The invention discloses a vehicle active safety control method and device. A state equation and an observation equation of robust filtering are established to obtain a state vector and an observationvector; filtering recursion calculation is carried out on the state vector and the observation vector to obtain a third vehicle mass and a third road longitudinal slope at the discrete moment; and vehicle active safety control operation is performed based on the third vehicle mass and the third road longitudinal slope at the discrete moment. Through the above scheme, combined estimation of the vehicle mass and the road longitudinal gradient is carried out based on a robust filtering algorithm, so that under the condition of an interference signal, the high-precision vehicle mass and the road longitudinal gradient are accurately obtained in real time; and the vehicle active safety control operation is executed by obtaining the high-precision vehicle mass and the road longitudinal gradient,so that the control effect of the vehicle active safety system is improved. In addition, the application requirements under complex working conditions are met while the vehicle quality and the high precision of the longitudinal gradient of the road are guaranteed.
