Advanced driver assistance systems and automated driving are a megatrend in the automotive industry. The following questions arise: will vehicle manufacturers still be able to differentiate themselves brand-specifically in the future or will all vehicles be perceived as the same, when being driven? How can a brand DNA be implemented and how to achieve the transfer from funto-drive to fun-to-be-driven? In order to provide solutions, clear driving characteristic goals – in front of the customer – must be defined and the requirements for vehicle systems and components shall be derived from this. But what are driving characteristics in the context of assisted and automated driving and how can those specifically be realised in development? Porsche has addressed this challenge together with the University of Applied Sciences Kempten and MdynamiX.
MOTIVATION
Previous studies of the University of Applied Sciences Kempten and MdynamiX with over 120 test persons and current benchmark vehicles with regard to automated lateral control have shown the following: the functional characteristics and driving characteristics, which are currently achieved, still offer a great upward potential, and customer acceptance is still relatively poor [1-3].
The challenge for vehicle manufacturers in the development of ADAS and Highly Automated Driving (HAD) lies in the additional difficulty of differentiating themselves (brand typically). The brand-specific characteristics and the brand position of the vehicle brands have hardly been taken into account in the ADAS/HAD development. For Porsche, it is very important to design both the product and the brand in the age of ADAS/ HAD so that they can be experienced according to the brand. Customers shall experience special emotions, differentiable from other brands and products.
Using the example of assisted lateral guidance, a generic procedure model should be developed to translate subjective customer experiences into subjective expert evaluations and finally into objective Key Performance Indicators (KPIs) with defined driving manoeuvers [4]. This should make it possible to define objective attribute targets for a Porsche typical characteristic and to validate them at any time in all phases of development – from simulation up to road tests. The procedure model should then be transferable to the assisted longitudinal guidance and to driving functions of higher automation levels.

Sound Generation For Enhanced Road Safety
With an ever-increasing number of fully electric and hybrid vehicles entering the market, we are witnessing a change in the acoustic experience in and around the car. The silent nature of the electric powertrain means that other road users miss the familiar acoustic cues that warn them of an approaching vehicle. To remedy this situation, Harman is working on various noise management solutions.
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.
RAPIDO RE-INNOVATES TO CATER TO POST COVID-19 LAST MILE CONNECTIVITY
The rapid pace of urbanisation in the country has witnessed cities expanding and subsuming surrounding villages and smaller towns, evolving into Tier II and III cities.
FUNCTIONAL SAFETY STANDARDS TOP PRIORITY FOR FUTURE AUTOMOTIVE DEPLOYMENT
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.
“BYD'S EV STRATEGY TO ENCOMPASS MOST FORMS OF TRANSPORTATION NEEDS IN INDIA”
The country’s electric vehicle (EV) ecosystem is grappling with a plethora of challenges even as it is striving to wriggle itself out of the ‘nascent stage’ tag. In an exclusive chat with Auto Tech Review, Zhang Jie Ketsu, Executive Director, BYD India shares his perspective on the current EV scenario and how the company intends to progress faster in the Indian automotive industry
SAFETY IN ELECTRIC AND AUTONOMOUS CARS – SIMULATION OF COMPLEX CRASH SCENARIOS
Electric and autonomous vehicles allow for novel seating arrangements and packaging strategies, presenting new safety challenges. Physical crash testing must be supplemented with virtual simulation to ensure vehicle safety on shorter development cycles. With its Simcenter Madymo MBS software, Siemens provides improved runtimes and the Active Human model, enabling accurate and rapid occupant safety analysis in complex crash scenarios.
KIA SONET – A MIGHTY OFFERING IN THE COMPACT SUV SEGMENT
It wouldn't be wrong to say that Kia Motors India has taken the Indian market by storm in less than 12 months of its presence in the market.
NISSAN'S NEW DIRECTION: ARIYA ALL-ELECTRIC
Marking a key milestone in Nissan’s transformation strategy, Ariya ticks a lot of boxes highlighting the strengths of the global automotive giant.
BETTER SAFETY WITH EMERGENCY BRAKE ASSIST FOR MOTORCYCLES
Rear-end collisions with a slower vehicle suddenly cutting into the lane and intersection accidents with cross-traffic are among the most frequent motorcycle accident types. Continental is now developing an emergency brake assist, which detects an imminent collision with a vehicle ahead or with an obstacle, warns the rider and supports him during braking
ADAS WILL SERVE AS CATALYST FOR IMPROVED VEHICLE SAFETY
The automotive industry across the globe is increasingly focussing on safety.
