Heavy truck and bus manufactures in automotive applications extensively use the SAE J1939 protocol definition. In this paper, the SAE J1939 protocol base on CAN bus was discussed. The real-time parameter is a key point of protocol's performance evaluation. The most important thing is to give an effective and reasonable method to simulation. Based on the analysis of the Data Link layer of CAN bus protocol,...
Tracking reentry vehicle with strong maneuvers on-line is a challenging task. The key is to develop suitable dynamic models and estimation methods. Two kinds of modeling methods are discussed for reentry tracking, and the unscented filter (UKF) is introduced to the nonlinear tracking system. To reduce the computational load, three simplifications of UKF are developed. Furthermore, the feasibility...
