Vehicle cornering stiffness determination method and device, computer equipment and storage medium

The invention relates to a vehicle cornering stiffness determination method and device, computer equipment, a storage medium and a computer program product. The method comprises the following steps: acquiring basic parameter information of a to-be-measured vehicle, and establishing a cornering stiffness recursion model of the to-be-measured vehicle based on the basic parameter information; according to the cornering stiffness recursion model, randomly setting different working conditions, and collecting tire cornering stiffness of the vehicle and corresponding vehicle state information under each working condition; based on the tire cornering stiffness and the corresponding vehicle state information under each working condition, training a preset prediction model until the preset prediction model converges; and according to the real-time vehicle state information of the to-be-measured vehicle and the converged preset prediction model, predicting the real-time tire cornering stiffness of the to-be-measured veh
