    Hardware meets software to secure connected cars

    By Majeed Ahmad | September 10, 2017

     

    The wake-up call delivered by car hackers like Charlie Miller has put the automotive industry into a proactive mode on how to secure increasingly connected vehicles. And the quest for sophisticated security solutions for connected cars is opening new venues for collaboration between chipmakers and software vendors.

    Take, for instance, BlackBerry’s QNX Hypervisor 2.0 software platform that Qualcomm has adopted in its Snapdragon™ 820Am automotive SoCs for the instrument cluster and infotainment systems.

      Components consolidation around power systems marks EV uptake

      By Majeed Ahmad | September 10, 2017

      Volvo’s landmark announcement about ceasing the production of internal combustion engine (ICE) vehicles by 2019 negates the common perception among industry observers that electric vehicles (EVs) lack consumer interest.

      The Swedish automaker has vowed to produce only three types of electric vehicles from 2019 onward: mild electric vehicles featuring 48-volt system, Twin Engine a.k.a.

        Automotive vision: The IP guys get in on the act

        A battle is joined in the most demanding of embedded applications

        By Majeed Ahmad | July 22, 2017

        ARM’s Mali-C71 image signal processor (ISP) is making waves in the automotive space where the DSP-core duo of Tensilica and CEVA have been active players in embedding computer vision into ADAS system-on-chip (SoC) designs. The question is: Will ARM – in its quest to extend its dominance into a new application space– swamp their boats? To some extent that will depend on which of the three solutions is technologically superior

        ARM fields the first automotive-grade ISP at a time when the number of cameras in vehicles is rising, and sensor fusion technologies are getting better every day.

          Software-defined radio SoCs remaking car infotainment

          Simplifies the design, lowers the cost, and shrinks the size of the head unit.

          By Majeed Ahmad | June 26, 2017

          Infotainment—the unsung hero of automotive electronics—is continuously making strides while more chic technologies like ADAS and automated driving are stealing most of the headlines. A single piece of infotainment hardware covering multiple broadcast radio requirements simplifies the design, lowers the cost, and shrinks the size of the head unit.

          Car infotainment is still a major differentiator amid a strong consumer demand.

            Flexing its technology muscle, TI plays a strong hand in automotive radar

            Sensor portfolio addresses long range, short range and in-vehicle applications

            By Patrick Mannion | June 23, 2017

            By integrating a variety of RF, analog and digital components (including DSP and MCU) onto a single CMOS chip, Texas Instruments has staked a claim to all automotive radar applications, both outside and inside the vehicle.

            Primary automotive radar applications can be broadly grouped into corner radars and front radars. Corner radars (rear and front) are typically short-range radar sensors that can be used for blind-spot detection (BSD), lane-change assist (LCA) and front/rear cross-traffic alert (F/RCTA), while front radars are typically mid- and long-range radars responsible for autonomous emergency braking (AEB) and adaptive cruise control (ACC).

              V2X communications: A pointless wait for 5G?

              DSRC is here, now, and could be saving lives

              June 12, 2017

              V2X communications — the ability of a vehicle to communicate with another, or with ambient infrastructure – could vastly enhance transportation safety if deployed on a mass scale. But it remains an unfulfilled dream because there isn’t a universal agreement on communications protocols.

              There are two leading contenders for such a communications standard: Dedicated Short Range Communications (DSRC) and Cellular Vehicle-to-Everything (C-V2X) technology that leverages the commercial cellular network and field equipment managed by Mobile Network Operators (MNOs)

              The 5G Automotive Association (5GAA), whose founding members include Ericsson, Intel, Huawei, Nokia, Qualcomm, Audi, BMW Group and Daimler AG, is lobbying for C-V2X, claiming superior capabilities over DSRC, on more than one front.

                Renault to sell electricity from recycled EV batteries

                Creating a market for used power cells

                June 11, 2017

                Renault-Nissan, the strategic partnership between France’s automobile manufacturer Renault and Japan’s Nissan, is working with energy storage specialist The Mobility House to develop a ‘mega battery’ built from new or used electric car batteries. The move has the potential to effectively reduce the ownership cost of electric vehicles (EV) by creating a secondary recycling market for used lithium-ion batteries that might otherwise be scrapped.

                  The powertrain opportunity is reshaping relationships between chipmakers and their automotive customers

                  Emerging? An integrated, compact power train – including power electronics

                  By Christoph Hammerschmidt | May 26, 2017

                  The electrification of the powertrain – at all levels — is a bonanza for semiconductor companies. From micro hybrids, where 48 V systems are accommodating the need for more on-board power, to all-electric vehicles with batteries capable of delivering many hundreds of volts, semiconductors play a vital role.

                  On average, cars with conventional internal combustion engines today contain semiconductors worth some $350.
