Modular vehicle in the loop

Abstract

Most vehicle controllers are developed and validated with V-model. The model in the automotive industry has some traditional methods called “X-in-the-loop(XIL).” The validation of the advanced driver assistance system(ADAS) controller, however, is more complicated and needs more environmental resources because the controller interacts with the external environment of the vehicle. Vehicle-in-the-loop(VIL) is a recently developed approach for ADAS vehicle simulation that ensures the safety of critical test scenarios in real-world testing with a virtual environment. This paper presents a new architecture for modular vehicle-in-the-loop(M-VIL), which contains four parts: a sync module, a virtual environment, sensor emulators, and visualizers. Each part can be developed and modified separately and in combination with the other parts. The structure of M-VIL is expected to save on maintenance time and cost. This paper also shows its acceptability by testing ADAS on both a real system and the VIL system.
