Since LED technology found its breakthrough in all lighting functions, it comes now to digitalisation. LEDs meet the digital needs; they can be switched on or off individually. Using the matrix function, Audi could optimise the high beam. The next step is about micro mirror arrays with more than one million segments, which allow the exact vehicle contour of an oncoming vehicle to be copied quickly and selectively or enable pedestrians to be warned by marking lights on the road.
THE HAND SIGNAL LOSES ITS MEANING
Classical communication between drivers and road users, such as making eye contact, nodding one’s head or giving hand signs, may no longer be necessary because autonomous driving is advancing. Concerns are arising about safety and also acceptance by pedestrians and cyclists. Many concepts have been proposed for autonomously driving vehicles and automated-driving light systems, so standards have to be discussed. However, there is still no standard. This could lead to important discrepancies between regulations worldwide, making it very difficult and expensive for automobile manufacturers to develop autonomously driving cars for a global market.
The future focus of automotive lighting will no longer only be optimised illumination for the driver, but optimised signal lights for all other road users: first of all for pedestrians and cyclists, but mainly – at least for the next few years – for the huge number of drivers in conventional non-automated cars. Since LEDs found their breakthrough in all lighting functions, the basic technology for digitalisation is now available. LEDs offer a digital benefit: they can be switched on or off individually. New technologies based on semiconductors like lasers, or Organic Light Emitting Diodes (OLEDs) will offer additional possibilities. At Audi, digitalisation started in 2013 with the introduction of matrix beam headlamps.

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.
