Power Line Communication standards for in-vehicle networks

International audienceThis paper deals with the in-vehicle networks. We propose to study a network which do not need new wires called Power Line Communication (PLC). Indeed, the automotive communication networks has evolved and the electronic devices in-vehicle are widespread. For example, drive-by-wire systems have actuators, engine, sensor and microprocessor to replace mechanical or hydraulic systems in vehicles. Moreover, electronic control unit (ECU) communicates and exchanges data. These needs of data sharing between ECU or between new services like multimedia involve to research new buses of communication with high throughputs. The CAN, LIN and FlexRay are wire protocols of communication usually used in the same vehicles and FlexRay has the highest throughput (10 Mbps). It appears that with the increase of electronic devices there is a wire harness bottleneck. To reduce wires and to have high throughputs (> 10 Mbps), we propose to study the feasibility of PLC indoor standards in-vehicles. PLC are usually used in indoor networks. In this paper, a comparison of two PLC standards with throughput measurements thanks to commercial PLC modem in-vehicle is carried out: HomePlug Av (HPAV) and High Definition Power Line Communication (HD-PLC)

Survey of Automotive Controller Area Network Intrusion Detection Systems

Novel attacks continue to appear against in-vehicle networks due to the increasing complexity of heterogeneous software and hardware components used in vehicles. These new components introduce challenges when developing efficient and adaptable security mechanisms. Several intrusion detection systems (IDS) have been proposed to identify and protect in-vehicle networks against malicious activities. We describe the state-of-the-art intrusion detection methods for securing automotive networks, with special focus on the Controller Area Network (CAN). We provide a description of vulnerabilities, highlight threat models, identify known attack vectors present in CAN, and discuss the advantages and disadvantages of suggested solutions

A Validity of in-Vehicle Networks Using CAN-FD

The most common communication interface for automotive electronic control units is CAN (Controller Area Network). Since CAN was first introduced in Daimler vehicles in 1991, all automotive manufacturers have adopted CAN communication for in-vehicle networks. However, as the number of electronic control units connected to the CAN network grows rapidly, the CAN protocol is reaching its technological limits. To overcome this limitation, Bosch has introduced a new communication protocol, CAN-FD (Flexible Data-rate). In this paper, we analyse the characteristics and limitations of CAN-FD communication according to the topology under the in-vehicle wiring harness environment designed based on the existing classic CAN communication
