Microchip announced that Audi will use MOST technology to network the Audi Virtual Cockpit System in its new premium Q7 SUV model, following a similar deployment of the TT coupe model. Specifically, Audi is using Microchip's OS81110 and OS81118 MOST150 Intelligent Network Interface Controllers (INICs), which provide 150Mbps performance and support all MOST network data types. OS81118 also includes a high-speed USB 2.0 interface (PHY / HSIC) that seamlessly interfaces with the system-on-chip (SoC) processor in the virtual cockpit.
Since 2001, more than 170 million MOST interface controllers have been installed in 184 vehicle models to date. Audi and all major car manufacturers have successfully implemented MOST technology in their multi-node infotainment network systems for many years because it provides field-proven, low-risk, full-system solutions. The MOST150 standard also provides Ethernet or Internet protocol networking capabilities. The latest MOST technology version uses a dedicated channel to minimize processor overhead in the main infotainment control unit processor, allowing the predictable and efficient transmission of video and audio throughout the vehicle without the need for a time synchronization protocol , Packet and control data.
Dan Termer, vice president of automotive at Microchip, said: "Audi has adopted MOST150 technology again in its new Q7 SUV model, and we are very grateful for this. MOST150 also provides 150Mbps performance and mature electromagnetic compatibility (EMC) performance. All MOST INICs provide industry-standard hardware interfaces to processors and peripherals to effectively route flows, packets, and control data, greatly simplifying module design. Thanks to MOST INIC's ultra-fast network startup behavior, end users can immediately Access to the vehicle's infotainment system.
The MOST collaborative standard enables automotive OEMs and their tier one suppliers to use a proven method to define and implement high-bandwidth infotainment and advanced driver assistance (ADAS) systems, including the physical layer of the standard and the use of Method for system management and management. With excellent reliability and quality of service (QoS) control. The company says that using MOST technology can also reduce weight and make it easier to comply with environmental regulations.
