The invention discloses a distributed
electric drive vehicle multi-performance optimization
torque distribution method. A MPC controller based on an improved C / GMRES
algorithm is adopted to conduct multi-performance optimization
torque distribution. The multi-performance optimization
torque distribution method comprises the steps that a longitudinal total driving torque and a yawing torque given by an upper controller are used as the torque
distribution control input by the MPC controller, tire related information fed back from the vehicle is combined, a model is updated based on the wheel rotation dynamics and the tire
slip rate state, the physical characteristics of the output torque of a hub motor are considered, the
wheel load rate is taken as the stability constraint
precondition, minimizing of the tire slip dissipation energy is taken as the optimization objective, the MPC
optimal control problem is established, the improved C / GMRES
algorithm is adopted to solve the problem of the
torque optimization distribution quickly, and thus the real-
time optimal control of vehicle stability and economy is achieved. According to the distributed
electric drive vehicle multi-performance optimization torque
distribution method, the MPC controller based on the improved C / GMRES
algorithm is adopted to conduct multi-performance optimization torque distribution, the tire slip dissipation energy is minimized on the
precondition of ensuring the vehicle stability, and the algorithm has high computational efficiency and is suitable for real-time application.
