The invention particularly relates to a carbon fiber composite laminate generation method, a carbon fiber composite laminate and an automobile. The method comprises the following steps: determining the respective layer number and position relation of carbon fiber layers and steel layers; taking the thickness of the carbon fiber layer and the thickness of the steel layer as variables, and taking the minimum total mass of the carbon fiber composite laminates as a target to construct a corresponding target function; then constructing a constraint function corresponding to the carbon fiber composite laminate according to the strength and rigidity requirements of the steel plate layer in the actual application working condition; solving the multi-objective optimization model to obtain the optimal thickness of the carbon fiber layer and the optimal thickness of the steel layer; and stacking the carbon fiber layers and the steel layers together based on the respective layer number, the position relation and the optimal thickness of the carbon fiber layers and the steel layers to generate corresponding carbon fiber composite laminates. According to the method, the total mass of the carbon fiber composite laminate and the strength and rigidity requirements of the carbon fiber composite laminate under the actual application working condition can be comprehensively considered, so that the actual application effect of the carbon fiber composite laminate can be ensured while the lightweight design of the carbon fiber composite laminate is realized.
