英文摘要
      A novel integrated lateral and longitudinal control method consisting of an upper coordinated control law and a lower control allocation law, is developed for the intelligent electric vehicles with high nonlinearity, strong coupling and redundancy. Firstly, a dynamical model which can accurately reflect the behavior and mechanism of intelligent electric vehicles is built. Secondly, an upper coordinated control law which can effectively tackle with the nonlinear and uncertain characteristics is designed by non-singular terminal sliding mode technology, and the finite-time convergence of the system states is guaranteed. On this basis, considering the redundant and coupled properties of tires, a lower control allocation algorithm based on interior point method is proposed to optimally allocate the expected generalized forces/moment through coordinating and reconstructing the lateral and longitudinal tire forces. Simulation results are provided to demonstrate the effectiveness of the proposed strategy.
