    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.

          Wireless charging: A wide-bandgap sweet spot?

          Wireless power transfer eliminates worries over compatible connectivity

          By Alix Paultre | June 28, 2017

          wireless chargingExcept for those closeted away in secure labs, working on top-secret projects, electronics engineers (EEs) know by now that wide-bandgap semiconductors outperform silicon devices in just about every way. But, figuring out what actual performance benefits might accrue to a specific application is still something of a mystery. A look at the challenging world of wireless charging might illustrate how next-generation solutions can deliver performance benefits unmatchable in silicon.

            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).

                Which is better? SiC or GaN?

                Proper device selection ensures optimal performance

                By Alix Paultre | June 17, 2017

                 

                It is all well and good to point out that wide-bandgap materials like silicon carbide (SiC) and gallium nitride (GaN) are superior performers to legacy silicon, but what does that really mean to the designer? What application spaces can best benefit from the next generation of semiconductors? There is a difference between frequency-oriented applications like RF and LiDAR and energy-oriented applications like power electronics; wide-bandgap devices, properly chosen, can serve both well.

                  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.
