In view of the large calibration workload of existing models, this paper proposes a compound correction method based on the principle of compound correction control; this method takes open-loop correction as the main body, which represents the driver’s mastery of vehicle dynamics characteristics; on this basis, a closed-loop correction is added to describe driver’s compensation and correction capabilities. Considering the complexity of the longitudinal force of the vehicle, based on the analysis of the longitudinal force of the vehicle, considering the actual situation of the actual driver’s foot switching between the accelerator pedal and the brake pedal, a longitudinal dynamics split-phase correction method is proposed. In addition, this paper proposes a fast calibration method of the inverse model of the main characteristics of vehicle dynamics, which mainly studies the fast calibration method of the main characteristics of braking dynamics and lateral dynamics in order to reduce the time cost. The simulation shows that the compound correction model proposed in this paper not only has a small calibration workload and high control accuracy, but also has a certain adaptive ability to the nonlinear characteristics of vehicle dynamics; the main characteristics of braking dynamics and lateral dynamics proposed in this paper has high accuracy.
