ABSTRACT

The latest car generation includes more and more functionalities in body control, car infotainment / connectivity (including Advanced driver assistance systems — ADAS), and clusters. For example, onboard car multimedia is required to be compatible with everyday portable equipment and to play audio/video files from external storage media. Navigation and ADAS are options widely diffused in the automotive market.

Body control applications that are always connected to the battery require high efficiency in light load conditions to limit the overall current consumption, below 100 A typically, and so preserve the battery charge while the engine is off.

Managing real-time platforms for ADAS and automated driving

The move towards ADAS and automated driving marks a milestone in the history of the automotive industry, which possibly (some say most likely) will revolutionize passenger traffic worldwide. From a technical perspective, we are also seeing significant changes being caused by the arrival of new components and by totally new system and software architectures. As a consequence, new business models and new providers are beginning to emerge particularly in the areas of hardware/software and system integration.

Volvo On Call. Phone as key

For decades, drivers have been accustomed to accessing and driving cars with physical keys, but no longer. Volvo Cars said it plans to become the world’s first car manufacturer to offer cars without keys from 2017. Volvo customers will be offered an application for their mobile phones to replace the physical key with a digital key. The innovative Bluetooth-enabled digital key technology, will offer Volvo customers more flexibility, enabling them to benefit from entirely new ways to use and share cars.

Common design wins and next-generation demonstrators driving innovation

Rightware is collaborating with Renesas Electronics Corporation (TSE: 6723) on a demonstration showcasing the capabilities of Renesas’ R-Car H3 System-on-a-Chip (SoC) and Rightware Kanzi®.

The demo presents a high-fidelity configurable digital cluster with infotainment and ADAS (Advanced Driver Assistance Systems) features and showcases the powerful graphics capabilities of the R-Car H3 system-on-chip (SoC) and Imagination Technologies’ PowerVR(TM) GX6650 graphics processing unit (GPU).

Continental Develops a New In-Vehicle Radio Platform

February 15, 2016  by  

conti 2-15-16 SDR-Overview-900x325px-NEUContinental has developed a progressive vehicle radio platform that  allows control of numerous individual functions on one processor, ultimately reducing hardware to a minimum.

Car radios today have to fulfill a large number of consumer requirements, for example digital radio, AM and FM reception, mobile telephony, audio from a variety of sources, large touch screens, soft and hard keys, voice-operated control and smartphone apps.

Even for vehicles in more price driven segments, radios have evolved from simple tuners and amplifiers to proper entertainment hubs. With the dawn of the connected vehicle, as well as different standards and operating systems from consumer electronics, the trends show that the complexity of car radios is increasing.

Rand McNally Introduces OverDryve™ Connected Car Tablet with Multiple Features

February 11, 2016  by  

rand mcnally 2-11-16 332045At the Chicago Auto Show, Rand McNally introduced OverDryve™, a connected-car device that brings luxury car features to mainstream automobiles. OverDryve is a dashboard tablet that provides a combination of entertainment, information, navigation, and safety features that make an ordinary drive more engaging, enjoyable and safe – all for less than $400.

“The vast majority of the 250 million U.S. cars and light trucks on the road today don’t have sophisticated electronics – features such as voice recognition and control, hands-free texting and forward collision detection, just to name a few,” said Stephen Fletcher, CEO of Rand McNally. “OverDryve upgrades ordinary vehicles by providing an advanced connected-car experience for a fraction of the cost of a high-end luxury car.”

Microchip Serial Quad I/O™ (SQI™) Flash Product Offers Extended Voltage, Larger Temperature Range

With the SST26VF SQI product family, Microchip said it has become the only vendor to offer an extended-voltage Serial Quad I/O Flash device in automotive temperature grades.

The new family of products, available in densities of 16-, 32- and 64- Megabits, operates at Automotive Grade 2 and 3 and extends the operating voltage from 2.7V down to 2.3V and temperature up to 105°C.

AVX Conductive Polymer Chip Capacitors Suit Demanding Automotive Applications

February 9, 2016  by  

avx 2-9-16 AVV966 TCQ Series Capacitors PRAVX Corporation has introduced the TCQ Series automotive conductive polymer chip capacitors. Qualified to the Automotive Electronics Council’s AEC-Q200 specification for passive components, the TCQ Series meets the AEC’s 125°C lifetime stability test and humidity bias testing at 85°C and 85% relative humidity for up to 1,000 hours.

“The AEC-Q200 lifetime stability and humidity bias tests are notoriously difficult for polymer capacitors to pass due to inherent material limitations,” said Gordon Hoey, global automotive product marketing manager, AVX. “As such, we based our new TCQ Series automotive conductive polymer chip capacitors on our proven, high reliability TCR Series professional conductive polymer chip capacitors, making several critical improvements to the material, design, and manufacturing processes in order to deliver the enhanced endurance and high stability, harsh environment performance required to achieve AEC-Q200 qualification.”
