Concept car’s coaxial-cable infotainment system uses MOST technology

16-09-2015 | Microchip Technology | Design & Manufacture

Microchip has announced that PSA Peugeot Citroen is networking the
coaxial-cable infotainment system of its Aircross SUV concept car using
MOST® technology. Specifically, PSA PEUGEOT CITROËN is utilizing Microchip’s
OS81110 and OS81118 MOST150 Intelligent Network Interface Controllers
(INICs), which provide 150 Mbps performance and support all MOST network
data types. The striking Citroen Aircross SUV concept car will be shown at
the 66th International Motor Show (IAA) Cars in Frankfurt, Germany, from
September 17-27, 2015.

Aircross occupants benefit from audio spatialization, for peerless acoustic
comfort. Each of its four seats is equipped with speakers and a microphone
to facilitate dialog between the occupants, or to allow an individual
in-cabin experience. Using these 'sound bubbles', each passenger can choose
who they want to speak to while respecting the relaxation of their fellow
travellers, making the journey a time for calm or communication - the choice
is theirs.

To date, more than 170 million MOST interface controllers have been
installed in 184 car models since 2001. All major carmakers have for many
years successfully implemented MOST technology in their multi-node
infotainment networking systems, as it provides a field-proven, low-risk,
whole-system solution. The MOST150 standard also provides Ethernet or
Internet Protocol networking capabilities. This latest version of MOST
technology continues to predictably and efficiently transport video, audio,
packet and control data throughout the vehicle without time-synchronization
protocols, using dedicated channels for minimal processor overhead in the
main infotainment control unit processors.

“We are very grateful that PSA PEUGEOT CITROËN has chosen our MOST150 Coax
Technology for the rapid prototyping of its bold Aircross SUV concept car,”
said Dan Termer, Microchip’s automotive vice president.

MOST150 also provides 150Mbps performance and proven
electromagnetic-compatibility (EMC) behaviour. All MOST INICs offer
industry-standard hardware interfaces to processor and peripheral devices
for the efficient routing of streaming, packet and control data, which
greatly simplifies module designs. End users can immediately access the
vehicle’s infotainment system, due to the MOST INIC’s ultra-fast network
start-up behaviour.

The MOST Cooperation standards enable automotive OEMs and their Tier 1
suppliers with a proven and well-supported methodology for defining and
implementing high-bandwidth infotainment and Advanced Driver Assistance
(ADAS) systems, including a standard physical layer and a robust method for
system management and control with superior reliability and Quality of
Service (QoS). Using MOST technology also results in reduced weight for
easier compliance with environmental regulations, says the company.
