Abstract：To solve the problem that existing estimation strategy of side slip angle based on steering wheel angle signal was not suitable for the interference of active steering, according to the structural characteristics of pinion angle sensor and rackpinion steering gear equipped in active steering, an estimation strategy was proposed with the consideration of side slip angle as a nonlinear mapping of time series of pinion angle and lateral acceleration. To verify the effectiveness of the proposed estimation strategy, double lane change and slalom virtual tests were conducted based on the simulation platform of CarSim. The virtual tests data were used to train and verify the estimation algorithm based on adaptive neurofuzzy inference system, and the performance of the two estimation strategies was compared under the situations with and without interference of active steering, respectively. The results indicate that the proposed estimation strategy is still effective for the side slip angle with interference of active steering.
