Distributed Validation and Testing of EV Systems

The presented study addresses the methodology for building distributed test platforms that support the design of electric vehicle (EV) systems and the validation of their functionality. The platforms are implemented in the form of an X-in-the-loop (XIL) architecture and may include multiple test setups united in a local or geographically remote network. The communication of the networked test setups is based on the User Datagram Protocol (UDP). The paper presents the realization of the XIL environment suitable for the development of EV control systems such as brake blending, ride blending (RB) and integrated chassis control (ICC). For this purpose, the dynamometric test setup for the in-wheel motor, the hardware-in-the-loop (HIL) brake test bench, the shaker for the suspension actuators, and the driving simulator are integrated into the XIL environment. The results show the validation of the controllers for several complex maneuvers.
