Can vs LIN bus interfaces in automotive electronics. CAN isn't fast enough for the latest and future automotive networks. • One bit errorin length field circumvents HD=6 CRC FlexRay solves this with a header CRC to protect Length ID ID LEN LEN CRC CRC CRC DATA DATA Original Message Corrupted LEN Source: FlexRay Standard, 2004 With CAN FD, you can send the same data in 1/2 the time as standard CAN, or two times the data in the same amount of time. FlexRay is an automotive network communications protocol developed by the FlexRay Consortium to govern on-board automotive computing. Intrepid has offices in the USA, China, Japan, UK, Germany, India, Korea, and Australia for direct sales and support, as well as a network of distributors. From the systems and design viewpoint the detailed management of sending and receiving CAN messages will normally be done by dedicated hardware, on or off chip, (e.g. Desarrollado por el consorcio FlexRay entre 2000 y 2009. systems Flexray, CAN, LIN, and Ethernet, which offers signal conditioning and the possibility to include user applications. As shown in Table 1, FlexRay’s characteristics suit real-time control functions. In this application note the 5 Series MSO is used to demonstrate decoding and triggering on these buses. The goal of this paper is to provide a valuable resource when comparing and selecting communication protocols for these critical vehicle applications. LIN protocol is a serial wired communication protocol for electronic devices which consist of one master and one or more slaves, but it does support multiples slaves. LIN vs. CAN CAN is more expensive to implement than LIN. The rapid increase of networked electronic control units in airplanes (Line Replaceable Units or Modules, LRUs/LRMs) and automobiles (ECUs) requires to move from CAN buses to higher performance buses. By the way, CatchTheBus not only support CAN and FleRay but also LIN, RS232, Ethernet and Powerline Communication. Consorcio FlexRay Clasificación de los buses de automoción: Non Safety-Critical vs Safety-Critical Event triggered vs Time triggered Algunos buses de automoción: Bus LIN Bus CAN NI-XNET CAN, LIN, and FlexRay interfaces are optimized for applications that require real-time, high-speed manipulation of hundreds of CAN, LIN, and FlexRay frames and signals, such as HIL simulation, rapid control prototyping, bus monitoring, automation control, and more. Almost every important part has tons of sensors on it that has a dedicated computer called ECU (Electrical Control Unit). The above FlexRay waveform is a detail zoom of the FlexRay message and allows the individual state changes to be viewed. FlexRay is a serial communication technology that is used in particular for data communication in very safety-critical use areas in the automobile. Due to the various channel combinations the VN7640 is an ideal interface for laboratory or developer workstation. Introduction. A look at the specifications shows why: In regard to speed, LIN Bus is 40 kbit/sec, CAN Bus is 1 Mbit/sec, and FlexRay is a ten-fold increase, 10 Mbit/sec. Embedded systems applications growing rapidly in the automotive industry. In-Vehicle Network (CAN FD / LIN / FlexRay / Ethernet) protection. CAN vs. FlexRay Length Field Corruptions CAN does not protect length field • Corrupted length field will point to wrong location for CRC! The general trend is that the higher the bandwidth, the higher the cost of nodal implementation. Here we can see clearly that the signals are equal and opposite, and that they are of the same amplitude. Factors that contribute to the higher cost of CAN include: Each node in a CAN network requires a clock generator or crystal; At a silicon level, CAN is more complex to implement; 2-wire transmission is used. It supports Fi-bex and dbc file formats. The table-1 above provides comparison between CAN and TTP interface types. It also provides an interface to HIL systems by Dspace. This enables the mirror image nature of the signals, and the coincidence of the edges to be verified. The FlexRay protocol is a unique time-triggered protocol that provides options for deterministic data that arrives in a predictable time frame. Usually, there are … with CAN, LIN, and FlexRay buses. The received wisdom that LIN is the low cost technology, CAN is the medium cost technology and FlexRay is an expensive technology is too much of a simplification. CAN, CAN-FD, FlexRay and Ethernet cables are used to connect various control devices, sensor units, and multimedia units. If the application requires only one channel, then the second channel can be used for synchronization with the other bus (see Hardware Controlled Synchronization). The expansion to cover LIN and FlexRay testing demands additional intelligent interface instruments, each dedicated to their specific type of bus.
