The dependency on software tools for the automotive industry is on a rising trend. At present, it takes more than 100 million lines of codes to build a single passenger car. Research is being carried to develop a fully automated vehicle which will make the dependency on software codes to a greater height. The level 5 vision of the society of automotive engineers will see the advent of driverless cars and other next generation of vehicles which will increase the reliance on software codes. The present generation of vehicles also relies heavily on software codes with improved connectivity to IoT devices.
Open architectures are the need of this hour to help standardize the security elements as much as possible to manage the growing complexity. This will also enable the software teams to comply with the standards. There needs to be a comprehensive coding standard to ensure a safe, reliable and easy to maintain system.
The motor Industry Software Reliability Association (MISRA) and automotive open system architecture (AUTOSAR) are responsible for making software coding standards for automotive industry and the idustries where embedded systems are used. C and C++ are the two most widely used software languages in the automotive industry. Likewise, MISRA C, MISRA C++, and the AUTOSAR C++ are the main coding standards. Established in 1988 MISRA is a set of 127 guidelines for the use of C language in Safety-critical language. Not only the automotive industries but all the industries that use safety-related electronics systems have acknowledged the importance of following MISRA guidelines.
The need to adopt C++ has forced the companies to move to AUTOSAR C++ guidelines. AUTOSAR is established by the partnership of more than 180 companies. With the aim to standardize open system architectures, AUTOSAR is expected to be the future of automotive design guidelines. The AUTOSAR C++ guidelines have been created to comply with the stringent requirements of ISO 26262.
Automotive designing continues to be one of the most fast-paced and innovative markets which always strive to go an extra mile when it comes to safety and reliability.
