Hardware-In-The-Loop Testbed and Living Lab for Evaluating Connected and Autonomous Vehicles

Connected and autonomous vehicle (CAV) applications focusing on energy optimization have attracted a lot of attention. However, it is challenging to evaluate various optimizations and controls in real-world traffic scenarios due to safety and technical concerns. In light of this, the authors' previous work has developed a hardware-in-the-loop (HIL) testbed with a laboratory powertrain research platform to evaluate CAV applications. In this work, this HIL testbed is further enhanced to match the performance of an actual testing vehicle and a living lab is developed to incorporate real traffic information. The same engine as the actual testing vehicles at Federal Highway Administration (FHWA) was installed and loaded by a hydrostatic dynamometer whose loading torque is determined by the simulated vehicle dynamics. The vehicle models were calibrated using actual vehicle testing data and the same roadway conditions (such as road slope angles) were input into the testbed. The HIL testbed mimics the performance of a virtual target vehicle and the dynamometer generates the same load as the actual vehicle’s engine is getting. In eight testing scenarios, the results have shown that the performance of the HIL testbed matches very well with the actual testing vehicle with about 1% error. In addition, the HIL testbed’s capability to interact with real traffic was demonstrated through two CAV applications. This is an exciting result since the HIL testbed could provide an effective and economical way for the testing of fuel consumption and emissions on various roadway conditions for autonomous vehicles (AV) and other types of vehicles.
