Interview Questions on AUTOSAR
AUTOSAR is used for providing intrinsic advantages to the associates to handle more complex electrical and electronic systems in a vehicle like simple integration, switch the functions within complex engine control (ECU) network & to control over the lifecycle of the whole product. It is also used for microcontrollers which target applications mostly in automotive space which utilizes CAN, Flex Ray, Ethernet, etc. Being used in applications based on microcontrollers, it is developed with a view to using the least memory possible as microcontrollers have resource constraints.
AUTOSAR ECU is used to create and establish an open and standardized software architecture for automotive electronic control units (ECUs). It has some goals such as scalability to different vehicle and platform variants, transferability of software, the consideration of availability and safety requirements, a collaboration between various partners, sustainable use of natural resources, and maintainability during the whole product lifecycle. AUTOSAR Architecture was introduced to promote standardization in the software development process of Automotive Electronic Control Units (ECU).
ComStack stands for Communication Stack. In the AUTOSAR layered architecture, Communication Stack or ComStack facilitates vehicle network communication. In other words, ComStack can be defined as a software stack that provides communication services to the basic software modules and application Layer/application Software. AUTOSAR Communication Stack is a part of the BSW (Basic Software).
AUTOSAR Blockset provides an AUTOSAR editor, dictionary, and blocks for developing Classic Platform as well as blocks and constructs for Basic Software services, including NVRAM Manager and Diagnostics Event Manager, for simulating the BSW services together with your application software model. AUTOSAR editor helps to define AUTOSAR software component properties, interfaces, and data types, and map them to existing Simulink models. It allows you to scale your atomic software components to composition software components and to ECUs.
AUTOSAR is a partnership between automobile manufacturers, suppliers, and tool developers that was formed in 2003. The goal of AUTOSAR is to create a standard software architecture for automotive electronic control units (ECUs). This standardization should lead to increased compatibility between ECUs from different manufacturers, and ultimately to reduced development costs and time-to-market for new vehicles.
The main components of an AUTOSAR model are the Application Layer, the Basic Software Layer, and the Runtime Environment. The Application Layer contains the application-specific code, while the Basic Software Layer contains the reusable code that is shared across applications. The Runtime Environment is the software that runs on the target platform and manages the execution of the applications.
There are a few reasons. First, it allows for easier development and porting of applications across different hardware platforms. Second, it ensures that the applications will be more reliable and easier to maintain. Third, it provides a consistent interface for developers, which makes it easier to develop applications that work together.
I believe that the security aspects of AUTOSAR are very important, and that the standard does a good job of addressing them. In particular, I think that the use of cryptographic signatures and the separation of critical and non-critical components are both important measures that help to ensure the safety and security of AUTOSAR systems.
AUTOSAR is a software architecture for automotive electronics that is widely used in the automotive industry. This architecture allows for the development of complex systems while maintaining a high level of quality and safety. When interviewing for a position that uses AUTOSAR, it is important to be prepared to answer questions about the software. In this article, we will review some of the most common AUTOSAR interview questions and provide tips on how to answer them.
Ans. The AUTOSAR RTE is an acronym for Run-Time Environment which is located at the core of the AUTOSAR ECU. The infrastructure services it offers allow us to communicate between AUTOSAR modules. It generates the methods which help AUTOSAR components to access essential software files like OS or communication services.
There are a lot of popular autosar questions but I’ve shortlisted down some of the major and mostly asked questions. Below is a list of best autosar interview questions and answers-
Ans. The foremost difference between the two structures is that the “CAN base frame” sustains a length of 11 bits for the identifier, and the “CAN extended frame” sustains a length of 29 bits for the identifier, created up of the 11-bit identifier (“base identifier”) and an 18-bit extension (“identifier extension”).
Ans. At an optimum length(40m) the CAN function at a speed of 1Mbps, but if the cable is made longer the speed decreases drastically.
Ans. It helps to minimize the reflection of reference and reduces noise. It keeps the reflection away and problem free and the transmission line must always be terminated.
Basic Software is the standardized layer of software. It offers services to the AUTOSAR Software Components that are essential to run the operational portion of the program. It is not able to perform any function in itself and is located below that of the AUTOSAR RTE (Runtime Environment).
This metamodel for AUTOSAR is an UML2.0 model. The UML2.0 model defines the language that describes AUTOSAR systems as well as related artifacts. It also serves as a graphic illustration of the template that is called diagrams of classes. UML2.0 is used to define the attributes and their relationships.
AUTOSAR RTE represents an acronym for the Run-Time Environment (RTE) that is at the core of the AUTOSAR ECU architecture. It offers the infrastructure services that allow communication among AUTOSAR components. It serves as the method by that AUTOSAR software components can access essential software modules, including the OS and the communication service.
Comstock is a shorthand for Communication Stack. In the AUTOSAR layering architecture, Communication Stack or ComStack assists in-vehicle network communication. In terms of definition, ComStack can be defined as a software stack that provides communications services to the base software modules as well as application layer/application Software. AUTOSAR Communication Stack is a component of BSW (Basic Software).
AUTOSAR Blockset offers an AUTOSAR editor, a dictionary, and blocks to develop Classic Platform as well as blocks and components that support the basic Software services, such as NVRAM Manager and Diagnostics Event Manager for simulating BSW services along with your software model for the application.
