Abstract A key feature achievable by electric vehicles with multiple motors is torque-vectoring. Many control techniques have been developed to harness torque-vectoring in order improve vehicle safety and energy efficiency. The majority of the existing contributions only deal specific aspects This paper presents an integrated approach allowing a smooth coordination among main blocks that constitute framework: (1) reference generator, defines target yaw rate sideslip angle; (2) high level controller, works out required total torque moment at level; (3) low maps force into individual wheel demands. In this framework, driver can select one number driving modes allow change cornering response and, as second priority, maximise For first time, selectable include “Energy efficiency” mode uses prioritise maximisation efficiency, thus further increasing range. Simulation results show effectiveness proposed framework on experimentally validated 14 degrees freedom model.
