This work consists of the development of a vehicle emulator for testing electric vehicle drivetrains. The vehicle emulator consists of two mechanically coupled electrical machines. One is acting as the traction machine of a certain car and the other is acting as a load machine which mimics the torque of road behaviour according to the parameters of a certain car. These parameters include the rolling resistance, the aerodynamic drag, the inertia of the whole car and the slope of the road. Tests can be performed according to official test drive cycles as the NEDC or the WLTP or by self-imported drive cycles. The characteristics of both machines were measured and a model was made for each machine in its operating mode. A software interface was designed using LabVIEW from National Instruments, so that the setup can be easily controlled and all electrical and mechanical quantities can be logged. The machines are controlled via a dedicated real time controller, the CompactRIO from National Instruments. This controller receives as input all electrical quantities of both machines. From these electrical quantities the speed and torque of the setup are estimated. The vehicle emulator can thus operate without the need of a torque transducer or tachometer.
