“…Since this technique require changes at the physical layer hence can be achieved using programmable logic devices (PLD's) such as FPGA's. Recent prototype implementations have been described by Sheikh & Short [3] and Ziermann et al [7]. The controller described by [3] follows a close implementation of [6]; however the implementation described in [7] differs in several key aspects.…”

The CAN protocol was originally introduced for distributed automotive applications in the 1980s, and is still widely used by the industry today. CAN provides the basis for many cost-effective distributed systems, and since its first inception has proved to be a continuous area of research. One major drawback that can severely limit the applicability of CAN in data-intensive real-time applications is related to the wired-AND nature of the physical layer that is used to manage message arbitration; a side effect of this is that it acts to severely limit both the maximum transmission speed and bus length of a given CAN network. This paper is concerned with over-clocking a CAN network to improve the data rate and information throughput, whilst simultaneously maintaining the priority-driven arbitration mechanism that is a major beneficial feature of the protocol. The paper will first describe briefly an already existing implementation of an overclocked CANcontroller done by the authors in a previous work. The paper then presents an analysis as to its expected performance in realtime applications. Specifically, the paper discusses the calculation of message transmission times, investigates the effects of the technique on message transmission jitter, and potential effects on the expected bit error rate.

“…Multiplications of two binary variables in Equations (4), (14), (15), (20), and (24): if α and β are binary variables and α × β exists in a constraint, then we replace α × β by a binary variable γ in the constraint and add one constraint: α × β = γ. Next, α × β = γ can be replaced by equivalent constraints:…”

Abstract-Cyber-security is a rising issue for automotive electronic systems, and it is critical to system safety and dependability. Current in-vehicles architectures, such as those based on the Controller Area Network (CAN), do not provide direct support for secure communications. When retrofitting these architectures with security mechanisms, a major challenge is to ensure that system safety will not be hindered, given the limited computation and communication resources. We apply Message Authentication Codes (MACs) to protect against masquerade and replay attacks on CAN networks, and propose an optimal Mixed Integer Linear Programming (MILP) formulation for solving the mapping problem from a functional model to the CAN-based platform while meeting both the security and the safety requirements. We also develop an efficient heuristic for the mapping problem under security and safety constraints. To the best of our knowledge, this is the first work to address security and safety in an integrated formulation in the design automation of automotive electronic systems. Experimental results of an industrial case study show the effectiveness of our approach.

“…However, limitation of the topology to PtoP and modification to the controllers are necessary, which makes the protocol significantly different from CAN. In addition, the method to speed up part of frame which does not participate in arbitration and reply of ACK is suggested [8] - [10], but change in the controllers is necessary for this method. Therefore, the suppression of waveform ringing is effective to speed up CAN communication without changing the existing controlling hardware and software drastically.…”

As the number of ECUs in an automobile steadily increases, the demand for ever more ECUs connected to the Controller Area Network (CAN) also rises significantly. However, the number of connectable ECUs in a linear passive star CAN is restricted because of the ringing phenomenon in communication signals. In this paper, we propose a ringing suppression circuit activated on high level ringing voltages. As a result, we can expand the number of connectable ECUs in a linear passive star, which enables construction of low-cost communication networks by reducing the number of gateways required
