In this paper, new estimation methods for vehicle tire steering angles were proposed to improve the accuracy of a vehicle lateral model. There are several error factors in the conventional, single-track model as a result of certain assumptions in the derivation process. The front and rear steering angles can be considered influential input signals to a vehicle lateral model, as well as very large error factors. In conventional vehicle models, the steering angles are determined only by the driver’s steering angle. However, in the real world, they are also affected by roll steer and compliance steer. Therefore, the proposed methods, in which roll and compliance are considered, were developed efficiently in the form of an open-loop model by using a lateral acceleration sensor measurement signal. The proposed steering angle estimation models are validated through CARSIM simulations and real-vehicle experiments under different driving conditions. |
