Title:
ECONOMICAL OPTIMIZATION POLICY CONSTRUCTION METHOD FOR LATERAL STABILITY CONTROL OVER ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/240760
Kind Code:
A1
Abstract:
An economical optimization policy construction method and system for lateral stability control over an electric vehicle, and a computer-readable storage medium. The method comprises: firstly, constructing a lateral stability control system model which includes active distribution optimization, and realizing coordinated distribution of effective operating intervals of all parts by means of a coordination variable L; secondly, on the basis of the system model including the active distribution optimization, designing a lateral stability controller under a model prediction control framework, wherein a designed objective function J enables a motion state of a vehicle to track an expected value in a steady state, and an objective function Je is used for torque distribution; finally, in consideration of a mapping relationship between an additional yaw moment output by the controller and the coordination variable L, constructing a three-dimensional spatial curved surface; analyzing the effect of the coordination variable L on the overall efficiency of a hub electric motor; and determining a workflow of an adjuster for the coordination variable L, thereby improving the overall efficiency of the hub electric motor.
