Use of dynamic emulation of mechanical loads in the testing of electrical vehicle driveline control algorithms

An approach using dynamic emulation of mechanical loads for testing and validation of the electrical vehicles' drivelines will be presented in the paper. It has been designed to enable the evaluation of the electric drive behavior also in the case of rapid speed and torque changes. Dynamic emulation of mechanical loads is a Hardware-in-the-loop (HIL) procedure, which can be used as a supplement of the conventional simulations in testing of the operation of algorithms without the need for the prototypes. Parts of actual system are replaced by the mathematical models, which are numerically calculated on-line and connected to the actual components of the system by the use of software and hardware interfaces. The performance of the proposed method is investigated and verified experimentally on dSPACE system.
