Tree-Based Intermittent Connection Fault Diagnosis for Controller Area Network

As the topologies of Controller Area Networks (CAN) in the industrial production systems become increasingly complex, robust and accurate diagnosis of network faults are essential to the system maintenance and reliability assurance. In CAN network, intermittent connection (IC) fault is a hidden problem, which deteriorates the performance and safety of the system. Although IC fault diagnosis methods had been studied, diagnosis of IC faults for CAN network with complex topology has not been systematically addressed. In this paper, a novel IC fault diagnosis methodology for CAN networks with complex topologies is proposed, which utilizes distributed measurement from data link layer information for error pattern analysis. First, the diagnosability of IC faults is defined and the analysis method is presented. Then, local and trunk IC faults localization algorithm is developed based on the integration of error patterns with the network topology. Third, a sequential fault diagnosis strategy is proposed to achieve the full diagnosis of IC faults by gradually compressing the non-diagnosable sub-networks. Testbed is constructed and case studies under various topologies and IC faults scenarios are conducted to demonstrate the effectiveness of the proposed methodology. Experiment results show that the IC faults locations diagnosed by the proposed methodology agree well with the experiment setups.INDEX TERMS Controller area network (CAN), divide-and-conquer fault diagnosis strategy, fault diagnosability, intermittent connection (IC) fault.

In-vehicle communication has become an integral part of today’s driving environment considering the growing add-ons of sensor-centric communication and computing devices inside a vehicle for a range of purposes including vehicle monitoring, physical wiring reduction, and driving efficiency. However, related literature on cyber security for in-vehicle communication systems is still lacking potential dedicated solutions for in-vehicle cyber risks. Existing solutions are mainly relying on protocol-specific security techniques and lacking an overall security framework for in-vehicle communication. In this context, this paper critically explores the literature on cyber security for in-vehicle communication focusing on technical architecture, methodologies, challenges, and possible solutions. In-vehicle communication network architecture is presented considering key components, interfaces, and related technologies. The protocols for in-vehicle communication have been classified based on their characteristics, and usage type. Security solutions for in-vehicle communication have been critically reviewed considering machine learning, cryptography, and port-centric techniques. A multi-layer secure framework is also developed as a protocol and use case-independent in-vehicle communication solution. Finally, open challenges and future dimensions of research for in-vehicle communication cyber security are highlighted as observations and recommendations.

Nowadays, the power consumption and dependable repeated data collection are causing the main issue for fault or collision in controller area network (CAN), which has a great impact for designing autonomous vehicle in smart cities. Whenever a smart vehicle is designed with several sensor nodes, Internet of Things (IoT) modules are linked through CAN for reliable transmission of a message for avoiding collision, but it is failed in communication due to delay and collision in communication of message frame from a source node to the destination. Generally, the emerging role of IoT and vehicles has undoubtedly brought a new path for tomorrow’s cities. The method proposed in this paper is used to gain fault-tolerant capability through Probabilistic Automatic Repeat Request (PARQ) and also Probabilistic Automatic Repeat Request (PARQ) with Fault Impact (PARQ-FI), in addition to providing optimal power allocation in CAN sensor nodes for enhancing the performance of the process and also significantly acting a role for making future smart cities. Several message frames are needed to be retransmitted on PARQ and fault impact (PARQ-FI) calculates the message with a response probability of each node.
