ESC on In-Wheel Motors Driven Electric Vehicle: Handling and Stability Performances Assessment

Improved lateral stability performances of modern Electric Vehicles equipped with In-Wheel Motors could be achieved by a proper design of the adopted control strategy. The possibility to independently regulates braking and traction efforts delivered at each wheel can lead to increased handling properties during cornering manoeuvres, especially if performed in degraded adherence operative conditions. In this activity, authors propose a newly ESC lateral stability algorithm, integrated with longitudinal stability controller (EBD and ABS) and implemented on a benchmark vehicle use case model. The assessment of the performances is done through co-simulation activities, imposing to the vehicle specified reference trajectories according to related standards, in order to evaluate the achieved stability improvements.
