摘要：Controller Area Network (CAN) is widely used highly in automotive implementations; with in surplus of 5 00 million CAN sanctioned microcontrollers manufactured per year. In the year of 1994 schedulability analysis was developed for CAN (Controller Area Network) , showing how worst - case response times (wcrt) of CAN messag es could be deliberate and prove assurance prov ided that message response time would never pass their deadline . This main fact - finding has been exhibit sch edulability response time in case of worst - case response time analysis . These tools have been used by a large number o f major manufactures for automotive in the design of in - vehicle lattice for a wide range of cars and heavy vehicle millions of which have b een manufactured over the last 6 years. In this paper we work on execution of data by using less clock cycles, which uses less response time to execute data to transmission. Through this paper we showed that the original schedulabi lity analysis given for CAN ( Controller Area N etwork) messages is imprecise. It should gives assurance for messages that will in fact miss their deadlines in the worst - case response time analysis . In this paper pr ovides re - evaluate analysis reconcile the problems with the genuine method . The paper explore the possible effect on commercial CAN systems designed and developed using imprecise schedulability analysis and makes exhortation for the revision of CAN schedulability analysis t ools. The expand use of electronic components in today's automobiles need more powerful in - vehicle lattice communication protocols.
