Vehicle performance parameter determination method and device, computer equipment, readable storage medium and program product

The invention relates to a vehicle performance parameter determination method and device, computer equipment, a computer readable storage medium and a computer program product. The method comprises the steps of obtaining preset sprung mass and preset spring stiffness of a hydro-pneumatic spring, and inputting the preset sprung mass and the preset spring stiffness into a simulation model of a vehicle hydro-pneumatic suspension system; functional requirements for the hydro-pneumatic spring are obtained, analog simulation is carried out in the simulation model based on the functional requirements and preset simulation input parameters, and initial values of various performance parameters of the vehicle hydro-pneumatic suspension system at each moment in the analog simulation process are obtained; and for each performance parameter, under the condition that the initial value of each moment in the analog simulation process is within a preset value range corresponding to the moment, determining the initial value as
