“…Tindell's seminal research heavily influenced the design of on-chip CAN peripherals such as Motorola msCAN (Motorola, 1998) and has lead to a large body of work into schedulability theory and error models for CAN (Punnekkat et al, 2000;Nolte et al, 2002Nolte et al, , 2003Broster et al, 2002Broster et al, , 2005Hansson et al, 2002;Broster and Burns, 2003), including at least two PhD theses (Broster, 2003;Nolte, 2006). Overall, this research into CAN scheduling has been cited in over 200 2 subsequent papers.…”

Controller Area Network (CAN) is used extensively in automotive applications, with in excess of 400 million CAN enabled microcontrollers manufactured each year. In 1994 schedulability analysis was developed for CAN, showing how worst-case response times of CAN messages could be calculated and hence guarantees provided that message response times would not exceed their deadlines. This seminal research has been cited in over 200 subsequent papers and transferred to industry in the form of commercial CAN schedulability analysis tools. These tools have been used by a large number of major automotive manufacturers in the design of in-vehicle networks for a wide range of cars, millions of which have been manufactured during the last decade. This paper shows that the original schedulability analysis given for CAN messages is flawed. It may provide guarantees for messages that will in fact miss their deadlines in the worst-case. This paper provides revised analysis resolving the problems with the original approach. Further, it highlights that the priority assignment policy, previously claimed to be optimal for CAN, is not in fact optimal and cites a method of obtaining an optimal priority ordering that is applicable to CAN. The paper discusses the possible impact on commercial CAN systems designed and developed using flawed schedulability analysis and makes recommendations for the revision of CAN schedulability analysis tools.

“…The CAN communication protocol is widely used in the automotive sector. Although the CAN protocol was originally developed as a communication protocol for vehicles, it has also been used commonly used in industrial control, robot technology, and medical appliances due to its high performance (it allows the transmission of 10,000 messages in 1 s) and reliability [11]. It has been determined, as a result of statistical probability calculations, that only one undetected message error could be committed in a century [12].…”

Abstract:In this study, the aim was to lift loads that required more force using the infrastructure of existing vehicles.To this end, a truck-mounted diesel engine was selected to be used in mobile crane applications. A control system was designed and implemented to obtain the appropriate hydraulic force by accessing the diesel engine with a controller area network bus via an electronic control unit (ECU). For this purpose, hydraulic pumps to be used to operate the crane were mounted on the selected mobile diesel engine with an ECU. Firms that manufacture cranes in the world produce cranes with infrastructure. This study was conducted in order to mount a telescopic crane that has a capacity to lift 50 t (with a radius of 3 m) on vehicles with standard infrastructure in Turkey. The other aim of this study was to determine the transactions that the crane operator made during operation in the past and log these data.

“…By coupling bit-wise arbitration and schedulability analysis, hard real-time constraints can be satisfied when traffic patterns (period, payload size, and deadline of all data streams) are known in advance [5]- [8]. However, CAN proves to be very suitable for the use in soft real-time systems as well, including those which actually have no real-time constraints.…”

Abstract-Thanks to its distributed and asynchronous medium access control mechanism, CAN is the ideal choice for interconnecting devices in event-driven systems. When timing requirements of applications are not particularly demanding, as in the case of, e.g., reactive and proactive maintenance, constraints on event delivery can be relaxed, so that their notification may rely on best-effort approaches.In this paper, a number of techniques are taken into account for notifying events in such a kind of systems, and their performance has been evaluated. Besides conventional CAN, a recent proposal for extending this protocol, termed CAN XR, is considered. Moreover, the adoption of Bloom filters to cope with rare events in very large systems has also been evaluated.
