SYSTEM FOR TESTING AND EVALUATING THE BEHAVIOUR AND ENERGY EFFICIENCY OF THE DRIVE SYSTEM OF A HYBRID-ELECTRIC MOTOR VEHICLE

摘要

The system allows a quasi-realistic evaluation of different architectures/operating modes (strictly electric, series, parallel, parallel-series, electric+range expansion) and the evaluation of energy management and regenerative braking management strategies. The testing system comprises two electric machines that can be mechanically coupled to the internal combustion and electric machines of the hybrid-electric drive system; an electric energy conversion device which allows controlling and reproducing the different operating modes, power distributions and architectures of the hybrid-electric drive system; an emulation device DVE (vehicle-environment-driver) in real time controlling and managing the system and including models emulating the dynamic performance of the vehicle, including the mechanical transmission and coupling systems thereof, the performance of the conventional brake (ABS) system, the performance of a driver, and the driving environment; an interface device which allows the interconnection of the emulation device DVE with the energy management, brake management and control panel management subsystems of the hybrid-electric drive system.
