FUNCTIONAL SAFETY STANDARDS TOP PRIORITY FOR FUTURE AUTOMOTIVE DEPLOYMENT
Auto Tech Review|August 2020
Increasing levels of electronic content in vehicles result in a large amount of software that is required to run the scenes behind the mechanical aspects of a vehicle. Electronic systems in automobiles are part of every section, from the powertrain to comfort and convenience systems as well as all types of safety equipment. This makes electronics and the software running these systems a critical part of the equation for future mobility solutions. In addition, putting standards in place to measure methods of developing, testing and functioning of such electronic systems also becomes highly relevant.

FUNCTIONAL SAFETY STANDARDS

Standards play a key role in bringing all stakeholders onto a level playing field in any industry, and this holds good for the automotive electronics space as well. The standards of ISO 26262 and SAE J3061 cater to the development of electrical and electronic (E/E) systems as well as to cybersecurity, respectively, and play a critical role in the development of electronic systems for the automotive sector, with a bias towards safety systems. ISO 26262 is applicable to E/E safety-focussed systems that are intended to be features in mass-production passenger cars with a maximum gross vehicle weight of up to 3,500 kg.

Meanwhile, the SAE J3061 standard provides guidelines related to vehicle cybersecurity. This is especially important as connected vehicles are being deployed across the globe, and are witnessing growing trends of being targets of cybersecurity attacks. SAE J3061 provides a methodology to design and develop cybersecurity into automotive systems in a comprehensive and systematic manner. It enables these systems to monitor as well as respond to incidents in the field, and to address vulnerabilities in service and operation. The standard’s unique quality lies in its ability to map a process framework for cybersecurity that any company can customise along with its development processes.

The unique feature about ISO 26262 is that it directly deals with safety standards when compared to other traditional standards. Meanwhile, SAE J3061 focusses on the code-level safety, thereby enabling secure coding practices that ensure the codes are not vulnerable to attacks. In addition, it has been observed that the auto industry has adopted multiple safety-related practices from the aerospace sector.

OBJECTIVE ASSESSMENT OF THE SAFETY CONTRIBUTION OF TODAY'S AUTOMOTIVE HEADLAMPS

Good lighting makes a major contribution to road safety. In 2011, the International Commission on Illumination (CIE) presented an evaluation system for headlamps that can objectively assess the quality of illumination and glare limitation. New light sources like LEDs and lighting functions (glare-free high beam, partial high beam) have been available for several years, so that an extension of the proven CIE method is necessary, which takes into account, among other things, changed switch-on and service lives of new lighting functions and represents a generally understandable evaluation system. An evaluation system presented in the following by the Technische Uni versität Darmstadt, which was developed by an encompassing expert commission, is intended to provide representative data and enable an objective evaluation of headlamp performance.

THE RISK OF NOT TRYING NEW FOODS

There’s actually a scientific term for the fear of tasting unfamiliar dishes: food neophobia. It’s not just the name that can be scary. A study from Finland and Estonia found that people with this trait eat lower-quality diets overall and have an increased risk of type 2 diabetes—regardless of their age, sex, or weight. To add more variety to your diet, you’ll need to be persistent. “An individual may need to try a new food 10 to 15 times before getting accustomed to it,” says study coauthor Heikki Sarin.
