Vehicle stability optimization method and device based on sensitivity analysis and medium

The invention relates to the technical field of data processing, and discloses a vehicle stability optimization method and device based on sensitivity analysis and a medium, and the method comprises the steps: determining each initial sampling value of each design variable in a vehicle suspension through an initial sampling number, and inputting each initial sampling value of each design variable into a suspension simulation model; obtaining each initial output value of each performance parameter, further determining a sensitivity analysis value between each design variable and each performance parameter, determining a variable to be rejected in all design variables in combination with the sensitivity analysis value, rejecting the variable from the design variables, and determining a final sampling number of each design variable; the stability objective function is optimized and solved based on the final sampling number of each design variable, the optimization value of each design variable is obtained, the p
