar.
The PiL setup combines real hardware with simulated subsystems using Hardware-in-the-Loop (HiL) technology. This enables engineers to test control strategies and system performance in real time. For high-voltage testing, the facility includes a 1,100 V, 500 kW battery simulator, which can replace a physical battery during the development process.
The testing environment connects directly to wheel hubs for powertrains already installed in a chassis. Dynamometers replicate transient conditions, including legislative drive cycles and torque vectoring. Additionally, the test cell features temperature control capable of operating down to -15 degrees Celsius to assess system robustness.
According to Cambustion director Bruce Campbell, the platform allows for parallel development, where engineers can debug and optimize systems while the vehicle build continues. Following the initial prototype availability, manufacturers can transition to a 4WD Chassis Dyno or continue using the Hub Dyno PiL alongside on-road testing.
