Automotive functional safety

If you are an SW SEooC developer, how do you know if you have sufficiently verified your SW? Our 2 -part videos will help you get an answer to this question. If you are new to SEooC, check out our earlier article .

If you are someone who has been working in the Automotive domain in various ECUs like power train ECUs, Infotainment, Instrument clusters, Body control etc and you are now getting started in the world of ADAS (Advanced Driver Assistance Systems), this article is for you! ADAS is the way to go for automotive innovation in this decade and THE Safety solution for lesser car accidents on the road. We have compiled here some extremely good articles and videos that can help you get started in ADAS. Read, Watch them. Have fun learning!!

In our previous blog, we introduced you to the first 5 Safety highlights of Adaptive Autosar. In this blog, let us discuss the remaining 6 highlights. 6. Safe Service oriented Communication HAD use cases demand dynamic upgrade of software applications throughout the entire vehicle lifecycle and to subsequently add new software functions, for instance via over-the-air software updates. Applications may be developed and tested independent of each other in distributed working groups and then integrated into the overall system at any time. Using Service-oriented communication between the software applications makes this possible. Service-Oriented Communication (SoC) is the main communication pattern for AA Applications. The concept of service-oriented communication is based on the idea that there are applications that provide a service on the communication system and other applications subscribe to this service.  The data will only be sent to the subscribers. Here is a picture from Autosar

In our previous blog , we introduced you to the 11 Safety highlights of Adaptive Autosar. In this blog, let us discuss the first 5 highlights. 1. Safety considerations for high performance oriented hardware While CA is targeted to run on Microcontrollers that offer hard real time performance, Adaptive AUTOSAR Platform is targeted to run on complex SOCs with hardware accelerators such as accelerators for advanced graphics processing, deep learning accelerators, DSPs, Multi-cores etc in order to achieve high performance. Obviously, this means that there is a lot of concurrent processing going on. To achieve deterministic execution for Safety functions, AA provides design guidelines for using parallel processing technologies .  An ASIL compliant Hypervisor must be used to partition and isolate the Safety critical aspects of the System from the non-Safety related System. 2. Support for Safe and Secure use of C++ While the CA supports only C language, AP support C++ since it is the language

  Adaptive AUTOSAR (AA) is the buzz word in the context of highly automated driving (HAD). It is the AUTOSAR consortium’s solution for high performance computing and flexible over-the-air updates in HAD and also other ECUs such as Domain Controllers, Infotainment systems etc.  While Classic AUTOSAR (CA) offers an excellent solution to handle traditional ECUs with deeply embedded software and hard real time requirements, it cannot handle HAD and other such intelligent ECUs because its design does not support the high performance and flexibility requirements of these ECUs. This sprung the need to develop a new platform for such ECUs and thus was born AA. An OEM or Tier-1 chooses AA so that they do not have to reinvent the wheel for an architectural solution for the Intelligent ECUs. Due to the safety criticality of these Intelligent ECUs, AA incorporates several safety aspects as part of its architecture. In this blog, we have highlighted 11 of the key differentiating aspects.  However,
