The method comprises the following steps: acquiring a self-adaptive cruise input variable; the self-adaptive cruise input variable is input into a torque control model, and the engine torque variation output by the torque control model is obtained; wherein the torque control model is obtained by performing off-line optimization on a previously established radial basis function (RBF) neural network by using an adaptive particle swarm optimization algorithm; and according to the engine torque variable quantity obtained through control, the vehicle is controlled to conduct self-adaptive cruise. According to the method, the RBF neural network is optimized based on the adaptive particle swarm optimization algorithm so as to adaptively adjust parameters, the efficiency and effect of parameter optimization are remarkably improved, the adaptability and reliability of the model are enhanced, adaptive cruise control can be conveniently carried out by using the torque control model obtained through optimization, and the method is suitable for large-scale popularization and application. And the precision and the response speed of adaptive cruise control are improved.
