Abstract: | With the advantages of independent control of each wheel and fast torque response, distributed drive electric vehicles (DDEVs) can significantly enhance vehicle handling stability, safety and economy.However, the vehicle is a nonlinear and strongly coupled system, facing the challenges such as coupling of each controller and the over-actuated system with complexity and uncertainties, which requires multi dimensional (longitudinal, lateral and vertical) integrated control and fault-tolerant control. In this paper, the key technologies and development status of distributed drive electric vehicles are reviewed from the traditional single-dimensional control to multi-dimensional integrated control. The multi-layer structures of vehicle dynamics integrated control, especially the integrated control of longitudinal-lateral-vertical
dynamics, are introduced and their applications are summarized. Finally some suggestions are put forward on the future development direction of the dynamic control system of distributed drive electric vehicles. |
