An Approach to Estimating Acceleration Information for Longitudinal Control

Abstract:

Most of control systems choose velocity and distance as the control parameters for vehicle longitudinal control in the case where no inter-vehicle communication is available and have poor response capability under urgent conditions. The purpose of this paper is to propose new approach to estimating relative acceleration information for vehicle longitudinal control without inter-vehicle communication. Approach is based on design tracking differentiator to filtering and estimating velocity and relative acceleration signal. But for traditional tracking differentiator with many parameters, the trial and error method is adopted in parameters choose process. The number of tracking differentiator parameter is too many to be used effectively in fact. So, new tracking-differentiator with only one parameter is designed in this paper. Theoretical analysis and computer simulation prove that the designed tracking-differentiator can accurately estimate relative acceleration information.
