The Internet of Vehicles is essential for building smart cities. By analyzing the big data collected by vehicle sensors on the road, we can estimate vehicle information and real-time road conditions. To improve the prediction accuracy, this paper proposes a new adaptive filtering algorithm for variable measurement noise problems that occur during the driving state estimations of two-axle electric vehicles. Based on the nonlinear three-degree-of-freedom vehicle model, the dual-motor torque output model, and the Dugoff tire model, fuzzy logic is used to correct the measurement noise in the cubature Kalman filter algorithm. Moreover, the ant colony algorithm is used to optimize the input and output membership functions. Based on the big sensor data, we can accurately predict road conditions, such as vehicle speed and road adhesion coefficients. The simulation results based on CarSim/Simulink show that the new algorithm improves the estimation accuracy of the whole system, regardless of whether the measurement noise is fixed or variable. The research in this paper provides a reference for multi-data comprehensive analyses under different vehicle states. |
