Abstract
A method for integrated control of handling stability of a distributed drive electric vehicle is provided, in which a Magic Formula tire model is subjected to piecewise linear fitting to obtain a piecewise affine tire model; a hybrid logical dynamic model is established based on the piecewise affine tire model; a hierarchical integrated control strategy is adopted to obtain an upper-layer hybrid model predictive controller and a lower-layer four-wheel torque optimal allocation controller, so as to calculate an additional yaw moment, an additional front-wheel steering angle and a wheel drive torque. Related devices for implementing the integrated control method are also provided.
