Title:
METHOD AND APPARATUS FOR CONSTRUCTING VEHICLE DYNAMICS MODEL, DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/082213
Kind Code:
A1
Abstract:
The present application is applied to the technical field of automobiles, and disclosed thereby are a method and apparatus for constructing a vehicle dynamics model, a device, and a storage medium. The vehicle dynamics model constructed by the present application comprises a tire data model, a tire mechanism model, and a whole vehicle dynamics model. The construction method comprises: acquiring real vehicle driving data of a vehicle under a first driving control parameter; inputting the first driving control parameter into the tire data model and the tire mechanism model, respectively, and obtaining first tire stress data and second tire stress data; fusing the first tire stress data and the second tire stress data, and obtaining fused tire stress data; inputting the fused tire stress data into the whole vehicle dynamics model, and obtaining simulated driving data; and according to the simulated driving data and the real vehicle driving data, performing parameter adjustment on the tire data model. By using the present application, a vehicle dynamics model that can accurately reflect the dynamic performance of a vehicle can be constructed.
