Abstract
Message transmission of CAN bus fixed priority static scheduling algorithm ( FPS) is unpredictable, and low priority message is easily blocked. To solve these problems, a new fixed priority scheduling based on time-triggered architecture (TT - FPS) is presented, and the approach for calculating the worst-case response time of TT - FPS is given. The performance analysis of TT - FPS based on electric vehicle message model is given, and the experiment results prove that the TT - FPS is superior to FPS.
