Model-based design and testing for electric vehicle driveability analysis

In this paper a model-based design and testing method focusing on the electric vehicle driveability aspect is proposed. The design approach is divided into two steps. The first step is the Model-in-the-Loop co-simulation coupling a vector-controlled electric drive modelled in MATLAB/Simulink to a planar forward-facing electric vehicle LMS Imagine. Lab Amesim model. The second step represents a mechanical-level Hardware-in-the-Loop test for a physical electric drive that integrates the electric vehicle model in the real-time testing case. Two different sampling times of the vehicle control unit are considered and their influence on the vehicle responsiveness and on the longitudinal jerk acting on the driver is analysed through both offline simulation and real-time testing.
