This paper presents a novel hierarchical stability control providing modified control target for distributed drive intelligent electric vehicle through preview characteristics. For the upper layer, the classical bicycle model is employed to develop the desired vehicle states. Preview model is built to amend the former states, thereby formulating a modified control target since the intelligent electric vehicle is able to predetermine the driving behavior. The direct yaw moment is then designed to manage the vehicle motion according to the modified target. For the lower layer, considering the road condition, longitudinal force is encouraged to allocated on each driving wheel for generating direct yaw moment so as to enhance the vehicle stability performance. To validate the preview-based control in terms of intelligent electric vehicle stability, the designed longitudinal force is calculated and fed to the test vehicle established with A&D5435 rapid prototyping platform. The test results show that the stability control with the modified control target can significantly reduce the lateral sideslip angle and lateral acceleration on different roads, which contribute to enhancing vehicle stability.
