Telematics is the intersection of automotive technology and telecommunications, bridging onboard communications within the vehicle to the surrounding infrastructure. Telematics serves many purposes, primarily those of fleet tracking, breakdown assistance, vehicle recovery, emergency calling, and traffic control and is a key component in autonomous driving.
With communications being the primary element of a telematics system, a supplier with a strong focus on automotive networking and connectivity solutions can offer many advantages for developing an effective telematics control unit. Microchip, with its strong heritage in automotive communication technologies such as INICnet™, Ethernet, CAN, LIN, USB, brings leading-edge products and technical expertise to designers of telematics systems.
INICnet technology simplifies automotive infotainment networking with support for Ethernet, Audio, Video, and Control over a single cable. INICnet can coexist with automotive Ethernet to seamlessly interface Internet Protocol (IP)-based data communications across vehicle domains, while providing efficient transport of audio and video data. INICnet does not require development and licensing of additional protocols or software stacks, reducing development costs, and keeping development on schedule. INICnet supports a variety of system management methodologies via IP, or a dedicated control message channel. Data rates of 50 Mbps on UTP or 150 Mbps on coax or optical cabling are supported.
