Controller Area Network (CAN) is the most widely used field bus protocol in the automotive domain. The development process of today's cars follows the well established automotive V-Model. Traditional bus-based CAN makes the development an ever increasing challenge. For example, the introduction of a single additional CAN message influences the timing of already existing messages and thereby increases...
The time-triggered router for CAN has as its goal to improves the dependability, performance and timeliness of CAN communication. The configuration of the CAN router includes knowledge about the permitted behavior of nodes in the time and value domains. Based on this configuration the CAN router performs fault isolation, diagnosis, message multicasting and message transformations. This paper presents...
Controller Area Network (CAN) is the most widely used protocol in the automotive domain. Bus-based CAN does not provide any security mechanisms to counter manipulations like eavesdropping, fabrication of messages, or denial-of-service attacks. The vulnerabilities in bus-based CAN are alarming, because safety-critical subsystems (e.g., the power train) often deploy a CAN bus, and hence a failure propagation...
The dependability deficiencies and bandwidth constraints of the controller area network (CAN) can prevent its use in safety-relevant and performance-demanding applications. This paper introduces mechanisms for fault detection and fault isolation based on an intelligent CAN router, which exploits a priori knowledge about the permitted behavior of attached electronic control units (ECUs) in order to...
